an economic theory of self control the concept of self control is incorporated in a theory of individual intertemporal choice by modeling the individual as an organization the individual at a point in time is assumed to be both a farsighted planner and a myopic doer the resulting conflict is seen to be fundamentally similar to the agency conflict between the owners and managers of a firm both individuals and firms use the same techniques to mitigate the problems which the conflicts create this paper stresses the implications of this agency model and discusses as applications the effect of pensions on saving saving and the timing of income flows and individual discount rates

testing the morale theory of nominal wage rigidity this paper tests the morale theory of nominal wage rigidity according to which firms resist making nominal cuts to workers pay even in adverse economic conditions because such cuts hurt worker morale and productivity the authors analyze data from an employer employee survey they conducted in japan in 2000 that year coincided with a rare spell of deflationary recession which the authors argue is a good setting in which to study how nominal pay cuts affect morale they find that a nominal annual pay freeze experienced by 21 of the sampled workers demoralized workers by reducing their trust in the firm and that even greater demoralization not wholly attributable to reduced trust was associated with a nominal pay cut which affected 17 of the workers the observed negative relationship between nominal pay cuts and morale persists even when the estimation includes controls and firm fixed effects

cultural differences in consumer impatience abstract in this article the authors examine cross cultural variations in how people discount the future specifically they predict that people from western cultures are relatively less patient and therefore discount the future to a greater degree than do people from eastern cultures and thus westerners value immediate consumption relatively more furthermore on the basis of regulatory focus theory the authors predict that when easterners are faced with the threat of a delay in receiving a product i e a prevention loss they are more impatient whereas when westerners are faced with the threat of not being able to enjoy a product early i e a promotion loss their impatience increases this enhanced impatience manifests in preference for expedited consumption of a product purchased online in two studies in both studies the authors used a priming methodology on bicultural singaporean participants the results support the predictions in the second study they also found evidence in support

virtual progress the effect of path characteristics on perceptions of progress and choice in goal oriented services consumers want to get transported from one well defined state start to another destination state without much concern for intermediate states a cost based evaluation of such services should depend on the total cost associated with the service i e the price and the amount of time taken for completion in this paper we demonstrate that the characteristics of the path to the final destination also influence evaluation and choice specifically we show that segments of idle time and travel away from the final destination are seen as obstacles in the progress towards the destination and hence lower the choice likelihood of the path further we show that the earlier such obstacles occur during the service the lower is the choice likelihood we present an analytical model of consumer choice and test its predictions in a series of experiments our results show that in choosing between two services that cover the same displacement in the same time i e identical average progress consumer choice is driven by the perception of progress towards the goal i e byvirtual progress in a final experiment we show that the effects of virtual progress may outweigh the effects of actual average progress

the nexus between financial development and energy consumption in the eu a dynamic panel data analysis abstract the relationship between financial development and energy consumption has newly started to be discussed in energy economics literature this paper investigates this issue in the eu over the period 1990 2011 by using system gmm model no significant relationship is found in the eu27 the empirical results however provide strong evidence of the impact of the financial development on energy consumption in the old members greater financial development leads to an increase in energy consumption regardless of whether financial development stems from banking sector or stock market by contrast we find for the new members that the impact of financial development on energy consumption depends on how financial development is measured using bankindex the impact of financial development displays an inverted u shaped pattern while no significant relationship is detected once it is measured using stockindex

time preference the discounted utility model and health the constant rate discounted utility model is commonly used to represent intertemporal preferences in health care program evaluations this paper examines the appropriateness of this model and argues that the model fails both normatively and descriptively as a representation of individual intertemporal preferences for health outcomes variable rate discounted utility models are more flexible but still require restrictive assumptions and may lead to dynamically inconsistent behaviour the paper concludes by considering two ways of incorporating individual intertemporal preferences in health care program evaluations that allow for complementarity of health outcomes in different time periods

can biomass energy be an efficient policy tool for sustainable development abstract this paper first reviews the potential causality from biomass energy to co2 emissions and economic development within relevant literature later the paper examines statistically the impacts of biomass energy consumption on co2 emissions and gdp in the us to this end paper observes environmental and economic implications of biomass fuel usage throughout energy literature and launches asymmetric causality test to confirm disconfirm the literature output the findings of the tests indicate that biomass energy consumption per capita mitigates co2 emissions per capita and increases gdp per capita eventually upon its output this research asserts that biomass energy consumption can be an efficient policy tool for environmentally sustainable development in the us and that hence biomass production technologies and biomass consumption need to be promoted in other countries as well as in the us on the other hand analyses underline the fact that policy makers should consider as well some potential constraints of biomass energy usage such as land use constraints and carbon leakage from biomass production therefore although this paper explores the remedial impact of biomass on environment and growth one may suggest also that further possible works consider the effects of biomass sources in detail to minimize the some worsening influence of biomass usage on climate change

nexus between non renewable energy demand and economic growth in bangladesh application of maximum entropy bootstrap approach abstract the paper analyzes the causal relationship between energy demand and economic growth in bangladesh using annual time series data from 1980 to 2011 from world development indicator wdi database of the world bank since the results of causal direction are sensitive to the models being employed the paper uses maximum entropy bootstrap meboot due to its superiority to overcome small sample bias and limitation of asymptotic distribution theory to avoid the omitted variables bias the paper uses multivariate framework in production function specification the paper finds that a unidirectional causality runs from economic growth to energy demand which indicates that conservative policy might not harm the bangladesh economy but since economic progress leads higher energy consumption demand side management of energy and exploring renewable energy sources are must the implications are discussed

energy consumption economic growth nexus for pakistan taming the untamed abstract a recent survey of energy growth literature has highlighted the potential trade off between bivariate models that suffer from omitted variable bias and the danger of over parameterization of multivariate models in the individual country setting narayan and smyth 2 this is a serious limitation when the interest is in drawing policy implications for specific countries with short times series of available data the maximum entropy bootstrap approach was used to re examine the nature of causal relationship between energy consumption and economic growth for pakistan where the available time series data was only from 1971 to 2011 unlike the techniques used in much of the earlier literature this approach does not rely on asymptotic methods and therefore leads to robust inference even in small samples moreover the approach can be applied in the presence of non stationarity of any type and structural breaks without requiring data transformation for to achieving stationarity and is not sensitive to specification errors such as those in lag length selection the empirical findings based on both the bivariate as well as the multivariate frameworks supported the conservation hypothesis implying the existence of a unidirectional causality from economic growth to energy consumption

can small victories help win the war evidence from consumer debt management abstract the question of how people should structure goal directed activity to maximize the likelihood of goal attainment is one of theoretical and practical significance in particular should people begin by attempting relatively easy tasks or more difficult ones how might these differing strategies affect the likelihood of completing the overarching goal the authors examine this question in the context of an important goal for a large number of consumers getting out of debt using a data set obtained from a debt settlement firm they find that 1 closing debt accounts is predictive of debt elimination regardless of the dollar balance of the closed accounts whereas 2 the dollar balance of closed accounts is not predictive of debt elimination when controlling for the fraction of accounts closed these findings suggest that completing discrete subtasks might motivate consumers to persist in pursuit of a goal the authors discuss implications for goal pursuit generally and for consumer debt managemen

time tradeoff sequences for analyzing discounting and time inconsistency this paper introduces time tradeoff tto sequences as a general tool to analyze intertemporal choice we give several applications for empirical purposes we can measure discount functions without requiring any measurement of or assumption about utility we can quantitatively measure time inconsistencies and simplify their qualitative tests tto sequences can be administered and analyzed very easily using only pencil and paper for theoretical purposes we use tto sequences to axiomatize quasi hyperbolic discount functions we demonstrate the feasibility of measuring tto sequences in an experiment in which we tested the axiomatizations our findings suggest rejections of several currently popular discount functions and call for the development of new ones it is especially desirable that such discount functions can accommodate increasing impatience

the labor illusion how operational transparency increases perceived value aubiquitous feature of even the fastest self service technology transactions is the wait conventional wisdom and operations theory suggest that the longer people wait the less satisfied they become we demonstrate that because of what we term the labor illusion when websites engage in operational transparency by signaling that they are exerting effort people can actually prefer websites with longer waits to those that return instantaneous results even when those results are identical in five experiments that simulate service experiences in the domains of online travel and online dating we demonstrate the impact of the labor illusion on service value perceptions demonstrate that perceptions of service provider effort induce feelings of reciprocity that together mediate the link between operational transparency and increased valuation and explore boundary conditions and alternative explanations this paper was accepted by pradeep chintagunta and preyas desai special issue editors this paper was accepted by pradeep chintagunta and preyas desai special issue editors

relativity rank and the utility of income relative utility has become an important concept in several disjoint areas of economics i present a cardinal model of income utility based on the supposition that agents care about their rank in the income distribution and that utility is subject to adaptation over time utility levels correspond to the leyden individual welfare function while utility differences yield a version of the prospect theory value function thereby providing a new and shared derivation of each i offer an explanation of some long standing paradoxes in the wellbeing literature and an insight into the links between relative comparisons and loss aversion

revealing the nexus among energy economy system with haken model evidence from china s beijing tianjin hebei region abstract economic growth eg and energy consumption ec are interacting processes critical to regional sustainability the evolution mechanism and the nexus between them in the development process of jing jin ji region which is one of the most important agglomerations in china remain unrevealed systematically first the trends in decoupling state between eg and ec during 2001 2016 are checked with the impact gross domestic product technology igt model then eg and ec are defined as two sub systems to form a whole system with eg as the fast variable and ec as the slow one the evolutional interactions among the two subsystems and the whole system are elaborated through the haken model based on the synergetic theory by identifying changes in the decoupling index dr and the control variables a b 1 and 2 simulated by the haken model it can be demonstrated that the development of beijing reached a relatively good state with synergetic coordination of eg and ec the effect of eg on ec and ec on eg reversed in tianjin from positive to negative and hebei from negative to positive respectively ec kept prompting eg in tianjin and eg kept inhibiting ec in hebei both regions have not achieved a complete synergy of eg and ec calling for further ameliorations in economic development and energy consumption patterns in a transitional period this study is a first attempt to apply haken model in the field of energy and economy from the perspective of synergetics the exploration of the evolutional nexus between eg and ec in the jing jin ji region is expected to provide important references for policy formulation both locally and for other regions

anomalies in intertemporal choice evidence and an interpretation research on decision making under uncertainly has been strongly influenced by the documentation of numerous expected utility eu anomalies behaviors that violate the expected utility axioms the relative lack of progress on the closely related topic of intertemporal choice is partly due to the absence of an analogous set of discounted utility du anomalies we enumerate a set of du anomalies analogous to the eu anomalies and propose a model that accounts for the anomalies as well as other intertemporal choice phenomena incompatible with du we discuss implications for savings behavior estimation of discount rates and choice framing effects

is there one unifying concept of utility an experimental comparison of utility under risk and utility over time the nature of utility is controversial whereas decision theory commonly assumes that utility is context specific applied and empirical decision analysis typically assumes one unifying concept of utility applicable to all decision problems this controversy has hardly been addressed empirically because of the absence of methods to measure utility outside the context of risk we introduce a method to measure utility over time and compare utility under risk and utility over time we distinguish between gains and losses and also measure loss aversion in two experiments we found that utility under risk and utility over time differed and were uncorrelated utility under risk was more curved than utility over time subjects were loss averse both for risk and for time but loss aversion was more pronounced for risk loss aversion over risk and time were uncorrelated this suggests that loss aversion although important in both decision contexts is volatile and subject to framing

disappointment in decision making under uncertainty decision analysis requires that two equally desirable consequences should have the same utility and vice versa most analyses of financial decision making presume that two consequences with the same dollar outcome will be equally preferred however winning the top prize of 10 000 in a lottery may leave one much happier than receiving 10 000 as the lowest prize in a lottery this paper explores the implications of disappointment a psychological reaction caused by comparing the actual outcome of a lottery to one s prior expectations for decision making under uncertainty explicit recognition that decision makers may be paying a premium to avoid potential disappointment provides an interpretation for some known behavioral paradoxes and suggests that decision makers may be sensitive to the manner in which a lottery is resolved the concept of disappointment is integrated into utility theory in a prescriptive model

renewable energy an efficient mechanism to improve gdp abstract this article analyzes the effects of renewable energy on gdp for 116 economies in 2003 through structural equation modeling sem approach in order to decipher the mechanism of how the use of renewables improves macroeconomic efficiency we decompose gdp by the expenditure approach although previous theory predicts positive effects of renewables on capital formation and trade balance the sem results show that renewables have a significant positive influence on capital formation only the result that renewables do not have a significant impact on trade balance implies that renewables do not have an import substitution effect thus we confirm the positive relationship between renewable energy and gdp through the path of increasing capital formation but not for the path of increasing trade balance

migration externalities in chinese cities we analyse the impact of internal migration in china on natives labour market outcomes we find evidence of a large positive correlation of the city share of migrants with natives wages using different sets of control variables and instruments suggests that the effect is causal the large total migrant impact 10 when one moves from the first to the third quartile of the migrant variable distribution arises from gains due to complementarity with natives in the production function 6 4 and from gains due to agglomeration economies 3 3 finally we find some evidence of a stronger effect for skilled natives than for unskilled as expected from theory overall our findings support large nominal wage gains that can be expected from further migration and urbanisation in china

the role of natural gas consumption and trade in tunisia s output this paper examines the impact of natural gas consumption real gross fixed capital formation and trade on the real gdp in case of tunisia over the period of 1980 2010 we used auto regressive distributed lag ardl bounds testing approach to test the existence of long run relationship between the variables the vector error correction method vecm granger approach is applied to test the direction of causal relation between the series our findings indicate the existence of long run relationship among the variables natural gas consumption real gross fixed capital formation and trade add in economic growth natural gas consumption real gross fixed capital formation and real trade granger cause real gdp these findings open up new insights for policy makers to formulate a comprehensive energy policy to sustain economic growth for long run

natural gas consumption and economic growth in pakistan abstract natural gas is a dominant fuel in pakistan it offers the cheapest and a cleaner alternative source of energy this paper examines the relationship of natural gas consumption and economic growth in pakistan we include capital labor and exports in the model with multivariate framework the ardl bounds testing approach to cointegration and innovative accounting approach are employed to investigate the dynamic causality relationships among the variables we find the existence of long run relationship among the variables natural gas consumption capital labor and exports are positively affecting economic growth in pakistan furthermore we support the natural gas consumption led growth hypothesis and suggest that natural gas conservation policies may retard economic growth

the slave trade and the origins of mistrust in africa in a recent study nunn 2008 examines the long term impacts of africa s slave trade he finds that the slave trade which occurred over a period of more than 400 years had a significant negative effect on long term economic development although the article arguably identifies a negative causal relationship between the slave trade and income today the analysis is unable to establish the exact causal mechanisms underlying this reduced form relationship in this article we examine one of the channels through which the slave trade may affect economic development today combining contemporary individual level survey data with historical data on slave shipments by ethnic group we ask whether the slave trade caused a culture of mistrust to develop within africa initially slaves were captured primarily through state organized raids and warfare but as the trade progressed the environment of ubiquitous insecurity caused individuals to turn on others including friends and family members and to kidnap trick and sell each other into slavery sigismund wilhelm koelle 1854 p e h hair 1965 charles piot 1996 we hypothesize that in this environment a culture of mistrust may have evolved which may persist to this day we show that current differences in trust levels within africa can be traced back to the transatlantic and indian ocean slave trades combining contemporary individual level survey data with historical data on slave shipments by ethnic group we find that individuals whose ancestors were heavily raided during the slave trade are less trusting today evidence from a variety of identification strategies suggests that the relationship is causal examining causal mechanisms we show that most of the impact of the slave trade is through factors that are internal to the individual such as cultural norms beliefs and values jel j15 n57 z13

modeling loss aversion and reference dependence effects on brand choice based upon a recently developed multiattribute generalization of prospect theory s value function tversky and kahneman 1991 we argue that consumer choice is influenced by the position of brands relative to multiattribute reference points and that consumers weigh losses from a reference point more than equivalent sized gains loss aversion we sketch implications of this model for understanding brand choice we develop a multinomial logit formulation of a reference dependent choice model calibrating it using scanner data in addition to providing better fit in both estimation and forecast periods than a standard multinomial logit model the model s coefficients demonstrate significant loss aversion as hypothesized we also discuss the implications of a reference dependent view of consumer choice for modeling brand choice demonstrate that loss aversion can account for asymmetric responses to changes in product characteristics and examine other implications for competitive strategy

malaria suitability urbanization and persistence evidence from china over more than 2000 years abstract we show that the climatic potential for plasmodium falciparum malaria transmission constituted a locational fundamental that influenced the spatial distribution of urbanization since the early start of the southward expansion of the han chinese around 200 bce this effect is still detectable in today s distribution of urbanization and economic activity even though the risk of malaria falciparum has been successfully eliminated we do not find any indication of convergence between high and low malaria potential regions after eradication our identification strategy relies on a climate based measure of plasmodium falciparum malaria transmission intensity which is fitted to experimental data on mosquito and parasite development from laboratory studies this measure is exogenous with respect to human population densities

the legacies of forced freedom china s treaty ports abstract this paper investigates the long run development of china s treaty ports from the mid eighteenth century until today focusing on a sample of prefectures on the coast or on the yangtze river i document the dynamic development paths of treaty ports and their neighbors in alternate phases of closedness and openness i also provide suggestive evidence on migration and sector wise growth to understand the advantage of treaty ports in the long run

chaos in power pakistan s electricity crisis abstract pakistan is facing a severe electricity crisis due to a persistent and widening gap between demand and available system generating capacity the worsening of power shortages has become a major political issue reflecting the hardships for individuals and businesses it threatens to undermine the credibility and legitimacy of government and to further stress the social fabric of the country the power crisis did not emerge suddenly it is the direct result of imprudent and reckless energy policies over the last three decades these policies have impeded the development of cheap and abundant domestic energy sources they have also resulted in very inefficient fuel mix choices compromising energy and economic security pakistan s energy bankruptcy is ultimately due to massive institutional and governance failure this paper analyzes the problems confronting pakistan s electricity sector and identifies the key elements of a potential policy response to address the country s severe power crisis

financial development and energy consumption in central and eastern european frontier economies this study examines the impact of financial development on energy consumption in a sample of 9 central and eastern european frontier economies several different measures of financial development are examined including bank related variables and stock market variables the empirical results obtained from dynamic panel demand models show a positive and statistically significant relationship between financial development and energy consumption when financial development is measured using banking variables like deposit money bank assets to gdp financial system deposits to gdp or liquid liabilities to gdp of the three stock market variables investigated only one stock market turnover has a positive and statistically significant impact on energy consumption both short run and long run elasticities are presented the implications of these results for energy policy are discussed

frames of reference and the quality of life asked to choose most people state confidently that they would rather be killed in an automobile accident than to survive a quadraplegic and so we are not surprised to learn that severely disabled people experience a period of devastating depression and disorientation in the wake of their accidents what we do not expect however are the speed and extent to which many of these victims accommodate to their new circumstances within a year s time many quadraplegics report the same mix of moods and emotions as able bodied people do there is also evidence that the blind the retarded and the malformed are no less happy than other people ads for the new york state lottery show participants fantasizing about how their lives would change if they won i d buy the company and fire my boss people who actually do win the lottery report the anticipated rush of euphoria in the weeks after their good fortune followup studies done after several years however indicate that these people are no happier indeed are in many ways less happy than before as a young man fresh out of college i served as a peace corps volunteer in rural nepal my one room house had no electricity no heat no indoor toilet no running water the local diet offered little variety and virtually no meat and yet at no time during my two year stay in nepal did i experience a sense of material deprivation on the contrary my monthly stipend of 40 was much more than most others in my village had and with it i experienced a feeling of prosperity that i have recaptured only in recent years these observations illustrate the critical role of context as a determinant of human satisfaction the neoclassical economic model of choice abstracts from context saying that utility depends only on the level of consumption consumption levels obviously are important and the neoclassical model performs reasonably well in many instances and yet its narrow focus misses something important to predict people s behavior to draw inferences about their well being or to make intelligent policy decisions we must not only know the relevant levels of consumption but also have an appropriate frame of reference within which to evaluate them

the fewer the better number of goals and savings behavior abstract this article examines the effect of the number of goals on consumers savings behavior drawing from research on implementation intention the authors show that under certain conditions presenting a single savings goal leads to greater savings intention and actual savings than presenting multiple savings goals multiple goals typically evoke trade offs among competing goals and thus increase the likelihood that people will remain in a deliberative mind set and defer actions in contrast the authors propose and demonstrate that a single goal evokes a stronger implementation intention which in turn has a greater effect on behavior change they also show that the advantage of a single goal over multiple goals on saving is attenuated when saving is easier to implement or when the multiple savings goals are integrated rather than competing among themselves theoretical and practical implications are discussed

energy consumption and economic growth in china a reconciliation abstract in conventional causality testing based on asymptotic distribution theory there is a high risk of wrongly rejecting the true null of no causality especially when the sample size is as small as typically seen in the literature in this study we offer a formal diagnosis of the existing contradictory results on the causal relationship between energy consumption and real gdp we also employ a time series oriented advanced data generation process to perform simulation based inference for the people s republic of china our study covers the 1971 2007 period and considers five different aggregated and disaggregated energy consumption measures as well as three different lag orders in both a bivariate as well as a multivariate frameworks our maximum entropy bootstrap based analysis which avoids pretest biases and is also robust to type i errors supports the neutrality hypothesis in 53 out of the total of 60 model estimations the strong results show that coarse aggregate data has a limited potential to observe the complex causal linkages between energy consumption and economic growth future policy oriented research on this nexus requires more focused analyses based on sectoral and provincial data

a theory of wage dynamics a dynamic equilibrium model of long term implicit labour contracts under incomplete but symmetric information is developed workers are assumed to be risk averse and of unknown ability or productivity risk neutral firms learn as do workers about each worker s productivity by observing the worker s output over time it is shown that equilibrium contracts provide for wages which never decline with age and increase only when the worker s market value increases above his current wage in addition to characterizing the equilibrium wage contract we also derive some of its implications for the behaviour of aggregate wages across various groups of workers these implications explain some findings in the recent empirical literature on ageearnings profiles in particular our model can explain why earnings may be positively related to experience even after controlling for productivity as some empirical studies have indicated

formal and informal institutional legacies and inward foreign direct investment into firms evidence from china this paper explores the influence of informal institutional legacy on contemporary foreign direct investment fdi this study is situated in the context of china s treaty port era 1842 1943 hypotheses are posited and tested related to how the treaty port policies and overseas chinese communities of cities established during that period created formal and informal institutional legacies that positively influence the likelihood and volume of contemporary inward fdi firms receive this research suggests that despite and because of the cultural revolution s traumatic shock informal institutions helped formal institutions morph into informal rules and thus created a lingering legacy effect drawing on a longitudinal sample of chinese firms data and historical materials that provide information about treaty ports and overseas chinese communities this study finds supporting evidence that informal institutional legacy is important for contemporary fdi and brings history back into the international business literature this study provides practical implications by suggesting that given the increasing turbulence and uncertainties in emerging markets and transnational economies building and maintaining connections with transnational community actors of these countries could take advantage of the informal institutions to mitigate risks and sustain international business activities international investors could also benefit by investing in locales with rich transnational community connections

effects of urbanisation on energy consumption in china as a key issue in china s economic development urbanisation creates increasing pressure on energy supply and the natural environment thus a better understanding of the relationship between urbanisation and energy consumption is necessary for chinese decision makers at various levels to address energy security and sustainable economic and social development this paper empirically investigates the effects of china s urbanisation on residential energy consumption rec and production energy consumption pec through a time series analysis the results show that compared with rural areas urbanisation slows per capita rec growth because of the economy of scale and technological advantages associated with urbanisation but has greater promotional effects on the growth of rec and the improvement of rec structure the economic growth caused by urbanisation most significantly contributes to an increase in pec whereas technological advancement was found to reduce the scale of pec except from 2001 to 2005 finally the structural effect of the energy supply increased rather than decreased china s pec and the effect of industrial structure adjustment on pec was found to be insignificant

energy and economic growth in the usa a multivariate approach abstract this paper examines the causal relationship between gdp and energy use for the period 1947 90 in the usa the relationship between energy use and economic growth has been examined by both biophysical and neoclassical economists in particular several studies have tested for the presence of a causal relationship in the granger sense between energy use and economic growth however these tests do not allow a direct test of the relative explanatory powers of the neoclassical and biophysical models a multivariate adaptation of the test vector autoregression var does allow such a test a var of gdp energy use capital stock and employment is estimated and granger tests for causal relationships between the variables are carried out although there is no evidence that gross energy use granger causes gdp a measure of final energy use adjusted for changing fuel composition does granger cause gdp

the impact of growth energy and financial development on the environment in china a cointegration analysis this article aims to investigate the impact of financial development economic growth and energy consumption on environmental pollution in china from 1953 to 2006 using the autoregressive distributed lag ardl bounds testing procedure the main objective is to examine the long run equilibrium relationship between financial development and environmental pollution the results of the analysis reveal a negative sign for the coefficient of financial development suggesting that financial development in china has not taken place at the expense of environmental pollution on the contrary it is found that financial development has led to a decrease in environmental pollution it is concluded that carbon emissions are mainly determined by income energy consumption and trade openness in the long run moreover the findings confirm the existence of an environmental kuznets curve in the case of china

history institutions and economic performance the legacy of colonial land tenure systems in india we analyze the colonial land revenue institutions set up by the british in india and show that differences in historical property rights institutions lead to sustained differences in economic outcomes areas in which proprietary rights in land were historically given to landlords have significantly lower agricultural investments and productivity in the post independence period than areas in which these rights were given to the cultivators these areas also have significantly lower investments in health and education these differences are not driven by omitted variables or endogeneity problems they probably arise because differences in historical institutions lead to very different policy choices

selection on observed and unobserved variables assessing the effectiveness of catholic schools in this paper we measure the effect of catholic high school attendance on educational attainment and test scores because we do not have a good instrumental variable for catholic school attendance we develop new estimation methods based on the idea that the amount of selection on the observed explanatory variables in a model provides a guide to the amount of selection on the unobservables we also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that would be required if one is to attribute the entire effect of catholic school attendance to selection bias we use our methods to estimate the effect of attending a catholic high school on a variety of outcomes our main conclusion is that catholic high schools substantially increase the probability of graduating from high school and more tentatively attending college we find little evidence of an effect on test scores

colonialism and modern income islands as natural experiments abstract using a new database of islands throughout the atlantic pacific and indian oceans we find a robust positive relationship between the number of years spent as a european colony and current gdp per capita we argue that the nature of discovery and colonization of islands provides random variation in the length and type of colonial experience we instrument for length of colonization using variation in prevailing wind patterns we argue that wind speed and direction had a significant effect on historical colonial rule but do not have a direct effect on gdp today the data also suggest that years as a colony after 1700 are more beneficial than earlier years we also find a discernable pecking order among the colonial powers with years under u s british french and dutch rule having more beneficial effects than spanish or portuguese rule our finding of a strong connection between modern income and years of colonization is conditional on being colonized at all since each of the islands in our da

are wages habit forming evidence from micro data although utility functions play a central role in economics the axiom that utility depends only on the absolute levels of its arguments is rarely tested this paper uses panel data on 2000 british employees who remain with the same employer and who are not promoted from one wave to the next it is shown that one important measure of well being overall job satisfaction is strongly positively correlated with the change in the worker s pay between waves but is unrelated to the current level of pay empirical tests suggest that a reference dependent satisfaction function where individual well being depends on current pay relative to past pay is more consistent with these regression results than are productivity or agency explanations of increasing wage profiles some evidence is presented of greater job satisfaction effects of pay rises for lower paid less well educated and younger workers these results provide some micro evidence consistent with the theory widespread in social science of habituation individuals may become used to any given level of consumption or income as such they tie in with the finding that a country s well being as measured by the average happiness of its citizens is only weakly correlated with its per capita gnp

job duration seniority and earnings an important stylized fact about labor markets is that workers with longer seniority with their current employer have higher earnings than other workers with the same total labor market experience this study shows that workers in longer jobs earn more throughout than workers in a series of shorter jobs and that the measured positive cross sectional return seniority is largely a statistical artifact due to the correlation of seniority with an omitted variable representing the quality of the worker the job or the worker employer match the implication is tha t earnings do not in fact rise very much with seniority copyright 1987 by american economic association

the provision of incentives in firms i ncentives are the essence of economics despite many wide ranging claims about their supposed importance there has been little empirical assessment of incentive provision for workers the purpose of this paper is to critically overview existing work on the provision of incentives since the interests of workers and their employers are not always aligned a large theoretical literature has emphasized how firms design compensation contracts to induce employees to operate in the firm s interest this literature has reached into many areas of compensation and has pointed to a multitude of different mechanisms that can be used to induce workers to act in the interests of their employers these include piece rates options discretionary bonuses promotions profit sharing efficiency wages deferred compensation and so on my objective here is to evaluate this literature in the light of a growing empirical literature on compensation where possible i will address the literature from two perspectives first an underlying assumption of this literature is that individuals respond to contracts that reward performance accordingly i consider whether agents behave in this way and whether these responses are always in the firm s interest second i address whether firms write contracts with these responses in mind in other words do contracts look like the predictions of the theory incentives are provided to workers

close encounters of two kinds false alarms and dashed hopes people are frequently exposed to potentially attractive events that are subsequently and unexpectedly reversed and to potentially painful events which are also unexpectedly reversed in the process of being returned to the initial asset position does the sequence in which the positive and negative events occur matter this issue of the combined effect of pleasurable and painful stimuli has received scant theoretical or empirical attention we attempt to fill this lacuna in the literature by studying the retrospective evaluation of surprises that return individuals to their original economic state although such surprises do not change an individual s original economic state we argue that the individual s psychological state changes and the final affective state is among other things a function of the sequence in which the events occur from a theoretical standpoint several perspectives can be brought to bear on the issue for instance one reading of mental accounting based on prospect theory s value function would predict that losses should dominate gains and therefore regardless of sequence people should be unhappy when exposed to two economically equivalent outcomes of different signs conversely the literature on intertemporal choice would suggest that a series that ends on an up note is preferred to a series that ends on a down note because people like to defer gratification so that they may savor positive outcomes similarly people apparently have a preference for happy endings finally the extant literature on recency effects would predict that the last event in a series should have a disproportionate influence on overall affect our model relies on a shift in the reference point to explain how a surprising reversal of an event will lead to a nonzero evaluation of the sequence we suggest that people s reference points shift immediately but imperfectly after a stimulus is presented intuitively this implies that the first stimulus will shift the reference point in its direction as a result of which the evaluation of a sequence of events in which an initial event is unexpectedly reversed will be more favorable if the first event is a loss than if it is a gain this model captures the unanticipated nature of the second event i e the surprise element by allowing the first event to move the reference point consequently by the time the next event occurs the reference point has been updated as a result of which the zero economic outcome of the sequence yields nonzero utility we further posit that the magnitude of the reference point shift should be affected by the time elapsed between the two stimuli specifically the reference point shifts gradually with time until it is fully updated consequently the final affective state of the sequence is also a function of the temporal distance between the two events the main predictions of the model were empirically supported first in a survey using a mall intercept sample subsequently we conducted a study of student subjects involving a coin tossing game in which real money was at stake and in which subjects in one condition experienced the second outcome after a two day delay our results from this second study supported the model s prediction regarding the impact of the elapsed time between the events the experimental tasks involved surprising reversals of initial outcomes thus ensuring that savoring dread types of explanations which require that subjects anticipate the second event could not be operating finally in a series of three follow up studies we tested the claim that the magnitude of outcomes would have an impact on observed affect and consistent with our theory and contrary to recency predictions we observed similar results across different magnitudes while theoretically interesting we should also note that our research is of potential pragmatic significance people s reactions to a series of events is of considerable interest to marketers desirous of generating enhanced attitude affect purchase intention and the like without offering economic inducements such as rebates coupons or other costly discounts additionally public policy officials may be interested in protecting people from being manipulated into purchasing a product simply because of changes in the sequence in which a series of offers is made by the merchant

are earnings profiles steeper than productivity profiles we test competing explanations of rising age earnings profiles by obtaining direct estimates of marginal productivity differentials between workers in different age groups and comparing these to associated earnings differentials using contemporary data from israeli manufacturing firms the results indicate that controlling for other productive inputs and firm characteristics for the unskilled or less skilled workers who represent most of the workers in our sample both earnings and productivity profiles are upward sloping moreover these profiles mirror each other closely and are statistically indistinguishable however the estimates of the profiles are sufficiently imprecise that even sizable deviations between point estimates of earnings growth and productivity growth would not be statistically significant while we view the results as most consistent with a general human capital model of rising earnings profiles over the life cycle there is not strong evidence with which to reject alternative models

factor endowments inequality and paths of development among new world economies whereas traditional explanations of differences in long run paths of development across the americas generally point to the significance of differences in national heritage or religion we highlight the relevance of stark contrasts in the degree of inequality in wealth human capital and political power in accounting for how fundamental economic institutions evolved over time we argue moreover that the roots of these disparities in the extent of inequality lay in differences in the initial factor endowments dating back to the era of european colonization we document through comparative studies of suffrage public land and schooling policies systematic patterns by which societies in the americas that began with more extreme inequality or heterogeneity in the population were more likely to develop institutional structures that greatly advantaged members of elite classes and disadvantaging the bulk of the population by providing them with more political influence and access to economic opportunities the clear implication is that institutions should not be presumed to be exogenous economists need to learn more about where they come from to understand their relation to economic development our findings not only contribute to our knowledge of why extreme differences in the extent of inequality across new world economies have persisted for centuries but also to the study of processes of long run economic growth past and present

a multivariate cointegration analysis of the role of energy in the us macroeconomy abstract this paper extends my previous analysis of the causal relationship of gdp and energy use in the usa in the post war period a majority of the relevant variables are integrated justifying a cointegration analysis the results show that cointegration does occur and that energy input cannot be excluded from the cointegration space the results are plausible in terms of macroeconomic dynamics the results are similar to my previous granger causality results and contradict claims in the literature based on bivariate models that there is no cointegration between energy and output

energy consumption and economic growth the case of oil exporting countries this paper examines the causal relationship between the per capita energy consumption and the per capita gdp in a panel of 11 selected oil exporting countries by using panel unit root tests and panel cointegration analysis the results show a unidirectional strong causality from economic growth to energy consumption for the oil exporting countries the findings have practical policy implications for decision makers in the area of macroeconomic planning in most major oil exporting countries government policies keep domestic prices bellow free market level resulting in high levels of domestic energy consumption the results imply that the energy conservation through reforming energy price policies has no damaging repercussions on economic growth for this group of countries

when does money make money more important survey and experimental evidence the authors investigate how the amount and source of income affects the importance placed on money using a longitudinal analysis of the british household panel survey and evidence from two laboratory experiments they found that larger amounts of money received for labor were associated with individuals placing greater importance on money but this effect did not hold for money not related to work the longitudinal survey analysis demonstrated these differential effects of the source of income on money s importance while holding constant stable individual differences the experiments provide causal evidence that the source of income has an effect on the importance of money as well as on the effort expended to earn more money the authors results suggest that even as individual differences in the importance placed on money may affect peoples income depending on its source income can also affect the importance people place on money

self command in practice in policy and in a theory of rational choice an increasingly familiar occurrence for obstetricians is being asked by patients to withhold anesthesia during delivery the physician often proposes that a facemask be put beside the patient who may inhale nitrous oxide as she needs it but some determined patients ask that no such opportunity be provided if gas is available they will use it and they want not to be able to the request is interesting for decision theory and raises questions of ethics policy and physician responsibility even if the woman is merely making a mistake if she simply does not know how painful labor will be and how glad she will be even in retrospect if the pain is relieved but some women who make this request have had earlier deliveries during which they demanded anesthesia and received it they are acquainted with the pain they anticipate asking for relief and they want it withheld when they do they expect to regret afterwards any recourse to anesthesia this particular instance of attempted selfdenial has features that are special but many that are common the woman is so far as we know in good health physically and mentally she anticipates a transient period when her usual values and preferences will be suspended or inaccessible she has reasons for wanting to frustrate her own wishes at the critical time she needs cooperation she may ratify her choice afterward by expressing herself grateful that no anesthesia was offered even when requested there are ethical dilemmas and legal issues and there is conflict if say the husband disagrees with the physician in the delivery room about what his wife really wants

do urbanization and industrialization affect energy intensity in developing countries abstract against a backdrop of concerns about climate change peak oil and energy security issues reducing energy intensity is often advocated as a way to at least partially mitigate these impacts this study uses recently developed heterogeneous panel regression techniques like mean group estimators and common correlated effects estimators to model the impact that income urbanization and industrialization has on energy intensity for a panel of 76 developing countries in the long run a 1 increase in income reduces energy intensity by 0 45 to 0 35 long run industrialization elasticities are in the range 0 07 to 0 12 the impact of urbanization on energy intensity is mixed in specifications where the estimated coefficient on urbanization is statistically significant it is slightly larger than unity the implications of these results for energy policy are discussed

media bias in china this paper examines whether and how market competition affected the political bias of government owned newspapers in china from 1981 to 2011 we measure media bias based on coverage of government mouthpiece content propaganda relative to commercial content we first find that a reform that forced newspaper exits reduced competition affected media bias by increasing product specialization with some papers focusing on propaganda and others on commercial content second lower level governments produce less biased content and launch commercial newspapers earlier eroding higher level governments political goals third bottom up competition intensifies the politico economic tradeoff leading to product proliferation and less audience exposure to propaganda

do wages rise with job seniority many previous studies have found a strong positive effect of job seniority tenure on wages this paper re examines the evidence using a simple instrumental variables scheme to deal with the fact that tenure is likely to be related to unobserved individual and job characteristics that affect the wage we use the variation of tenure over a given job match as the principal instrumental variable for tenure the variation in tenure over the job is uncorrelated by construction with the fixed individual and job match specific components of the error term of the wage equation our main finding is that the partial effect of tenure on wages is small and that general labour market experience and job shopping account for most wage growth over a career the strong cross section relationship between tenure and wages is due primarily to heterogeneity bias prior researchers see mincer and jovanovic 1981 bartel and borjas 1981 borjas 1981 cline 1979 and mellow 1981 and many others have established that job seniority has a strong positive relationship with wage rates in a cross section or a cross section time series of individuals in this paper we re evaluate the evidence concerning the partial effects on wages of job seniority tenure and total labour market experience the extent to which wages rise with tenure is important for several reasons first and foremost the wage tenure profile is a fundamental question about the structure of earnings over careers second the wage tenure profile is a key determinant of the extent to which the earnings power of individuals is tied to specific jobs and it is important for assessment of the losses suffered by displaced workers hamermesh 1984 third evidence that wages rise with job tenure has been used to explain the decline in quits with tenure since the wage growth on the current job lowers the probability that the worker will locate a superior alternative a growing theoretical literature surveyed in parsons 1984 has taken the evidence of a strong wage tenure profile at face value and sought to provide an explanation for the relationship the most prominent explanation is the theory of specific human capital oi 1962 becker 1962 mincer 1974 parsons 1972 kuratani 1973 and hashimoto 1980 in which the growth of wages with tenure holding experience constant is attributed to the worker s share of investments in firm specific skills more recently lazear 1981 has presented a supervision model of wage growth in which firms defer compensation as a means of inducing workers not to shirk freeman 1977 and harris and holmstrom 1982 provide an explanation for wage growth based on an insurance motive salop and salop 1976 nickell 1976 and guasch and weiss 1982 present adverse selection models of wage growth in which firms use a wage tenure profile as a

it s not what you get but when you get it the effect of gift sequence on deposit balances and customer sentiment in a commercial bank abstract the authors examine the impact of gifts on deposit balances and customer satisfaction in a longitudinal field experiment conducted at a commercial bank they find that gifts increased deposit balances survey response rates and customer satisfaction compared with the no gift control they manipulated several factors within the gift treatment gift type the accompanying message and the sequence of gift value which improved 35 then 100 gift worsened 100 then 35 gift or was a single gift a highly detrimental effect of decreasing gift value occurred on deposit balances this deterioration aversion persisted in a long term follow up analysis of deposit balances a vignette experiment replicates deterioration aversion and extends the results demonstrating increased effectiveness of improving gifts over constant gift sequences and indicating that the mechanism underlying deterioration aversion involves the violation of expectations

the energy gdp nexus addressing an old question with new methods abstract this paper reassesses the causal relationship between per capita energy use and gross domestic product while controlling for capital and labour productivity inputs in a panel of 30 oecd countries over the past 40 years the paper uses panel unit root and cointegration testing and specifies an appropriate vector error correction model to analyse the nexus between income and energy use in doing so we contribute to an old debate using modern tools that shed a new light there is some evidence that over the very short run bidirectional causality exists our results also show a strong unidirectional causality running from capital formation and gdp to energy usage in the long run the reverse causality found in recent work is lost we then show that we can reproduce these earlier results in our data if we reproduce a slightly misspecified model for the engle granger two step procedure used in these earlier papers our findings thus imply that results are very sensitive to model misspecification and careful testing of specifications is required our results have some strong policy implications they suggest that policies aimed at reducing energy usage or promoting energy efficiency are not likely to have a detrimental effect on economic growth except over the very short run

beyond homo economicus evidence from experimental economics environmental policies are generally based on a model of the human actor taken from neoclassical economic theory this paper reports on laboratory experiments suggesting weaknesses in this model and describes alternative models correcting these weaknesses one finding is that economic actors tend to be hyperbolic as opposed to exponential discounters who discount the immediate future at a higher rate than the more distant future another finding is that economic actors are not self regarding but rather in many circumstances are strong reciprocators who come to strategic interactions with a propensity to cooperate respond to cooperative behavior by maintaining or increasing cooperation and respond to free riders by retaliating against the offenders even at a personal cost and even when there is no reasonable expectation that future personal gains will flow from such retaliation we discuss some implications for policy analysis 2000 elsevier science b v all rights reserved

analyzing energy consumption and gdp nexus using maximum entropy bootstrap the case of turkey abstract we employ a maximum entropy bootstrap based framework to analyze the energy consumption and real gdp nexus between 1950 and 2006 in turkey our approach provides more accurate inference in comparison to conventional hypothesis tests based on asymptotic theory it also avoids preliminary testing and shape destroying transformations such as differencing and detrending the bivariate analysis as well as a multivariate framework controlling for exchange rate and oil prices shows no evidence of a causal relation our results are robust to both the number of lags and the time period chosen we also perform a cointegration analysis of the data and point out a common misunderstanding in the literature regarding the concept of causation

can cultural norms reduce conflicts confucianism and peasant rebellions in qing china abstract can culture mitigate conflicts triggered by economic shocks in light of the extraordinary emphasis that confucianism places on subordination and pacifism we examine its role in possibly attenuating peasant rebellion within the historical context of china circa 1651 1910 our analysis finds that while crop failure triggers peasant rebellion its effect is significantly smaller in counties characterized by stronger confucian norms as proxied by confucian temples and chaste women this result remains robust after controlling for a long list of covariates and instrumenting confucian norms using ancient confucian sages 500 b c a d 550 to address concerns of measurement error and reverse causality

nuclear energy consumption commercial energy consumption and economic growth in south asia bootstrap panel causality test abstract the objective of the study is to investigate the causal relationship among nuclear energy consumption commercial energy consumption i e oil consumption gas consumption electricity consumption and coal consumption and economic growth in south asian countries namely afghanistan bangladesh bhutan india maldives nepal pakistan and sri lanka over the period of 1975 to 2010 data is analyzed by bootstrap panel granger causality method the results reveal that nuclear energy consumption granger causes economic growth in nepal and pakistan while commercial energy consumption i e oil consumption granger causes economic growth in bangladesh bhutan maldives nepal and srilanka gas consumption granger causes economic growth in bangladesh bhutan india and maldives electricity consumption granger causes economic growth in india and srilanka finally coal consumption granger causes economic growth in bangladesh bhutan nepal and srilanka on the other side economic growth granger causes nuclear energy consumption in pakistan economic growth granger causes oil consumption in bhutan maldives and srilanka economic growth granger causes gas consumption in nepal srilanka and pakistan finally economic growth granger causes electricity consumption economic growth granger causes coal consumption in all south asian countries the findings show that the nature of causality between nuclear energy consumption economic growth and commercial energy consumption economic growth is in favor of the neutrality hypothesis in most of the countries

the needham puzzle why the industrial revolution did not originate in china one of the most intriguing issues for students of chinese history and comparative economic history is why did the industrial revolution not occur in china in the fourteenth century at that time almost every element that economists and historians usually considered to be a major contributing factor to the industrial revolution in late eighteenth century england also existed in china chinese civilization like the civilizations of mesopotamia egypt and india originated from agriculture the first unified empire qin was formed in 221 b c by 300 b c chinese society had developed into a form that had many characteristics of a market economy with most land privately owned a high degree of social division of labor fairly free movement of labor and well functioning factor and product markets this comparatively developed market economy probably created important attitudes toward profit and contributed to the swift diffusion of the best technology in the han dynasty 206 b c a d 220 the iron tipped plow moldboard and seed drill were widely used in the northern part of china where the main crops were millet and wheat the most significant improvements in chinese agriculture came with the population shift from the north to the rice growing areas south of the yangtze river that started at the beginning of the ninth century and especially after the introduction of a new variety known as champa rice from indochina at the beginning of the eleventh century 2 this variety characterized by better drought resistance and faster ripening enabled farmers to extend the agricultural frontier from the lowlands deltas basins and river valleys to the better watered hill areas and allowed production of two and even three crops a year 3

the impact of financial development on energy consumption in emerging economies abstract financial development is often cited as a very important driver of economic growth in emerging economies and it is thus likely that financial development affects energy demand this study uses generalized method of moments estimation techniques to examine the impact of financial development on energy consumption in a sample of emerging countries several different measures of financial development are examined using a panel data set on 22 emerging countries covering the period 1990 2006 the empirical results show a positive and statistically significant relationship between financial development and energy consumption when financial development is measured using stock market variables like stock market capitalization to gdp stock market value traded to gdp and stock market turnover the implications of these results for energy policy are discussed

why isn t growth making us happier utility on the hedonic treadmill abstract a preference structure is constructed grounded in psychological evidence with well being a function of the consumption level and the growth of the variety of goods consumed such preferences are analyzed in an endogenous variety growth model the implications are consistent with the increase in income and the variety of goods consumed in developed economies in the post war period that have not been accompanied by an increase in reported well being moreover the results suggest a connection between the stagnancy of reported well being and diminishing returns in technological change despite an increase in the variety of goods available over time

intertemporal incentives under loss aversion this paper studies the intertemporal allocation of incentives in a repeated moral hazard model with reference dependent preferences as in k oszegi and rabin 2009 besides consumption utility the agent experiences utility from the change in his beliefs about present and future eort and income when eort plans are rational the prospect of being disappointed by the outcome realization equals that of being pleasantly surprised and hence the loss averse agent is on net hurt by news in contrast to the prediction with classical preferences but consistent with real world contracts if consumption utility is not too concave and news about present income carries suciently larger weight in utility than news about future income a contract setting a current

causality between energy and output in the long run though there is a very large literature examining whether energy use granger causes economic output or vice versa this literature is fairly inconclusive almost all existing studies use relatively short time series or panels with a relatively small time dimension additionally many recent papers continue to use what seem to be misspecified models we apply granger causality and cointegration techniques to a swedish time series data set on energy and economic growth spanning 150 years to test whether increases in energy use and energy quality have driven economic growth we show that these techniques are very sensitive to variable definition choice of additional variables in the model and sample periods all of the following appear to make a finding that energy causes growth more likely using multivariate models defining variables to better reflect their theoretical definition using larger samples and including appropriate structural breaks however it is also possible that the relationship between energy and growth has changed over time and that results from recent smaller samples reflect this energy prices have a significant causal impact on both energy use and output

are fluctuations in energy consumption per capita transitory evidence from a panel of pacific island countries this study applies the panel stationarity test developed by carrion i silvestre et al 2005 breaking the panels an application to gdp per capita econometrics journal 8 159 175 to examine the stationarity of energy consumption per capita for a panel of 13 pacific island countries over the period 1980 2005 this test has the advantage that it allows for multiple structural breaks at unknown dates that can differ across countries and can account for all forms of cross sectional correlation between countries the conclusion from the study is that energy consumption per capita in approximately 60 of countries is stationary and that energy consumption per capita for the panel as a whole is stationary the study offers several suggestions for modelling energy consumption and policy making in the pacific islands

the effect of job tenure on wage offers a wage offer can be either acceptable or unacceptable to a worker but in cross sectional and panel data only acceptable wage offers are observed an ols wage equation will not reveal how job tenure affects wage offers but rather will reveal how tenure affects acceptable wage offers by jointly modeling the firm s determination of the wage offer and the worker s decision to accept or reject the offer we are able to estimate the effect of job tenure on wage offers consistently in contrast to the usual ols results we find that job tenure has no statistically significant effect on wage offers

management of natural gas resources and search for alternative renewable energy resources a case study of pakistan abstract energy usage in pakistan has increased rapidly in past few years due to increase in economic growth inadequate and inconsistent supply of energy has created pressure on the industrial and commercial sectors of pakistan and has also affected environment demand has already exceeded supply and load shedding has become common phenomenon due to excessive consumption of energy resources it would become difficult to meet future energy demands this necessitates proper management of existing and exploration of new energy resources energy resource management is highly dependent on the supply and demand pattern this paper highlights the future demands production and supply of energy produced from natural gas based on economic and environmental constraints in pakistan with special emphasis on management of natural gas an attempt has been made by proposing a suitable course of action to meet the rising gas demand a mechanism has been proposed to evaluate pakistan s future gas demand through quantitative analysis of base worst and best chosen option co 2 emission for all cases has also been evaluated the potential constraints and possible solutions to develop alternative renewable energy resources in the country have also been discussed this work will be fruitful for the decision makers responsible for energy planning of the country this work is not only helpful for pakistan but is equally important to other developing countries to manage their energy resources

do workers prefer increasing wage profiles we present survey data challenging the assumption implicit in analyses of labor supply that all else being equal workers prefer declining over increasing wage profiles we test several explanations for our results including that a there is something special about wages e g their association with productivity as opposed to other types of payments that induces the preference for increasing wages b utility depends not only on absolute levels of consumption but also on changes in consumption over time and c respondents who prefer increasing wage profiles are irrational and would change their behavior if the rationale for preferring declining wages were explained

output renewable energy consumption and trade in africa abstract we use panel cointegration techniques to examine the relationship between renewable energy consumption trade and output in a sample of 11 african countries covering the period 1980 2008 the results from panel error correction model reveal that there is evidence of a bidirectional causality between output and exports and between output and imports in both the short and long run however in the short run there is no evidence of causality between output and renewable energy consumption and between trade exports or imports and renewable energy consumption also in the long run there is no causality running from output or trade to renewable energy in the long run our estimations show that renewable energy consumption and trade have a statistically significant and positive impact on output our energy policy recommendations are that national authorities should design appropriate fiscal incentives to encourage the use of renewable energies create more regional economic integration for renewable energy technologies and encourage trade openness because of its positive impact on technology transfer and on output

the relationship between electricity consumption electricity prices and gdp in pakistan abstract this study analyzes the relationship among electricity consumption its price and real gdp at the aggregate and sectoral level in pakistan using annual data for the period 1960 2008 the study finds the presence of unidirectional causality from real economic activity to electricity consumption in particular growth in output in commercial manufacturing and agricultural sectors tend to increase electricity consumption while in residential sector growth in private expenditures is the cause of rising electricity consumption the study concludes that electricity production and management needs to be better integrated with overall economic planning exercises this is essential to avoid electricity shortfalls and unplanned load shedding

reference dependent consumption plans we develop a rational dynamic model in which people are loss averse over changes in beliefs about present and future consumption because changes in wealth are news about future consumption preferences over money are reference dependent if news resonates more when about imminent consump tion than when about future consumption a decision maker might to generate pleasant surprises overconsume early relative to the optimal committed plan increase immediate consumption following surprise wealth increases and delay decreasing consumption following surprise losses since higher wealth mitigates the effect of bad news people exhibit an unambiguous first order precautionary savings motive

energy security measurement a sustainable approach abstract the main objective of this paper is to define new energy security indicator with the long term sustainability and to test it in a sample of 28 european union countries for the period 1990 2012 as well as to determine the level of impact of six different indicators on energy security the previous methodologies for measuring of energy security have been mainly focused on security of supply while not taking into account environmental indicators and the social component the newly proposed indicator energy security index differs from the existing measuring methods precisely in a way that it includes environmental and social aspects energy security index recorded a decline in values in most countries in the period 1990 2000 in the period 2000 2008 the values became positive and after 2008 some countries reported again gradual deterioration the index value varies by year and the biggest positive changes were recorded in the case of the netherlands slovenia and spain the four economically strongest eu countries the united kingdom france germany and italy recorded significantly less fluctuations in energy security over 23 years compared to other countries the data for france and denmark show that an increased share of energy from nuclear and renewable sources can compensate even increased energy import dependence the assessment of impact of individual indicators on energy security index was conducted by using principal component analysis and showed that energy intensity gdp per capita and carbon intensity have the greatest impact the countries of the former eastern bloc are facing particular challenges of energy security which is primarily related to the rapid economic growth and at the same time a high degree of dependence on import of energy generating products in terms of energy security the most stable transition was reported in hungary and poland

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

health insurance market reform and employee compensation the case of pure community rating in new york abstract pure community rating which was enacted to improve access to health insurance in new york s small group market in 1993 prevents carriers from charging different premiums based on the ages of a firm s workers if small firms were adjusting compensation packages prior to reform to offset higher health care costs of older workers then community rating could lead to greater relative wages for older workers post reform and not necessarily induce adverse selection that results in changes in who is insured i present evidence showing that relative wages of older workers in small firms increased in comparison with other states and with large firms within new york following reform

some evidence on the relationship between performance related pay and the shape of the experience earnings profile we investigate the relationship between performance related pay prp and the shape of workers experience earnings profiles in particular we argue that the slope of the profile depends critically upon the degree of equity held by workers in their enterprise as measured by the extent of prp the implication is that the slope of the profile for prp workers falls between those of their zero equity fixed wage and one hundred per cent equity self employed counterparts our empirical analysis of three british data sets namely the british social attitudes survey the british household panel survey and the british family expenditure survey supports this prior in this paper we explore the shape of the experience earnings profile for individuals employed under different types of contracts fixed wage performance related pay prp and self employment contracts we follow lazear 1979 1981 and lazear and moore 1984 in hypothesizing that the slope of the experience earnings profile reflects agency costs and the reduction thereof with increased agency costs inducing steeper profiles if monitoring costs are high firms may implement compensation schemes designed to encourage employees to self select behavior in the firms interests one such scheme defers a substantial amount of compensation until the later years of tenure the resulting experience earnings profile provides a penalty for shirking lazear and moore 1984 we therefore presume that the profiles of workers employed under fixed wage contracts are steeper than those of self employees for whom the issue of agency does not arise because of the duality of principal and owner lazear and moore 1984 the interesting case is that of workers employed under prp if such contracts represent a hybrid between fixed wage and self employment then one would expect their experience earnings profiles to lie somewhere between these two extreme
