target zones and interest rate variability abstract for narrow exchange rate bands and for reasonable parameter values the interest rate differential s asymptotic unconditional variability is increasing in the width of the exchange rate band whereas for wide exchange rate bands it is slowly decreasing in the exchange rate band the interest rate differential s instantaneous conditional variability is decreasing in the width of the exchange rate band a narrow target zone differs from a completely fixed exchange rate regime in that the interest rate differential s instantaneous standard deviation is high and even increases when the zone narrows

micro to macro simulation a primer with a labor market example simulation models now widely used in the physical sciences can also help economists in depicting the actions and interactions of individuals and firms through time such models can be built and run on any personal computer they can illuminate a wide variety of issues that are difficult to analyze with an economist s conventional tool kit and are especially useful in studying dynamic processes microsimulation models allow the analyst to produce simulated aggregate time series that are rigorously consistent with the assumptions made about behavior on the micro level thus simulations provide a means of bridging the micro macro split in economic analysis this article provides an introduction to microsimulation how it works how to do it its potential and its drawbacks it then allows readers even those with no experience in computer programming to work through the details of a simple microsimulation model readers can put this model on their pcs watch it run through its paces and experiment with their own modifications with this model as an example it should be fairly easy to create programs for new models on other subjects for use in theoretical exploration empirical research or classroom demonstrations the demonstration model i present depicts the experience of individual workers during recession and recovery in the labor market as the model runs its internal census bureau performs surveys on the microlevel and sums up to macrolevel variables the model is simple but it has some interesting applications after explaining how to set it up i use it to explore the effect of unemployment insurance on the level of unemployment and to point up a common fallacy in current labor market literature

corporate conservatism and relative compensation this paper demonstrates that in a simple setting with managerial concern for reputation and asymmetric information on ability most managers may refrain from undertaking innovations that stochastically dominate an industry standard common components of uncertainty lead to market inferences of managerial ability based on relative performance managers who undertake the industry standard are consequently evaluated with a more accurate benchmark than those innovating discontinuities in compensation when performance is low because of firings lead managers to have differing valuations of an accurate benchmark depending on type in particular very high and very low ability managers are more likely to undertake superior innovations than those of average ability

analyst reputation communication and information acquisition earlier studies have shown that reputational concerns tend to reduce agents opportunistic behavior however a recent study by morris argued that analysts experts reputational concerns may discourage truthful communication when they try to avoid being perceived as being misaligned with investors in this paper i examine the effect of reputational concerns on communication in a setting where analysts can choose their precision endogenously because both misaligned and aligned analysts want investors to trust their reports in the future both will aim to build a reputation for being aligned in equilibrium aligned analysts will acquire more information than misaligned analysts as a result investors may favorably update their beliefs about the analysts type when the report is proven to be accurate therefore both types of analysts will have reputational incentives to communicate truthfully the paper also derives conditions under which the analysts reputational concerns have a nonmonotonic impact on aligned analysts equilibrium precision choices and investors welfare

on electricity consumption and economic growth in china abstract the invention and application of the electric power technology triggered the second industrial revolution in human history which marked the human society entered the age of electricity electricity provides the sustainable power for economic and social development with the rapid development of economy the electricity consumption is also increasing the increase of electricity consumption has further promoted the progress of the industrial economy in order to achieve the goal of improving the level of economic development while reducing energy consumption it is necessary to reveal the relationship between electricity consumption and economic growth this study is an extensive overview of the literature surrounding this topic in this paper we focus on the relationship between electricity consumption and economic growth in china we first analyze the general situation of china s electricity consumption and economic development then we explore the relationship between china s electricity consumption and economic growth from three dimensions i e the time dimension the regional dimension and the industrial dimension finally we study the key issues in the research of the relationship between electricity consumption and economic growth including variable selection model construction and results discussion this work suggests that the nature of the nexus in china should and can be explored from a wider perspective by developing a suitable integrated methodological framework

material interests moral reputation and crowding out species protection on private land we consider how the reputation of being socially responsible works as an effective source of motivation in protecting a public good such as endangered species this paper investigates the mechanism design for endangered species protection on private land under asymmetric information about reputation and land quality we examine optimal monetary transfer by designing an efficient mechanism which takes into account the crowding out effect of monetary rewards on socially responsible behavior we find landowners who have good reputation contribute more than the optimum level landowners with poor reputation sacrifices information rent rather they buy reputation

nonlinear nonparametric nonessential exchange rate estimation a wide variety of empirical exchange rate mo dels have been estimated over the years but despite the considerable energies that have been devoted to this work the economics profession has remarkably little to show for itself there is little evidence that conclusively links the bilateral exchange rates of typical oecd countries to fundamental macroeconomic determinants of exchange rates such as money output relative prices or interest differentials coefficient estimates are notoriously unstable and frequently mis signed compared with theoretical predictions exchange rate equations do not fit particularly well and forecast no better than the simplest naive alternatives recently a new class of exchange rate models was introduced by paul krugman 1988 these models provide a potential reason for the poor performance of traditional exchange rate models because they are nonlinear if the exchange rate actually depends in a nonlinear way on exogenous macroeconomic fundamentals linear exchange rate models may work poorly even though the exchange rate is closely linked to fundamentals in this paper we provide a brief sketch of some of this work as well as some preliminary evidence on the actual performance of these nonlinear models in our empirical analysis we use a nonparametric estimator that can handle a wide variety of nonlinear phenomena we examine fixed exchange rate regimes where nonlinearities should be quite easy to detect however we do not find strong empirical support for the hypothesis that the incorporation of nonlinear effects significantly improves models of exchange rate determination in section i we briefly review the theoretical literature on nonlinear target zone exchange rate models linking this work to the tests for intrinsic bubbles we draw heavily on recent papers by kenneth froot and maurice obstfeld 1989a b our methodology and data are discussed in section ii section iii contains new empirical tests for nonlinearities in exchange rate models

modeling climate feedbacks to electricity demand the case of china this paper is an empirical investigation of the effects of climate on the use of electricity by consumers and producers in urban and rural areas within china it takes advantage of an unusual combination of temporal and regional data sets in order to estimate temperature as well as price and income elasticities of electricity demand the estimated positive temperature electric power feedback implies a continually increasing use of energy to produce electric power which in china is primarily based on coal in the absence of countervailing measures this will contribute to increased emissions increased atmospheric concentrations of greenhouse gases and increases in greenhouse warming

is the long run relationship between economic growth electricity consumption carbon dioxide emissions and financial development in gulf cooperation council countries robust the relationship between carbon dioxide emissions economic growth electricity consumption and financial development in the gulf cooperation council gcc countries is investigated in this study using panel data for the period of 1980 2012 a number of econometric techniques dynamic ordinary least squares dols fully modified ordinary least squares fmols and the dynamic fixed effect model dfe are applied in order to estimate the long run relationship between the variables the long run relationship is found to be robust across these different econometric specifications no significant short run significant relationship was observed electricity consumption and economic growth have a positive long run relationship with carbon dioxide co2 emissions whilst a negative and significant relationship was found between co2 emissions and financial development the findings imply that electricity consumption and economic growth stimulate co2 emissions in gcc countries while financial development reduces it granger causality results reveal that there is a bidirectional causal link between economic growth and co2 emissions and a unidirectional causal link running from electricity consumption to co2 emissions however there is no causal link between financial development and co2 emissions also impulse response and variance decomposition analysis outline forecasted impacts of economic growth and electricity consumption on future co2 emissions

on the bad reputation of reputational concerns can reputational concerns do any good economists have shown how they lead agents to ignore valuable information to herd and to become overly risk averse we explore how they may be a social blessing an agent may exert effort to become informed about the uncertain benefits of a project a smart agent s efforts make him better informed a dumb agent s efforts are to no avail if an agent does not know his type reputational concerns are socially beneficial if an agent knows his type reputational concerns may be socially beneficial a dumb agent takes inefficient unconventional decisions to mimic a smart agent the latter exerts more effort in order not to be mistaken for a dumb this holds whether or not project rejection is a safe haven for the dumb

on the nexus of financial development economic growth and energy consumption in china new perspective from a gmm panel var approach abstract this paper studies the endogenous relationships among financial development energy consumption and economic growth in china by applying a gmm panel var approach with a panel data of 30 chinese provinces over the period 1996q1 2015q4 financial development is measured by six individual indicators and by a comprehensive indicator obtained through the pca method we also account for regional heterogeneity by dividing our sample into three regions eastern region central region and western region we underline our findings in three aspects first financial development measured by most individual indicators m2 credit revenue of the insurance industry and stock market value and the comprehensive one has a significantly negative impact on economic growth second energy consumption can significantly contribute to economic growth in all regions while no feedback effect is found except in the western region this result is further supported by the granger causality tests last financial development in the sense of m2 credit stock turnover and the comprehensive indicator can significantly lessen energy consumption in all regions but this inhibitory effect is found to be largest in the western region followed by the eastern region and be smallest in the central region the granger causality tests confirm further the existence of heterogeneity across regions a bidirectional granger causality between the two variables is found in the eastern region a unidirectional granger causality running from energy consumption to financial development is identified in the central region and no significant causal relationship shows up in the western region our findings provide valuable policy implications for china heading for a green economic growth

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

why is electricity consumption inconsistent with economic growth in china studies have indicated that there exists a relatively stable and positive correlation between electricity consumption and economic growth and there should not be a large deviation between them however the deviation between electricity consumption and economic growth in china during the asian financial crisis and global economic crisis sparks intense debates we attempt to explain the deviation from the perspective of inventory investment adjustment in the business cycle using the svar model in this paper the results show that the effects of inventory investment adjustment shock and electricity consumption structure shock on the deviation are positive but tend to be negative for electricity efficiency shock the results of historical decomposition of these shocks also show that the inventory investment adjustment shock is the main factor that influences the deviation during the global economic crisis economic fluctuation in the short term can not change the economic development pattern and the characteristics of electricity demand once the economy returns to stable growth the deviation between electricity consumption and economic growth will shrink and disappear soon

target zones and exchange rate dynamics this paper develops a simple model of exchange rate behavior under a target zone regime it shows that the expectation that monetary policy will be adjusted to limit exchange rate variation affects exchange rate behavior even when the exchange rate lies inside the zone and is thus not being defended actively somewhat surprisingly the analysis of target zones turns out to have a strong formal similarity to problems in option pricing and investment under uncertainty

sectoral analysis of the causal relationship between electricity consumption and real output in pakistan this study uses the annual data from 1972 to 2010 to assess the causal relationship between electricity consumption and real output at the aggregate and sectoral levels in pakistan this study covers three main economic sectors in pakistan namely agricultural manufacturing and services sectors our cointegration results reveal that the variables are cointegrated at the aggregate and sectoral levels at the aggregate level we find that there is uni directional granger causality running from electricity consumption to real output in pakistan at the sectoral level we find that electricity consumption granger causes real output in the manufacturing and services sectors however there is no causal relationship between electricity consumption and real output in the agricultural sector the policy implication of these results is that electricity conservation policies in general would deteriorate the process of economic growth as well as the real output in the manufacturing and services sectors in pakistan nevertheless we suggest the pakistani government to implement the electricity conservation policies merely to the agricultural sector because such policies may have less or no adverse impact on its real output

inconsistency of economic growth and electricity consumption in china a panel var approach abstract china has the largest electricity system in the world which is undergoing a critical market reform based on the panel data in 2000 to 2016 of china this paper tries to explain theinconsistency between electricity consumption and economic growth for example in 2015 gdp growth rate was close to 6 9 but with only 2 9 growth in electricity consumption however in 2018 a 6 6 growth in gdp required an 8 5 electricity growth the results explain the reasons for inconsistency and identify the key factors we find that the increase in inventory fixed capital and industrial electricity consumption will narrow the gap when economy grows faster than electricity consumption and widen the gap on the contrary heterogeneity exists among regions the model and variables seem most convincing in explaining the situation in the western region which is most similar to the full sample of china feedback effect is also observed between electricity consumption and economic growth in most parts of china by granger test the findings provides suggestions for the policy makers in making power planning in an effort to avoid large power shortage or surplus

quantitative modelling of electricity consumption using computational intelligence aided design abstract high electricity consumption is of concern to the world for a variety of reasons including its social economic environmental coupled impacts on well being of individuals social life and the federal energy policies this paper proposes a quantitative model to examine the long term relationship between annual electricity consumption and its major macroeconomic variables including gross domestic product electricity price efficiency economic structure and carbon dioxide emission using computational intelligence aided design ciad it develops a firefly algorithm with variable population favp to obtain the parameters of the electricity consumption model through optimising two proposed trend indices moving mean of the average precision mmap and moving mean of standard derivation mmstd the model is validated with empirical electricity consumption data in china between 1980 and 2012 based on which the error of approximations between 1980 and 2009 is 15 and the error of predictions between 2010 and 2012 is 8 5 the main contributions of this research are to develop 1 a novel quantitative model that can accurately predict the social economic and environmental coupled impacts on the annual electricity demands 2 the conceptual ciad framework 3 favp algorithm and 4 two new trend indices of mmap and mmstd the findings of this research can assist the decision makers in resolving the conflict between energy consumption growth and carbon emission reduction without dooming the economic prosperity in the long run

toward to economic growth without emission growth the role of urbanization and industrialization in china and india abstract the contradiction between economic growth and carbon emissions in china and india is the most prominent in the world both countries have faced tremendous pressures to curb carbon emissions because they are major source of new added emission sources meanwhile both countries have faced greater pressures to achieve industrialization and urbanization in order to eradicate poverty better understanding the decoupling status and its drivers can serve to develop effective policy to achieve economic growth without an increase in emission this paper comparatively analyses the decoupling effect of the economic growth from the carbon emissions as well as its drivers during the period 1980 2014 in china and india the tapio decoupling model was used to analyze the decoupling status and the co integration theory and the impulse response functions were applied to investigate the effects of urbanization industrialization per capita gdp and carbon emission intensity to decoupling the results show that china mainly performed a weak decoupling of economic growth from carbon emissions in 1980 2014 while the decoupling status of india was no regular in china carbon emission intensity is the biggest contributor of decoupling followed by urbanization per capita gdp and industrialization in india the biggest driver of decoupling is also the carbon emission intensity followed by urbanization industrialization and per capita gdp therefore improving energy efficiency is the best policy to toward economic growth without emission growth in china and india

managerial incentive problems a dynamic perspective the paper studies how a person s concern for a future career may influence his or her incentives to put in effort or make decisions on the job in the model the person s productive abilities are revealed over time through observations of performance there are no explicit output contingent contracts but since the wage in each period is based on expected output and expected output depends on assessed ability an implicit contract links today s performance to future wages an incentive problem arises from the person s ability and desire to influence the learning process and therefore the wage process by taking unobserved actions that affect today s performance the fundamental incongruity in preferences is between the individual s concern for human capital returns and the firm s concern for financial returns the two need be only weakly related it is shown that career motives can be beneficial as well as detrimental depending on how well the two kinds of capital returns are aligned it is well understood by now that informational externalities may place special demands on the organization of economic exchange simple price mediated markets will frequently fail in the presence of asymmetric information in that case more elaborate contractual arrangements have to be used as substitutes for the price system lately considerable effort has been devoted to the analysis of contracting under incomplete information with the objective to understand the range of economic institutions that emerge in response to the failure of the price system the analysis of moral hazard has played a prominent role in this development moral hazard problems arise when for some reason or another transacting parties cannot contract contingent on the delivery of the good for instance in buying labour services it may be that the amount of labour supplied is not directly observable precluding a simple exchange of wage for labour as a partial remedy to this problem an imperfect mutually observed signal about the supply of labour can be used as a proxy in the contract frequently output is taken as such a proxy the drawback is that output is often influenced by other factors than labour input which induce undesirable risk into the contract one is therefore faced with a tradeoff between allocating risk associated with incomplete observability and providing incentives for a proper supply of labour gaining insight into this tradeoff is important not only for understanding contracting in the small e g managerial incentive schemes but also because it is closely related to the fundamental tension between equity and efficiency in the society as a whole while our understanding of moral hazard has advanced a lot in past years it is clear that much work remains an important question that has received little attention until

social status and economic performance a survey abstract this survey combines ideas and results from sociology and economics recognizing that economic decisions are often shaped by social concerns and influences based on the sociological literature we define social status and describe its measurement we then describe the role of social status in economic analysis of saving and consumption wages and economic growth we review recent work on status determination in equilibrium including evolutionary models we conclude with some remarks on the need for further interaction between sociology and economics

dynamics of electricity consumption oil price and economic growth global perspective this study uses the data from 157 countries from 1960 to 2014 to analyze the relationship between economic growth electricity consumption oil prices capital and labor the economic growth of developing countries with industrial infrastructure has a more significant association with electricity consumption than oil prices we use oil prices and electricity consumption jointly to study highly predictive observations for economic growth the data are categorized by income oecd and regional levels the panel cointegration long run parameter estimation and pool mean group tests are used to analyze the cointegration and short run and long run relationships between the variables the empirical results indicate the presence of cointegration between the variables the presence of feedback effects between electricity consumption and economic growth oil prices and economic growth is valid these findings confirm that in spite of the oil prices developing countries rely heavily on electricity consumption for economic growth in the short run growth and feedback effects suggest that more vigorous electricity policies should be implemented to attain sustainable economic growth for the long term

social norms and random matching games abstract nash equilibrium has been tremendously useful in understanding economic problems in which strategic behavior is important the theoretical foundations of the solution concept often include the assumption that the game to be played is common knowledge an unrealistic assumption in games with many players we introduce the concept of norm equilibrium for random matching games a norm equilibrium is a nash equilibrium that relies on substantially less information than common knowledge of the game we use norm equilibria to provide a folk theorem for random matching games and to analyze increasing numbers of players in a random matching game journal of economic literature classification numbers c70 c72

class systems and the enforcement of social norms abstract we analyze a model in which there is socially inefficient competition among people in this model self enforcing social norms can potentially control the inefficient competition however the inefficient behavior often cannot be suppressed in equilibrium among those with the lowest income due to the ineffectiveness of sanctions against those in the society with the least to lose we demonstrate that in such cases it may be possible for society to be divided into distinct classes with inefficient behavior suppressed in the upper classes but not in the lower

managerial career concerns and investments in information we extend the implicit incentives literature by analyzing how career concerns affect a riskneutral manager s decision about how much to learn about a project before investing in it the manager has unknown ability that determines the probability with which a good project is available so the market updates ability assessments from project outcomes while project choice is efficient in equilibrium an unobservable investment in the precision of project evaluation allows the manager to control the probabilities of future reputational states this distorts his investment in precision above first best when project payoffs can be observed only on accepted projects

equilibrium political budget cycles political business cycle theories generally rely on nominal rigidities and voter myopia this paper offers an equilibrium theory that preserves some basic insights from earlier models though with significant refinements the political budget cycle emphasized here is in fiscal policy rather than output and inflation it arises via a multidimensional signal process one can consider the welfare implications of proposals to mitigate the cycle and the effects of altering the electoral structure copyright 1990 by american economic association

a note on the electricity growth nexus in lao pdr abstract this paper investigates the relationship between electricity consumption and economic growth in laos by applying the ardl bounds testing approach to cointegration and granger causality tests our results confirm the existence of a long run relationship between electricity consumption and economic growth in addition we found unidirectional causality running from economic growth to electricity consumption in the long run supporting the conservation hypothesis

the evolution of attitudes to risk lottery tickets and relative wealth abstract individual attitudes to risk are examined in an evolutionary model males obtain more offspring as a consequence of greater wealth both directly and because this attracts more mates the second effect induces gambling driven by relative wealth and can create pareto inefficiency fair bets involving small losses and large gains are taken if any fair bets at all are taken altogether the model accords with observations concerning bets taken and declined by typical individuals despite settings of widely varying per capita wealth journal of economic literature classification numbers c72 d81

the consequences of endogenizing information for the performance of a sequential decision procedure we analyse the implications of endogenizing information collection and reputational concerns for the performance of a sequential decision structure in this model two agents decide in a sequence whether to implement a public project the cost of gathering information is private we derive two results first endogenizing information replaces the herding problem with a free rider problem second endogenizing information aggravates the distortionary effect of reputational concerns

social status education and growth this paper investigates the implications of social rewards on the allocation of talent in society and consequently on the process of economic growth we consider two sources of heterogeneity among workers nonwage income and innate ability a greater emphasis on status may induce the wrong individuals that is those with low ability and high wealth to acquire schooling causing workers with high ability and low wealth to leave the growth enhancing industries this crowding out effect taken alone discourages growth growth may be enhanced by a more egalitarian distribution of wealth which reduces the demand for status

stochastic process switching and the return to gold 1925 the authors analyze and estimate the effect on the dollar sterling exchange rate in the early 1920s of anticipations of the return to the gold standard at prewar parity in the united kingdom these measures are consistent with a class of models of the exchange rate that includes a version of the monetary model and with any fundamentals that follow a random walk with drift contrary to some contemporary views the appreciation of sterling prior to april 1925 appears to have been due to fundamentals such as restrictive monetary policy rather than to the expectation of a change in regime copyright 1990 by royal economic society

china s energy demand and its characteristics in the industrialization and urbanization process a reply zhang and qin 2013 argued that in jiang and lin 2012 the equation form and variable selection should be altered and it was problematic to use regression equation to project the future in this reply we disagree with and will refute some of the points raised in their comments the model that we established was based on the mature economic theory with the variable selections all having economic implications considering the economic development stage china s urbanization will speed up and this will have significant effect on energy consumption therefore urbanization is an indispensable variable for analyzing energy demand in china the scenario design only in terms of the gdp is sufficient for illustrating energy demand trend in china to be understood in a way by most of the people although energy forecast is not that precise it has an important implication for energy policy design especially for china which is in transition and china s energy demand will keep high growth in the mid term

intertemporal optimization of the coal production capacity in china in terms of uncertain demand economy environment and energy security abstract as coal is the main energy source in china coal overcapacity and undercapacity have negative impacts on the economy environment and energy security to reveal the optimal production capacity opc an intertemporal optimization model under uncertainty is established by a combined dynamic programming influence factor scenario analysis monte carlo method dp if sa mc the opcs in 1990 2025 are solved to minimize the expected cost to the economy and environment driven by the production capacity pc under energy security in addition we define and calculate the pc deviation pcd or the deviation of the actual pc apc from the opc the results show that compared with the apc the opc has advantages of more stable development more timely adjustment and lower cost and it provides cost savings of 302 857 billion yuan in 1990 2017 according to pcd china s coal industry existed under the risk of overcapacity in 1990 1999 and 2009 2017 and undercapacity in 2000 2008 and it can experience overcapacity for most of the time without capacity reduction policies in future the optimal management of the pc should be based on the opc and pcd over the next 5 10 years rather than the current capacity utilization rate and focus on overcapacity management in the long run

social status culture and economic performance in analysing the differences in productive capacity among economies it is usual to concentrate on the physical aspects of the population the different attributes of capital including human capital and on the available production technologies societies also differ in culture in ways which are relevant for economic performance the sociological literature recognises that different occupations have different social status and that workers benefit not only from the wage they receive but also from being associated with a particular occupation cultural differences among societies may translate into different status of occupations and can therefore affect the choice of education and occupation and consequently the equilibrium level of output and wages conversely the economic choices of individuals influence the social status of occupations in particular it is well established by sociological research that the social status of an occupation is influenced by economic attributes such as the average wage and the average level of education in the occupation a major objective of our work is to illustrate that sociological and economic approaches can be combined within a unified framework this is in contrast to some social scientists who view the two approaches as competing with each other phelpsbrown i 977 ch 4 in this paper we construct a simple general equilibrium model in which both wages and status are determined endogenously we show that changes in the demand for status triggered by changes in preferences or in income distribution influence the wage structure the level of aggregate output and economic welfare the link between status and aggregate output is created by the fact that differences in occupational status imply occupational wage differences among workers of the same skill the larger is the demand for status the larger is the wage gap and the lower is aggregate output our discussion of status is closely related to the economic analysis of discrimination against ethnic or racial groups becker i 97 i arrow i 973

energy consumption and economic growth nexus in portugal italy greece spain and turkey an ardl bounds test approach 1965 2009 abstract the paper examines the nexus between primary energy consumption and growth in portugal italy greece spain and turkey pigst with annual time series data from 1965 to 2009 pigst are southern european economies which have experienced several episodes that make them of particular interest to the study of periods of economic expansion and stagnation an ardl bounds test approach is a suitable technique to examine energy growth nexus within the context of countries with both sporadic shocks outliers and permanent shocks structural breaks empirical results suggest bidirectional causality between energy and growth in both the long run and short run supporting the feedback hypothesis the results reveal themselves to be robust to panel framework an energy conservation policy will reduce gdp growth while a saving phenomenon is observed since one additional unit of product requires less than one unit of energy

social rewards externalities and stable preferences this paper examines the role of social rewards as a corrective mechanism for activities which generate externalities the focus of this paper is on the circumstances under which social rewards provide effective and feasible incentive mechanism that may replace laws and regulations in particular social mechanism is effective only in a society in which individuals who care about their standing in the society can survive in the long run we show that the nature of economic interaction between matched players influences whether the socially minded individuals survive in the long run and restricts the effectiveness of social rewards however circumstances exist where the socially minded survive even though relative fitness is determined only by economic payoff 1998 elsevier science s a all rights reserved

linear and nonlinear causality between sectoral electricity consumption and economic growth evidence from taiwan this study investigates the linear and nonlinear causality between the total electricity consumption tec and real gross domestic production rgdp unlike previous literature we solve the undetermined relation between rgdp and electricity consumption by classifying tec into industrial sector consumption isc and residential sector consumption rsc as well as investigating how tec isc and rsc influence taiwan s rgdp by using the granger s linear causality test it is shown that i there is a bidirectional causality among tec isc and rgdp but a neutrality between rsc and rgdp with regard to the linear causality and ii there is still a bidirectional causality between tec and rgdp but a unidirectional causality between rsc and rgdp with regard to the nonlinear causality on the basis of i and ii we suggest that the electricity policy formulators loosen the restriction on isc and limit rsc in order to achieve the goal of economic growth

speculative anticipations of sterling s return to gold was keynes wrong the view held by keynes that there was a speculative appreciation of sterling prior to its return to the gold standard has been challenged by gregor smith and todd smith who argue that expectations of return must have weakened the currency the authors demonstrate that the positive but decreasing trend displayed in the exchange rate data is consistent with a pattern of autoregressive convergence in fundamentals and that this continues to be true when there is a positive speculative element based on expectations of an early return hence the key features of the data seem compatible with keynes s views copyright 1994 by royal economic society

politicians decision making with re election concerns abstract we study the impact of elected officials re election concerns on their decisions on whether to undertake new projects the value of a project to a jurisdiction depends in part on its elected official s uncertain ability at providing some public goods our main result is that the elected official s willingness to pay for the project differs from voters willingness to pay if the incumbent official expects to lose win the election then she is willing to pay more less than the project s total value to voters we show how our analysis can be applied to bidding wars among jurisdictions for firms

re investigating the electricity consumption and economic growth nexus in portugal in the previous decades a number of studies have been conducted to analyse the causal relationship between electricity consumption and economic growth in the portuguese economy however the evidence remains controversial because the previous studies do not provide clear causality evidence this might be attributed to the omitted variables bias because most previous studies only focus on the relationship between electricity consumption and economic growth in a bi variate model this paper attempts to re investigate the relationship between electricity consumption and economic growth in portugal using a multivariate model based on the bounds testing approach to cointegration and the granger causality test within the vector error correction model vecm our empirical results confirm the presence of cointegration among the variables moreover there is evidence of bi directional causality between electricity consumption and economic growth in the short and long run this suggests that energy is an important source of economic growth in portugal therefore energy conservation policies should not be implemented because it would deteriorate the process of economic growth and development of the portuguese economy

on committees of experts a committee makes a decision on a project on behalf of the public members of the committee agree on the a priori value of the project and hold additional private information about its consequences they are experts who care about the value of the project and about being considered well informed before voting on the project members can exchange their private information simultaneously we show that reputational concerns make the a priori unconventional decision more attractive and lead committees to show a united front these results hold irrespective of whether information can be manipulated or not also reputational concerns induce members to manipulate information and vote strategically if their preferences differ considerably from those of the member casting the decisive vote our last result is that the optimal voting rule balances the quality of information exchange and the alignment of interests of the decisive voter with those of the public

electricity consumption and metropolitan economic performance in guangzhou 1950 2013 abstract this study analyzes the relationship between electricity consumption and metropolitan economic growth for guangzhou china using 64 years of annual frequency data the capital stock is used as a control variable because of its role in mediating the relationship between energy utilization and economic output empirical results indicate unidirectional granger causality from electricity consumption to metropolitan economic performance in the short run this is consistent with the argument that dependable electricity infrastructure and service can play a vital role in facilitating economic growth implications for conservation efforts and regional development are discussed

electricity consumption and economic growth in nigeria a revisit of the energy growth debate abstract this paper examines the dynamic causal linkages between electricity consumption and economic growth in nigeria within a trivariate vecm for the period 1971 2011 the paper obviates the variable omission bias and the use of cross sectional techniques that characterise most existing studies the results show that there is a distinct causal flow from electricity consumption to economic growth both in the short run and in the long run this finding supports the electricity led growth hypothesis that has been conjectured in the literature the paper urges policy makers in nigeria to implement policies which enhance the generation and consumption of electricity in order to engineer economic growth appropriate monetary policies must also be put in place in order to moderate inflation thus enhancing growth

the roles of reputation and transparency on the behavior of biased experts we analyze situations in which an expert is biased toward some decision but cares also about his reputation in the market for experts the information the expert reveals decreases as his bias moves toward stronger preference for the status quo we show that it is optimal to publicly disclose both the expert s contribution and his identity surprisingly revealing the intensity of the expert s bias doesn t always improve the information he reveals in equilibrium the presence of a second expert raises the first expert s incentives to report truthfully when reports are public but reduces them when they are secret in particular having an option to call another expert may be detrimental in terms of information production if reports are not public finally sequential consultation of experts reduces the information obtained when reports are public but raises it when they are secret

production function with electricity consumption and policy implications in portugal using a sample of quarterly data we investigate the effect of electricity consumption capital formation and financial development on economic growth in portugal a positive negative shock of electricity consumption is estimated to have increased decreased economic growth economic growth is positively affected by positive shock stems in capital a positive negative shock in financial development declines increases economic growth these findings reveal that a portugal is still an energy dependent economy b energy is one of the major inputs for economic growth and development c a conservation energy policy should not be implemented because energy is an important driver of growth d economic growth enhances capital formation and not the opposite hence it appears more relevant to boost economic growth before enhancing capital formation e financial development does not appear to be an important catalyst for economic growth findings also highlight f the relevance of the recent energy policy implemented in portugal and g the need to limit energy imports by means of producing electricity through renewable energy to reduce the external debt level in portugal especially after the 2008 crisis

electricity consumption and economic growth nexus in beijing a causal analysis of quarterly sectoral data abstract traditional energy economy nexus analysis is limited to aggregated and annual data because more detailed energy consumption data are usually not available however probing the disaggregated sectoral data usually provides a deep insight of energy economy nexus at sectoral level which is vital for governments to make proper policies in a timely manner this paper developed a deep research to find detailed quarterly and sectoral nexus between electricity consumption and economic growth sectoral data of electricity consumption and economic growth from 2005q1 to 2016q3 in beijing were exploited to model with granger causality analysis the results show that at the aggregated level there is a unidirectional causality running from economic growth to electricity consumption at sectoral level for the primary sector the electricity consumption impacts its added value with two quarter lagged for the secondary sector and the tertiary sector there is a unidirectional causality running from economic growth to electricity consumption at cross sector level the economic growth of the secondary sector has no impact on that of the tertiary sector while the economic growth of the tertiary sector strongly affects that of the secondary sector in terms of energy saving and emission reduction different policies should be employed in the three sectors beijing should encourage the electrification of the primary sector to stimulate its development beijing should make more efforts on tertiary sector to reduce electricity consumption however these policies should be more prudent while for the secondary sector improving energy efficiency and technological innovation should be paid more attention to

on the cultural transmission of preferences for social status abstract we study the formation of preferences for social status as the result of intergenerational transmission of cultural traits we characterize the behavior of parents with preferences for status in terms of socialization of their children to this particular cultural trait we show that degenerate distributions of the population whereby agents have either all status preferences or all non status preferences are dynamically unstable moreover under some conditions there exists a unique stationary distribution which is non degenerate in which both status and non status preferences co exist in the population and this distribution is locally stable finally we study the dependence of the stable stationary distribution of status preferences on institutional technological and policy parameters which affect agents economic conditions

globalization and the shifting centers of gravity of world s human dynamics implications for sustainability abstract world s human dynamics can be parameterized with metrics that explain the current model of economic growth and its sustainability changes in the world s human dynamics are crucial for understanding the current state of the world which is faced with increasing challenges related to globalization in this paper we propose to analyze the shifting locations of centers of gravity of four basic global indicators these are gross domestic product carbon dioxide emissions population and urban population for the period 1960 2016 the spatial locations of the respective centers of gravity one per year draw some traces that explain at least partially relevant changes on different world s human dynamics at a global level these traces and dynamics are further discussed in addition these traces are fundamental for predicting upcoming trends for the next few years results shown here may help political leaders and policymakers for solving upcoming and future global challenges related to the current economic system and its impact on the environment

herding and anti herding a model of reputational differentiation abstract we analyze a model related to the strategic herding literature where a second expert maximizes his expected second period value by conforming with a first expert herding in contrast to the herding literature we assume that an agent is most valuable if he is the only smart agent if the value of being the only smart agent is sufficiently large the second expert always opposes its predecessor s report otherwise herding may result

income inequality human capital accumulation and economic performance we show that greater income equality implies higher human capital accumulation and economic performance in an overlapping generations model with heterogeneity in income and talent given liquidity constraints and declining marginal utility individuals with a given level of talent receive education if their initial income is higher than a threshold level and the threshold is lower for more talented individuals assuming the more talented create more human capital when educated greater initial income equality for one generation then imply not only higher aggregate human capital accumulated by that generation but an improvement in all subsequent generations initial income distributions

trivariate causality between economic growth urbanisation and electricity consumption in angola cointegration and causality analysis abstract this paper investigates the causal relationship between economic growth urbanisation and electricity consumption in the case of angola while utilizing the data over the period of 1971 2009 we have applied lee and strazicich 2003 the review of economics and statistics 63 1082 1089 2004 working paper department of economics appalachian state university unit root tests to examine the stationarity properties of the series using the gregory hansen structural break cointegration procedure as a complement we employ the ardl bounds test to investigate long run relationships the vecm granger causality test is subsequently used to examine the direction of causality between economic growth urbanisation and electricity consumption our results indicate the existence of long run relationships we further observe evidence in favour of bidirectional causality between electricity consumption and economic growth the feedback hypothesis is also found between urbanisation and economic growth urbanisation and electricity consumption granger cause each other we conclude that angola is energy dependent country consequently the relevant authorities should boost electricity production as one of the means of achieving sustainable economic development in the long run

if homo economicus could choose his own utility function would he want one with a conscience reply in my model of the evolution of honesty 1 i assumed the existence of a signal a blush perhaps extreme values of which served to identify some individuals as being honest with certainty joseph harrington notes that without this assumption honest individuals have difficulty invading a population initially dominated by defectors for readers who do not wish to work through the algebra in his comment the argument is easily summarized in nontechnical terms suppose two honest mutants a and b arrive in an uncountably large population consisting entirely of dishonest persons and suppose that the probability that an honest person exhibits an intense blush is say 0 999 while the corresponding probability for everyone else is only 0 001 when a sees an intense blush on the face of b what will then be his estimate of the probability that b is honest assuming that a knows the laws of elementary probability and corrects for the base rate of honest persons in the population it will be zero when virtually everyone in the population is dishonest even a person with an intense blush will be pegged as dishonest provided that even the smallest fraction of dishonest persons also shows an intense blush with

when second opinions hurt a model of expert advice under career concerns we augment the standard career concerns model by introducing i an action that blocks the information about the true state of the world and ii a second opinion interim news after the initial consultation with the expert in this model the principal s action as well as the expert s message endogenously determine the observability of the states and consequently the assessment of the expert s ability by the principal we show that having access to better interim news could reduce the welfare of the principal due to its strategic effect on the expert s recommendation we also discuss the implication of the results for possible delegation of decision making to another person with different decision parameters

a test of environmental kuznets curve for haze pollution in china evidence from the penal data of 27 capital cities abstract the mounting environmental crisis especially the large scale and continuous haze pollution is the most pressing challenge for china during rapid urbanization process this study is aimed at examining the relationship between haze pollution and economic growth and its turning points for different regions in china based on the panel data of 27 capital cities and municipalities in china during 2011 2015 we constructed the parameter estimation model after conducting the unit root cointegration and hausman tests based on the basic and extended models we find that the relationship between haze pollution and economic growth in china is not a typical inverted u shaped environmental kuznet curve ekc by introducing variables such as industrial structure foreign trade and energy intensity this study demonstrates that adjusting industrial structure and improving energy efficiency are effective means for haze pollution control grouping regressions reveal that regional differences exist in the relationships between haze pollution and economic growth and their tuning points for instance there was a u shaped relationship for the central region while there were inverted n shaped relationships for eastern western and northeastern regions policy implications are thus summarized for different regions in terms of balancing economic growth and environmental protection

shaping china s energy security the impact of domestic reforms this paper is a subsequent study of china s energy security situation which concludes that china s energy security has not improved over 30 years of economic reform the objective of the study is to explore qualitatively why the energy security situation has not improved to answer the why question the study opens up a new perspective by analyzing the relationship between energy security and energy policies from the macroeconomic reform perspective this study discusses major reforms that took place over 30 years it is found that china s macroeconomic reform has restricted the formation of china s energy policies and determined its energy security situation in essence china s energy policies are only a reaction to the macroeconomic measures in other words china s energy policies are not originally intended to improve energy security but passive reactions to china s macroeconomic reform this explains why china did not improve its energy security situation despite 30 years of reform

from nonrenewable to renewable energy and its impact on economic growth the role of research development expenditures in asia pacific economic cooperation countries abstract this study disaggregates energy i e non renewable and renewable energy consumption and investigates its effect on economic growth the period of 1990 2015 is used to examine asia pacific economic cooperation apec countries this paper determines the cross sectional dependence and employs a second generation panel unit root test for precise estimation westerlund cointegration test is used to examine the long run equilibrium relationship between the variables and confirm the presence of cointegration in the long run the continuously updated fully modified ordinary least square cup fm approaches are applied to investigate long term output elasticities between the variables the results show the stimulating role of energy renewable and nonrenewable consumption in economic growth research and development expenditures and trade openness have a positive effect on economic growth moreover the time series individual country analysis also confirms that renewable energy has a positive impact on economic growth the heterogenous causality analysis reveals the feedback effect i e bidirectional causal associations among economic growth renewable energy consumption and nonrenewable energy consumption this empirical evidence suggests that countries should increase investment in renewable energy sectors and plan for development in renewable energy for sustainable energy growth

a model of exchange rate dynamics this model treats the exchange rate as an asset price that depends on expectations concerning exogenous real and monetary factors that will affect relative prices and absolute price levels in future periods changes in exchange rates reflect both expected changes in these exogenous factors and changes in expectations occasioned by new information the model explains the random component in exchange rate behavior the source of divergences from purchasing power parity the anticipatory response of exchange rates to future expected disturbances and the causes of exchange rate overshooting

status the distribution of wealth private and social attitudes to risk this paper supposes an individual cares about his her own wealth not only directly but also via the relative standing that this wealth induces the implications for risk taking are investigated in particular such a model provides a natural explanation of the concave convex concave utility described by friedman and savage however there are a number of key differences between the present model and any model based on own wealth alone for example an equilibrium wealth distribution here may have a middle class further the status interaction involves an externality and an equilibrium wealth distribution may be pareto inefficient but also about the implied relative standing in the distribution of wealth has a long but checkered history an early exponent of such ideas was of course veblen 1899 it is indeed a notion which most economists reject albeit usually without explicit comment a notable and articulate exception however is frank 1985 for example see also the references frank cites on pp 33 34 it is however a notion with substantial intuitive appeal and it seems useful to ascertain its consequences before coming to a final judgement as to its merits the present paper is concerned with deriving the consequences of such valuation of status for risk taking what seems to be the sharpest possible model is adopted here this assumes that what is essentially ordinal rank in the wealth distribution enters von neumann morgenstern utility as an argument in addi tion to wealth itself thus higher wealth increases utility not only directly but also indirectly via higher status in the interests of both simplicity and drama it is typically assumed here that all individuals have identical utility functions which are concave in wealth but convex in status section 2 discusses how the model provides a natural explanation of the fundamental phenomenon addressed by friedman and savage 1948 that individuals may simultaneously purchase insurance and participate in lotteries although each individual here has a utility function which is concave in wealth itself utility can nevertheless be convex in wealth over some range when the indirect effect via status is included this effect is enhanced by the convexity of utility in status but will follow in any case if increasing wealth entails moving up in status much more rapidly than losing wealth entails moving down it is shown

social organization in an endogenous growth model we develop an endogenous growth model in which individuals form matches in order to consume goods that are not explicitly traded the matching process endogenously generates a concern for relative wealth and is thereby beneficial for capital accumulation and economic growth we then study how social segmentation in the matching process affects economic growth under strong segmentation social competition over mates occurs inside homogeneous groups this homogeneity increases the severity of the rat race of wealth accumulation and fosters economic growth

capturing the impact of shocks on the electricity sector performance in the oecd abstract this paper focuses on the responses of electricity performance to shocks arising from structural reform policies with a dynamic panel vector autoregression pvar model that allows endogeneity we decompose the responses of electricity performance measures to shocks generated by the inclusion of structural reform indicators capturing the effect of competition regulation and privatization the sample spans the period from 1975 to 2011 including 30 oecd countries the empirical findings do confirm that a robust independent regulatory scheme must be implemented in order to achieve a competitive electricity market finally the dynamic pvar results using impulse response functions and variance decomposition analysis further support the validity of these results

exchange rate discounting abstract economists often describe nominal exchange rates as forward looking so that they reflect discounted expected future fundamentals this study applies a method for identifying the discount rate involved without knowing or measuring fundamentals identification arises from assumptions on the stochastic process followed by fundamentals combined with non linearity arising from expected future regime changes two applications yield evidence against the present value model in the form of discount rates which are negative and statistically significant

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

reputation concerned policy makers and institutional status quo bias abstract we study the policy choice of an office holding politician who is concerned with the public s perception of his capabilities the politician decides whether to maintain the status quo or to conduct a risky reform the reform s success depends critically on the politician s capabilities which are privately known to the politician the public observes both his policy choice and the outcome of the reform and assesses his competence we show that the politician may engage in socially detrimental reform in order to be perceived as more capable we investigate the institutional remedy that balances the gains and costs when the policy maker is subject to reputation concerns conservative institutions that thwart beneficial reform may potentially improve social welfare
