parents discount rates for child quality contemporary discussions of economic growth make human capital or knowledge accumulation its primary engine 25 human capital as the lead component of the stock of wealth defines a developed economy becker and murphy 4 show that human capital both increases and is increased by the scope of the market its rate of return rises with the size of its stock 5 human capital also plays significant roles in models of human fertility choice 40 population and environmental degradation 11 34 capital mobility 3 and endogenous technological progress 33 a substantial portion of an adult s human capital is accumulated during childhood children as children however cannot independently contract for the resources required to support investments in this human capital though nearly every society grants parents wide discretion about the nurture they provide their children little is understood about what motivates investment by one generation in another the relative importance of different investment modes or the discount rates which parents apply whatever the motivation and the mode because of the long time span between birth and adulthood parents discount rates potentially exert great leverage upon the investment decisions they make for their children knowledge of these discount rates is a prerequisite to acquiring an improved understanding of the internal decision processes of the household a collective decision unit which economics mostly treats as a black box 1 important policy questions as well as scientific accuracy and logical consistency demand knowledge of the discount rates parents apply to investments in their children healthier better educated and wealthier children have a better chance in life but there is no evident reason to suppose that intrafamily discount rates are socially optimal 2 many of the private reactions and behaviors which reinforce or temper the intended effects of public policies are internal to the household when these intended effects have a substantial temporal dimension parental discount rates will be influential for example increased public investments in children can be neutralized

examining the link between energy consumption carbon dioxide emission and economic growth in latin america and the caribbean abstract this study aims at exploring the bi directional long run relationship between energy consumption carbon dioxide emission and economic growth in the latin american and caribbean countries the canonical cointegrating regression ccr is used to achieve the goal of this study taking the period of 1980 2008 the study arrived at different results while 60 of the countries have a positive bi directional long run relationship between energy consumption carbon dioxide emission and economic growth the others have mixed results the results of the study motivated the researcher to recommend that these countries should increase their energy efficiency increase the share of green energy from their total energy use and increase energy conservation in order to reduce unnecessary waste of energy

globalisation institutional structures and real estate markets in central european cities this paper examines the urban development process in post socialist cities of budapest prague and warsaw in the context of economic globalisation and societal transformation several factors have helped to shape the post socialist cities of central europe since the end of the 1980s these include political transformation economic change restitution privatisation price liberalisation and decentralisation of local government it is argued that local government administrative and planning structures have been ill prepared in meeting the requirements of international investment capital in a co ordinated and effective manner institutional constraints has promoted an organic form of urban development primarily determined through the international demand for and supply of commercial and retail space

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

the economy of an agglomeration the case of london the development of london over the last 30 years is discussed in the context of chinitz s seminal paper on major us agglomerations the optimism originally voiced in the 1960s over the future of major urban agglomerations has not been borne out by experience for a variety of reasons some purely economic and some the outcome of policy even relative to comparable major european cities london did worse than would be expected given its industrial structure the location of offices bureau and office development permits have been discussed as a source of decentralisation of employment but in fact had only limited effects the reversal of the long decline in central london employment shown up in the early 1980s by the cordon counts was to some degree a rearrangement of commuting patterns and had in any case faltered by the late 1980s the operation of the british land use planning system in constraining development in the south east may also have discouraged firms from expanding in london this factor may

energy consumption and economic growth revisited does the size of unrecorded economy matter abstract we analyze the long run relationship between energy consumption and real gross domestic product gdp in turkey taking into account the size of unrecorded economy since in developing countries mainly due to the unrecorded economic activities the official gdp is not measured correctly the investigation of the linkage between energy consumption and official gdp may not give reliable results in this study empirical results for the case of turkey over the period 1970 2005 suggest that there is a long run equilibrium relationship between the officially calculated gdp and energy consumption besides using the error correction modeling technique we find out that unidirectional causality runs from official gdp to energy in both short and long runs however when we take into account unrecorded economy we detect neither cointegration nor causality between energy consumption and true gdp these empirical findings imply that first energy conservation policies can be implemented in order to reduce greenhouse gas emissions without any adverse effect on the recorded economic activities second the production function in the unrecorded economy is not stable furthermore economic policies to combat unrecorded economy may not serve as a complement to energy conservation policies

problems of urban decline and growth in eec countries or measuring degrees of elephantness the purpose of this paper is to draw together several strands of literature concerned with the measurement of spatial economic and social differences and then suggest an alternative approach we then apply that approach to classifying the problems of 103 of the largest metropolitan regions in the eec countries in the process this allows us to conceptualise and attempt to quantify urban decline in europe and simultaneously discover the extent to which urban problems in europe are still associated with growth although it is hoped that the paper is infused with some theoretical and analytical insight it is primarily empirical in scope it draws on a small part of a much wider project some of the analytical support particularly the arguments and evidence that support the use of functional urban regions furs as units of analysis and all of the analytical and policy implications are reported on elsewhere 1

conceptual framework for regional competitiveness budd l and hirmis a k 2004 conceptual framework for regional competitiveness regional studies38 1007 1020 the concept of territorial competitiveness has gained ground in academic policy and practitioner circles in particular urban competitiveness has generated a large literature however there is a danger that competitiveness at a territorial level becomes a conceptual chimera the essential problem is that territorially based actors and agencies seek to position and maintain the utility of their regions and subregions by reference to a set of measures and indicators that are conceptually suspect and often empirically weak the degree to which regions compete depends on a manifold set of factors the paper proposes a conceptual framework for regional competitiveness based on combining the competitive advantage of firms and the comparative advantage of a regional economy the conceptual transmission mechanism to regional competitiveness combines liebenstein s theory of x inefficiency and aggl

electricity consumption real gdp causality nexus evidence from a bootstrapped causality test for 30 oecd countries the goal of this paper is to examine any causal effects between electricity consumption and real gdp for 30 oecd countries we use a bootstrapped causality testing approach and unravel evidence in favour of electricity consumption causing real gdp in australia iceland italy the slovak republic the czech republic korea portugal and the uk the implication is that electricity conservation policies will negatively impact real gdp in these countries however for the rest of the 22 countries our findings suggest that electricity conversation policies will not affect real gdp

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

why do schooling returns differ screening private schools and labor markets in the philippines and thailand abstract this article examines returns to schooling in the philippines and thailand using recent employee surveys in manufacturing industries empirical results show that i schooling returns steadily increase as education attainment increases in thailand but the returns increase only at university level in the philippines and that ii private school premiums are higher in the philippines than thailand the latter finding is consistent with the dominance of private institutions in the philippine education system the premiums from private schooling investments in the philippines are however found to be spurious in the sense that private schools screen high ability students which augments wage therefore the productivity gain from private schooling is small

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

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

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

a defense of compulsive measures against child labor abstract this research characterizes policies likely to trigger the onset of a growth enhancing fertility transition even for an economy with initially a low per capita income the environment considered is one where children s time has an economic value and schooling and child labor are the main competing claims on a child s time using a one parent family overlapping generations model i argue that compulsive measures against child labor are justifiable as an integral part of an intervention that combines incentives and regulations in order to eliminate child labor the analysis highlights fertility and child labor dynamics as shaped by the relative cost of children

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

economic growth and energy consumption causal nexus viewed through a bootstrap rolling window one puzzling results in the literature on energy consumption economic growth causality is the variability of results particularly across sample periods sample sizes and model specification in order overcome these issues this paper analyzes the causal links between energy consumption and economic growth for g 7 countries using bootstrap granger non causality tests with fixed size rolling subsamples the data used includes annual total energy consumption and real gross domestic product gdp series from 1960 to 2006 for g 7 countries excluding germany for which the sample period starts from 1971 using the full sample bootstrap granger causality test we find that there is predictive power from energy consumption to economic growth only for canada however parameter instability tests show that none of the estimated models have constant parameters and hence the full sample results are not reliable analogous to the full sample results the results obtained from the bootstrap rolling window estimation indicate no consistent causal links between energy consumption and economic growth we however find that causal links are present between the series in various subsamples furthermore these subsample periods correspond to significant economic events indicating that the findings are not statistical artefacts but correspond to real economic changes our results encompass previous findings and offer an explanation to varying findings

residential electricity demand dynamics in turkey abstract this article provides fresh empirical evidences for the income and price elasticies of the residential energy demand both in the short run and long run for turkey over the period 1968 2005 using the bounds testing procedure to cointegration the computed elasticities of income and price are consistent with the previous studies and as expected the long run elasticities are greater than the short run elasticities an augmented form of granger causality analysis is implemented among residential electricity income price and urbanization in the long run causality runs interactively through the error correction term from income price and urbanization to residential energy but the short run causality tests are inconclusive the parameter stability of the short run as well as long run coefficients in the residential energy demand function are tested the results of these tests display a stable pattern

educational subsidy agricultural development and fertility change in this paper the effects of continuing agricultural technical change on the allocation of resources by households between increments to family size and to schooling are examined within the context of a model of household decision making in which education facilitates innovation an empirical application of the model to data from india indicates consistent with the theory that in farm households more intensively exposed to the new technologies associated with the green revolution fertility was significantly reduced while the level of schooling investment was significantly increased in contrast and also consistent with the model proximity of schools in the absence of technical change had only marginal effects on schooling and little impact on family size

global population growth technology and malthusian constraints a quantitative growth theoretic perspective we structurally estimate a two sector schumpeterian growth model with endogenous population and finite land reserves to study the long run evolution of global population technological progress and the demand for food the estimated model closely replicates trajectories for world population gdp sectoral productivity growth and crop land area from 1960 to 2010 projections from 2010 onwards show a slowdown of technological progress and because it is a key determinant of fertility costs significant population growth by 2100 global population reaches 12 4 billion and agricultural production doubles but the land constraint does not bind because of capital investment and technological progress

growth and decline of european cities changing positions of cities in europe the paper reviews the various models of the core or cores of urban europe seeking a causal explanation for regional economic shifts the paper uses data on the location of major corporate headquarters offices an analysis of the 500 largest companies shows a concentration in london and paris in 1973 which intensifies in the period 1973 88 this period also sees significant growth in southern europe although not necessarily in the second mediterranean banana the most significant losers in 1973 88 were the ruhr and the randstad in terms of the urban hierarchy corporate office growth is strongly concentrated in paris and london and the study offers no evidence of a comparative advantage for smaller cities

motivations to remit evidence from botswana in this article a theory of motivations to send remittances is described and tested with data from botswana altruism is one of the motivations tested and found to be an insufficient explanation for remittances among migrants in botswana a refinement of the model stipulates a modified altruism or enlightened self interest in this model the relationship between the migrant and family is tempered by an implicit understanding of mutual benefit the household strategy may be to encourage some members to migrate as a means of spreading risk and sharing gains the household strategy is similar to an insurance policy where migration is to places where market potential is high the risks incurred might be high the example is given of migration during a drought in botswana migrant remittances were greater in households with more cattle or households with more to lose drought alone was not statistically related to remittances increases in remittances were related to increased levels of education it is suggested that repayment was the motive for parents investment in migrants education migrants gains are identified as the potential for an inheritance the security of channeling investments through a trusted family member and security in having a home to return to it is pointed out that the altruism and family remittances from urban migration were strategies that bridged the simple dynamic of either urban development or rural development impacting on family welfare it is suggested that household models of economy adopt some measure to express the relationship of household wealth to remittances from urban migrants

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

an intergenerational model of population growth the problem of population growth has been only partially formulated in an intertemporal context therefore a link between population theory and economic growth theory is still missing this paper attempts to provide such a link by analyzing an intergenerational model of optimum population growth the model accommodates the idea that decisions on increases in population should consider the new population s quality of life this concept is elaborated upon in a static framework by gary becker and gregg lewis dennis de tray and robert willis other literature on population growth such as harold votey disregards this consideration altogether 2 more explicitly this paper assumes that the utility of each generation is a function of the level of its consumption and the number and utility of the newly born people we are thus led to consider the utility of an infinite number of generations this model differs from paul samuelson s intergenerational model of pure consumption in which the utility of each generation depends only on that generation s own consumption recently philip neher 1971 analyzed a model of fertility in primitive economies it is based on the assumption that parents use children as investments to insure future consumption needs neher s analysis focuses entirely on the pension motive for having children 3 our model assumes that fertility is determined so as to balance the parents welfare derived from additional children against that derived from the children s quality of life we first outline a general model of optimum population growth in order to discuss explicitly various economic aspects of population we use a simple case in the analysis section i sets up the basic model

child labor and coordination failures abstract in this note we show that a technology based coordination failure may explain the emergence of laws restricting child labor child labor may arise because of the lack of a coordination mechanism between parental decisions to invest in the human capital of their children and firms decisions to invest in skill biased technologies legislative intervention in many cases helps coordinate expectations towards a pareto superior outcome with investments both in human capital and in skill biased technologies

an estimable dynamic stochastic model of fertility and child mortality this paper develops a finite horizon dynamic stochastic model of discrete choice with respect to life cycle fertility within an environment where infant survival is uncertain the model yields implications for the number timing and spacing of children a tractable estimation method is developed for the linear constraint quadratic utility case that is intimately tied to the dynamic optimization problem and the method is applied to malaysian household data estimation is based on integrating the numerical solution of the dynamic programming model of behavior with a maximum likelihood procedure

territorial competition and globalisation scylla and charybdis of european cities policy makers in europe have been concerned with developing and sustaining the competitiveness of their cities this concern comes from the view that the determing parameter of urban regions is globalisation by engaging in a process of territorial competition the economic and social welfare of cities constituent territories can be maintained what this paper argues is that there is a danger that territorial competition is as much an abstraction as globalisation and its application to policy making will bring about distortions in economic development by examining the specification of globalisation and territorial competition and the relevant literature a debate may be initiated in which the consequences for the economic environment of european cities are addressed the discussion is given some context by drawing on the cursory examples one global and one local of london and lille

the causality between energy consumption and economic growth in turkey abstract this paper applies the causality test to examine the causal relationship between primary energy consumption ec and real gross national product gnp for turkey during 1970 2006 we employ unit root tests the augmented dickey fuller adf and the philips perron pp johansen cointegration test and pair wise granger causality test to examine relation between ec and gnp our empirical results indicate that the two series are found to be non stationary however first differences of these series lead to stationarity further the results indicate that ec and gnp are cointegrated and there is bidirectional causality running from ec to gnp and vice versa this means that an increase in ec directly affects economic growth and that economic growth also stimulates further ec this bidirectional causality relationship between ec and gnp determined for turkey at 1970 2006 period is in accordance with the ones in literature reported for similar countries consequently we conclude that energy is a limiting factor to economic growth in turkey and hence shocks to energy supply will have a negative impact on economic growth

bootstrap inference in econometrics the astonishing increase in computer performance over the past two decades has made it possible for economists to base many statistical inferences on simulated or bootstrap distributions rather than on distributions obtained from asymptotic theory in this paper i review some of the basic ideas of bootstrap inference the paper discusses monte carlo tests several types of bootstrap test and bootstrap confidence intervals although bootstrapping often works well it does not do so in every case

suicide bombing as inter generational investment a simple model of terrorism is presented where the current generation is linked to the next one by some altruism as in standard dynastic family models bombing today some target increases the probability of the benefit of some public good accruing to the next generation the model is used to discuss the fact that suicide bombers of the hezbollah in particular have been found by krueger and maleckova 2002 to come disproportionately from wealthy families and have an above average education level while the latter could be expected to increase the opportunity cost of investing in such a suicide it is suggested that it probably increases also the sensitivity to the future generation s welfare the latter effect might offset the deterrent effect of the former

electricity consumption and economic growth evidence from turkey abstract this study investigates the causal relationship between electricity consumption and real gdp in turkey during the period of 1950 2000 both of the series were found to be a stationary process around a structural break by the zivot and andrews test thus two different methodologies have been employed to test the granger non causality the dolado lutkepohl test using the vars in levels and the standard granger causality test using the detrended data both tests have yielded a strong evidence for unidirectional causality running from the electricity consumption to the income this implies that the supply of electricity is vitally important to meet the growing electricity consumption hence to sustain the economic growth in turkey

how many times again will we examine the energy income nexus using a limited range of traditional econometric tools during the last three decades following closely the developments in econometric theory energy and environmental economists have empirically examined the energy income nexus for different countries and time periods however today in spite of the growing interest in this area the state of knowledge is still controversial and unsettled this viewpoint paper attempts to highlight some of the issues related to the existing literature on the long run relationship and causality between energy consumption and economic growth in particular it discusses how it is difficult to make policy recommendations on the basis of inconsistent and conflicting results in the published literature on the subject in order to do so the paper first illustrates the increasing trend in the number of studies published in this area providing also a brief comparison of the conventional methods used to estimate the energy income nexus it then deals with new directions and different viewpoints on the same issue

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

food for education versus school quality a comparison of policy options to reduce child labour in a model in which credit markets play a crucial role we examine two policy options for reducing child labour food for education and investment in education quality with an imperfectly elastic supply of credit an increase in food subsidy is more eective in reducing child labour than an income equivalent increase in expenditures in education quality the eectiveness of the latter policy improves and the optimal share of resources devoted to this policy increases at the expense of food subsidies as the supply of credit becomes more elastic

social learning neighborhood effects and investment in human capital evidence from green revolution india abstract this paper empirically identifies social learning and neighborhood effects in schooling investments in a new technology regime social learning implies that learning is most efficient when observed heterogeneity in schooling is greatest the estimates of learning investment rule from farm household panel data at the onset of the green revolution in india show that i agents learn about schooling returns from income realizations of their neighbors and ii the speed of learning is high when the variation of schooling is large thus schooling distribution of the parents generation in a community has externalities to schooling investments in children simulations show that the variations in schooling within and across communities generate variations in child enrollment rate and average household income

exploring the relationship between agricultural electricity consumption and output new evidence from turkish regional data abstract this study investigates the relationship between agricultural electricity consumption and agricultural output for a panel of 12 regions of turkey for the period 1995 2013 in order to reveal the possible heterogeneity between regions empirical analyses are conducted for the whole panel data and two sub groups within the panel data namely coastal regions and non coastal regions the results from several panel unit root tests indicate that electricity consumption and output are stationary process at their levels for overall panel and the two specific groups by using the ols with regional fixed effects this study finds that coefficient estimate of electricity consumption on output is statistically significant and positive for overall regions coastal regions and non coastal regions in addition the results from the dumitrescu hurlin granger causality test show that there is unidirectional causality running from agricultural output to electricity consumption for non coastal regions and there is bidirectional causality between agricultural electricity consumption and output for overall panel and coastal regions findings and policy implications are further discussed

estimating a household production function heterogeneity the demand for health inputs and their effects on birth weight the household production literature emphasizes that technical or biological processes condition input selection by households in their production activities along with prices and income exogenous variations in health to the extent that they are perceived by individuals heterogeneity lead to correlations between inputs and health outcomes that cannot be used to derive causal conclusions therefore estimates of health technology must be obtained from a behavioral model in which health inputs are themselves choices consistent estimates are reported of the effect of endogenous inputs such as medical care smoking and fertility on birth weight and fetal growth in the presence of health heterogeneity

sectoral energy consumption by source and economic growth in turkey this paper provides a detailed analysis of the energy consumption in turkey during the last 40 years it investigates the causal relationships between income and energy consumption in two ways first the relationship is studied at the aggregate level then we focus on the industrial sector previous findings suggest that in the case of turkey there is a unidirectional causality running from energy consumption to growth however our findings suggest that in the long run income and energy consumption appear to be neutral with respect to each other both at the aggregate and at the industrial level we also find a strong evidence of instantaneous causality which means that contemporaneous values of energy consumption and income are correlated furthermore a descriptive analysis is conducted in order to reveal the differences in the use of energy resources we conclude that energy conservation policies are necessary for environmental concerns and our empirical results imply that such policies would not impede economic growth in the long term

endogenous fertility and optimal population size pareto optimality which is the standard criterion of efficiency in general equilibrium models takes population size as given and therefore cannot be directly applied to analyze the question of optimal population size the criterion then for optimal population size must be based on a more restrictive definition of optimality this paper extends peter diamonds 1965 golden golden rule growth model by assuming that individuals derive utility from their own consumptionand from their own children offspring are assumed to consume resources before reaching adulthood the authors show that the optimal steady state utility yields a higher population growth rate when it converges to the golden rule allocation they then demonstrate that a voluntary social security program in which the size of the transfer to a particular agent is directly tied to his own fertility leads the competitive allocation to be identical to the allocation corresponding to the maximum of the steady state utility of the representative individual

changing world prices women s wages and the fertility transition sweden 1860 1910 this time series analysis examines during 1860 1910 the impact of changes in local prices of agricultural commodities on wages among men and women in sweden and the impact of changes in wages on fertility decline child mortality urbanization and improved social conditions linear ordinary least squares models are set up to determine whether demand induced increases in womens wages relative to mens are significant factors in explaining swedish total fertility rates data are obtained from 25 counties and the city of stockholm among pooled observations for six time periods during 1860 64 and 1910 14 this period is marked by a total fertility decline of 28 a marital fertility decline of 26 and a child mortality decline of 52 explanatory variables are the relative prices of main agricultural outputs employment outside of agriculture the proportion of urban population and the child mortality rate findings indicate a significant relationship between child mortality and total fertility and specific fertility rates among women aged 20 39 years a doubling of the male real wage rate was significantly associated with earlier marriage higher birth rates among women aged 15 29 years and lower birth rates among women aged 35 49 years the ratio of male wages to female wages was associated with a decline in birth rates at all ages with the exception of teenagers 66 of fertility increase was due to declines in child mortality but this increase was counterbalanced by fertility decline among older women child mortality and urbanization depressed marital fertility male wages increased the proportion married a 10 increase in the male female wage rate was associated with a 25 reduction in the total fertility rate another 25 increase in the male female wage rate was associated with a 50 reduction in child mortality it is concluded that the value of womens time had a key impact on the swedish fertility transition

structural break unit root and the causality between energy consumption and gdp in turkey abstract this paper tries to investigate a series of unit root and causality tests to detect causality between the gdp and energy consumption in turkey employing hsiao s version of granger causality method for the 1950 2000 period the conventional unit root tests indicate the series are i 1 whereas the endogenous break unit root tests proposed by zivot and andrews zivot e and andrews d w k 1992 further evidence on the great crash the oil price shock and the unit root hypothesis journal of business and economics statistics 10 251 270 and perron perron p 1997 further evidence on breaking trend functions in macroeconomic variables journal of econometrics 80 355 385 reveal that the series are trend stationary with a structural break therefore it is inappropriate to take the first difference of the data to achieve stationarity the main conclusion of this study is that there is no evidence of causality between energy consumption and gdp in turkey based on the detrended data

population growth and human capital investments theory and evidence this paper presents evidence from empirical studies that test hypotheses derived from models of household behavior pertaining to the interrelationships among population growth human capital and economic development these studies have exploited quasi natural experiments embodied in the cross area variability in the wage rates of children in a number of low income countries the intercouple variation in the biological propensity to conceive and the geographically selective introduction of new high yielding seed varieties in india in the period 1961 71 the different varieties of evidence support the hypotheses that alterations in the returns to human capital associated with exogenous technical change lead simultaneously to increases in human capital investments and to reductions in fertility and that the costliness of fertility control is a significant but modest factor in inhibiting human capital investments

the impact of exogenous child mortality on fertility a waiting time regression with dynamic regressors in this paper the authors develop and implement an econometric methodology estimating a family specific exogenous component of life expectancy in order to determine the responsiveness of fertility to exogenous changes in child mortality they use a generalized waiting time regression model applied to length of life which is viewed as the output of a production process they allow for family specific heterogeneity in duration of life and for time varying explanatory variables the heterogeneity component retrieved from the production function estimation is used to estimate the impact of exogenous child mortality on a measure of fertility the data concern 1938 children from 311 families included in the 1976 malaysian family life survey this paper was previously published in econometrica chicago ill vol 51 no 3 may 1983 pp 731 49 excerpt

energy consumption and gdp in turkey is there a co integration relationship energy consumption and gdp are expected to grow by 5 9 and 7 annually until 2025 in turkey this paper tries to unfold the linkage between energy consumption and gdp by undertaking a co integration analysis for turkey with annual data over the period 1970 2003 the analysis shows that energy consumption and gdp are co integrated this means that there is a possibly bi directional causality relationship between the two we establish that there is a unidirectional causality running from gdp to energy consumption indicating that energy saving would not harm economic growth in turkey in addition we find that energy consumption keeps on growing as long as the economy grows in turkey

child mortality child labour and economic development the paper presents a model where the interplay between fertility child labour and education can explain economic stagnation when parents live in an environment of high child mortality if in contrast child mortality is low the solution of the parental decision problem leads to perpetual economic growth the two long run states are connected by a path of demographic transition and economic take off along which the incidence of child labour disappears the paper also discusses alternative policies to escape from the low income equilibrium
