do non socially responsible companies achieve legitimacy through socially responsible actions the mediating effect of innovation this study investigates the effects on organization s financial performances of first the extent to which the organizations are involved in controversial business activities and second their level of social performance these companies can be considered non socially responsible given the harmful nature of the activities they are involved in managers of these companies may still have incentives to pursue socially responsible actions if they believe that engaging on those actions will help them to achieve legitimacy and improve investors perception about them we develop a comprehensive methodology to investigate these corporate social performance csp related effects in a complex but specific setting to this end we analyze a sample of 202 us firms for the period 2005 2008 using a novel method in this area partial least squares our results indicate that contrary to the general findings in prior literature companies involved in controversial business activities which engage in csp do not directly reduce the negative perception that stakeholders have about them instead we found evidence of a positive mediation effect of csp on financial market based performance through innovation

the environment and emerging development issues development economics for the most part has failed to recognize renewable environmental resources as economic goods yet the lives of the poor in developing countries are intimately tied to the fate of their local common property resources soil fuel wood water and so on ignoring the loss of common property renewable resources via degradation centralization or privatization in calculations of net national product can mask the destruction of resources available to a country s poor behind the false appearance of a growing national economy this paper describes the difference between the problem of managing local common property resources in developing countries and the problem of protecting the global commons such as the atmosphere and oceans it outlines the calculations that would include the local commons in the national income accounting of capital assets and argues that the interests of those most dependent on the increasingly scarce local commons will be best served by placing control in their hands while the central government provides infrastructure and educational support to control the pollution of the global commons on the other hand the paper sketches a plan in which most countries would have a high incentive to participate a global allocation of limited tradable permits to discharge defined pollutants

the gender gap fertility and growth changes in fertility have long been recognized as important correlates of economic growth with the relationship between the level of fertility and the level of income per capita being one of the strongest observable correlations in cross country data this paper examines the linkages between fertility and growth theory the structure of the model is presented in sections on production couples decision making system dynamics and steady state equilibria the first component of the model is that increases in capital per worker raise womens relative wages since capital is more complementary to womens labor input than to mens the second component is that increasing womens relative wages reduces fertility by raising the cost of children more than household income finally lower fertility raises the level of capital per worker a positive feedback loop generates demographic transition a rapid decline in fertility accompanied by accelerated output growth

public versus private investment in human capital endogenous growth and income inequality in this paper we present an overlapping generations model with heterogeneous agents in which human capital investment through formal schooling is the engine of growth we use simple functional forms for preferences technologies and income distribution to highlight the distinction between economies with public education and those with private education we find that income inequality declines more quickly under public education on the other hand private education yields greater per capita incomes unless the initial income inequality is sufficiently high we also find that societies will choose public education if a majority of agents have incomes below average

agricultural household models extensions applications and policy this book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far the model assumes that households are price takers and is therefore recursive the decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor comparative results on selected elasticities are presented for a number of economies the empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive the book summarizes the implications of agricultural pricing policy for the welfare of farm households marketed surplus the demand for nonagricultural goods and services the rural labor market budget revenues and foreign exchange earnings in addition it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition nutritional status health saving and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings methodological topics primarily the data requirements of the basic model and its extensions along with aggregation market interaction uncertainty and market imperfections are discussed the most important methodological issues the question of the recursive property of these models is also discussed

the economics of development a survey i the subject our definition of the subject will be the use of economic analysis to understand the economies of poor or developing countries this includes in particular how standards of living in the population are determined and how they change over time and further how policy can or should be used in the influence of these processes the definition contains in principle much or most of analytical methods in economics insofar as they can be put to use in the examination of the issues of interest this is as it should be but it poses a problem for a survey in a journal a comprehensive treatment is infeasible so we shall follow a different route the survey will focus on what i take to be the major themes and approaches which characterise the productive aspects of the subject there is therefore no pretence at being exhaustive the purpose is rather to highlight some of the advances many of these have been of real substance there are a number of possible purposes for a survey and it is important to be clear at the outset for whom it is intended what it is and what it is not this survey is addressed to economists and students of economics who know the tools of their trade but not necessarily how they have been applied to and fashioned for the analysis of the economics of developing countries it is a description of the ways in which problems can be productively formulated and approached in terms of examples chosen for their intrinsic importance and interest the vastness of the subject means that we have to be highly selective it does not seek to provide a summary evaluation of the current view of the appropriate response to immediate policy questions it is not a history of thought nor a research manifesto nor an attempt to adjudicate or settle the major debates where they arise naturally from the major purpose some judgements on these subjects will be offered but they do not themselves constitute the primary intent of this survey there are three lines of enquiry or sets of questions which have i suggest been distinctive of the most fruitful work in development economics they will

nonoptimality of the friedman rule with capital income taxation this paper studies the efficient taxation of money and factor income in intertemporal optimizing growth models with infinite horizons transaction costs technologies and flexible prices second best optimality calls for a positive inflation tax and a non zero capital income tax when there are restrictions on taxation of production factors or profits rents our cases of nonoptimality of the friedman rule which differ from those of mulligan and sala i martin 1997 and extend substantially those of schmitt grohe and uribe 2004a follow from the violation of the diamond and mirrlees 1971 principle on production efficiency

fertility volatility and growth abstract empirically growth rates are negatively correlated with birth rates they are also correlated with production risk we argue that these stylized facts are related and arise jointly from the decision of how many children to have in a risky environment

recognizing progeny in the value of life abstract this note generalizes the value of life to incorporate the preferences for descendants of a dynastically altruistic decision maker it derives the value of progeny and shows how it depends on the benthamite vs millian nature of dynastic altruism

testing the external effect of household behavior the case of the demand for children this paper tests the external effect of household childbearing behavior by drawing on microfertility data from china the test is executed by regressing one woman s fertility on the average fertility of neighboring women china s unique affirmative birth control policy provides us with quasi experimental fertility variation that facilities identification we present two identification methods 1 testing the external effect from the dominant han chinese on minority women by using the fertility fine as an instrumental variable and 2 identifying the external effect using an instrumental variable that is based on the difference in differences we find that fertility has a large external effect

shareholder value stakeholder management and social issues what s the bottom line we test the relationship between shareholder value stakeholder management and social issue participation building better relations with primary stakeholders like employees customers suppliers and communities could lead to increased shareholder wealth by helping firms develop intangible valuable assets which can be sources of competitive advantage on the other hand using corporate resources for social issues not related to primary stakeholders may not create value for shareholders we test these propositions with data from s p 500 firms and find evidence that stakeholder management leads to improved shareholder value while social issue participation is negatively associated with shareholder value copyright 2001 john wiley sons ltd

a model of longevity fertility and growth abstract economic and demographic outcomes are determined jointly in a dynamic general equilibrium model of longevity fertility and growth reproductive agents in overlapping generations mature safely through two periods of life and face an endogenous probability of surviving for a third period given this probability each agent maximises her expected lifetime utility by choosing consumption and the number of children child bearing is costly in the sense that time must be spent on child rearing activities rather than on production or education the model produces multiple development regimes which yield different predictions about life expectancy fertility timing of births and educational investment depending on initial conditions these predictions accord strongly with the empirical evidence on demography and development

evidence on the demographic transition abstract this paper finds that fertility responds to productivity differently depending on the economy s stage of development at low levels of development productivity increases will increase fertility while at the more advanced stages of development productivity increases lower fertility during the process there may be important interaction effects between productivity and education demand increases in secondary education demand generate fertility declines regardless of the stage of development

fertility decline as a coordination problem abstract the so called diffusion of innovation approach is often used in explanations of historical and contemporary fertility declines we investigate this issue by developing a new theoretical analysis which combines economic and sociological reasoning particular attention is devoted to the role of social networks for the selection of equilibria in situations when fertility decline constitutes a coordination problem we show that the effect of networks depends on the particular interaction among individuals and on the prevailing socioeconomic conditions information networks can only speed up a fertility transition that would also take place in the absence of social interaction while coordination networks can facilitate demographic change in societies that would otherwise be caught in a malthusian situation

looking at the population problem through the prism of heterogeneity welfare and policy analyses upon introducing heterogeneity and dynamics into a model of the demand for children a problem of optimal population is defined and analyzed it is shown that from the perspective of social welfare better educated individuals produce too few children while less educated individuals produce too many children and all individuals invest too little in the education of their children the impact of several policy tools geared at addressing the population problem is investigated in particular how child allowances and other tax subsidy policies can be harnessed to enhance welfare and how and why early childhood education programs can mitigate the population problem

multiple bgps in a growth model with habit persistence this paper establishes multiple balanced growth paths in an otherwise standard competitive growth model without externality or distortions and with households preference dependent upon how his her consumption compares to a habit stock formed by his her own past consumption the key feature in our model is that consumption forms habits in combination with existing habits this model establishes multiple equilibria because habit persistence induces an internal intertemporal complementarity effect among consumption flows with current consumption reinforcing future consumption as a result there exist two balanced growth paths with one path exhibiting low consumption and habits and high economic growth and the other path exhibiting high consumption and habits and low growth that is not necessarily a development trap both steady states are saddles but global indeterminacy arises where a high balanced growth path co exists with a low balanced growth path where the two equilibrium paths cannot be pareto ranked and history need not matter for the selection of the equilibrium path

is child labor inefficient we build a model of child labor and study its implications for welfare we assume that there is a trade off between child labor and the accumulation of human capital even if parents are altruistic and child labor is socially inefficient it may arise in equilibrium because parents fail to fully internalize its negative effects this occurs when bequests are zero or when capital markets are imperfect we also study the effects of a simple ban on child labor and derive conditions under which it may be pareto improving in general equilibrium we show that the implications of child labor for fertility are ambiguous

the political economy of fertility this paper studies the political economy of fertility specifically i argue that fertility may be a strategic choice for ethnic groups engaged in redistributive conflict i first present a simple conflict model where high fertility is optimal for each ethnic group if and only if the economy s ethnic diversity is high institutions are weak or both i then test the model in a cross national dataset consistent with the theory i find that economies where the product of ethnic diversity and a measure of institutional weakness is high have increased fertility rates i conclude that fertility may depend on political factors

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

a resource based perspective on corporate environmental performance and profitability drawing on the resource based view of the firm we posited that environmental performance and economic performance are positively linked and that industry growth moderates the relationship with the returns to environmental performance higher in high growth industries we tested these hypotheses with an analysis of 243 finns over two years using independently developed environmental ratings results indicate that it pays to be green and that this relationship strengthens with industry growth we conclude by highlighting the study s academic and managerial implications making special reference to the social issues in management literature

population consumption and resources ethical issues abstract this article is about the concept of optimum population and consumption even though it is primarily concerned with foundational issues the various ideas that have been discussed in the literature are tested in the context of economic models with limited resources it is argued that broadly speaking existing theories of optimum population and consumption are variants of average and what is often termed classical utilitarianism respectively both classes of theories are shown to have deficiencies in great measure because of their reliance on a defective concept of personhood it is also argued that contractual theories are of little use because potential people as opposed to future people cannot be parties to any contract a generation relative ethics is developed and is put to work in an overlapping generations model it is shown that generation relative ethics even when it is a variant of classical utilitarianism can prescribe a considerably lower population than classical utilitarianism

a strategic analysis of global warming theory and some numbers we model the global warming process as a dynamic commons game in which the players are countries their actions at each date produce emissions of greenhouse gases and the state variable is the current stock of greenhouse gases the theoretical analysis is complemented by a calibration exercise the first set of results establishes theoretically and then with illustrative numbers the over emissions due to a tragedy of the commons the power of simple sanctions to lower emissions and increase welfare is then examined as is the effect of cost asymmetry finally a complete theoretical charactrization is provided for the best equilibrium and it is shown that it has a very simple structure it involves a constant emission rate through time

singapore and the new regionalism bilateral trade linkages with japan and the us free trade areas ftas have recently become an integral part of singapore trade policy this paper discusses the reasons behind singapore s recent embracement of new regionalism with particular reference to the proposals to form ftas with japan and the us the paper goes on to examine various aspects of singapore s trade linkages with the two economic superpowers in some detail popular discussion of ftas gives one the appearance that such a trade policy is entirely benign the paper sounds a cautionary note highlighting some reasons to be concerned with singapore s recent embracement of the new regionalism

efficiency with endogenous population growth in this paper we generalize the notion of pareto e ciency to make it applicable to environments with endogenous populations two di erent e ciency concepts are proposed p e ciency and a e ciency the two concepts di er in how they treat people that are not born we show how these concepts relate to the notion of pareto e ciency when fertility is

critical survey endogenous growth theory a critical assessment a critical assessment is made of endogenous growth theory from the perspective of recent developments within economics as a discipline these include its increasing mathematical formalisation its focus upon microfoundations the casual use of econometrics to test models and the incorporation of factors that have traditionally been outside mainstream economics it is found that the theory focuses upon market imperfections and technological progress in a variety of ways and reconstructs their impact upon the macroeconomy as a growth rather than as a level effect whilst the growth rate is endogenised this leads to the problem of multiple equilibria and extremely complex dynamics the generalisation from exogenous growth theory is however associated with even more extreme assumptions and analytical distance from the socioeconomic processes of growth itself copyright 2000 by oxford university press

the population problem theory and evidence this study is concerned with the relationships among population growth poverty and environmental degradation with particular focus on the situation in developing countries the author rejects the concept of a general theory of fertility behavior in favor of an interpretation of these relationships which might be applicable to certain situations in the poorest parts of the indian subcontinent and sub saharan africa such situations include unacceptable risks of maternal death for poor illiterate women and a condemnation to extreme poverty in conditions of the deterioration of local resources and of the environment the author concludes that population growth rates are too high in certain specific areas and that an appropriate policy reaction to such conditions would be to try to change the options that men and women face so that their reasoned choice would be to lower their fertility

the economics of schooling production and efficiency in public schools n recent years public and professional interest in schools has been heightened by a spate of reports many of them critical of current school policy these policy documents have added to persistent and long standing concerns about the cost effectiveness and fairness of the current school structure and have made schooling once again a serious public issue as in the past however any renewed interest in education is likely to be short lived doomed to dissipate as frustration over the inability of policy to improve school practice sets in this frustration about school policy relates directly to knowledge about the educational production process and in turn to underlying research on schools although the educational process has been extensively researched clear policy prescriptions flowing from this research have been difficult to derive 2 there exists however a consistency to the research findings that does have an immediate application to school policy schools differ dramatically in quality

the corporate social performance content of innovation in the u k this article investigates the influence of innovation on the relationship between corporate strategy and social issues specifically we employ firm level data for a large sample of u k companies drawn from a diverse range of industrial sectors to investigate given innovation the determinants of both the probability that the innovation brings reduced environmental impacts and or improved health and safety and the strength of this effect in this connection we find evidence of a dichotomy between product and process innovations and roles for firm size industrial sector a foreign market presence access to various information sources e g universities and government research organisations and the extent to which activities are constrained by regulation furthermore we find a tendency for the influences of many of these factors to vary between older and newer firms

school attendance and child labor a model of collective behavior this paper theoretically investigates how community approval or disap proval aects school attendance and child labor and how aggregate behavior of the community feeds back towards the formation and persistence of an anti or pro schooling norm the proposed community model continues to take aggregate and idiosyncratic poverty into account as an important driver of low school attendance and child labor but it provides also an explanation for why equally poor villages or regions can display dierent attitudes towards schooling distinguishing between three dierent modes of child time allocation school attendance work and leisure the paper shows how the time costs of schooling and child labor productivity con tribute to the existence of a locally stable anti schooling norm it proposes policies that eectively exploit the social dynamics and initiate a permanent escape from the anti schooling equilibrium an extension of the model explores how an education contingent subsidy paid to the poorest families of a community manages to initiate a bandwagon eect towards education for all the optimal mechanism design of

trade policy reforms and the structure of protection in vietnam this paper examines the current state of the trade policy regime in vietnam against the backdrop of market oriented policy reforms undertaken over the past one and a half decades the core of the paper is an in depth analysis of the structure of protection focusing on both incentives for import competing production and the bias in the incentive structure against export production compared to import competing production it is found that despite notable reform efforts the structure of protection in vietnam is still out of line with that of the major trading nations in the region in terms of the level and the inter industry dispersion of nominal and effective protection rates there is a clear anti export bias in the incentive structure even though the degree of the bias has considerably declined over the years there is no evidence to justify the existing protection structure on grounds of infant industry protection or employment generation

strategic choices in polygamous households theory and evidence from senegal this paper proposes a strategic framework to account for fertility choices in polygamous households a theoretical model specifies the main drivers of fertility in the african context and describes how the fertility of one wife might impact the behavior of her co wives it generates predictions to test for strategic interactions exploiting original data from a household survey and the demographic and health surveys in senegal empirical tests show that children are strategic complements one wife raises her fertility in response to an increase by the other wife because children are the best claim to resources controlled by the husband this result is the first quantitative evidence of a reproductive rivalry between co wives it suggests that the sustained high level of fertility in africa does not merely reect women s lack of control over births as is often argued but also their incentives to have many children this paper also contributes to the literature on household behavior as one of the few attempts to open the black box of non nuclear families

fertility choice and economic growth theory and evidence this proposed theoretical model is based on new models of barro and becker and becker murphy and tamura and explains the interaction of family decisions about fertility and the macroeconomy in a growth situation the proposed model captures a dynamic interaction between labor leisure and fertility choice and a structural fertility preference shock endogenous factor are consumption labor leisure and fertility while exogenous factors are production and utility parameters the aim was to develop a general equilibrium model which expresses short and long term dynamics to test the impact of economic disturbances on fertility and to explain the us baby boom and subsequent fertility patterns savings in capital accumulation and in labor supply were expected to have ambiguous effects while improved productivity was expected to increase steady state consumption the methodology a structural vector auto regression var model was developed by blanchard and quah and ihmed ickes wang and yoo structural impacts include disturbances in employment fertility theoretical preference shift and output long term restrictions are based on theory rather than on ad hoc causal orderings sims method or current responses bernanke method the structural var model is estimated using the logged differences of labor fertility rate and output the empirical results are based on analysis of us data 1949 88 on fertility weekly hours worked and real gross national product the model revealed that fertility choice should not be considered exogenous to the labor market or to economic growth variance of the forecast error for the fertility rate was significantly explained by employment shocks the effect was reduced fertility and increased labor force effort output responses to fertility and technology shocks were similar to those reported by shapiro and watson in the variance decomposition analysis output shocks explained about 33 of output variance fertility shocks explained about 33 of labor growth and 25 of output growth after the first year with a lag of one year about 37 of fertility variance was explained by employment shocks concluding remarks underscore the importance of knowing which shock initiated the motion and causal ordering

intra generational equity and sustainable welfare a time series analysis for the uk and sweden this paper discusses the importance of intra generational equity to sustainable development it outlines a number of methodologies for measuring income inequality in the economy and presents several possible ways of incorporating the impact of distributional effects into measures of welfare in the economy the authors highlight in particular an index developed by atkinson atkinson a b 1970 distributive politics and economic growth q j econ may 465 490 based on the social welfare model this method possesses two main advantages over other methods firstly it is expressed directly in terms of social well being secondly value judgements incorporated into the measure are made explicit through the parameter o which expresses society s degree of aversion to income inequality the paper calculates the value of the atkinson index for two case study countries sweden and the uk between 1950 and 1996 for a central estimate of o0 8 the results show that the welfare loss due to inequalities in the distribution of income varied between 5 and 10 for sweden and between 6 and 14 for the uk with the higher values coming towards the end of the period the paper explores the sensitivity of these results to changes in the value of o for the case of the uk and discusses the relevance of the work to the measurement of sustainable welfare 2000 elsevier science b v all rights reserved

discrete choice with social interactions this paper provides an analysis of aggregate behavioural outcomes when individual utility exhibits social interaction effects we study generalized logistic models of individual choice which incorporate terms reflecting the desire of individuals to conform to the behaviour of others in an environment of noncooperative decisionmaking laws of large numbers are generated in such environments multiplicity of equilibria in these models which are equivalent to the existence of multiple self consistent means for average choice behaviour will exist when the social interactions exceed a particular threshold local stability of these multiple equilibria is also studied the properties of the noncooperative economy are contrasted with the properties of an economy in which a social planner determines the set of individual choices finally a likelihood function based on the theoretical model is given and conditions for the econometric identifiability of the model are established

can government enforcement permanently alter fertility the case of china i introduction in developing countries per capita output growth objectives are often stymied by high birth rates 1 traditional values ignorance of birth control technology and labor intensive farming are all factors which contribute to high fertility rates for those reasons many developing countries experiencing high birth rates adopt population control policies while most programs combine educational efforts with some form of persuasion many also provide strong economic disincentives to high fertility 2 of particular interest from this vantage point is the experience of the people s republic of china which stands alone in its use of quotas on child bearing decisions 3 china s population control policy began with a massive campaign in 1953 reversing an earlier pro natalist stance however that campaign was curtailed by the political turmoil arising from the great leap forward and the cultural revolution population control programs resumed in 1970 with the issuance and enforcement of three reproductive norms late marriage longer spacing between births and fewer children in 1979 the authorities went even further allowing each household to have only one child interest in china s experience arises not only from the severity of the restrictions but also due to the government s ability to enforce them the feasibility of enforcing these restrictions is a result of the deep penetration of the communist party into most aspects of an individual s life including its control over housing employment and salaries 4 however despite the government s extensive involvement in birth planning those who study chinese demography have debated the extent to which government policies are responsible for the large fertility decline in the 1970s 5 this paper uses recent advances in economic theory and econometrics to quantitatively assess the main sources of fertility fluctuations in china specifically we employ a model with endogenous fertility choice which modifies the framework of razin and ben zion 1975 and barro and becker 1989 6 in contrast to other papers we focus on the relationship between government enforcement of population control policies and fertility outcomes we also allow the fertility rate to be affected by 1 household preferences including alterations in taste as well as in education health care and the changing role of women and 2 production technology which mostly captures changes in agricultural output or income we perform simple comparative static analysis to examine long cycles in fertility and output and characterize the transitional dynamics which govern short cycles easterlin 1968 and lee and loschky 1987 provide nice discussions of long fertility cycles the long run steady state predictions will be used to identify the empirical structural vector autoregression var system as well as interpret the underlying structural disturbances additionally the transitional dynamics results can be compared to the estimated dynamic structure finally we employ a structural var as in blanchard and quah 1989 and ahmed ickes wang and yoo 1993 to econometrically disentangle the relative contributions of policy and economic development factors to changes in fertility growth the structural disturbances include a change in the government s enforcement power a technological advance in agricultural production and a preference shift toward a higher fertility rate all of which are capable of generating both short and long cycles in fertility and output we find that government enforcement power has a significant negative effect on fertility accounting for about one third of the variance of the forecast error for fertility growth after the first year an expansion in agricultural output on the other hand yields a short run positive impact on fertility growth and is responsible for almost one fifth of fertility growth variations furthermore while theoretically all shocks have the potential to generate long cycles only preference shifts have statistically significant long run effects

malthus in the light of climate change abstract to reconsider the malthusian predictions of natural limits to economic development the paper develops a multi sector growth model with exhaustible resource extraction investments in physical and knowledge capital climate change and endogenous fertility economic growth is driven by endogenous innovations which increase in the availability and productivity of research labour poor substitution of natural resources triggers sectoral change climate change is the result of polluting resource use which is like consumption and investments based on the intertemporal optimization of the households highlighting the importance of bounded resource supply and of rational extraction decisions i show that climate change is independent of population growth in steady state and there is no causal relationship between climate and population during transition to steady state the consumption per capita growth rate rises in the innovation rate and the output elasticities of labour and capital in the different sectors unlike climate policy population policy is not warranted it may be counterproductive because labour is crucial for the research sector

the environmental impact of poverty evidence from firewood collection in rural nepal abstract we investigate determinants of household firewood collection in rural nepal using 1995 96 and 2002 3 world bank living standards measurement survey lsms data we incorporate village fixed effects endogenous censoring measurement error in living standards and heterogeneous effects of different household assets we find no evidence in favor of the poverty environment hypothesis the evidence for the environmental kuznets curve depends on the precise measure of living standards and time period studied firewood collections fall with a transition to modern occupations and rise with increasing population and household division the local interhousehold collection externality is negligible indicating that policy interventions are justified only by ecological considerations or nonlocal spillovers

does school quality matter returns to education and the characteristics of public schools in the united states this paper estimates the effects of school quality measured by the pupil teacher ratio average term length and relative teacher pay on the rate of return to education for men born between 1920 and 1949 using earnings data from the 1980 census we find that men who were educated in states with higher quality schools have a higher return to additional years of schooling rates of return are also higher for individuals from states with better educated teachers and with a higher fraction of female teachers holding constant school quality measures however we find no evidence that parental income or education affects average state level rates of return

the transfer and application of product service systems from academia to uk manufacturing firms the servicisation of many advanced economies is thought by many commentators to provide opportunities to move society away from unsustainable patterns of production and consumption the concept of the product service system pss has been conceptualised in academic circles to assist in the attainment of such desirable futures this paper reports the findings of research conducted as part of the solid project which considered the transfer and application of the pss concept from academia to industry in the united kingdom it draws upon theories from evolutionary economics to provide a rationale for the transfer of the pss concept and the role of this in achieving desirable technological change the paper also identifies an appropriate methodology to transfer the pss concept from uk academic circles to industry and the factors which impact upon and importantly lead to the successful completion of this process the combination of theoretical insight with case study research is used to develop a framework that could help uk based intermediaries to complete the transfer of the pss concept this is seen as an integral part of public policies aimed at stimulating sustainable patterns of production and consumption

the economics of poverty in poor countries this paper which examines recently studied links between 1 poverty high fertility and undernourishment and 2 environmental degradation and civic disconnection in developing countries opens by reviewing the limitations of orthodox discussions of economic institutions and property rights and the orthodox dichotomy that has located the cause of poverty in the suppression of markets the introduction also notes that much of the analysis in this paper is based on data from sub saharan africa and india the next section of the paper summarizes evidence on the magnitude and extent of world poverty section 3 exposes the connection between undernourishment and a persons capacity to work as one of the pathways to the poverty trap sections 4 and 5 consider the dependence of impoverished rural populations on common property resources and how the conventional process of economic growth can break down this system and make certain sections of the population especially vulnerable to economic shocks the next two sections explore the possibility that links between poverty high fertility and environmental degradation may constitute another pathway to the poverty trap the eighth section reviews the methodology of using net national product which includes resource depletion and environmental deterioration as an evaluation criterion and argues that mainstream development economists may have neglected environmental and population problems because they have been relying on the wrong economic indices the final section concludes that a number of policies must be used to improve options for people

the impact of r d on innovation for wind energy in denmark germany and the united kingdom this paper examines the impact of public research and development r d support on cost reducing innovation for wind turbine farms in denmark germany and the united kingdom uk first we survey the literature in this field the literature indicates that in denmark r d policy has been more successful than in germany or the uk in promoting innovation of wind turbines furthermore such studies point out that subsidy induced capacity expansions were more effective in the uk and denmark in promoting cost reducing innovation than in germany the second part of the paper describes the quantitative analysis of the impact of r d and capacity expansion on innovation this is calculated using the two factor learning curve 2flc model in which investment cost reductions are explained by cumulative capacity and the r d based knowledge stock time series data were collected for the three countries and organized as a panel data set the parameters of the 2flc model were estimated focusing on the homogeneity and heterogeneity of the parameters across countries we arrived at robust estimations of a learning by doing rate of 5 4 and a learning by searching rate of 12 6 the analysis underlines the homogeneity of the learning parameters enhancing the validity of the 2flc formulation

poverty income distribution and policy making this paper deals with the key distributional issues arising from the regulation of the environment and the management of natural resources the paper is divided into a section dealing with poverty and a section dealing with broader income distribution effects although there is much discussion of the linkages of poverty to environmental degradation empirical studies establishing these linkages are few the relationship is critically dependent on the institutional structures in the countries concerned and how they respond to changing environmental pressures on the broader distributional impacts the papers focusses on the analysis of ganiers and losers from environmental regulations the analysis is complex because the direct incidence is not the same as the final incidence much of the work has looked only at the former in addition the political economy of regulation needs to pay greater attention to impacts on key and vulnerable groups more so than can be done by looking at broad income bands

reproductive externalities and fertility behaviour abstract this article studies reproductive externalities within rural communities in poor countries it is shown that such externalities create a link between household poverty household size and the local natural resource base each of which is viewed as being endogenous the models presented here offer an explanation for the fact that in recent decades large groups of people in various parts of the world have been unable to lift themselves out of acute poverty even while their national economies have on average enjoyed economic growth implications for policy and institutional changes are drawn

beyond the quantity quality tradeoff population control policy and human capital investment abstract the quantity quality tradeoff theory implies that a reduction in fertility would induce more human capital investment per child and it is widely believed that population control policy could promote human capital levels in developing countries china s one child policy ocp has significantly reduced the fertility in the country and popular belief holds that this policy has contributed to the enhancement in china s human capital since 1979 however the quantity quality tradeoff dose not present the complete truth another crucial factor relates to which segment of the population is reduced a critical issue that has been ignored in the literature china s ocp is significantly more strictly implemented in urban areas than in rural areas where human capital investment in children is significantly lower this two tier ocp could have significantly increased the rural urban fertility ratio and brought about important consequences we first emphasize the importance of such a population compositional effect which may offset the potentially positive quantity quality tradeoff effect on human capital we present a simple analytic framework and quantify the relative sizes of the quantity quality tradeoff and compositional effects we find that the former is dominated by the latter and that the ocp has reduced the average human capital level of china s next generation by approximately 1 2 this novel evidence indicates that the conventional wisdom on population control may be incomplete and that its policy implications could be misleading

social norms savings behavior and growth we argue that many goods and decisions are not allocated or made through markets we interpret an agent s status as a ranking device that determines how well he or she fares in the nonmarket sector the existence of a nonmarket sector can endogenously generate a concern for relative position in for example the income distribution so that higher income implies higher status moreover it can naturally yield multiple equilibria it is thus possible to explain differences in growth rates across countries without recourse to differences in underlying preferences technologies or endowments different social organizations lead to different reduced form preferences which lead to different growth rates

old age pensions and fertility in rural areas of less developed countries some evidence from mexico this paper reviews the theoretical relationship between old age pensions and human fertility and offers preliminary evidence from mexico on the direction and magnitude of the effect on fertility of the introduction of a formal old age pension system the security motive is an untested but plausible hypothesis especially for rural areas where alternative methods for caring for the elderly if they exist are likely to be relatively risky and unprofitable a number of different effects can theoretically be expected following introduction of a system of old age pensions in such areas including a savings reduction effect and life cycle effects such as effects on the time phasing of labor force participation and of consumption and effects on family fragmentation and intergenerational transfers and on the sex composition of the labor force and the allocation of family resources between the sexes information costs uncertainties about various aspects of the social security system and the possibility of differences between desired and actual fertility must also be considered given the long list of possible effects and offsetting influences and uncertainties about the magnitudes of such effects the actual outcome can only be resolved empirically data on sugar cane workers who began to be covered by a social security system in 1963 in 34 contiguous rural municipalities in the papaloapan river basin in southeastern mexico were used to test the relationship a regression analysis of the determinants of change in the child woman ratios in the 34 municipalities from 1960 70 indicated among other findings that the proxy used for the influence of participation in an old age pension system had a significantly negative effect on fertility an increase in social security participation from 0 to 50 would appear to reduce the child woman ratio by more than 1 10 despite the simplicity of the testing procedure shortcomings in the available data and the possibility of specification bias the results indicate that the security motive may be important and requires further empirical and theoretical research

non convexities in continuous time investment theory that non convex preferences or technologies cause problems for economic theory is well known in recent years there have been numerous contributions to the nonconvexity problem in the context of models with a finite dimensional commodity space in the capital theory context non convexities have received explicit treatment in a few papers in two distinguishable ways the problem is cast either in a discrete time framework aoki 1971 rothschild 1971 or in a continuous time framework in which there are implicitly unbounded economies of scale in investment the latter formulation leads to jumps in the state variable or lumpy investment the standard problem treated is one of decreasing costs in the installation of new capacity contributions include chenery 1952 dixit mirrlees and stern 1975 hartwick 1976 manne 1967 srinivasan 1967 starrett 1978 and weitzman 1970 these types of analysis unfortunately ignore some of the most interesting problems associated with non convexities in investment theory in a discrete time framework the important distinction between stocks and flows is blurred while the capacity installation problem by admitting unbounded scale economies excludes the smoothing of state variables that follows by allowing for eventually increasing costs of adjustment in this paper we undertake a systematic examination of non convexities or sometimes non concavities in the context of a classic problem in continuous time investment theory the optimal accumulation of capital by a firm maximizing its present value over an infinite horizon while the results obtained are specific to this particular model we feel that they can be qualitatively extended to any capital theory problem which can be cast in a continuous time optimal control theory framework there are various sorts of non2 convexities which can arise in these problems first there can be either stock or flow non convexities that is non convexities which are introduced into the net benefit function the measure of the flow of benefits at each moment through changes in the capital stock state variable on the one hand or changes in the flow of investment control variable on the other if the benefit and transition functions are not concave in both these variables then necessary conditions are no longer sufficient for optimality and conventional marginal analysis fails non convexities can also be introduced into the value functional which has a stock dimension in order to examine these different sorts of non convexity problems we shall now present the basic economic problem a firm is faced with the problem of maximizing the present value of discounted cash flow over an infinite horizon hence it chooses an investment programme i t to maximize 00

how trade saved humanity from biological exclusion an economic theory of neanderthal extinction abstract one of the great puzzles in science concerns the rise of early modern humans and the fall of neanderthals a number of theories exist and many support the biological principle of competitive exclusion but the evidence for such mechanistic theories in which biology is destiny is limited in response this paper develops a behavioral model of neanderthal extinction we show how the endogenous division of labor and subsequent trading among early modern humans could have helped them to overcome potential biological deficiencies we discuss the relation between economics and natural selection and show how trade may partially offset natural selection

organizing contests for status the matthew effect vs the mark effect what is the best way to design tournaments for status in which individuals labor primarily for the esteem of their peers what process in other words should organizers of status based contests impose upon those who covet peer recognition we propose a formal model of status based competition that contrasts two competing alternatives the first following merton is the matthew effect according to which a tournament s architect directs slack resources to elite actors and thus widens the distribution of rewards by favoring cumulative advantage the second is the mark effect under which a tournament s designer instead pushes slack resources to marginal actors and thus tightens the distribution of rewards our results suggest that although the mark effect is better for the social welfare of most tournaments the matthew effect is preferable in two distinct contexts in small tournaments where variation in underlying ability translates into acute advantages for the most capable contestants and in large tournaments whose contestants face constant rather than rising marginal costs a condition we relate to contestants perception of their work as intrinsically valuable our contributions are twofold we find counter to the thrust of merton s work that cumulative advantage is not invariably optimal for the functioning of status contests and we identify circumstances in which the production of superstars is likely to make contests for status better off in aggregate implications for future research on status and management are discussed this paper was accepted by olav sorenson organizations and social networks

population growth and economic growth a reconsideration abstract in an endogenous growth model endogenous fertility a neo malthusian relation emerges only when all exogenous variables are controlled for this suggests that conflicting findings in the literature may originate from heterogeneity in unobserved variables in cross country panel data sets

income and the environment in rural india is there a poverty trap we study the relationships between rural income distributions and changes in environmental conditions in southern western and central india between 1994 95 and 2000 01 other than the relatively rich we find that all income strata benefit from an improved environment and intermediate expenditure households benefit more than the very poor in absolute terms higher median consumption expenditures and richness are estimated to increase environmental decline but we do not find a significant impact of income poverty on local environmental health the results do not support the poverty trap conjecture with environmental degradation driving expenditure reductions that promote offsetting aforestation which benefits the poor

south asia does preferential trade liberalisation make sense this paper systematically analyses the issue of trade liberalisation in the south asia region and offers a qualitative assessment of alternative approaches i compare two broad approaches to trade liberalisation non discriminatory and preferential the former approach can be pursued on a unilateral basis by each country in the region on a concerted basis by the countries in the region or multilateral basis under the auspices of the wto the latter approach can take the form of criss crossing bilateral free trade areas between various countries in the region or a region wide free trade area the view i take in the paper is that the move towards preferential trading is a mistake at least from the viewpoint of india india continues to have very high trade barriers so that the scope for trade diversion and the losses accompanying it are likely to be considerable business lobbies being relatively powerful in most of the countries in the region they are likely to exploit the rules of origin and sectoral exceptions in these arrangements in ways that will maximise trade diversion and minimise trade creation inasmuch as the rules of origin give bureaucrats power employment and opportunities to share in the rents created by tariff preferences they too will become active parties to the diversionary tactics of business lobbies therefore the member countries are better advised to proceed along non discriminatory lines in achieving further liberalisation

inducing innovation in the environmental technology of oligopolistic firms this paper characterizes environmental regulations which induce polluting bertrand competitors to invest efficiently in environmental r d post innovation benefits to raising rivals costs provide firms with incentives to innovate although optimal behavior cannot be elicited with pollution taxes alone an optimum can be achieved by combining emission taxes with environmental performance standards that are higher for firms which reveal superior environmental technologies faced with this policy successful innovators voluntarily reveal their technological discovery to the government despite the apparent regulatory penalty that results implications for automotive fuel regulation are discussed

population and the environment a parable of firewood and other tales the author analyzes the relationship between population and the environment with a focus on the role which environmental degradation and natural resources depletion may play in producing the population pressure which lies behind such degradation and depletion especially in developing countries the principal conclusion of this analysis is that the possibilities for a stable equilibrium between human population and its environment are quite limited i show that parental altruism toward their children can only make matters worse if socially unchecked by leading to an increase of the birthrate in every environmental state in comparison with that which would occur in its absence excerpt

nonlinearities and heterogeneity in environmental quality an empirical analysis of deforestation we use a panel data set of 59 developing countries over the 1972 1994 period to study the deforestation process relying on both parametric and semiparametric models we examine nonlinearities and heterogeneity in the deforestation process we first study the existence of an environmental kuznets curve ekc and then analyze determinants of deforestation our data sample provides no evidence of an ekc we also find that political institution failures may worsen the deforestation process in developing countries

social norms fertility and economic development abstract this paper presents an overlapping generations model with endogenous fertility and human capital accumulation within such a framework it shows how the presence of family size norms can lead to multiple equilibria it can thus potentially explain different development patterns without recourse to increasing returns and differences in initial conditions furthermore it derives sufficient conditions under which different equilibria can be pareto ranked finally it shows that the main results hold also in the case where there exists parental altruism

dynamic incentives by environmental policy instruments a survey abstract in this paper i survey and discuss recent developments on the incentives provided by environmental policy instruments for both adoption and development of advanced abatement technology a main conclusion to be drawn from the literature is that under competitive conditions market based instruments usually perform better than command and control moreover taxes may provide stronger long term incentives than tradable permits if the regulator is myopic if the government can anticipate new technology or is able to react on it optimally regulatory policies by virtue of administered prices taxes and policies by setting quantities issuing tradable permits are almost equivalent the literature also shows that under competitive conditions there is no difference between auctioning permits and grandfathering moreover timing and commitment of environmental policy is not crucial for adoption under competitive conditions commitment has positive incentive effects however if an r d sector has market power in the presence of market imperfections the ranking of the different policy instruments is ambiguous

pro poor growth and sustainable development framework evidence from two step gmm estimator abstract the environmental sustainability agenda is not easy to be achieved without implementing pro growth and pro poor growth policies across the globe pakistan s economy is no exception that strive hard to managed environmental resource capital and pro poor growth expenditures in order to reduce poverty incidence and carbon mitigation policies while many efforts need more sustainable instruments to be achieved united nation s assigned sustainable development target till 2030 the study selected an annual time series data from 1975 to 2016 and employed two step generalized method of moments gmm estimator for robust inferences the results show that higher economic growth decreases poverty incidence through social reforms while deforestation under 5 mortality rate trade openness carbon emissions and fdi inflows largely increases poverty incidence in a country the study confirmed environmental kuznets curve ekc hypothesis of carbon emissions in relation of per capita income and public spending on education while pollution haven hypothesis is confirmed due to high involvement of dirty polluting industries in country s economic transformation process the fossil fuel combustion and high population density increases carbon emissions that sabotage the process of sustainable development in a country thus it is imperative to device sustainable policies for mitigating carbon fossil emissions with cleaner production techniques and improves the quality of life of poor people through increase social expenditures that trickle down to the poor as compared to the non poor

the role of technological change for a sustainable development technological change has become a major focus in environmental policy as well as in energy and climate policy indeed there is a growing body of knowledge about how and in which direction technological change might have an impact on environmental resource constraints and how environmental policy might have an impact on this direction in this article we introduce the contributions to this special issue showing how they add to recent developments in the field of economics of technological change and sustainability we also discuss potential avenues for future research

gender inequality endogenous cultural norms and economic development this research focuses on the role played by cultural norms in the long run persistence of gender inequalities cultural norms about gender roles are considered to be endogenous and can generate gender inequality and low development traps indeed when the gender gap is internalized it leads to inegalitarian views about gender roles due to these inegalitarian beliefs boys receive more education and the initial gender gap is reinforced the existence of gender inequality traps is pointed out by the world bank as a major obstacle for economic development wdr 2006 the present article allows for a better understanding of the persistence of such traps and the means to escape

a mass phenomenon the social evolution of obesity this paper proposes a theory for the social evolution of obesity it considers a society in which individuals experience utility from consumption of food and non food the state of their health and the evaluation of their appearance by others the theory explains under which conditions poor persons are more prone to be overweight although eating is expensive and it shows how obesity occurs as a social phenomenon such that body mass continues to rise long after the initial cause e g a lower price of food is gone the paper investigates the determinants of a steady state at which the median person is overweight and how an originally lean society arrives at such a steady state extensions of the theory towards dietary choice and the possibility to exercise in order to lose weight demonstrate robustness of the basic mechanism and provide further interesting results

endogenous fertility multiple growth paths and economic convergence abstract this paper extends the cass koopmans optimal growth model to allow for endogenous fertility choice it is shown that if agents choose their fertility rate then the net rate of return on capital marginal product of capital minus the population growth rate may not be monotonically decreasing in capital in this case multiple steady states and growth paths may emerge which can explain the persistent differentials in income between poor and rich countries as well as the existence of development miracles and disasters the paper provides also empirical evidence which supports the existence of multiple convergence groups and is consistent with the theoretical model

population growth and natural resource scarcity long run development under seemingly unfavorable conditions in this paper i consider an economy that is constrained by the use of natural resources and driven by knowledge accumulation resources are essential inputs in all sectors i show that population growth and poor input substitution are not detrimental but on the contrary are even necessary to obtain a sustainable consumption level i find a general rule to define the conditions for a constant innovation rate the rule does not apply to capital but to labor growth which is the crucial input in research furthermore the rule relates to the sectoral structure of the economy and to demographic transition the results continue to hold with a backstop technology and are extended for the case of minimum resource constraints

a tale of two market failures technology and environmental policy abstract market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies these combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives and can be cost effectively harnessed through the use of economic incentive based policy in the presence of weak or nonexistent environmental policies investments in the development and diffusion of new environmentally beneficial technologies are very likely to be less than would be socially desirable positive knowledge and adoption spillovers and information problems can further weaken innovation incentives while environmental technology policy is fraught with difficulties a long term view suggests a strategy of experimenting with policy approaches and systematically evaluating their success

fertility choice under child mortality and social norms abstract in most demographic transitions declines in child mortality precede declines in net fertility rates variants of the barro becker model of fertility fail to deliver this link a simple extension the inclusion of social norms regarding fertility generates the desired effect

birth rates and border crossings latin american migration to the us canada spain and the uk we use census data for the us canada spain and uk to estimate bilateral migration rates to these countries from 25 latin american and caribbean nations over the period 1980 to 2005 latin american migration to the us is responsive to labor supply shocks as predicted by earlier changes in birth cohort sizes and labor demand shocks associated with balance of payments crises and natural disasters latin american migration to canada spain and the uk in contrast is largely insensitive to these shocks responding only to civil and military conflict the results are consistent with us immigration policy toward latin america which is relatively permissive toward illegal entry being mediated by market forces and immigration policy in the other countries which favor skilled workers and asylum seekers among other groups insulating them from labor market shocks in the region

contraception and development a unified growth theory this study investigates the interaction of the use of modern contraceptives fertility education and long run growth it develops an economic model that takes into account that sexual intercourse is utility enhancing and that birth control by modern contraceptives is more efficient but more costly than traditional methods the study shows how a traditional economy in which modern contraceptives are not used gradually converges toward a high growth regime in which modern contraceptives are used lower prices or higher efficacy of contraceptives are conducive to an earlier onset of the fertility transition and a quicker takeoff to modern growth

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd
