endogenous discounting the world saving glut and the u s current account abstract we study the evolution of the u s current account in a two country dynamic stochastic endowment model in which a single non state contingent bond is the only internationally traded asset the paper focuses on the world saving glut as the primary cause of continual deterioration in the current account and departs from the standard framework by introducing a three parameter model of the subjective discount factor that depends on societal per capita variables that are external to household choices when agents in the model are presented with u s and rest of world endowment data as the realization of the exogenous state vector endogenously driven short run international differences in subjective discounting that display increasing relative u s impatience create saving and current account imbalances that matches patterns observed in the data

intertemporal substitution and durable goods long run data abstract in this paper we use long run annual data to estimate the intertemporal elasticity of substitution while accounting for the intra temporal substitution between nondurable consumption goods and durable consumption goods we apply a two step procedure that combines a cointegration approach to preference parameter estimation with generalized method of moments

games parents and adolescents play risky behaviors parental reputation and strategic transfers this article examines parental reputation formation in intra familial interactions in a repeated two stage game children decide whether to drop out of high school or daughters decide whether to have births as teens and parents then decide whether to provide support to their children beyond age 18 drawing on milgrom and roberts 1982 and kreps and wilson 1982 we show that under certain conditions parents have the incentive to penalise older children for their adolescent risk taking behaviour in order to dissuade their younger children from such behaviour when reaching adolescence we find evidence in favour of this parental reputation model

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

the labor supply response to mismeasured but predictable wage changes most panel data studies of intertemporal labor supply assume classical measurement error recent validation studies refute this assumption in this study i address nonclassical measurement error explicitly i use data on males from the panel study of income dynamics validation study to purge measurement error from the panel study of income dynamics i find a large amount of predictable wage variation in the data even after allowing for measurement error however there is almost no labor supply response to these predictable wage changes therefore failure to control for nonclassical measurement error cannot explain the low estimated labor supply elasticities in other papers

tough love and intergenerational altruism tough love and intergenerational altruism this article develops and studies a tough love model of intergenerational altruism we model tough love by modifying the barro becker standard altruism model in two ways first the child s discount factor is endogenously determined so lower childhood consumption leads to a higher discount factor later in life second the parent evaluates the child s lifetime utility with a constant high discount factor our model predicts that parental transfers will fall when the child s discount factor falls this is in contrast with the standard altruism model which predicts that parental transfers are independent of exogenous changes in the child s discount factor

ontology and the study of social reality emergence organisation community power social relations corporations artefacts and money the conception of social reality i have previously defended and here extend positing features such as social relations positions and powers is thoroughly naturalistic and even consistent with modern interpretations of quantum field theory it also serves to ground a social science that can be scientific in the sense of natural science this is the thesis defended here central to the argument is an emphasis on a strong form of emergence and the category of organisation in process to bring out various salient features of the position defended i take the opportunity to compare aspects of it with relevant components of the contribution of john searle whose ontological conception appears at once to be both very similar yet also very different copyright the author 2012 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

inter vivos transfers and intended bequests abstract empirical work on intergenerational transfers has focused on distinguishing between altruistic and exchange motivated behavior however these two models are unable to explain the strong tendency for inter vivos transfers to be negatively related to the income of the recipient while bequests bear no relationship to income this paper presents a new framework for analyzing transfers from parents to children that is more consistent with observed behavior than are the altruistic and exchange models alone in particular the model developed here predicts differing behavior with respect to inter vivos transfers and bequests due to liquidity constraints and uncertainty about the recipient s permanent income the empirical work uses data from the health and retirement study and the asset and health dynamics study the patterns observed in these data are consistent with earlier findings that inter vivos transfers go disproportionately to less well off children while bequests are divided equally across children further the results support the predictions of the model in that differences in inter vivos transfers arise from differences in current income while differences in bequests result when indicators of the children s permanent incomes differ

what s in a name tony lawson on neoclassical economics and heterodox economics in this article i respond to tony lawson s what is this school called neoclassical economics lawson s paper is provocative because it reformulates neoclassical economics based on veblen s original intent as a mismatch created by recognising the value of an evolutionary approach to the economy whilst remaining over reliant on elements of a taxonomic approach for lawson many heterodox economists may be neoclassical under this description i argue that there is clearly a case to be heard but that the reformulation of the neoclassical raises a number of issues there are issues concerning the specific critique of the current usage of the term neoclassical regarding genealogy and meaning there are specific issues regarding the further development of the new old veblen definition of the neoclassical how clear is the definition in a practical context as a way to identify a neoclassical group based on the commitments of the critique and the definition what does it mean to be more realistic and what is the strategic value of such a provocation for heterodoxy i argue that the combination of these are reasons for more consideration of issues of social ontology not less insofar as the terms of the argument are incomplete and this invites both lawson and those he is criticising to progress the argument particularly on method

occupational choice and the spirit of capitalism the british industrial revolution triggered a socioeconomic transformation whereby the landowning aristocracy was replaced by industrial capitalists rising from the middle classes as the economically dominant group we propose a theory of preference formation under financial market imperfections that can account for this pattern parents shape their children s preferences in response to economic incentives middle class families in occupations requiring effort skill and experience develop patience and a work ethic whereas upper class families relying on rental income cultivate a refined taste for leisure these class specific attitudes which are rooted in the nature of preindustrial professions become key determinants of success once industrialization transforms the economic landscape i introduction the industrial revolution was more than capital accumulation and growth it also set off a social and political transformation that redefined hierarchies in society and reshaped the distribution of income and wealth before the onset of industrialization in eighteenth century britain wealth and political power were associated with the possession of land over the course of the nineteenth century a new class of entrepreneurs and businessmen emerged as the economic elite for the most part the members of this class rose from humble beginnings and had their social origins in the urban middle classes the landed elite was left behind and eventually lost its political and economic predominance many observers of the time linked this reversal in economic fortunes to differences in values attitudes and ultimately preferences across social classes there are countless examples both in scholarly and in fictional writing of portrayals of members of the landowning class as averse to work unwilling to save ill disposed tocommercialactivity andunabletoconsidermoneyassomething

new evidence on altruism a study of tiaa cref retirees this paper investigates the role in household wealth accumulation of saving for bequests it employs data from a 1988 survey of tiaa cref annuitants designed to measure pension and other net worth as well as lifetime earnings about half of the households in the data plan to leave estates and the authors find that their behavior conforms with theoretical altruistic models for the same families the amount of wealth that the authors attribute to estate building is large nevertheless altruism towards one s children does not seem to be the major explanation of saving in the overall sample copyright 1996 by american economic association

the saving retention coefficient in the long run and in the short run evidence from panel data abstract the high correlation between domestic investment and saving found by feldstein and horioka in 1980 is by now considered a stylized fact pooling annual data for 21 oecd countries krol challenged this consensus in 1996 and found a much lower correlation than is usually admitted in the literature in this paper we show that krol does not overturn feldstein and horioka even if the degree of capital mobility is higher in the short run than in the long run we solve this apparent contradiction by excluding luxembourg from the panel and estimating an error correction form of krol s fixed effects model

saving growth and investment a macroeconomic analysis using a panel of countries this paper provides a descriptive analysis of the long and short run correlations among saving investment and growth rates for 123 countries over the period 1961 94 three results are robust across data sets and estimation methods i lagges saving rates are positively related to investment rates ii investment rates granger cause growth rates with a negative sign iii growth rates granger cause investment with a positive sign

an equilibrium model of child maltreatment we propose a dynamic equilibrium model of human capital development of a child that can explain why a parent child relationship might lead to child maltreatment assuming that a parent cannot observe a child s human capital accumulation or effort and that the child s time preference develops endogenously an unstable path of the parent s beliefs regarding the child can persist in equilibrium when the parent faces a high degree of uncertainty in inferring the child s human capital the parent with an initial high estimate of the human capital then tends to underestimate the child s effort which results in persistently punitive abusive nteractions

saving investment and international capital mobility in ec countries abstract drawing on different assumptions on the behaviour of the private and public sectors and on alternative scenarios of international capital mobility causality relationships are derived between saving and investment and between the private sector and public sector saving investment gaps cointegration is used to measure the resulting relationships between these sets of variables in ec countries over the 1960 1988 period the paper shows that there has been a lack of any reaction by budgetary policy to the current account balance in all the countries under study furthermore the empirical results suggest that capital controls have been the main instrument used to target the external balance

accounting for the u s earnings and wealth inequality we show that a theory of earnings and wealth inequality based on the optimal choices of ex ante identical households that face uninsured idiosyncratic shocks to their endowments of efficiency labor units accounts for the u s earnings and wealth inequality almost exactly

an analysis of the interaction among savings investments and growth in turkey turkey has been implementing tight fiscal and monetary policies for years these policies rely on the basic understanding that savings trigger growth and investments however there are alternative theoretical discussions and empirical findings related to the interaction among these variables in this study while one of the purposes is to analyse the interaction among these variables for the turkish case the other is to try to bring an insight for other developing countries for the issues such as data production econometric analysis and as well as making policy suggestions in line with the evidence from the turkish case the findings of this study show that it is the growth that induces both savings and investments hence it is necessary to question policies that assume it is the savings triggering growth and investments

explaining saving investment correlations national saving and investment rates are highly positively correlated in virtually all countries this is puzzling as it apparently implies a low degree of international capital mobility this paper shows that the observed positive correlation between national saving and investment rates arises naturally within a quantitatively restricted equilibrium model with perfect mobility of financial and physical capital the model is consistent with the fact that saving investment correlations are larger for larger countries but are still substantial for small countries further the model is consistent with the finding that current account deficits tend to be associated with investment booms copyright 1993 by american economic association

capital mobility in the world economy an alternative test abstract this paper proposes a new measure and test of international capital mobility in order to investigate capital flows we utilize a small open economy version of campbell and mankiw s nber macroeconomic annual 1989 185 216 permanent income model our capital mobility measure focuses on the correlation between the country s consumption and net output instead of the correlation between domestic saving and domestic investment proposed by feldstein and horioka economic journal 90 1980 314 329 the model is estimated for 11 oecd countries the results suggest that the null hypothesis of perfect capital mobility cannot be rejected for more than a half of these countries on the other hand some kind of capital mobility constraints are detected for several countries including the united states and japan

social positioning and the nature of money the question of the nature of money is pursued drawing on results generated in the field of social ontology as well as on observations from history the conception of the nature of money found in this manner to be the most sustainable is compared to various other prominent if usually held to be mutually incompatible theories

do borders matter evidence from japanese regional net capital flows are international borders barriers to capital flows we use evidence on net capital flows among regions within a country as a benchmark for this purpose we develop a data set of saving and investment rates of japanese prefectures we find that the correlation between saving and investment rates is higher for oecd countries than for japanese regions in both time series and cross sectional data after controlling for factors that are expected to contribute to a positive correlation in the absence of barriers to capital flows we conclude that primarily long term capital flows are hindered by national borders as reflected in the cross sectional evidence

the social discount rate what discount rate should be applied to social investments it is standard to use the market interest rate thereby respecting private preferences we show that application of this revealed preference criterion rests on faith not on logic it is justified only if preferences over all choices including past choices are time invariant the conditions for this to be true are stringent under more reasonable conditions policy makers should be more patient than private citizens whose choices define the most short sighted pareto optimum

opportunity and social mobility the fact that the children of rich parents have better economic prospects than the children of poor parents unequal opportunity is generally thought to be one of the weak points of modem capitalist societies the ability of the descendants of poor families to eventually become rich and the descendants of rich families to eventually become poor social mobility is commonly considered to be one of the strong points of these societies here i argue that both of these characteristics are in fact necessary implications of an efficient societal arrangement when incentives to work hard must be provided i argue this point using a generational version of the model of phelan and townsend 1991 an infinitely repeated general equilibrium economy with incentive constraints in my model each household s stochastic output is a function of its level of effort since effort is assumed to be costly and privately observed households can shirk higher than minimal effort levels must be induced by making a household s present or future consumption dependent on the household s observed output history a large literature considers models similar to this including green 1987 atkeson and lucas 1992 phelan 1994 1995 wang 1995 hopenhayn and nicolini 1997 khan and ravikumar 2002 the main difference between the economies in that literature and here is that here instead of a household consisting of a single infinitely lived individual a household consists of a sequence of altruistically linked individuals a familial dynasty each of whom lives for one period this difference affects the appropriate societal ranking of allocations when households consist of a single infinitely lived individual allocations can be ranked according to their implied distributions of ex ante lifetime utilities if one allocation delivers a distribution of ex ante utilities dominated by another allocation then the first allocation is inefficient however if a household consists of a sequence of altruistically linked individuals then the appropriate ranking of allocations is no longer obvious how those in the first generation rank allocations will in general differ from how their descendants rank allocations this paper addresses this conflict between generations by ranking allocations according to a rawlsian veil of ignorance criterion rawls 1971 that is here society seeks to maximize the expected dynastic utility utility including altruism toward descendants of an individual who does not know into which generation he will be born and the identity or output levels of his ancestors 1 i argue that this corresponds to a societal ranking which does

wealth varying intertemporal elasticities of substitution evidence from panel and aggregate data abstract this paper constructs and estimates a model of consumer preferences in which the intertemporal elasticity of substitution ies of consumption expenditure rises with the level of wealth the purpose of this paper is to measure the effect that systematic variation in the ies of poor and rich consumers has on the ies of aggregate consumption expenditure we find economically significant differences in the ies of poor and rich consumers in indian panel data on the consumption of individual households we also find economically significant differences in the ies measured in aggregate time series data for the u s and india

the limits of ontological critique from judgmental rationality to justification the cambridge social ontology cso programme s inability to generate a meaningful dialogue with mainstream economics is difficult to understand by mere reference to judgmental rationality and without reference to cso s ideological configuration our paper uses an economie des conventions framework to draw systematic comparisons between cso s ideological configuration and the ideological configurations of mainstream economic theories and practice the resulting analysis helps us to understand not only why cso generated little response from the mainstream but also how cso might renew its critique in ways that might be more likely to produce a response

the international transmission of economic fluctuations abstract this paper suggests that for a wide class of international real business cycle models including models with imperfect competition the traditional channels of international transmission of business cycles through world interest rate and terms of trade variations cannot explain the cyclical response of the canadian economy to innovations in u s output empirically testable quantitative models of the effects on canadian economic activity of shocks to the u s economy are developed and their empirical relevance is tested by comparing impulse responses estimated from vector autoregressions to the quantitative predictions of the theoretical models

estimating saving investment correlations evidence for oecd countries based on an error correction model abstract saving investment correlations are important stylized facts in open economy macroeconomics and indicators of capital mobility they are best estimated by an error correction model ecm because an ecm is consistent with intertemporal general equilibrium models the ecm is a synthesis of previous approaches applying the ecm to the oecd countries we find that in general saving and investment are cointegrated the ecm is more powerful in detecting cointegration than the two step engle granger procedure estimates of the saving investment correlation are robust with respect to overdifferencing we find evidence of a large country effect and an increase in capital mobility within the oecd area

rate of time preference intertemporal elasticity of substitution and level of wealth the rate of time preference rtp and the intertemporal elasticity of substitution ies are two important factors shaping intertemporal consumption decisions models in which the rtp and or the ies differ systematically between rich and poor households have different empirical and policy implications for economic development growth and the distribution of income and consumption from those of standard models in which these parameters are constant across households in this chapter we estimate a model in which both rtp and ies are allowed to differ across rich and poor households using household level panel data from india our empirical results are consistent with the view that the rtp is constant across poor and rich households but the ies is larger for the rich than it is for the poor

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

are saving and investment cointegrated an ardl bounds testing approach using the newly developed ardl bounds testing procedure we find that as implied by the intertemporal budget constraint u s saving and investment rates cointegrate in all sample periods considered our results also show that the saving investment correlation weakens after 1971 suggesting that the feldstein horioka approach provides an at least partially informative measure of capital mobility

economics as progress the lse approach to econometric modelling and critical realism as programmes for research in the face of claims that economics is increasingly driven merely by fashion this paper draws out certain similarities and differences between two self consciously progressive and developmental research programmes namely the lse approach to econometric modelling and critical realism in economics the argument is that while these two programmes of research share a common point of departure and possess many common elements what at root distinguishes them is their adoption of opposing philosophical orientations the comparison enables both the nature of each programme and the relevance of their common concerns to be more easily appreciated and helps clarify the sort of evidence that would provide a basis for selecting one project over the other copyright 2005 oxford university press

cointegration of long span saving and investment abstract we find that saving and investment cointegrate in all or most countries in maddison s research memorandum no 443 1991 long span data set by a variety of time series and panel data tests we interpret our results as reflecting current account solvency and not capital immobility

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

a critical realist interpretation of evolutionary growth theorising the article discusses a critical realist interpretation of evolutionary growth theorising by focusing on some of its basic characteristics the evolutionary ontology is complex differentiated structured systemic open ever changing and radically uncertain its methodology tends to be increasingly based on appreciative theorising retroductive explanations and interdisciplinary analysis after discussing these features the article suggests that critical realism may indeed constitute an important philosophical and methodological foundation for the future development of evolutionary theories of economic growth

international capital mobility evidence from panel data abstract to test whether capital is internationally mobile some researchers have examined the relationship between saving and investment using time averaged data they find saving and investment to be related and conclude that capital is relatively immobile in this paper i argue that a country s intertemporal budget constraint biases results using time averaged data against finding capital mobility using annual data pooled for 21 oecd countries over the 1962 1990 period i find the estimated impact of saving on investment to be considerably smaller than previous estimates

motives for private income transfers private income transfers are becoming increasingly recognized as a key aspect of the u s economy the majority of private income transfers occur inter vivos i e between living persons but very little is known about this type of transfer behavior this paper tests alternative hypotheses concerning motivation for inter vivos transfers two motives are considered altruism and exchange evidence presented here casts doubt on the altruistic model of transfer behavior observed patterns for inter vivos transfers are more consistent with exchange related motives this finding has important implications for the effects of public transfer programs on the distribution of economic well being

mothers and sons preference formation and female labor force dynamics this paper argues that the growing presence of a new type of man one brought up in a family in which the mother worked has been a significant factor in the increase in female labor force participation over time we present cross sectional evidence showing that the wives of men whose mothers worked are themselves significantly more likely to work we use variation in the importance of world war ii as a shock to women s labor force participation as proxied by variation in the male draft rate across u s states to provide evidence in support of the intergenerational consequences of our propagation mechanism

a model intervenes the many faces of moral hazard this article builds on advances in social ontology to develop a new understanding of how mainstream economic modelling affects reality we propose a new framework for analysing and describing how models intervene in the social sphere this framework allows us to identify and articulate three key epistemic features of models as interventions specificity portability and formal precision the second part of the article uses our framework to demonstrate how specificity portability and formal precision explain the use of moral hazard models in a variety of different policy contexts including worker compensation schemes bank regulation and the euro sovereign debt crisis

parental altruism and inter vivos transfers theory and evidence this paper uses psid data on the extended family to test whether inter vivos transfers from parents to children are motivated by altruism specifically the paper tests whether an increase by one dollar in the income of parents actively making transfers to a child coupled with a one dollar reduction in that child s income results in the parents increasing their transfer to the child by one dollar this restriction on parental and child transfer income derivatives is derived for the standard altruism model augmented to include uncertainty and liquidity constraints these additional elements pin down the timing of inter vivos transfers the method used to estimate income transfer derivatives takes into account unobserved heterogeneity across families in the degree of altruism the findings strongly reject the altruism hypothesis redistributing one dollar from a recipient child to donor parents leads to less than a 13 cent increase in the parents transfer to the child far less than the one dollar increas

an incentive model of the effect of parental income on children economists explain the positive relationship between parental income and children s outcomes using an investment model building on work in psychology and sociology this paper emphasizes the importance of child rearing practices which vary with income i argue that parents ability to mold their children s behavior through pecuniary incentives is limited at low incomes leading to lower outcomes and increased reliance on nonpecuniary mechanisms such as corporal punishment my model generates a positive relationship between parental income and children s outcomes especially at low incomes and endogenously produces a relationship between parental income and child rearing practices empirical work confirms these implications

inequality and social discounting we explore steady state inequality in an intergenerational model with altruistically linked individuals who experience privately observed taste shocks when the welfare function depends only on the initial generation efficiency requires immiseration inequality grows without bound and everyone s consumption converges to zero we study other efficient allocations in which the welfare function values future generations directly placing a positive but vanishing weight on their welfare the social discount factor is then higher than the private one and for any such difference we find that consumption exhibits mean reversion and that a steady state cross sectional distribution for consumption and welfare exists with no one trapped at misery

the nature of heterodox economics heterodoxy serves as an umbrella term to cover the coming together of separate projects or traditions in answering the question what distinguishes heterodoxy from the orthodoxy the author argues that matters of ontology are central in answering the question how are the various traditions that make up the modern heterodoxy to be distinguished from each other the author defends criteria other than varying commitments to specific substantive theories policy measures or techniques or basic units of analysis

tough love and intergenerational altruism this chapter develops and studies a tough love model of intergenerational altruism we model tough love by modifying the barro becker standard altruism model in two ways first the child s discount factor is endogenously determined so lower childhood consumption leads to a higher discount factor later in life second the parent evaluates the child s lifetime utility with a constant high discount factor our model predicts that parental transfers will fall when the child s discount factor falls this is in contrast with the standard altruism model which predicts that parental transfers are independent of exogenous changes in the child s discount factor
