capital income taxation and welfare in a small open economy abstract the paper studies the effects of various capital income tax policies in a small open economy households are infinitely lived and possess endogenous time preferences investment by firms is subject to adjustment costs it is shown that welfare paradoxes may exist in that increases in tax instruments may improve welfare

delay aversion under a general class of preferences abstract i study the characterization of delay aversion in a general class of intertemporal utility functions by adapting the behavioral definition introduced by benoit and ok 2007 i show that when the utility functions are partially differentiable an agent is more delay averse if and only if he has higher marginal intertemporal rate of substitution between any two consecutive consumption periods when preferences are represented by a recursive utility function not necessarily differentiable i provide a simple transformation rule to represent a more delay averse agent

redistributive taxation in a small open economy this paper studies the effects of redistributing the tax burden across households on the current account the set up is a dynamic small open economy with infinitely lived households that have perfect foresight it is shown that the different speeds at which households adjust consumption levels to their long run values may cause nonmonotonic transient paths

optimum responses of the current account when income is uncertain abstract how the current and capital accounts in the balance of payments should adjust when there are exogenous shocks has recently been examined in the context of optimal intertemporal choice of consumption and borrowing thus a fall in income will call forth a variety of responses depending on whether it is thought to be permanent or temporary long term or short term and on the form of the discount function in this paper uncertainty is introduced into the timing of the reversal of an income fall this being modelled by a poisson process phase diagrams are derived for the paths of consumption and debt

migration from nicaragua some recent evidence abstract i utilize two unique data sources to examine migration from and remittance flows to the capital city of managua nicaragua approximately 10 12 of the population has emigrated these emigrants tend to be disproportionately of working age better educated and more often white collar workers than nonmigrants in addition emigrants are more likely to come from larger premigration households and higher income households remittance flows to managua are quite large the second largest source of foreign exchange earnings after coffee in addition remittances have a negative income effect on labor force participation and a positive effect on self employment of nonmigrants

elastic capital supply and the effects of fiscal policy i introduction perfectly elastic or perfectly inelastic supply or demand curves have much to recommend them equilibrium analysis which would otherwise be fraught with ambiguity yields forth sharp predictions when one assumes either demand or supply are either perfectly elastic or inelastic nonetheless this is not the way we typically teach equilibrium analysis nor in most circumstances perform it neoclassical macroeconomics is an exception to this rule specifically capital accumulation models in which a representative agent maximizes the standard additively separable fixed discount factor utility function to which class most equilibrium business cycle models based on the neoclassical growth model belong imply a long run supply curve for capital which is perfectly elastic at the agent s fixed rate of time preference this property of what we will refer to as the standard model is and has been well known and well criticized even by users of the standard model 1 but the question of exactly where and when this assumption ceases to be innocuous i e for what sorts of experiments it is or isn t a harmless simplification has been given surprisingly short shrift 2 in this paper we explore the implications for the equilibrium analysis of the effects of changes in government purchases of relaxing this assumption in particular we explore the implications of replacing the fixed discount factor beta in the standard utility specification summation of beta sup t u c sub t l sub t where t 0 to infinity where c sub t and l sub t denote consumption and leisure at date t with an endogenous discount factor beta c sub t l sub t in this way discounting of future utility is allowed to depend on the agent s enjoyment of current consumption and leisure the lifetime utility function that results from this modification is of the sort first formulated by uzawa 1968 and epstein and hynes 1983 the latter of these in particular demonstrated through a series of examples the extent to which models with endogenous discount factors can differ substantially from their fixed discount factor counterparts while these earlier papers were primarily concerned with developing theoretical results our analysis will be primarily quantitative the possibility that the rate of time preference varies across individuals and over time or equivalently that the rate at which the future is discounted responds to the current and previous decisions of individuals is more than a theoretical curiosum to start with there is a substantial body of evidence that rates of time preference differ across individuals people are not equally patient much of this evidence is summarized in table 1 of becker and mulligan 1997 at the aggregate level they point to the fact that rich countries have grown slightly faster than poor countries over the past 30 years as suggesting that the residents of rich countries may have lower rates of time preference than residents of poor countries differences between the united states and japan in the age consumption profile are also consistent with differences in the rate of time preference between the united states and japan and the fact that income is associated with consumption growth suggests that the rich may be more patient than the poor detailed micro evidence on differences in rates of time preference across households is also presented by lawrance 1991 she finds that the rates of time preference of poor consumers are three to five percentage points higher than those of rich consumers using panel data for the united states from the psid ogaki and atkeson 1997 estimate a model in which time preference is allowed to vary across rich and poor households using household level panel data from india furthermore there is evidence that rates of time preference vary not just across individuals at a point in time but also over time

the rate of time preference and dynamic economic analysis strong restrictions on the structure of preferences are a central feature in the received theory of intertemporal allocation in fact most of the modern literature concerned with capital theoretic problems represents preferences by a functional in which an additive utility function is discounted by a constant rate of time preference this specification is attractive because it is analytically tractable in dynamic models and it clearly delineates how tastes and opportunities interact to determine an economy s household s paths of consumption and capital formation however its rigid structure constancy of time preference severely limits the conclusions and explanatory power of the corresponding models this paper considers a class of utility functionals in continuous time which have the appealing feature that the rate of time preference depends systematically on an index of aggregate future consumption the more flexible structure embodied in these functionals leads to important generalizations and

small island developing states and their economic vulnerabilities abstract many small island developing states sids face special disadvantages associated with small size insularity remoteness and proneness to natural disasters these factors render the economies of these states very vulnerable to forces outside their control a condition which sometimes threatens their very economic viability the gdp or gnp per capita of these states often conceals this reality in this paper the major vulnerabilities faced by sids are discussed and when possible quantified in the form of an index an attempt is also made to construct a composite index of vulnerability

a gravity model of remittance determinants evidence from latin america and the caribbean abstracta gravity model of remittance determinants evidence from latin america and the caribbean regional studies this paper constructs a microeconomic model of the motivation for remittances and uses it to explore the macroeconomic determinants in addition a new measure of bilateral remittances is used to estimate a gravity model of remittances for 27 latin american and caribbean countries and 18 industrialized countries the results suggest remittances are motivated by a combination of altruism and self interest both of which are encapsulated by economic and non economic variables

effects of government spending on the current account with endogenous time preference this paper extends a previous model to set up a small open economy with perfect capital mobility and examines the effects of an unanticipated permanent rise in public spending on the optimal rates of private consumption and the current account the novelty of the paper is consideration of the relationship between private and public consumption in the household s utility function as well as endogenous rates of time preference it is found that the key factor determining the adjustment patterns of private consumption and the current account is the marginal utility of private consumption and of public spending which results from endogenous recursive preferences

habit persistence and the harberger laursen metzler effect in an infinite horizon model abstract the habit persistence model of ryder and heal is used to examine the harberger laursen metzler h l m effect our results are in contrast to the general view in the literature that the stability requirements preclude the h l m effect in an infinite horizon model we show that if the marginal utility of real consumption is strongly increasing in the habitual standard of living then the h l m effect holds and a terms of trade deterioration reduces savings however if the marginal utility of real consumption is not sufficiently strongly increasing or is decreasing in the habitual standard then the h l m effect is overturned

self control and the theory of consumption to study the behavior of agents who are susceptible to temptation in infinite horizon consumption problems under uncertainty we define and characterize dynamic self control dsc preferences dsc preferences are recursive and separable in economies with dsc agents equilibria exist but may be inefficient in such equilibria steady state consumption is independent of initial endowments and increases in self control increasing the preference for commitment while keeping self control constant increases the equity premium removing nonbinding constraints changes equilibrium allocations and prices debt contracts can be sustained even if the only feasible punishment for default is the termination of the contract

optimum borrowing and the current account when there are fluctuations in income abstract current account issues are examined in a context in which expenditure and borrowing are chosen optimally permanent falls in income are first discussed and the analysis deals with fixed and endogenous discount rates and interest rates a smoothing response in consumption producing a current account deficit is shown to follow a short term income fall however a long term fall can call forth an adjustment response with consumption and debt first moving toward the equilibrium which would obtain if the income fall were permanent

capital controls policy an intertemporal perspective abstract this paper studies capital controls policy from an intertemporal perspective using a small open economy model with optimizing agents it derives a policy rule which conforms real world stylized facts and is sustainable in the long run in particular it explicitly models the constraints on the policy rule implied by the dynamics of the economy studying several prevalent policy experiments it is demonstrated that significant real effects are generated by the interaction between controls policy and traditional policy tools this happens as controls affect agents intratemporal asset allocation and intertemporal consumption patterns the use of controls enlarges the set of possible outcomes generating some non traditional results the analysis points to new tradeoffs and hence new dilemmas faced by a government that uses controls

on the existence of balanced growth equilibrium the authors characterize the class of dynamic models that allow for the most commonly used types of sustained economic growth balanced and asymptotically balanced they show that under a constant returns to scale technology asymptotically constant discount rate and asymptotically constant elasticity of marginal felicity are not only necessary but also sufficient conditions for the existence of a n asymptotically balanced growth equilibrium path the authors provide examples of recursive utility models that accept a n asymptotically balanced growth equilibrium and discuss their implications on cross country differences in growth rates as well as on savings behavior and wealth distribution copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

time preference and life cycle consumption with endogenous survival we provide a structural theory of time preference and derive a functional form of intertemporal preferences by postulating that individuals make their life cycle consumption choices as if to maximize expected lifetime this yields a nontime separable expected utility representation where the inverse of the coefficient of intertemporal substitution exceeds the coefficient of relative risk aversion the rate of time preference depends on the inverse of expected remaining lifetime and the effect of age on the productivity of consumption in affecting health the preference formulation is applied in a standard intertemporal consumption model to illustrate the implied life cycle consumption choices

remittances liquidity constraints and human capital investments in ecuador summary over the last decade ecuador has experienced a strong increase in financial transfers from migrated workers this paper investigates how remittances via trans national networks affect human capital investments through relaxing resource constraints and facilitate households in consumption smoothing by reducing vulnerability to economic shocks our results show that remittances increase school enrollment and decrease incidence of child work especially for girls and in rural areas furthermore we find that aggregate shocks are associated with increased work activities while remittances are used to finance education when households are faced with these shocks 2008 elsevier ltd all rights reserved

zero time preference with discounting abstract for the uzawa class of utility functionals t 1 v c t e i t c i we investigate the case of v ct a 1 e ct the case has a zero rate of time preference and the functional attains a maximum in finite horizon problems of economic growth the curvature of the production function is crucial in determining the nature of the solution to problems in economic growth with the above optimand

a simple dynamic general equilibrium model abstract we analyse a single sector economy with h 1 infinitely lived agents that operate in a continuous time framework utility functions are recursive but not additive both efficient and perfect foresight competitive equilibrium allocations are considered the existence and stability of such allocations are investigated locally i e in a neighbourhood of steady state allocations the model is shown to be useful for explaining the distribution of wealth and consumption across agents and for analysing the way in which wealth redistribution can affect the dynamics of aggregate economic variables

asymptotic behavior and optimal properties of a consumption investment model with variable time preference abstract this paper analyzes the convergence properties and the determination of an optimal consumption path in the consumption investment model of uzawa 1968 sufficient conditions for the existence and uniqueness of the optimal path are presented components of the utility functional are recovered when the optimal path is piecewise affine the model is applied to the determination of the interest rate and income distribution under time preference differentials

a theory of time preference grant a taylor this article proposes that people generally prefer present consumption to future consumption because their expected utility from consumption eventually falls as their mental and physical abilities eventually decline with age moreover contrary to the ubiquitous intertemporal formulation with a constant rate of time preference and contrary to three recent theories of time preference that predict decreasing discounting as people age this article asserts that discounting increases over the life cycle this hypothesis is supported by data from the panel study of income dynamics as well as evidence from numerous previous studies jel d91 1 introduction despite the almost universal assumption of time preference in models of intertemporal choice an adequate explanation of why people discount the future has not been provided 1 olsen and bailey 1981 make a convincing case for positive time preference by contradiction i e without time preference models of intertemporal choice do not yield predictions consistent with observed behavior but they do not explain why individuals would rationally discount the future 2 three recent studies have attempted to provide the explanation rogers 1994 argues that societies that discount the future at a rate of about 2 will be the long run survivors in an evolutionary fitness situation 3 posner 1995 argues that discounting occurs because individuals have multiple selves that is people are weighting their present consumption far more heavily than their future consumption because the present self and the future self are in some meaningful sense separate persons 92 becker and mulligan 1997 argue that discounting occurs because of a rational defective recognition of future utilities 730 but as will be shown these three theories are inconsistent with empirical evidence on consumption over the life cycle in at least one important aspect this article constructs and empirically supports a new theory of time preference the hypothesis is that people do not have an intrinsic preference for present consumption relative to future consumption instead the instantaneous utility function also known as the felicity function is expected to vary with age just as people s physical and mental abilities vary with age in other words the ability to enjoy consumption eventually deteriorates over the life cycle along with other abilities this life cycle view of the expected utility function causes people to rationally devalue consumption in periods of low expected felicity that is discount future consumption perhaps this is what is meant by the cliche don t wait until you are too old to enjoy it moreover this causes individuals implicit discount rates to vary systematically with age 4 in fact this provides the testable implication of the theory the standard specification of intertemporal preferences holds the discount rate constant over th e life cycle 5 to be more precise in the early stage of the life cycle the capacity to enjoy consumption may be expected to rise hence a young individual s discount rate may be negative figure 1 illustrates this possibility with a hypothetical adult life cycle marginal felicity function for a given level of consumption u sub c c a c denotes consumption and a denotes age and its corresponding discount rate function rho a the vast majority of wealth is held by older people that is those in the declining stage of their abilities thus the preference for present consumption over future consumption appears to hold in the aggregate this view of intertemporal preferences may at first seem inconsistent with practically all dynamic analyses which are based on the notion of stationary utility on further consideration however the hypothesis is quite consistent with modern consumer theory since becker 1965 it has been widely accepted that households derive utility from commodities that are produced with market goods combined with household time and skills i

capital accumulation and the current account in a two country model abstract this paper examines the joint determination of international debt and capital accumulation in a two country model national rates of time preference are endogenous adjusting along an optimal path to come into equality with one another in the steady state the characteristics of short run current account dynamics are crucially linked to world capital accumulation and to a country s long run net external asset position steady state creditor countries tend to have current account surpluses during episodes of world output growth and vice versa for debtor countries this gives rise to possible non monotonic adjustment in the current account and consumption

government purchases and real interest rates with endogenous time preference abstract the observation of low real interest rates during periods of high temporary government purchases such as wars can be reconciled with the neoclassical growth model extended to allow for endogenous time preference temporary increases in government purchases lead to a fall in the instantaneous rate of time preference this may result in rising investment and falling real interest rates along an adjustment path

endogenous discounting via wealth twin peaks and the role of technology we endogenize the discount rate via wealth and provide evidence that wealth affects the discount rate negatively we give a necessary and sufficient condition for endogenous discounting to lead to the twin peaks of economic growth and show that improvements in technology help avoid them

hyperbolic discounting and endogenous growth this paper provides the closed form solution for the standard model of endogenous growth when consumers have present biased preferences and make time inconsistent savings plans which they revise continuously it is shown that long run growth is not necessarily lower under present biased preferences in fact a strong equivalence result holds if hyperbolic discounting provides the same present value of a constant infinite income stream as standard exponential discounting then the equilibrium rate of economic growth is also the same under both discounting methods in this sense present bias preferences are harmless for economic growth

ramsey meets laibson in the neoclassical growth model the neoclassical growth model is modified to include a variable rate of time preference with no commitment ability and log utility the equilibrium features a constant effective rate of time preference and is observationally equivalent to the standard model the extended framework yields testable linkages between the extent of commitment ability and the rates of saving and growth the model also has welfare implications including the optimal design of institutions that facilitate household commitments steady state results are obtained for general concave utility functions and some properties of the transitional dynamics are characterized for isoelastic utility

the welfare cost of capital income taxation in a growing economy the welfare cost of capital income taxation is analyzed in a general equilibrium framework where the private sector is represented by a competitive household endowed with perfect foresight and an infinite life the value of the welfare cost depends essentially on the elasticity of substitution between capital and labor in the production function numerical estimates are presented for different values of the parameters of the model the welfare gain obtained by the abolition of the capital income tax is smaller when the private sector is not endowed with perfect foresight it is reduced by about 40 percent when expectations are myopic the allocation efficiency cost of the corporate tax dwarfs the intertemporal welfare cost

microeconomic implications of remittances in an overlapping generations model with altruism and a motive to receive inheritance abstract the article develops a framework to examine the interaction between the migrant and the remittance receiving relative s under non cooperative and cooperative scenarios the model has an overlapping generations structure where both parties have altruistic behavioural traits we derive the relationships between the remittances consumption labour supply savings and bequests and compare these variables under the two scenarios for both scenarios the remittances have a positive effect on the relative s leisure consumption and investment the effects of the wage and the non wage income of the relative and the migrant and the interest rate on the equilibrium level of remittances are also qualitatively similar under the two scenarios however the parties degrees of altruism as well as the discount rates have different effects on the equilibrium level and incidence of remittances for the non cooperative and cooperative interactions these shed some light on the differences in remittance behavi

macroeconomic policy exchange rate dynamics and optimal asset accumulation the paper develops a model of exchange rate and current account determination for a small economy peopled by infinitely lived utility maximizing households in this setting a central bank purchase of foreign exchange has no real effects when central bank foreign reserves earn interest at the world rate and proceeds are returned to the public in contrast an increase in the monetary growth rate does have real effects even in the long run the model developed here implies that an increase in government spending may lead to a surplus on current account the external adjustment process predicted by the model is one in which consumption real balances and external assets all rise or fall simultaneously

patience and prosperity abstract this paper introduces wealth dependent time preference into a simple model of endogenous growth the model generates adjustment dynamics in line with the historical facts on savings and economic growth in europe from the high middle ages to today along a virtuous cycle of development more wealth leads to more patience which leads to more savings and further increasing wealth savings rates and income growth rates are thus jointly increasing during the process of development until they converge towards constants along a balanced growth path during the transition to modern growth an economy in which the association of wealth and patience is stronger overtakes an otherwise identical economy and generates temporarily diverging growth rates

credit natural disasters coffee and educational attainment in rural honduras summary this paper exploits a two stage estimation approach to examine the impact on secondary school attainment in rural honduras of four key variables affecting household choices wealth credit access crop choice and shocks the first stage estimates the probability that a household is credit constrained while the second estimates secondary school educational attainment of appropriately aged children the second stage includes variables for crop selection and household wealth shocks from hurricane mitch in addition to other characteristics of the child household and community that can influence educational attainment credit constrained households have lower educational attainment and are more likely to be adversely affected by negative shocks

progressive taxation and income inequality in dynamic competitive equilibrium abstract this paper establishes the existence of a non degenerate distribution of income in a simple dynamic economy when agents who are heterogeneous in their rates of impatience face a progressive tax system in this dynamic setting income inequality can vary positively with the degree of tax progressivity moreover the inherent heterogeneity in agents behavior can explain why measures of inequality such as the standard deviation of income or atkinson s gini tend to be dynamically much more sluggish than aggregate measures such as total income finally the adjustment in the degree of inequality resulting from an exogenous change in tax policy may take some time before becoming effective this result also arises from agents asymmetric responses to policy changes

inflation and growth impatience and a qualitative equivalence this paper studies the role of an endogenous time preference on the relationship between inflation and growth in the long run in both the money in utility function miuf and transactions costs tc models we establish a qualitative equivalence between the two models in a setup without a labor leisure tradeoff when the time preference is decreasing or increasing in consumption and real balances both the miuf and tc models are qualitatively equivalent in terms of predicting a negative or positive relationship between inflation and growth in a steady state both a decreasing and an increasing time preference in consumption are consistent with the arguments found within the literature while a decreasing time preference in real balances corroborates with empirical evidence there is no evidence in support of an increasing time preference in real balances

the existence of ramsey equilibrium the authors demonstrate existence of a perfect foresight equilibrium under borrowing constraints in a one sector model with infinitely lived heterogeneous agents the class of admissible preferences includes but is not limited to recursive preferences existence is proven using a t 2ctonnement argument under appropriate conditions on preferences and technology a new measure of discounting the norm of marginal impatience is used to determine which technologies are admissible depending on the norm of marginal impatience the admissible technology may either allow for permanent growth or have a maximum sustainable stock copyright 1991 by the econometric society

the effect of male migration on employment patterns of women in nepal what is the impact of male migration on the labor market behavior of women in nepal the instrumental variable full information maximum likelihood method is applied to data from the 2004 nepal household survey to account for unobserved factors that could simultaneously affect men s decision to migrate and women s decision to participate in the labor market the results indicate that male migration has a negative impact on the level of the labor market participation by women in the migrant sending household there is evidence of substantial heterogeneity based on both observable and unobservable characteristics in the impact of male migration the findings highlight the important gender dimension of the impact of predominantly male migration on the well being of sending households strategies for economic development in nepal should take into account such gender aspects of the migration dynamics

a theory of infrastructure led development abstract this paper proposes a theory of long run development based on public infrastructure as the engine of growth the government in addition to investing in infrastructure spends on health services which in turn raise labor productivity and lower the rate of time preference infrastructure affects the production of both commodities and health services as a result of network effects the degree of efficiency of infrastructure is nonlinearly related to the stock of public capital itself provided that governance is adequate enough to ensure a sufficient degree of efficiency of public investment an increase in the share of spending on infrastructure financed by a cut in unproductive expenditure or foreign grants may facilitate the shift from a low growth equilibrium characterized by low productivity and low savings to a high growth steady state

government spending and the real exchange rate i study the effect of government spending on the real exchange rate in an open economy version of the sidrauski model with a time varying rate of time preference that introduces complementarity between consumption at different points in time i show that a balanced budget fiscal expansion causes a real depreciation and a current account surplus if the expansion falls on traded goods if the increase falls instead on nontraded goods both the stylized results of a real appreciation and a current account deficit and the perverse result of an appreciation and a surplus can occur

the global stability of efficient intertemporal allocations this paper describes a continuous time model of an economy with finitely many infinitely lived consumers and a finite number of capital goods two objectives are achieved first recursive nonadditive utility functionals are formulated and analyzed second these preference functionals are applied to analyze the nature of efficient allocations in a dynamic economy two classes of global turnpike propositions are proven which provide the basis for a model of the long run distribution of wealth these propositions also provide new perspective regarding existing stability literature based on additive utilities copyright 1987 by the econometric society

on the microeconomics of food and malnutrition under endogenous discounting abstract this paper explores the microeconomics and dynamics of food and nutrition it examines the linkages between malnutrition and the incentive to invest and accumulate capital the analysis focuses on a dynamic model where preferences about the future depend on nutrition and health situations of malnutrition cover both ends of the spectrum from nutrient deficiency to obesity the model involves preferences that are not time additive and exhibit endogenous discounting this provides a framework to investigate the factors affecting consumption and investment behavior the adverse investment incentives of malnutrition are examined

marshallian recursive preferences and growth abstract although alfred marshall adhered to the classical doctrine of impatience he thought that the act of saving might itself confer utility we model this by making the discount factor a function of savings in addition to providing an intuitive rationale for increasing marginal impatience marshallian time preference has interesting implications for macroeconomics marshallian preferences lower interest rates by stimulating savings paradoxically it is possible for a tax cut to lower interest rates in a marshallian economy in a growth model with marshallian consumers a permanent increase in government expenditures causes super crowding out of consumption and reduces the steady state capital stock

the complete complementarity of consumption and real balances and the strong superneutrality of money abstract in the representative agent model with money in the utility function if consumption and real balances are perfect complements steady state capital intensity and real balance holdings are both invariant to monetary growth regardless of the nature of time preferences

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

optimal growth with decreasing marginal impatience abstract this paper analyses the long run dynamics of a continuous time infinite horizon optimal growth model with identical households where the households rate of time preference is endogenously determined however unlike the existing literature we assume that households have decreasing marginal impatience i e the instantaneous discount rate is negatively related to the current consumption with this assumption we analyse the stability and uniqueness of the long run equilibrium we show that contrary to the general belief a negative relationship between the instantaneous discount rate and the household s current consumption does not necessarily result in instability of the dynamic system however even a stable system may be characterized by multiple equilibria so that the initial condition becomes important in determining the long run behaviour of the economy we derive a set of sufficient conditions for stability and uniqueness in this context

weakly nonseparable preferences and distortionary taxes in a small open economy this paper examines the dynamic effects of distortionary taxes in a small open economy the employed utility function implies both endogenous rates of time preference and a tractable form of weak nonseparability between consumption and leisure weak nonseparability induces novel long run welfare and wealth effects of taxes and generates very different current account movements endogenous rates of time preference facilitate the examination of a tax on international borrowing and lending copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

international migration remittances and schooling evidence from el salvador abstract we examine the effect of remittances from abroad on households schooling decisions using data for el salvador following the massive war related emigration of the 1980s remittances became a significant source of household income throughout the 1990s we use the cox proportional hazard model to examine the determinants of school attendance measuring income from a source that is uncorrelated with parental schooling remittances we find that remittances have a large significant effect on school retention we estimate that while household income net of remittances has a small though significant impact on the hazard of leaving school in rural and urban areas remittances have a much larger impact on the hazard of leaving school in urban areas the effect of remittances is at its smallest 10 times the size of the effect of other income in rural areas the effect of remittances is about 2 6 times that of other income our finding is of interest in that it suggests that subsidizing school attendance particularly in poor areas may have a large impact on school attendance and retention even if parents have low levels of schooling

do tax incentives affect charitable contributions evidence from public charities reported revenues this paper estimates the effect of the charitable contribution tax deduction on charities donation revenue from charities tax filings a one percent increase in the tax cost of giving causes charitable receipts to fall by about four percent an effect three times larger the consensus in the literature further analysis reveals substantial heterogeneity in the tax response by subsector health care and home care are more tax sensitive than other charities while higher education and arts are less tax sensitive the results are consistent with substantial tax response heterogeneity within the sample and between sampled and unsampled charities implying that the mean tax elasticity of charitable contributions is a poor predictor of tax incentive effects for individual charities

migration remittances and male and female employment patterns little is known about the labor market impacts of workers remittances despite their magnitude in countries with considerable outmigration reports that families receiving international remittances severely curtail their work efforts are fairly common in the popular press e g robert frank 2001 yet we lack rigorous analyses of how male and female labor supplies respond to increases in remittance income to either support or refute these anecdotal observations according to the neoclassical model of labor leisure choice mark r killingsworth 1983 remittances a source of nonlabor income may lift budget constraints raise reservation wages and through an income effect reduce the employment likelihood and hours worked by remittance receiving individuals the receipt of remittances is usually preceded by the out migration of working aged household members however which may induce changes in the labor supply of nonmigrating household members in order to compensate for forgone income or to defray migration related expenses distinguishing the disruptive effect from the income effect of remittance inflows is problematic as most surveys do not contain detailed information on household outmigration and remittance receipt to the extent that these two effects are expected to have opposite impacts on labor supply however we can assess which effect dominates the impact of remittances on the decision to work has been previously examined by edgard rodriguez and erwin r tiongson 2001 in manila and by edward funkhouser 1992 in managua without accounting for the endogeneity of remittances with respect to labor supply they conclude that remittances reduce employment funkhouser also finds that remittances slightly increase self employment while informative these studies focus on the decision to work and do not consider that without altering employment rates remittances may change the hours worked and or the type of work performed in the receiving economy furthermore the impact may be different on male and female labor supplies and responsiveness to remittance income may vary from rural to urban areas using data from mexico a country with a large and growing remittance inflow we address the following questions how does the employment status and hours worked by men and women vary owing to international remittances do male and female labor supplies differ across various types of employment in rural versus urban areas due to higher remittance inflows

capital income taxation and perfect foresight abstract this paper develops a perfect foresight model of capital income taxation in a representative household neoclassical one sector framework the household sector is based on intertemporal utility maximization the main result is the equivalence of a perfect foresight solution and an artificial central planning solution if there is no tax this is the equivalence of a market equilibrium and social optinum the equivalence result is used to deduce the implications of a partial tax reform policy it is shown that a partial reform increases capital at each time following the initial period of the program

remittances in small island developing states abstract we examine how remittances relate to the exchange rate natural disasters and foreign aid focusing on small island developing states sids using panel var methods we are able to compensate for both data limitations and endogeneity issues while remittances respond to innovations in the macroeconomic variables included in the analysis remittances also have important impacts on these variables furthermore the impact of remittances differs in sids economies relative to the set of all developing economies remittances appear to depreciate the real exchange in sids economies whereas they appreciate the real exchange rate when a broader sample of economies is considered

exhaustibility and risk as asset class dimensions a social investor approach to capital resource economies this paper develops a framework in which asset class dimensions are extended to include both risk and exhaustibility for explaining the evolution of shadow prices of marginal units of exhaustible natural resources in capital resource economies it is shown that the pricing kernel function required for socially valuing marginal units of exhaustible resource hereafter called the exhaustion stochastic discount factor combines a factor that discounts for risk and another factor that discounts for resource exhaustion over time the social rate of return on the marginal unit of resource stock adds to the risk premium an exhaustion premium that accounts for the resource depletion over time in this setting the principle of no arbitrage holds by extending asset class dimensions to include not only a risk dimension but also an exhaustibility dimension

keeping one step ahead of the joneses status the distribution of wealth and long run growth assuming that the utility of each agent depends on its relative wealth position in the society this chapter constructs an endogenous growth model it is shown that even if the subjective discount rates differ across agents there exists a unique balanced growth equilibrium in which each agent owns a positive share of the world wealth it is also shown that if the agents are identical then an increase in savings incentives always raises the long run growth rate but if they are heterogeneous then an increase in savings incentives may lower the long run growth rate

remittances and economic growth larger impacts in smaller countries this paper examines the impact of remittances on economic growth in small island developing states sids results from variants of an empirical model suggest that while on average there is at best no association between remittances and growth in developing countries there is a positive association between these variables in sids this finding holds for sids in sub saharan africa and the pacific but not for those in latin america and the caribbean relationships between remittances economic volatility and household labour supply are offered as reasons for these findings

some causes are more equal than others the effect of similarity on substitution in charitable giving donation matching and other directed interventions to encourage prosocial contributions may affect contributions through other channels in an experimental dictator game where subjects may donate to two different real world charities we simulate activity specific interventions by varying the relative productivity of those charities and introduce several treatments to test whether i subjects substitute across charities and ii whether substitution occurs even across possibly very dissimilar alternatives we find that significant substitution occurs in all cases but that the effect is weaker the more dissimilar the charity alternatives in our most dissimilar treatment substitution is only half as large as when alternatives are very similar

luxury and wealth i develop a dynamic theory of luxury consumption particularly emphasizing the causal effect that pursuit of luxury goods has on wealth accumulation a quasi luxury is defined as a good whose marginal rate of substitution is increasing in a utility index under certain conditions it is indeed a luxury good when current wealth holding falls short of exceeds long run needs luxury consumption is postponed more less easily than necessity consumption due to a lower higher time preference for luxury and or a higher intertemporal elasticity of substitution thereof preferences for quasi luxuries lead to a higher steady state value of wealth or capital

remittance receipt and business ownership in the dominican republic using household level data from the dominican communities in the latin american migration project lamp dr7 we examine the links between remittance receipt and business ownership we find that while the existence of a family business attracts remittance inflows these monetary funds are associated with a reduced likelihood of business entrepreneurship these results are consistent with various hypotheses regarding remittances and business investments first remittances may be motivated by the availability of investment opportunities in the home community second remittances may respond to a bequest motive on the part of the emigrant who may wish to lay claim on family assets when returning home lastly remittances may cause an income effect that reduces family labour force participation and correspondingly the likelihood of family run business investments

impatience impoverishment and risk abstract a stochastic growth theory model is presented in which the less well off are impatient to consume but are also relatively less risk averse they can therefore maintain their consumption rates without eventually becoming impoverished unlike in the certainty case

do share of income limits on tax deductibility of charitable contributions affect giving abstract the 2017 tax cut and jobs act increased the limitation on the tax deductibility of charitable contributions from 50 to 60 percent of adjusted gross income this note estimates the effect of the share of income limitation on giving for the first time patterns in giving over time and across charities coincide with earlier changes in the share of income limit consistent with a substantial policy effect i estimate that the 2017 limit increase will boost aggregate household giving on the order of 10 billion

the effects of import quotas on national welfare reply gokcekus and tower 1997 argue that applying the friedman rule friedman 1969 instead of a consumption tax in our framework palivos and yip 1997a can also support the pareto optimal allocation for variants of the model the friedman rule is administratively simpler and may be welfare superior in this reply we argue that indeed in a dynamic version of our model the friedman rule is equivalent to a consumption tax for some variants of the model however the friedman rule is not administratively simple and may not result in pareto optimality

the impacts of international migration on remaining household members omnibus results from a migration lottery program this brief summarizes the results of a gender impact evaluation study entitled the impacts of international migration on remaining household members omnibus results from a migration lottery program conducted in 2002 in tonga the study observed the impact of migration lottery program on the remaining household members of tongan emigrants on the individual and intra household level income falls rapidly by 22 to 25 percent with a rise in remittances failing to offset a large fall in labor earnings ownership of livestock durable and access to financial services is lower for the remaining household members diets change to be less nutritious and more rice and root crops immigration has a negative impact on household size there is no significant impact of migration on labor supply for men nor women funding for the study derived from the world bank stanford university the waikato management school and mardsen fund

handle with care fragile states and the determinants of fragility the international community has grave concerns over the capacity of so called fragile states to effectively deliver basic services to their people due to their weak policy and institutional environments this article examines the drivers of state fragility the world bank and oecd definitions of fragility are adopted using the world bank s country policy and institutional assessment cpia scores analysis is conducted on both binary measures of fragility and the actual cpia scores using an array of estimation techniques findings indicate that democracy income levels economic growth levels of education country size and natural resource rents are important determinants of fragility unlike other studies findings also suggest that being a small island development state is a primary driver of fragility

empirical evidence of news about future prospects in the risk pricing of oil assets abstract this empirical paper investigates the relevance of long run risks associated with uncertainty shocks to future growth prospects news about future prospects for explaining the risk pricing of oil stocks an econometric method that incorporates dynamic factor analysis is used for estimating the pricing equation of oil stocks the results indicate that oil investors care about long run risks associated with future growth prospects long run risks account for almost half of the total risk premium of oil stocks long run risks associated with future growth prospects are significantly shaped by latent factors related to the labor market the price indices and financial markets moreover our estimated model captures some historical events including the oil crisis of the seventies the economic crisis of the mid eighties the stock market crash of 1987 and the economic crises of 1998 and 2000

weakly non separable preferences and the harberger laursen metzler effect we examine the current account effect of a terms of trade deterioration for a small country model incorporating weakly non separable preferences a la shi 1994 under endogenous time preference this enables us to emphasize a welfare change as an important determinant of the current account even with increasing marginal impatience the harberger laursen metzler effect occurs if consumers preference toward imports is sufficiently wealth enhanced in that case a terms of trade deterioration must reduce steady state welfare to shift preference away from imports to exports several empirical implications are also derived jel classification f41 f32 preferences faiblement nonseparables et l effet de harberger laursen metzler l auteur examine l effet sur le compte courant d une deterioration des termes d echange dans un modele d un petit pays quand les preferences sont faiblement nonseparables a la shi 1994 et que la preference temporelle est endogene cela permet de souligner qu un changement dans le niveau de bien etre est un determinant important du compte courant contrairement a ce qu on trouve dans la litterature specialisee meme quand on postule une impatience marginale croissante l effet harberger laursen metzler se produit si la preference des consommateurs pour les importations est suffisamment dependante du niveau de richesse dans ce cas la une deterioration des termes d echange doit reduire le niveau de bien etre en regime permanent de maniere a deplacer les preferences des importations vers les exportations on deduit certaines implications empiriques de ces resultats

on the rate of time preference under recursive preferences abstract the boehm bawerkian and the fisherian approaches lead to identical measurements on both the strong and the weak rates of time preference since they are generally path dependent when goods are multiple conditions assuring their path independence are identified

workers remittances and the real exchange rate a paradox of gifts abstract we test the impact of workers remittances on the real exchange rate using a panel of 13 latin american and caribbean countries the analysis reveals that workers remittances have the potential to inflict economic costs on the export sector of receiving countries by reducing its international competitiveness our findings raise concerns parallel to those raised by dutch disease or resource boom models where resource discoveries result in real exchange rate appreciation and shifting of resources from the traded to the nontraded sectors of the economy

safety first consumption abstract this paper develops a model of safety first consumption behavior in which the likelihood of survival to the next period depends on current consumption levels below a threshold asset level individuals follow a decumulation path and above that level they follow an accumulation path saving rates then vary discontinuously with asset level generating a poverty trap and divergence in incomes an increase in the likelihood of surviving raises aggregate saving a more equitable distribution of assets can be consistent with greater aggregate savings and growth because of declining marginal propensity to save over some asset intervals

the derivation of discount rates with an augmented measure of income abstract most developed economies invest in public goods such as national defense education infrastructure and the environment discount rates used to evaluate such projects should reflect the rate of return on the current mix of investment opportunities rates derived from the productivity of private capital neglect returns beyond the market boundary the present paper derives discount rates using an augmented measure of national income inclusive of non market goods in an empirical application focusing on air pollution and climate damages in the united states economy the paper reports that the difference between augmented and market discount rates averages 0 3 percentage points from 1999 to 2014

impatience and long run growth abstract this contribution is concerned with the possibility of a perpetual growth path at increasing rates in a nonconvex optimal growth model with endogenous discounting sufficient conditions for the existence of this path can be established when the economy is populated by agents whose impatience does not increase too much along the course of a consumption path in the opposite case the dynamical system is asymptotically described by a steady state however this steady state position need not be uniquely defined saddlepoint equilibria and locally oscillating unstable equilibria may alternate in spite of increasingly impatient agents along the growth process it remains optimal for a government to subsidize the competitive economy under a razor edge assumption on impatience a growing planning solution may coexist with a stationary competitive solution

decreasing and increasing marginal impatience and the terms of trade in an interdependent world economy abstract using a two good two country model we examine macroeconomic adjustment by allowing for decreasing and increasing marginal impatience dmi and imi in the reference case where both countries have imi a negative output shock in one country lowers the interest rate and both countries welfare levels in steady state whereas when either one country has dmi the negative income shock raises the interest rate thereby benefiting the imi country and harming the dmi one in steady state in a country either with imi or dmi the harberger laursen metzler effect takes place if negative welfare supporting effects dominate positive income compensating effects

migration networks and microenterprises in mexico are migration networks associated with lower capital costs or the alleviation of capital constraints we examine these questions with data measuring access to remittance flows among small scale entrepreneurs in mexico using a survey of more than 6000 self employed workers and small firm owners located in 44 urban areas of mexico we estimate the impact of attachment to migration networks on the level of capital investment the capital output ratio sales and profits of microenterprises the impact is identified from the geographic pattern of migration from mexico driven by the completion of rail lines in the early 1900s for the full sample of firms we find that migration is associated with higher investment levels and higher profits but not higher sales the strongest effects on investment are in the categories of automobiles tools and inventories when the sample is limited to firms in high capital sectors investment sales and profits all increase with attachment to the migration networks suggesting that attachment to the migration network alleviates capital constraints in those sectors

migrant remittances and fertility abstractthis study examines the role of migrants remittances in developing countries fertility transition employing an unbalanced panel of south asian countries and controlling for various economic and socio demographic factors we find that remittances are significantly associated with a lower number of children born to women of childbearing age this suggests the remittances substitution effect to be at play rather than the income effect and may result from decreased need for children for financing the household s future needs as well as from better access to healthcare and contraceptive methods available to migrant households remittances association with fertility appears to be more important than the transfer of fertility norms from migrants host countries the monetary aspects of international migration may therefore be more important for the region s demographic transition than social remittances

myopia and addictive behaviour we present a theory of addictive behaviour which can account for addicts apparent disregard for the future consequences of their current actions the discounting of future utility is increasing in past consumption indicating increasingly myopic behaviour as consumption increases the intertemporal complementarity generated by the endogenous discounting produces multiple steady states which can account for the simultaneous existence of myopic addicts and non myopic non addicts within a time consiste nt expected utility framework the theory also accounts for the probabilistic incidence of addiction and successful rehabilitation and the possibility of recurrence

intertemporal dependence impatience and dynamics abstract this paper develops simple geometric methods for analyzing consumer behavior under recursive but intertemporally dependent tastes since the preferences studied need not be time additive they allow the marginal utility of consumption on a given date to vary with consumption on other dates intertemporal dependence is induced by the presence of a variable individual rate of time preference the optimal consumption responses to transitory and anticipated changes in incomes and interest rates are easily derived and are similar in many respects to the responses implied by the standard constant time preference model intuitive explanations of the first order conditions describing optimal paths are provided

tax incidence in a two sector growing economy with perfect foresight abstract the purpose of this paper is to re examine the long run incidence of taxation in so doing we shall employ a two sector perfect foresight equilibrium model with either a constant and variable discount rate in the former a change in a personal income tax or any selective tax e g a commodity payroll or profit tax on the investment goods sector affects either the factor price or factor income ratio all selective taxes on the consumption goods sector are neutral in the sense that they do not affect either ratio in the latter only the commodity tax on the consumption goods is still neutral

on impatience economic growth and the environmental kuznets curve a dynamic analysis of resource management the paper presents a dynamic analysis of natural resource management and investigates some key factors that affect optimal management and resource conservation using a recursive specification of time preferences we show how endogenous discounting and impatience can affect the motivation for both capital investments and environmental preservation we examine the relationships between economic growth and environmental quality endogenous discounting provides new insights in the economic dynamics underlying the environmental kuznets curve by treating growth as endogenous we examine how externalities and economic growth interact with each other we investigate how economic development can contribute to an increased demand for environmental preservation as an important new result we also show how poverty can contribute to environmental degradation

recursive preferences and balanced growth abstract we study a class of utility functions that are defined recursively by an aggregator w x y where u t w c t u t 1 in single agent economies it is known that a sufficient condition for the existence of a balanced growth path is that utility should be homogenous of degree in the context of a multi agent economy we show that this restriction implies that either a balanced growth equilibrium fails to exist or all agents have the same constant discount factor we suggest a generalization of recursive preferences wherein the intertemporal utility function is time dependent within this class we establish that there may exist a balanced growth equilibrium even if agents are different

the recursive core core allocations may be defined for infinite horizon capital accumulation models if agents cannot trust each other in the sense of gale then agents may renege on their commitments their decisions appear time inconsistent a core allocation is a recursive core allocation provided no coalition can improve upon its consumption stream at any time given its accumulation of assets up to that period we show for every allocation of consumption in the initial core one can find a distribution of capital stocks among the agents where no coalition of agents will break the initial core contract at any date it follows that if the proper distribution of the streams of capital is achieved then the allocation in the core is also in the recursive core the latter therefore forges a link between the distribution of wealth capital the problem of trust and time consistent intertemporal contracts

optimal redistributive capital taxation in a neoclassical growth model abstract this paper provides a counterexample to the simplest version of the redistribution models considered by judd 1985 in which the government chooses an optimal distortionary tax on capitalists to finance a lump sum payment to workers i show that the steady state optimal tax on capital income is generally non zero when the capitalists utility is logarithmic and the government faces a balanced budget constraint with log utility agents optimal decisions depend solely on the current rate of return not any future rates of return or tax rates this feature of the economy effectively deprives the government of a useful policy instrument because promises about future tax rates can no longer influence current allocations when combined with a lack of other suitable policy instruments such as government bonds the result is an inability to decentralize the allocations that are consistent with a zero limiting capital tax i show that the standard approach to solving the dynamic optimal tax problem yields the wrong answer in this knife edge case because it fails to properly enforce the constraints associated with the competitive equilibrium specifically the standard approach lets in an additional policy instrument through the back door
