country portfolios under global imbalances abstract this paper studies the composition of country portfolios under global imbalances when countries are identical the optimal portfolio is fully diversified which reflects the cross country symmetric self hedging lucas 1982 assuming a structural country asymmetry in patience we construct a model of portfolio choices that features persistent non zero net foreign assets nfa because the latter opens a gap between gnp and gdp we found that an asymmetric hedging of net portfolio returns emerges in addition to the otherwise only lucas symmetric self hedging in shaping the gross country portfolios which implies a short long position of the local asset in the debtor creditor country the resulting portfolio is home biased we calibrate our model to the u s and china data over 1999 2017 and show that it matches the portfolio data for countries with unbalanced net external positions well

democracy creeping socialism and ideological socialism in rent seeking societies rent seeking societies suffer from a serious distortion of incentives incentives to engage in distributional struggles to seek contrived transfers are strong but incentives to engage in productive work are too weak stagnation and some unemployment should be expected long lasting democracies within unchanged borders create a permissive environment for rent seeking the provision of rents very much depends on government the stronger the governmental involvement in the economy the higher social security spending the more rents the government is likely to generate therefore creeping socialism understood as increased government control of the economy should reinforce the rent seeking society and the corresponding negative effects on growth and employment whether such creeping socialism is backed by ideological socialism or not should make little difference for growth or employment these ideas have been tested and partially supported by a 19 nation sample of industrial democracies using data from the sixties and seventies by and large the rent seeking approach is fairly successful in explaining national differences in economic growth rates but receives ambiguous support or less for unemployment olson s 1982 1983 proposition about the negative impact of long lasting democracy within unchanged borders on economic growth is much better supported than the growth retarding effects of government revenues or social security spending are

public health spending old age productivity and economic growth chaotic cycles under perfect foresight abstract this paper analyses the dynamics of a double cobb douglas economy with overlapping generations and public health investments that affect the supply of efficient labour of the old aged it is shown that the positive steady state of the economy is unique moreover we provide necessary and sufficient conditions for the emergence of endogenous deterministic complex cycles when individuals are perfectly foresighted interestingly i the equilibrium dynamics shows rather complicated phenomena such as a multiplicity of bubblings depending on the size of the public health system and ii the higher the degree of thriftiness the likelier an economy is exposed to endogenous fluctuations because the need to save when young to support consumption when old is reduced

dynamic efficiency in overlapping generations models with stochastic production abstract we consider an overlapping generations economy as in diamond amer econ rev 55 1965 1126 1150 with stochastic production we define two types of efficiency for feasible production consumption allocations using first and second degree stochastic dominance we obtain a complete characterization of inefficiency of type i in this model for each given sequence of strictly concave utility functions for all generations the existence of a competitive equilibrium is proved it is shown that each competitive allocation is short run efficient of type ii

impact of pension system structure on international financial capital allocation abstract recent findings indicate that pension system structure affects private savings and through them the aggregate foreign asset position of a country we present a two country overlapping generations model that explores the relationship between the magnitude of pension guarantees and the resulting portfolio choices of workers the existence of a pay as you go pension system lowers the wealth of the young workers who consequently borrow from abroad to supplement their current consumption and lowers the overall riskiness of their lifetime wealth prompting them to invest in risky equity financed by the selling of safe bonds in particular we are able to replicate and explain the venture capitalist positive net equity accompanied by negative net debt portfolio profile of the united states more broadly we find empirical support for our results in a cross country analysis using data from 110 economies greater amounts of pension spending are associated with international indebtedness long equity positions and short debt positions

the productivity puzzle abstract the productivity puzzle is the unexplained drop in productivity growth rates that began circa 1970 when standard productivity measures are adjusted for employer incentives for labor hoarding approximately 10 of this drop is explained

time preference and international lending and borrowing in an overlapping generations model two economies represented by diamond type overlapping generations models and differing only in their pure rates of time preference are joined together capital formation balance of payments behavior and welfare are compared under autarky and openness with a positive natural rate of growth the low time preference country runs a current account surplus in the steady state but not necessarily outside it if preexisting capital is not shiftable between countries integration in the world economy makes the high time preference country worse off in the short run the ranking of stationary utility levels under autarky and openness is ambiguous

tests of a rational theory of the size of government in many countries the political party holding power changes more frequently than the trend growth rates in government spending and taxes shifts of political power are often preceded by rhetoric about meeting needs or cutting taxes which post election performances rarely match yet changes in the size of government up and down occur on average the size of government measured by the share of taxes or spending to output has increased in many countries during the past century but changes in size occur at diffrent rates and at times the relative size of government declines

expenditures and receipts testing for causality in state and local government finances the results of our tests indicate similarities between the expenditure tax receipt relations of state governments to those previously reported for the federal government in manage and marlow 1986 the results reported here indicate support for the hypothesis that tax receipts cause expenditures at the state level of government for tests utilizing symmetric lag structures ranging from three to five years state expenditures appear to follow state tax receipts for the shortest lag length 2 2 the determination of bidirectional causality does not make us reject the hypothesis that higher spending levels result from higher revenue levels rather the causality appears to be in both directions for the shortest lag length

the transfer paradox in a one sector overlapping generations model abstract this paper examines the effects of international income transfers on capital accumulation and welfare in a one sector overlapping generations model it is shown that a strong form of the transfer paradox in which the donor country experiences a welfare gain while the recipient country experiences a welfare loss may occur both in and out of steady state in addition it is shown that a weak form of the transfer paradox where either the donor or recipient but not both experiences a paradoxical welfare effect may characterize all segments of the transition path not already characterized by the strong transfer paradox

state responses to fiscal crises the effects of budgetary institutions and politics this paper explores the dynamics of state taxes and spending during the late 1980s when regional economic downturns and increased expenditure demands led to substantial state budget deficits more restrictive state fiscal institutions such as no deficit carryover rules and tax and expenditure limitations are correlated with more rapid fiscal adjustment to unexpected deficits political factors are also important when a single party controls the state house and the governorship deficit adjustment is much faster than when party control is divided in gubernatorial election years tax increases and spending cuts are both significantly smaller than at other times

determinacy of equilibrium in stationary economies with both finite and infinite lived consumers abstract we consider the determinacy of perfect foresight equilibrium near steady state equilibria of stationary infinite horizon economies the work of t j kehoe and d k levine econometrica 53 1985 433 453 is generalized by the inclusion of both infinite lived agents and overlapping generations of finite lived agents and the inclusion of production and non depreciating pure rents we show that indeterminacy is possible in robust examples and that the dimension of the indeterminacy can be as large as the number of goods per period we also discuss extreme cases in which determinacy is guaranteed

modeling the experimentally organized economy complex dynamics in an empirical micro macro model of endogenous economic growth abstract the swedish micro to macro model moses is used to show how complex economic behavior emerges from interacting boundedly rational agents the simulation model has been calibrated using business firm data non linearities arise in its specification of technology the distribution of firm characteristics and in the rules that govern entry and exit the model economy is characterized by a restless competitive growth process that is normally robust but that now and then generates phases of local disorderly behavior including for some parameter settings the collapse of entire sectors the model explains why government agents have difficulty predicting the reactions of the economy to policies suggesting that government treads cautiously in order not to do more harm than good

capture and ideology in the economic theory of politics the economic theory of regulation long ago put public interest theories of politics to rest these theories have correctly been viewed as normative wishings rather than explanations of real world phenomena they have been replaced by models of political behavior that are consistent with the rest of microeconomics anthony downs 1957 james buchanan and gordon tullock 1965 george stigler 1971 sam peltzman 1976 recently however debate has arisen over whether some version of a public interest theory of regulation will have to be readmitted to our thinking about actions and results in the political arena what is at issue is the empirical importance of the altruistic publicly interested goals of rational actors in determining legislative and regulatory outcomes james kau and paul rubin 1979 kalt 1981 peltzman 1982 this study assesses the nature and significance of publicly interested objectives in a particular instance of economic policymaking u s senate voting on coal strip mining regulations the existence of such objectives is of course no contradiction of the economic view of human behavior kenneth arrow 1972 gary becker 1974 and may well be rooted in genetic biological history becker 1976 jack hirshleifer 1978 generally however individuals altruistic publicly interested goals have been given little attention this reflects the judgment that such goals are so empirically unimportant as to allow the use of occam s razor in positive models or well founded apprehensions that these goals are unusually difficult to identify measure and analyze notwithstanding the latter problem we find that approaches which confine themselves to a view of political actors as narrowly egocentric maximizers explain and predict legislative outcomes poorly the tracking and dissecting of the determinants of voting on coal strip mining policy suggest that the economic theory of politics has been prematurely closed to a broader conception of political behavior

stochastic olg models market structure and optimality for a general class of pure exchange olg economies under uncertainty we provide a complete characterization of the efficency properties of competitive equilibria when markets are only sequentially complete and the criterion of efficency is conditional pareto optimality we also consider a particular case in which markets fail to be even sequentially complete and provide a characterization when the criterion of efficency is weakened to ex post pareto optimality

the effect of property tax limitation measures on local government fiscal behavior abstract previous evidence on the effects of tax and expenditure limitation measures has not been conclusive difficulties arise in characterizing differences in fiscal institutions across states and estimating behavior in the absence of limitation measures a recently enacted tax limitation measure limits the growth in local property taxes in some illinois jurisdictions but not in others such differential treatment of otherwise similar jurisdictions provides a natural experiment for estimating the impact of the tax cap on local government fiscal behavior we find that the cap has been effective in that the fiscal behavior of capped jurisdictions differs from that of never capped jurisdictions

increasing returns and crowding out abstract this paper explores how public debt interferes with the accumulation of physical capital when the technology displays a production externality of the arrow romer type we identify conditions under which a small positive amount of debt will prevent the economy from ever approaching the stock of capital that it would achieve if public debt were zero we also show that the interaction of debt and production externalities may produce bounded possibly cycling capital stock sequences in economies where sustained growth rates are possible with zero national debt finally welfare issues concerning the relation between static and dynamic inefficiencies are discussed

the savings multiplier we develop a theory of macroeconomic development based on the novel concept of savings multiplier capital accumulation changes relative prices and income shares between generations creating further incentives to accumulate and thereby rising saving rates as the economy develops the savings multiplier hinges on two mechanisms first accumulation raises wages and leads to redistribution from the consuming old to the saving young second higher wages raise the price of services consumed by the old and the anticipation of such price rise prompts the young to increase their savings our theory captures important aspects of china s development and suggests new channels through which the one child policy and the dismantling of cradle to grave social benefits have fuelled china s savings and accumulation rates

search unemployment in an overlapping generations setting this paper constructs an overlapping generations model in which the steady state equilibrium is characterized by the existence of search unemployment this dynamic general equilibrium model captures the possible existence of search unemployment in the long run despite the absence of exogenous shocks furthermore it allows for the wage offers distribution to be determined endogenously the effect of partial revelation of information on the existence of search unemployment in the long run is examined it is shown that search unemployment may be eliminated in the long run despite the persistence of the state of imperfect information this paper develops an overlapping generations model in which the steady state equilibrium is characterized by search unemployment 2 unemployment is created via a rational rejection of available wage offers in favor of further search for potentially more attractive offers the proposed dynamic general equilibrium model allows for the existence of long run search unemployment despite the absence of exogenous shocks and permits the presence of an endogenously determined nondegenerate wage offer distribution 3 the paper analyzes the trade off between revelation of information and the level of search unemployment in the long run in the absence of external disturbances the level of search unemployment would be expected to decrease as information becomes available in particular if information is fully revealed search unemployment is naturally eliminated exploring the likelihood of the existence of long run search unemployment in a deterministic world this study provides an example of partial revelation of information which eliminates search unemployment in the long run despite the persistence of the state of imperfect information 4 the proposed model presents a discrete infinite time horizon world where economic activity is conducted under imperfect information in every period a single homogeneous good is produced using two factors capital and labor in the production process the aggregate endowment of labor is exogenously given in

a critique on the effectiveness of tax expenditure limitations the principal purpose of this study is to investigate the probable impact of tax and spending limitations on tax burdens and state expenditures this is accomplished via a systematic evaluation of the alternative proposals associated with tax limitation legislation in particular this paper analyzes the linking of state public sector growth to inflation limiting tax burdens to a percent of personal income the inclusion of escape clauses in the enabling legislation and the evolution of these tax limitations into legalized minimums

an olg model of global imbalances in this paper we investigate the relationship between east asian countries high propensity to save and global imbalances in a two country olg model with production the saving behavior of emerging economies and capital outflows to the united states can be attributed to their poor pay as you go systems the model predicts that emerging countries run a trade surplus only as long as the long run growth rate of the economy is higher than the real interest rate capital overaccumulation case the low real interest rate in the us is therefore evidence in favor of the hypothesis that there is a global saving glut in the world economy the model can explain why the us current account deteriorated gradually and only in the late 1990s although the net foreign asset position had already turned negative in the early 1980s finally the analysis also implies that an improvement of the pay as you go system in china would have the effect of reducing the imbalances in accordance with the theory we find that the higher is the percentage of the working population covered by the pay as you go system the lower are savings and the current account balance in a cross section of countries

do budget maximizing public officials increase the probability of property reassessment county governments in pennsylvania face non binding limits on their property tax rates these are considered non binding because they do not place a limit on tax levies or expenditures assuming local public officials have monopoly power tax rate limits can be circumvented by reassessing the property tax base a two stage process was hypothesized in which the probability of reaching tax rate limits first was determined and the probability of reassessment then was determined the effect of budget maximizing government officials at each stage was tested for 66 pennsylvania counties over the 1970 1995 period the empirical results showed that variables associated with budget maximizing behaviour influenced the choice in each stage public expenditure growth increased the probability of reaching the tax rate limit in the first stage while reaching the tax rate limit increased the probability of reassessment in the second stage the estimates also showed that economic fiscal and taste variables were signific

the relationship between on budget and off budget government abstract this paper studies the hypothesis that controls on on budget government spending leads to greater off budget activity existence of a substitution effect suggests that our ability to control and measure the size of government is more difficult than previously thought

optimality in stochastic olg models theory for tests we consider general olg economies under uncertainty with short maturity assets and with dividend paying assets of infinite maturity and fiat money and study the optimality properties of equilibria with a sequence of asset markets that are sequentially complete we provide necessary and sufficient conditions in terms of asset prices and dividends for equilibria to be conditionally pareto optimal these results provide a theoretical basis for empirical investigation

the cass criterion the net dividend criterion and optimality abstract abel mankiw summers and zeckhauser assessing dynamic efficiency theory and evidence rev econ stud 56 1989 1 20 propose the net dividend criterion as an easy to use sufficient condition for optimality in general stochastic overlapping generations economies with production we provide examples based on the criterion due to cass on capital overaccumulation in the aggregative neoclassical model of economic growth a complete characterization j econ theory 4 1972 200 223 and its extensions the usual tools for such problems to show that the net dividend criterion need not give the right answer we identify the flaw in their proof we also provide an alternative condition which by an argument unrelated to theirs is a sufficient condition for optimality when dividends are nonnegative and then argue that the condition is not innocuous since it cannot be verified in actual economies

a rent seeking model of tels tax and expenditure limits or tels are constitutional or statutory constraints on the fiscal powers of government since the taxpayer revolt beginning in the late 1970s tels have been introduced in twenty three states in recent years a number of studies attempting to test the impact of tels have found little evidence that tels significantly reduced the growth of state government in this study we challenge the implicit leviathan model that underlies most of these studies and offer an alternative rent seeking model econometric tests provide support for this rentseeking model and indicate that tels have been significant in reducing the growth of state government at least in the short run

controlling leviathan through tax reduction our paper seeks the strategy that allows the greatest ability to reduce public sector size within a political environment that does not want us to directly set limits on public sector size tax reduction through its quid pro quo effect offers high tangibility to taxpayers and may raise political power of groups that seek both tax reduction and greater opposition to lobbies that seek spending increases for their narrowly defined interests moreover as manage and marlow 1986 argues since the political response to balanced budget rules is likely to raise taxes this political bias of tax hikes suggests that balanced budget rules are offered as a means of changing the funding mix and not the actual budget constraint of government

the emergence of chaos from classical economic growth this paper shows how fluctuations of an erratic and unstable nature can emerge from the classical deterministic economic growth process implications of the analysis would appear to be at least two first pronounced changes in the way an economy behaves need not cause us to reject our understanding of how it works second we need not seek in exogenous forces an explanation as to why behavioral patterns change and why it may be so difficult to anticipate future events from the profile of past experience

micro heterogeneity of firms and the stability of industrial growth abstract in the micro macro m m model moses real swedish firms make independent decisions in markets schumpeterian innovative activities and wicksellian capital market disequilibria generate a growth cycle production and investment decisions in firms are dynamically coordinated by markets for products labor and capital under different market regimes as to speed intensity of competitive processes and of innovative activity by varying market regime ceteris par leux long term growth rates of the economy can be generated at cliffe as much as between the industrial countries during the last 50 years high speed market processes increase output growth for long periods but make the model economy sensitive to disturbances that eventually generate a severe depression simulation results suggest the importance for stable macroeconomic growth of a steady input of innovative technical change through new investment new entry and exit to preserve micro diversity of structures

disequilibrium economic dynamics a post schumpeterian contribution abstract adaptive economizing in a decentralized economy with alternative technologies and scarce resources leads to various kinds of locally unstable behavior economic disequilibrium is the rule in such a world and requires the presence of market mechanisms that make possible continued viability if in addition to local instability economies are also globally unstable as considerable evidence suggests then the discovery and application of new structure is essential a complete dynamic theory of economic change must therefore be based not only on conventional rationality and routinely adapting behavior but on a superior faculty which may perhaps best be called creative intelligence

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

temporary and permanent migration with and without an immobile factor abstract this paper develops two two country overlapping generations models one with and one without an immobile factor to study temporary and permanent migration temporary migration is shown to be equivalent to international lending and borrowing one strong result found in the literature that if natives of each country are homogeneous permanent migration leads to the migration of the entire population of the impatient country in the long run is overturned welfare effects of migration are analyzed

some evidence on the effect of the separation of spending and taxing decisions it is often argued that separation of public spending and taxing decisions engenders in the voter overoptimistic hopes that someone else will bear the cost of public services thereby inducing an increase in the size of government but are perceived tax prices systematically and persistently reduced by separation although in stock markets all agents expectations may be unbiased they may or may not be unbiased in political markets this paper analyzes the separation created in federal states when the central government finances local expenditures evidence from a dynamic decisive voter model is presented that indicates that the separation introduced by federal grants to canadian provinces did in fact reduce the perceived tax price of provincial public services and raise provincial expenditures the results suggest also that the effect of separation diminished over time

asset prices debt constraints and inefficiency abstract we consider possibly non stationary economies with endogenous solvency constraints under uncertainty over an infinite horizon as in alvarez and jermann 2000 5 a sort of cass criterion cass 1972 10 completely characterizes constrained inefficiency under the hypothesis of uniform gains from risk sharing which is always satisfied in stationary economies when the autarchy is constrained inefficient uniform gains from risk sharing also guarantee a finite value of the intertemporal aggregate endowment at a constrained optimum hence no equilibrium exhibits a null interest rate in the long run finally constrained inefficiency occurs if and only if there exists a feasible redistribution producing a welfare improvement at all contingencies

an evolutionary approach to understanding international business activity the co evolution of mnes and the institutional environment this paper examines the co evolution of mne activities and institutions external and internal to the firm we develop a theoretical framework for this analysis that draws on the more recent writings of douglass north on institutions as a response to complex forms of uncertainty associated with the rise in global economic interconnectedness and of richard nelson on the co evolution of technology and institutions we link historical changes in the character of mne activities to changes in the institutional environment and highlight the scope for firm level creativity and institutional entrepreneurship that may lead to co evolution with the environment we argue that the main drivers for institutional entrepreneurship are now found in the increasing autonomy of mne subsidiaries thus mne agency derives from more decentralized forms of experimentation in international corporate networks which competence creating nodes of new initiatives can co evolve with local institutions unlike most other streams of related literature our approach connects patterns of institutional change in wider business systems with more micro processes of variety generation and experimentation within and across individual firms this form of co evolutionary analysis is increasingly important to understanding the interrelationships between mne activities and public policy

comparative statics and perfect foresight in infinite horizon economies does a pure exchange economy with an infinite time horizon have determinate perfect foresight equilibria when there is a finite number of infinitely lived agents equilibria are generically determinate this is not true with overlapping generations of finitely lived agents we ask whether the initial conditions together with the requirement of convergence to a steady state locally determine an equilibrium price path in this framework there are many economies with isolated equilibria many with continua of equilibria and many with no equilibria at all with two or more goods in every period not only can the price level be indeterminate but relative prices as well furthermore such indeterminacy can occur whether or not there is fiat money and whether or not the equilibria are pareto efficient this paper considers whether infinite horizon economies have determinate perfect foresight equilibria this question is of crucial importance if instead equilibria are locally indeterminate not only are we unable to make comparative static predictions but the agents in the model are unable to determine the consequences of unanticipated shocks the idea underlying perfect foresight is that agents expectations should be the actual future sequence predicted by the model if the model does not make determinate predictions the concept of perfect foresight is meaningless we consider two extreme cases the first with a finite number of infinitely lived consumers and the second with an infinite number of finitely lived consumers an overlapping generations model both are models of stationary pure exchange economies no production including the storage of goods between periods can occur these models are unrealistic but are the easiest to study extensions of the results of this paper to models with production infinitely lived assets and mixtures of the two types of consumers are presented by muller and woodford 29 when there is a finite number of infinitely lived consumers we argue that equilibria are generically determinate this is because the effective number of equations determining equilibria is not infinite but equal to the number of agents minus one and must determine the marginal utility of income for all but one agent generically near an equilibrium these equations are independent and exactly determine the unknowns when there are infinitely many overlapping generations this reasoning breaks down an infinite number of equations is not necessarily sufficient to determine

rent seeking from a property rights perspective james buchanan 15 15 has suggested that rent seeking analysis can readily be incorporated within the property rights approach and as with public choice the theory of rent seeking can be interpreted as an appropriate extension yet no one has really explored rent seeking or revenue premium tariff or directly unproductive profit seeking from a property rights perspective buchanan 14 15 16 17 clearly indicated that property rights assignments actually underlie the rent seeking process and others have also recognized this 4 20 23 28 but there are further insights into the workings of the political economy which can be derived for instance lobbying activities with nonpecuniary goals clearly fit into the rent seeking framework when viewed through the property rights paradigm this contrasts strikingly with the perception of rent seeking held by some writers 9 10 11 12 13 furthermore a property rights approach to rent seeking provides predictions of a spiraling process of government growth since successful rent seeking by one interest group generally requires expansion of bureaucratic powers while at the same time creating incentives for the formation of additional rent seeking interest groups legislative responses to these new groups requires further expansion of the bureaucracy and creates incentives for more rent seeking so the growth process continues in this paper a brief summary of the conclusions of the rent seeking literature will be presented followed by an explanation of how the same conclusions have been deduced using the property rights paradigm various extensions of the rent seeking concept such as those alluded to above are then obtained by emphasizing a property rights approach following this the terms used to describe rent seeking e g directly unproductive profit seeking etc will be discussed to determine which if any is the most appropriate characterization of the phenomenon

a positive model of tax structure the model of tax structure developed in this paper is one in which the composition of revenues and the structure of specific taxes arise naturally as the result of self interested political behavior it is assumed that political agents choose tax structure so as to minimize the political costs or expected net loss in votes associated with raising a budget of given size several hypotheses concerning the nature of political cost functions are developed and applied to an explanation of the differences among u s states in their reliance on income taxation the empirical application emphasizes differences in political constraints across jurisdictions in the belief that much can be learned about the choice of policy instruments by studying structural adjustments in response to varying constraints the paper discusses how the proposed approach differs from or is consistent with that adopted by other authors and how the estimating equation relates to other empirical research in the literature

from plan to markets abstract while formerly planned economies lack critical institutions ailing welfare economies have too many reducing investment incentives in both while institutional redesign is urgent in the formerly planned economies there is no instant concern in the west where institutional change must be realized through reluctant democratic procedures some formerly planned economies therefore are likely to improve upon the west in institutional design and experience superior long run economic growth they explicitly link investment incentives one way to property rights and the other to investment and growth to demonstrate how such superior performance can be achieved

existence uniqueness and stability of equilibrium in an overlapping generations model with productive capital abstract this paper analyzes the existence uniqueness and stability of a steady state equilibrium in an overlapping generations model with productive capital it is shown that for any feasible set of well behaved preferences there exists a production function that satisfies the inada conditions under which the economy experiences global contraction and the steady state equilibrium is characterized by the absence of production and consumption the study establishes a strengthened inada condition which is necessary to preclude global contraction and sufficient conditions for the existence of a unique and globally stable non trivial steady state equilibrium

an empirical analysis of state and local tax structure in the context of the leviathan model of government this paper has investigated the ability of an extreme and relatively simple model of political behavior to explain the level of revenues generated by state and local governments in general the behavior of these governments appears to be at least consistent with many of the fiscal outcomes predicted by the leviathan theory several although not all of the specific leviathan theory hypotheses considered received empirical support the evidence was consistent with the hypothesis that states utilizing comprehensive tax bases especially a personal income tax can be expected to generate higher levels of aggregate revenues strong support was also observed for the contention that intergovernmental competition by general purpose substate governments may serve as a substitute for constitutional constraints in limiting the revenue generating power of local governments

modeling the labor market as an evolving institution model artemis abstract a stylized french labor market is modeled as an endogenously evolving institution boundedly rational firms and individuals strive to decrease costs or increase utility the labor market is coordinated by a search process and decentralized setting of hiring standards but intermediaries can speed up matching the model reproduces the dynamics of the gross flows and the spectacular changes in mobility patterns of some demographic groups when the oil crisis in the 1970s occurred notably the sudden decline of the integration in good jobs the internal labor markets ilm of large firms are shown to increase unemployment if the secondary temporary or bad jobs do not exist

learning through short run macroeconomic forecasts in a micro to macro model abstract firms in the swedish micro to macro model moses learn about their environment through internal adaptive expectations and through short run external forecasts produced by statistical bureaus the statistical bureaus apply different macroeconomic models that they estimate on data generated by moses firms are learning about their degree of trust in the forecasts of statistical bureaus using bayesian rules in our experiments with learning through external forecasts firms are either forced to use only one source of macroeconomic information or allowed to choose between them with these experiments we can simulate a more or less centrally controlled economy experiments demonstrate that the more of variety of sources of information allowed the better macroeconomic performance

on the interaction between risk sharing and capital accumulation in a stochastic olg model with production abstract we analyze the interaction between risk sharing and capital accumulation in a stochastic olg model with production we give a complete characterization of interim pareto optimal competitive equilibrium allocations furthermore we provide tests of pareto optimality suboptimality based on risky rates of return only

will you marry me a perspective on the gender gap abstract this paper develops a general equilibrium model of the gender wage gap the difference in earnings is a consequence of a demographic regularity that men tend to marry younger women which may limit women s labor mobility and hence their average earnings however couples are always free not to marry and do so only if it is in each s self interest the intrafamily allocation of resources is determined via non cooperative bargaining this leads to interesting interactions between the game played by husband and wife on the one hand and the competitive environment in which they are immersed on the other the predictions resulting from this model s interplay between locational choice and family bargaining are consistent with the observation that the increasing stress put by women on their careers over the past 30 years has been contemporaneous with reductions in both marriage rates and the gender gap the model provides insight into the consequences of this for the relative welfare of men and women as well as exploring its wider economic implications

could prometheus be bound again a contribution to the convergence controversy abstract this paper presents a neoclassical model of stochastic growth in which the probability of adverse shocks to production is inversely related to the aggregate stock of capital per capita postulating this endogenous relationship justified by empirical evidence the model yields predictions that are largely consistent with the recent findings of cross country club convergence differently from the standard explanation based on multiplicity of steady states this model is also able to yield predictions consistent with observable intra distribution dynamics thus accounting for phenomena such as economic miracles growth disasters and reversals of fortune

confidence and the real value of money in an overlapping generations economy we demonstrate that stochastic bubbles which have a constant exogenous probability of collapsing may exist in general equilibrium on an intrinsically useless and unbacked asset money this may happen provided that the probability q that the bubble will persist next period is large enough and exceeds a threshold level q which we call the minimum rate of confidence this condition is always violated when the economy without bubble is dynamically efficient it is more likely to be satisfied in dynamically inefficient economies the larger the size of the inefficiency as measured by the excess of the growth rate over the no bubble interest rate we study both exchange and production economies

adam smith s analysis of joint stock companies we defend adam smith s theory of the firm from the standpoint of positive economics we argue that his evaluation of the joint stock firm was not moralistic but instead based on available empirical evidence the record showed that joint stock companies had a poor survivorship record even when granted legal monopoly status his analysis contained an explanation of the role of agency costs within the firm finally he did not discuss the east india company as an ordinary joint stock firm but rather as an aberrant form created by government

william j baumol an entrepreneurial economist on the economics of entrepreneurship william j baumol is the 2003 winner of the international award for entrepreneurship and small business research throughout his career baumol has urged the profession to pay attention to the instrumental role of entrepreneurship in economic renewal and growth at the same time he has insisted that economists continue to use their usual tool box when the purview of analysis is extended to entrepreneurship hence baumol can be characterized as a revolutionary from within in this article we present and discuss baumol s research contribution in the areas of entrepreneurship and small business economics notably from a growth perspective in addition to placing his work in these areas into the wider context of his full contribution we emphasize baumol s findings that growth cannot be explained by the accumulation of various factors of production per se human creativity and productive entrepreneurship are needed to combine the inputs in profitable ways as a result an institutional environment that encourages productive entrepreneurship and human experimentation becomes the ultimate determinant of economic growth

fiscal illusion and the grantor government empirical studies indicate that unconditional intergovernmental grants have a flypaper effect several authors have modeled recipient government spending under fiscal illusion to explain this phenomenon in short grants reduce the perceived marginal cost of recipient government output this paper develops a more general model of illusion that incorporates the grantor government thereby eliminating inconsistencies encountered in previous models the more general model implies that grant finance increases the perceived marginal cost of grantor government output thus grant induced illusion should have two effects an increase in recipient output and a decrease in grantor output the empirical work supports this hypothesis

the content of productivity growth in swedish manufacturing abstract it is hardly surprising that the slowdown in economic growth throughout the industrial world in the last decade has attracteda lot of attention by economists the decline in productivity growth has been a special object of study however the causes of this decline still largely remain a mystery in the present paper it is suggested that a more micro based approach to the problem than the conventional macro oriented growth accounting method yields additional insights a methodology is outlined which can at least complement the conventional approach and which is specially designed to open the way for micro analysis of productivity change without losing sight of the macro side this is done by first breaking down total factor productivity growth through disaggregation to lower and lower levels of observation in order to separate out structural from purely technical changes then framework is presented for analyzing how productivity changes at the micro level can be aggregated to the macro level the results emphasize the importance of economies of scale and resource allocation

financial integration entrepreneurial risk and global dynamics abstract how does financial integration impact capital accumulation current account dynamics and cross country inequality we investigate this question within a two country general equilibrium incomplete markets model that focuses on the importance of idiosyncratic entrepreneurial risk a risk that introduces not only a precautionary motive for saving but also a wedge between the interest rate and the marginal product of capital our contribution is to show that this friction provides a simple explanation for the emergence of global imbalances a resolution to the empirical puzzle that capital often fails to flow from the rich or slow growing countries to the poor or fast growing ones and a set of policy lessons regarding the intertemporal costs and benefits of capital account liberalization

a family production overlapping generations economy abstract this paper provides a theoretical analysis of an overlapping generations economy in which production decisions and input output allocations are all carried out at the family level i consider a single class of output allocation schemes and various degrees of knowledge about the production technology under complete knowledge i show that a family organizational structure in which everyone receives his marginal contribution to output invests less in physical capital than under a perfectly competitive equilibrium environment under incomplete knowledge i analyze and compare how beliefs about the input output relationship affect the physical capital accumulation dynamics and the long run standards of living

property tax revaluation and tax levy growth abstract jurisdiction wide property revaluation like many administrative reforms may have unintended consequences this paper examines one such potential consequence by pooling 18 year time series for each of 39 massachusetts cities 17 of which revalued and 270 massachusetts towns 202 of which revalued we examine the hypothesis that politicians take advantage of the confusion generated by revaluation and raise property taxes by more than they otherwise would have we observe such a response in cities but not in towns and attribute this difference to differences in their governmental structures

tax structure and the size of government an empirical analysis of the fiscal illusion and fiscal stress arguments this study attempts to fulfill a number of objectives one is the possible reconciliation of two divergent strains of thought concerning the size of government fiscal illusion and fiscal stress in this respect the results show little evidence of fiscal illusion but provide support for some of the notions associated with the fiscal stress hypothesis namely the effects of revenue and income variability on the size of government

terms of trade and current account dynamics a methodological critique this paper suggests that the recent intertemporal studies concerning the implications of terms of trade deterioration on the current account of a small open economy may suffer from significant methodological deficiencies the study demonstrates that while the assumption of a small open economy represents a legitimate modeling simplification the analysis of the impact of perturbation of the terms of trade on the current account of this small open economy is methodologically erroneous in particular the paper demonstrates that a given pattern of terms of trade deterioration may be associated with opposing evolutionary patterns of the current account of this small economy this paper argues that the methodology employed by several influential intertemporal studies concerning the relationship between the terms of trade and the current account of a small economy suffers from critical deficiencies it demonstrates that while the assumption of a small open economy confronting exogenously determined terms of trade represents a legitimate modeling simplification the analysis of the impact of perturbations of this terms of trade on the small open economy and on its current account is methodologically erroneous in particular the paper demonstrates that a small economy may experience diametrically opposing evolutionary patterns of the current account in association with a given pattern of terms of trade deterioration the paper suggests therefore that predictions based on this literature are in need of reassessment these intertemporal studies of the relationship between the terms of trade and the current account of a small economy have been conducted under the simplifying assumption that perturbations in the terms of trade are exogenous and do not affect the world interest rate 2 this approach may reflect a valid simplification as long as the study is concerned with exportable goods whose prices are insignificant in the determination of the general price level in the world economy however if the focus of the analysis is a small country that exports a group of commodities such as agricultural goods or industrial goods a change in the terms of trade for the small economy may reflect fundamental changes in the world relative prices that are

the causal relation between federal expenditures and receipts federal expenditures have consistently exceeded federal revenues since 1970 in fact the federal government has seen a surplus in only five years since 1950 the symptoms of such fiscal imbalance are of course budget deficits while budget deficits are nothing new in u s history the recent and projected size of the deficit during peacetime nonrecessionary years has been the cause of much concern to academics the news media and politicians this preoccupation with federal deficits has produced a variety of policy proposals to deal with them

the determinants of off budget activity of state and local governments the primary finding of this paper is that the off budget activity of the public sector is significantly and positively related to on budget activity by state and local governments we suggest the following policy implications one there appears to be evidence that the composition of total government activity is related to the relative costs of the alternative avenues of providing governmental activity future research into determining the nature of the relative cost differences may be one useful means of understanding both the composition of government activity as well as its total size two our ability to measure the true size of public sector participation in the economy must go well beyond our attempt here while we have presented information on one of the important hidden elements of public sector participation we are still a long way from effectively incorporating similar data on legislation regulations and so forth into our empirical tests further research into these issues is clearly warranted

an analysis of support for tax limitation referenda explanations for recent upsurges in support for tax reduction measures include 1 a desire to reduce the scope of government activity attiyeh and engle 1979 cbs 1978 1 2 a desire to cut taxes independent of changes in government services levy 1975 levy and zamola 1978 critin 1979 3 a dissatisfaction with the incidence of taxation reid 1979 decanio 1979 none of these explanations predicts when dissatisfaction with taxes will be great enough to cause citizens to act the literature suggests several catalysts that may produce or fail to produce a tax revolt first sales and income taxes produce less revolt since there is relatively little awareness of the amount being paid the incidence of the property tax is much more obvious enrick 1963 wagstaff 1965 gensemer 1965 wagner 1976 ordeshook 1979 a second catalyst is the recency of the assessment reassessment ordeshook 1979 argues that people do not compare their tax burdens with the burdens of others or with the level of government services provided they lack information for such an analysis rather taxpayers react when they experience recent and substantial changes in taxes this paper analyzes certain characteristics of people who sign a petition calling for a referendum to impose a tax limit and of their neighborhoods we hypothesize that

a median voter analysis of variations in the use of property taxes among local governments this paper explores the variations among local governments in the composition of tax revenues or more specifically in the relative use of property taxes using a median voter framework various hypotheses are developed concerning the factors that should influence the relative use of property taxes a cross sectional sample of central cities is employed to test the hypotheses the empirical results are consistent with the hypotheses

infrequent assessments distort property taxes theory and evidence abstract economists have long recognized that lags in property reassessment benefit infrequent movers because it reduces their property taxes but in addition reassessment lags can influence the level of property taxes selected under majority rule i show that short delays in community wide reassessment increase property tax collections because it reduces the tax price for a majority of voters however longer delays reduce property tax collections because the aggregate assessed base and thus the tax yield declines so much i formally characterize the cutoff between these regimes and show tax collections are generally above their socially optimal level this theory can help explain why many people believe property taxes are excessive and it also suggests that the american system of taxing capital gains at realization rather than on accrual might result in excessive rates i test this theory on a sample of pennsylvania municipalities in the philadelphia suburbs this is a suitable crucible for such an evaluation because community wide reassessments are infrequently performed in pennsylvania it is not possible to reject the theory s basic predictions and numerical estimates suggest that a 5 year delay in community wide reassessment increases government revenues by 6 however reassessment delays do not impose statistically significant social losses because they benefit infrequent movers

off budget activities of local government the bane of the tax revolt this paper has demonstrated that the tax revolt of the 1970s has not been as successful in reducing the level of state and local government expenditure as preliminary empirical findings indicate and that the rate of increase in state and local public spending is likely to be far greater than previously believed the evidence presented here shows clearly that constitutional and statutory limitations on the taxing and spending powers of local governments have led to a massive amount of off budget spending and borrowing the debt issued by off budget enterprises is larger and growing at a much faster rate than the voter approved debt issued by state and local governments and has been since 1975 thus even though statistics on property taxation and expenditure may indicate a slow down in the growth of local taxation the true cost of local government may continue to increase at previous rates although this is an empirical question which we are not yet able to address off budget enterprises are heavily subsidized by local state and federal governments these subsidies represent a hidden tax liability to present and future generations of taxpayers in addition the debt and expenditures of obes contribute substantially to the crowding out of private spending and investment

explaining the decision to repeal an optional local tax county governments in pennsylvania have had the option to repeal the intangible property tax since 1978 as of 1992 27 of pennsylvania s 66 counties had repealed it an attempt is made to explain empirically the probability of repeal in this paper the empirical model accounts for a large part of the variation across counties the results show that the probability of levying the intangible property tax is positively related to the projected change in the real estate tax rate further it was found that revenue diversification and several taste and political variables significantly influence the repeal decision these findings are consistent with those of previous tax adoption studies the evidence however does not show the exportation of real estate taxes to have the expected effect on the probability of repeal

a theory of competition among pressure groups for political influence this paper presents a theory of competition among pressure groups for political influence political equilibrium depends on the efficiency of each group in producing pressure the effect of additional pressure on their influence the number of persons in different groups and the deadweight cost of taxes and subsidies an increase in deadweight costs discourages pressure by subsidized groups and encourages pressure by taxpayers this analysis unifies the view that governments correct market failures with the view that they favor the politically powerful both are produced by the competition for political favors

intergenerational altruism and the environment we construct an overlapping generations model of pollution externality in which individuals are altruistically linked to their offspring as in barro 1974 it is shown that steady state consumption may be a decreasing function of the intergenerational degree of altruism despite individuals altruism the competitive equilibrium is not optimal we thus study the social optimum and show that it can be decentralized

tax structure and public sector growth abstract it has been hypothesized that a jurisdiction s tax structure exerts an indipendent effect upon the growth of its public sector we test this hypothesis by examining the relationship between the growth of state general expenditure and the elasticity of tax revenues with respect to income the work takes advantage of a very careful set of income elasticities for the personal income and sales tax systems for each state for every year from 1978 to 1983 the main conclusion is that the data do not support the notion that the form of the tax structure exerts an independent effect on public sector growth

why research partnerships really matter innovation theory institutional arrangements and implications for developing new technology for the poor abstract this paper explores the conceptual basis for existing and emergent institutional patterns in the context of partnership approaches to technology development drawing examples from recent studies of private enterprise activity in india smallholder horticulture it suggests that agricultural innovation as a process involves a wider range of organizational types than the conventional policy focus on public sector research organizations would tend to suggest it uses the concept of a national innovation system to argue that a partnership approach is adopted as a core methodology for engaging science and technology development with the livelihood demands of the poor

social security and demographic shocks an overlapping generations model of social security with shocks to the productivity of labor and capital and demographic shocks is studied we focus attention on stationary long run allocations an allocation is interim optimal if there does not exist another feasible allocation that improves the expected welfare of all generations computed conditionally on the state of the world when they are born we characterize the set of interim optimal allocations and study the equilibria associated with various institutional forms of social security from the point of view of this optimality criterion we obtain the analogs of the two traditional welfare theorems of microeconomic theory assume that there exists a financial asset in fixed quantity which supports some non null intergenerational transfers then the rational expectations equilibrium allocation of this economy is interim optimal conversely any stationary interim optimal allocation can be supported by such an equilibrium with adequate lump sum transfers

long term substitutability between environmental and man made goods abstract substitutability between environmental and man made goods plays a major role in the sustainability debate the notion of substitutability covers a continuous spectrum with perfect substitutability at one end and poor substitutability at the other in this paper it is shown that if economic growth sustains a sharp distinction emerges between perfect and poor substitutability without any intermediate interpretation of substitutability if poor substitutability prevails environmental resources will eventually constitute the major part of total consumption value we relate our results to baumol s disease and assess the implications of this phenomenon for the compensation of environmental losses

global imbalances in the xix xx and the xxi centuries we establish a new stylized fact while the current account and the trade balances are positively correlated during the second globalization 1990s 2010s they were negatively correlated during the first globalization 1870s 1910s we show that the reason behind is that the world interest rate is currently low relatively to the world growth rate due to a global saving glut while this was not the case during the first globalization

love thy children abstract this paper proves that barro s 1974 debt neutrality proposition whose relevance hinges in an economy with bequest motives on bequests being operative in the economy without public debt is not applicable to a wide class of overlapping generation economies those with a weak bequest motive in particular it is shown that the bequest motive is always too weak and public debt therefore non neutral when non physical assets have a well defined function reducing oversavings in the corresponding economy without bequest motive i e when the non altruistic economy is dynamically inefficient

the influence of special district government on public spending and debt growth in special district governments is examined as a reason behind public sector expansion in the united states a theoretical model is developed of the optimal mix of government suppliers which predicts how special district governments affect the overall provision of government policies the hypothesis that expansion of special district governments leads to expansion of the public sector is expirically examined over two time periods

is pension reform conducive to higher saving declining fertility mortality and productivity rates in developed countries and the popularity of the social security privatization in chile as a pathway to financial development have sparked a global interest in social security reform this paper analyzes the effect of social security on saving using a panel of countries over 25 years variation in the characteristics of social security systems is used to determine whether less reliance on a pay as you go unfunded system is associated with higher national saving there is little evidence that countries that implement defined contribution reforms have higher trends in saving rates after the reform cross sectionally countries with pay as you go systems tend to have lower saving rates and this effect increases with the coverage rate on the system

safe debt risky capital the author extends the diamond 1965 model of national debt in two directions she first introduces technological uncertainty and then she allows the stock of debt to vary the author studies the dynamical equilibria of the resulting stochastic system and she establishes conditions for the existence of stationary states that are expressed in terms of invariant distributions since conditions that ensure the existence of a stochastic stationary state with positive debt are very restrictive in this model financial instability is a pervasive phenomenon and allocations are in general dynamically inefficient copyright 1994 by the london school of economics and political science
