inflation and the fiscal limit abstract we use a rational expectations framework to assess the implications of rising debt in an environment with a fiscal limit the fiscal limit is defined as the point where the government no longer has the ability to finance higher debt levels by increasing taxes so either an adjustment to fiscal spending or monetary policy must occur to stabilize debt we give households a joint probability distribution over the various policy adjustments that may occur as well as over the timing of when the fiscal limit is hit one policy option that stabilizes debt is a passive monetary policy which generates a burst of inflation that devalues the existing nominal debt stock the probability of this outcome places upward pressure on inflation expectations and poses a substantial challenge to a central bank pursuing an inflation target the distribution of outcomes for the path of future inflation has a fat right tail revealing that only a small set of outcomes imply dire inflationary scenarios avoiding these scenarios however requires the fiscal authority to renege on some share of future promised transfers

control functions and simultaneous equations methods economic models of agent s optimization problems or of interactions among agents often exhibit simultaneity it is well known that any function in which an explanatory variable is partly determined by the dependent variable of the function cannot be identified without additional information typically this additional information is provided by observable exogenous variables or functional structures here we focus on nonlinear simultaneous equations models with nonadditive disturbances nonlinear nonadditive specifications are a fundamental feature of economic models with unobserved heterogeneity including multidimensional models of consumer and producer choice models of nash equilibrium in industrial organization and many models of labor market behavior in linear models with additive disturbances there are many alternative approaches to addressing endogeneity in estimation twostage least squares instrumental variable and control function approaches are three such commonly adopted approaches in simple specifications of the linear simultaneous model all three approaches generate consistent often analytically identical estimators hausman 1987 for example however linear models with additive

federal lending and the market for credit abstract federal lending is an important but unrecognized feature of modern credit markets this paper analyzes the effects of credit interventions on credit allocation and economic efficiency the underlying model posits asymmetric information between borrowers and lenders and allows for market clearing rationed or redlined equilibria principal results include unsubsidized credit interventions are neutral the relative effectiveness of alternative lending instruments depends on whether rationing occurs interactions among programs can have perverse effects and even without an informational advantage the government may enact welfare improving credit policies under certain conditions

finance and property rights exploring other directions there is a consensus that stronger property rights advance financial development we provide evidence that the reverse hypothesis is also true we isolate the structural component in the finance property rights relationship using an instrument for financial development private credit based on an index of exposure to foreign crises in addition to generalized method of moments approaches for panel data our results suggest a one standard deviation increase in private credit from its average in 2005 translates into a 0 5 to 1 0 point increase in property rights to contextualize this the difference in property rights between israel and uruguay two countries separated by about one standard deviation in the volume of private credit was 0 67 points

financial intermediation and endogenous growth an endogenous growth model with multiple assets is developed agents who face random future liquidity needs accumulate capital and a liquid but unproductive asset the effects of introducing financial intermediation into this environment are considered conditions are provided under which the introduction of intermediaries shifts the composition of savings toward capital causing intermediation to be growth promoting in addition intermediaries generally reduce socially unnecessary capital liquidation again tending to promote growth

occupation induced status social norms and economic growth abstract we analyse a monetary growth model where entrepreneurs borrow funds to invest in projects that produce capital goods in addition to their varying pecuniary returns different projects also vary with respect to the status they confer to the entrepreneurs who operate them we show that i social status increases the growth rate but this effect is mitigated by a social norm that inversely links overall levels of employment in the high return project with the status conferred to it ii the combined effect of social status and inflation is a source of transitional dynamics in an environment where such dynamics would not emerge if considerations of occupational prestige were absent iii when the social norm affects social status the economy s dynamics may be manifested in the form of endogenous volatility iv the presence and characteristics of social status can generate a negative correlation between volatility and growth

endogenous growth and the emergence of equity finance abstract this paper characterises the development of equity markets as a dynamic process that both influences and is influenced by the development of the real sector of the economy in overlapping generations economy borrowers seek funds to run risky investment projects by drawing up contracts which may take the form of either equity or debt issue in the presence of information asymmetry between borrowers and lenders the optimal contract is determined by trading off information dilution costs against bankruptcy costs significantly the equilibrium choice of contract depends on the state of the economy which in turn depends on the contracting regime based on this analysis the paper provides a theory of the joint determination of real and financial development with the ability to explain the emergence of a stock market along the path of real development

tax evasion the underground economy and financial development abstract we study the relationship between the underground economy and financial development in a model of tax evasion and bank intermediation agents with heterogeneous skills seek loans in order to undertake risky investment projects asymmetric information between borrowers and lenders implies a menu of loan contracts that induce self selection in a separating equilibrium faced with these contracts agents choose how much of their income to declare by trading off their incentives to offer collateral against their disincentives to comply with tax obligations the key implication of the analysis is that the marginal net benefit of income disclosure increases with the level of financial development thus in accordance with empirical observation we establish the result that the lower is the stage of such development the higher is the incidence of tax evasion and the greater is the size of the underground economy

public capital asymmetric information and economic growth we investigate the provision of public capital in an endogenous growth model with asymmetric information in a credit market with costly screening we show that the equilibrium contracts are characterized by the self selection of borrowers through identifying an additional adverse effect of taxation on growth we show that the optimal tax rate in our model is smaller than the output elasticity of public capital therefore our analysis justifies a more conservative tax policy in the presence of asymmetric information furthermore our model suggests a number of implications that appear to be well supported by preliminary evidence in cross country data jel classification d82 h21 041

a game theoretic view of the fiscal theory of the price level the goal of this paper is to probe the validity of the fiscal theory of the price level by modelling explicitly the market structure in which households and the government make their decisions i describe the economy as a game and i am thus able to state precisely the consequences of actions that are out of the equilibrium path i show that there exist government strategies that lead to a version of the fiscal theory in which the price level is determined by fiscal variables alone these strategies are however more complex than the simple budgetary rules usually associated with the fiscal theory and the government budget constraint cannot be merely viewed as an equilibrium condition

aging and deflation from a fiscal perspective negative correlations between inflation and demographic aging were observed across developed nations recently to understand the phenomenon from a politico economic perspective we embed the fiscal theory of the price level into an overlapping generations model in the model successive short lived governments choose income tax rates and bond issues considering the political influence of existing generations and the policy response of future governments the model sheds new light on the traditional debate about the burden of national debt because of price adjustments the accumulation of government debt does not become a burden on future generations our analysis reveals that the effects of aging depend on its causes aging is deflationary when caused by an increase in longevity but inflationary when caused by a decline in birth rate numerical simulation shows that aging over the past 40 years in japan generated deflation of about 0 6 percentage points annually

capital requirements screening and interlinked sharecropping and credit contracts this paper provides one more rationale for interlinking credit and tenancy contracts in the context of production loans in an environment characterized by a heterogeneous labor pool and imperfect information landlords will have an incentive to avail themselves of screening devices by linking tenancy and credit contracts a screening device can be implemented the equilibrium set of contracts is characterized by a variety of interest rates some of which might be below the market interest rate the interest rate principal schedule is downward sloping with higher ability tenants choosing larger principals at lower interest rates

fair implementation of diversity in school choice many school districts have objectives regarding how students of different races ethnicity or religious backgrounds should be distributed across schools a growing literature in mechanism design is introducing school choice mechanisms that attempt to satisfy those requirements we show that mechanisms based on the student proposing deferred acceptance may fail to satisfy those objectives but that by using instead the school proposing deferred acceptance together with a choice function used by the schools which incorporates a preference for satisfying them can optimally approximate the diversity objectives while still satisfying an appropriate fairness criterion we provide analytical results which show that the proposed mechanism has a general ability to satisfy those objectives as opposed to some currently proposed mechanisms which may yield segregated assignments

a survey of recent developments in the literature of finance and growth this paper provides a survey of the recent progress in the literature of financial development and economic growth the survey highlights that most empirical studies focus on either testing the role of financial development in stimulating economic growth or examining the direction of causality between these two variables although the positive role of finance on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies several key issues unresolved in the literature are highlighted the paper also points to several directions for future research

money as stock abstract the fiscal theory determines the price level from the value of nominal government debt as a claim to government primary surpluses just as private stock is valued as a claim to corporate profits valuation equations are not constraints so this theory does not mistreat the government s intertemporal budget constraint i anchor the analysis in a simple cash in advance model when money demand falls to zero i show that the price level can still be determined by the government debt valuation equation

good bye financial repression hello financial crash some unintended consequences of financial liberalization in latin america are analyzed in this paper intrinsic imperfectious in financial markets and the policy dilemmas they pose are reviewed first the stylized facts of southern cone experiments in financial liberization are then presented alternative ways of organlzing domestic capital markets under latin american conditions are discussed and an eclectic reform mongering program is proposed

factor income taxation and growth under asymmetric information abstract this paper studies the growth effects of factor income taxation on capital and labor in an endogenous growth model with overlapping generations capital accumulation in our model takes place through credit financed investments in a market with asymmetric information between lenders and borrowers we show that in the presence of asymmetric information capital income taxation worsens the adverse selection problem in the credit market which in turn introduces an additional adverse effect on growth in so doing our analysis provides a new argument in favor of a lower higher capital labor income taxation in funding public expenditures

why a stubborn conservative would run a deficit policy with time inconsistent preferences a conservative government in favor of a low level of public consumption knows that it will be replaced by a government in favor of a larger level of public consumption we show that the resulting level of public consumption is in between the levels the two governments would choose if each were in power both in the present and in the future in particular we show that if the conservative government is more stubborn in a particular sense than the succeeding government the conservative government will borrow more than it would had it remained in power in the future

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

production growth and business cycles ii new directions abstract this paper outlines new directions for investigations of real business cycle models consideration of stochastic growth of exogenous and endogenous forms analysis of suboptimal outcomes arising due to externalities of distorting taxes and implications of labor market heterogeneity

on financial innovations and credit market evolution abstract this paper examines the role of financial innovations in the economic development process it discusses the place of policy intervention in the financial development of developing countries and through a case study of an innovative bank illustrates the nature and characteristics of the financial innovations necessary for financing small enterprises and mobilizing resources from low and middle income groups such financial innovations are shown to reduce transaction costs and risk and as a result to bring about widening deeping and intergration of capital markets this process accelerates economic development through a favorable impact on savings investment and output

labor supply elasticity and social security reform abstract previous literature on social security reform has used a variety of period utility functions and calibrated values for the intertemporal elasticity of substitution ies in labor in this paper we show that the effects of social security reforms on aggregate labor supply are invariant to plausible values of the ies but the effect of such reforms on the profile of hours over the life cycle is highly sensitive to the ies we first establish these results analytically in a simple partial equilibrium setting and then demonstrate their robustness in a general equilibrium model calibrated to match key u s macroeconomic indicators we find that the aggregate effects are similar regardless of the wide range of the values of ies used in calibrated economies however social security reform leads to a large reallocation of hours worked over the life cycle from early years to later working years and the size of this reallocation significantly increases with the ies

the laffer curve revisited abstract laffer curves for the us the eu 14 and individual european countries are compared using a neoclassical growth model featuring constant frisch elasticity cfe preferences new tax rate data is provided the us can maximally increase tax revenues by 30 with labor taxes and 6 with capital taxes we obtain 8 and 1 for the eu 14 there 54 of a labor tax cut and 79 of a capital tax cut are self financing the consumption tax laffer curve does not peak endogenous growth and human capital accumulation affect the results quantitatively household heterogeneity may not be important while transition matters greatly

tax evasion and financial development under asymmetric information in credit markets abstract recent empirical studies have documented that after controlling for variables related to state capacity the incidence of firms tax evasion on their sales is negatively correlated with the level of a country s financial development motivated by this stylized fact our paper takes state capacity as given and provides an alternative theory that is built upon asymmetric information in credit markets particularly within developing economies we analytically show that with a more developed financial sector that exhibits smaller agency costs the government of a rich small open economy country will raise its optimal tax auditing probability which in turn leads to more tax compliance our baseline model also yields an empirically realistic positive correlation between financial development and the ratio of tax revenue over gdp in an extended setting which allows for size dependent probabilities of tax detection we find that consistent with the empirical evidence large firms comply with taxes whereas small firms evade taxes

national and international aspects of financial policies in ldcs a prologue after a period of animated controversy between keynesians advocating policies of low interest rates and monetary expansion and monetarists who insisted on the importance of the distinction between nominal and real interest rates economists have now almost reached a consensus on the role of money in the development process this consensus has arisen because it was increasingly felt that what was called for was not new concepts so much as new ways of looking at them in ldcs money s role need be neither denigrated nor exaggerated money s traditional functions as a medium of exchange and a store of value remain important in ldcs but its function as a conduit of resources from savers to investors is more central to an inderstanding of its contributions to development coats and khatkhate 1980 p 3 the body of the consensus derives from the framework set up by mckinnon and shaw fleshed out by the earlier work of goldsmith and patrick goldsmith 1969 patrick 1966 and extended by the theoretical and empirical output of a large number of younger economists fry 1981 this analysis attached central importance to financial policies of higher real interest rates which were supposed to encourage the build up of real money balances increased financial intermediation and unification of financial markets eventually such a policy would lead to the efficient utilization of resources and particularly of scarce capital this new paradigm has contributed to an improved understanding and perception of the economies of ldcs their problems and how these problems are accentuated by distortions arising from interventionist policies for a while it was believed that the programme contained the secret of how to reconcile stabilization objectives with those of development roe 1982 however the accumulation of empirical evidence on several developing countries where the prescribed set of policies was adopted has raised doubts about the validity of this conclusion in the presence of distortions in the financial markets it is no doubt a sensible policy to raise real interest rates the problematic issue is how far to go raising real interest rates without any regard for the rates of return on investment may run counter to the requirements of development to argue that once funds are generated through the accumulation of real balances investment can take care of itself ignores the very dynamics of development thus the hiatus between stabilization and development has not really been bridged this is evident from the recent concern with supply side policies rather than demand management policies a dichotomy which parallels the distinction between the stabilization and development problems it is this dual distinction which provides the theme of this special issue of world development

the optimal public expenditure financing policy does the level of economic development matter i introduction does the growth effect of public expenditures depend on the way these expenditures are financed over the years a substantial volume of theoretical and empirical research has been directed toward identifying the elements of public expenditure at its aggregated and disaggregated level that bear significant association with economic growth in contrast only a handful of studies have paid particular attention to examine the extent to which the growth effect of public expenditures depends on the method of financing such expenditures e g de gregorio 1993 miller and russek 1997 palivos and yip 1995 the consensus appears to be that the two primary modes of financing income taxation and seigniorage are distortionary opinions however are divided as to their relative merits for example according to palivos and yip 1995 income tax financing is more detrimental to growth than seigniorage financing at the same time de gregorio 1993 suggests that as long as the rate of return on indexed bonds is substantially responsive to changes in the rate of inflation seigniorage financing of public expenditure is more growth reducing pecorino 1997 on the other hand prescribes a mix of both modes of financing despite these differences the above mentioned studies share a common characteristic the optimal mode of financing public expenditure in these studies is viewed as being not contingent on the stages of economic development accordingly there remains little understanding of the process by which public expenditure financing policies shape the prospect of economic growth for developing vis a vis developed countries the primary objective of this paper is to bridge this gap in the existing literature it is a long standing belief among development experts that outcomes of public expenditures and revenue policies are conditional on the state of an economy recent evidence supports such belief for example miller and russek 1997 suggest that for developing countries a deficit financed increase in public expenditure retards economic growth and a tax financed increase leads to higher growth for developed countries a deficit financed increase in government expenditure does not affect economic growth and a tax financed increase leads to a lower growth in light of these findings and in light of the theoretical controversy about the relative merits of seigniorage versus tax finance it is meaningful to ask the following question does the relative merit of seigniorage vis a vis tax financing of public expenditure depend on the stage of economic development this paper seeks an answer to this question using both theoretical and empirical analyses the theoretical framework developed in this paper shares many of the characteristics of the models proposed by espinosa vega and yip 1999 2000 and schreft and smith 1997 in particular we consider a two period overlapping generations model where agents are subjected to stochastic relocations shocks which act like shocks to their portfolio preferences these shocks have the same consequence as liquidity preference shocks as in diamond and dybvig 1983 and create a role for financial intermediaries who take deposits and make a portfolio decision on behalf of the households in addition there is a government that relies on two alternative sources of revenue seigniorage and tax revenue to finance its exogenously given expenditure sequence the results that we derive are shaped by the portfolio decision of the financial intermediaries in particular at each point in time financial intermediaries are required to allocate their portfolios between a nonproductive liquid asset money and a productive illiquid asset the illiquid asset takes the form of financing risky investment projects which in turn generate productive capital stock for the economy the financial intermediaries optimal portfolio allocation rules depend on the relative rate of return of the two available assets

some consequences of credit rationing in an endogenous growth model an endogenous growth model is developed where all investment is financed via credit extension there is also an adverse selection problem in loan markets so that in equilibrium credit rationing arises endogenously the result is that equilibrium levels of credit rationing and real growth rates are jointly determined in this context several changes in the environment can have unusual consequences for instance improvements in the technology for producing capital can reduce growth because of their adverse impacts on credit rationing for similar reasons various government investment subsidies can be growth reducing this phenomenon is often observed empirically

the growth effects of property rights the role of finance summary using a variety of statistical approaches we show that the relationship between property rights and growth is nonlinear stronger enforcement of property rights raises growth up to a point before growth begins to decline we provide a simple theoretical rationale for this conclusion using a model with informational asymmetries in the financial sector stronger property rights have two opposing effects on the one hand it increases capital formation and growth on the other hand it encourages bad borrowing practices thus there exists an optimal level of property rights which maximizes growth however as financial markets mature the negative effects associated with stronger property rights become weaker

a dynamic new keynesian life cycle model societal aging demographics and monetary policy in this paper we first construct a dynamic new keynesian model that incorporates life cycle behavior a la gertler 1999 in order to study whether structural shocks to the economy have asymmetric effects on heterogeneous agents namely workers and retirees we also examine whether considerations of life cycle and demographic structure alter the dynamic properties of the monetary business cycle model specifically the degree of amplification in impulse responses according to our simulation results shocks indeed have asymmetric impacts on different households and the demographic structure does alter the size of responses against shocks by changing the degree of the trade off between substitution and income effects

voting on the budget deficit this paper analyzes a model in which a group of rational individuals votes over the composition and time profile of public spending all voters agree that a balanced budget is ex ante optimal however if there is disagreement between current and future majorities a balanced budget is not a political equilibrium under majority rule under certain conditions a majority of the voters favors a budget deficit and the equilibrium deficit is larger the greater is the polarization among voters copyright 1990 by american economic association

investment climate and firm productivity an application to vietnamese manufacturing firms abstractthe fundamental aspect of a national competitive advantage is a good investment climate understanding the role of the investment climate in generating firm productivity has received extensive attention by policymakers and economists in many countries the article studies the effect of different dimensions of the investment climate on firm productivity using a large dataset of vietnamese manufacturing firms the article finds that deficiencies in the investment climate are prejudicial to firm productivity and competition furthermore in examining the effect of corruption in association with the quality of the business environment the study also investigates the possibility that corruption may compensate firms for a bad investment climate or at least may neutralize the negative impact of inefficient government regulations in other words corruption acts as speed money to improve the efficacy of the provision of public services or provides leeway for entrepreneurs to bypass the inefficient reg

credit rationing and capital accumulation with investment and consumption loans revisited abstract a simple model is developed to evaluate the roles of credit rationing and government policies of financial repression in the process of capital accumulation in the model credit rationing on both investment and consumption loans decreases as capital accumulates but increases as the government imposes policies of financial repression to a greater extent while a reduction in credit rationing on consumption loans impedes capital accumulation such a reduction on investment loans facilitates it we find that developing countries may be trapped at a low capital stock steady state while developed countries converge to a high capital stock steady state instead of adopting policies of financial liberalization interestingly this paper finds that policies of financial repression may enable developing countries to escape the development trap

anatomy of financial retardation in a less developed country the case of sri lanka 1951 1976 abstract an attempt is made in this paper to analyse the experience of sri lanka during 1951 1976 particularly in relation to its financial sector development it is shown that the interventionist regime held the key to the pace and pattern of the economy s development whether it was the skimpy growth of the financial system the faltering progression of gnp the precarious foreign exchange position or the persistence of inflationary pressure they were all traceable to the impact on the financial system of a particular set of policies pursued the year 1977 however marked a watershed in sri lanka s long quest for economic development the government began to unwind the entire paraphernalia of administered controls on consumption investment and foreign exchange most of the price controls were removed subsidies phased out and public corporations were allowed greater autonomy in their pricing and distribution policies it is necessary to contrast this situation with what existed prior to 1977 in order to assess its impact on the real economy of sri lanka only then can the cost of financial retardation be measured

equilibrium credit rationing of small farm agriculture it is often argued that externally imposed contractual restrictions lead to inequitable credit rationing this paper argues that unrestricted laissez faire markets may also inequitably ration credit a formal model which grants borrowers autonomy in credit application and use demonstrates that adverse incentive and selection effects may cause banks to endogenously impose interest rate restrictions and ration small farms out of the credit market consequently liberalization of financial markets may be insufficient to guarantee small farms access to credit

economies of scale for various types of manufacturing production technologies in an underdeveloped economy manufacturing sector 2 all these studies suffer from at least three weaknesses first almost all of them have used either the cobbdouglas or the constant elasticity of substitution ces production functions which are highly restrictive second many have used time series analysis without proper attention to time lags and the problems of multicollinearity also they have neglected to separate fully the effects of technological changes on cost from those of the economies of scale third they have invariably assumed labor and capital to be the main factors of production raw materials inputs which are a considerable element of the total cost of production and could therefore cause significant changes in the estimated elasticities of substitution and consequently in the estimates of returns to scale have been ignored altogether 3 the purpose of this paper is to overcome all these weaknesses by using a flexible functional form and simultaneously to estimate returns to scale and elasticities of substitution specifically we use the transcendental logarithmic cost function introduced by christensen jorgenson and lau4 to estimate the measured characteristics of technology for india s manufacturing industries for purposes of comparison we also focus on various specifications of the production technology we describe all functions in terms of a translog specification and distinguish other technologies with appropriate parametric restrictions

the indeterminacy of prices under interest rate pegging the non ricardian case abstract this paper investigates the issue of price level indeterminacy under a pure interest rate peg in models that depart from standard ricardian assumptions using a monetary version of blanchard s finite horizons model i find wealth effects operating on government bonds are not sufficient to determine a unique price level next i consider price determination under a non ricardian fiscal authority i show that if agents rationally perceive the possibility of fiscal default the price level is again indeterminate i conclude that departures from ricardian equivalence are not sufficient to ensure a unique price level under a monetary policy of pure interest rate pegging

credit policy inflation and growth in a financially repressed economy this report analyzes credit policy in an open economy macro model incorporating stylized facts about the financial sector of ldc s absence of security markets existence of a curbmarket these facts are incorporated in the financial sector part of a keynes wicksell growth model it focuses on a transmission channel of monetary policy into the supply side of the economy via the cost of working capital it shows that ignoring this effect when analysing restrictive credit policy leads to underestimates of inflation and overestimation of output and current account improvements it is shown that a credit crunch can be stagflationary in the short run a cut in the real stock of credit is shown to lead to a lower steady state capital stock

law and finance at the origin what are the key determinants of financial development and growth a large literature debates the relative importance of countries legal and political environment in this paper i present evidence from ancient rome where an early form of shareholder company the societas publicanorum developed i show that the societas publicano rum flourished in a legally underdeveloped but politically supportive environment roman republic and disappeared when roman law reached its height of legal sophistication but the political environment grew less supportive roman empire in the roman case legal development appears to have mattered little as long as the law as practiced was flexible and adapted to economic needs the law as practiced in turn reflected prevalent political interests after discussing parallels in more recent history i provide a brief overview of the literature on law and finance and on politics and finance the historical evidence suggests that legal systems may be less of a technological constraint for growth than previously thought at least at the origin
