the dynamic effects of government spending policies in a two sector endogenous growth model this paper investigates the impact of government spending policies in a two sector model of endogenous growth endogenous growth arises because all factors of production physical and human capital are reproducible both temporary and permanent government spending shocks are examined the model implies that a permanent lump sum financed increase in government spending raises the long run growth rate this occurs because the negative wealth effects of a spending increase will increase labor supply on the other hand an income tax or wage tax financed rise in government spending reduces the growth rate the output effects of a temporary increase in government spending may be greater or less than a permanent increase in spending copyright 1995 by ohio state university press

state contingent bank regulation with unobserved actions and unobserved characteristics abstract optimal bank regulation is studied in a model where bank quality is private information and bank portfolio choice is subject to moral hazard regulators wish to control bank risk solely because high risk adversely affects a bank incentives to improve its mean return numerical methods are developed to study the model capital regulation alone has a limited ability to separate types including ex post fines achieve separation at lower cost resulting in improved welfare low quality banks are fined on high returns in order to control risk taking high quality banks face fines on lower returns mainly to ensure truth telling by low quality banks high quality banks bear the full cost of regulation

fiscal policy and growth in a small open economy with elastic labour supply endogenizing labour supply leads to fundamental changes in the equilibrium structure of the ak growth model of a small open economy the balanced growth equilibrium is described by two tradeoff loci relating the equilibrium growth rate to the fraction of time devoted to leisure the implications of endogenous labour supply for fiscal policy are addressed the effects of distortionary taxes and government expenditure on the equilibrium growth leisure employment tradeoff are analysed the responses contrast with both those of a closed economy having an elastic labour supply and an open economy with fixed labour supply optimal fiscal policy is also characterized jel classification f41 f43 politique fiscale et croissance dans une petite economie ouverte quand l offre de travail est elastique l endogeneisation de l offre de travail entraine des changements fondamentaux dans la structure d equilibre du modele de croissance du type ak d une petite economie ouverte l equilibre de croissance balancee est decrit par deux lieux de relations d equivalence reliant le taux de croissance d equilibre a la fraction du temps allouee au loisir on examine les implications de cette endogen6isation de l offre de travail pour la politique fiscale on analyse les effets de taxes distorsionnantes et des depenses gouvemementales sur la relation d 6equivalence entre taux de croissance et loisir et donc emploi on obtient des reactions differentes de celles qu on obtient en economie ferm6e quand l offre de travail est elastique et en economie ouverte quand l offre de travail est fixe on proc ede alors a la definition de la politique fiscale optimale

increasing returns capital utilization and the effects of government spending abstract we show that a one sector real business cycle model with mild increasing returns to scale variable capital utilization and saddle path stability is able to produce qualitatively realistic business cycles driven solely by disturbances to government purchases due to an endogenous increase in labor productivity a positive spending shock can lead to simultaneous increases in output consumption investment employment and real wage our analysis illustrates a close relationship between this result and the recent literature that explores indeterminacy and sunspots in real business cycle models under laissez faire in particular the condition which governs the required magnitude of increasing returns for government spending shocks to generate procyclical macroeconomic effects is identical to that necessary for a laissez faire one sector real business cycle model to exhibit local indeterminacy

comovement in international equity markets a sectoral view abstract we investigate shifts in correlation patterns among international equity returns at the market level as well as the industry level we develop a novel bivariate garch model for equity returns with a smoothly time varying correlation and then derive a lagrange multiplier statistic to test the constant correlation hypothesis directly applying the test to weekly data from germany japan the uk and the us in the period 1980 2000 we find that correlations among the german uk and us stock markets have doubled whereas japanese correlations have remained the same both dates of change and speeds of adjustment vary widely across countries and sectors

index investment and financialization of commodities the authors found that concurrent with the rapidly growing index investment in commodity markets since the early 2000s prices of non energy commodity futures in the united states have become incr

evolution of international stock and bond market integration influence of the european monetary union abstract this paper examines the dynamic relationship between daily stock and government bond returns of selected countries over the past decade to infer the state and progress of inter financial market integration we proceed to empirically investigate the influence of the european monetary union emu on time variations in inter stock bond market integration segmentation dynamics using a two step procedure first we document the downward trends in time varying conditional correlations between stock and bond market returns in european countries japan and the us second we investigate the causality and determinants of this interdependent relationship in particular whether the various macroeconomic convergence criteria associated with the emu have played a significant role we find that real economic integration and the reduction in currency risk have generally had the desired effect on financial integration but monetary policy integration may have created uncertain investor sentiments on the economic future of the emu thereby stimulating a flight to quality phenomenon

asymmetric increasing trends in dependence in international equity markets abstract this paper investigates asymmetric increasing trends in dependence in major international equity markets to this end we develop a multiple regime smooth transition copula garch model and address several important questions including the number of regimes and the existence of increasing asymmetric trends in dependence our results suggest that two or three regimes are sufficient for describing the dependence trends in international equity markets over the last 35 years with significant asymmetric increases in addition the implied time series of three dependence measures show a wide variety of dynamics demonstrating the usefulness of our framework to describe asymmetric increasing dependence trends finally we evaluate the economic significance of our empirical finding based on the 99 value at risk and expected shortfall our result indicates that both risk measures have increased approximately 20 over the last 35 years in major equity markets

insuring banks against liquidity shocks the role of deposit insurance and lending of last resort it has long been recognized that banks simultaneous provision of monitoring and liquidity services is advantageous but leaves them susceptible to liquidity shocks that may culminate in a system failure because a system failure is costly this provides a rationale for adopting arrangements including a lender of last resort and deposit insurance di to insure banks against liquidity shocks these arrangements have proven themselves very successful but they have also been the source of problems researchers have identified some of the main sources of these problems and have suggested ways to improve the design of these arrangements but there are still many issues that remain unaddressed this paper reviews the literature on the two arrangements that most countries have adopted to insure banks against liquidity shocks a lender of last resort and di and compares the design of these arrangements across countries the paper ends with a brief summary of the key lessons learned about the design of these arrangements and the issues related to them that remain unaddressed copyright blackwell publishers ltd 2006

the impact of military burden on long run growth and welfare abstract this paper presents an endogenous growth model to examine how a government s resource allocation between the defense and non defense sectors will govern both economic growth and social welfare we demonstrate that there exists an optimal defense expenditure share that maximizes the economic growth rate but this rate is smaller than the welfare maximizing share this result can be viewed as a possible vehicle to explain why in many developing countries arms limitation and disarmament negotiations usually have low performance even failing

competitive equilibrium and public investment plans abstract we examine a one sector growth model in which public capital is an external input to private production functions revenues from taxing capital and labor income are used to fund public investments the competitive equilibrium can be obtained by solving an artificial planning problem we prove that there exists a unique competitive equilibrium which can be characterized by euler equations and a transversality condition we then establish the existence of an optimal public investment plan

schooling and public capital in a model of endogenous growth this paper studies the allocation of public spending between education services and infrastructure investment in an endogenous growth model where public capital in infrastructure affects the process of human capital accumulation the balanced growth path is derived and the dynamics associated with a budget neutral reallocation of spending from education to infrastructure are studied through numerical simulations the growth maximizing tax rate is shown to depend only on the production technology as in standard flow models of public expenditure whereas the optimal share of infrastructure investment depends also on the productiveness of infrastructure relative to education services in the schooling technology

endogenous markups and the effects of income taxation theory and evidence from oecd countries abstract existing studies on the effects of fiscal policy under imperfect competition typically treat each firm s price cost markup as fixed this paper examines the implications of endogenising the markup in a simple model of income taxation under monopolistic competition it is demonstrated that an increase in income tax reduces the number of firms lessens competition among surviving firms and raises the optimal markups in the new steady state through this channel the effects of income taxation on the key macroeconomic variables as well as on consumer welfare are unambiguously enlarged the simple model prediction is largely supported by cross section regressions with data from oecd countries

index investment and the financialization of commodities the authors found that concurrent with the rapidly growing index investment in commodity markets since the early 2000s prices of non energy commodity futures in the united states have become increasingly correlated with oil prices this trend has been significantly more pronounced for commodities in two popular commodity indices this finding reflects the financialization of the commodity markets and helps explain the large increase in the price volatility of non energy commodities around 2008

banking deregulation allocational consequences of relaxing entry barriers abstract we present an equilibrium analysis to predict the long run allocational consequences and risk implications of banking deregulation loan demand and deposit supply functions are derived from primitive assumptions about the preferences of individuals and banks are viewed as differentiated competitors in a spatial context we find that a relaxation of entry barriers into banking improves the welfare of borrowers and savers at the expense of bank stockholders equilibrium loan interest rates fall and equilibrium deposit interest rates rise as banking becomes more competitive despite this the equilibrium debt equity ratios of banks increase as entry barriers are relaxed we also examine the implications of capital standards and find that an increase in the minimum capital requirement benefits borrowers but hurts depositors

is the relationship between financial development and economic growth monotonic evidence from a sample of middle income countries summary we revisit the relationship between financial development and economic growth in a panel of 52 middle income countries over the 1980 2008 period using pooled mean group estimations in a dynamic heterogeneous panel setting we show that there is an inverted u shaped relationship between finance and growth in the long run in the short run the relationship is insignificant this suggests that too much finance can exert a negative influence on growth in middle income countries the finding of a non monotonic effect of financial development on growth is confirmed by estimating a threshold model

an alternative to steady state comparisons in perfect foresight models abstract this note examines a technique for the computation of the welfare impact of a pertubation of the steady state in a typical perfect foresight model the major innovation is the ability to analyze non stationary perturbations

sustainability of public debt public capital formation and endogenous growth in an overlapping generations setting abstract under the golden rule of public finance for public investment with a constant budget deficit gdp ratio we show that for the sustainability of government budget deficits there is a threshold of the initial public debt for a given stock of public capital and that this threshold level of public debt is increasing in the stock of public capital if the initial public debt is greater than the threshold the government can no longer sustain budget deficits while if it is smaller the government can conduct a permanent deficit policy which eventually leads to a positive public debt gdp ratio

public budgetary rules and gdp growth an empirical study on oecd and twelve european countries we study the long term effects of budgetary rules on gdp growth rate and analyse the determinants of the short term gdp growth dynamics for both a sample of 19 oecd and a subsample of 12 european countries we show that in the long run improvements in the cyclically adjusted budget balance as well as increases in the tax burden have negative effects on gdp growth the highest effect of fiscal policy on gdp growth would be obtained if the structural deficits were used to increase the market size by reducing the tax burden in line with barro 1990 a deficit financed reduction of tax burden has a stronger effect for european than for oecd countries because in europe the government size with respect to market size is too large therefore if gdp growth is a dominant policy objective in europe specific actions should redress the 2012 treaty toward a reduction of the tax burden

an incentive approach to banking regulation we examine the optimal design of a risk adjusted deposit insurance scheme when the regulator has less information than the bank about the inherent risk of the bank s assets adverse selection and when the regulator is unable to monitor the extent to which bank resources are being directed away from normal operations toward activities that lower asset quality moral hazard under a socially optimal insurance scheme 1 asset quality is below the first best level 2 higher quality banks have larger asset bases and face lower capital adequacy requirements than lower quality banks and 3 the probability of failure is equated across banks perihaps t he most troubling aspect of the current deposit insurance system is the distortions caused by the pervasive use of an insurance premium that is independent of risk the undesirable incentives that result when such a system is employed in a world with imperfect information have long been recognized in the literature of particular concern is the incentive banks have to increase the risk of their portfolio in order to maximize the value of the deposit insurance provided in some respects this problem is similar to the incentives generated by corporate debt however the solution to this problem may be different in a banking context because the creditors include the deposit insurer who has the power to regulate the banks conceivably regulation may be able to mitigate the informational problem at hand in this paper we examine some of the tradeoffs that arise in the design of a regulatory system for banks

the welfare cost of bank capital requirements abstract capital requirements are the cornerstone of modern bank regulation yet little is known about their welfare cost this paper measures this cost and finds that it is surprisingly large i present a simple framework which embeds the role of liquidity creating banks in an otherwise standard general equilibrium growth model a capital requirement limits the moral hazard on the part of banks that arises due to deposit insurance however this capital requirement is also costly because it reduces the ability of banks to create liquidity the key insight is that equilibrium asset returns reveal the strength of households preferences for liquidity and this allows for the derivation of a simple formula for the welfare cost of capital requirements that is a function of observable variables only using us data the welfare cost of current capital adequacy regulation is found to be equivalent to a permanent loss in consumption of between 0 1 and 1

does precommitment raise growth the dynamics of growth and fiscal policy we develop an endogenous growth model driven by externalities from both private and public capital the government levies distortionary taxation to finance a publicly provided consumption good and public infrastructure firms face adjustment costs we compare the optimal and time consistent policies in a linear quadratic approximation of the model although the timeconsistent equilibrium is sub optimal in terms of ex ante intertemporal welfare it yields higher long run growth and welfare through an accumulation of assets by the state and a cut in government consumption

forbearance deposit insurance pricing and incentive compatible bank regulation abstract this paper examines the incentive compatible role of regulatory forbearance policy in the context of optimal bank regulation under moral hazard we show that when a bank s asset portfolio returns have market risk the regulator can influence the bank s choice of ex ante risk by delaying the closure of an insolvent bank the optimal closure policy involves co ordinating the closure decision with market wide performance such a policy may significantly alleviate the bank s ex ante risk shifting problem furthermore even fixed rate deposit insurance can be optimal when combined with a sound forbearance policy and a minimum capital standard

scale congestion and growth this paper explores the relationship between aggregate and relative congestion returns to scale and economic growth aggregate congestion reduces the effective productivity of capital relative congestion reduces the effective productivity of labour both forms of congestion adversely affect the equilibrium growth rate although their relative effects depend upon aggre gate returns to scale the two forms of congestion have contrasting effects on the transitional dynamics relative congestion retards the rate of adjustment aggregate congestion accelerates it the externalities generated by congestion and non optimal expenditure can be fully cor rected both during the transition and in steady state by a time invariant income tax the role of public expenditure as an instrument of economic growth has been a major policy issue as governments throughout the world design stimulus packages as in japan and face difficult choices to meet the emu criteria in europe empirical research investigating the impact of public investment on the productivity of private capital and output was stimulated by aschauer 1989a b who found the effects to be strongly positive the nature of public investment is however diverse in general public goods vary extensively in terms of the nature of their services spanning the range between the polar cases of pure private and pure public goods but the treatment of public expenditures in formal growth models is limited barro 1990 and futagami et al 1993 treat government expenditure as a pure pub lic good and in so doing they fail to take account of the congestion typically associated with public goods however as barro and sala i martin 1992 have argued almost all public services are characterized by some degree of congestion so that the pure public good should be viewed as only a bench mark these considerations suggest that congestion is an important consider ation in assessing the effect of public expenditures on economic growth attempts to analyse the effects of congestion on economic growth have been limited in various dimensions drawing on the public goods literature edwards 1990 proposes a number of specifications of congestion two notions particularly relevant in a growth context are relative congestion and aggregate absolute congestion the former specifies the level of services derived by an individual from the provision of a public good in terms of the usage of his individual capital stock relative to the aggregate capital stock aggregate congestion sometimes called crowding indicates how aggregate usage of the service alone influences the services received by an individual 2 existing applications of congestion to growth theory introduce it into ak models see barro and sala i martin 1992 1995 glomm and ravikumar 1994 1997 and turnovsky 1996 1997 however the ak model features two limitations that restrict its flexibility to examine the relationship between congestion and growth first as solow 1994 pointed out sustained ongoing

state contingent regulatory mechanisms and fairly priced deposit insurance abstract this paper presents a model of incentive compatible bank regulation under moral hazard and adverse selection we derive a wide range of simple and conceptually implementable mechanisms that can solve each type of incentive problem separately and also achieve the first best outcome but only when regulatory instruments involve ex post pricing that is contingent on the bank s performance relative to the market an important feature of these mechanisms is that they do not involve a subsidy to the bank when the regulator faces both moral hazard and adverse selection simultaneously we identify the conditions under which the same mechanism can achieve the first best solution

income taxes public investment and welfare in a growing economy abstract in a growth model with public capital and a spillover externality from private capital we find that income taxes as part of an optimal fiscal policy is a more common result than usually thought the commitment to finance an exogenous component of public expenditures in the form of an exogenous fraction of output may lead to the optimality of positive income taxes this result is robust to alternative assumptions on depreciation rates and preferences we show that welfare losses from deviations from the optimal policy are always smaller when compensated with changes in income taxes than when adjusting lump sum taxes

is infrastructure capital productive a dynamic heterogeneous approach this paper offers an empirical evaluation of the output contribution of infrastructure drawing from a large data set on infrastructure stocks covering 88 countries and spanning the years 1960 2000 and using a panel time series approach the paper estimates a long run aggregate production function relating gdp to human capital physical capital and a synthetic measure of infrastructure given by the first principal component of infrastructure endowments in transport power and telecommunications tests of the cointegration rank allowing it to vary across countries reveal a common rank with a single cointegrating vector which is taken to represent the long run production function estimation of its parameters is performed using the pooled mean group estimator which allows for unrestricted short run parameter heterogeneity across countries while imposing the testable restriction of long run parameter homogeneity the long run elasticity of output with respect to the synthetic infrastructure index ranges between 0 07 and 0 10 the estimates are highly significant both statistically and economically and robust to alternative dynamic specifications and infrastructure measures there is little evidence of long run parameter heterogeneity across countries whether heterogeneity is unconditional or conditional on their level of development population size or infrastructure endowments

two sector growth models with productive public goods equilibrium in determinacy author affiliation been lon chen institute of economics academia sinica 128 academia road section 2 taipei 11529 taiwan e mail bchen econ sinica edu tw corresponding author shun fa lee department of industrial economics tamkang university 151 ying chuan road tamsui taipei county 25137 taiwan e mail alphalee mail tku edu tw acknowledgment we are grateful to two anonymous referees and an editor for constructive comments and to participants in several workshops for valuable comments and suggestions in earlier versions of the paper 1 introductionmodels of economic growth with multiple equilibrium paths offer an explanation as to why we often observe diverse growth performances among countries with similar economic environments a central question is under what conditions is it possible to establish local indeterminacy in this paper we study a lucas 1988 human capital based growth model and investigate whether there are multiple equilibrium paths and thus local equilibrium indeterminacy in the neighborhood of a balanced growth path equilibrium indeterminacy in existing two sector human capital based growth models emerges based upon two mechanisms one of the mechanisms is differential factor tax rates initiated in the work of bond wang and yip 1996 and followed by that of raurich 2001 the other mechanism is sector specific externalities pioneered in the work of benhabib and farmer 1996 in an exogenous growth model and followed by the work of benhabib meng and nishimura 2000 and mino 2001 in endogenous growth models ben gad 2003 combined the two mechanisms these two mechanisms establish local indeterminacy when the mechanisms cause the factor intensities at the social perspective and those at the private perspective to reverse the purpose of this paper is twofold first we argue that once productive public goods are considered the two existing mechanisms are not robust in creating local indeterminacy then we take into account congestion in public services so a two sector model with the two existing mechanisms can generate local indeterminacy our purpose is motivated by the following in the existing models with sector specific externalities or distorted factor taxes there is either no government spending or if the government spending is taken into account only consumptive public spending and government transfers are considered recently a number of authors have documented the positive impact of public expenditure upon the productivity of private capital 1 when there is productive public spending the production technology is externally enhanced by the public goods productive public goods as an engine of economic growth have received much attention in endogenous growth models in particular a number of studies in this line of modeling strategy have obtained local indeterminacy 2 thus it is important to determine whether or not differential factor tax rates and sector specific externalities create local indeterminacy in models with productive public goods however as we will find the two existing mechanisms no longer create local indeterminacy in a two sector growth model with productive public goods unless the difference in the factor tax rates and the gap in the sector specific externalities are implausibly large intuitively productive public goods introduce the effects of intersectoral externalities they offset the effects of the two existing mechanisms that would have otherwise reversed the factor intensity at the social viewpoint from the factor intensity at the private viewpoint as a consequence the two existing mechanisms are not robust in the establishment of local indeterminacy in models with productive public goods this paper then introduces the congestion effect in the use of public goods an effect offsetting the effect from public spending to salvage the two existing mechanisms

public investment in infrastructure in a simple growth model abstract in this paper we examine the implications for capital accumulation when infrastructure enters as an external input into private production functions in our model infrastructure is nonexclusive but may exhibit varying degrees of nonrivalry revenues from uniform taxes on capital and labor income are used to finance public investment in infrastructure we show that the optimal tax rate is independent of the degree of nonrivalry when production exhibits constant returns to augmentable factors the equilibrium displays constant growth for most parameters the growth rate depends on the population size under decreasing returns the optimal trajectory exhibits monotonic convergence to a steady state level

anticipated environmental policy and transitional dynamics in an endogenous growth model this paper makes a new attempt toinvestigate how an anticipatedenvironmental policy governs the transitionaldynamics of an economy when pollutionexternality is taken into account themodeling strategy we use is an ak technologyendogenous growth framework with an endogenousleisure labor choice it is found that unlikeinelastic labor supply framework a rise inpublic abatement expenditure will stimulate thebalanced economic growth rate it is alsofound that public abatement technology plays animportant role in determining the transitionaladjustment of the economic growth rate inresponse to a pre announced environmentalpolicy

global behaviour of a system with imperfect private public substitutability abstract empirical findings reveal that the relationship between private and public consumption generically differs from country to country it is substitutable for some while it is complementary for others the present paper incorporates this regularity into a simple growth model with public goods which affect utility and production the model casts off the standard assumption of socially constant returns to scale and as a result it generates many interesting dynamic features which do not arise with constant returns when the system displays increasing returns the dynamic path may diverge from an interior equilibrium in expanding oscillations suggesting that self fulfilling expectations could play an essential role with decreasing returns the interior equilibrium becomes a saddle point interestingly it turns out that the substitutability versus complementarity distinction does make a difference in affecting the stationary state and its transitional dynamics

bank capital regulation as an incentive mechanism implications for portfolio choice abstract this paper contrasts the conventional interpretation of prudential capital regulation as a system of ex ante enforcement hard wired with an alternative interpretation as a system of sanctions for ex post violation incentive based under the incentive based interpretation risk weightings affect portfolio choice only when assets are illiquid under both interpretations the medium term impact on portfolio allocation depends upon the relative costs of debt and equity finance viewing enforcement as incentive based suggests there is relatively less need to match risk weightings accurately to portfolio risk

the cyclicality of bank regulation in a general economic framework this article utilizes a representative agent model to address how the regulation policies for banks should respond to the general economic condition with the consideration of a self fulfilling deposit insurance facility with sufficient bank reserve to meet the expected need of liquidity shock our model suggests a counter cyclical capital adequacy requirement in a competitive loan market the exception might occur when the moral hazard problem becomes very unwieldy and the representative individual is rather risk averse with regard to the closure policy we find that it is closely related to the individual s degree of risk aversion a counter cyclical closure policy is recommended when the individual is highly risk averse otherwise a pro cyclical closure policy is preferred

bank capital and equity investment regulations abstract this paper uses an intermediation model to study the efficiency and welfare implications of both banks minimum required capital asset ratio and the regulation that limits and in some countries forbids banks investments in the equity of nonfinancial firms there are two sources of moral hazard in the model one between the bank and the provider of deposit insurance and the other between the bank and an entrepreneur who demands funds to finance an investment project among other things the paper shows that capital regulation improves the bank s stability and can also be pareto improving equity regulation is never pareto improving and does not increase the bank s stability

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

transitional dynamics in two sector models of endogenous growth the steady state and transitional dynamics of two sector models of endogenous growth are analyzed in this paper we describe necessary conditions for endogenous growth the conditions allow us to reduce the dynamics of the solution to a system with one state like and two control like variables we analyze the determinants of the long run growth rate we use the time elimination method to analyze the transitional dynamics of the models we find that there are transitions in real time if the point in time production possibility frontier is strictly concave which occurs for example if the two production functions are different or if there are decreasing point in time returns in any of the sectors we also show that if the models have a transition in real time the models are globally saddle path stable we find that the wealth or consumption smoothing effect tends to dominate the substitution or real wage effect so that the transition from relatively low levels of physical capital is carried over through high work effort rather than high savings we develop some empirical implications we show that the models predict conditional convergence in that in a cross section the growth rate is predicted to be negatively related to initial income but only after some measure of human capital is held constant thus the models are consistent with existing empirical cross country evidence authors

spill over effects of supply side changes in a two country economy with capital accumulation abstract using a two country dynamic optimization model with capital accumulation we explore the effect of such supply side changes as a rise in productivity and a reduction in the corporate tax rate on the equilibrium path and the welfare of two countries the welfare effect consists of a tax distortion term and a wealth term those supply side changes in the creditor country increase its welfare but unambiguously decrease the debtor country s welfare as capital moves from the debtor country to the creditor country

anticipated inflation in a monetary economy with endogenous growth this paper makes a new attempt to investigate the role of anticipatedmonetary growth in economic growth combining the barro 1990 rebelo 1991 type endogenous growth model with sidrauski s 1967 framework we show that the pre announcement of money supply behaviour may have significant effects on the rate of growth during the transition process the key factor indetermining adjustment patterns of the economy to anticipated monetary changes is the degree of relative risk aversion however changes in the rate of monetary growth do not affect the rate of long run growth regardless of the degree of relative risk aversion

growth versus welfare in a model of nonrival infrastructure abstract the paper constructs a model of endogenous growth where infrastructure acts as an accumulable stock generating a nonrival input service steady state growth paths are studied for market and command economies in the former a final good is produced privately and as in many developing economies infrastructure accumulated on noncompetitive basis by the state the command economy allocates resources by solving a grand optimization exercise the transitionally stable steady growth rate for the market economy dominates the command economy growth rate due to the joint presence of noncompetitive behaviour by the state and noninternalizable externalities

budget balance welfare and the growth rate dynamic scoring of the long run government budget this paper determines conditions under which a reduction in the role of government either through a tax cut alone or together with accompanying expenditure cuts will improve long run government fiscal balance for a ceteris paribus cut in the income tax rate to improve long run government balance the intertemporal elasticity of substitution must exceed unity a tax cut balanced by an expenditure cut is likely to improve the long run balance even if it does not improve the short run balance the relationship between improving the long run fiscal balance and economic welfare is also analyzed

accounting for banks capital regulation and risk taking this paper examines risk taking incentives in banks under dierent accounting regimes with capital regulation in the model the bank s decisions of capital issuance and investment policy are jointly determined given exogenous minimum capital requirement the bank is more likely to issue equity capital in excess of the minimum required level and implement less risky investment policy under either lower of cost ormarket accounting or fair value accounting than under historical cost accounting but fair value accounting may induce more risk taking compared to lower of cost or market accounting due to short term interest in the part of the bank however the disciplining role of lower of cost or market accounting may discourage bank s incentive to exert project discovery eort

infrastructure provision and macroeconomic performance this paper studies the differences between private and government provision of infrastructure capital utilization decisions and their differential role in determining market prices for capital goods under the two regimes of infrastructure provision serve as a critical transmission mechanism for fiscal policy a subsidy to private providers of infrastructure is preferable to direct government provision irrespective of how the subsidy or expenditure is financed the case for private provision is much stronger in economies characterized by high levels of congestion the choice between private and government provision also has a crucial effect on the design of optimal fiscal policy 2011 elsevier b v all rights reserved

public investment congestion and private capital accumulation this paper analyses the impact of public investment on the dynamics of private capital formation in an intertemporal optimising market clearing framework the key feature characterising the analysis is that the public good is treated as a durable capital good subject to congestion we show how in the presence of congestion the effect of government investment on private capital formation involves a tradeoff between the degree of substitution between private and public capital in production and the degree of congestion both lump sum and distortionary tax financing are considered with this tradeoff being tightened in the latter case

correlated default risks and bank regulations bank regulatory design relies critically on bank risk modeling traditionally the bank s aggregate value is assumed to obey an exogenously specified process e g a lognormal diffusion we demonstrate that this assumption is generally invalid given the truncated and correlated payoff structure of individual bank loans instead the bank s aggregate terminal payoff is significantly left fat tailed this skewness remains even when the bank holds an infinitely large number of loans in its portfolio unless they are uncorrelated by ignoring skewness in bank payoffs deposit insurance premia and capital requirements have traditionally been significantly mis calculated

using cost observation to regulate firms the paper emphasizes the use of accounting data in regulatory or procurement contracts when the supplier 1 has superior information about the cost of the project and 2 invests in cost reduction the main result states that under risk neutrality the supplier announces an expected cost and is given an incentive contract linear in cost overruns this optimal contract moves toward a fixed price contract as the announced cost decreases an investment choice is then introduced and the use of a rate of return regulation is studied

optimal fiscal policy public capital and the productivity slowdown abstract this paper develops a quantitative theoretical model for the optimal provision of public capital we show that the ratio of public to private capital in the us economy since 1925 evolves in a manner that is broadly consistent with an optimal transition path derived from a simple growth model the model is used to quantify the conditions under which an increase in the stock of public capital is desirable and to investigate the degree to which nonoptimal fiscal policies can account for the us productivity slowdown

excludable and non excludable public inputs consequences for economic growth non excludable and excludable public inputs are introduced into an endogenous growth model we derive the equilibrium growth rate and design the optimal tax and user cost structure emphasizing the role of congestion and its consequences for the government s budget the latter comprises fee and tax revenues that are used to finance the public inputs although they may generate insufficient revenue to do so entirely we extend the model to allow for monopoly pricing of the user fee by the government most of the analysis is conducted for general production functions consistent with endogenous growth but the ces technology is also considered a vast literature has evolved emphasizing the role of public investment as a determinant of economic growth among the earliest contributions arrow and kurz 1970 is particularly significant while the seminal work of barro 1990 has been especially influential with respect to the contemporary endogenous growth literature stimulated by aschauer s 1989 findings pertaining to the high rate of return on public capital several authors have explored various aspects of the role of public capital in stimulating economic growth for example baxter and king 1993 and fisher and turnovsky 1998 examine the interaction between public and private capital in a ramsey type growth model while futagami et al 1993 perform a similar type of analysis in an endogenous growth context glomm and ravikumar 1997 analyse the growth effects of productive public spending in an overlapping generations setup extending the framework to include majority voting and alternative compositions of publicly provided goods and services they also indicate private alternatives to public provision but do not pursue this in detail cassou and lansing 1998 focus on the relationship between private and public capital showing how the evolution of the ratio between the two in the us economy since 1925 is broadly consistent with the predictions of a simple ramsey growth model they also show how the productivity slowdown in the us economy since the 1970s is more likely due to increasing tax rates than to non optimal public investment policy much of the literature including barro treats the public input as a pure public good freely available without restrictions or impediments to all agents in the economy but the public goods literature identifies many different characteristics that most public goods in fact exhibit notably the presence of rivalry and or excludability see e g cornes and sandler 1996 thus the treatment of a public

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

trends in stock bond correlations abstractprevious studies document the existence of long run trends in comovements in the stock and bond markets following these findings this article examines possible trends in stock bond return correlations to this end we introduce a trend component into a smooth transition regression str model including the multiple transition variables of aslanidis and christiansen 2012 the results indicate the existence of significant decreasing trends in stock bond correlations for many advanced safer countries in addition although stock market volatility continues to be an important factor in stock bond correlations the short rate and yield spread become only marginally significant once we introduce the trend component our out of sample analysis also demonstrates that the str model including the volatility index and time trend as the transition variables dominates other models furthermore we find a significant increase in stock bond correlations for riskier euro countries around the beginning of th

dynamics of international integration of government securities markets abstract this paper investigates the dynamics of international government bond market integration in six of the g7 economies over two decades leading up to the global crisis it examines whether such integration had been significant the extent to which integration at the short and long end of the yield curve differed the nature of such integration and the extent of the decoupling of the long rates from short rates these issues are investigated using the rigorous smooth transition copula garch model framework the results show that integration at the long end of the yield curve had been increasing had become pronounced and was significantly greater than at the short end decoupling between the short and long end of the yield curve was notable with important implications for the efficacy of monetary policy in the period before the crisis

is fairly priced deposit insurance possible we analyze risk sensitive incentive compatible deposit insurance in the presence of private information and moral hazard without deposit linked subsidies it is impossible to implement risk sensitive incentive compatible deposit insurance pricing in a competitive deregulated environment except when the deposit insurer is the least risk averse agent in the economy we establish this formally in the context of an insurance scheme in which privately informed depository institutions are offered deposit insurance premia contingent on reported capital the result holds for alternative sorting instruments as well this suggests a contradiction between deregulation and fairly priced risk sensitive deposit insurance this paper exposes a conflict between a deregulated competitive financial services industry on the one hand and fairly priced risk sensitive deposit insurance on the other we show that if depository institutions dis are perfectly competitive i e each makes zero profits on average then it is impossible to implement incentive compatible risk sensitive deposit insurance pricing recent distress among dis has fueled debate about reform of the existing deposit insurance system many believe that the prevailing risk insensitive premium structure encourages dis to choose excessively risky assets and that it should be replaced by deposit insurance premia linked to the dis choices of risk 2 risk sensitive deposit insurance pricing however imposes greater informational demands on the deposit insurer and runs afoul of both

on the optimality of public capital for long run economic growth evidence from panel data the role of public capital in economic growth is examined using data from the penn world tables and other sources on a large number of countries drawing on intertemporal optimization the theoretical framework nests the exogenous solow and endogenous types of growth and is data consistent it is found that public capital makes a significant contribution to growth the actual level of investment on public capital is suboptimal growth in recent decades can be characterized as endogenous with little sign of convergence there is evidence of a growth slow down between the 1970s and 1980s human capital also significantly enhances growth

reprint to infrastructure provision and macroeconomic performance abstract this paper studies the differences between private and government provision of infrastructure capital utilization decisions and their differential role in determining market prices for capital goods under the two regimes of infrastructure provision serve as a critical transmission mechanism for fiscal policy a subsidy to private providers of infrastructure is preferable to direct government provision irrespective of how the subsidy or expenditure is financed the case for private provision is much stronger in economies characterized by high levels of congestion the choice between private and government provision also has a crucial effect on the design of optimal fiscal policy

building resilience to natural disasters an application to small developing states abstract we present a dynamic small open economy model to explore the macroeconomic impact of a major natural disaster in addition to permanent damages to public and private capital the disaster causes temporary losses of productivity inefficiencies during the reconstruction process and damages to the sovereign s creditworthiness we use the model to study the debt sustainability concerns that arise from the need to fully rebuild public infrastructure over the medium term and analyze the feasibility of ex ante policies such as building adaptation infrastructure and fiscal buffers and contrast these policies with the post disaster support provided by donors investing in resilient infrastructure may prove useful in particular if it is viewed as complementary to standard infrastructure because it raises the marginal product of private capital crowding in private investment while helping withstand the impact of the natural disaster in an application to vanuatu we find that donors should provide an additional 50 of pre cyclone gdp in grants to be spent over the following 15 years to ensure public debt remains sustainable following cyclone pam helping the government build resilience on the other hand reduces the risk of debt distress and at lower cost for donors

repeated auctions of incentive contracts investment and bidding parity with an application to takeovers this article considers a two period model of natural monopoly and second sourcing the incumbent supplier invests in the first period after observing the incumbent s first period performance the buyer may break out in the second period the investment may or may not be transferable to the second source and it may be monetary or take the form of human capital we determine whether the incumbent should be favored at the reprocurement stage and how the slope of his incentive scheme should evolve over time we find that the gains from second sourcing are not so large as one might hope finally we reinterpret the second source as a raider and the breakout as a takeover we discuss the desirability of defensive tactics and obtain a rich set of testable implications concerning the size of managerial stock options the extent of defensive tactics the firm s performance and the probability of a takeover

growth outside the stable path lessons from the european reconstruction abstract this paper exploits a natural experiment the large destruction of capital in continental europe during world war ii to characterize the transitional dynamics of an economy that begins with a capital stock below its steady state level we use these regularities as a benchmark to discriminate among competing growth specifications a model that combines non separabilities in preferences with a technology that restricts the degree of substitutability between inputs outperforms the widely used ak and cobb douglas specifications with time separable preferences our results suggest that policy evaluations based in growth models that overlook non separabilities in preferences or impose strong restrictions on the technological structure might be grossly misleading

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

factor taxation and labor supply in a dynamic one sector growth model abstract this paper studies a class of ak type growth models with factor income taxes public capital stock and labor leisure trade offs while a higher capital tax rate reduces economic growth in the short run the long term growth effect is ambiguous and remains ambiguous even if the level of tax rate is larger than the degree of government externality a higher labor income tax rate has ambiguous growth effects both in the short and long runs however if the intertemporal elasticity of substitution for labor supply is sufficiently small a higher labor tax rate always lowers economic growth in the long run despite the existence of productive government taxation

aid non traded goods and growth we examine the effects of foreign aid in a small recipient country with two traded goods one non traded good and two factors learning by doing and intersectoral knowledge spillovers contribute to endogenous growth we obtain two main results first a permanent increase in untied aid raises or lowers the growth rate if and only if the non traded good is more capital intensive or effective labour intensive than the operating traded good second a permanent increase in untied aid raises welfare if the non traded good is more capital intensive than the operating traded good otherwise it may raise or lower welfare jel classification f43 o41

optimal taxation of capital income in general equilibrium with infinite lives this paper analyzes the optimal tax on capital income in general equilibrium models of the second best agents have infinite lives and utility functions which are extensions from the koopmans form the population is heterogeneous the important property of the models is the equality between the social and the private discount rates in the long run i find that the optimal tax rate is zero in the long run for a special case of additively separable utility functions i then determine the tax rates along the dynamic path and conditions that are sufficient for the local stability of the steady state

solvency regulations and the management of banking risks abstract in the recent years international banking authorities have succeeded implementing harmonized solvency regulations however two stages can be distinguished 1 up to 1993 a rigid approach has prevailed with the cooke ratio for credit risks and the standardized approach to market risks 2 since then a movement towards flexibility has been acknowledged notably with the validation of internal models of the var type and the precommitment proposal of kupiec and o brien the objective of this article is to discuss the pros and cons of these different approaches within a coherent conceptual framework that applies contract theory to the regulation of banking

an experimental exploration of self fulfilling banking panics their occurrence persistence and prevention this article tests the possibility and the degree of persistence of self fulfilling banking panics through an experimental protocol panics are proved to be persistent phenomena that are difficult to prevent however it seems possible to curb them through a learning effect caused by a temporary but sufficient suspension of the deposit availability combined with a narrow banking solution which makes banks more liquid additionally panic prevention requires a full deposit coverage to be effective this suggests that the moral hazard issue should not be tackled through a lower deposit coverage especially in emerging countries banking systems where depositors are likely to lose confidence

bank runs deposit insurance and capital requirements diamond and dybvig provide a model of intermediation in which deposit insurance can avoid socially undesirable bank runs we extend the diamond dybvig model to evaluate the costs and benefits of deposit insurance in the presence of moral hazard by banks and monitoring by depositors we find that complete deposit insurance alone will not support the first best outcome depositors will not have adequate incentives for monitoring and banks will invest in excessively risky projects however an additional capital requirement for banks can restore the first best allocation

the composition of government expenditure and its consequences for macroeconomic performance abstract this paper employs the intertemporal optimizing market clearing framework to compare the effects of government consumption expenditure and government infrastructure expenditure on macroeconomic adjustment and performance particular attention is focused on the time path of the capital stock and its adjustment to both permanent and temporary changes in government expenditure are considered we show how the effects of both forms of government expenditure on economic welfare can be broken down into 1 i a direct crowding out effect and 2 ii a second component which describes the intertemporal tradeoffs between the short run rate of capital accumulation and the resulting change in the capital stock

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had

the growth effects of tax rates in the oecd this paper explores the merits of macro and micro based tax rate measures within an open economy fiscal policy and growth model using annual data for 15 oecd countries we find statistically small non robust long run growth effects of macro based average tax rates on capital income and consumption but some evidence for average labor income tax effects changes in micro marginal income tax rates at both the personal and corporate levels yield statistically robust gdp responses of modest size both domestic and foreign corporate taxes appear relevant in general tax effects on gdp operate largely via factor productivity rather than factor accumulation

are bank capital ratios pro cyclical new evidence and perspectives this paper analyses how the new basel iii leverage ratio and risk weighted regulatory capital ratio behave over the cycle the analysis proposes a set up to test for the cyclical properties of bank capital ratios taking into account structural shifts in banks behaviour during the global financial crisis and its aftermath using a large data set covering international banks headquartered in 14 advanced economies for the period 1994 2012 we find that the basel iii leverage ratio is significantly more countercyclical than the risk weighted regulatory capital ratio it is a tighter constraint for banks in booms and a looser constraint in recessions

dynamic analysis of an endogenous growth model with public capital this paper develops an endogenous growth model with productive public capital along with private capital in a spirit similar to that of r j barro 1990 since the authors model includes two stock variables it has transitional dynamics unlike most of the previous studies on endogenous growth including barro s where concerns are restricted to the steady state analysis first they show that the transitional path is unique and stable second the character of the transitional path is explored third the authors show that the optimal tax rate is smaller than the rate that maximizes the national growth rate with a log linear utility function copyright 1993 by the editors of the scandinavian journal of economics

market valuation of bank assets and deposit insurance in canada we examine a sample of canadian banks and use option pricing theory to infer the market value of a bank s assets from the observed market value and volatility of its equity we find that market value estimates are significantly different from corresponding book values these differences vary significantly across banks suggesting that market values provide bank specific information not found in book values we also derive that risk adjusted deposit insurance premia for these banks our results suggest that the current fixed rate deposit insurance premium system has resulted in significant
