current account dynamics and expected future budget deficits some international evidence abstract this paper addresses the question of whether current account deficits are linked to expected future budget deficits we use an optimizing general equilibrium model to show the theoretical relationship between the two deficits we then estimate the econometric equation based on the forward looking expectations model for oecd countries thus extending earlier research based on more conventional analysis from the empirical investigation evidence is obtained that strongly supports the view that current account deficits have been associated with expected future budget deficits during the 1970 1997 period

habits costly investment and current account dynamics abstract we analyze the current account dynamics for a small country model with habit forming consumers and costly investment the model has several empirical and policy implications i it is consistent with stylized facts regarding the effects of productivity shocks and increases in fiscal spending and regarding the savings investment co movement ii the long run effect of a temporary shock on net foreign assets is often opposite to that of a permanent shock iii under strong habit persistence the welfare dynamics are sluggish so that a beneficial tax financed fiscal policy may have a harmful hangover effect on welfare

liberalization of capital movements and of the domestic financial system this paper analyzes the dynamic impact of a joint liberalization of capital movements and of the domestic financial sector both a simultaneous and a sequential liberalization are examined in an overlapping generations model with a q theory of investment a liberalization generally leads to an initial period of capital inflows followed by capital outflows it also increases investment and causes an overshooting in share prices furthermore the interest rate level before a liberalization will usually not indicate the direction of net capital flows copyright 1992 by the london school of economics and political science

interpreting comovements in the trade balance and the terms of trade abstract i examine the relation between the trade balance and the terms of trade in a two country dynamic stochastic exchange economy with complete markets along an equilibrium path for this economy the relation is governed by the substitutability between foreign and domestic goods i find in contrast to non stochastic analyses of the harberger laursen metzler effect that a positive association does not require persistent shocks or non constant rates of time preference this contrast highlights the role played by the structure of asset markets complete and otherwise in generating equilibrium comovements

trade policy and income inequality new evidence abstract this paper uses recently available data to investigate the link between income inequality and trade protection it finds that among less developed countries more open economies experienced increased income inequality during the late 1980s trade policy has had no effect on income inequality in developed countries

a simple model of sectoral adjustment despite the significance of limited labour mobility across sectors few attempts have been made to produce dynamic models of sectoral adjustment which are consistent with perfect foresight and yet flexible enough to allow for a variety of dynamic experiments this paper proposes a simple perfect foresight model of two sector economies in which aggregate sectoral movement of labour takes place through the process of demographic change the model is tractable enough that one can easily examine the effects of intertemporally complicated relative price shocks both exogenous and endogenous under a variety of assumptions on technology

real and monetary cycles in models of keynes wicksell type abstract we formulate a descriptive dynamic macroeconomic model of the keynes wicksell type which incorporates goods labour and financial markets the model has well specified budget constraints with respect to the economic agents households firms and government within it we introduce some standard nonlinearities into the goods and labour markets the dynamics of the general model consist of five differential equations we analyse two and three dimensional subcases to show the existence of real and monetary cycles whose interaction will determine the full dynamics we use numerical simulation to study the dynamics of the full model and the impact of various government fiscal and monetary policies

investment tax credit in an open economy abstract this paper contrasts the effects of a permanent and temporary investment tax credit itc in an open economy in both cases an itc will initially stimulate investment while reducing employment and output and generating a current account deficit if the itc is permanent the accumulation of capital leads to a higher equilibrium capital stock higher employment and output and a reduction in the economy s stock of net credit if the itc is temporary after its removal the economy eventually moves to a new steady state equilibrium having a lower permanent capital stock and employment together with a higher stock of net credit

income distribution political instability and investment abstract this paper successfully tests on a sample of 71 countries for the period 1960 85 the following hypotheses income inequality by fuelling social discontent increases sociopolitical instability the latter by creating uncertainty in the politico economic environment reduces investment as a consequence income inequality and investment are inversely related since investment is a primary engine of growth this paper identifies a channel for an inverse relationship between income inequality and growth we measure socio political instability with indices which capture the occurrence of more or less violent phenomena of political unrest and we test our hypotheses by estimating a two equation model in which the endogenous variables are investment and an index of socio political instability our results are robust to sensitivity analysis on the specification of the model and the measure of political instability and are unchanged when the model is estimated using robust regression techniques

income effect wealth effect and the terms of trade with finite horizons the two sector model is incorporated into blanchard s olg framework the total effect of a terms of trade deterioration on aggregate savings is decomposed into an income effect and a wealth effect the income effect comes about because a terms of trade deterioration changes the value of the gdp its sign depends on the value of the rate of time preference relative to the interest rate the wealth effect comes about because financial wealth is insurable and so income from capital is discounted at a lower rate than labor income its sign depends on the relative factor intensities of the goods

the current account in the macroeconomic adjustment process macroeconomic adjustments to changes in the economic environment are to a large extent conditioned by the intertemporal choices of economic agents when agents face an intertemporal budget constraint a decision to alter current indebtedness implies changes in future consumption possibilities and will be based on expectations of the entire future path of key variables and not only current variables a formal model to show how today s current account is a function of both current and future economic variables is presented the determination of the current account under classical assumptions of market clearing and continuous full employment is emphasized

taking stock a critical assessment of recent research on inventories empirical and theoretical aspects of inventory behavior became hot topics in the 1950s and early 1960s no one seemed to notice the tension that was developing between the emerging macroeconomic and microeconomic views of inventories macroeconomists routinely thought of inventories as a destabilizing factor yet the prevailing micro theory viewed inventories as a stabilizing factor it was a fascinating question that was barely explored instead somewhat inexplicably interest in inventories dried up as if inventories were of minor economic significance and little intrinsic interest by the early 1980s then economists once again knew something they had known in the 1950s that inventory investment is of first order importance in business cycles but they were also beginning to realize that the standard production smoothing buffer stock model of inventories was in deep trouble this paper focuses on developments since that realization

central bank transparency and the volatility of exchange rates abstract we analyze the effect of monetary policy transparency on bilateral exchange rate volatility we test the theoretical predictions of a stylized model using panel data for 62 currencies from 1998 to 2010 we find strong evidence that an increase in the availability of information about monetary policy objectives decreases exchange rate volatility using interaction models we find that this effect is more pronounced for countries with a lower flexibility of goods prices a lower level of central bank conservatism and a higher interest rate sensitivity of money demand

balance of payments crises in a cash in advance economy the author shows that a flexible prices sidrauski type model with a cash in advance constraint is capable of depicting some of the phenomena associated with a balance of payments crisis like the onesrecently observed in argentina and mexico current accounts deficits and appreciation of the real exchange rat e it is also shown that these phenomena become exacerbated as the rate of devaluation before the crisis occurs becomes smaller copyright 1987 by ohio state university press

on exchange rate stabilization abstract this paper extends calvo s 1986 and obstfeld s 1985 analyses of stabilization policies through predetermined exchange rates in a few directions the graphic and analytical techniques used here make it possible to perform a variety of policy experiments under a general utility function and in the presence of a consumer durable good or under time nonseparable preferences it also shows that the dynamic process of exchange rate stabilization exhibits hysteresis effects that is the steady state behavior of the economy depends on the initial condition and a temporary stabilization policy has a permanent effect on the economy

habits and durability in consumption and the dynamics of the current account abstract a model in which consumption exhibits durability and habits develop over the flow of services provided by them is used to study current account dynamics durability leads to adjacent substitutability in consumption while habits are assumed to lead to adjacent complementarity the adjustment of the current account may be non monotonic if habit effects are dominant in the short run and durability effects in the long run then after a terms of trade deterioration we will have a current account deficit followed by a surplus the j curve in the opposite case a surplus will be followed by a deficit 1998 elsevier science b v

terms of trade shock and the current account in a monetary economy over the period 1973 81 the terms of trade of non oil developing countries deteriorated at about 2 per cent per annum this was accompanied by an increase in current account deficits in excess of 3 per cent above what they had been in the previous decade see khan and knight 1983 for a discussion these authors find the terms of trade shocks the major cause of the deficits this has led to a renewal of interest in the effects of changes in terms of trade for a small open economy the conventional wisdom first put forward by laursen and metzler 1950 and harberger 1950 emphasized the fact that a terms of trade worsening lowered real income which in turn lowered savings and worsened the current account the laursen metzler effect the recent reappraisal was initiated by obstfeld 1982 he showed in an infinite horizon optimizing framework with perfect capital mobilizing that if the discount rate was a function of the level of utility surpluses and not deficits accompany an unanticipated and permanent terms of trade worsening the long run level of the discount rate is tied down by the given world rate of interest this in turn fixes the long run level of utility the terms of trade shock tends to lower the level of utility and agents save to offset this across steady states there is only a substitution effect on the other hand if the discount rate is fixed and equal to the world interest rate then the economy adjusts to the terms of trade shock by immediately lowering real expenditure by the same amount as the decline in real income so that the current account is always balanced svensson and razin 1983 showed that in a two period framework this does not necessarily happen for the infinite horizon case they showed that if preferences were separable over time and the discount rate was increasing in instantaneous utility then obstfeld s results were indeed obtained in a two period overlapping generations model the results could be modified owing to the fact that human wealth and non human wealth are not perfect substitutes and a terms of trade shock affects these differently see matsuyama 1988 for a discussion but it is still true that an unanticipated permanent terms of trade shock has a one shot effect on the current account unless some ad hoc costs of adjustment are introduced see e g persson and svensson 1985 and matsuyama 1988 the uncertain lifetime model see e g frenkel and razin 1988 and matsuyama 1987 generates non trivial

u s deficits since world war i the tax smoothing theory suggests that deficits would respond particularly to recession temporarily high government spending and anticipated inflation my empirical estimates indicate that a relation of this type is reasonably stable in the u s since at least 1916 in particular the statistical evidence does not support the idea that there has been a shift toward a fiscal policy that generates either more real public debt on average or that generates larger deficits in response to recessions further the deficits for 1982 3 and popular projections formed in 1984 for 1984 5 are consistent with the previous structure the high values of these deficits reflect the customary response to substantial recession interacting with big government and to expected inflation

government size government debt and globalization this article empirically investigates the effect of globalization on government size and debt using panel heterogeneous cointegration techniques to a panel of developing and developed countries i

aggregate spending and the terms of trade is there a laursen metzler effect this paper investigates the spending and current account effects of terms of trade shifts in a model where households maximize utility over an infinite planning period in the framework developed here an economy specialized in production must experience a fall in aggregate spending and a current surplus as a result of an unanticipated permanent worsening in its terms of trade the paper s model thus provides a setting in which the current account deficit predicted by laursen and metzier harberger and others fails to materialize

current accounts in the long run and the intertemporal approach a panel data investigation this paper is a theory based study of the long run determinants of the current account ca for many oecd economies after the second world war there has been more long run variation in the ca data than is emphasised by a permanent income version of the intertemporal approach that is based on consumption smoothing and that allows only transitory ca imbalances a theoretical model of the ca is developed based on the broader variant of the intertemporal approach that stresses the long term component of the ca we find that some key theoretical predictions hold while others fail validating the approach but also pointing to its limitations

a keynes goodwin model of the business cycle abstract the paper puts forward a dynamic is lm model in four state variables representing real balances inflation income distribution and a so called state of confidence local in stability is characterized by high low interest elasticities of money demand also a hopf bifurcation can be shown to exist freezing inflation and distribution makes a mathematical analysis of the main stability mechanisms in the outer regions possible the global dynamics of the full system is studied by means of numerical simulations it gives rise to unique and stable limit cycles lastly a sensitivity analysis inquires into the impact of parameter changes on the main cycle features

imported input price and the current account in an optimizing model without capital mobility abstract this paper analyses the effect of an oil price increase in an economy which cannot borrow in the international capital markets current account surpluses and deficits are matched by reserve changes at the central bank it is shown in an optimizing setup that an unanticipated oil price increase worsens the current account and lowers the real interest rate contrary to models which assume perfect capital markets

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

public sector deficits and macroeconomic performance in the 1980s chronic public sector deficits forced countries to undertake fiscal adjustment the need to face hard choices continues in the 1990s but the problem is not a simple and easily diagnosed one with an obvious solution rather public sector deficits have had widely differing consequences high inflation in some countries low inflation but also low investment and growth in others and in still others no evident short term macroeconomic spillovers this book presents the findings of a world bank research project designed to shed light on the complex dynamics of public sector deficits it includes an in depth examination of eight countries argentina chile colombia cote d ivoire ghana morocco pakistan and zimbabwe these cases are analyzed within a comprehensive theoretical framework elaborated for the study and in conjunction with cross country data from a larger set the book draws the following conclusions the ways chosen to finance deficits money creation debt or arrears go far to explain medium term financial and macroeconomic imbalances but in the short term these relations are blurred deficits tend to be bad for growth they increase financial and price instability and crowd out private investment public saving typically reduces private saving only slightly increasing public saving is a very effective policy instrument for raising national saving fiscal adjustment typically leads to a lower trade deficit and a moredepreciated real exchange rate finally the blame for large systemic public deficits must be placed not on bad luck but on unwise policy choices and conversely sound fiscal policies can set a country on a path leading to stability and growth

current account dynamics and the terms of trade harberger laursen metzler two generations later this is a study of the current account dynamics resulting from the savings and investment dynamics in a small open economy which is subject to exogenous changes in its terms of trade and in world interest rates anticipated and unanticipated as well as temporary and permanent terms of trade changes have very different effects there is however a general tendency towards cycles in both savings and investment which gives rise to cycles in the current account it is shown that the classic harberger laursen metzler effect on saving of a terms of trade deterioration can have any sign for plausible parameter values both for temporary and permanent disturbances

eliminating interest taxation and tariffs the underpinnings for recent canadian policy blanchard s 1985 formulation of the overlapping generations model and the so cial welfare function advocated by calvo and obstfeld 1988 are used to analyse interest taxation and tariffs in a small open economy when the revenue lost from the elimination of these taxes is replaced by raising the tax on labour as in recent canadian experience a low social discount rate is required for the model to support lower interest income taxes while a high discount rate is needed to support the elimination of tariffs we illustrate the empirical importance of this simultaneous need for both a high and a low discount rate eliminer l imposition des revenus d interet et les droits de douane les soubassements de la politique canadienne re cente les auteurs utilisent la formulation blanchard du modele des generations qui se chevauchent et la fonction de bien etre social de calvo et obstfeld pour analyser les effets de l imposition des revenus d interet et des droits de douane dans une petite economie ouverte quand la perte de revenus attribuable a l elimination de ces taxes est comblee par un imp6t sur le travail comme ce fut le cas au canada il faut postuler un taux d escompte social bas pour qu on puisse endosser une politique de reduction de l imposition des revenus d interet alors qu il faut postuler un taux d escompte social eleve pour endosser une politique de reduction des droits de douane les auteurs montrent l importance empirique de cette necessite d avoir un taux d escompte a la fois bas et haut

deterioration of the terms of trade and capital accumulation a reexamination of the laursen metzler effect abstract this paper analyzes the effect of both a permanent and a temporary deterioration in the terms of trade on a small open economy the model based on intertemporal optimization emphasizes the labor leisure choice and the role of capital accumulation the transitional dynamics is shown to depend upon the long run response of the capital stock to the terms of trade shock this consists of a negative substitution effect together with a positive income effect whether or not the laursen metzler effect holds depends upon whether the income effect dominates the substitution effect

the voracity effect abstract we analyze an economy that lacks a strong legal political institutional infrastructure and is populated by multiple powerful groups powerful groups dynamically interact via a fiscal process that effectively allows open access to the aggregate capital stock in equilibrium this leads to slow economic growth and a voracity effect by which a shock such as a terms of trade windfall perversely generates a more than proportionate increase in fiscal redistribution and reduces growth we also show that a dilution in the concentration of power leads to faster growth and a less procyclical response to shocks jel f43 o10 o23 o40

dynamic analysis of policy lag in a keynes goodwin model stability instability cycles and chaos abstract in this paper we investigate the impact of government s stabilization policy on the dynamic behavior of the economic system in an analytical framework of a keynes goodwin model of the growth cycle in particular we study the effects of the policy lag on macroeconomic stability analytically and numerically it is shown that the increase of the policy lag contributes to destabilize the system and cyclical behavior and chaotic motion emerge in some ranges of the parameter values

the harberger laursen metzler effect under capital market imperfections abstract this paper re examines the effects of a permanent terms of trade change on a dynamic small open economy facing an imperfect world capital market as studied in obstfeld 1982 aggregate spending and the terms of trade is there a laursen metzler effect quarterly journal of economics 97 251 270 which assumes that the economy faces a downward sloping bond curve the novelty of the present paper is that a saddle path stable steady state comes into existence under the assumption that households subjective discount rate is a decreasing function of instantaneous utility the harberger laursen metzler hlm effect is shown to hold unambiguously i e an unanticipated permanent terms of trade deterioration leads to an increase in aggregate expenditure and a current account deficit this result is in stark contrast to those obtained in obstfeld 1982 aggregate spending and the terms of trade is there a laursen metzler effect quarterly journal of economics 97 251 270 and many other studies in the literature

the growth and welfare consequences of differential tariffs this paper analyzes the impact of differential tariffs on consumption and investment in a specific factors model of a small open economy in which capital is accumulated over time particular attention is devoted to the welfare aspects highlighting the cost of the intertemporal distortions produced by protective trade policies several specific welfare propositions are obtained first tariff protection is shown to create short run benefits but long run costs in welfare second the second best policy for the two tariffs is characterized finally several propositions summarizing the implications of our analysis for tariff reform are derived

some macroeconomic effects of nationalizing private sector foreign debt abstract in the recent debt crisis years many governments have adopted foreign debts of their domestic private sectors this paper uses a simple small open economy version of blanchard s 1985 overlapping generations model to demonstrate that such a policy encourages the accumulation of national foreign debt and can contribute to higher inflation because individuals have finite lives they fail to fully internalize the government s intertemporal budget constraint current generations therefore regard the debt relief as an increase in wealth they raise consumption which causes current account deficits future generations have to lower consumption to service the additional debt the debt service takes the form of a higher inflation tax if the government tries to stabilize exchange rates while nationalizing debt both the debt and inflation problems are exacerbated

international transmission of monetary and fiscal policy abstract this paper analyzes the effects of monetary and fiscal expansion on the multiple economies in a dornbusch model and a yaari blanchard model unlike previous literature the paper incorporates union and explicitly solves the n country models the effects of monetary and fiscal expansion outside the union are quite similar to the previous results based on the two country models however the effects of expansion inside the union induce a different dynamic path after the policy changes furthermore the number of union members changes the fluctuations of various endogenous variables

inventory fluctuations in a disequilibrium macro model as fig i shows this pattern continues to hold with remarkable fidelity over the postwar period as well notice that stock levels tend to peak during recessions shaded areas and to trough shortly after recessions while the stock sales ratio tends to peak during the latter part of recessions and to trough during expansions given the huge role played by stocks in business fluctuations 1 it is surprising that so little theoretical attention is directed toward improving our understanding of the timing of stock and stock sales ratio movements 2 the purpose of this paper is to offer a theoretical model which is consistent with the observed cyclical behaviour of stocks and the stock sales ratio the present model has firms forming sales expectations and then producing enough output if possible to cover the expected sales and to maintain a given stock expected sales ratio trade takes place out of equilibrium and inaccurate sales expectations or capacity constraints give rise to involuntary stock changes we find that stock holding may or may not be destabilising if stocks are not destabilising the familiar keynesian multiplier will obtain though the path of output after a shock will differ from the keynesian path if stocks are destabilising the system is found to enter a cycle with stocks and output ultimately rising and falling in a pattern much like that observed in actual cycles

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

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

accumulation and growth in a two country model a simulation approach abstract this paper analyzes saving and capital accumulation in a two good growth model of two market economies in which economic agents optimize with perfect foresight the goal is to present a model in which short run dynamics and the steady state are soundly integrated we stress the importance of asset markets as the linkage that transmits disturbances both internationally and intertemporally while many components of the model described below can be found in the literature on optimal consumption investment and international growth models we provide a consistent synthesis our framework permits the analysis of structural adjustment in the global economy and the dynamic effects of a wide range of public policies

government spending interest rates prices and budget deficits in the united kingdom 1701 1918 abstract the british data from the early 1700s through wwi provide an unmatched opportunity for studying temporary changes in government purchases temporary increases which appeared mainly as wartime spending raised long term interest rates but significantly increased the growth rates of money and prices only during suspensions of the gold standard 1797 1821 and 1914 1918 temporary changes in military spending accounted for the bulk of budget deficits over the sample of more than 200 years i found only two major non war deficits one associated with compensation payments to slaveowners in 1835 1936 and the other with a dispute over the income tax in 1909 1910 interest rates did not react much to these exogenous deficits

the necessity of delaying economic adjustment abstract i give an explanation for why agents react with a delay to decision and expectation parameters by showing that imperfect agents must adjust very slowly relative to optimally adjusting agents if they begin reacting as soon as the latter agents would react the results follow from the hypothesis of imperfect choice alone irrespective of whether there are any information search transaction or other costs of adjusting decisions the results thereby provide a general reason for observing inertially lagged behavior and also agree with recent asset market experiments whose dynamics are governed by adaptive rather than rational expectations

income distribution factor endowments and trade openness abstract this paper studies the empirical links among factor endowments trade and personal income distribution by using panel data we show that land and capital intensive countries have a less equal income distribution while skill intensive countries have a more equal income distribution we also show that the effects of trade openness on inequality depend on factor endowments in a way consistent with several recent case studies but not with the simple hecksher ohlin framework our results are robust to the division of the sample according to level of income the inclusion of different regressors the use of different measures of trade openness and of relative factor abundance and tests for possible problems of endogeneity

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

current account dynamics in a finite horizon model abstract this paper examines the response of the current account in a small open economy to a permanent change in the price of imported intermediate goods to do so it extends blanchard s 1985 open economy model to incorporate the capital stock with adjustment costs a la hayashi 1982 a price increase in imported intermediate goods can be viewed as a combination of transfer payments abroad and capital taxation the former effect leads to a current account deficit and the latter leads to a current account surplus the overall effect depends on the relative magnitude of these effects

high order disequilibrium growth dynamics theoretical aspects and numerical features abstract we investigate an open monetary growth model with sluggish prices and quantities the model combines the dynamics of rose s employment cycle and metzler s inventory cycle with internal nominal dynamics of tobin and external nominal dynamics of dornbusch type implying eight laws of motion four for the real sector and four for the nominal part these intrinsically nonlinear 8d dynamics are asymptotically stable for low adjustment speeds of prices and expectations give rise to hopf bifurcations as adjustment parameters are increased and explosive behavior thereafter extrinsic nonlinearities are therefore added one in capital flows and one in wage behavior these nonlinearities modify the dynamics radically limiting them to domains with economically plausible outcomes also for extreme parameter choices where the dynamics may become chaotic

explaining fiscal policies and inflation in developing countries abstract in this paper we investigate empirically the determinants of inflation seigniorage and fiscal deficits in developing countries we first test the optimal taxation theory of inflation for a group of 21 lcds we find that the implications of this theory are rejected for all these countries we then proceed to implement a number of tests based on the new political economy approach to macroeconomic policies we deal with some of the implications of a credibility and reputation model and of a strategic government behavior model we find that the data support the most important predictions of the political economy view of fiscal policy our measures of political instability and political polarization play an important role in explaining cross country differences in seigniorage inflation government borrowing and fiscal deficits we end by discussing directions for future research

foreign exchange liberalization and the viability of a fixed exchange regime abstract this paper investigates the effect of liberalization of capital account transactions on the viability of a fixed exchange regime using a finite time horizon model a la blanchard the paper demonstrates a case where removal of restrictions on capital outflows alone can cause a balance of payments crisis in the absence of any other external shocks the increased burden of debt service as well as the dynamics of the economy after liberalization are identified as potential sources of reserve outflow the paper also discusses the dynamics of the economy when liberalization is expected to force the central bank to give up exchange rate pegging

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

non linear structure of a metzlerian inventory cycle model abstract this study considers optimizing behavior of an inventory holding firm its main purpose is to investigate a consistent microeconomic foundation of the non linear macrodynamic model that generates inventory cycles it solves present value maximization problems under two different specifications of expectation formations one is specifying expectation formation independently of the optimizing process of the firm i call it a myopic perfect formation of expectation the other is incorporating the expectation formation in the optimizing process i call it a dynamic perfect formation of expectation the analysis demonstrates that the firm with the myopic perfect formation can posses sufficient nonlinearity for generation of cyclical macrodynamics whereas the firm with the dynamic perfect formation cannot these results suggest that the myopic perfect treatment of expectations of economic agents can be a source of macro fluctuations like inventory cycles

terms of trade shocks in africa are they short lived or long lived abstract this paper examines the persistence of shocks to the terms of trade using annual data on 42 sub saharan african countries for the period 1960 96 instead of using unit root tests to distinguish between stationary and random walk processes for the terms of trade this paper characterizes the persistence of shocks using point and interval estimates of the half lives of terms of trade shocks using median unbiased mu estimation techniques that remove the downward bias of standard least squares ls estimators we find that the cross country average of the half lives of terms of trade shocks is about 6 years it is also found that the estimated persistence of african terms of trade shocks varies widely for about one half of the countries their half lives are short lived less than 4 years while for one third of the countries their half lives are long lived permanent the majority of african countries are found to have terms of trade that typically experience finitely persistent transitory shocks which is consistent with the reversion of terms of trade to their long run trends

adaptive expectations and perfect foresight in a nonlinear metzlerian model of the inventory cycle it has long been known that the motions of aggregate inventory investment are an important facet of the business cycle see e g blinder and maccini 1991 some elementary insights into the dynamic feedback effects between inventories production and sales were provided by metzler 1941 in a small theoretical model the present note adopts his framework but seeks to overcome the limitation of its linear specifications our basic idea corresponds to the concept of a flexible inventory accelerator while metzler postulated that desired inventory investment in discrete time is equal to the gap between desired and actual stocks of inventories some later studies have introduced a constant proportionality factor for the adjustment of inventories here we go one step further and hypothesize a variable stock adjustment speed as it turns out fast adjustments in a vicinity of the stationary equilibrium cause local instability but if for

external and budget deficits in some developing countries abstract this paper documents and explains the positive comovement between the external and budget deficits of developing countries for which post 1960 time series data are available first the estimates indicate that the empirical covariance between these deficits is always positive and is statistically significant for many cases second the empirical covariance is close to that predicted from a tractable small open economy overlapping generation model with heterogeneous goods capturing the joint behavior of the external and budget deficits also the predicted covariance is induced by shocks which are closely related to internal conditions such as domestic resources and fiscal policies and to a much lesser extent to external conditions such as the world interest rate real exchange rate and terms of trade

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

tariffs and sectoral adjustments in an open economy abstract this paper analyzes the impact of a tariff on sectoral adjustments in an economy which produces two traded consumption goods one of which is exported and one nontraded investment good the importance of sectoral capital intensities is emphasized in particular the qualitative dynamic adjustment depends upon the relative capital intensities of the import competing consumption good sector and the nontraded investment good sector sectoral labor allocation effects are analyzed and the long run effect on aggregate capital accumulation is shown to depend upon the relative capital intensities of the import and export sectors temporary as well as permanent tariffs are discussed

are windfalls a curse abstract a puzzling feature of temporary terms of trade booms is that some countries have responded to such windfalls by running current account deficits furthermore those countries that ran current account deficits failed to attain greater post boom growth rates indicating the deficits were consumed or invested in low quality projects the point we make is that the structure of the fiscal process is critical in determining outcomes if fiscal control is unitary then the consumption smoothing effect is operative and representative agent models of the current account have predictive power however if control is divided among several fiscal claimants a voracity effect appears which counteracts the consumption smoothing effect leading to a deterioration of the current account in response to a positive temporary shock we model the interaction among fiscal claimants as a dynamic game and show that in equilibrium aggregate appropriation increases more than the windfall itself this results in a deterioration of the current account we also show that all the windfall is dissipated with the country experiencing no increase in welfare 1998 elsevier science b v

an optimizing analysis of the effects of world interest disturbances on the open economy term structure of interest rates abstract this paper studies the effects of world interest rate disturbances on the real domestic term structure of interest rates an intertemporal optimizing representative agent framework with variable employment and endogenous terms of trade is developed the economy faces an external borrowing constraint the adjustment of the short and long term rates as well as the discount bond yield curve is distinguished with the long rate and the yield curve derived recursively from the short both permanent and temporary world interest shocks are considered a notable result is that the yield curve exhibits relative maxima and minima for temporary disturbances

capital income taxation in a growing open economy abstract the paper studies the dynamic macroeconomic effects of various forms of capital income taxation in a model of a small open economy with perfect mobility of financial capital and intertemporal optimization on the part of households and firms one of the noteworthy results is that the introduction of a low corporate income tax will not affect consumption in the long run but will simply lead to a replacement of shares by foreign financial assets in household portfolios it is also found that an anticipated investment tax credit can have and that an anticipated dividend tax will have contractionary effects on investment before they are introduced moreover it is shown that while an unanticipated dividend tax is neutral with respect to investment it will have real effects on consumption and net foreign assets in a growing economy

oil prices welfare and the trade balance the paper examines welfare effects and the trade balance response to changes in the world oil prices and interest rates for a small oil importing economy the trade balance is mainly seen as the difference between saving and investment and these are derived from intertemporal optimization it is shown that the welfare effects consist of static terms of trade effects intertemporal terms of trade effects and employment effects the trade balance deteriorates for temporary oil price increases whereas its response is ambiguous for permanent oil price increases for a fall in the world interest rate the trade balance deteriorates if the economy is a net borrower

current account determination with traded capital goods abstract a model of real current account determination in a small open economy with many final goods sectors and traded capital goods is presented the model emphasizes the ambiguity of investment response and encourages sector specific empirical methods

capital income taxation and the current account in a small open economy abstract this paper analyzes the effects of capital income taxation on the current account noting the difference between two international tax rules the residence principle and the source principle an increase in the residence tax rate reduces foreign asset holdings in the long run and creates a current account deficit on the other hand an increase in the source tax rate increases long run foreign asset holdings because the king fullerton 1984 effective tax rate responds positively to the increase in both taxes it does not predict the effects of taxation on the direction of international capital investments

dynamic analysis in the viner model of mercantilism abstract this paper models the central theme of mercantilism in jacob viner s interpretation power vs plenty in a framework of modern theory of international finance it is shown that in the viner model of mercantilism a nation with strong mercantilist sentiment ends up with large foreign asset accumulation and high consumption in the long run an import tariff leads to more foreign asset holding and more total consumption furthermore in the viner model the harberger laursen metzler effect exists unambiguously a permanent terms of trade deterioration causes a current account deficit in the short run

current accounts in debtor and creditor countries the authors reexamine a classic question in international economics what is the current account response to a transitory income shock such as a temporary improvement in the terms of trade a transfer from abroad or unusually high production to answer this question they construct a world equilibrium model in which productivity varies across countries and international borrowing and lending take place to exploit good investment opportunities despite its conventional ingredients the model generates the novel prediction that favorable income shocks lead to current account deficits in debtor countries and current account surpluses in creditor countries evidence from thirteen oecd countries broadly supports this theoretical prediction

can inventory chaos be welfare improving abstract this study demonstrates the possibility that chaotic fluctuations may be preferable to a steady state for this purpose it uses a simple macro disequilibrium model in which inventory can be chaotically fluctuated in such a model the profit of a firm as well as the utility of a consumer fluctuates this raises the question of their average profitability and preferability in the long run this study with the aid of numerical examples demonstrates that the long run average profit can be greater than the profit obtained at the steady state while the long run average utility is the same as the utility obtained at the steady state

crowding out in open economies results from a simulation study it has recently been shown that industrialized countries in the 1970s and 1980s are characterized by a high correlation between national saving and investment this regularly is considered puzzling in the context of highly integrated international capital markets in this paper the author shows that both the failure of real interest parity and productivity changes are each sufficient to generate a high positive correlation between national saving and investment these results indicate that it is easier than previously thought to reproduce a high correlation between saving and investment in models with perfect capital mobility

how does trade openness influence budget deficits in developing countries abstract this paper analyses the effects of trade openness on budget balances by distinguishing the effects of natural openness from those of trade policy revealed indicators of natural openness and trade policy are computed using gmm system estimator the econometric analysis focuses on 66 developing countries over 1974 98 the results show that trade openness increases a country s exposure to external shocks this enforces the negative impact on budget balances of terms of trade instability additionally trade openness influences budget balances through several other channels corruption income inequalities etc then natural openness and trade policy have opposite effects the former deteriorates budget balances whereas the latter enhances them

the exact timing of the collapse of an exchange rate regime and its impact on the relative price of traded goods as of february 28 1983 ninety four countries are classified as having a fixed exchange rate regime 38 are pegged to the u s dollar 13 to the french franc 14 to the special drawing right and 24 to different baskets of currencies the choice of a fixed exchange rate peg implies a specific monetary discipline namely monetary growth equal to the growth rate of the currency or currencies to which a country is pegged monetary policy is thus subject to an exchange rate rule rather than to either a monetary growth rule or alternatively to discretionary policy a fixed exchange rate is a specific case of an active crawling peg where the preannounced rate of change in the exchange rate is zero active crawling peg rules whereby the exchange rate is adjusted downward by a preannounced amount over a specified period of time have been practiced in various places particularly in latin america recent experiments include argentina beginning december 1978 brazil during the 1980 calendar year chile from february 1978 to june 1979 jamaica from may 1978 to may 1979 portugal from august 1977 to june 1979 and uruguay beginning october 1978 1 at times the prean

commodity prices and growth in africa a frican economies export primary commodities and most export little else policymakers as well as economists and historians of african economic development have seen these exports as both a hope and a curse the following parable tells the story once upon a time a servant of the ruler discovered a miraculous plant which grew readily in that country and whose seeds could be woven into fine cloth so desirable was this fabric that it became prized all over the world and fetched a high price after two score years the plant accounted for most of the country s trade with the world the ruler ordered the peasants to grow the plant paid them only a fraction of its price and he and his nobles became fabulously wealthy because the ruler wished to be remembered as a great ruler and as the father of his country he used his wealth to build a great army and brought machines from foreign countries to make the fine goods that previously could only be obtained from foreign merchants but the machines often broke down and the goods that they made were of poor quality and after the ruler died they were left to rust under the ruler s successor there was a war in a foreign land where the plant also grew so that there was a great shortage and its price increased threefold in only three seasons the new ruler spent his newfound riches on fantastic extravagance while immense sums were expended on public works after the manner of the east and on productive works carried out in the wrong way or too soon not even the threefold increase in prices could support these expenditures and the country soon found itself deeply in debt when the war ended and the price fell the country could no longer pay the interest on its debt or borrow more money even after it had sold its only useful public work to a foreign power so that power sent a mission to the country the publication of whose report from which the above

an empirical analysis of excess interbank liquidity a case study of pakistan we investigate the drivers of excess interbank liquidity in pakistan using the autoregressive distributed lag approach on weekly data for december 2005 to july 2011 we find that the financing of the government budget deficit by the central bank and nonbanks leads to persistence in excess liquidity moreover we identify a structural shift in the interbank market in june 2008 before june 2008 low credit demand was driving the excess liquidity holdings by banks after june 2008 banks precautionary investments in risk free securities drive excess liquidity holdings monetary policy is less effective if banks hold excess liquidity for precautionary reasons

current account effects of a devaluation in an optimizing model with capital accumulation abstract this article explores the consequences of a devaluation in the context of a real optimizing model of a small open economy what provides for real effects of the devaluation is the existence of nominal wage stickiness during a contract period we show that if this contract period is relatively short the devaluation is bound to improve the current account on impact whereas this will deteriorate in the case of a long contract period and the more so the smaller are adjustment costs in investment in addition we study the consequences for the terms of trade and for the stocks of foreign assets and of capital

capital controls and international trade finance abstract this paper studies the effects of prohibiting individuals from holding foreign assets but of allowing firms to trade in foreign assets only up to what is needed to finance export and import activities although firms can perform arbitrage between domestic and foreign financial markets the distortions in asset markets are not fully arbitraged away but instead are transmitted to domestic goods markets the dynamics and steady state responses to a variety of shocks are crucially affected by capital controls even in the presence of capital controls the volatility of domestic interest rates can be substantial

what drives private saving around the world the authors investigate the policy and non policy factors behind saving disparities using a large panel data set and an encompassing approach including several relevant determinants of private saving they extend the literature in several dimensions by 1 using the largest data set on aggregate saving assembled to date 2 using panel instrumental variable techniques to correct for endogeneity and heterogeneity 3 performing robustness checks on changes in estimation procedures data samples and model specification their main empirical findings a private saving rates show considerable inertia are highly serially correlated even after controlling for other relevant factors b private sector rates rise with the level and growth rate of real per capita income so policies that spur development are in indirect but effective way to raise private saving rates c predictions of the life cycle hypothesis are supported in that dependency ratios generally have a negative effect on private saving rates d the precautionary motive for saving is supported by the finding that inflation conventionally taken as a summary measure of macroeconomic volatility has a positive impact on private saving holding other facts constant e fiscal policy is a moderately effective tool for raising national saving f the direct effect of financial liberalization are largely detrimental to private saving rates greater availability of credit reduces the private saving rate financial depth and higher real interest rates do not increase saving

buffer stocks and naive expectations in a non walrasian dynamic macromodel stability cyclicity and chaos in their pioneering work honkapohja ito 1980 constructed a non walrasian macromodel with inventory dynamics some of their assumptions are modified in this paper e g the expected demand for goods is defined by previous rather than actual demand the modified model yields results which are both similar and dissimilar to those of honkapohja and ito for example the keynesian unemployment equilibrium remains invariant but the corresponding stability condition becomes milder the chaotic behavior of the unstable systems is also analyzed

gradual wage price adjustments labor market frictions and monetary policy rules abstract in this paper the role of different types of labor market frictions in the dynamics of output and inflation is investigated for this purpose the keynes goodwin model discussed in chen et al 2006 and franke et al 2006 is extended by a labor search and matching module along the lines of mortensen et al 1994 after estimating the resulting model with u s aggregate time series and comparing its dynamics with those of a var model the performance of different types of monetary policy rules for inflation and more generally for macroeconomic stability is analyzed
