budget deficits stability and the monetary dynamics of hyperinflation hyperinflationary processes usually occur in countries with extremely large budget deficits in models of inflationary finance with rational expectations e g buiter 1987 large budget deficits cannot lead to hyperinflation the purpose of this paper is to reconcile the standard theoretical model with the stylized facts it shows that by introducing a lag in the adjustment of the money market into the standard inflationary finance model large budget deficits are indeed the main reason for hyperinflation the paper also provides an explanation for the ineffectiveness of moderate reductions in the deficit in reducing inflation and argues that fiscal lags can be destabilizing copyright 1989 by ohio state university press

money demand and seigniorage maximizing inflation conventional estimates of the seigniorage maximizing inflation rate often make use of the cagan form which implies a constant semielasticity of money demand with respect to inflation this paper shows that the elasticity of substitution in transactions between money and bonds determines how the inflation semielasticity of money demand changes as inflation rises allowing for a variable semielasticity estimates of seigniorage maximizing inflation for a panel of eleven high inflation countries are lower than those obtained by using the cagan form estimates based on the correct measure of the opportunity cost of money also differ sharply from those obtained when using conventional inflation measures copyright 1995 by ohio state university press

theoretical approaches to monetary disinflation abstract during the 1980s many countries adopted tight monetary policies to reduce high inflation rates which were the legacy of the 1970s as inflation threatens to rise at the beginning of this decade this paper provides a survey of the 1980s literature which sought to provide theoretical understandings of how monetary disinflation is achieved four models are presented monetarist neo keynesian new classical and post keynesian each model s explanation of the recession which accompanies the monetary disinflation is outlined as well as possible policy measures to reduce the extent of the recession and to hasten the return to full employment

korean inflation during the us military administration of 1945 1948 a further analysis this paper investigates the dynamic process of korean inflation under the us military administration using a structural vector autoregression svar incorporating cointegration relations among the variables the results show that government expenditure shocks are primarily responsible for price movements together with money demand shocks having noticeable short run impacts the study also shows that government expenditure shocks are the most important source of fluctuations in each of the other variables investigated the paper concludes that a reform of fiscal and monetary system is necessary to stop the sustaining process of inflation as well as fluctuations in other macro variables

interest rates and the exchange rate a non monotonic tale abstract for over 30 years the empirical international finance literature has been unable to detect a clear systematic relationship between interest rates and the nominal exchange rate we take a fresh look at the data and uncover a new stylized fact for a cross section of countries the relationship between the exchange rate and short term interest rates is non monotonic small increases in the nominal interest rate appreciate the currency whereas larger increases depreciate the currency we develop a model that explains this stylized fact based on the interaction of three effects higher interest rates increase money demand and hence appreciate the currency but also raise the fiscal deficit and depress output both of which tend to depreciate the currency we provide cross country evidence for the presence of these effects in the data

inflationary finance in an open economy abstract models of inflationary finance that consider trade and capital flows generally conclude that openness curtails the ability of governments to impose the inflation tax due to currency substitution this paper models two channels that allow central banks to increase inflation tax revenue by opening the economy first central banks can open the capital account subject to a reserve requirement on capital inflows revenue maximization produces a smaller reserve requirement on foreign capital inflows that on domestic deposits second central banks can impose prior import deposits to broaden the monetary base in order to use the inflation tax on imports as an alternative to tariff revenue

assessing the impact of financial liberalisation on stock market volatility in selected developing countries this article argues for the importance of measuring stock market volatility following financial liberalisation in developing countries three alternative indices for measuring volatility are developed these are used to examine the view that financial liberalisation induces increased asset price volatility based on the limited data available this view is corroborated in the majority of countries investigated

do surges in international capital inflows influence the likelihood of banking crises this article asks whether capital inflows bonanzas increase the probability of banking crises and whether this occurs through a lending boom mechanism results indicate that bonanzas more than triple the odds of a crisis raising its probability to 14 from an unconditional probability of 4 this effect exists in the absence of a lending boom and is found in both net and gross inflows bonanzas this effect is driven by portfolio equity and debt flows while the effect of debt is channelled through excessive lending the effect of portfolio equity flows is present even in the absence of a lending boom

time consistent collection of optimal seigniorage a unifying framework this paper reviews the existing literature on the time consistency problem of seigniorage collection when monetary policy is determined by optimal taxation considerations it develops a unifying accounting framework and suggests a general measure for seigniorage which encompasses the standard measures employed in the literature in addition the ex ante optimal solution to the optimal taxation problem is derived and interpreted in relation to the ramsey principle we show that the different recommendations of the public finance literature i e the friedman rule of optimal deflation moderately positive inflation and seigniorage maximizing inflation are specific solutions to the optimal taxation problem the paper continues with a formal illustration of the time consistency problem of the ex ante optimal policy and the characterization of the time consistent solution under discretion as possible solutions to the time consistency problem we consider reputational forces institutional reforms that establish central bank independence and specific ways of asset and debt management in particular it is formally shown that a modified version of the asset and debt management scheme suggested by persson persson and svensson is not only necessary but also sufficient for optimality although this did not hold in their model

sharing a ride on the commodities roller coaster common factors in business cycles of emerging economies fluctuations in commodity prices are an important driver of business cycles in small emerging market economies emes this paper documents how these fluctuations correlate strongly with the business cycle in emes a commodity sector is then embedded into a multi country emes business cycle model where exogenous fluctuations in commodity prices follow a common dynamic factor structure and coexist with other driving forces the estimated model assigns to commodity shocks 42 percent of the variance in income of which a considerable part is linked to the common factor a further amplification mechanism is a spillover effect from commodity prices to risk premia

government expenditure and the dynamics of high inflation abstract this paper develops a dynamic model of inflation where the money supply is determined by the government s use of newly created money to finance its budget deficit in turn the government s deficit is influenced by past inflation rates that reduce the real value of tax receipts while the money supply and the budget deficit are modeled as endogenous government expenditure is assumed to be exogenously determined by the policymaker changes in fiscal policy are allowed by modeling expenditure as an autoregressive process subject to discrete switches in regime agents are conjectured to have access to a larger set of information than the researcher this additional information is incorporated in the rate of inflation through the agents money demand decision the econometrician constructs probability assessments concerning the regime of the spending process at every point in time and refine his her inferences by exploiting the structural relationship between inflation money growth and government expenditure

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

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

a firm level chronicle of financial crises in the southern cone abstract this paper chronicles the recent emergence of financial crises in the southern cone countries of south america relying on firm level panel data major changes in the macro and regulatory environments are linked to changes in firms earnings streams and financial structures for each country a boom phase a squeeze phase and a bust phase are identified it is argued that the proximate cause of this pattern was wild fluctuation in the expected real return on financial assets though no formal model is developed it is suggested that these swings were due to the system of incentives created by rapid banking sector deregulation cum exchange rate based stabilization policies

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

government revenue from monopoly supply of currency and deposits abstract this paper analyses the revenue maximising problem for a government with a monopoly over the entire money industry i e over the supply of bank deposits as well as currency in circulation in this case the government determines both the inflation rate and the nominal rate of interest on deposits provided currency and deposits are not perfect substitutes a positive nominal deposit rate is warranted illustrative estimates for turkey show that the revenue maximising deposit rate there would be 16 1 2 percent and the inflation rate 35 percentage points above the deposit rate i e 51 1 2 percent

seigniorage and the case for national money in countries with high rates of inflation there is typically movement away from the use of the local currency the paper analyzes the costs and benefits of using a local currency with emphasis on the seigniorage foregone by using a foreign money even if it should be desirable for a country to fix its exchange rate it still loses seigniorage if it does not use its own money the case for using a foreign money then turns largely on the superior discipline imposed on domestic policymakers by removing their control over the money supply alternative methods of imposing discipline are discussed estimates of the amount of seigniorage raised by different governments are presented seigniorage amounts in some cases to about 10 percent of government revenue estimates are also presented of both the annual flow and one time stock costs of giving up use of domestic currencies and instead using the dollar the flow cost is typically about 1 percent of gnp and the stock cost is around 10 percent of gnp

inequality of opportunity inequality of income and economic growth abstract despite the firm consensus that income inequality is intrinsically undesirable its impact on economic growth is much disputed we posit that the relationship between income inequality and economic growth is conditioned by the level of equality of opportunity our testable hypothesis is simple in societies where opportunities are unequally distributed where the material circumstances of parents act as binding constraints on the opportunities available to their children income inequality exerts a greater drag on future growth in contrast in societies with a more equal distribution of opportunities an increase in income inequality can be more easily reversed and need not constrain investment opportunities and growth we identify equality of opportunity with intergenerational mobility that is the degree of the correlation between parents attainments income and education and childrens attainments we use several recently developed internationally comparable measures of intergenerational mobility including the world bank s comprehensive gdim database to confirm that the negative impact of income inequality on growth is higher the lower is intergenerational mobility our results suggest that omitting intergenerational mobility leads to misspecification shedding light on why the empirical literature on income inequality and growth has been so inconclusive

emerging stock markets portfolio capital flows and long term economie growth micro and macroeconomic perspectives abstract the paper examines two major components of financial liberalization stock market development and portfolio capital flows in the context of less developed countries the paper considers microeconomic and macroeconomic perspectives on their implications for long term development and economic growth it concentrates on 1 a the role of stock markets in financing corporate growth 2 b the implications of stock market volatility for resource allocation and productive efficiency and 3 c the interactions between the foreign exchange and stock markets in the context of economic shocks its policy recommendations are that ldcs should promote bank based systems influence the scale and composition of capital inflows and prevent a market for corporate control from emerging

the future of the income tax the federal income tax has been under attack by the economics profession for more than a decade the attack comes from two directions supply siders who believe that progressive income taxation impairs economic incentives and more traditional economists who would substitute a progressive expenditure tax for the income tax 2 at one time support for the expenditure tax was confined to a few members of our profession including such distinguished names as john stuart mill irving fisher nicholas kaldor and james meade today it is fair to say that many if not most economists favor the expenditure tax or a flat rate income tax this group has joined the opponents of progressive taxation in the attack on the income tax despite an incessant barrage from both groups no country in the world is planning to abandon the income tax or is even considering a personal expenditure tax a wave of tax reform beginning with the u s reform in 1986 has been sweeping the world aimed at improving the income tax not at eliminating it tax preferences formerly regarded as sacrosanct are being removed and there is a distinct movement toward comprehensive income taxation 3 however individual income tax rates are being cut tax progressivity has been declining almost everywhere and reliance on the income tax has been diminishing it will come as no surprise to this audience that i approve of the base broadening feature of the current tax reform movement but i believe that the reduction in the redistributive effect of the income tax has gone too far in this paper i shall show that the progressivity of the u s tax system never very pronounced except during and immediately after the two world wars has been declining for more than two decades and that the tax reform act of 1986 reversed this decline but only slightly consequently we have a long way to go to improve the equity of the tax system i believe this can be done without punitive tax rates that will hurt economic incentives i begin with a brief review of recent changes in the u s distribution of income and follow this with an analysis of the effect of taxes on the income distribution i next examine arguments for and against the income tax with particular emphasis on its effects on economic incentives and its merits when compared with the expenditure tax i then evaluate the income tax as it emerged from the 1986 tax reform and conclude with tjoseph pechman passed away on august 19 1989 his presidential address was delivered at the onehundred second meeting of the american economic association december 29 1989 atlanta georgia joseph a pechman economic studies program the brookings institution 1775 massachusetts avenue nw washington dc 20036 i have benefited from the comments and suggestions on an earlier draft of this paper by henry j aaron richard goode jane g gravelle robert w hartman donald w kiefer herbert e klarman robert d reischauer clifford m winston and h peyton young but they should not be held responsible for the views expressed in this paper i am indebted to richard kasten for various simulations i am also grateful to stephen j kastenberg for research assistance and to diane a shugart valerie m owens and sara c hufham for secretarial assistance some of the more extreme supply siders argued that large tax cuts pay for themselves see for example laffer 1981 but i believe it is fair to say that this view has been totally discredited for a more reasonable supply side view see the economic report of the president 1982 2see for example michael j boskin 1978 david e bradford 1980 charles l ballard don fullerton john shoven and john whalley 1985 paul courant and edward gramlich 1982 martin feldstein 1978 robert hall and alvin rabushka 1985 john kay and mervyn king 1983 charles mclure 1987 mieszkowski 1980 and lawrence summers 1981 it is interesting that the recent popularity of the expenditure tax among economists was stimulated by a tax lawyer william d andrews 1974 3see pechman 1988

international overborrowing a decomposition of credit and currency risks summary the severity of the financial crises enveloping the tiger economies of southeast asia in 1997 came as a surprise to many observers this paper uses a simple fisherian model of the overborrowing syndrome to compare the asian crises of 1997 with earlier overborrowing episodes in mexico and chile while important similarities exist the crises in southeast asia have been exacerbated by the unhedged foreign exchange positions of asian banks these open currency positions not only imposed significant additional losses on the banks following devaluation they also magnified the scale of overborrowing during the cycle s initial boom phase failure to limit the exposure of banks to foreign exchange risk therefore increased the magnitude of the boom bust overborrowing cycle both ex ante and ex post the paper highlights the importance of effective regulation and supervision of capital markets with a focus on limiting the speculative currency positions of banks especially those that form the core of the domestic payments system and therefore enjoy a possibly implicit public guarantee improving the institutional infrastructure of financial supervision is the only effective way of mitigating the macroeconomic costs of overborrowing

korean inflation during the u s military administration of 1945 48 in korea the general state of impoverishment created income levels too low to collect sufficient tax revenues to support the government s spending goal thus the u s military administration was forced to rely on printing substantial quantities of money to finance its real expenditure gap thereby creating a high rate of inflation while fiscal pressure was similar there was significant difference in the magnitude of the inflation for example the monthly average inflation rate reached a peak of 11 percent in korea compared to a monthly peak of 322 percent in germany this comparatively moderate rate of inflation may have allowed the korean experience to go relatively unnoticed by academics yet it affords an opportunity to examine the dynamic process of inflation during a period with circumstances similar to those that produced the more frequently studied episodes of hyperinflation section ii of the paper briefly describes the post world war ii korean economy section iii will employ a structural vector autoregression svar to model the dynamic process of inflation and discusses the long run and contemporaneous restrictions employed to identify the structural parameters the data and subsequent econometric results are reported in section iv the results will indicate that the moderately high rate of inflation during the u s military administration can be largely explained by velocity shocks to money demand suggesting that a

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

the financial cycle and macroeconomics what have we learnt abstract it is high time we rediscovered the role of the financial cycle in macroeconomics in the environment that has prevailed for at least three decades now it is not possible to understand business fluctuations and the corresponding analytical and policy challenges without understanding the financial cycle this calls for a rethink of modelling strategies and for significant adjustments to macroeconomic policies this essay highlights the stylised empirical features of the financial cycle conjectures as to what it may take to model it satisfactorily and considers its policy implications in the discussion of policy the essay pays special attention to the bust phase which is less well explored and raises much more controversial issues

the output inflation trade off when prices are costly to change the output inflation trade off is investigated in a rational expectations equilibrium economy in which costly price setting makes it inefficient for agents to vary their prices at every instant it is shown that sticky prices are not some exogenous source of output fluctuation but result from the monetary policy process an economy with slow and counterinflationary money growth exhibits staggered changes in sticky prices as assumed in some new keynesian analyses an economy with fast money growth and a high degree of monetary accommodation exhibits either flexible prices or bunched frequently changing sticky prices

financial development and economic growth abstract this paper examines the empirical relationship between long run growth and financial development proxied by the ratio between bank credit to the private sector and gdp we find that this proxy is positively correlated with growth in a large cross country sample but its impact changes across countries and is negative in a panel data for latin america we argue that the latter findings is the result of financial liberalization in a poor regulatory environment our findings also show that the main channel of transmission from financial development to growth is the efficiency rather than the volume of investment

inflationary rigidities and orthodox stabilization policies lessons from latin america orthodox stabilization programs in latin american countries have been notoriously unsuccessful in combating inflation despite the imposition of stringent cuts in government deficits in most cases inflation came down only slowly and temporarily with concomitant declines in growth and employment the bolivian program one of the only latin american successes is contrasted with those of argentina brazil chile and mexico the problems of dealing with chronic inflation are compared with those of hyperinflationary countries and the influence of price and wage rigidities expectations and credibility is explored the study shows that fiscal restraint is a necessary but not sufficient condition for success and that sound management of nominal variables the exchange rate and money supply are also necessary the critical role of credibility is linked with price and wage rigidities in the chronic inflation countries whereas the unsuitability of hyperinflation is seen to increase the credibility of and thus the potential for successful stabilization programs

tax reform 1986 and marginal welfare changes for labor during the 1980s in the united states before tax income shifted away from the poor and toward the upper income groups changing the distribution of tax burdens or after tax income is one way to redress a growing imbalance in before tax income pechman 14 feldstein 6 and wallace et al 17 have all shown that the tax reform act of 1986 tra86 increased the progressivity of the combined personal and corporate income taxes an achievement not accomplished in the last two decades of income tax reform 14 tax reform can also increase or decrease the welfare of individuals in an economy through its effect on the allocation of labor supply resources tra86 reduced the highest marginal income tax rates from 50 percent to 28 percent for high income persons and removed some lower income persons from the tax roles such large marginal tax rate changes introduce significant potential for increased economic efficiency in labor supply and for welfare gains for the rich and poor alike these changes should be part of the benefit analysis of tax reform indeed hausman and poterba 10 report welfare cost changes that result from tra86 for the average male and female their estimates however do not account for welfare cost changes throughout the income distribution in addition to our use of microdata to estimate the marginal welfare cost of tax reform we use more precise measures of marginal tax rates than other researchers in this paper we use browning s partial equilibrium framework to examine the influence of the reduction in marginal tax rates from tra86 on the distribution of welfare gains from labor supply reallocation for males by population decile and for females by population decile and by marital status the empirical results illustrate how the tax reform affected low income female household heads where poverty is so heavily concentrated as well as other household heads and spouses the results indicate that tra86 reduced welfare costs in the economy but these welfare

economic stabilization conditionality and political stability imf conditionality is seldom so important that it dominates all other considerations for political stability imf stabilization programs often shift benefits from one group to another they expose elites to charges of selling the sovereignty of their countries the imposition of imf conditions particularly subsidy cuts may lead to sharp outbreaks of civil disorder nonetheless the imf provides resources that make adjustment easier and thus may lessen the chances of political instability for a country imf programs are seldom implemented fully as negotiated and the penalties for partial compliance are not great debtor countries have more flexibility in imposing austerity measures and the economic constraints are less binding than often assumed the very availability of alternatives to imf programs results in internal divisions because some favor debt repudiation and others oppose it groups now contend over solutions to the debt problems of their countries

interest rates and investment in east asia an empirical evaluation of various financial liberalisation hypotheses the article attempts to shed light on the appropriate interest rate policy in the process of economic development to this end we examine whether higher interest rates lead to higher investment and growth in four east asian countries we find that the investment rate went up with real interest rates up to 9 per cent in all four countries but started declining at still higher interest rates in two of the countries further a banking crisis occurred in each of the three countries for which the real interest rates exceeded 9 per cent this evidence rejects the neo structuralist argument nor does it support unbridled financial liberalisation yet it provides only limited support to stiglitz s case for mild financial repression real interest rates near zero since reducing real interest rates from say 6 to 3 or 0 per cent would have reduced investment the optimum policy seems to be closest to mckinnon s restrained financial liberalisation policy that is liberalisation with a moderate upper lim

the role of money supply shocks in the short run demand for money abstract previous money demand models are either inconsistent with contemporaneous adjustment of the price level to expected changes in the nominal money supply or imply implausible interest rate fluctuations in response to innovations in nominal money we propose a shock absorber money demand model in which money supply shocks affect the synchronization of asset transactions and so engender a temporary increase or decrease in desired money holdings expected changes do not engender such fluctuations in real money inventories in simultaneous estimates for eight industrial countries the shock absorber model proved empirically superior

the impact of government deficits on money growth in developing countries abstract this paper investigates the relationship between government budget deficits and money growth in the developing countries for which reliabile data exist it is sometimes suggested that it is more likely that money growth follows debt growth in developing countries due to the embryonic state of capital markets and because the central bank generally comes under direct control of the minister of finance our results provide only mixed support for this contention however in the majority of countries in our sample there is no evidence that government deficits affect money growth for high inflation years there seems to be more support for a relationship between deficits and money growth

capital inflow surges in emerging economies how worried should latin america and the caribbean be in the years leading up to the global economic crisis latin america and the caribbean received large capital inflows nonetheless the region survived the albeit short lived dramatic events of 2007 09 reasonably well with no financial crisis in any of the larger economies after the crisis capital inflows rose again in 2010 gross inflows to seven latin american countries argentina brazil chile colombia mexico peru and venezuela amounted to more than 6 percent of gross domestic product gdp and net inflows exceeded 3 percent of gdp more recently following the may 2013 speech of then chairman of the u s federal reserve ben bernanke there has been concern regarding the potential effects of tapering asset purchases by the u s federal reserve system and rising interest rates possibly spelling the end of large capital inflows to the latin american and caribbean region the literature on capital inflows suggests that while these flows represent an opportunity to spur investment and growth they may also increase vulnerability to financial crises macroeconomic instability and ultimately recession a relevant question then is whether the region can declare victory in being able to manage large capital inflows successfully or whether risks remain that justify strong measures our starting point is that the region has enjoyed strong surges in capital inflows we therefore decided to condition the analysis on surges occurring we do not seek to explain the reasons for such a surge one justification for this decision is that capital flows appear to be driven as much if not more by push rather than pull factors more specifically we seek to understand what determines whether such surges end in either a banking crisis or a recession while there is a substantial literature on the determinants of capital inflows their potential impacts have received much less attention the contribution of this paper is to analyze when inflow surges may end in severe economic problems including financial or macroeconomic instability rather than to identify the determinants of those surges we must first tackle the question of how to define a capital inflow surge we are helped in this regard by a small but growing literature however the current definitions of inflow surges in the literature may be injudicious we propose a new definition which considers the total size of the inflow episode across countries we also employ a more traditional definition based on yearby year inflows relative to a country specific threshold we contrast relevant statistics on the identified episodes using these two definitions and compare our episodes with others found in the literature we also consider whether the analysis should be conducted using gross or net inflows we take the view that employing net flows may discard useful information and that gross flows are relevant where financial instability is a potential concern even if net flows are zero a domestic financial system may intermediate large gross inflows when domestic residents purchase assets abroad we choose to focus on gross inflows but we include gross outflows as a potential explanatory variable so as not to lose information 1the empirical analysis in this paper develops a set of parsimonious models that discriminate reasonably well between the different economic outcomes we then analyze the case of a typical country from the region with a recent capital inflow surge providing a set of simulations to illustrate the economic magnitude of our results we simulate the changes in the estimated probabilities of negative outcomes given changes in certain critical variables we suggest that depending on the country inflow characteristics different policy measures may then be justified however a caveat is that emerging economies in general and latin america and the caribbean in particular have been experimenting with new policy measures and we are not able to evaluate their potential effectiveness in this paper

the term structure of interest rates during a financial reform argentina 1977 81 abstract this paper studies the term structure of interest rates in argentina following the financial and monetary reforms of 1977 which mainly entailed the liberalization and deregulation of the financial system using first order conditions from the international capital asset pricing model we derived a set of term structure equations expressed in terms of returns data alone empirical implementation of these equations yielded results that are consistent with an important degree of time variation in term premiums

credibility and changes in policy regime this paper addresses the issue of credibility from an econometric perspective it develops a rational expectations model of inflation in which the dynamics are driven by the level of government spending and by the effect of past inflation rates on the value of real taxes government expenditure is modeled as an exogenous autoregressive process subject to discrete changes in regime the regimes are defined by whether the level of spending is or is not consistent with the rate of inflation targeted by the government as part of a stabilization program in making their money demand decision the agents need to construct probability inferences regarding the state of the expenditure process credibility is quantified by the agents inferred probability that the joint observation of inflation the nominal interest rate and government spending is generated by the reformed expenditure regime in an application to israel results indicate that the failed stabilization program of november 1984 was less than fully c

the financial repression liberalization debate taking stock looking for a synthesis financial repression and liberalization became the object of fierce debates between academics and policy makers since the early 1970s as of the late 1980s financial liberalization became also part of the structural adjustment programs sponsored by the international monetary fund and the world bank however the literature on financial repression and liberalization remains controversial on its theoretical conclusions and policy implications given its importance for both the theory and policy of economic development and growth this paper looks for a possible synthesis after reviewing the theoretical contributions and empirical studies under the headings of the mckinnon shaw and new structuralists models the survey concludes that a new synthesis might be found in the post keynesian attempt to take an institutional perspective within a globalised financial and economic environment

together or apart the relationship between currency and banking crises abstract the purpose of this study is to provide empirical evidence on the links between currency and banking crises panel data probit and bivariate probit models are estimated to a sample of 21 developed and developing countries having monthly observations between the years 1985 and 2010 the findings indicate that banking crises precede currency crises and vice versa currency crises also indirectly influence future banking crises probability through external shocks liberalized financial markets or highly leveraged banking sectors the study also finds evidence of contemporaneous correlation between the two crises the results not only confirm the theoretical links between banking and currency crises but also underline the importance of higher frequency data in analyzing the relationship between various financial crises

the assessment the twentieth century achievements failures lessons the past century saw unprecedented rises in life expectancy and living standards it also witnessed major structural changes the rise of big government and two globalizations yet the century s economic history was marred by policy and market failures resulting in a massive world wide depression frequent financial crises particularly in the developing world and several inflation spurts central planning set back development for one third of the world s population transition to the market economy was at best slow in some instances disastrous income distribution within countries changed little while productivity convergence between rich and poor economies was virtually absent policy making learnt some lessons from the 1930s experience particularly in the areas of macroeconomic management international cooperation and free trade dogmatic recipes however were often resorted to at home aided and abetted by the pretensions of the economics profession

currency crises are they all the same abstract the plethora of currency crises around the world has fueled many theories on the causes of speculative attacks the first generation models focus on fiscal problems while the second generation models emphasize countercyclical policies and self fulfilling crises in the 1990s models pinpoint to financial excesses with the crisis of argentina in 2001 models of sovereign default have become popular again while the theoretical literature has emphasized variety the empirical literature has supported the one size fits all models this paper contributes to the empirical literature by assessing whether the crises of the last 30 years are of different varieties

bubble weak and strong hyperinflation theory and empirical evidence the monthly continuous inflation rate that maximizes the inflation tax revenue varies widely from 18 3 to 143 according to semi elasticity estimates for the german hyperinflation made by several authors cagan 1956 barro 1970 frenkel 1977 sargent 1977 goodfriend 1982 burmeister and wall 1987 christiano 1987 casella 1989 taylor 1991 engsted 1993 imrohoroglu 1993 michael et al 1994 those estimates lead one to conclude that during hyperinflation the german government could have obtained more tax revenue with lower inflation rates

on the simultaneity problem in the aid and growth debate this paper shows that foreign aid has a significant positive average effect on real per capita gross domestic product gdp growth if and only if the quantitatively large negative reverse causal effect of per capita gdp growth on foreign aid is adjusted for in the growth regression instrumental variables estimates show that a 1 percentage point increase in gdp per capita growth decreased foreign aid by over 4 adjusting for this quantitatively large negative reverse causal effect of economic growth on foreign aid shows that a 1 increase in foreign aid increased real per capita gdp growth by around 0 1 percentage points

macroeconomic effects of a tax on bond interest rates the effect of taxes on interest earned upon capital accumulation and inflation is discussed within an overlapping generations model it is shown that an increase in such a tax is likely to reduce both the capital stock and the inflation rate the model is extended to include the case of a small open economy where the effect on the external debt is discussed some simulation results demonstrate the magnitude of the effects the model is used to discuss the macroeconomic effects of financial liberalization copyright 1991 by ohio state university press

government revenue from money creation with government and private money abstract for a stationary state we show that if the government is as efficient as a competitive banking industry in producing money then the substitution of private for government money does not alter the revenue from money creation or the present value maximizing holding cost of money if households and non banking firms hold both government and private money then maximum present value requires that the reserve ratio maximize the monetary base and that the base nominal interest elasticity equal minus one with perfect foresight zero money balances and zero revenue from money creation is the only time consistent revenue maximizing solution

hyperinflations their origins development and termination abstract this paper summarizes and critically surveys research on hyperinflation appraisal and review of the literature considers the origins development termination and the lessons to be learned from hyperinflations the historical evidence as well as the econometric evidence is analyzed it is concluded that while the lessons to be learned from such episodes perhaps have been overstated a number of useful implications may be derived from studying hyperinflations such as an understanding of the forces which link monetary and fiscal policies to inflation and policy makers role in influencing individuals expectations

bank firm relationships and contagious banking crises this paper argues that in an open economy a banking system with close bank firm relationships may be easily subject to contagious banking crises because it is difficult to distinguish between crony capitalism and good main bank relationships 1 show that if international investors cannot distinguish the bank type the distinction between crony capitalism and good main bank relationships becomes very fuzzy in particular the model can explain sequences of bank defaults within a country even if the insolvent banks are very few ex ante as well as sequences of banking crises among countries that are equally rated by international investors but indeed differ in the ex ante solvency of their banking system

monetary trends in the united states and the united kingdom a review from the perspective of new developments in monetary economics milton friedman and anna schwartz monetary trends reports a great many findings 53 are enumerated in the introduction but paramount is the stability of the demand for money in the us and britain over the past century the money stock controls money income this proposition more than anything else is the point of their painstaking investigation friedman and schwartz argue against what might neutrally be called the early post war view of the macroeconomic role of money velocity will move easily to reconcile any level of nominal income to any money stock the demand for money in this view is a will o the wisp as the authors put it monetary policy has little influence over real activity stabilization policy necessarily relies on fiscal instruments the volume is completely convincing in disposing of this idea today s reader is likely to be puzzled why so much space is devoted to a view that has no serious adherents among professional economists friedman and schwartz are generals fighting an earlier war a situation accentuated by the long lags in putting this volume into print though the opposing armies fighting for the early postwar view have withdrawn in total rout a new front has opened up and the quantity theory is fighting for its life once again worse yet the new armies are fighting under the banner of free market economics and are led by former colleagues and students of milton friedman the midwest once the stronghold of the quantity theory is now largely occupied by the enemy the new monetary economics views the quantity theory as nothing more than an artifact of government regulation an economy organized along free market principles could function without money at all fischer black 1970 it is true that the kinds of monetary regulations imposed by the american and british governments of the past century create a more or less stable relation between a certain class of assets called money and nominal spending eugene fama 1980 but different regulations would alter that relation even the real bills doctrine anathema to quantity theorists because it invites unlimited expansion of the money supply has advocates in the new school thomas sargent and neil wallace 1981 a monetary system where the government is unconcerned about the money stock has been advocated by a university of chicago economist while visiting the hoover institution john bilson 1981 restoring the intrinsic value of money not limiting its quantity has been found to be the key to successful disinflation by one member of this group sargent 1982 a critical summary titled a laissez faire approach to monetary stability written see p 1528 above for publication information

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

the buffer stock notion in monetary economics not the least of harry johnson s contributions to our discipline was the series of survey papers on aspects of monetary economics which he produced during the 1960s and 1970s it is no exaggeration to say that the way in which the literature of monetary economics is organised even now follows the design which johnson first set out in 1962 and built on in the subsequent decade nevertheless the subject has not stood still and one of the more interesting developments of the last few years has involved the introduction of what has been variously described as the disequilibrium money shock absorber or as i prefer to call it the buffer stock notion into monetary economics the development of this line of thought was getting underway before johnson s untimely death much of it indeed under the auspices of his own research programme at the lse even so this did not happen early enough for the relevant ideas to be put in their proper niche by johnson himself and the buffer stock approach is not yet fully integrated into the mainstream of monetary economics much of the relevant literature is empirical concerned with modelling particular aspects of the monetary experience of specific countries hence it is fragmented and contains few papers which attempt a coherent account of just what this approach is and how it relates to other approaches to monetary analysis although essays by goodhart 1982a b and judd and scadding 1982a contain important discussions of these issues to the best of my knowledge only jonson 1976a and knoester 1979a have devoted entire papers solely to this central issue and these are relatively inaccessible and hence less widely known than they deserve to be in this lecture i shall attempt to give a brief account of the essentials of this approach first i shall sketch out its microeconomic background and then i shall discuss those theoretical characteristics which differentiate it from the neo austrian analysis of robert e lucas jr and his associates as well as from the conventional keynesian approach to monetary economics last but by no means least i shall argue that it yields simple theoretical insights into important empirical and policy related issues which are troublesome for alternative approaches in short my tribute to harry

financial opening and development evidence and policy controversies this paper outlines possible channels linking commercial and financial openness this inquiry is motivated by a salient feature of the global economy in recent decades the embrace by developing countries of financial reforms the adjustment process to the growing financial integration has been rocky frequently associated with financial crises these developments have led to a spirited debate concerning the wisdom of unrestricted capital mobility between oecd and emerging market countries various studies have identified circumstances in which unlimited capital mobility may be suboptimal this paper argues that notwithstanding the above debate the strongest argument for financial opening may be the pragmatic one like it or not greater trade integration erodes the effectiveness of restrictions on capital mobility hence for successful emerging markets that engage in trade integration financial opening is not a question of if but of when and how some insight into the possible linkages between financial and trade opening is obtained by looking at the patterns of changes in openness in the last 30 years in order to evaluate the statistical significance of the association between financial and trade openness i apply a panelregression methodology the units of observations are nonoverlapping five year changes in the openness measures throughout 1969 1998 for all countries subject to data availability table 1 presents the regressions where the dependent variable is the change in financial openness the explanatory variables are changes in trade openness and changes in the level of gdp per capita allowing for country fixed effects regression i reports all developing countries subject to data availability regression ii excludes from the sample developing economies countries that are characterized by financial openness that exceeds 100 percent or by trade openness that exceeds 60 percent and small island economies finally regression iii deals only with the oecd countries the first two regressions indicate a highly significant positive association between changes in financial and commercial openness in developing countries this effect in the oecd countries is positive but at a substantially lower significance level in aizenman and ilan noy 2003 annual data are used to investigate the impact of political economy and other structural variables on the links between trade and financial openness an extended version of our model where political economy considerations determine the efficiency of the tax system suggests that democracies are associated with lower financial openness our empirical investigation 317 social sciences 1 department of economics university of california santa cruz 1156 high st santa cruz ca 95064 and nber e mail jaizen ucsc edu i thank shang jin wei for sharing the data on financial openness and ilan noy and bill koch for excellent research assistance useful comments by mike dooley michael hutchison phil mccalman graciela kaminsky and ken kletzer are gratefully acknowledged 1 a useful survey of financial liberalization is john williamson and molly mahar 1998 see carlos diaz alejandro 1985 dani rodrik 1999 and thomas hellmann et al 2000 for skeptical assessments of the gains from financial liberalization for studies dealing with the financial instability associated with capital account opening see the papers in sebastian edwards and jeffrey frankel 2002 on the association between financial integration and financial crises see asli demirguc kunt and enrica detragiache 1998 guillermo calvo 1998 and graciela kaminsky and carmen reinhart 1999 2 financial openness measures gross private capital inflows gross private outflows 100 gdp using the data documented and applied by shang jin wei and yi wu 2002 and eswar prasad et al 2003 trade openness measures exports imports 100 gdp using the world development indicators wdi data 3 the inclusion of gdp per capita as an explanatory variable is suggested by the linkages between gdp per capital level and financial depth 4 following the approach of alex cukierman et al 1992 one expects less polarized societies and better functioning democracies to be characterized by more efficient taxcollection systems applying this conjecture a more efficient tax system would be associated also with lower tax

does the ecb act as a lender of last resort during the subprime lending crisis evidence from monetary policy reaction models abstract we investigate whether the ecb aligns its monetary policy with financial crisis risk in emu member countries we find that since the outbreak of the subprime crisis the ecb has significantly increased net lending and reduced interest rates when banking and sovereign debt crisis risk in vulnerable emu countries greece ireland italy portugal and spain increases while no significant effect is identified for the pre crisis period and relatively tranquil emu countries austria belgium france germany and the netherlands these findings suggest that the ecb acts as a lender of last resort for vulnerable emu countries

fiscal inconsistencies and high inflation abstract this paper presents a simple model of steady state inflationary financing the discrepancy between the target level of spending and a fixed taxing capacity indicates the degree of fiscal pressures this variable need not be monotonically related to the measured deficit since actual expenditures are endogenous large fiscal inconsistencies generate unique steady states located on the bad side of the inflation tax laffer curve there high inflation may coexist with low observed deficits and the revenue constraint results in repressed spending such situations correspond qualitatively with the loss of control over fiscal policies typical of high inflation economies

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

functional form of the demand for real balances in cagan s hyperinflation model this paper uses recent advances in the development of testable implications of the cagan model of hyperinflation it extends the range of candidate functional forms of the demand for real balances in hyperinflations to include nonstandard versions in which the absolute inflation elasticity is a decreasing function of inflation these nonstandard functional forms are of interest because they are known to have desirable theoretical properties this paper finds empirical justification for a nonstandard form that performs at least as well as the traditional semilogarithmic functional form
