theory of tax smoothing in the small open economy abstract we derive necessary and sufficient conditions for the martingale like behavior of tax rates the world real interest rate is exogenous to the small domestic economy consumers are risk averse and markets are incomplete the government s loss function is not ad hoc

optimal capital income taxation with incomplete markets borrowing constraints and constant discounting for a wide class of infinitely lived agent models chamley has shown that the optimal capital income tax rate is zero in the long run lucas has argued that for the u s economy there is a significant welfare gain from switching to this policy this paper shows that for the bewley class of models with incomplete insurance markets and borrowing constraints the optimal tax rate on capital income is positive even in the long run therefore cutting the capital income tax to zero may well lead to welfare losses

currency substitution financial innovations and money demand a note this note presents some finnish evidence on the importance of currency substitution and financial innovations for money demand it is also shown that conventional demend for money specifications which do not take these factors into account are clearly misspecified and produced unreasonable results the problem is particularly acute for narrow concepts of money

joint implications of consumption and tax smoothing in this paper the joint hypotheses of consumption and tax smoothing are shown to imply that the present value of expected proportionate declines in government non interest outlays is approximately equal to a log linear function of the budget deficit and private dissaving in this exact linear relation the budget deficit signals declines in future government outlays after controlling for prospective changes in the tax base private dissaving controls for such prospective changes since under the joint hypotheses the present value of expected proportionate rises in tax revenues are approximately equal to a log linear function of private dissaving both exact linear relations are tested in a var framework on annual post world war ii u s data we find considerable empirical support for the theory

inflation hedging and the demand for money some empirical evidence this paper explores the role of nominal rate of return uncertainty and inflation hedging as potentially important factors explaining the pattern of money demand using u s quarterly data over the period 1952 2 1982 4 it is shown that in conformity with theoretical considerations the nominal rate of return uncertainty variable tends to have a significantly positive effect and the inflation hedging variable the covariance between nominal rate of return and inflation rate a significantly negative effect on the demand for money these findings seem to be reasonably robust in terms of various definitions of income interest rates inflation rate and money variables as well as in terms of different estimation methods

estimating the size of the danish shadow economy using the currency demand approach an attempt the currency demand approach provides some insight into the size and development of the shadow economy in denmark currency demand is statistically affected by tax rates the difference in currency demand is calculated by comparing the actual tax burden over time to the lowest tax burden in the period 1952 82 the shadow economy grew steadily to 10 per cent of gnp in 1977 and then fluctuated between 7 10 per cent of gnp for the period 1978 82 the calculated size fits nicely with the results obtained using the same

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

analysis of trends in technical and allocative efficiency an application to texas public school districts abstract we present a new dea based method to analyze efficiency trends over time and differences across subgroups in a panel data setting we employ a result that the aggregate technical and allocative inefficiency score equals the technical inefficiency when input quantities are aggregated into a single total input cost variable and develop test procedures to evaluate the presence of allocative inefficiency we apply these methods to test for the presence of allocative inefficiency in texas school districts over 1993 99 and analyze shifts and trends in both technical and allocative inefficiencies over time for different regions our empirical results indicate the existence of statistically significant allocative inefficiencies while technical inefficiency increased over the six year sample period allocative inefficiency remained relatively stable during this period these results for the full sample obtain also when we repeat the analysis for different regions

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

welfare analysis of currency regimes with defaultable debts abstract we modify the cole and kehoe model by including domestic debt according to the original model a speculative attack on a high debt level issued abroad triggers external debt default here it is possible to inflate away the domestic debt to avoid the external debt default we consider two possibilities for domestic debt denomination i local currency and ii common currency in the second case inflation depends on a monetary union decision our numerical results show that to have a debt share denominated in a common currency is optimal when the refinancing risks are highly correlated across union members otherwise the best is to keep the domestic debt denominated in local currency finally the extreme case of having all debt issued abroad and denominated in a foreign currency is suitable when under alternative regimes suboptimal inflation motivated by political factors is likely although the paper was originally developed for emerging market economies it sheds some light on the recent eurozone crisis

currency substitution and instability in the world dollar standard comment myron ross correctly points out in his comment that u s price inflation is better predicted by the american money supply mlus than by the broader ten country world money supply mlw over the whole statistical time series from 1960 to 1980 provided in mckinnon s 1982 article specifically he showed that american price inflation is more highly correlated with mlus lagged one or two years than with mlw similarly lagged however mckinnon s present tense assertion that in general growth in the world money supply is a better predictor of american price inflation than is american money growth applies only to the weak dollar standard of the 1970 s and early 1980 s as his preceding discussion intended but failed to indicate clearly only in this later period of volatile exchange rates and price level instability in the united states do alternative hard currencies such as the yen and deutsche mark become competitive as international stores of value and units of account hence international currency substitution associated with the ebb and flow of speculation against or for the dollar significantly destabilized the demand for mlus in the 1970 s and 1980 s and only in this later period might one expect the sum of these internationally substitutable monies ml to predict world and perhaps even american price inflation better than does mlus in contrast during the strong dollar standard of the 1950 s and 1960 s the dollar was unchallenged as international money exchange rates were by and large convincingly fixed speculation for or against the dollar was incapable of substantially altering u s interest rates or of directly affecting the demand for mlus because cyclical international influences did not then destabilize the demand for dollars mlus was by itself a fairly efficient predictor of american prices thus ross s statistical results for the period 1960 to 1980 show somewhat greater predictive strength in mlus compared to ml because the 1960 s data outweigh the dissimilar data of the 1970 s let us instead partition the sample of imf data around the year 1970 whence began the transition from fixed to fluctuating exchange rates and the maturation of alternative monetary systems in europe and japan after applying similar statistical correlation procedures to those used by ross we show a striking structural shift in the world s monetary system the explanatory power of mlw increases sharply as that of mlus declines moderately tan 1982 for the early period of 1960 to 1970 table 1 shows simple correlation coefficients between annual percentage changes in money supplies and changes in american and world wholesale price indices the mlus provides a good explanation of u s prices and of world prices one to two years hence whereas the broader definition of mlw in which mlus enters with a 50 percent weight does surprisingly poorly being insignificantly correlated with american or world prices apparently money growth in industrial countries other than the united states was not then an independent source of worldwide inflationary pressure during the strong dollar standard table 2 shows the same simple correlations between percentage changes in prices and money for the weak dollar standard of stanford university please note that a typographical error giving the last word in the original title as market appeared on the cover of the june 1982 issue of this review the title was correct in the table of contents and on the article

the cost of public schooling in new york state the role of scale and efficiency in 1978 79 cost differentials between large and small school districts are decomposed into scale and efficiency effects the analysis shows that scale economies enjoyed by large districts can come at the expense of the efficient production of educational outcomes attention is focused on the possible loss of efficiency associated with efforts to increase size by closing schools and consolidating school districts empirical evidence from new york state is presented which shows that lower levels of efficiency exist in large compared to small school districts implications for policy are explored

fiscal discipline and the budget process the critical economic policy issue for many oecd countries developing countries and transition economies currently is fiscal consolidation and the maintenance of long run fiscal balance two related components underlie this general goal first several countries face the issue of deficit reduction particularly those countries with high debt gdp ratios second it is becoming increasingly apparent that major reforms of the welfare system and specifically of social security systems are critical ingredients of a long lasting fiscal consolidation see alesina and perotti 1995a in the case of monetary policy a constructive discussion has generated a widespread consensus about the benefits of different monetary institutions relatively few economists dispute the benefits of a certain amount of central bank independence even though different commentators and policymakers may disagree on the optimal degree of independence also a contracting approach has highlighted the benefit of inflation targeting and of certain institutional relationships contracts between the executive and the central bank a similar theoretical and empirical discussion on the role of budget procedures and budget institutions is just beginning in this paper we ask the following two questions i do budget procedures matter for the determination of the budget balance and its composition ii are there certain institutional reforms that one should feel comfortable in recommending based on the relatively scarce empirical evidence available we tentatively answer yes to the first question budget procedures matter on the second question we suggest that the two critical areas of reform are first more transparency second a strengthening of the roles of the executive branch vis a vis the legislature and of the treasury minister vis a vis the rest of the executive branch in order to achieve a centralized and top bottom approach to the budget process

currency substitution capital mobility and money demand abstract this paper re examines the currency substitution cs issue by specifying a general portfolio balance pb model where domestic residents demand for foreign money is distinguished from their demands for foreign non monetary assets the latter possibility which reflects international capital mobility as opposed to cs per se is already a key feature in the open economy macro literature the inclusion of foreign money leaves the usual asset demand functions unchanged in the pb model that ignores cs at least as far as the appropriate rate of return arguments and their signs are concerned although this suggests that cs is of limited importance in macro modelling it implication for the estimation of money demand functions is pursued an initial attempt is made to empirically isolate the separate efects of high capital mobility and currency substitution for canada germany the united kingdom and the united states the results while not conclusive due to high multicollinearity problems bring into question the empirical as well as the theoretical relevance of currency substitution

model uncertainty and intertemporal tax smoothing in this paper we examine how model uncertainty due to the preference for robustness rb aects optimal taxation and the evolution of debt in the barro tax smoothing model 1979 we rst study how the government spending shocks are absorbed in the short run by varying taxes or through debt under rb furthermore we show that introducing rb improves the model s predictions by generating i the observed relative volatility of the changes in tax rates to government spending ii the observed comovement between government decits and spending and iii more consistent behavior of government budget decits in the us economy finally we show that rb can also improve the model s predictions in the presence of multiple shocks

the production characteristics of local public education a multiple product and input analysis since the seminal work of baumol panzer and willig 1 economists have become increasingly interested in incorporating the multifaceted nature of real world production functions into their empirical analyses multiproducts multiple inputs and the relaxation of the long run equilibrium condition are some prime examples of major innovations in production modeling an excellent example of this innovative literature is the study by cowing and holtmann 7 that focuses on the short run production characteristics associated with the hospital services industry specifically cowing and holtmann find evidence contrary to long run equilibrium and that economies of scope are at least as important as economies of scale in the production of hospital services moreover several empirical studies relating to the production characteristics of other goods and services such as higher education 6 crime prevention 9 electric utilities 15 and airlines 5 have provided ample evidence that these pertinent factors matter from both an econometric and a policy perspective the literature concerning the production characteristics of primary and secondary education however has lagged behind in terms of incorporating more realism into the analysis typically studies concerned with primary and secondary education production 2 3 13 14 maintain that schools operate at a long run equilibrium position and produce a single output with a single input i e teachers thus assuming away factors which these other industry studies have found to be significant in fact jimenez 12 is the only study to date on local primary and secondary education production that is based on less restrictive assumptions several limitations are associated with his research however each of these limitations reduce the generality of his findings concerning the production characteristics of primary and secondary education first jimenez employs a small sample to obtain estimates of various production characteristics bringing into question the overall

income fluctuation and asymmetric information an example of a repeated principal agent problem we examine a simple repeated principal agent model with discounting there are a risk averse borrower with an unobservable random income and a risk neutral lender the efficient contract is characterized it tends to the first best constant consumption contract as the discount factor tends to one and the time horizon extends to infinity if the time horizon is infinite and the contract is legally enforceable the borrower s utility becomes arbitrarily negative with probability one if the borrower has constant absolute risk aversion consumption is transferred between any two states at a constant interest rate which is less than the rate of time preference

lessons on monetary policy from the 1980s t he half decade running from mid 1982 to mid 1987 was a pretty good era for u s monetary policy as these things go a sharp easing of policy beginning some time around midyear 1982 helped set in motion a recovery from the most severe business downturn the united states had experienced since the 1930s a downturn that tight monetary policy earlier on had deliberately brought about in order to slow the alarming acceleration of prices the recovery that ensued developed into a sustained expansion that continued without interruption through the end of 1987 thereby setting a new record for the longest recorded business expansion in u s peacetime experience a fiscal policy based on unprecedentedly large and continually growing structural budget deficits was a major factor underlying this record length expansion but at least monetary policy did not stand in the way just as importantly the severe 1981 82 recession served its intended purpose of substantially restoring price stability and even after five years of expansion inflation remained modest by recent historical standards at least as judged by these outcomes for the standard objectives of macroeconomic policy u s monetary policy was a distinct success during these years economists hoping to say something useful about monetary policy have had a tougher time the quantitative relationships connecting income and price movements to the growth of familiar monetary aggregates including especially the m1 measure of the money stock that had been the chief focus of monetary policy during 1979 82 utterly fell apart during this period moreover the collapse of these long standing

international lending with moral hazard and risk of repudiation in this paper i examine the constrained optimal pattern of capital flows between a lender and a borrower in an environment in which there are two impediments to forming contracts the first impediment to contracting arises from the assumption that lenders cannot observe whether borrowers invest or consume borrowed funds this assumption leads to a moral hazard problem in investment the second impediment arises from the assumption that the borrower as a sovereign nation may choose to repudiate his debts the optimal contract is shown to specify that the borrowing country experience a capital outflow when the worst realizations of national output occur this seemingly perverse capital outflow forms a necessary part of the optimal solution to the moral hazard problem in investment

tax evasion and the demand for currency in norway and sweden is there a hidden relationship variables associated with the level of hidden economic activity are examined in terms of their effects on the demand for currency in norway and sweden aggregate time series of marginal tax rates are compiled for this purpose no such effects are evident for norway while in the case of sweden the demand for currency was found to be significantly related to marginal tax rates these estimates are then used as a basis for deriving an estimate of the size of the hidden economy in sweden an analysis of the assumptions underlying this procedure shows that the uncertainty involved in applying the currency approach to measuring the size of the hidden economy is so great as to make it hazardous to rely on such estimates
