boundary optima and the theory of public goods supply a comment abstract campbell and truchon provide a new generalized samuelson condition that takes care of all interior and boundary pareto optimal allocations they observe that interior optima may be limit cases in the set of all pareto optima this comment shows that by using kolm s triangle the phenomenon observed in public good economies is not special but can be found in private good economies too

generalized samuelson conditions and welfare theorems for nonsmooth economies abstract we give intuitive samuelson conditions for a very general class of economies smoothness and monotonicity are not required we provide necessary and sufficient conditions for all pareto efficient allocations including those on the boundary we prove that if all agents have a cheaper point the supporting prices fully decentralize the allocation we also show first and second welfare theorems as corollaries to the characterization of efficient allocations

a confirmatory analysis of the unit root hypothesis for oecd consumption income ratios this article investigates the existence of a unit root in the consumption income ratio for a sample of 23 oecd countries over the period 1960 to 2005 for that purpose we first use recently developed unit root tests with good size and power second we employ the more powerful panel unit root tests of pesaran 2003 and smith et al 2004 that take the null of nonstationarity and a bootstrap version of the test of hadri 2000 that takes stationarity as the null hypothesis overall our confirmatory analysis renders clear cut evidence that oecd consumption income ratios contain a unit root

the demand for money in developing countries assessing the role of financial innovation traditional specifications of money demand have commonly been plagued by persistent overprediction implausible parameter estimates and highly autocorrelated errors the authors argue that some of these problems stem from the failure to account for the impact of financial innovation they estimate money demand for ten developing countries using various proxies for financial innovations they also assess the relative importance of this variable finding financial innovation can be better modeled as a stochastic random walk trend rather than a deterministic time trend financial innovation plays an important role in determining fluctuations of the demand for money the importance of this role increases with the rate of inflation

a multicountry characterization of the nonstationarity of aggregate output the authors compute the scaled varlogram the variances of kth differences scaled by the variance of first differences of the log of annual per capita real aggregate output gdp or gnp as measured by 1 the long series for the united states and united kingdom 2 angus maddison s 1982 long series for twelve countries and 3 the postwar ifs data for thirty two countries simulations show that the scaled varlogram of real output is nearly always more consistent with the data being generated by parsimonious difference stationary than trend stationary univariate processes in fact the data reveal some excess nonstationarity relative to parsimonious arima models the power of the scaled varlogram to discriminate between trend stationary and difference stationary processes is somewhat greater than that of a dickey fuller type f test copyright 1990 by ohio state university press

an extension of the second welfare theorem to economies with nonconvexities and public goods in this paper we report a generalization of the results of foley and guesnerie on the second welfare theorem to economies with arbitrary nonconvex production sets the nature of marginal cost prices in such economies is clarified through the use of the clarke tangent cones

investment and the nominal interest rate the variable velocity case investment and the nominal interest rate the variable velocity case evan f koenig models treating money either as a consumer good or as a producer good are encompassed by a model in which both households and firms use money as a buffer between receipts and expenditures a rise in nominal interest rates increases resources devoted to intermediation while discouraging purchases financed from accumulated cash if investment is financed from contemporaneous earnings there is a tendency to substitute out of consumption and into investment when interest rates are high greater resources devoted to intermediation generate a negative wealth effect the net impact on investment is ambiguous i introduction the relationship between investment and the nominal interest rate in an economy where the cash balances of households and firms are rigidly linked to their respective expenditures has been examined by koenig 1987b in such an economy the nominal interest rate acts like a tax on agents purchases as a result households are inclined to save rather than spend when the nominal interest rate is relatively high provided that at the margin firms are able to finance at least some of their capital spending out of contemporaneous earnings this increase in desired saving is only partially offset by a decrease in desired investment realized investment is thus greatest when the nominal interest rate is high in comparison to its own moving average a short run tobin effect this paper extends koenig s analysis to the case in which households and firms at a cost in terms of real resources are able to increase the velocity of money in this context it is shown that the short run tobin effect may be reversed intuitively when the nominal interest rate is high consumption of financial services by households and firms may rise to such an extent that any decline in the consumption of nonfinancial goods and services is overwhelmed reducing the resources available for investment as in the earlier paper i allow for the possibility that some fraction 1 u of firms investment expenditures can be financed from contemporaneous earnings unless u equals zero there is a stockman effect 1981 a tendency for investment to be depressed whenever the nominal interest rate is expected to be higher on average in the future than it has been in the past when u equals unity so all investment must be financed out of accumulated assets the money balances of the representative firm can be interpreted as an argument of its production function regardless of the value of u the money balances of households may be thought of as an argument along with gross household spending of an indirect utility function thus both of the most frequently used methods of modeling the role of money as an argument of the household utility function and as an argument of the production function are special cases of the model developed here this is a substantially less restrictive framework than that employed by fischer 1979 sweeney 1984 cohen 1985 and obstfeld 1985 each of whom has also examined the effects of anticipated policy in an economy where the velocity of money is variable 1 section ii discusses the utility and profit maximization problems facing households and firms respectively and shows how the behavior of economic agents is affected by the presence of real costs of financial management a dynamic analysis is undertaken in section iii and it is shown that the short run tobin effect may operate in reverse a summary concludes the paper throughout agents are assumed to possess perfect foresight ii the model preliminary analysis intuition imagine a world in which each household receives wage and dividend income at discrete intervals but desires to purchase and consume output continuously through time

robust nonnested testing and the demand for money nonnested hypothesis testing procedures recently have been extended to dynamic nonnested models we propose robust tests that generalize the j test and the f test for nonnested dynamic models with unknown serial correlation and conditional heteroscedasticity in errors and regressors we investigate the finite sample properties of our test statistics and propose to use bootstrap methods or the fixed b asymptotics developed by kiefer and vogelsang to improve the asymptotic approximation to the sampling distribution of the test statistics we compare the semiparametric bootstrap and the fixed b approaches with the standard normal or chi squared approximations using monte carlo simulations and find that they give markedly superior approximations we also present an application to u s money demand models where consumption seems to be a better variable than income as a scale variable in the money demand function

financial technology shocks and the case of the missing m2 m2 growth was unusually weak in the early 1990s when its velocity soared although m2 growth subsequently recovered its velocity plateaued at a high level giving rise to a case of missing money these swings in m2 growth have accompanied opposite swings in bond mutual fund inflows m2 growth is better tracked and the missing m2 problem is resolved when money models are modified to account for shifts in bond mutual fund costs this approach avoids the capital gains and portfolio substitution problems posed by adding bond or equity funds to m2 while capturing the substitution effects relevant to money demand

the holmes smyth effect some preliminary exercises with the uk demand for narrow money the primary purpose of this paper is to test a plausible data coherent representation of the consumption based model of the demand for money against and analogus representation of the standard income based formulation on the basis of non nested tests neither model canbe maintained consequently the possibility of tax cuts being contractionary the holmes smyth effect is still an open question

multiple and pairwise non nested tests of the influence of taxes on money demand the minimal computational requirements of the linear embedding techniques initiated by davidson and mackinnon 1981 accommodate multiple and binary tests of autoregressive non nested regression models with different dependent variables the small sample adjustments of fisher and mcaleer 1981 effectively reduce the size of the p tests for our models our application to transactions demand for money models supports the holmes and smyth 1972 hypothesis that pre tax variables are preferred to gnp in m1 money equations

unfunded liabilities and uncertain fiscal financing we develop a rational expectations framework to study the consequences of alternative means to resolve the unfunded liabilities problem the projected exponential growth in federal social security medicare and medicaid spending with no known plan for financing the transfers resolution requires specifying a probability distribution for how and when monetary and fiscal policies will change as the economy evolves through the 21st century beliefs based on that distribution determine the existence of and the nature of equilibrium we consider policies that in expectation combine reaching a fiscal limit some distorting taxation modest inflation and some reneging on the government s promised transfers in the equilibrium inflation targeting monetary policy and debt targeting tax policy cannot anchor expectations on those target variables expectational effects are always present but need not have large impacts on inflation and interest rates in the short and medium runs in the economy s stationary distribution the capital stock may grow or shrink and substantial probability falls on little or no reneging

interpreting econometric evidence the behaviour of consumers expenditure in the uk abstract the dynamic models of consumers expenditure proposed by davidson et al 1978 and hendry and von ungern sternberg 1979 are re appraised in the light of hall s 1978 analysis of the empirical implications of the life cycle permanent income hypothesis in particular that the series for consumption should obey a random walk apart from trend in an attempt to reconcile the conflicting findings monte carlo experiments are used to demonstrate that if the davidson et al model were actually correct the hall model would appear to give a good description of the data and would probably not be rejected all the models are re estimated with new data for the uk and these data do reject a modified random walk specification in conclusion we discuss the issue of income exogeneity and comment on questions of model selection and interpretation

the output effect of a transition to price stability when velocity is time varying this paper explores the effect of time varying velocity on output responses to policies for reducing stopping inflation we study a dynamic general equilibrium model with sticky prices in which we introduce time varying velocity specifically we endogenize time varying velocity into the model developed by ireland 1997 for analyzing optimal disinflation the nonlinear solution method reveals that depending on velocity the disinflationary boom found by ball 1994 may disappear even under perfect credibility and that early output losses may be much larger than previously thought indeed we find that a gradual disinflation from a low inflation may even be undesirable

disequilibrium buffer stocks and consumers expenditure on non durables the authors examine the importance of a disequilibrium real balance effect on non durable consumers expenditure in the u k using cointegration techniques and the johansen procedure they first establish a desired long run demand function for liquid assets depending on income wealth and a set of interest rates deviations of liquidity from this desired level cause changes in consumption via intertemporal substitution but via its effect on disequilibrium liquidity consumption is modeled in an error correction framework and is also found to depend on income and financial wealth both the disequilibrium liquidity and wealth terms may be picking up the effects of financial liberalization e g mortgage leak on consumption as funds released will be temporarily held in financial assets they also find some evidence that changes in the distribution of income have an independent effect on aggregate consumption copyright 1991 by mit press

a simulation study of the interactive effects of taxes and inflation on the relative price of land recent experience in the united states with high and variable inflation has led to an outpouring of research concerning inflation s impact on the relative prices of real and financial assets with the exception of three recent papers feldstein 1980a rose 1986a alston 1986 the impact of inflation on the relative price of land has been neglected land is usually eliminated from economic models of the tax system so that the effects of inflation s complex interaction with the income tax system on firm financing and valuation of capital can be highlighted in this paper we take the opposite approach the effects of inflation on corporate financing of capital are suppressed by allowing only bond financing in order to highlight the effects of inflation and tax rate changes on the relative price of land

why don t you trade only four days a year an empirical study into the abnormal returns of quarters first trading day in this research i examined a calendar anomaly that occurs at the beginning of each quarter through an examination of 34 years of daily and annual returns for the s p500 and 13 years of returns for popular etfs i have demonstrated the existence of the first day of quarter fdq effect by trading only four days a year from the beginning of 2000 until the end of 2013 an investor could have gained 113 1 of the s p500 returns for that period while being exposed to stock risk for only 56 days moreover for 11 of those 14 years of trading the fdq was responsible for more than 10 of the annual returns only for two years since 2000 2001 2005 has the fdq yielded a negative return the biggest beneficiary of the fdq is the financial sector which for the last 13 years of investing has been non fertile showing 6 12 total return investing only at the beginning of each quarter for a total of 52 days would have yielded a return of 40 17 the next beneficiary of the fdq is the technological sector the 82 5 of total return gained in this sector over the last 13 years could have been gained in only 52 days of trading

inflation and savings international evidence on inflation induced income losses the fall in the average propensity to consume a p c in the i970s in most industrialised countries has been the subject of much debate it has been ascribed to a wide variety of causes most important it has been widely interpreted as a typical example of a situation in which economic forecasting has failed simply because it did not take into account the psychological effects of rapid changes in the economic environment given the inability of economists to predict sudden changes in consumer expectations these would naturally set severe limits to the usefulness of economic forecasting this paper takes a different approach to the problem it contends that the true fall in the a p c has been considerably lower than indicated by the statistics the argument runs roughly as follows the increase in the rate of inflation has led to a net transfer of real resources away from the personal sector this transfer was due to the fall in the real value of net monetary assets held by the personal sector and issued by the public and business sectors of the economy consumers considered this fall as negative income and adjusted their expenditure accordingly the definition of personal sector disposable income used in the national accounts statistics does not include such a correction in inflationary periods this leads to a large overestimate of true personal sector disposable income given this overestimate of the denominator it is hardly surprising that measured c y should fall when the rate of inflation rises the simplicity of this theory indicates that it can quite easily be subjected to empirical testing the tests proposed in this paper are based on a novel specification of the consumption function developed by davidson et al i978 henceforth dhsy this function has a solid theoretical foundation good statistical properties and allows both shortand long run phenomena to be easily incorporated in an acceptable manner simple theoretical considerations indicate roughly how one should go about measuring true income this corrected measure of income can be incorporated into the consumption function to be estimated in such a way that the coefficient of the correction term is endogenously determined in the regression the statistical properties of the resulting regressions are the evidence leading to a rejection or tentative acceptance of the theory

generalized functional forms and demand for money in an open economy the case of the united kingdom the purpose of this paper are twofold first to apply a box cox model to the uk money demand relationship within an open economy framework in order to empirically investigate the proper functional form supported by the data in this general setting secondly to test for the porper scale variable in the uk money demand function within the open economy box cox specification these improvements enhance the accuracy of our measures of monetary and fiscal policy effects and our understanding of the interdependence between different economies the empirical results derived here reject the restrictive linear and log specifications in favour of the general box cox model under both income and consumption based money demand specifications the traditional income based model however escaps unharmed from the challenge put forward by mankiw and summers 1986

the role of monetary shocks and real shocks on the current account the terms of trade and the real exchange rate dynamics a svar analysis the article is an empirical investigation of the role of monetary shocks and real shocks on the current account the terms of trade and the real exchange rate dynamics three new open economy macro economics noem models are studied to motivate the empirical investigation then i apply the blanchard quah decomposition to identify a svar model the empirical evidence supports the noem model with the simplified household preference specification and with the small degree of pricing to market the evidence also illustrates monetary shocks important for the real exchange rate and the terms of trade movements but not for the current account fluctuations

fiscal policy and stabilization of exchange rates under alternative criteria this paper examines the role of fiscal policy in the determination of the exchange rate in a small open economy and discusses the efficiency of feedback rules in minimizing the volatility of the exchange rate two criteria are introduced to stabilize the large fluctuations in exchange rates i minimizing the variance of the exchange rate and ii minimizing the expected squared gap between the full and incomplete current information values of the exchange rate the two criteria are based on different beliefs regarding the working of the market forces and require the choice of diametrically opposed policy rules

has m2 demand in the usa become unstable evidence from an error correction model the purpose of this paper is to estimate an appropriate broad money demand function for the united states and to examine its stability after 1987 when the federal reserve system began using m2 as a policy guide special attention is paid to the model specification its dynamic structure and to its cointegration properties the results from various dynamic error correction models suggest that i the money demand relationship is stable ii most previously estimated models have undoubtedly misspecified the interest rate variable iii interest rate variability is another important determinant of real money demand and iv in contrast of previous studies the long run scale variable is real gdp whereas real consumer spending is the short run scale variable the sample period examined is 1953 1 to 1991 4

the implications of inflation in an estimated new keynesian model abstract this paper studies the steady state and dynamic consequences of inflation in an estimated dynamic stochastic general equilibrium model of the u s economy it is found that 10 percentage points of inflation entail a steady state welfare cost as high as 13 of annual consumption this large cost is mainly driven by staggered price contracts and price indexation the transition from high to low inflation inflicts a welfare loss equivalent to 0 53 of annual consumption the role of nominal real frictions as well as that of parameter uncertainty is also addressed

is the consumption income ratio stationary evidence from panel unit root tests this paper provides evidence on the stationarity of the consumption income ratio from a panel of 20 oecd countries using recently developed panel unit root tests which avoid the problem of low power associated with conventional unit root tests our findings suggest that the consumption income ratios in the oecd countries are generated by a nonstationary stochastic process

the demand for money and non gdp transactions abstract this paper argues that transactions in non gdp items have an important influence on the level of money demand the paper provides empirical estimates of models of both m 1 and m 2 money demand that include variables proxying for the volume of transactions in real estate and financial assets these variables have the theoretically predicted positive sign and are statistically significant their inclusion also improves out of sample forecasts

investigating stability and linearity of a german m1 money demand function starting from a linear error correction model ecm the stability and linearity of a german m1 money demand function are investigated applying smooth transition regression techniques using seasonally unadjusted quarterly data from 1961 1 to 1990 2 it is found that the money demand equation considered is both linear and stable after extending the sampling period until 1995 4 a clear structural instability due to the monetary unification on 1 july 1990 is found and subsequently modelled a non linear specification for the extended period is presented and discussed copyright 1999 john wiley sons ltd

money demand and the effects of fiscal policies this paper reexamines the choice of the scale variable in the money demand function a variety of evidence suggests that consumer spending is a better scale variable than gnp changing the money demand specification along these lines can profoundly affect the standard keynesian analysis of a tax cut copyright 1986 by ohio state university press

the effects on output of money growth and interest rate volatility in the united states in october 1979 the federal reserve began a policy of disinflation and also stopped stabilizing interest rates subsequently interest rates became much more volatile using a methodology advanced by barro this paper estimates what this change in policy did to output in the united states the paper finds that the stagnation of the u s economy since 1979 stemmed almost as much from increased interest rate volatility as from reduced money growth the paper also assesses the extent to which increased volatility of money growth has contributed to stagnation it finds no evidence of any appreciable contribution the paper concludes that stabilizing interest rates is probably sensible monetary policy

monetary economic myth and econometric reality few of the main macro economic forecasting systems can produce sensible forecasts without the tender loving care of their proprietors many econometric equations in com mon use show significant deterioration in the accuracy with which they characterise data as time passes and many economists are sceptical about empirical evidence feeling it lacks credibility monetary relationships have the dubious distinction of being among the leaders in this field as witnessed by the very large mispredictions of m1 models in the usa over what is now known as the missing money period 1973 76 as well as during the recent great velocity decline 1979 82 in the uk models of m1 and m3 demand experienced large structural breaks following the competition and credit control regu lation changes and the move to floating exchange rates perhaps it is no surprise that goodhart s law should have been formulated with respect to money demand equations

tariff tax reforms in large economies this paper studies tariff tax reforms in a two region global new keynesian model composed of a developing and an advanced region in our baseline calibration a revenue neutral reform that lowers tariffs in developing countries can reduce domestic welfare the reason is that the increase in developing countries welfare due to higher output is dominated by the welfare losses stemming from the deterioration of the terms of trade on the other hand the reform increases output and welfare in the advanced countries and in the world as a whole the effects that we highlight have not been studied in previous contributions to the literature which looks at tariff tax reforms using a small open economy framework nominal rigidities have important implications for adjustment dynamics in our model in the case of a point for point reform for example price stickiness implies that the international dynamics of output is reversed compared to a revenue neutral reform

leakages from the money demand function the performance of alternative scale variables is explored in a simple demand function for narrow money sequential test establish consumers expenditure as the preferred measure the implications for fiscal policy and the paradox of thrift are outlined

complementary credit networks and macroeconomic stability switzerland s wirtschaftsring abstract the swiss wirtschaftsring economic circle credit network founded in 1934 provides residual spending power that is highly counter cyclical individuals are cash short in a recession and economize by greater use of wir credits a money in the production function mipf specification implies that transactions in wir form a stabilizing balance that makes up for the lack of ordinary currency thus unlike the ordinary money wir money is negatively correlated with gdp in the short run this implication is confirmed by empirical estimates such credit networks play a stabilizing role that should be considered in monetary policy

reinterpreting the dhsy 1978 consumption function with hindsight the justification for davidson hendry srba and yeo s dhsy s selection of their favoured equation is shown to be based upon contradicting assumptions about inflation the empirically supported model is argued not to have a theoretically justified error correction interpretation the exclusion of the intercept biases the error correction term such that it becomes significant and negative but undermines the theoretical plausibility of the long run target more generally the statistical need to include an intercept in any regression to avoid parameter bias is demonstrated the rise in inflation in the 1970s is not considered to be a credible explanation of the fall in the average propensity to consume apc from the 1950s and is shown to have questionable empirical support when a below unit income elasticity is allowed for the recent articles which have found support for dhsy s favoured formulation augmented by time varying parameters using the most contemporary uk data should be viewed with caution new interpretations for the dhsy model s persistent success are called for if it is not to be considered that dubious regressions have been resurrected

monetary fiscal policy interactions and fiscal stimulus abstract increases in government spending trigger substitution effects both inter and intra temporal and a wealth effect the ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior studies that impose active monetary policy and passive fiscal policy typically find that government consumption crowds out private consumption higher future taxes create a strong negative wealth effect while the active monetary response increases the real interest rate this paper estimates markov switching policy rules for the united states and finds that monetary and fiscal policies fluctuate between active and passive behavior when the estimated joint policy process is imposed on a conventional new keynesian model government spending generates positive consumption multipliers in some policy regimes and in simulated data in which all policy regimes are realized the paper reports the model s predictions of the macroeconomic impacts of the american recovery and reinvestment act s implied path for government spending under alternative monetary fiscal policy combinations

money financed fiscal stimulus the effects of implementation lag abstract previous studies argue that based on the new keynesian framework a fiscal stimulus financed by money creation has a strong positive effect on output under a reasonable degree of nominal price rigidities this paper investigates the effects of an implementation lag in a money financed fiscal stimulus on output we show that if a money financed government purchase has a time lag between the decision and the implementation 1 it may cause a recession rather than a boom when the economy is in normal times 2 it may deepen a recession when the economy is in a liquidity trap 3 the longer the implementation lag the deeper the recession and 4 the depth of the recession depends on the interest semi elasticity of money demand our results imply that if money demand is unstable the money financed fiscal stimulus with an implementation lag may have unstable effects on output in contrast to the debt financed fiscal stimulus

exchange rate determination the role of factor price rigidities and nontradeables this paper introduces factor labor markets into the intertemporal monetary model of obstfeld and rogoff and combines this richer market structure with a new utility independent representation of nontradeables this allows us to explore the international monetary transmission mechanism for factor price wage rigidities under different degrees of macroeconomic openness factor price rigidities imply similar properties for the international transmission mechanism as domestic producer price rigidities nontradeables give raise to interesting new effects under asymmetric monetary shocks they create short run ppp deviations increase exchange rate volatility relative to price level volatility and reduce positive consumption and negative output comovements 2000 elsevier science b v all rights reserved

seasonal fluctuations and the demand for money the reaction of money holders to the systematic seasonal changes in the level of transactions represents an interesting experiment for learning about the money demand function an analysis of the seasonal fluctuations of the real quantity of money and several measures of transactions in the united states germany the united kingdom and canada reveals the following first consumption expenditures in semidurables nondurables and services appears to be a good proxy for transactions in a money demand function and superior to gross domestic product or consumption expenditures second the transactions elasticity of the demand for money is substantially lower than one

analyzing the stability of demand for money equations via bounded influence estimation techniques a robust estimation technique bounded influence instrumental variables is applied to an error correction model formulation of a u s money demand equation the weights generated by bounded influence instrumental variables are used to diagnose structural instability in the specification of the equations and their error processes these techniques are shown to be valuable additions to the empirical researchers toolkit and have been implemented in commonly used econometric software copyright 1990 by ohio state university press

deficits and the demand for money in recent years the large budget deficits of the federal government have renewed interest in the effects of government debt on private sector behavior to date empirical research has focused on the relationship between debt and two key variables consumption and interest rates by contrast empirical research on the effects of government debt on other variables of interest to macroeconomists is limited this paper examines the relationship between government debt and one such variable real money balances the neglect of government debt as a determinant of money demand is surprising many traditional macroeconomic models such as blinder and solow s 9 influential work include government debt as an argument to the money demand function moreover macroeconomic theorists have long been aware that a government debt money demand relationship has important implications for the efficacy of fiscal policy 2 this paper examines the relationship between government debt and real money holdings over the 1950 1990 period a positive money debt relationship was previously noted by butkiewicz 12 and deravi hegji and moberly 15 hereafter referred to as dhm our work improves upon this research in two ways first in contrast to butkiewicz 12 and dhm 15 we investigate the time series properties stationarity cointegration of relevant variables second we distinguish between supply side and demand side explanations of the debt money relationship the explanation advanced by butkiewicz 12 and dhm 15 is that an increase government debt is perceived by the private sector as an increase in net wealth and hence should increase money demand 3 this explanation ignores a potentially important connection between government debt and money supply if the federal reserve monetizes debt and if the private sector s adjustment to this monetization is lagged then debt and real money balances will exhibit a positive correla

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

fiscal consolidation under fixed exchange rates abstract we present the fixed exchange rate version of the obstfeld and rogoff model and analyze the international transmission of fiscal policy shocks the welfare effects of an unanticipated contraction in government expenditure in the home country are shown to depend crucially on the way in which world money stock is set if home authorities alone are responsible for pegging the exchange rate a fiscal adjustment leads to a decrease in the real interest rate stimulates private consumption and limits the contraction in world output compared with a situation in which a cooperative scheme is implemented the model is then used to propose a new interpretation of recent events in the eu countries that have enacted restrictive fiscal policies while pegging their currencies to the dm

boundary optima and the theory of public goods supply abstract this paper derives a generalized optimality condition that is valid for all boundary optima in an economy with many public goods and one private good this condition is then used to show that there is an open subset of pareto optima where samuelson s condition does not hold finally it is shown that allocation and distribution are inextricable at these optima even under conditions that guarantee independence of allocation and distribution at interior optima

is it the weather we show that results in the recent strand of the literature which tries to explain stock returns by weather induced mood shifts of investors might be data driven inference more specifically we consider two recent studies kamstra mark j kramer lisa a levi maurice d 2003a winter blues a sad stock market cycle american economic review 93 1 324 343 cao melanie wei jason 2005 stock market returns a note on temperature anomaly journal of banking and finance 29 6 1559 1573 that claim that a seasonal anomaly in stock returns is caused by mood changes of investors due to lack of daylight and temperature variations respectively while we confirm earlier results in the literature that there is indeed a strong seasonal effect in stock returns in many countries stock market returns tend to be significantly lower during summer and fall months than during winter and spring months as documented by bouman and jacobsen bouman sven jacobsen ben 2002 the halloween indicator sell in may and go away another puzzle american economic review 92 5 1618 1635 there is little evidence in favor of a sad or temperature explanation in fact we find that a simple winter summer dummy best describes this seasonality our results suggest that without any further evidence the correlation between weather related variables and stock returns might be spurious and the conclusion that weather affects stock returns through mood changes of investors is premature

convergence theorems on the core of a public goods economy sufficient conditions abstract it is shown if all consumers are either asymptotically satiated or strictly nonsatiated in public goods then the core converges to the lindahl allocations as the economy grow without bound asymptotic satiation implies that only a vanishing fraction of the private good is devoted to public goods production as the economy gets large strict nonsatiation on the other hand implies that essentially all of the private good is devoted to public goods production in the limit it is interesting that these two conditions are independently sufficient for core convergence despite their completely opposite implications for the asymptotic nature of the lindahl allocations journal of economic literature classification numbers h41 d51 c71

the equilibrium relationship among money income prices and interest rates evidence from a threshold cointegration test the long run equilibrium relationship among money income prices and interest rates in japan is investigated by the threshold cointegration test which allows for asymmetric adjustment introduced by enders and siklos 2001 the threshold cointegration approach provides clear evidence of the cointegration relationship characterized by asymmetric adjustment by allowing for asymmetric adjustment results are obtained showing the stability of the money demand function similar to lucas 1988 who pointed out that the money demand function is stable if unit income elasticity is imposed in particular the estimated results show that the adjustment process toward equilibrium is highly persistent above an appropriately estimated threshold whereas the adjustment process toward equilibrium quickly converges below it this finding indicates that deviations from equilibrium resulting from increases in money or decreases in income and prices are highly persistent

an investigation of the long run properties of aggregate non durable consumers expenditure in the united this paper estimates the effects of the modeling of nondurable consumption in the light of the five years of new data since the publication of the paper by j e h davidson et al 1978 and the development of the new cointegration technique of r f engle and c w j granger 1987 existing models are found to be inadequate on two grounds they fail parameter stability tests and they do not contain a suitable equilibrium specification the paper uses the cointegration approach to search for an encompassing model that is both stable and cointegrates the main finding is that the analysis must be extended to allow for differential income effects caused by changing higher rate income tax bands copyright 1989 by royal economic society

aggregate consumption and the distribution of income in the united kingdom an econometric analysis blinder i975 explained this omission by arguing that with the ascendancy of the friedman 1957 and modigliani and brumberg i954 models of consumer behaviour the view that income distribution affected aggregate consumption fell into disrepute in academic circles it was supplanted by the view that marginal and perhaps even average propensities to consume are constant over the income distribution pp 447 8 the life cycle model as is well known derives the aggregate consumption function from the hypothesis that the consumer chooses the time path of consumption which maximises lifetime utility subject to the constraint that the present discounted value of all consumption plus the present discounted value of the bequest if any is equal to lifetime disposable resources a consequence of such a hypothesis is that consumption at each instant is proportional to lifetime disposable resources with the constant of proportionality dependent only on age length of life the rate of interest and tastes in their empirical work friedman and modigliani may also have had to ignore income distribution due to lack of data however blinder 1975 went on to show that even under the life cycle hypothesis provided that the marginal utility of bequests say f was different

financial innovation and money demand application to chile and mexico this paper reexamines one estimation of money demand equations using quarterly data for chile and mexico the authors find no evidence of cointegration of traditional long run money demand equations in light of this evidence they argue that there is an important permanent component of the demand for money not captured by traditional variables interest rates and income the authors call this phenomenon financial innovation and they include it in the traditional specification by assuming that it follows a random walk copyright 1993 by mit press

determining the appropriate deflation of nominal magnitudes in the uk consumption function a nonnested test approach this paper is concerned with the deflator s used to obtain series measured in real terms in the consumption function since the precise deflator s to be used in any particular specification is not uniquely determined by theoretical considerations alone we consider ways of approaching the issue empirically the starting point is to rearrange any given specification of the consumption function so that a nominal consumption variable is explained this implies that different deflators for consumption and other variables in the initial specification which are expressed in real terms define non nested models we therefore examine the issue of the appropriate method of deflation used non nested tests we consider the davidson hendry srba and yeo specification of the quarterly uk non durable consumption function and find that the preferred method of deflating consumption and income variables is to use the total durable and non durable consumption deflator we also examine the quarterly uk consumption

the carlson parkin method applied to nz price expectations using qsbo survey data abstract the standard carlson parkin economica 1975 42 123 138 method is used to estimate the parameters of producers prices expectations non nested tests suggest that the carlson parkin method is superior to the use of the simple balance statistic a non linear extension of the carlson parkin technique is estimated and no evidence is found to support the hypothesis that producers price expectations are drawn from skewed or kurtotic distributions

is non monetarist arithmetic just as unpleasant what should the central bank do if the fiscal authority persists in running a deficit if the monetarist policy prescription of bond financing deficits is adopted mccallum 8 and others have shown that the real growth rate must exceed the after tax real interest rate if macroeconomic instability is to be avoided analysts such as miller and sargent 10 and burbidge 1 doubt whether this condition is met and thus argue in favor of greater flexibility in the rate of monetary growth but will that lead to instability as well is the requirement for a unique solution and macroeconomic convergence just as stringent under the non monetarist option of money financed deficits if so monetarists can deflect criticism of their financing option from those who argue money financing is preferred on feasibility grounds this paper addresses this question and concludes that money financing involves much more pleasant arithmetic than does bond financing analysis is given for both closed and small open economies considering what is available in the existing literature the open economy extension may be the most important contribution of the paper in addition to addressing the feasibility of alternative financing options we use the model to comment on the welfare cost of inflation in an open economy environment the feasibility of money financed deficits has recently drawn renewed attention among macroeconomists erbas 2 using a model which imposes the ricardian equivalence hypothesis and assumes no growth concludes that money financing is preferred as an automatic stabilizer as it offers greater short run stability of the level of income scarth 14 comes to the same conclusion using a model which does not impose the ricardian equivalence hypothesis but which allows economic growth liviatan 6 and mitchell 11 investigate the feasibility of bond and money financing using long run models of a closed economy in which government bonds constitute a part of net wealth in this paper we consider both open and closed economy long run models and we adopt the ricardian equivalence hypothesis we emphasize ricardian equivalence since most monetarists are comfortable with this assumption thus unlike the previous long run studies we examine the feasibility of monetarist versus non monetarist financing options using a model acceptable to most monetarists this is important when the results do not support monetarism the remainder of the paper is organized as follows the closed economy analysis is given in section ii the open economy case is discussed in section iii and concluding remarks are contained in section iv

do real balance effects invalidate the taylor principle in closed and open economies this paper examines the determinacy implications of forecast based monetary policy rules that set the interest rate in response to expected future inflation in a neo wicksellian model that incorporates real balance effects we show that the presence of such effects in closed economies restricts the ability of the taylor principle to prevent indeterminacy of the rational expectations equilibrium the problem is exacerbated in open economies particularly if the policy rule reacts to consumer price rather than domestic price inflation however determinacy can be restored in both closed and open economies with the addition of monetary policy inertia

exchange rates and monetary policy in emerging market economies this paper investigates the effects of exchange rate regimes and alternative monetary policy rules for an emerging market economy that is subject to a volatile external environment in the form of shocks to world interest rates and the terms of trade in particular we highlight the impact of financial frictions and the degree of exchange rate pass through in determining the relative performance of alternative regimes in stabilizing the economy in the face of external shocks our results are quite sharp when exchange rate pass through is high a policy of non traded goods inflation targeting does best in stabilizing the economy and is better in welfare terms when exchange rate pass through is low however a policy of strict cpi inflation targeting is better in all cases a fixed exchange rate is undesirable in addition financial frictions have no implications for the ranking of alternative policy rules

on cash in advance models of money demand and asset pricing this paper shows how a cash in advance model of money can be written in a way that combines a simple yet empirically defensible money demand function with an asset pricing equation that is similar to the standard barter economy euler equations return premia are determined as in the barter exchange model except that a short term risk free nominal interest rate enters into the first order conditions in special cases asset prices satisfy the barter economy euler equations exactly in the empirical analysis the interest rate factor adds some explanatory power but both the barter and the monetary asset pricing model perform rather poorly copyright 1991 by ohio state university press

output the stock market and interest rates this paper develops a simple model of the determination of output the stock market and the term structure of interest rates the model is an extension of the is lm model and borrows from it the assumption that output is determined by aggregate demand and that the price level can only adjust over time to its equilibrium value however whereas the is lm emphasizes the interaction between the interest rate and output this model emphasizes the interaction between asset values and output asset values rather than the interest rate are the main determinants of aggregate demand and output current and anticipated output and income are in turn the main determinants of asset values it is this interaction that the model intends to capture its goal is to characterize the joint response of asset values and output to changes in the environment such as changes or announcement of changes in monetary and fiscal policy as the above brief description makes clear anticipations are central to the story the assumption made in this paper will be one of rational expectations the paper is organized as follows section i describes the model and sections ii iv characterize the behavior of the economy under the extreme but convenient assumption that prices are fixed forever sections v and vi extend the analysis to the case where prices adjust over time to their equilibrium value

the demand for money in argentina 1978 1987 before and after the austral program in this study a monthly money demand function for argentina is estimated for a period that ends one month before the austral program may 1985 the performance of the traditional econometric approach is compared with the new cointegration approach to time series econometrics the comparison is carried out by a postsample forecast of the demand for money for a period of two years after the stabilization until july 1987 the cointegration approach is found superior to the traditional approach the first produces a relatively stable money demand whereas the second yields an unstable one

the impact of changes in human fertility on poverty household survey data for developing and transitional economies are used to estimate the effect of fertility crude birth rate net of infant deaths on private consumption poverty cross national regressions indicate that higher fertility increases poverty both by retarding economic growth and by skewing distribution against the poor our median country in 1980 had dollar a day poverty incidence of 18 9 per cent had it reduced its fertility by four per 1 000 throughout the 1980s the sample median fall it is estimated that incidence would have been reduced to 13 9 per cent the growth and distribution effects being roughly equally responsible for this reduction

nonsecular regularities in returns and volume this study addressed u s stock daily returns and volume around days when the market is open that correspond to religious or cultural occasions specifically st patrick s day and the jewish high holy days of rosh hashanah and yom kippur on rosh hashanah and yom kippur volume was found to be down relative to volume on all trading days in the sample the reason may be that the nonfinancial opportunity cost of trading is high for a considerable number of traders on these days returns were significantly higher on the days preceding st patrick s day and rosh hashanah which is consistent with the notion that market returns reflect the festive nature of these occasions evidence was also found of significantly negative returns after yom kippur in the second half of the sample period which accords with the idea that the market reflects the solemn nature of this occasion overall the results are consistent with the view that mood is a viable explanation for some market movements

excess labour and the business cycle a comparative study of japan germany the united kingdom and the united states against the background of firm specific human capital theory this paper investigates empirically the relative propensity of manufacturing industries in japan germany the united kingdom and the united states to hold excess labour over the business cycle both stock and utilization dimensions of the labour input are integrated into the study throughout discussion is linked to earlier research that has analysed the relative international performance of the japanese labour market

forecasting aggregate consumers expenditure in the u k using the dhsy model the performance of the dhsy model in predicting the growth of aggregate consumers expenditure in the uk over the period 1985 1988 is examined the model is applied to four different combinations of consumption variable and data type results show in all cases the predictive performance of the dhsy model to be poor however applied to seasonally adjusted data an improvement can be achieved by allowing for systematic variation in coefficients in particular a variable coefficient dhsy model displays no tendency to underpredict the growth of total consumers expenditure and accurately captures the volatility of non durable expenditure

the appropriate scale variable in the u s money demand an application of nonnested tests of consumption versus income measures the purpose of this article is to employ several nonnested procedures to empirically test the proposition put forward by mankiw and summers that consumption rather than income is the appropriate scale measure in the money demand function real income real disposable income consumer spending on nondurables personal consumption expenditures and total private spending are tested as candidates for the scale variable tests are carried out for both m1 and m2 concepts of money the results based on both m1 and m2 support the mankiw summers position but the results based on m2 are not as strong as those based on m1 implications for fiscal and monetary policies are discussed

money demand heterogeneity and the great moderation abstract a forward looking model of the demand for money based on heterogeneous and sluggish portfolio adjustment can simultaneously account for the low short run and high long run semi elasticities reported in the literature the parameter estimates from the model for the short run and long run interest semi elasticities are 1 04 and 13 16 respectively a simulated version of the model suggests that the great moderation can be partially attributed to financial innovations in the late 1970s when moving toward a more flexible portfolio the model can account for almost one third of the observed decline in the volatilities of output consumption and investment

tax loss selling and the january effect evidence from municipal bond closed end funds this paper provides direct evidence supporting the tax loss selling hypothesis as an explanation of the january effect examining turn of the year return and volume patterns for municipal bond closed end funds which are held mostly by tax sensitive individual investors we document a january effect for these funds but not for their underlying assets we provide evidence that this effect can be largely explained by tax loss selling activities at the previous year end moreover we find that funds associated with brokerage firms display more tax loss selling behavior suggesting that tax counseling plays a role among the numerous stock return anomalies probably none has generated more interest than that of the turn of the year or january effect the phenomenon in which small capitalization stocks realize unusually high returns in early january 1 the literature offers a number of hypotheses to explain this phenomenon including the tax loss selling hypothesis the window dressing hypothesis the insider trading information release hypothesis and the seasonality of the risk return relation hypothesis given existing evidence in some support for the first two hypotheses the debate continues with respect to which of these the tax loss selling of individual investors or the window dressing of

monetary independence under bretton woods perspectives from a stochastic maximizing model research based on the kouri porter 1974 model of international capital flows suggests that the central banks of nonreserve countries enjoyed considerable monetary independence during the bretton woods era this paper is a theoretical and empirical reassessment of this conclusion using a stochastic maximizing model it is shown that the existence of imperfect asset substitutability does not guarantee monetary control at the empirical level the estimated offset coefficients for four industrialized countries are consistent with zero monetary independence

the stationarity of consumption income ratios evidence from minimum lm unit root testing abstract previous research concerning the stationarity of the consumption income ratio is extended via the application of the minimum lm unit root tests of lee and strazicich 2003 lee j and strazicich m 2003 minimum lm unit root test with two structural breaks review of economics and statistics 85 1083 1089 it is found that incorporation of structural change under the null reverses earlier findings of non stationarity with the unit root hypothesis rejected for all 20 oecd economies examined

real exchange rates and macroeconomics evidence and theory since the early 1980s a large body of research has thrown doubt on the relevance of macroeconomic models for understanding exchange rates the authors argue that a balanced reading of recent literature in exchange rate economics gives a more optimistic assessment many studies have established the pertinence of long run purchasing power parity ppp and the explanatory power of macroeconomic fundamentals in real exchange rate fluctuations a reasonably strong case can be made for a traditional macroeocnomic interpretation of real exchange rates which emphasizes short run price stickiness but long run ppp but a central new ingredient in this interpretation is the presence of international commodity market segmentation and persistent deviations from the law of one price an example is given of a dynamic general equilibrium model that can reproduce some of the observed features of real exchange rate fluctuations

how sticky is sticky enough a distributional and impulse response analysis of new keynesian dsge models in this paper we add to the literature on the assessment of how well data simulated from new keynesian dynamic stochastic general equilibrium dsge models reproduce the dynamic features of historical data in particular we evaluate sticky price sticky price with dynamic indexation and sticky information models using impulse response and correlation measures and via implementation of a distribution based approach for comparing possibly misspecified dsge models using simulated and historical inflation and output gap data one of our main findings is that for a standard level of stickiness i e annual price or information adjustment the sticky price model with indexation dominates other models we also find that when a lower level of information and price stickiness is used i e bi annual adjustment there is much less to choose between the models see bils and klenow 2004 for evidence in favor of lower levels of stickiness this finding is due to the fact that simulated and historical densities are much closer under bi annual adjustment

the demand for money in the united states evidence from cointegration tests this paper uses recent cointegration test procedures to investigate the underlying economic relationship between real money balances real income and interest rates for the united states unlike recent studies of money demand the authors analysis uses quarterly data spanning the period 1915 88 thus providing a sample encompassing a wide variety of economic experiences the evidence presented indicates that the broader m2 measure of money is the preferable measure with which to consider the long run effects of monetary policy copyright 1991 by ohio state university press

cointegration and dynamic time series models abstract this paper provides a survey of some of the recent developments in the field of econometric modelling with cointegrated time series in particular we describe the testing and estimation procedures which have become increasingly popular in the recent applied literature in addition to the two stage procedure proposed by engle and granger we consider extensions to the modelling of dynamic models with cointegrated variables such as the estimation of models with multiple cointegration vectors simultaneous systems models with seasonally integrated and cointegrated variables furthermore we illustrate the practical application of the techniques describes in the paper by means of a tutorial data set

the samuelson condition and the lindahl scheme in networks abstract we study optimal provision of public goods in the network showing that the samuelson condition and the lindahl scheme can both be substantially extended to characterize the expenditure on such public goods couched in terms of the structure of the network the extended samuelson condition and lindahl scheme formulate precisely how the local publicness of a local public good fundamentally determines its optimal provision and the personalized price that the lindahl tax payer faces independence of the optimal allocation from the distribution of resources at interior samuelsonian solutions in the network generally fails to hold even for the bergstrom cornes preferences

the uk consumption function and structural instability improving forecasting performance using a time varying parameter approach previous studies indicate that the poor forecasting performance of constant parameter uk consumption expenditure models is caused by structural instability in the underlying data generating process typically this instability is removed by reparameterization within the constant parameter framework an alternative modelling strategy is to allow some or all of the parameters to vary over time a uk non durable consumption expenditure model with time varying parameters is developed based on the permanent income hypothesis of friedman 1957 this model takes into account temporal changes in the average and marginal propensities to consume the variation in the parameter estimates is given an economic interpretation in terms of the influence of omitted variables namely uk financial liberalization and expectational changes the forecasting performance of this model is superior to that of two widely used constant parameter models further tests show that even if these constant parameter models are respeci

fundamental nonconvexities in arrovian markets and a coasian solution to the problem of externalities abstract d starrett j econ theory 4 1972 180 199 argues that the presence of externalities implies fundamental nonconvexities which cause arrow markets to fail while this is true we argue this failure is due to the structure of the arrovian markets that starrett uses and not to the presence of externalities as such we provide an extension of a general equilibrium public goods model in which property rights are explicitly treated nonconvexities are not fundamental in this framework we define a notion of coasian equilibrium for this economy and show first and second welfare theorems in this context the first welfare theorem is a type of coase theorem journal of economic literature classification numbers d62 h41
