an econometric model of crowding out of lower education levels abstract unemployment in the netherlands has risen strongly in recent years there are large differences in unemployment rates between education levels according to neo classical theory these differences should be explained by distorted relative prices or by lack of human capital in this paper we test an alternative explanation according to this view the high unemployment rate for lower education levels is caused by excess labour supply highly educated people take the jobs which could be occupied by less educated people to test this view a regression model is developed estimation results indicate that differences in unemployment rates can indeed be explained by excess supply of qualified labour

adaptive versus rational expectations and the fisher effect substantial controversy remains over the causes of interest rate fluctuations this controversy frequently focuses on the role of expected inflation the theoretical determinats of the nominal rate are examined usig the is lm as model and it is shown that the augmented fisher equation is sensitive to the expectations generating mechanism the model assumes that the nominal rate ceteris paribuschanges one for one with expected inflation the total impact however may take any value from zero to one the empirical analysis sequentially estimates reduced form equations based on adaptive and rational expectations the results confirm prior findings that nominal rates do not adjust one for one with inflation the results also yield some insight on the applicability of the assumption of rational versus adaptive expectations

stock returns inflation and the phillips curve in recent years the negative relation between stock returns and inflation has been rigorously investigated studies by lintner 25 bodie 1 jaffee and mandelker 21 nelson 28 fama and schwert 11 and gultekin 17 to name but a few consistently show that stock returns are negatively associated with inflation if associated at all and conclude that the fisher hypothesis does not hold for stocks explanations for this finding are equally abundant for instance fama 10 postulates that the observed negative association is largely a spurious phenomenon a conclusion he justifies by maintaining that it is consistent with a simple money demand quantity theory world geske and roll 15 extend this line of thought by developing a more complex macro economic model that includes such items as unemployment corporate earnings and government financing following a somewhat different approach ram and spencer 32 reexamine fama s work by augmenting the fisher equation to include the phillips curve hypothesis they conclude that there is a positive association between inflation and real activity and a negative relationship between real stock returns and real activity a position that contradicts fama s findings a problem common to the above explanations is that a general equilibrium framework is not employed the purpose of this study therefore is to further develop this work by examining the relationships among real stock returns inflation and unemployment using a general equilibrium model a nonspurious negative relation of real interest and inflation is employed that is based on the levi and makin studies 23 24 it is shown that the natural rate of unemployment phenomenon which causes the phillips curve to shift also simultaneously causes the real interest rate inflation relation to shift using this framework the hypothesis that the real stock return inflation relation shifts concurrently with the phillips curve is empirically tested the hypothesis is not rejected this suggests that the usual simple regression of stock returns on inflation is misspecified so that the slope estimate is not as steep as the true one the plan of the paper is as follows the concurrency of the shift in the real interestinflation relation and the phillips curve is demonstrated in the next section in section iii the shift in the phillips curve is tested by the brown durbin and evans method 3 then using dummy variables to represent the shifting phenomenon of the phillips curve empirical

a respecified tax adjusted fisher relation how much will a 1 increase in expected inflation increase nominal interest rates irving fisher s famous equation implies that nominal interest rates will rise in proportion to an increase in expected inflation darby and feldstein correcting the fisher equation for taxation predict a nominal interest rate increase of 1 1 t where t is the marginal tax rate i e if t 3 then a 1 increase in expected inflation should cause a 1 4 rise in interest rates empirical evidence however suggests that the rise in interest rates is much smaller than the darby feldstein prediction estimates are around 9 varying mostly between 5 and 1 15 which is much closer to fisher s original prediction it is important to know the size of the interest rate response to inflation expectations in a world in which inflation and interest rates are volatile and in which tax laws are designed to influence savings and investment through interest rates in this paper we attempt to close the gap between theorized and estimated effects of inflation by incorporating into the fisher equation two important aspects of the u s tax code historic cost depreciation and the lower tax rate on capital gains our model shows that the effect of expected inflation on interest rates is dampened by the lower benefits from depreciation deductions arid the capital gains tax our corrected fisher equation predicts a 1 12 nominal interest rate increase rather than the 1 4 increase implied by the darby feldstein model the our model closes about 56 of the gap between theory and empirical evidence the remainder could be closed by additional refinements in the model or better empirical modeling

the purchasing power of money and nominal interest rates a re examination while it has been known for some time that under uncertainty the original version of the fisher hypothesis is not precisely correct empirical researchers have largely ignored this fact such an omission has possibly resulted in erroneous conclusions concerning other hypotheses most notably the impact of prices on the real economy this paper clarifies some of the previous interpretations of the existing empirical literature and provides a theoretical version of the relation between prices and interest rates empirical tests based on both the livingston survey data and data from time series forecasting models provide support for the fisher effect and the hypothesis that only covariance risk is priced in the treasury bill market one of the basic hypotheses concerning rationality in financial markets is based on statements generally attributed to fisher 18 fisher argued that the nominal or money rate of return on an asset should compensate an investor for his or her required real rate of return and changes in the purchasing power of money for the uncertainty case fisher replaced known purchasing power changes with the expected inflation rate whereas the fisher relationship under certainty is well defined his basic theorem under uncertainty is not precise as fama 15 has argued it is changes in the purchasing power of money not the inflation rate that should concern investors under uncertainty the expected value of one is not by jensen s inequality the inverse of the expected value of the other moreover fama and farber 16 grauer and litzenberger 20 and benninga and protopapadakis 3 have shown that when investors are risk averse the fisher relationship will generally not hold even after adjustment has been made for the distinction between purchasing power changes and the inflation rate in particular these authors show that an adjustment must be made for the fact that the real rate of return on nominal bonds is random while these issues have been discussed in the theoretical literature they have largely been ignored in the empirical work on this topic given the fact that nominal rates do not seem to adjust as rapidly to price changes as fisher hypothesized numerous empirical researchers have expanded the basic fisher model in an attempt to explain this empirical anomaly these extensions include the incorporation of a inflation rate variability and the growth in real output

price instability and inflation some tests based on rational expectations models abstract we test for a group of fourteen latin american countries the hypothesis that as inflation accelerates it also becomes more volatile our analysis uses time series data a less arbitrary measure of inflation volatility rational expectations models and seemingly unrelated regressions the empirical evidence supports the above hypothesis and strengthens the case against inflationary policies in latin america

central bank independence economic behavior and optimal term lengths the authors parameterize central bank independence in terms of partisanship and term length focusing on the implications of alternative policy structures for real economic activity while long terms of office for the central banker can reduce the role of electoral surprises term lengths that are too long are costly if societal preferences are subject to permanent shifts the appointment of a conservative central banker increases the optimal term length and leads to lower average inflation but need not increase the volatility of output copyright 1996 by american economic association

a model of the financial firm with imperfect asset and deposit elasticities abstract the paper develops an intertemporal model to estimate the production technology of financial firms such as banks price taking is testable in each separate market for assets and liabilities and competitive price taking is a nested special case such tests are applied both to outputs and inputs empirical results for a sample of banks in new york and new jersey indicate that price taking applies only in markets for labor and time deposits in markets for loans demand deposits cash and materials the price taking hypothesis is not accepted

does the federal reserve affect asset prices abstract the federal reserve is probably one of the institutions most closely monitored by investors this indicates that investors believe the actions of the fed have implications for asset prices to this date the trading activities of the fed in the financial markets have not been examined to see how the fed influences asset prices using daily data on open market operations omos and asset prices this study fills this void one finding of the paper is that omos granger cause both short and long term interest rates furthermore the sign of the relationship confirms the existence of the liquidity effect given that its trades represent a small portion of the market volume how the fed influences bond prices is a puzzle the only reasonable explanation is that the fed s trades have high information content judging by the impulse response paths the reaction of interest rates to open market operations is fast additionally it appears that monetary policy has a lasting impact on interest rates

can futures market data be used to understand the behavior of real interest rates this paper examines whether futures market data can be used to understand the behavior of real interest rates several ways of examining the data indicate that futures market data are not particularly informative about real interest rates not only does this evidence cast some doubt on results in previous research that make use of futures market data to draw inferences about real interest rates but it also indicates that future research on real interest rates may need to turn to a different line of attack understanding the behavior of real interest rates is a central issue in financial economics in previous research on this topic several approaches have been used to measure real interest rates in one approach real interest rates have been calculated by subtracting survey data on inflation expectations such as the livingston data from nominal interest rates the problem with survey based measures of real interest rates is that they are only as good as the survey measure of inflation expectations and there may be little incentive for the survey respondents to answer accurately an even more telling criticism of survey based measures often ignored in the literature is that the behavior of market expectations in driven by economic agents ai the margin who are eliminating unexploited profit opportunities market expectations are unlikely therefore to be well measured by the average expectations of survey respondents 2 because of doubts about survey based measures of real interest rates other

interest rate determination in a small open economy abstract this paper is an attempt to explain the behavior of ex ante real rates of interest in singapore during the period 1961 1981 this is done within a model which explicitly allows for the role of supply shocks inflation uncertainty and foreign interest rates

when and how much to talk credibility and flexibility in monetary policy with private information abstract this paper analyzes the role of noisy or imprecise announcements in mitigating the basic credibility problem in monetary policy based on a model where the monetary authority s private information gives rise to an unavoidable trade off between flexibility and credibility the analysis finds that noisy announcements can serve as a meaningful form of communication to make that trade off more favorable however such talk is not cheap the analysis predicts that those central banks who can speak more precisely are those who are less likely to speak at all

interest rates and the subjective probability distribution of inflation forecasts the interst rate effects of the first four moments of the subjective probability distribution of inflation forecasts from the asa nber survey are examined over the period 1968 4 1985 4 using tre asury bill yields as the nominal rate variable in the context of a re duced form fisher equation the authors find that inflation uncertain ty as measured by the average variance of the probability distributi ons of inflation forecasts to be insignificant however the average skewness and kurtosis variables which result from these probability distributions do significantly affect interest rates they interpret these effects as accounting for the level of risk or uncertainty abou t future inflation copyright 1988 by ohio state university press

art investment an empirical inquiry investment in art and especially in paintings by the masters is often considered to be highly profitable particularly in the united states but also in the richer european nations there is an even larger number of investors who believe that buying works of art is not only fun but also a good investment from a purely financial point of view american banks have recently strengthened this trend toward art as an investment by employing art investment counselors thus suggesting that it is a financially rewarding activity to engage in and also suggesting that superior knowledge helps to improve financial success in this market buying and selling art has in fact become an increasingly popular activity since the end of world war ii the auction houses report record turnovers and record prices are paid in increasingly rapid sequence in april 1987 van gogh s sunflowers was sold at christie s london for 39 9 million only to be surpassed in november 1987 by van gogh s irises sold by sotheby s new york for 53 9 million including the auction house s 10 percent commission this last painting had been bought by the seller s mother in 1947 for 84 000 less than 0 5 million in today s money which gives a real rate of return of about 12 percent per year these enormous prices that are paid today for some masterpieces create a widespread belief that the rate of return on such investments is in general and on average very high books devoted to the subject 40 385 27 24 12 215 et seq seem to confirm that the rate of return from investment in paintings at least during the 1950s and 1960s was far greater than the rate obtainable from comparable risky assets in financial markets that the financial profitability in the 1970s and 1980s is believed to be if anything even larger than before is confirmed by many articles in financial and investment newspapers and journals up to now only very few scientific studies of the subject exist but they also have serious limitations the most recent one by baumol 5 covers a period of over 300 years but ends in 1960 two other studies by anderson 1 and stein 42 extend up to the end of the 1960s but do not go any further all three studies are practically limited to transactions by anglo saxon auction

a theory of ambiguity credibility and inflation under discretion and asymmetric information this paper develops a positive theory of credibility ambiguity and inflation under discretion and asymmetric information the monetary policymaker maximizes his own politically motivated objective function that is positively related to economic stimulation through monetary surprises and negatively related to monetary growth the relative importance he assigns to each target shifts stochastically through time his current preference trade off is known to him but not to the public when choosing the state contingent path of money growth for the present and the future the policymaker compares the benefits from current stimulation with the costs associated with higher future inflation expectations current monetary growth conveys information to the public about future money growth because there is persistence in the policymaker s objectives although expectations are rational information is imperfect because monetary control procedures are imprecise as a result the public cannot correctly distinguish persistent changes of emphasis on different policy objectives from transitory monetary control errors the public becomes aware of changes gradually by observing past monetary growth credibility is defined in terms of the speed with which the public recognizes changes in the objectives of the policymaker credibility is lower the noisier monetary control and the more stable the objectives of the policymaker looser monetary control and a higher degree of time preference on the part of the policymaker induce him to produce higher and more variable monetary growth when the policymaker is free to determine the accuracy of monetary control he does not always choose the most effective control available in spite of the fact that monetary surprises always have an expected value of zero the reason is that ambiguous control procedures enable the policymaker to generate positive surprises when he cares more than on average about economic stimulation he leaves the inevitable negative surprises for periods in which he cares more about inflation prevention this result provides an explanation for the fed s preference for ambiguity recently documented by goodfriend 1986 the policymaker is more likely to pick more ambiguous control procedures the more uncertain his objectives and the higher his time preference the paper also provides a theoretical underpinning for the well documented crosscountry positive correlation between the level and the variability of inflation

direct price controls as a source of instability in the interest rate inflation rate relationship abstract we hypothesize that an efficient capital market is more concerned with effective inflation rates which investors experience than official ones which econometricians observe and that direct consumer goods price controls are likely to result in disparity between the two consequently direct price controls are also likely to affect the interest measured inflation rate relationship we ropose a dummy variable approach which enables us to explore empirically the effects of such controls on the interest inflation rate relationship in the context of dwyer s 1981 model using euro rates and inflation rates of the respective countries we explore the impact of the control programmes imposed in the 1970 s by governments of the united states canada and france france

announcements inflation targeting and central bank incentives this paper studies the incentives a central bank faces in announcing inflation targets when the central bank has private information about the economy and the public is uncertain about the central bank s preferences targeting rules in the absence of announcements reduce the inflationary bias of discretionary policy but they distort the central bank s response to private information about the economy this distortion is eliminated when the central bank is allowed to announce the inflation target announcements also affect credibility although the way they do so depends on the exact definition of credibility that is employed in standard models of monetary policy in which dynamic inconsistency plays a prominent role announcements from the central bank about its policy inten tions are not believable the central bank has an incentive to lie yet central banks often do make announcements and they are legally required to do so in some cases the bank of england for example must issue periodic inflation reports the chairman of the federal reserve is required by the humphrey hawkins act to testify before congress twice each year to explain the fed s policy actions and to detail the fed s outlook for future economic develop ments similarly the reserve bank of new zealand is required under the reserve bank act of 1989 to publish policy statements that spell out its plans the january 1994 legislation governing the banque de france requires its gov ernor to appear before parliament and the european central bank must under the maastricht treaty report at least annually to the european parlia ment if public statements about policy intentions are not credible the question naturally arises as to why central banks are frequently required to make them the answer of course is that announcements do provide the public with some information given the growing interest in policy transparency particu larly among those central banks that have adopted some form of inflation targeting it is perhaps surprising that there has been relatively little explicit analysis of how inflation targeting requirements might combine with reporting requirements to influence the informational content of announcements the conduct of stabilization policies and the central bank s credibility the purpose of this paper is to analyse the way inflation targeting affects the incentives the central bank faces in announcing targets when the central bank has private information about the economy and the public is uncertain about the central bank s preferences inflation targeting has seen increased popularity in recent years but a fixed target for inflation is generally suboptimal in the face of supply shocks while state contingent targets are viewed as not feasible an important result of this paper is that allowing the central bank to announce its own inflation target

the fisher hypothesis a critique of recent results and some new evidence the fisher hypothesis 5 that nominal interest rates should respond point for point to changes in the expected inflation rate while theoretically appealing has had limited success in explaining actual interest rate movements most empirical work has shown that net after tax nominal interest rates are not as sensitive to changes in expected inflation as the hypothesis suggests they should be more troublesome still are the results of two recent studies carmichael and stebbing 3 4 hereafter cs and amsler 1 turn the fisher hypothesis on its head by demonstrating that net nominal yields on financial assets do not respond at all to changes in the expected inflation rate rather the net real yield on these assets falls point for point with increases in the expected inflation rate

the impact of surplus schooling on productivity and earnings this article examines the impact of surplus schooling on individual productivity and earnings it proposes a model that divides workers education into two components education that is required and thus fully utilized in the job and education that exceeds the amount required and thus may be underutilized in the job the model is tested with data from the 1969 1973 and 1977 quality of working life surveys quinn and staines 1979 required schooling for each occupation is derived from estimates by job incumbents and by the dictionary of occupational titles the results show thqt surplus or underutilized education is rewarded at a lower rate than required education with the actual return dependent on the type of job

job matching and job competition are lower educated workers at the back of job queues abstract during the cyclical downturn of the 1980s unemployment in the netherlands increased substantially with unemployment rates of lower educated workers increasing more than those of higher educated workers a possible explanation of this phenomenon is job competition between workers with different levels of education another explanation of the diverging unemployment rates is that employers dismiss replaceable lower educated workers before irreplaceable higher educated workers in this paper we scrutinize the job competition explanation our results show that there only is job competition between unemployed workers with an academic and a higher vocational education there is no job competition at lower levels of education

a nested ces approach to capital energy substitution abstract this paper uses the nested constant elasticity of substitution ces production function to estimate elasticities of substitution between capital labour energy and materials over the 1971 1976 period around the initial energy crisis elasticities are estimated for each of the two digit sic industries within us manufacturing using more disaggregate four digit sic data the nested ces function makes it possible to distinguish between engineering and economic elasticities of substitution capital and energy are estimated to be slight engineering substitutes and economic complements labour energy and materials are estimated economic substitutes

inflation risk taxes and the demand for owner occupied housing a bstract a portfolio choice model is formulated which focuses on the possibility of inflation hedging motives in housing demand in the 1970s an asset demand equation is used to estimate the capitalization of inflation expectations into house prices through tax mortgage and hedging effects the empirical results indicate that even after accounting for tax and mortgage effects the hedging motive was significant in bidding up house prices one implication is that the tax effects of inflation may have been overstated in previous research that ignored inflation risk

real interest rates anticipated inflation and unanticipated money a multi country study a bstractin this paper we examine real interest rate behavior in canada west germany the united states and the united kingdom using a model that yields a semi reduced form equation linking the real interest rate to monetary growth shocks anticipated inflation and expected inflation variance the estimator used in our analysis accommodates regressors from other regressions ensuring that accurate inferences are obtained in all countries we find that increases in anticipated inflation initially dampen real interest rates in addition a significant and negative relationship between unanticipated money shocks and real interest across all countries is discovered inflation variance typically exhibits little explanatory power

a theory of signalling during job search employment efficiency and stigmatised jobs this paper discusses why redundant skilled workers may be reluctant to accept interim unskilled jobs if skilled work is more satisfying or less arduous for highly productive workers then such workers invest more in moving quickly between skilled jobs thus high productivity workers tend to search on the job and if unemployed will specialise in job search rather than take an interim position if individual differences in productivity are known to the worker but not the potential employer then search strategy may be used as a productivity signal with more than the efficient proportion of workers searching on the job and too few accepting interim unskilled jobs optimal policy requires a subsidy on interim unskilled jobs

worker turnover at the firm level and crowding out of lower educated workers this paper investigates whether employers exploit cyclical downturns to improve the average skill level of their work force we use a unique dataset that contains information on workers jobs as well as firm characteristics our findings are that at each job level mainly lower educated workers leave during downturns furthermore at each level of job complexity workers with a higher education are not more productive than lower educated workers we find no evidence that higher educated workers crowd out lower educated workers during recessions

assessing the impact of interest rates in less developed countries abstract empirical results obtained do not unambiguously support what one should expect on the basis of conventional economic theory cross country evidence on the average relationship for 64 ldcs during the period 1971 1980 between some of the macroeconomic variables such as rate of growth of real gdp real financial assets saving income and investment income ratios and rate of return on investment on the one hand and the level of the real interest rate on the other is analyzed by applying a non parametric mann whitney test it is found that there is no difference with any statistical significance between the two groups of ldcs above and below the mean real interest rate this implies that the level of the real interest rate by itself has little or no impact on the selected macroeconomic variables

the postwar stability of the fisher effect most research concerning the fisher relationship has concentrated on the magnitude and significance of the response of nominal interest rates to anticipated inflation recently attention has shifted to the stability of that response according to previous estimates the impact of anticipated inflation on interest rates varies substantially over time by extending a standard model to include tax and aggregate supply shock effects we are able to reduce such instability considerably our results also reveal that increased foreign demand for bonds lowers the interest rate

a matching model with endogenous skill requirements we consider a labor market in which workers differ in their abilities and jobs differ in their skill requirements the distribution of worker abilities is exogenous but we model the choice of skill requirements by firms high skill jobs produce more output than low skill jobs but high skill jobs require high skill workers and thus are more difficult to fill we use a matching model together with a nash bargaining approach to wage setting to determine the equilibrium mix of job types along with the equilibrium relationship between worker and job characteristics wages and unemployment

the economics of financing higher education different arguments exist pro and contra tax financed subsidies in higher education it has been argued that private incentives to study are sufficiently high while the financing of those subsidies can be deemed regressive as they are co financed by relatively poorer non students alternatively several arguments have been put forward why higher tax financed subsidies are desirable such as externalities and credit constraints this study scrutinizes these different arguments and discusses the implications for the different ways in which higher education can be financed calculations of private returns across the oecd confirm that private incentives to invest in higher education are high however economic theory poses that it is the marginal social return that must guide policy which will reflect both equity and efficiency considerations we assess the potential regressivity of higher education subsidies using different perspectives and assess the different efficiency arguments for government intervention in higher education tax financed subsidies turn out to be regressive in most cases but depending on the perspective and the country under examination discussion of the efficiency arguments is focused on those that are most relevant in light of the empirical evidence and their relevance for the different financing modes externalities uninsurable risk credit constraints and misprediction we conclude that to deal with the more credible failures in higher education tax financed subsidies are blunt instruments for a large share of the countries under consideration shifting towards income contingent loans or graduate taxes appears more appropriate when taking into account both efficiency and equity considerations

cheap talk and the fed a theory of imprecise policy announcments this paper examines the problem faced by the federal reserve in announcing its private information about its future policies because it would like to manipulate expectations and pursue a time inconsistent policy the fed cannot reveal its policy objectives precisely and credibly it can however communicate some information about its goals through the cheap talk mechanism of vincent crawford and joel sobel making announcements that are imprecise and only giving ranges within which these goals may lie copyright 1989 by american economic association

monetary policy lessons of recent inflation and disinflation by 1975 most economists agreed that the money demand function in the united states was reasonably stable and could serve as a reliable basis for the formulation of monetary policy those suspicious of monetarism were on the defensive in the light of the apparently inexorable increase of m1 velocity of about three percent per year with deviations of only a few tenths of a percent experience with rising money growth and rising inflation through 1980 only confirmed monetarist views as figure 1 shows all this had changed by 1986 with disinflation in the 1980s m1 velocity departed convincingly from its 1953 79 trend the money demand function seems to have fallen apart and is apparently not a reliable basis for monetary policy after all consequently the first major section following this introduction is devoted to the decline of velocity after 1981 and the demise of the standard money demand function some authors including i believe benjamin friedman conclude that this evidence leaves us so uncertain about the nature of money demand that policymakers cannot rely at all on any presumed money demand regularities in contrast my working hypothesis is that the money demand continues to be a stable function of relatively few variables but that the interest elasticity of money demand is substantially higher than previously thought others have sought money demand explanations in terms of regime shifts but that literature will not be discussed here events have not been kind to keynesian monetary policy positions either keynesians tend to concentrate on interest rates especially real interest rates as the best guide to the effects of monetary policy on the economy the real rate is discussed

fisher s paradox and the theory of interest irving fisher s theory of interest has proved to be a most durable and influential contribution to economic theory a central element of fisher s contribution is the fisher hypothesis that over the longer term the real rate of interest is approximately constant being determined largely by time preference with movements in the nominal interest rate reflecting movements in the rate of inflation one for one the paradox of the fisher hypothesis is that despite its wide acceptance as the cornerstone of interest rate theory most empirical evidence appears to be inconsistent with the hypothesis at least in its strictest form this empirical anomaly was noted by fisher himself who attributed it to money illusion in the fifty years following the publication of the theory of interest a considerable literature has evolved around this paradox the unifying theme of this literature is a common acceptance of the essence of fisher s hypothesis most of the energy in this literature has been devoted to explaining systematic movements in the real rate of interest and to providing reasons why the relationship between the nominal interest rate and inflation may only be approximate in

on the characterisation of the world real interest rate this paper characterises the world real interest rate as a common trend in real interest rates in germany japan and the united states even if there is scepticism in the existence of the world real interest in theoretical terms real interest parity is based on the presumed validity of uncovered interest parity and purchasing power parity but the empirical evidence of these parity conditions is not strong and thus the presence of the world real interest rate the significance of this paper is therefore to visualise the current level of international economic integration by characterising the approximate world real interest rate as a single common trend taking full advantage of the fact that real interest rates in three large open economies have been moving together sharing a common component even if their levels are distinctively different this single common trend has desirable properties as the world real interest rate first it is a parsimonious and monotonically increasing function of the real interest rates in three large open economies that can be world price or interest rate maker in contrast with small open economies second it is moving together with national real interest rates one for one hence the deviations from the world rate are temporary because common trend represents the common driving force of national rates over the long run period third it can explain as high a proportion as possible of the variances of national rates

why real interest rates were so low in the 1970 s the economic turmoil of the 1970 s resulted in record postwar increases in inflation unemployment and nominal interest rates yet it was declines that were hardest to explain the average real value of a share of common stock plummeted productivity growth evaporated real interest rates measured as the spread between nominal interest rates and the inflation rate turned negative see table 1 over the past decade an explosion has occurred in the amount of attention paid to the relationship between nominal and thus real interest rates and expected inflation rates a good deal of this effort has been directed toward empirical analysis of the fisher neutrality hypothesis that nominal rates respond one for one with expected inflation rates most empirical tests of the fisher hypothesis have been bivariate interest rates were regressed on a constant and on actual or expected inflation measures estimates of the impact of inflation on interest rates in these and even in extended models are often significantly below one are often statistically imprecise and tend to be unstable over time the middle column of table i reflects this the coefficient of inflation on nominal interest rates there drops from 0 78 to 0 59 in the latter 1970 s another branch of work on nominal interest rates has concentrated on the institutional impediments to the fisher hypothesis robert mundell and james tobin demonstrate that nominal rates change by a smaller amount than the expected inflation rate does when a real balance effect exists and money pays no interest michael darby and martin feldstein on the other hand argue that nominal rates should exhibit a greater thanunity response to expected inflation due to the nature of u s income tax laws 2 here i estimate the relation between interest rates expected inflation and real forces such estimates are required for evaluating the effects of inflation on saving investment the distribution of income and the redistribution of wealth to generate estimates of the net impact of these various factors on interest rates and to avoid the identification and simultaneity problems masked but not often remedied by instrumental variables techniques i employ only exogenous regressors to buttress the argument i examine the individual links in the chain which are summarized in the reduced form the novel aspect of the model presented in section i is its addition of aggregate supply shocks to the determination of interest rates i trace the reduction in the supply of complementary factor inputs in the 1970 s to a decline in the demand for capital and therefore in real interest rates the inclusion of this supply force along with expected inflation allows one to distinguish between two offsetting effects on interest rates the depressing effect on real rates through lower investment demand and the elevating effect on nominal rates of higher expected inflation the results in section ii not only strongly support the economic and statistical importance of supply shocks on real interest rates but also resolve some longstanding interest rate puzzles allowing for the impact of factor supply produces a significant estimated response to expected inflation for a sample that ends prior to late 1960 s the magnitude assistant professor school of business administration university of california berkeley i would like to thank george akerlof robert j gordon robert a meyer joe peek janet yellen the members of the economic analysis and policy seminar at berkeley participants at the nber conference on inflation and financial markets and anonymous referees for helpful comments data resources supplied data and computational services financial support was provided by the berkeley program in finance and nsf grant ses8109093 linda pacheco supplied able research assistance errors of omission or commission are my responsibility see william gibson david pyle john carlson and thomas cargill and robert meyer 2maurice levi and john makin derive the reducedform effect of expected inflation on nominal interest rates as a function of the structural parameters

raw materials profits and the productivity slowdown a factor price frontier framework is used to clarify the analogy of an increase decrease in raw material prices with autonomous technological regress progress factor price profiles are estimated for the manufacturing sector of the united states the united kingdom germany and japan the production model in conjunction with estimates obtained from the factor price frontier attributes much of the slowdown in manufacturing productivity to the rise in relative raw material prices part of the apparent productivity riddle may have to do with the use of double deflated national accounting measures of value added which have an inherent measurement bias

more flexible use of survey data on expectations in macroeconomic models a flexible procedure is proposed whereby both the random and systematic errors in measurement of survey data on inflation expectations can be appropriately handled when these surveys are used in the estimation of macroeconomic models during the period 1952 1980 livingston s two expectations series and the src series systematically underestimated inflation expectations by nearly 25 the asa nber survey however does not exhibit such underestimation thus the use of the livingston or src data as an unbiased measure of the true expectations of inflation would result in overestimation of the fisher effect and the ex ante real interest rate

government borrowing and tax adjusted real and nominal interest rates the purpose of this paper is to test for the effect of federal government budget deficits on one year tax adjusted nominal and real interest rates in an is lm as model the results suggest that the specification of the dependent variable is a crucial issue in the debate over the linkage between deficits and interest rates the evidence shows a positive and significant effect of various measures of the federal government deficit and debt on the real tax adjusted treasury bill rate in both the levels and the first differenced equations but not on the nominal tax adjusted rate the positive and significant deficit debt coefficients are also confirmed when the first differenced equation is estimated by instrumental variables and when the equation is estimated over various time periods thus there is robust evidence of a positive linkage between federal government borrowing and the tax adjusted real but not nominal interest rates

on the job search in a matching model with heterogeneous jobs and workers this paper considers a matching model with heterogenous jobs unskilled and skilled and workers low and high educated which allows for on the job search by mismatched workers the latter are high educated workers who transitorily accept unskilled jobs and continue to search for skilled jobs our findings show that on the job search introduces an additional source of between and within group wage inequality furthermore the higher quit rate of mismatched workers exerts a negative externality on unskilled jobs and weakens the labour market position of low educated workers this last feature changes the effects of skill biased technological change and it alters the response of the labour market to shifts in the skill distribution this paper has been written for presentation as an invited lecture at the annual conference of the european association of labour economics eale 2003 seville 18 21 september 2003 we are very grateful to maite blazquez for excellent research assistance we also wish to thank barbara petrongolo participants in seminars at uc3m core essex and lse for helpful comments and especially j albrecht for his insightful discussion on a preliminary draft of this paper the usual disclaimer applies

central banker contracts incomplete information and monetary policy surprises in search of a selfish central banker approaching monetary policy as a principal agent problemprovides a useful framework for interpreting alternativedelegation schemes in this paper we consider theeffectiveness of central banker incentive schemes when theprincipal delegates monetary policy through contracts butremains uncertain about the central banker s responsiveness tosuch schemes we adopt a simple principal agent model andassume that the central banker s trade off between socialwelfare and the incentive scheme is private information weconsider two types of central bankers one who responds to theincentive scheme selfish and one who does not and onlycares about social welfare benevolent we demonstratethat when a benevolent central banker accepts a contractdesigned for a selfish central banker positive inflationsurprises occur and output exceeds its natural rate wefurther show that a benevolent central banker with aninflation bias has an incentive to masquerade as selfish mechanisms exist that solve that problem by achievingpreference revelation we consider a simple mechanism indominant strategies that induces the benevolent type eithernot to breach or not to accept the appointment contract inthe first place this multi period mechanism works with eitherinflation targets or the appointment of a conservativecentral banker our results suggest that more complicatedincentive schemes embedded within broader constitutionalarrangements are required in the presence of privateinformation for them to work effectively

international expected real interest rates new tests of the parity hypothesis and u s fiscal policy effects abstract this paper investigates the links among expected real interest rates across countries and also those between international expected real interest rates and u s fiscal policy we analyze the cross sectional mean of international ex post real interest rates as an estimator for the mean international expected real interest rate our results strongly reject the international expected real interest rate parity hypothesis reveal that u s budget deficits have no independent effects on international real rates given the impact of u s government defense spending and suggest that forces other than u s fiscal policy account for the post 1980 rise in international real rates

the adjustment of the real interest rate to inflation this paper reports tests of carmichael and stebbing s 1983 inverted fisher hypothesis that it is the real rather than the nominal interest rate which adjusts to changes in the expected inflation rate unlike the earlier analysis the results presented here are based on a properly specified estimating equation derived from a short run open economy macro model the results support the inverted fisher hypothesis in the short run but indicate that there is some overshooting of the real interest rate so that after four quarters about 75 of the effect of an expected inflation change is reflected in real rates while the remainder leads to an increase in the nominal rate

the reaction of stock returns to anticipated and unanticipated changes in money a re examination of the evidence in the frequency domain the relationship between money and stock returns is analysed for the 1977 1985 period spectral analysis and a var vector autoregressive model are used in the analysis the preliminary results suggest a positive relationship between stock returns and money supply along a business cycles and high frequency cycles a detailed analysis however suggests the spurious character of this observed relationship the money stock returns relationship over business cycles can be explained by a contemporaneous adjustment of stock returns and anticipated money in response to business cycle anticipations the high frequency relationship on the other hand can be related to contemporaneous adjustment of stock returns and money anticipations in response to expected inflation in a framework characterized by the anticipation of the federal reserve reaction function the empirical results strongly suggest that both stock returns and money anticipations are determined in a forward looking manner incorporating the informat

the effect of federal deficits and debt on the tax adjusted short term real interest rate the stock versus flow effect of the federal debt deficit on a real interest rate is examined in a reduced form equation the evidence shows a positive and significant linkage between the federal debt and an ex post tax adjusted short term real interest rate

expectations surprises and treasury bill rates 1960 82 changes in six month bill rates over semiannual periods in the 1960s and 1970s are successfully related to expected changes and to surprises the latter include unanticipated changes in expected inflation in the growth of industrial production and base money and in inflation uncertainty estimation of the basic equation through the middle of 1983 does not suggest any change in structure moreover the equation explains 60 percent of the extraordinarily high level of real rates since late 1980 largely owing to an excess of unexpected net increases in anticipated inflation over actual increases our estimates provide some support for the expectations theory there appears to be information content in six month forward rates while this content is swamped by the impact of surprises in equations explaining rate changes in terms of forward rates alone the content is clear when proxies for the surprises are included in the equations the height and volatility of interest rates in the early 1980s spectacularly exceeded that of the past half century various researchers have attributed this to the sharp increase and decline in inflation the special characteristics of recent monetary the monetarist experiment and fiscal the structural deficit policies and mysterious or unidentified forces see clarida and friedman 1982 and makin and tanzi 1983 the present paper estimates the relationship between the six month treasury bill rate and its determinants in the 1960s and 1970s the purpose is to test various hypotheses regarding interest rate determination and to determine whether this relationship was altered markedly in the early 1980s the short term bill rate is chosen for investigation for two reasons first the yield on a short term instrument is independent of longer term expectations regarding inflation output growth and fiscal and monetary policies longerterm yields should depend heavily on such variables while reasonably accurate measures of expectations over say a six month horizon can probably be deduced are in fact available from survey data longer term expectations are both more uncertain and vary more widely across market participants second analysis of a short term bill rate allows an easy test of the expectations theory of interest rates recent studies by shiller campbell and schoenholtz 1983 and by mankiw and summers 1983 suggest that observed interest rate movements are unrelated to expected changes in rates extracted from the term structure of short term rates calling into question the validity of the expectations theory but see fama 1983 for an alternative view the six month bill rate is analyzed because it meshes best with the livingston survey data

money growth volatility and the macroeconomy this study analyzes the effects of variability in money growth on the macroeconomy for the period 1961 1 1984 4 within the context of a vector autoregressive model that contains variables typically included in a small macro model variance decompositions and historical decompositions are used to assess the impact of money growth variability the variance decompositions suggest substantial effects of money growth variability on the long term interest rate output and the price level historical decompositions for 1979 4 1984 4 suggest substantial effects of money growth variability on the interest rate and output but smaller effects on the price level are found copyright 1988 by ohio state university press
