monetary policy and liquid government debt abstract we examine the conduct of monetary policy in a world where the supply of outside money is controlled by the fiscal authority a scenario increasingly relevant for many developed economies today central bank control over the long run inflation rate depends on whether fiscal policy is ricardian or non ricardian the optimal monetary policy follows a generalized friedman rule that eliminates the liquidity premium on scarce treasury debt we derive conditions for determinacy under both fiscal regimes and show that they do not necessarily correspond to the taylor principle in addition non ricardian regimes may suffer from multiplicity of steady states when the government runs persistent deficits

interpreting instrumental variables estimates of the returns to schooling this article synthesizes economic insights from theoretical models of schooling choice based on individual benefits and econometric work interpreting instrumental variables estimates as weighted averages of individual specific causal effects linkages are illustrated using college proximity to instrument for schooling after characterizing groups differentially affected by the instrument according to family background i directly compute weights underlying estimation of the overall return in analyzing the level of schooling at which individuals change their behavior in response to the instrument i demonstrate that this instrument has its greatest impact on the transition from high school to college specification robustness is also examined

labor market returns to two and four year college the paper examines labor market returns to a two and four year college education analysis of the 1972 national longitudinal survey of youth observation that the average person who attended a two year college earned about 10 percent more than those without any college education comparison with the wages of those who attended a four year college education

sheepskin effects in the returns to education some previous discussions have dismissed screening theories of education partly on the ground that diploma years of education do not confer especially large earnings gains similarly most empirical research on earnings functions has assumed an absence of sheepskin effects we report evidence however of substantial and statistically significant sheepskin effects although this suggests that the previous dismissals of the screening hypothesis were premature our evidence of sheepskin effects is amenable to nonscreening interpretations also according to screening theories of education individuals with more schooling tend to earn more not because or at least not solely because schooling makes them more productive but rather because it credentiates them as more productive a frequently cited article by layard and psacharopoulos 1974 however dismissed the importance of the screening hypothesis on the grounds that several of its refutable predictions were not supported by available evidence one of these was the sheepskin prediction that wages will rise faster with extra years of education when the extra year also conveys a certificate after surveying a number of studies layard and psacharopoulous henceforth lp concluded that rates of return to dropouts are as high as to those who complete a course which refutes the sheepskin version of the screening hypothesis since publication of the lp paper an undergraduate labor economics textbook has cited lp s analysis of sheepskin effects as telling criticism of the screening hypothesis a prominent proponent of the screening hypothesis riley 1979 has accepted lp s summary of the empirical evidence but responded that some versions of the screening hypothesis do not imply sheepskin effects in the meantime the ongoing flood of empirical research on earnings functions typically has continued to treat the natural logarithm of the wage rate as a linear or occasionally quadratic function of years of education with no allowance for discontinuities in diploma years 2 the estimated rates of return used by lp were based on data that did not disaggregate dropouts earnings by how many years of school they had completed lp acknowledged we would have preferred to show the earnings gain associated with each year of the course including the year when it was successfully completed this note presents a reanalysis of sheepskin effects based on the type of data lp wished they had the results contain very strong evidence of sheepskin effects after all the next section describes our analysis and the following section summarizes and discusses our

euler equations and money market interest rates a challenge for monetary policy models standard macroeconomic models equate the money market rate targeted by the central bank with the interest rate implied by a consumption euler equation we use u s data to calculate the interest rates implied by euler equations derived from a number of specifications of household preferences correlations between these euler equation rates and the federal funds rate are generally negative regression results and impulse response functions imply that the spreads between the euler equation rates and the federal funds rate are systematically linked to the stance of monetary policy our findings pose a fundamental challenge for models that equate the two

the quality of schooling quantity alone is misleading although much research discusses the quantity of schooling as an effective impact on productivity and earnings most such research leaves out the idea of the quality of schooling which may cause biases in the estimated returns to schooling this paper consequently attempts to extend the standard mincerian approach to incorporate school quality as well as quantity it demonstrates how exclusion of quality in the standard procedure may cause biases in the estimated returns to years of schooling probably in the upward direction the paper explores the implications of this extension of the standard model for the case of young brazilian males it shows that the estimate of the private return to years of schooling using the preferred quality inclusive specification is only one half the estimate using the standard procedure indicating substantial upward bias in the standard estimates it further outlines a method for estimating a social return to quality and finds that it exceeds substantially the social return to quantity the paper then shows why this in turn suggests there may be an equity productivity trade off in schooling investments

fighting inflation with high interest rates the small open economy case under flexible prices in high inflation countries policymakers often end up paying interest on part of the money supply higher interest rates on money have been used both to reduce inflation and to defend the domestic currency this paper analyzes the effectiveness of such a policy in the context of an open economy with flexible prices and exchange rates a temporary increase in the interest rate on money reduces the price level on impact but inflation follows an explosive path afterwards the domestic currency appreciates on impact but begins to depreciate immediately thereafter hence the analysis does not support the use of high interest rates in disinflationary programs copyright 1995 by ohio state university press

monetary aggregates and liquidity in a neo wicksellian framework woodford 2003 describes a popular class of neo wicksellian models in which monetary policy is characterized by an interest rate rule and the money market and financial institutions are typically not even modeled critics contend that these models are incomplete and unsuitable for monetary policy evaluation our banks and bonds model starts with a standard neo wicksellian model and then adds banks and a role for bonds in the liquidity management of households and banks the banks and bonds model gives a more complete description of the economy but the neo wicksellian model has the virtue of simplicity our purpose here is to see if the neo wicksellian model gives a reasonably accurate account of macroeconomic behavior in the more complete banks and bonds model we do this by comparing the models second moments variance decompositions and impulse response functions we also study the role of monetary aggregates in predicting inflation in the two models

the fiscal theory of the price level in a world of low interest rates abstract a central equation for the fiscal theory of the price level ftpl is the government budget constraint or government valuation equation which equates the real value of government debt to the present value of fiscal surpluses in the past decade the governments of most developed economies have paid very low interest rates and there are many other periods in the past in which this has been the case in this paper we revisit the implications of the ftpl in a world where the rate of return on government debt may be below the growth rate of the economy considering different sources for the low returns dynamic inefficiency the liquidity premium of government debt or its favorable risk profile this article is part of a special issue entitled fiscal and monetary policies

monetary and fiscal policy interactions in a new keynesian model with capital accumulation and non ricardian consumers the paper examines simple monetary and fiscal policy rules consistent with determinate equilibrium dynamics in the absence of ricardian equivalence under this assumption government debt turns into a relevant state variable which needs to be accounted for in the analysis of equilibrium dynamics the key analytical finding is that without explicit reference to the level of government debt it is not possible to infer how strongly the monetary and fiscal instruments should be used to ensure determinate equilibrium dynamics specifically we identify bifurcations associated with threshold values of steady state debt leading to qualitative changes in the local determinacy requirements

fiscal requirements for dynamic and real determinacies in economies with private provision of liquidity a monetarist assessment we study the impact of fiscal policies on the inherent links between inflation unemployment and asset prices in an environment where firms provide liquidity and the central bank follows a constant money growth rate rule firms other than hiring workers also supply private assets that are not only useful as a store of value but also as collateral when firms are not taxed and public debt is scarce the economy is non ricardian so that real indeterminacies can be observed moreover labor market characteristics do not affect the demand for government liabilities however when agents face public and private asset scarcity labor market conditions then impact asset prices and inflation we further show that irrespective of the type of asset scarcity agents face when firms are taxed non ad valorem not only the level of tax revenues but also its composition matter for real allocations moreover we show that labor market conditions directly affect the dynamics of all government liabilities and inflation

timing and real indeterminacy in monetary models an increasingly common approach to the theoretical analysis of monetary policy is to ensure that a proposed policy does not introduce real indeterminacy and thus sunspot fluctuations into the model economy policy is typically conducted in terms of directives for the nominal interest rate this paper uses a discrete time money in the utility function model to demonstrate how seemingly minor modifications in the trading environment result in dramatic differences in the policy restrictions needed to ensure real determinacy these differences arise because of the differing pricing equations for the nominal interest rate

the role of liquid government bonds in the great transformation of american monetary policy abstract a fundamental shift in monetary policy occurred around 1980 the fed went from a passive policy to an active policy we study a model in which government bonds provide transactions services we present two calibrations of our model using pre and post 1980 data we show that estimates of pre and post 1980 policy rules all lie within our determinacy regions but the pre 1980 policy was a very bad monetary policy even if it avoided sunspot equilibria model simulations suggest that household welfare would have increased by 3 3 percent of permanent consumption in this period under an active policy

family background and the estimated return to schooling earnings regressions for married and cohabiting swedish males in 1993 indicate that controlling for family background reduces the measured return to education by about 9 percent net of measurement error bias the swedish evidence is generally consistent with the hypothesis that family background effects are primarily a result of an efficient marital sorting

the effects of family characteristics on the return to education in this paper the authors examine the role of parental education in the human capital production function by estimating the effects of parental education on the education profile of wages the analysis uses sibling pairs from the panel study of income dynamics and the national longitudinal surveys of labor market experience of young men and young women the authors obtained mixed evidence on whether parental education raises the return to education copyright 1996 by mit press

tobin s imperfect asset substitution in optimizing general equilibrium in this paper we present a dynamic optimizing model that allows explicitly for imperfect substitutability between different financial assets this is specified in a manner which captures tobin s 1969 view that an expansion of one asset s supply affects both the yield on that asset and the spread or risk premium between returns on that asset and alternative assets our estimates of this model on u s data confirm that some of the observed deviations of long term rates from the expectations theory of the term structure can be traced to movements in the relative stocks of financial assets the richer aggregate demand and asset specifications imply that there exists an additional channel of monetary policy our results suggest that central bank operations exercise a modest influence on the relative prices of alternative financial securities and so exert an extra effect on long term yields and aggregate demand separate from their effect on the expected path of short term rates

price level determinacy with an interest rate policy rule and rational expectations abstract this paper reconsiders a result obtained by sargent and wallace namely that price level indeterminacy obtains in their model if the monetary authorities adopt a feedback rule for the interest rate rather than the money stock it is shown that the indeterminacy vanishes if the interest rate rule is chosen so as to have a desired effect on the expected quantity of money demanded this holds even if considerable weight is given in the choice of a rule to the aim of smoothing interest rate fluctuations

a human capital model of the effects of ability and family background on optimal schooling levels this paper develops a theoretical model of optimal schooling levels where ability and family background are the central explanatory variables we derive schooling demand and supply functions based on individual wealth maximization using nlsy79 data we stratify our sample into one year fte work experience cohorts for 1985 1989 mincer s 1974 overtaking cohort the years of work experience at which individuals observed earnings approximately equal what they would have been based on schooling and ability alone corresponds to 13 fte years of work experience yielding on average a rate of return of 9 6 percent and an average optimal 11 4 years of schooling

a monetary explanation of the equity premium term premium and risk free rate puzzles this paper develops and estimates a monetary model that offers an explanation of some puzzling features of observed returns on equities and default free bonds the key feature of the model is that some assets other than money play a special role in facilitating transactions which affects the rate of return that they offer the model is capable of producing a low risk free rate a high equity premium and an average positive relationship between maturity and term premium for default free bonds the model s implications for the joint distribution of asset returns velocity inflation money growth and consumption growth are also compared to the behavior of these variables in the u s economy

returns to schooling implicit discount rates and black white wage differentials a simple econometric model of investment in schooling is developed and estimated the measure of individual discount rates implicit in their educational investment decisions suggests no difference between individuals from different socioeconomic backgrounds differences in individual speeds of educational attainment which do vary with background explain most of the variation in levels of attainment that is attributable to family background

distortionary taxation debt and the price level this paper considers the nominal and real determinacy of equilibria under an exogenously specifi ed path of interest rates in an economy in which taxation is either lump sum or distortionary under lump sum taxation we confirm the well known finding that equilibria display nominal in determinacy if the primary surplus is exogenous endogenous under distortionary taxation this classification is no longer relevant nominal determinacy is always ensured since distortionary taxes establish a link between the allocation and the sequences of taxes and debt and hence the price level regardless of whether the primary surplus is exogenous or endogenous distortionary taxation however increases the scope for real indeterminacy as a general feature the real in determinacy of equilibria depends on the interaction of fiscal and monetary policies i e on the sequences of taxes debt and interest rates if for example fiscal policy runs a balanced budget the central bank should set the nominal interest rate in a way consistent with long run deflation in order to ensure real determinacy this finding is different from a balanced budget policy under lump sum taxes where no such qualification with respect to the interest rate needs to be made

liquidity premiums on government debt and the fiscal theory of the price level we construct a dynamic general equilibrium model where agents use nominal government bonds as collateral in secured lending arrangements if the collateral constraint binds agents price in a liquidity premium on bonds that lowers the real rate on bonds in equilibrium the price level is determined according to the fiscal theory of the price level however the market value of government debt exceeds its fundamental value we then examine the dynamic properties of the model and show that the market value of the government debt can fluctuate even though there are no changes to current or future taxes or spending the price dynamics are driven solely by the liquidity premium on the debt

empirical age earnings profiles the human capital earnings function in which earnings are expressed as a quadratic in potential experience is probably the most widely accepted empirical specification in economics in spite of its widespread acceptance the human capital earnings function provides a very poor approximation of the true empirical relationship between earnings and experience the standard formulation understates early career earnings growth by about 30 50 and overstates midcareer growth by 20 50 however simple alternative specifications that fit the data are available

life cycle schooling and dynamic selection bias models and evidence for five cohorts of american males this paper examines an empirical regularity found in many societies that family influences on the probability of transiting from one grade level to the next diminish at higher levels of education we examine the statistical model used to establish the empirical regularity and the intuitive behavioral interpretation often used to rationalize it we show that the implicit economic model assumes myopia the intuitive interpretive model is identified only by imposing arbitrary distributional assumptions onto the data we produce an alternative choice theoretic model with fewer parameters that rationalizes the same data and is not based on arbitrary distributional assumptions

a simplified exposition of smooth pasting abstract the decision on when to make an irreversible investment is considered as a trade off between the instantaneous size of the net benefit and the time at which it is obtained the benefit can be larger by waiting longer but then it will also have to be more discounted smooth pasting arises as a first order condition for maximum expected profit the relationship to the standard approach is illustrated by a geometric brownian price process

the information content of the interest rate and optimal monetary policy optimal monetary policy rules are derived in a rational expectations cum contracting framework monetary policy is redundant if wage setters exploit the incomplete current information embodied in today s nominal interest rate however the monetary authorities can save wage setters the costs of indexing to the interest rate a contemporaneous money supply feedback rule is as effective as wage indexation a lagged rule relevant under a regime of money supply targeting is also as effective if investors use the interest rate both rules have the same implications for the real interest rate as poole s combination policy however the two rules have strikingly different implications for the nominal interest rate

interactions of monetary and fiscal policy via open market operations we examine interactions of monetary and fiscal policy in a sticky price model where public debt is non neutral as it provides transaction services this property is brought about by a legal restriction on open market operations by which only government bonds are eligible debt creation eases access to money and can therefore induce households to increase purchases of goods government expenditures which are not completely tax financed and deficit financed tax cuts then tend to stimulate private consumption however for these fiscal impulses to raise real activity monetary policy should not too aggressively aim at stabilising the economy

debt nonneutrality policy interactions and macroeconomic stability we study the consequences of non neutrality of government debt for macroeconomic stabilization policy in an environment where prices are sticky assuming transaction services of government bonds ricardian equivalence fails because public debt has a negative impact on its marginal rate of return and thus on private savings stability of equilibrium sequences requires a stationary evolution of real public debt which steers inflation expectations and rules out endogenous fluctuations under anti inflationary monetary policy regimes macroeconomic fluctuations tend to decrease with the share of tax financing which justifies tight debt constraints in particular a balanced budget policy stabilizes the economy under cost push shocks such that output and inflation variances can be lower than in a corresponding case where debt is neutral

interest rate rules and price determinacy the role of transactions services of bonds abstract interest rate rules have been associated with price indeterminacy when they do not respond aggressively enough to inflation price indeterminacy is typically associated with indeterminacy of real bond balances suggesting that the missing element is a meaningful role for government bonds we assume that government bonds provide arbitrarily small transactions services and show that this can dramatically change the local and global determinacy conditions in particular the specification of fiscal policy affects the aggressiveness with which monetary policy must respond to inflation to deliver local determinacy a range of passive monetary policies even an interest rate peg may yield determinacy

monetary and fiscal policy interaction the current consensus assignment in the light of recent developments in the last few years papers have begun to analyse optimal monetary and fiscal policy in models incorporating nominal rigidities where social welfare is derived from the utility of agents this article examines whether this analysis provides support for the consensus assignment where monetary policy controls demand and inflation and fiscal policy controls government debt we argue that the basic structure of new keynesian models implies that monetary policy dominates fiscal policy as a means of controlling inflation no similar dominance appears to operate for fiscal policy and debt if debt has to return to its initial level after shocks

the indeterminacy of prices under interest rate pegging the non ricardian case abstract this paper investigates the issue of price level indeterminacy under a pure interest rate peg in models that depart from standard ricardian assumptions using a monetary version of blanchard s finite horizons model i find wealth effects operating on government bonds are not sufficient to determine a unique price level next i consider price determination under a non ricardian fiscal authority i show that if agents rationally perceive the possibility of fiscal default the price level is again indeterminate i conclude that departures from ricardian equivalence are not sufficient to ensure a unique price level under a monetary policy of pure interest rate pegging
