longevity risk subjective survival expectations and individual saving behavior abstract we provide evidence of individuals awareness of longevity risk the uncertainty about future survival probabilities based on subjective survival expectations elicited in the survey of health ageing and retirement in europe share and matching data on longevity risk from the human mortality database we find a positive relationship between the forecast dispersion in subjective survival estimates and longevity risk which indicates that individuals are to some extent aware of longevity risk our analysis of savings behavior shows that the dispersion in survival estimates is primarily explained by individuals disagreeing on the survival probability and not by their true awareness of the underlying uncertainty individuals do not save more on average when faced with longevity risk although theory suggests they should

optimal price and inventory adjustment in an open economy model of the business cycle this paper presents a macroeconomic model containing optimizing inventory holding firms that is consistent with a number of prominent empirical regularities concerning fluctuations in output exchange rates relative prices and money prices are sticky but they are not predetermined still our model is consistent with exchange rate overshooting in the sense of dornbusch typical sticky price models allow a divergence between current production and current demand but this divergence is never allowed to feed back into the model our optimal inventory adjustments reconcile divergences between current demand and production and the inventory stock movements provide expected future dynamics

sluggish price adjustments and the link between money and price the simple quantity theory of money asserts that because the velocity of money and fullemployment output are constants if the money supply doubles the price level must also double 15 this view of the quantity theory of money is also supported by the policy ineffectiveness proposition put forward by lucas 16 sargent and wallace 20 and barro 1 the policy ineffectiveness proposition asserts that real variables like output and unemployment respond only to unanticipated movements in the money supply but do not respond to anticipated money supply associated with the systematic feedback rules one of the premises essential to the validity of this proposition is the perfect flexibility of prices the corollary of the policy ineffectiveness proposition as expounded by gordon 12 in invalidating this propositin is that because output does not respond to anticipated money supply changes and remains at the natural level the price level responds contemporaneously and proportionately to the anticipated changes in the money supply this conclusion is also consistent with barro s hypothesis that perceived movements in the money stock imply equiproportionate contemporaneous movements in the price level 3 565 66 this one to one relationship between the anticipated money supply and the price level has also been shown theoretically by barro 1 and hercowitz 13 it is this conclusion that needs to be tested by accounting for the speed of adjustments of prices the purpose of this study is to explore theoretically and empirically the link between money supply and price levels by incorporating a gradual price adjustment mechanism more specifically this study examines a the one to one relationship between the log of current money stock and the log of the price level purported by barro 3 b effects of unanticipated money growth on the aggregate price and c importance of anticipated money growth in determining the price level given the current money stock and the current and lagged values of the unanticipated money growth the key element of the study is the realization that the economy is comprised of markets with differing degrees of price adjustments numerous cases of price stickiness can be identified in modern economies as enumerated in survey work by blinder 4 also for instance devadoss and choi 6 observe that the u s agricultural program s price fixing policies such as price

competing macro hypotheses in the united states a kalman filtering approach the empirical validity of alternative views about the short run determinants of real output growth in the united states is investigated a nested framework is used to test the macro rational expectations mre hypothesis directly against two competing hypotheses the neo keynesian view that anticipated and unanticpated monetary policy both matter and friedman s 1977 proposition that increased inflation uncertainty reduces real output at least temporarily the unobservable explanatory variables are obtained from time varying parameter models of inflation and money growth which generate forecast errors and their conditional variances consistent with rational expectations under a continuously chaning policy regime the empirical results strongly support friedman s view the mre hypothesis must be rejected since both anticipated and unanticipated monetary changes matter the results prove robust across different model specifications and estimation techniques

an examination of aggregate price uncertainty in four countries and someimplications for real output this stu dy constructs measures of aggregate price uncertainty for four countries canada west germany great britain and the united states and examines the relationship across countries and through time between the inflation rate inflation variability and measures of price uncertainty the results suggest that the higher and more variable inflation of the 1970s increased uncertainty about the aggregate price level in canada great britain and the united states but not west ge rmany and there was a significant negative output effect of aggregate price uncertainty for canada and the united kingdom but not for the united states or west germany copyright 1987 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

empirical measures of inflation uncertainty a cautionary note a direct ex ante measure of inflation uncertainty in the us is compared with a number of proxies used in empirical studies the direct estimate is the root mean subjective variance of the probability distributions for inflation reported by respondents to the asa nber survey the proxies include forecast standard deviations from arima arch and structural models of inflation these proxies are not significantly correlated with the direct measure nor with one another use of the proxies leads to incorrect inferences about the correlation between inflation and inflation uncertainty and between inflation uncertainty and the real interest rate

enterprise diversification in us dairy impact of risk preferences on scale and scope economies enterprise diversification has recently become a prominent feature of us dairy farms scope economies and risk aversion are two forces that simultaneously determine diversification we jointly estimate scope economies and determine risk preferences under price uncertainty we reject risk neutrality in favour of increasing absolute risk aversion iara and increasing relative risk aversion irra scope economies are significant but diminish with farm size increasing returns to scale exist in the production of multiple enterprises and diminish with size large farms operate under decreasing returns to scale ignoring risk preferences a common practice in empirical work results in an underestimate of the effect of scope economies for large farms

price inertia money supply and price changes price stickiness is incorporated in the partial information localizedmarket framework of rational expectation models to show that the money stock has less than an equiproportionate effect on the aggregate price and that the unanticipated monetary policy component has differing impacts on prices at the market level the empirical analysis involves estimation of generated regressor models of money forecasting and price equations using the computationally intensive parametric bootstrap method developed most recently by smith and mcaleer the results are unfavourable to the hypothesis of a one to one relationship between current money stock and prices rather they lend distinct support to conclusions of a sluggish price adjustment model that money stock has less than equiproportionate effect on prices empirical results also show that the effects of unanticipated money growth on prices vary across markets

unanticipated monetary growth output and the price level in latin america an empirical investigation abstract this paper provides statistical evidence on the response of real output and the price level to movements in unanticipated monetary growth for 16 latin american countries in the context of barro s version of the rational expectations natural rate theory arima p d q modeling of the growth rate of m2 is employed for each country and the residuals of the selected model utilized to estimate the parameters of the real output and price level equations careful attention is devoted to the autocorrelation structure of the residuals of the real output and price level equations the empirical results suggest that generally unanticipated monetary growth has positive effects on real output and negative effects on the price level such patterns however do not exhibit an unambiguous symmetric response

source of monetary growth uncertainty and economic activity the time varying parameter model a large body of research suggests that uncertainty is an important factor affecting economic activity most earlier research however fails to consider the possibility that uncertainty may affect the value of new information and economic activity differently depending upon its source the author first examines the importance of these different sources for modeling u s monetary growth uncertainty he then empirically relates different sources of monetary growth uncertainty to economic activity measured by real gnp the results suggest that different sources of uncertainty have different impacts on economic activity the results tend to confirm predictions arising in the literature on irreversible investment and uncertainty copyright 1993 by mit press

the time varying parameter model for modeling changing conditional variance the case of the lucas hypothesis the main econometric issue in testing the lucas 1973 hypothesis in a time series context is estimation of the forecast error variance conditional on past information the conditional variance may vary through time as monetary policy evolves and agents are obliged to infer its present state under the assumption that a monetary policy regime is continuously changing a time varying parameter model is proposed for the monetary growth function based on kalman filtering estimation of recursive forecast errors and their conditional variances the lucas hypothesis is tested for the u s economy 1964 1 1985 4 using monetary growth as aggregate demand variable the lucas hypothesis is rejected in favor of friedman s 1977 hypothesis the conditional variance of monetary growth affects real output directly not through the coefficients on the forecast error term in the lucas type output equation

introducing new futures contracts reinforcement versus cannibalism abstract in order to assure survival futures exchanges around the world are in constant search of new futures contracts that will generate a profitable level of trading volume introducing new futures contracts may increase or decrease the volume for those contracts already listed using a multi product hedging model in which the perspective has been shifted from portfolio to exchange management we study these effects using data from two exchanges that differ regarding assets traded and market liquidity amsterdam exchanges versus chicago board of trade we show the usefulness of the proposed method the method may also be used to evaluate the benefits for exchanges that plan to internationalize their activities by merging with another exchange or by cross listing other exchanges futures contracts

offshore commodity hedging under floating exchange rates exchange rate uncertainty can have significant effects on the optimal hedging behavior of offshore commodity traders in this paper the standard commodity hedging framework is extended first to incorporate exchange rate uncertainty and second to forward cover transactions in the foreign exchange market the implications of exchange rate movements and forward cover decisions for offshore commodity hedgers are illustrated using data relevant to hedging australian export wheat on the chicago board of trade

financial market efficiency the decomposition of anticipated versus unanticipated money growth and further tests of the relation between money and real output note probably the most controversial empirical findings in macroeconomics in the last decade stem from robert barro s investigations into the relative effects of unanticipated versus anticipated money growth on unemployment and real output these studies generally proceed by decomposing observed money growth into what is defined to be its anticipated and unanticipated components and then test the restriction that only the unanticipated money measure has important effects for unemployment and real output in black box reduced form real side equations that include determinants of the natural rates of unemployment and real output as additional explanatory variables l the results of these tests for the annual postwar u s data generally cannot reject the hypothesis that only unanticipated money growth is important for the determination of aggregate real activity 2 anticipated money growth is found to be neutral for unemployment and real output these results are important because they give empirical support to the assertion that the apparent nonneutrality of observed money growth does not provide any firm basis for the efficacy of a systematic countercyclical monetary policy it should be clear that a crucial problem in testing for the neutrality nonneutrality of anticipated unanticipated money growth lies in developing an appropriate decomposition of observed money growth into its anticipated and unanticipated parts small 13 mishkin 8 and weintraub 14 among others have

monetary policy and inflation uncertainty in the united states and germany friedman s 16 proposition that increased inflation uncertainty may adversely affect real economic variables has received much attention over the last decade the theoretical arguments for such real effects are compelling however the empirical evidence on their presence and magnitude in different countries is mixed most results for the postwar u s economy strongly support the proposition 28 25 26 19 24 7 whereas it is generally rejected for the german economy 23 17 8 2 while a direct comparison of the u s and german results is difficult due to a lack of uniform sample periods data definitions estimation techniques and or measures of inflation uncertainty the evidence to date nevertheless suggests that the role of inflation uncertainty differs sharply between the two countries the question then arises what factor s can explain the difference one popular explanation is that the monetary authorities in the united states and germany respond quite differently to accelerating inflation 3 so that the behavior of uncertainty differs across countries 4 the u s federal reserve is often criticized for switching frequently between the primary policy goals of price stability and full employment possibly due to political pressures 21 30 since inflation is primarily a monetary phenomenon in the long run it is likely that such stop and go policies increase the uncertainty about future steady state inflation which in turn can adversely affect real output growth by reducing overall economic efficiency the german bundesbank on the other hand is reputed for its staunch and credible commitment to price stability which often takes precedence over other policy goals a more consistent and predictable

unemployment and female labour supply the definition of labour force participation in the standard labour supply model stands in sharp contrast to that used in compiling the labour force statistics in the labour supply models only those supplying positive hours of work are considered to be labour force participants on the other hand participation in the labour force statistics is often defined to include not only those supplying positive hours but also those actively searching for work this paper is an attempt to reconcile these concepts by allowing unemployed workers to enter a generalisation of the standard labour supply model this turns out to be a convenient way to enter demand side factors directly into the determination of an individual s labour market position the model is applied with some success to the working behaviour of married women in the uk family expenditure survey

policy impacts under rational expectations abstract this paper re examines for the u s the validity of the macro rational expectations mre hypothesis in contrast to most previous studies in this area the paper a considers the potential real effects of both monetary and fiscal policies b allows for possible endogeneity of these policies and c uses a joint non linear estimation methodology to distangle the hypothesis of rationality from that of neutrality the empirical results reject the joint mre hypothesis for both policies the results also indicate that policy non neutrality is the culprit behind such rejection this evidence offers further empirical support for macro rational expectations models where monetary and fiscal policies can due to some rigidities play a key role in stabilizing the real economy

how reliable is duality theory in empirical work the neoclassical theory of production establishes a dual relationship between the profit value function of a competitive firm and its underlying production technology this relationship commonly referred to as duality theory has been widely used in empirical work to estimate production parameters such as elasticities and returns to scale we generate a pseudo dataset by monte carlo simulations which starting from known production parameters yield a dataset with the main characteristics of u s agriculture in terms of unobserved firm heterogeneity decisions under uncertainty unexpected production and price shocks endogenous prices output and input aggregation measurement error in variables and omitted variables production parameters are not precisely recovered when performing econometric estimation based on the duality approach and the elasticity estimates are inaccurate deviations of own and cross price elasticities from initial median values given our parameter calibration range between 6 and 690 with an average of 90 also own price elasticities are as imprecisely recovered as cross price elasticities sensitivity analysis shows that results still hold for different sources and levels of noise and sample size used in estimation

monetary variability and real output abstract utilizing engel s econometrica 1982 50 987 1008 autoregressive conditional heteroskedasticity arch model to consistently parameterize the conditional variance of money growth i find an inverse relationship between monetary variability and real output this provides some additional evidence in favor of friedman s journal of political economy 1977 85 451 472 famous conjecture

labour force transitions among low wage married couples a simultaneous probability model interdependence in the labour force transitions of low income married couples is studied it utilizes a simultaneous probability model in which each person s job exit depends in part on the job transitions of their spouse estimates are based on data from the seattle denver income maintenance experiments the evidence appears to indicate that wives emulate the nonwork status of their husbands wives of exit prone husbands are themsleves more exit prone and less likely to enter employment evidence in favour of reverse dependence of husbands status on wives exits appears to be weak and imprecise

the expectation hypothesis of the term structure of very short term rates statistical tests and economic value this paper re examines the validity of the expectation hypothesis eh of the term structure of us repo rates ranging in maturity from overnight to three months we extend the work of longstaff 2000a in two directions i we implement statistical tests designed to increase test power in this context ii more importantly we assess the economic value of departures from the eh based on criteria of profitability and economic significance in the context of a simple trading strategy the eh is rejected throughout the term structure examined on the basis of the statistical tests however the results of our economic analysis are favorable to the eh suggesting that the statistical rejections of the eh in the repo market are economically insignificant

fiscal deficits and long term interest rates further evidence from annual data much debate has recently centered on the popular view that large u s budget deficits financed by the sale of bonds cause high interest rates if valid this view implies that deficits crowd out efficient private investment and adversely affect economic growth however bailey 2 and barro 3 have challenged this conventional view on theoretical grounds based on the ricardian equivalence proposition bailey and barro contend that rational economic agents interpret government deficits as postponed tax liabilities and thus will have no effects on private wealth or interest rates such theoretical ambiguity in regards to the impact of budget deficits has also been matched by an equally conflicting empirical evidence for example barth iden and russek 4 deleeuw and holloway 8 hutchison and pyle 20 makin 24 makin and tanzi 25 and zahid 35 have found a positive and significant effect of deficits on interest rates on the other hand evans 11 12 13 hoelscher 17 motley 28 and plosser 29 30 have all failed to find any systematic support for a significant positive impact of deficits on interest rates it should be observed that the above empirical studies have employed either monthly or quarterly data however some researchers e g hoelscher 18 have recently charged that monthly or quarterly data bias the results in favor of finding no significant linkage between deficits and interest rates they reasoned that portfolio adjustment lags are too long for monthly or even quarterly observations to reflect the actual correlation between deficits and interest rates to eliminate this problem of periodicity annual data was instead advocated 2 using annual data hoelscher 18 concluded that deficits have caused positive and significant changes in long term interest rates in the united states

anticipated monetary policy and real output evidence from latin american countries this paper is an empirical investigation of the effects of anticipated and unanticipated monetary policies on real output for 13 ldcs in latin and central america the well know mishkin econometric procedure is applied to the annual imf date for the decomposition of actual money growth into anticipated and unanticipated components and the evidence of significant relation between anticipated money supply and real output for each country is reported the results derived in this paper thus provide additional empirical support for the validity of the non classical rational expectations macro models of fisher and phelps and taylor

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

effects of fiscal policies on us agriculture according to the macro rational expectation mre hypothesis only unanticipated macroeconomic policy has impacts on real economic variables and anticipated policy changes have no real impacts this study analysis the effects of the anticipated and unanticipated components of fiscal policy on the us farm real gnp by testing the neutrality and rationality propositions of the mre hypothesis the test results show that both the rationality and neutrality propositions are rejected the empirical findings indicate that the anticipated fiscal policy does have significant effects on farm output examination of a specific sector sheds light on the nature of the market and helps ascertain the resons for the non neutrality

two moment decision models and expected utility maximization two moment decision models are consistent with expected utility maximization only if the choice set or the agent s preferences are restricted this paper identifies a restriction which is sufficient to ensure this consistency and confirms that it holds in many economic models the implications for economic analysis are then derived two different approaches to representing an agent s preferences over strategies yielding random payoffs are in wide use under the mean standard deviation ms approach the agent is assumed to rank the alternatives according to the value of some function defined over the first two moments of the random payoff while the expected utility eu criterion assumes that the expected value of some utility function defined over payoffs is used instead the fact that there are these two competing approaches has generated a considerable literature some authors are concerned with the advantages and disadvantages of each while others deal with conditions under which the potentially different approaches would yield the same results or at least approximately so space does not

modeling the reforms of the common agricultural policy for arable crops under uncertainty the size of the insurance and wealth effects of a change in the common agricultural policy cap for arable crops is estimated the impact of price uncertainty is accounted for in the specific decision making structure of the european union eu arable crop producers under nonlinear mean variance risk preferences a system of output supply input demand and land allocation equations is estimated on a sample of italian specialized arable crop farms the simulation of the impact of the recent reforms confirms that farmers output responses are consistently affected by the size of the insurance and wealth effects

the effects of monetary policy news and surprises there is substantial agreement in the monetary policy literature over the effects of exogenous monetary policy shocks the shocks that are investigated however almost exclusively represent unanticipated changes in policy which surprise the private sector and which are typically found to have a delayed and sluggish effect on output in this paper we estimate a new keynesian model that incorporates news about future policies to try to disentangle the anticipated and unanticipated components of policy shocks the paper shows that the conventional estimates confound two distinct effects on output an effect due to unanticipated or surprise shocks which is smaller and more short lived than the response usually obtained in the literature and a large delayed and persistent effect due to anticipated policy shocks or news news shocks play a larger role in influencing the business cycle than unanticipated policy shocks although the overall fraction of economic fluctuations that can be attributed to monetary policy remains limited

on the asymmetric effects of money supply shocks international evidence from a panel of oecd countries we examine whether the asymmetric effect of money on output is an international phenomenon and investigate the reasons for this asymmetry quarterly data from the 1963 93 period for a panel of twelve oecd countries strongly support asymmetry internationally negative money supply shocks are shown to have a stronger effect on output than positive shocks our methodology also enables us to distinguish between two sets of theories consistent with the output asymmetries a convex aggregate supply and a credit view we find that the effects of money on prices are generally symmetric which may be consistent with both sets of theories being operative at once

married women s hours and participation revisited elasticity estimates are presented for participation and hours of work for a sample of married women in the social change and economic life initiative sceli 1986 data set a logit model is used to estimate the participation function and a tobit model is employed to estimate an hours of work equation the results are in agreement with the evidence available for the uk the own wage hours of work elasticity is found to be relatively elastic with negligible effects detected for non labour income and the husband or spouse s wage the effects on participation of an unemployed husband or spouse were examined and found to have a strong negative effect

benefits and the labour supply of women married to unemployed men this paper seeks to explain the low labor force participation rates of women married to unemployed men in the reducing the net increment to household income that would result from the wife s employment simple probit models of the participation and part time full time decisions are estimated using a large cross sectional data set the results confirm the importance of severe disincentive effects controlling for labor market conditions income related benefits are found to create worse problems than national insurance benefits both types impede part time work in particular copyright 1990 by royal economic society

husband s unemployment and wife s labor supply the added worker effect across europe this article investigates the responsiveness of women s labor supply to their husband s job loss the so called added worker effect the authors contribute to the literature by taking an explicit internationally comparative perspective in analyzing the variation of the added worker effect across welfare regimes using longitudinal data from the european union statistics on income and living conditions eu silc survey covering 28 european countries from 2004 to 2013 they find evidence of an added worker effect which however varies over both the business cycle and the different welfare regimes in europe the latter result might be explained in part by differences in the design of the unemployment benefit system across countries which create different incentives for the labor supply of wives of unemployed men

anticipated money unanticipated money and output 1873 1930 anticipated money unanticipated money and output 1873 1930 i introduction this paper examines the roles of anticipated and unanticipated money in the period between the civil war and the depression 1 such an examination is warranted for at least two reasons first estimation of the impact of anticipated and unanticipated money on output for historical periods can enhance our understanding of the responses of economic activity to these key variables 2 second recent work has shown that traditional historical estimates of output may be faulty see romer 1986a 1986b 1986c 1988 not only do most studies investigating the economic roles played by anticipated and unanticipated money concentrate on the post world war ii era those that discuss the period before world war ii such as rush 1985 1986 use traditional data indeed despite the interesting analyses by rush if the validity of the conventional data on output and unemployment for the era under consideration is rejected then virtually no results on the importance of monetary and real factors for economic activity are available for this important period thus further discussion of this topic is needed to answer two important questions what do the revised data show us about the historical economy do these revisions change the inferences drawn about monetary influences on economic activity the analysis presented here is comprehensive in that a wide range of output measures are employed both in terms of the types of output and in terms of the manner in which the output measures are constructed given this variety in the output measures consistent results on the effects of anticipated and unanticipated money across output measures indicate that conclusions drawn from the analysis are robust in particular the empirical results presented below support the following hypotheses i that anticipated m2 and monetary base growth have no effect on output regardless of the output measure used ii that unanticipated m2 and monetary base growth do effect output regardless of the output measure used and iii that changes in financial intermediation may be important for the evolution of output over time support for hypotheses i and ii is consistent with the monetary explanation of business cycles support for hypotheses iii may be consistent with real explanations of business cycles if exogenous shocks to the monetary production technology subsequently affect output 3 taken together the joint support for hypotheses i iii suggests that at a minimum neither the real nor the monetary explanations for historical u s business cycles can be discounted without additional work the remainder of the paper is organized as follows section ii presents a brief overview of the historical period under consideration along with a discussion of prior work on the effects of anticipated and unanticipated money on output determination during this time period section iii discusses the data and the methodology the empirical results are presented in section iv and the conclusions in section v ii overview the historical period the period under investigation 1873 1930 is one of substantial economic change banking panics the return to the gold standard the founding of the federal reserve system and world war i are some of the more important events occuring during this period we consider the role played by expected and unexpected money in output determination for several major subperiods while data availability largely determined the selection of these subperiods they generally correspond to major economic events despite the structural and institutional changes over the period we also examine the roles of anticipated and unticipated money growth in the determination of output over the entire time period to be valid tests of the impact of money growth on output require a reasonable degree of homogeneity in the economic environment

structural federal deficits and interest rates some causality and co integration tests the relationship between federal budget deficits and interest rates has been the focus of extensive research recently cebula 4 examined this relationship empirically and concluded that the federal budget deficit does in fact exercise a positive and significant impact upon the nominal moody s aaa rated corporate bond rate 4 208 such a finding is at odds with the great majority of recent empirical studies in this area if valid this finding assigns to large deficits significant adverse effects on both private investment crowding out and on trade balance via an overvalued dollar given these profound public policy implications cebula s finding warrants further examination

testing expected utility maximization under price and quantity risk with a heterogeneous panel refutable implications based on the curvature properties of the indirect utility function for the competitive firm operating under uncertainty are extended to the case of both price and quantity uncertainty using unit roots and cointegration tests for heterogeneous panels a model of us agricultural production is developed based on the time series properties of a panel of state level data most refutable hypotheses under output price and output quantity risk are not rejected but symmetry conditions implied by a twice continuously differentiable indirect utility function are rejected the same test conclusions are obtained from a traditional model that presumes stationarity in all variables

fisher phillips friedman and the measured impact of inflation on interest a reply the purpose of this paper is to demonstrate that empirical findings which persistently appear to contradict the fisher hypothesis that the nominal rate of interest should rise by the full amount of an increase in anticipated inflation are due basically to a failure to control for changes in the real rate of interest that are associated with changes in anticipated inflation we are guided in our search for proper specification of a fisher equation by a simple general equilibrium model which is employed to derive the impact of a change in anticipated inflation upon nominal interest given the requirement that commodity money and labor markets remain in equilibrium in effect we depart from the empirical tradition which has grown up around testing of the fisher hypothesis that takes the real interest rate to be independent of anticipated inflation and argues that for anticipated inflation properly measured the data ought to support the fisher hypothesis 1

econometric issues in macroeconomic models with generated regressors the paper critically reviews the literature on the econometric issues raised by the use of generated regressors gr in empirical models the economic rationale for the use of gr is considered with examples being drawn from several macroeconomic examples including new classical macroeconomic ncm models which postulate monetary neutrality various estimation methods are discussed for models which include surprise or unexpected terms and the strengths and weaknesses of each approach are investigated drawing upon the work of mcaleer and mckenzie 1991 situations where the typically inefficient two step estimation 2se method will be efficient are highlighted problems of model misspecification and measurement errors are also investigated an empirical section highlights some of the dangers of using uncorrected 2se estimation results through a careful consideration of many recent attempts to test the ncm monetary neutrality hypothesis copyright 1993 by blackwell publishers ltd

empirical evidence on nominal wage and price flexibility this paper tests a necessary condition for the neutrality of money in a framework that imposes only weak restrictions on the money supply process it extends bernanke s 1986 work by weakening the set of just identifying restrictions and by providing a statistical test of the overidentifying restrictions instead of specifying a structural model to identify primitive shocks i deduce the impact effects of structural money shocks under the neutrality hypothesis and then test whether the system maintains neutrality as it propagates these impact effects the tests reject neutrality for both the m1 and the monetary base

social security policy in a changing labour market conditions in the uk labour market of the 1990s are markedly different from those which prevailed in the post war period when the modern welfare state was created the main differences include a growth in long term unemployment in female part time employment and in low paid employment and self employment in some respects social security policy has adapted to reflect these new patterns the clearest example of this is the introduction and enhancement of in work benefits such as family credit however two of the main strands of benefit policy in recent decades greater reliance on family based means testing and an increased role for private insurance do not fit so well with labour market trends in the case of the privatization of mortgage insurance the result is likely to be further redistribution away from those in insecure or low paid employment copyright 1995 by oxford university press

federal deficits and money growth in the united states a vector autoregressive analysis abstract a multivariate var modelling technique is employed in this paper to test for causality between federal deficits and money growth in the united states four alternative causality hypotheses including the common accommodation view are examined in addition to the two policy variables four other related macro variables are included in the empirical analysis namely short term interest rates prices real output and exchange rates the var results consistently reject the accommodation hypothesis and indicate that monetary and fiscal policy actions are set independently in the united states other causality inferences are also obtained and their implications are discussed

a model of female labour supply in which supply is dependent upon the chances of finding a job in this paper we extend a model of female labour supply by considering the impact of the local labour market thus in our model a woman supplies her labour if she has both made the decision to participate and found a job this extension is of particular importance in times of high unemployment when discouraged worker effects will be at their strongest we also consider the contribution of such a model to the debate concerning the labour supply of women married to men who are unemployed

anticipated federal budget deficits monetary policy and the rate of interest in recent years a number of studies have attempted to investigate the impact of federal budget deficits on the rate of interest studies by evans 6 7 makin 13 hoelscher 9 10 barth iden and russek 2 3 dwyer 5 cebula 4 among others have analyzed this issue but have provided conflicting evidence on the impact of federal budget deficits on the rate of interest this is due in part to differences in methodology definition of budget deficit variables sample period and estimation techniques hoelscher 10 barth iden and russek 2 3 feldstein and eckstein 8 find that budget deficits affect interest rates but evans 6 7 makin 13 and hoelscher 9 conclude that budget deficits have no significant effect on interest rates the contributions of this paper are first to directly introduce within the framework of rational expectations models federal budget deficit and monetary variables this technique of analyzing the impact of deficits on interest rates may shed new light on this important issue which has not appeared in the literature second the deficit measure employed in this study is designed in a manner that it avoids being contaminated by changes in expenditures and tax receipts due to the automatic stabilizing aspects of fiscal policy third it is explicitly recognized that monetary and fiscal policies jointly interact in determining interest rates finally the policy process determining the interest rate is tested for stability over time this is important in light of evans s 6 work who finds various episodes in the u s history when budget deficits increased for a few years but had no appreciable impact on interest rates the intention in this paper is to investigate the reaction of economic agents who find that budget deficits may persist for a longer time in the future

risk aversion and price risk in duality models of production a linear mean variance approach a duality model of production is developed that permits risk aversion and price uncertainty the linear mean variance framework employed is tractable for empirical research in contrast to duality models of risk based on a generalized expected utility function the framework is more general than in standard price certainty models while retaining the simplicity needed for empirical research

risk aversion and yield uncertainty in duality models of production a mean variance approach a duality model of production is developed that endogenizes stochastic output decisions under risk aversion the model incorporates both yield and price uncertainty and nonlinear mean variance risk preferences this permits modeling of the firm s expected output supply and input demand decisions under risk and also in principle the firm s output variance decisions the duality model is tractable for empirical research

estimating economies of scope and scale under price risk and risk aversion this study uses duality to examine the effects of excluding output price risk and risk aversion on cost structures using data for kansas wheat and beef cow operations a dual risk model was used to determine multi product and product specific scale economies and economies of scope estimates for these measures were compared with those obtained from a deterministic model the results show that product specific scale economies are over estimated and economies of scope and multi product scale economies are under estimated for the deterministic model compared to the risk model

inter and intra seasonal crop acreage response to international food prices and implications of volatility understanding how producers make decisions to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for predicting the supply of staple crops and hence assessing the global food supply situation this study makes estimations of monthly i e seasonal versus annual global acreage response models for the world s principal staple food crops wheat corn soybeans and rice primary emphasis is given to the magnitude and speed of the allocation process estimation of intra annual acreage elasticity is crucial for expected food supply and for input demand especially in the light of the recent short term volatility in food prices the econometric results indicate that global crop acreage responds to crop prices and price risks input costs as well as a time trend depending on respective crop short run elasticities are about 0 05 to 0 40 price volatility tends to reduce acreage for some of the crops comparison of the annual and the monthly acreage response elasticities suggests that acreage adjusts seasonally around the globe to new information and expectations given the seasonality of agriculture time is of an essence for acreage response the analysis indicates that acreage allocation is more sensitive to prices in the northern hemisphere spring than in winter and the response varies across months

comparing the point predictions and subjective probability distributions of professional forecasters we use data from the survey of professional forecasters spf to compare point predictions of gross domestic product gdp growth and inflation with the subjective probability distributions held by forecasters we find that most spf point predictions are quite close to the central tendencies of forecasters subjective distributions tend to be asymmetric with spf forecasters tending to report point predictions that give a more favorable view of the economy than do their subjective means medians modes

aggregation of price risk over commodities an economic index number approach this article extends the economic theory of index numbers to the aggregation of price risk over commodities in production superlative indexes of aggregate price risk are related to tornqvist and fisher type output quantity indexes an application to major crops in manitoba illustrates the empirical importance of the analysis

do counter cyclical payments in the 2002 us farm act create incentives to produce analytical results in the literature suggest that counter cyclical payments create risk related incentives to produce even if they are decoupled under certainty hennessy d a 1998 the production effects of agricultural income support polices under uncertainty am j agric econ 80 46 57 this paper develops a framework to assess the risk related incentives to produce created by commodity programmes like the loan deficiency payments ldps and the counter cyclical payments ccps in the 2002 us farm act because ccps are paid based on fixed production quantities they have a weaker risk reducing impact than ldps the latter have a direct impact through the variance of the producer price distributions while the impact of ccps is due only to the covariance between the ccp and the producer price distributions the methodology developed by chavas j p holt m t 1990 acreage decisions under risk the case of corn and soybeans am j agric econ 72 3 529 538 is applied to calculate the appropriate variance covariance matrix of the truncated producer price distributions under the 2002 farm act risk premia are computed showing that the risk related incentives created by ccps are significant and do not disappear for levels of production above the base production on which ccps are paid

does anticipated monetary policy matter an econometric investigation a heated debate has arisen over the policy ineffectiveness proposition associate with the work of lucas sargent and wallace it postulates that anticipated aggregate demand policy will have no effect on business cycle fluctuations so that one deterministic feedback policy rule is as good as any other from the point of view of stabilizing the economy this paper develops a methodology for empirically analyzing rational expectations models displaying this neutrality result and then applies it to the important question of whether anticipated monetary policy matters to the business cycle

indexation and the effect of inflation uncertainty on real gnp this article examines the combined effects of inflation uncertainty and indexation on the growth rate of real gross national product gn p the evidence suggests that greater indexation partially reduces t he adverse effect of inflation uncertainty on real gnp growth over time it also indicates that in contrast to earlier findings regarding th e effect of inflation uncertainty on employment the overall effect of inflation uncertainty on real gnp growth may be permanent a preliminary assessment of whether the discrepancy is the result of in flation uncertainty permanently affecting the growth rate of the capi tal stock is inconclusive copyright 1988 by the university of chicago

forecasting rational expectations and the phillips curve an empirical investigation abstract the rational expectations version of the phillips curve is empirically evaluated for switzerland using a wide variety of specifications it turns out that the results are highly sensitive to measurement of both the natural rate and expectations of nominal variables no reliable phillips curve seems to exist in addition information on the relative quality of different forecasting schemes is obtained for a number of important macroeconomic variables

panel data estimation techniques and farm level data models econometric models wishing to estimate relevant parameters for agricultural policy analysis are increasingly relying on unbalanced panels of farm level data since in the agricultural economics literature such models have often been estimated through simplified approaches in this paper we try to verify whether the adoption of more sophisticated panel data techniques may impact the estimation results for this reason the policy model by moro and sckokai 1999 has been re estimated using techniques recently developed in the econometric literature the preliminary results show a strong impact on the estimations this seems to suggest that the adoption of proper panel data techniques is likely to be very important in order to obtain reliable estimates of some key policy parameters

allocatable fixed inputs and two stage aggregation models of multioutput production decisions allocation decisions for a fixed input such as land are incorporated into a two stage aggregation model of multioutput production decisions the resulting two stage model is more realistic and is as tractable for empirical research as the standard model

interest rate variability and economic performance some international evidence using data for short term and long term interest rates across a major group of industrial countries his paper studies the impact of interest rate variability on the cyclical behaviour of real output and the price level in these countries theory predicts that the increased variability of the interest rate stemming from a rise in the level of uncertainty has a negaive impact on he ouput demanded and supplied and in turn an ambiguous impact on the price level the empirical evidence is generally consistent with this prediction next the investigation attempts to shed some light on major sources of uncertainty underlying the interest rate variability focus in on he variability of monetary growth the exchange rate and the energy price some evidence on he relative contribution of these sources of uncertainty of the variability of the interest rate and in turn to the cyclical behaviour of real output and the price level across countries is provided

pesticide use environmental spillovers and efficiency a dea risk adjusted efficiency approach applied to dutch arable farming pesticides are widely used by crop producers in developed countries to combat risk associated with pests and diseases however their indiscriminate use can lead to various environmental spillovers that may alter the agricultural production environment thus contributing to production risk this study utilises a data envelopment analysis dea approach to measure performance of arable farms incorporating pesticides environmental spillovers and output variance as undesirable outputs in the efficiency analysis and taking explicitly into account the effect of pesticides and other inputs on production risk the application focuses on panel data from dutch arable farms over the period 2003 2007 a moment approach is used to compute output variance providing empirical representations of the risk increasing or decreasing nature of the used inputs finally shadow values of risk adjusted inputs are computed we find that pesticides are overused in dutch arable farming and there is a considerable evidence of the need for decreasing pesticides environmental spillovers

uncertainty duality and perversity an empirical test of the schultz baron hypothesis it has been suggested that supply curves may be negatively sloped under conditions of output price uncertainty and risk aversion if the effect of an increase in expected price is offset by the effect of an associated increase in uncertainty risk this hypothesis first articulated by schultz and given a more rigorous theoretical exposition by baron is tested using aggregate time series data to estimate a stochastic model of us agriculture based on a generalized leontief certainty equivalent profit function evidence of risk aversion and a positive correlation between mean output price and its variance are found however these factors are not strong enough to generate perversity thus the own price elasticity of supply of agricultural output is found to be positive with a value of 0 25 although no evidence of perversity is found the empirical results suggest that ignoring price uncertainty may bias estimates of aggregate supply response downwards by between 5 and 47 as well as testing the schultz

the impact of decoupled payments on farm choices conceptual and methodological challenges abstract in this paper we review the methodological framework for analysing decoupled payments in models of agricultural production market and technological uncertainty farm efficiency credit constraints farm household choices involving extra agricultural decisions policy uncertainty and long run impact of decoupling on investment and land values are the relevant issues that should be pursued by methodological and empirical analysis future research should refine the analysis of decoupled payments mainly trying to provide results that can be useful for policy simulation to bridge the gap between analysis at the individual level and sector policy models

estimation of australian wool and lamb production technologies under uncertainty an error components approach a model of producer behavior which explicitly accounts for both output price and production uncertainty is formulated and estimated if the production technology is multiplicatively separable in its deterministic and stochastic components then the expected utility maximization problem implies cost minimization for planned or expected output consequently our empirical model of three lamb and wool producing sectors in australia involves the estimation of a system of input cost share and cost equations whose disturbances have an error components structure the empirical results are evaluated in terms of input demand elasticities and estimates of the stochastic components of production are presented

household unemployment and the labour supply of married women a recent reform to the uk unemployment insurance ui system has reduced the duration of entitlement from 12 to six months the ui and welfare systems interact in the uk in such a way that exhaustion of ut for married individuals has potentially large disincentive effects on the labour supply of spouses a model of labour supply is estimated for married women allowing for endogenous unemployment durations of husbands and wives we distinguish between transfer programme induced incentive effects correlation between labour supply and wages within couples complementarity between the leisure times of spouses and a discouraged worker effect

unanticipated money growth and unemployment post sample forecasts in the late 1970s robert j barro published what has since become a popular model of business fluctuations barro s 3 findings provide evidence advocating the short run neutrality of money under rational expectations forging an important empirical link to the theoretical studies of lucas 19 20 and sargent and wallace 33 the original barro unemployment model has received additional support from further statistical testing 5 6 15 despite criticisms and modifications some of which are considered in barro s 6 updated model these equations have inspired numerous empirical studies analyzing unanticipated effects of macroeconomic variables this paper examines post sample forecasts of barro s original 3 and revised 6 unemployment equations for the 1974 84 period mayer 23 24 harvey 13 179 80 and lovell 18 among many contend that the ability to successfully forecast outside of the sample period is an important criterion for evaluating model robustness this view is also reflected in a substantial body of studies including 10 25 26 29 39 which investigate the post sample predictive performance of macroeconomic models one year ahead forecasts indicate that the barro 3 6 equations accurately predict unemployment for the 1974 79 period during 1980 84 however the predictive performance of both models sharply deteriorates augmenting the barro models with interest rate volatility in accordance with the findings of evans 11 and tatom 38 considerably improves the overall forecasting ability this modification also rectifies the 1980s structural instability of the barro unemployment equations furthermore the basic conclusions of the seminal barro work are retained with this augmented model the results reveal that increases in interest rate volatility exert significantly adverse effects upon unemployment corroborating with the findings of evans 11 and tatom 38 still interest rate volatility could be overlooked in previous estimations of the barro or other models of business fluctuations due to the variable s relative constancy prior to 1979

anticipated money inflation uncertainity and real economic activity this paper critically examines a number of maintained hypotheses that are necessarily being tested along with the basic notion derived from the rational expectations re formulation of lucas 1972 19 73 that only unanticipated money matters the trend stationary representation of secular real output of lucas and others is replaced by a difference stationary representation found by nelson and plosser 1980 to be consistent with u s historical data the impact of inflation uncertainty on real activity is considered attention is paid to possible mis measurement of agents ex ante anticipated money growth it is found that three alternative measures of anticipated money growth produce a stable impact on growth of output and employment contemporaneous and lagged values of unanticipated money growth have no significant additional explanatory power in the presence of any one of the three measures of anticipated money growth beyond this it is impossible to reject the hypothesis that the initial positive real impact of anticipated money is not temporary inflation uncertainty is found to act as a significant depressant of real economic activity in the presence of all tested combinations of anticipated and unanticipated money growth this abstract was borrowed from another version of this item

real business cycles and the lucas paradigm when the lucas paradigm is generalized to include real effects the effects of real factors and monetary factors on the business cycle are always interrelated furthermore in such models monetary factors can affect the long run behavior of real output contrary to the commonly held view that they cannot real business cycle models and lucas type models are different paradigms but not in the sense of real versus monetary rather interrelationships between real and monetary factors are intrinsic to the lucas paradigm whereas the real business cycle literature implies a dichotomy between real and monetary factors

inflation uncertainty and real economic activity an alternative approach a bstracct increased uncertainty about inflation is shown to encourage inflation hedging which in turn reduces the macroeconomic costs of that uncertainty portfolio theory and empirical evidence support the contention that only the portion of inflation volatility that cannot be hedged has real economic effects additional empinrcal results suggest that i increased inflation volatility in the early seventies was eventually followed by portfolio reallocations that allowed for greatly improved inflation hedging and ii the deletenrous effect of inflation uncertainty on real economic activity shown in previouis studies is significantly smaller after 1975
