what accounts for the changes in u s fiscal policy transmission using vector autoregressions on u s time series for 1957 79 and 1983 2004 we find government spending shocks to have stronger effects on output consumption and wages in the earlier period we try to account for this observation within a dsge model featuring price rigidities and limited asset market participation specifically we estimate the structural parameters of the model for both periods by matching impulse responses model based counterfactual experiments suggest that most of the changes in fiscal policy transmission are accounted for by increased asset market participation and the more active monetary policy of the volcker greenspan period

how should control theory be used to calculate a time consistent government policy we study different solutions to a simple one dimensional linear quadratic game with a large number of private agents and a government a time consistent solution is defined as a solution to the hamilton jacobi bellman equation i e as a policy for which the government has noprecommitment capability this solution is compared to a policy where the government has an instantaneous pre commitment i e an equilibrium in which the government has a period by period leadership in both cases we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature

short term inflation expectations evidence from a monthly survey note the assumption that economic agents have rational expectations is commonplace in studies of macroeconomic policy and asset market behavior research examining observable expectations from surveys however has generally found that the data reject the rational expectations hypothesis friedman 1980 reports that forecasts of long term interest rates from surveys of financial market participants are not rational figlewski and wachtel 1981 note that most investigators of the livingston survey data on economists inf lation expectations conclude that these data do not conform to the rational expectations hypothesis british survey data on the inflation expectations of consumers analyzed by evans and gulamani 1984 and on the inflation expectations of business firms examined by pesaran 1985 also appear inconsistent with rational expectations the failure of survey data to pass tests of rationality have led researchers such as mishkin 1983 to question the usefulness of survey data to proxy expectations this paper examines a different source of expectations data namely the surveys of money market participants conducted by money market services inc mms data from the mms surveys have been widely used in studies of how asset prices respond to unanticipated changes in economic variables recent papers by urich and wachtel 1984 pearce and roley 1985 and smirlock 1986 employ the median predicted inflation rate from the mms survey to construct a measure of the unexpected component of inflation announcements

the speculative attack on the peso and the real exchange rate argentina 1979 1981 abstract this article applies a speculative attack model to argentina during its pre announced exchange rate system from january 1 1979 to june 30 1981 the model attempts to verify a rule whereby if domestic credit growth exceeds the rate of currency depreciation two things occur first the domestic price of non traded goods rises relative to the price of traded goods second foreign reserves decline until a point when a sudden speculative attack depletes remaining reserves causes a precipitous fall in the relative price of non tradables and forces the country onto a floating exchange rate regime in some important respects the model captures the argentinian experience yet in other respects if fails to do so

pooling forecasts in linear rational expectations models abstract estimating linear rational expectations models in a limited information setting requires replacing the expectations of future endogenous variables either with instrumented actual values or with forecast survey data applying the method of gottfries and persson empirical examinations of the information sets of economic agents quarterly journal of economics 103 251 259 i show how to augment these methods with actual future values of the endogenous variables to improve statistical efficiency the method is illustrated with an application to the us hybrid new keynesian phillips curve where traditional lagged instruments and the median forecast from the survey of professional forecasters both appear to miss significant information used by price setters so that forecast pooling with actual values improves the statistical fit to inflation

declining volatility in the u s automobile industry dramatic changes in the volatility of output occurred in the u s auto industry in the early 1980s namely output volatility declined the covariance of inventory investment and sales grew more negative and adjustments to production schedules which in earlier decades stemmed primarily from plants hiring and laying off workers were more often accomplished with changes in average hours per worker after the mid 1980s using a linear quadratic inventory model with intensive and extensive labor adjustments we show how all of these changes could have stemmed from one underlying factor a decline in the persistence of motor vehicle sales jel g31 l25 l62 m11

empirical evidence on inflation expectations in the new keynesian phillips curve abstract we review the main identification strategies and empirical evidence on the role of expectations in the new keynesian phillips curve paying particular attention to the issue of weak identi

expectations as a source of macroeconomic persistence evidence from survey expectations in a dynamic macro model abstract embedding survey expectations in a standard dsge model helps to identify key slope parameters in standard relationships dramatically reduces the need for lagged dependent variables often motivated by price indexation and habit formation and obviates the need for autocorrelated structural shocks in the key equations formal statistical tests demonstrate that much of the persistence in aggregate data is better accounted for by slow moving expectations rather than by habits indexation and autocorrelated structural shocks

making weak instrument sets stronger factor based estimation of inflation dynamics and a monetary policy rule the problem of weak identification has recently attracted attention in the analysis of structural macroeconomic models using robust methods can result in large confidence sets making precise inference difficult we overcome this problem in the analysis of the hybrid new keynesian phillips curve and a forward looking taylor rule by employing stronger instruments we suggest exploiting information from a large macroeconomic data set by generating factors and using them as additional instruments this approach results in stronger instrument sets and hence smaller weak identification robust confidence sets it allows us to conclude that there has been a shift toward more active monetary policy from the pre volcker regime to the volcker greenspan tenure

inflation dynamics the role of expectations the modelling of expectations and its degree of backward looking behaviour are issues of main concern in the in ation dynamics research agenda one approach in the literature is to use expectations from surveys as an approximation to actual expectations this method avoids particular assumptions on expectations and their degree of rationality we estimate the phillips curve allowing for a simultaneous role of rational and survey expectations we formulate both a generalization of the usual phillips curve and a structural version in the spirit of gal and gertler 1999 we flnd that marginal cost determines in ation while the role of detrended output appears to be problematic we also flnd that survey expectations are an important component of in ation dynamics but they do not fully re ect economic agents rationality a signiflcant level of rationality is found even when controlling for survey expectations jel classiflcation e31

testing the rationality of inflation forecasts from survey data another look at the src expected price change data this paper develops a unified econometric approach for testing the rationality of expectations from survey data series the paper employs the estimation techniques of hansen 1982 and eichenbaum hansen and singleton 1982 to conduct tests of unbiasedness efficiency and orthogonality for the src expected price change data in contrast to the existing literature the analysis takes careful account of serial correlation and conditional heteroskedasticity in the disturbance terms the results do not reject the properties of unbiasedness efficiency or othogonality for this survey data series copyright 1989 by mit press

dynamic inconsistencies counterfactual implications of a class of rational expectations models a number of recent papers have developed dynamic macroeconomic models that incorporate rational expectations and optimizing foundations while the theoretical motivation behind these models is sound the dynamic implications of many of the specifications that assume rational expectations and optimizing behavior can be seriously at odds with the data for both inflation and real side variables exhibit gradual and hump shaped responses to real and monetary shocks for models that are intended for monetary policy analysis these dynamic shortcomings should be considered quite serious when monetary policy has only short run effects on real variables the inability to approximately capture the short run responses of inflation or real variables to policy shocks makes a model unsuitable for policy analysis this paper identifies a simple feature common to many dynamic specifications for prices and real variables that causes the problem the paper also discusses several potential solutions to the problem including alterations to the expectations assumption to the order of differencing implicit in the model and to the underlying behavioral assumptions this abstract was borrowed from another version of this item

let the good times roll the economic expectations of u s voters increasingly the concept of expectation is utilized to explain political choices with voters being depicted as prospective rather than retrospective in their orientations this paper tests competing theories of economic expectations forecasts with data from consumer surveys 1960 91 forecasts of inflation confirm the hypothesis of adaptive expectations but forecasts of general economic conditions do not nor do those forecasts conform to rational expectations instead voter forecasts of economic conditions are prone to a significant asymmetry while good economic times tend to foster optimism in an adaptive fashion bad times do not similarly feed pessimism instead they trigger a reverse forecast we explore this remarkable behavior in the light of psychological economics

household versus economist forecasts of inflation a reassessment note in a recent article in this journal gramlich 1983 concluded that the mean inflation forecasts from the university of michigan survey research center src surveys of households were in the years 1956 1980 more accurate and more rational than the mean inflation forecasts from livingston s philadelphia inquirer surveys of professional economists these paradoxical elndings have proved robust with respect to improvements in testing procedures bryan and gavin 1986a 1 986b the purpose of this note is not to cast doubt on the result themselves but to urge caution in their interpretation with respect to forecast accuracy we show that while the average forecast from the src is indeed more accurate than the average forecast from the livingston survey the forecast of a typical household is much less accurate than that of a typical economist the apparent superiority of the src survey is entirely due to its larger

survey measures of expected u s inflation of real interest rates and cash flows for decisions concerning investment expenditures international capital flows and exchange rate movements hinge in large part on expected real yield differentials across countries the federal reserve needs reliable measures of expected inflation to formulate and gauge the thrust of monetary policy in fact inflation expectations have become more important to the fed given the diminished stability of the link between the monetary aggregates and gdp expenditures since the early 1980s and the greater role which has been thrust upon expected real short term interest rates in the implementation of federal reserve policy the issue of rationality of inflation expectations that is the extent to which agents form expectations without making systematic mistakes in their beliefs about what inflation will be is important if inflation expectations are formed rationally labor and financial markets will strongly tend to neutralize the potential redistributive effects of inflation over time financial capital will flow efficiently within and across national borders moreover some of the stronger claims of new classical macroeconomics like the claim that only unexpected monetary policy actions will

optimal anti inflation programs in semi industrialized economies orthodox versus heterodox policies abstract the paper characterizes the optimal time consistent anti inflation program in a small open semi industrialized economy when policy makers choose the rate of exchange rate crawl the rate of change of fiscal spending and a wage and price control parameter to minimize deviations of output and inflation the optimal program involves a rapidly decelerating rate of crawl a sharp reduction in spending and a short initial period of wage and price controls the paper also assesses the importance of controls in helping to reduce the output loss associated with fighting inflation

partisan preferences electoral prospects and economic expectations research shows that economic expectations reflect partisan preferences those who support the current government tend to think the future will go well at least by comparison with those who oppose the government but there always is uncertainty surrounding the political future especially in the period before elections this article considers whether the uncertainty matters specifically it examines whether people s economic expectations are conditional on their own estimates of who will win the analysis relies on data from five election study panels in the united states and the united kingdom both majoritarian systems where the effects of partisan winning and losing are most likely the results imply that people in these countries do anticipate election outcomes that is economic expectations prior to elections reflect both the political present and future this tells us not only that expectations in these systems are substantially rational but that politics plays a much bigger role in our economic

the genesis of inflation and the costs of disinflation this essay asks how high inflation arises and why it is costly to eliminate specifically the paper discusses the roles of price rigidity and credibility problems in explaining the costs of disinflation the puzzle of persistent inflation triggered by onetime macroeconomic shocks and the case for returning to adaptive expectations in theories of inflation this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

voters information heterogeneity and the dynamics of aggregate economic expectations theory it is argued here that previous studies analyzing the formation of voters economic expectations overlook important subtleties found in a differentiated heterogeneous electorate since different segments of the electorate possess varying information capabilities it is asserted that they will form their prospective economic evaluations differently from one another hypotheses the impact of expectational electoral cycles news coverage of the economy reported by voters retrospective economic evaluations and personal financial expectations are hypothesized to have a differential impact on their economic expectations based on varying levels of information education among subsets of the electorate methods time series multiple regression analysis is conducted for the monthly period between january 1978 and december 1990 the empirical analysis involves testing for the properties of the statistical time series i e integration and cointegration as well as specification of an error correction mechanism ecm that captures long run statistical relationships in appropriate circumstances results these findings uncover electoral heterogeneity based on information education differences with respect to voters prospective economic evaluations specifically the information capabilities of voters is inversely related to their reliance on past retrospective sources of information when forming both egocentric and sociotropic economic expectations the main implication of this research is that the assumption of electoral homogeneity contained in previous longitudinal analyses of aggregate economic opinion formation provides misleading results that either overlook intra electoral variations introduce aggregation bias or possibly both

the new keynesian phillips curve from sticky inflation to sticky prices the new keynesian phillips curve nkpc model of inflation dynamics based on forward looking expectations is of great theoretical significance in monetary policy analysis empirical studies however often find that backward looking inflation inertia dominates the dynamics of the short run aggregate supply curve this inconsistency is examined by investigating multiple structural changes in the nkpc for the u s between 1960 and 2005 employing both inflation expectations survey data and a rational expectations approximation we find that forward looking behavior plays a smaller role during the high and volatile inflation regime to 1981 than in the subsequent period of moderate inflation providing empirical support for sticky price models over the last two decades a break in the intercept of the nkpc is also identified around 2001 and this may be associated with u s monetary policy in that period

inflation dynamics when inflation is near zero this paper discusses the likely evolution of u s inflation in the near and medium term on the basis of 1 past u s experience with very low levels of inflation 2 the most recent japanese experience with deflation and 3 recent u s micro evidence on downward nominal wage rigidity our findings question the view that stable long run inflation expectations and downward nominal wage rigidity will provide sufficient support to prices such that deflation can be avoided we show that an inflation model fitted on japanese data over the past 20 years which accounts for both short and long run inflation expectations matches the recent u s inflation experience quite well while the model indicates that u s inflation might be subject to a lower bound it does not rule out a prolonged period of mild deflation going forward in addition our micro evidence on wages suggests no obvious downward rigidity in the firm s wage costs downward rigidity in individual wages notwithstanding as a consequence downward nominal wage rigidity may provide little offset to deflationary pressures in the current u s situation despite some circumstantial evidence that this channel might have been at work in the past

animal spirits the effect of economic expectations on economic output the public is characterized as able forecasters of future economic performance they engage in rational expectations empirical evidence exists to bolster the claim this article considers the possibility that the public does more than predict economic output they may engage in a self fulfilling prophecy where belief about the future economy translates into personal financial behaviour e g consumption and investment that actually drives economic performance after controlling for rational expectations with elite forecasts leading indicators and past economic performance it is shown that between 5 and one third of the variance in economic output can be explained by prospective economic sentiment this result has broad implications for electoral behaviour research

inflation expectations and behavior do survey respondents act on their beliefs we compare the inflation expectations reported by consumers in a survey with their behavior in a financially incentivized investment experiment the survey is found to be informative in the sense that the beliefs reported by the respondents are correlated with their choices in the experiment more importantly we find evidence that most respondents act on their inflation expectations showing patterns consistent with economic theory respondents whose behavior cannot be rationalized tend to have lower education and lower numeracy and financial literacy these findings help confirm the relevance of inflation expectations surveys and provide support to the microfoundations of modern macroeconomic models

backward looking indexation credibility and inflation persistence abstract inflation persistence is a stylized fact after disinflation standard staggered prices models show very little or no inflation persistence and hence are of little use when inflation is sticky in this paper i present a model that on the one hand is consistent with the evidence of sticky inflation and on the other can be directly incorporated into modern intertemporal optimizing models the model modifies calvo s calvo g 1983a staggered contracts and exchange rate policy in j a frenkel ed exchange rates and international economics university of chicage press chicago il calvo g 1983b staggered wages in a utility maximization framework journal of monetary ecomomics 12 3 383 393 exclusively forward looking model and includes a backward looking component it encompasses the two extreme cases of purely forward and backward looking price setting i show how the model can be used in open economy stabilization programs this is not the first model including a form of backward indexation in a staggered prices setting however it has the advantage of keeping the analytical elegance of the calvo model while enhancing its dynamics

a new view of political accountability for economic performance most political support models imply that in evaluating economic performance voters use a standard that would provide poor predictions of the future and leave the economy vulnerable to manipulation by vote hungry politicians drawing on macroeconomic theory we develop a simple standard of evaluation which encompasses a concern not only for current economic outcomes but also for accurately assessed future consequences of current policies we find that political support for the president can be explained as well by models that assume that voters use this sophisticated standard as by models that assume voter naivete our analysis questions the wisdom of measures typically used to assess voter evaluation of economic performance in a variety of theoretical contexts the results also help to explain the absence of convincing evidence that governments exploit voter ignorance in manipulating the economy

is inflation sticky abstract new keynesian sticky price models predict that monetary policy can affect real variables however they also predict that inflation can be reduced without depressing output or employment in fact bringing down inflation is costly presenting a challenge to the new keynesian model two departures from the new keynesian model predict costly disinflation one assumes sticky inflation rather than sticky prices while the other assumes less than perfectly rational expectations taking into account information from surveys of inflation expectations i find the evidence suggests that inflation is not sticky and that inflation expectations are less than perfectly rational

menu costs and the neutrality of money a model of endogenous price adjustment under money growth is presented firms follow s s pricing policies and price revisions are imperfectly synchronized in the aggregate price stickiness disappears and money is neutral the connection between firm price adjustment and relative price variability in the presence of monetary growth is also investigated the results contrast with those obtained in models with exogenous fixed timing of price adjustment

the un importance of forward looking behavior in price specifications the seminal work of edmund s phelps 1978 john b taylor 1980 and guillermo a calvo 1983 developed forward looking models of price determination that imparted inertia to the price level these models incorporate expectations of future prices and excess demand by imposing constraints typically lag lead symmetry constraints that force future variables to enter the specification in this paper the author tests the empirical significance of future prices in specifications like those of taylor he finds that expectations of future prices are empirically unimportant in explaining price and inflation behavior however the dynamics of a model that includes a purely backward looking inflation specification differ substantially and not altogether pleasingly from those with a forward looking specification copyright 1997 by ohio state university press

weak instrument robust tests in gmm and the new keynesian phillips curve we discuss weak instrument robust statistics in gmm for testing hypotheses on the full parameter vector or on subsets of the parameters we use these test procedures to reexamine the evidence on the new keynesian phillips curve model we find that u s postwar data are consistent with the view that inflation dynamics are predominantly forward looking but we cannot rule out the presence of considerable backward looking dynamics moreover the phillips curve has become flatter recently and this is an important factor contributing to its weak identification

economic expectations and voting behavior in united states house and senate elections past individual level studies of economic voting 1 have incorrectly operationalized the model they employ by using past oriented rather than future oriented questions and 2 have failed to examine the level of economic voting in united states senate elections using the 1978 national election study we show that economic voting exists in senate but not house elections presumably due to the differences in electoral context even when economic voting occurs however there is no guarantee that the public will influence the direction of macroeconomic policy

the political and economic origins of consumer confidence economic conditions the story usually goes influence consumer confidence which in turn influences both political evaluations and votes but we have little sense of the origins of consumer confidence itself it is generally assumed that monthly reports of the nation s level of consumer confidence respond to objective economic conditions we argue that politics is important for understanding consumer sentiment beyond what we know from economic conditions specifically we demonstrate a direct effect of political evaluations of the president s management of the economy the party of the president extraordinary political events and monetary policy as well as an indirect effect of media coverage of the economy on consumer sentiment after controlling for economic conditions when news coverage is positive citizens give favorable evaluations leading to more positive sentiment our findings suggest that understanding the political economy requires an emphasis on the causal effect of politics as well as economics

the utility maximizing self employed physician we estimate a model of utility maximizing physician behavior our model accounts for the interdependence of physician input output and work leisure choices and includes an endogenous virtual wage for physician own time in the medical practice we find that solo practitioners respond to increases in marginal hourly earnings and nonpractice income by allocating less time to medical practice activities our results also suggest that fee reductions induce the substitution of physician own time for auxiliaries and the net effect of this adjustment is reduced patient loads and a decrease in supply from the existing stock of solo practitioners

the market for physicians services theoretical implications and an empirical test of the target income hypothesis over the period 1965 to 1977 expenditure for health care in the united states increased from 181 per capita to 697 per capita the share of gnp composed of health care expenditures grew from 5 9 in 1965 to 8 8 in 1977 over this same period the number of physicians in the u s increased from 153 physicians per 100 000 population to 194 physicians per 100 000 such startling figures have generated much interest in the economics of health care with special concern about physician behavior and its effects upon health care costs the frequent empirical finding of a positive partial correlation between physicians fees or earnings and the number of physicians per capita have led many observers to eschew standard supply and demand models in favor of models that allow physicians themselves to significantly affect the demand for their services an assumption that physicians influence demand can not by itself differentiate a model from standard microeconomic models a profit maximizing doctor possessing costless demand shifting powers would shift demand to the greatest possible extent and then choose price and quantity to maximize profits subject to that shifted demand function a demand shifting model can yield results which are qualitatively different from those predicted by a standard model only with a behavioral assumption other than profit maximization the assumption of satisficing behavior on the part of physicians is a common substitute numerous empirical findings have been cited as evidence of the validity of the satisficing with demand shifting models much of this evidence however has been obtained as a by product of estimates of the demand for physician services rather than as the result of the estimation of a supply induced demand with satisficing model this lack

the labour supply behaviour of self employed solo practice physicians this paper investigates the empirical labour supply behaviour of self employed solo practice physicians the specification of the empirical labour supply equation is based on a model of constrained utility maximizing behaviour that recognizes the physician makes work leisure choices based on an endogenous shadow wage and faces a nonlinear budget constraint the findings suggest that the typical self employed solo practice male physician operates on the upward sloping portion of the labour supply curve and is relatively unresponsive to changes in marginal hourly medical practice earnings and non practice income

a near rational model of the business cycle with wage and price inertia this paper presents a model in which insignificantly suboptimal behavior causes aggregate demand shocks to have significant real effects the individual loss to agents with inertial price wage behavior is second order in terms of the parameter describing the shock while the effect on real economic variables is first order thus significant changes in business activity can be generated by anticipated money supply changes provided that some agents are willing to engage in nonmaximizing behavior which results in small losses

dynamic games and the time inconsistency of optimal policy in open economies it has been argued that the bretton woods system of pegged but adjustable exchange rates set up after world war ii was designed specifically to prevent the manipulation of exchange rates in pursuit of national macroeconomic objectives see r cooper so it is perhaps no coincidence that the ending of pegged rates has led to the re emergence of theories and policies involving such manipulation before the war when inflation was low and unemployment high in the major industrialised nations this involved competitive depreciation as countries tried to gain employment in the late 1970 s and early 1980 s however countries like the uk and the us have embarked on policies of competitive appreciation in order to cut inflation regarded as the first priority sharp movements in exchange rates however constitute a threat to orderly trade and stimulate protectionism as bergsten 1981 argues this abstract was borrowed from another version of this item

peasants or bankers the american electorate and the u s economy t he usual model of electoral reaction to economic conditions assumes the retrospective economic voter who bases expectations solely on recent economic performance or personal economic experience voter as peasant a second model assumes a sophisticated economic voter who incorporates new information about the future into personal economic expectations voter as banker using the components both retrospective and prospective of the index of consumer sentiment ics as intervening variables between economic conditions and approval we find that the prospective component fully accounts for the presidential approval time series with aggregate consumer expectations about long term business conditions in the approval equation neither the usual economic indicators not the other ics components matter moreover short term changes in consumer expectations respond more to current forecasts than to the current economy the qualitative result is a rational expectations outcome the electorate anticipates the economic future and rewards or punishes the president for economic events before they happen economics moves political behavior with hard times administrations lose support with good times they gain it we know this to be true but when we ask how by what processes the political translation of economic experience occurs the an

methods of estimation for models of markets with bounded price variation introduction there has been a considerable amount of literature on the estimation of models which are in disequilibrium see fair and jaffe 1972 fair and kelejian 1974 amemiya 1974 maddala and nelson 1974 goldfeld and quandt 1975 laffont and garcia 1977 bowden 1978 etc the main feature of these models is that there is a demand function a supply function a min condition and in some models a price adjustment equation the cornerstone equation in these models is q1 min d1 s where d t quantity demanded at time t s t quantity supplied at time t q t quantity transacted at time t this equation which says that the short side of the market always prevails separates the sample points into those belonging to demand and those belonging to supply one can classify the models into two categories those with sample separation known and those with sample separation unknown but the important point is that the min condition implies under the usual assumptions that the probability of equilibrium is zero for any t however there are many practical cases where some of the observations refer to equilibrium points and some to disequilibrium points this is because trading in many markets is confined to some limits on price and the disequilibrium occurs only when these limits are violated there are minimum wage laws in labor markets usury laws in credit markets and trading limits in commodity markets in all such cases the markets are sometimes in equilibrium and sometimes in disequilibrium the present paper discusses methods of estimation for models of such markets

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

it s all bad news voters perception of macroeconomic policy competence the purpose of the present paper is to consider how voters form perceptions about macroeconomic policy competence by focusing on the role of recent macroeconomic news do their perceived views of good news matter as much as bad news when they form beliefs about the incumbent government s competence in managing the macroeconomy in particular with regard to their ability to control inflation and unemployment we find that bad news about unemployment persists when households are forming their perceived competence whereas good news does not that is voters tend to display pessimistic bias when forming perceptions about the incumbent government s competence

imperfect credibility and inflation persistence in this paper we formulate a dynamic general equilibrium model with staggered nominal contracts in which households and rms use optimal ltering to disentangle persistent and transitory shifts in the monetary policy rule the calibrated model accounts quite well for the dynamics of output and insation during the volcker disinsation and implies a sacri ce ratio very close to the estimated value our approach indicates that insation persistence and substantial costs of disinsation can be generated in an optimizing agent framework without relaxing the assumption of rational expectations or relying on arbitrary modi cations to the aggregate supply relation jel classi cation e31 e32 e52

testing the rationality of price forecasts new evidence from panel data this paper tests the rationality of individual price forecasts in a panel of professional forecasters here unlike in most previous studies rationality is not rejected the results here differ because 1 using individual forecasts avoids aggregation bias 2 comparison of forecasts to initial data avoids bias due to data revision 3 the professional forecasters have economic incentives to state their expectations accurately and 4 a new covariance matrix estimator consistent when forecast errors are correlated across individuals is used copyright 1990 by american economic association

expectations and the effects of monetary policy this paper examines the predictive power of shifts in monetary policy as measured by changes in the real federal funds rate for output inflation and survey expectations of these variables we find that policy shifts have larger effects on actual output than on expected output thus policy predicts errors in output expectations a violation of rational expectations policy shifts do not predict errors in inflation expectations we explain these results with a model in which agents systematically underestimate the effects of policy on aggregate demand this model helps to explain the real effects of policy

identifying the new keynesian phillips curve phillips curves are central to discussions of inflation dynamics and monetary policy the hybrid new keynesian phillips curve nkpc describes how past inflation expected future inflation and a measure of real aggregate demand drive the current inflation rate this paper studies the potential weak identification of the nkpc under generalized method of moments and traces this syndrome to a lack of higher order dynamics in exogenous variables we employ analytic methods to understand the economics of the nkpc identification problem in the canonical three equation new keynesian model we revisit the empirical evidence for the usa the uk and canada by constructing tests and confidence intervals based on the anderson and rubin 1949 statistic which is robust to weak identification we also apply the guggenberger and smith 2008 lm test to the underlying nkpc pricing parameters both tests yield little evidence of forward looking inflation dynamics copyright 2008 john wiley sons ltd

macroeconomic expectations of households and professional forecasters economists have long emphasized the importance of expectations in determining macroeconomic outcomes yet there has been almost no recent effort to model actual empirical expectations data instead m acroeconomists usually simply assume that expectations are rational this paper shows that while empirical household expectations are not rational in the usual sense expectational dynamics are well captured by a model in which households views derive from news reports of the views of professional forecasters which in turn may be rational the model s estimates imply that people only occasionally pay attention to news reports this inattention generates stickyness in aggregate expectations with important macroeconomic consequences

limited asset markets participation monetary policy and inverted aggregate demand logic abstract this paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset market participation while moderate participation rates strengthen the role of monetary policy low enough participation causes an inversion of results dictated by conventional wisdom the slope of the is curve changes sign the taylor principle is inverted optimal welfare maximizing discretionary monetary policy requires a passive policy rule and the effects and propagation of shocks are changed however a targeting rule implementing optimal policy under commitment delivers equilibrium determinacy regardless of the degree of asset market participation our results may justify fed s behavior during the great inflation period

european inflation dynamics abstract we provide evidence on the fit of the new phillips curve npc for the euro area over the period 1970 1998 and use it as a tool to compare the characteristics of european inflation dynamics with those observed in the u s we also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs as well as that of its two main components namely labor productivity and real wages some of the findings can be summarized as follows a the npc fits euro area data very well possibly better than u s data b the degree of price stickiness implied by the estimates is substantial but in line with survey evidence and u s estimates c inflation dynamics in the euro area appear to have a stronger forward looking component i e less inertia than in the u s d labor market frictions as manifested in the behavior of the wage markup appear to have played a key role in shaping the behavior of marginal costs and consequently inflation in europe

heterogeneity in perceptions of national economic conditions empirical findings concerning economic voting differ according to the level of analysis employed a widely accepted explanation for the inconsistency between macroand microlevel evidence of economic voting is the high degree of random variation that plagues survey data according to this explanation aggregation purges individual level noise from mass opinions on policy issues and outcomes building on the research of bartels 1996 we debate the validity of this explanation by demonstrating that public evaluations of the national economy vary systematically with information media exposure political attitudes personal experiences and demographic characteristics furthermore we show that these sources of subjective heterogeneity produce systematic biases when national economic evaluations are aggregated these findings challenge a widely accepted notion that because error in individual level measures or expressions of preferences is random the aggregation of these individual measures ensures that they correctly represent the collective preference mpirical findings concerning the influence of the economy on political behavior differ depending on the level of analysis employed using aggregate level data numerous studies have established a statistical relationship between economic conditions and election outcomes or executive popularity e g kramer 1971 mackuen erikson and stimson 1992 on the basis of the macro level evidence alone one would have little reason to doubt that the economy matters in contrast individual level studies using survey data have produced only mixed evidence that voters consider economic conditions when evaluating the incumbent government and its leaders e g fiorina 1978 1981 kinder and kiewiet 1979 1981 moreover the strongest survey evidence of economic voting suggests that voters primarily care about national economic conditions not their personal financial situation this finding contradicts the egocentric theory posited by early macro level research that national economic indicators matter because they are correlated with personal financial circumstances the micro macro dichotomy in economic voting research reflects a similar dichotomy in research on voter sophistication and representation aggregate level studies tend to indicate that voters are reasonably well informed about the economy and make forward looking rather sophisticated voting decisions e g alesina londregan and rosenthal 1993 suzuki and chappell 1996 palmer and whitten 1999 these studies infer that mass political decisions conform to rational expectations or at least limited information rationality e g mackuen erikson and stimson 1992 in contrast to this macro level image of the voter individual level survey research has shown that the public in general has low levels of political sophistication lacking much knowledge of and interest in politics e g

whose expectations augment the phillips curve abstract this letter uses consumer survey data to estimate expectations augmented phillips curves with inflation expectations disaggregated by socioeconomic and demographic groups the inflation expectations of high income college educated male and working age people play a larger role in inflation dynamics than do the expectations of other groups of consumers or of professional forecasters

union wage settlements during a disinflation this paper examines the role of union wage contracts in the persistence of inflation and the implication of these contracts for the problem of disinflation in the united states a quantitative model of overlapping con tracts explicitly oriented toward the major union sector is developed the model takes account of expectations of future wage price and employment conditions as in more aggregated models that have been used in macroeconomic research in addition the distribution of workers according to contract length as well as deferred wage increases and escalator clauses are explicitly used in the model the main aim of the model is to determine the constraints which these contracts impose on disinflation paths the model indicates that the maximum speed of disinflation is extremely slow in the early phases if a rise in unemployment is to be avoided but increases considerably before the new lower rate of inflation is reached the disinflation path is considerably slower than that observed after hyperinflation periods however the existence of a path of inflation reduction raises questions about whether the institution of union wage con tracts is really the direct cause of costly disinflations or whether their influence works indirectly by raising credibility problems about a monetary disinflation this abstract was borrowed from another version of this item

robustness of the estimates of the hybrid new keynesian phillips curve abstract gali and gertler 1999 inflation dynamics a structural econometric approach journal of monetary eonomics 44 2 195 222 developed a hybrid variant of the new keynesian phillips curve that relates inflation to real marginal cost expected future inflation and lagged inflation gmm estimates of the model suggest that forward looking behavior is dominant the coefficient on expected future inflation substantially exceeds the coefficient on lagged inflation while the latter differs significantly from zero it is quantitatively modest several authors have suggested that our results are the product of specification bias or suspect estimation methods here we show that these claims are incorrect and that our results are robust to a variety of estimation procedures including gmm estimation of the closed form and nonlinear instrumental variables also as we discuss many others have obtained very similar results to ours using a systems approach including fiml techniques hence the conclusions of gg and others regarding the importance of forward looking behavior remain robust

fitting observed inflation expectations abstract the paper provides evidence on the extent to which inflation expectations generated by a standard christiano et al 2005 smets and wouters 2003 type dsge model are in line with what observed in the data we consider three variants of this model that differ in terms of the behavior of and the public s information on the central banks inflation target allegedly a key determinant of inflation expectations we find that i time variation in the inflation target is needed to capture the evolution of expectations during the post volcker period ii the variant where agents have imperfect information is strongly rejected by the data iii inflation expectations appear to contain information that is not present in the other series used in estimation and iv none of the models fully capture the dynamics of this variable

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

inflation dynamics and subjective expectations in the united states i introduction this paper analyzes the ability of sticky price models to explain the dynamics of u s inflation when using survey data as proxies for inflation expectations testing sticky price models with survey expectations is attractive since to the extent that survey data correctly capture agents expectations they allow to disregard issues related to the specification of agents expectations functions one neither has to impose untested orthogonality restrictions as required when estimating under the assumption of rational expectations nor has to make restrictive assumptions about the precise form of nonrationality present in agents forecast functions this allows to focus on the question whether the economic models under consideration are correctly specified previous tests of sticky price models performed under the assumption that agents hold rational expectations have generated mixed results prominently fuhrer and moore 1995 have reported that sticky price models do not generate sufficient stickiness for inflation when the output gap is used as a measure of real marginal costs recent evidence however has shown that the empirical performance depends crucially on how one measures real marginal costs the main determinant of inflation according to sticky price models for instance gall and gertler 1999 and sbordone 2002 show that sticky price models perform well once marginal costs are approximated by average unit labor costs 1 it makes an important difference whether sticky price models successfully explain inflation dynamics as a function of output behavior or they relate inflation dynamics to the behavior of unit labor costs given that the ultimate objective is a model explaining the joint behavior of output and inflation the latter case would require an additional empirically plausible theory linking the dynamics of unit labor costs to the behavior of output this paper studies whether the currently popular new keynesian phillips curve nkpc which can be derived from calvo 1983 style sticky price models is able to explain a relationship between inflation on the one hand and output or unit labor costs on the other hand thus we let the data speak whether a theory linking output to costs is warranted once expectations are approximated by data reported in the survey of professional forecasters our main finding is that the nkpc performs equally well with both measures of marginal costs output and unit labor costs whatever measure is used the estimate of the quarterly discount factor is close to one and the point estimate of the degree of price stickiness implies that firms reset their prices roughly every five quarters on average these results suggest that potential nonrationalities in expectations as they show up in surveys have biased previous estimates using output as a measure for marginal costs quite surprisingly the same nonrationalities do not seem to play a role when using unit labor costs here our estimates confirm the results obtained by gall and gertler 1999 and sbordone 2002 who assumed rational expectations we show that the reason for this finding is that approximating the agents information set using the unit labor cost variable rests on more solid grounds than approximating it using the output variable in particular the survey data suggest that the hypothesis of rational expectations implies a too high correlation between lagged output and future inflation expectations we show that this causes the coefficient estimate for output to become negative contrary to what is implied by theory these results suggest that once one takes account of potentially nonrational expectations via survey expectations sticky price models are able to establish a close link between output dynamics and the behavior of inflation to assess the robustness of this finding we include into the price equation lags of various variables and test for their significance

monetary policy rules and the indicator properties of asset prices abstract we investigate relationships between asset prices and inflation in a modern keynesian model in which monetary policy controls inflation by manipulating the federal funds rate the indicator properties of asset prices are quite sensitive to the monetary policy rule including the asset prices themselves in the reaction function can invert the sense of the indicator properties targeting the asset prices is tantamount to targeting the real interest rate when all of the weight in the reaction function is placed on asset prices the real rate converges so rapidly that policy loses control of inflation

what do economists know an empirical study of experts expectations for more than three decades economic columnist joseph a livingston has canvassed a panel of economists twice a year eliciting their six month and twelve month forecasts for more than a dozen key variables this study analyzes whether the experts predictions are unbiased and whether complete use was made of all relevant known information unbiasedness and completeness being necessary conditions for fully rational expectations little bias was found in either the half year or full year predictions but extensive underutilization of information particularly data on monetary growth occurred to prophecy is extremely difficult especially with respect to the future chinese proverb do economists expectations regarding key price and nonprice variables utilize all known relevant information in an unbiased efficient manner this is a worthy subject for research for several reasons properties of experts predictions likely form an upper bound for those of laymen further as john muth 14 has noted the character of dynamic processes is typically very sensitive to the way expectations are influenced by the actual course of events p 316 hence we need to know precisely how events do affect expectations finally the common practice of replacing a variable s generally unobserved expectation with a proxy based on its past values will be unbiased and will not cause bias in other

price inertia and policy ineffectiveness in the united states 1890 1980 this paper introduces a new approach to the empirical testing of the lucas sargent wallace lsw policy ineffectiveness proposition which compares the lsw hypothesis with an alternative that states that prices respond fully in the long run but only gradually in the short run to nominal aggregate demand disturbances the empirical equations estimated for a new set of quarterly data extending back to 1890 exhibit uniformly high responses of real output and low responses of price changes to anticipated changes in nominal gnp the paper compares and tests three alternative methods of introducing persistence effects into the lsw framework

tests of the rational expectations hypothesis this paper reviews evidence on the structure of anticipation from a number of empirical studies jack muth s rational expectations hypothesis is compared with a variety of alternative models including ferber s law the implicit expectations model of edwin mills and muth s new errors in the variables model the cumulative evidence is of such strength as to compel the suspension of belief in the concept of rational expectations this implies that it is a mistake to proceed under the maintained hypothesis that expectations are rational instead it is necessary to test the sensitivity of empirical and theoretical results to alternative assumptions about the structure by which anticipations are generated copyright 1986 by american economic association

the personal and political underpinnings of economic forecasts recently a great deal of attention has been focused on the impact of prospective evaluations of the economy on vote choice yet little attention has been focused on the actual process whereby such evaluations are formed this paper employs panel data to test a model of the formation of prospective evaluations of inflation and unemployment our findings indicate that retrospective assessments of economic conditions do not greatly influence economic forecasts instead economic forecasts are shaped by personal economic circumstances and partisan assessments of governmental performance the political implications of such findings are discussed

models of inflation expectations formation a comparison of household and economist forecasts comment in the third section of his paper models of inflation expectations formation a comparison of household and economist forecasts gramlich 1983 presents statistics suggesting that two survey measures of inflation expectations are biased and inefficient in this comment we show that the main results presented in his table 1 are generated using a misspecified model when the specification error is corrected we find that the michigan survey of household inflation expectations passes the standard tests for unbiasedness and weak tests for efficiency 1 however there remains doubt about the properties of the inflation expectation series derived from the livingston survey of professional economists 2 the particular results we review were presumably generated from ordinary leastsquares ols estimation of the following equation equation 2 in gramlich
