do macroforecasters herd we show that typical tests of whether forecasters herd will falsely indicate herding behaviour for a variety of types of behaviour and forecasting environments that give rise to disagreement amongst forecasters we establish that forecasters will appear to herd if di erences between them reject noise as opposed to private information or if they arise from informational rigidities noise can have a behavioural interpretation and if so will depend on the behavioural model under consideration an application of the herding tests to us quarterly survey forecasts of inflation and output growth data 1981 2013 does not support herding behaviour

implications of ethnic diversity ethnically differentiated societies are often regarded as dysfunctional with poor economic performance and a high risk of violent civil conflict the author distinguishes between dominance in which one group constitutes a majority and fractionalization in which there are many small groups in terms of overall economic performance the research shows that both theoretically and empirically fractionalization is normally unproblematic in democracies although it can be damaging in dictatorships in terms of the risk of civil war the author shows that both theoretically and empirically fractionalization actually makes societies safer while dominance increases the risk of conflict a policy implication is that fractionalized societies are viable and secession should be discouraged

information rigidities and the news adjusted output gap a vector autoregressive model of actual output and expected output obtained from surveys is used to test for information rigidities and to provide a characterisation of output dynamics that accommodates these information structures news on actual and expected outputs is decomposed to identify innovations understood to have short lived effects and these are used with the model to derive a news adjusted output gap measure the approach is applied to us data over 1970q1 2014q2 and the new gap measure is shown to provide a good leading indicator of inflation

imperfect information and the business cycle imperfect information has played a prominent role in modern business cycle theory this paper assesses its importance by estimating the new keynesian nk model under alternative informational assumptions one version focuses on confusion between temporary and persistent disturbances another on unobserved variation in the inflation target of the central bank a third on persistent mis perceptions of the state of the economy measurement error and a fourth assumes perfect information the standard nk dsge version imperfect information is found to contain considerable explanatory power for business fluctuations signal extraction seems to provide a conceptually satisfactory empirically plausible and quantitatively important business cycle mechanism

quantification and characteristics of household inflation expectations in switzerland inflation expectations are a key variable in conducting monetary policy however these expectations are generally unobservable and only certain proxy variables exist such as surveys on inflation expectations this article offers guidance on the appropriate quantification of household inflation expectations in the swiss consumer survey where answers are qualitative in nature we apply and evaluate different variants of the probability approach and the regression approach we demonstrate that models that include answers on perceived inflation and allow for time varying response thresholds yield the best results and we show why the originally proposed approach of fluri and sporndli 1987 has resulted in heavily biased inflation expectations since the mid 1990s furthermore we discuss some of the key features of swiss household inflation expectations i e the fact that there has been a shift in expectation formation since 2000 expectations are better anchored and less adaptive and there is lower disa

direct evidence on sticky information from the revision behavior of professional forecasters we provide direct evidence on the sticky information model of mankiw and reis 2002 by examining how frequently individual professional forecasters revise their forecasts we draw interest rate and unemployment rate forecasts from the monthly wall street journal surveys conducted between 2003 and 2013 consistent with the sticky information model we find that forecasters frequently leave their forecasts unrevised but find evidence that revision frequency increases following larger changes in the information set we also find revision frequencies became more sensitive to new information after the 2008 financial crisis but only weak evidence that frequent revisers forecast more accurately

tax aversion in labor supply abstract in a real effort laboratory experiment labor supply decreases more with the introduction of a tax than with a financially equivalent drop in wages this tax aversion is large in magnitude when we decompose the productivity decrease that arises from taxation we estimate that 40 is due to the lower net wage and the remaining 60 to tax aversion this tax aversion affects labor supply more on the extensive margin working less than on the intensive margin being less productive while working the aversion is equally strong whether tax revenue goes to the u s government or back to the experimenter a laboratory tax we discuss the implications of our results for the relationship between labor supply and taxation

stabilizing expectations at the zero lower bound experimental evidence abstract our study demonstrates how agents expectations can interact dynamically with monetary and fiscal policy at the zero lower bound we study expectation formation near the zero lower bound using a learning to forecast laboratory experiment under alternative policy regimes in our experimental economy monetary policy targets inflation around a constant or state dependent target we find that subjects expectations significantly over react to stochastic aggregate demand shocks and historical information leading many economies to experience severe deflationary traps neither quantitatively nor qualitatively communicating the state dependent inflation targets reduce the duration or severity of economic crises introducing anticipated and persistent fiscal stimulus at the zero lower bound reduces the severity of the recessions when the recovery of fundamentals is sufficiently slow participants expectations become highly pessimistic and neither monetary nor fiscal policy are effective at stabilizing the economy

sticky information phillips curves european evidence we estimate the sticky information phillips curve model of mankiw and reis 2002 using survey expectations of professional forecasters from four major european economies our estimates imply that in ation expectations in france germany and the united kingdom are updated about once a year in italy about once each six months

do people understand monetary policy abstract we combine questions from the michigan survey about future inflation unemployment and interest rates to investigate whether households are aware of the basic features of u s monetary policy our findings provide evidence that some households form their expectations in a way that is consistent with a taylor 1993 type rule we also document a large degree of variation in the pattern of responses over the business cycle in particular the negative relationship between unemployment and interest rates that is apparent in the data only shows up in households answers during periods of labor market weakness

does a shift in the tax burden create employment according to dalton s law it does not matter which side of the market is taxed this holds for a model of the labour market as well nevertheless it is often maintained that shifting the wedge from employers to employees has favourable effects on employment that is a shift from employers to employees taxes decreases wages and hence unemployment this apparent paradox is discussed by analysing the impact of taxes in a wage bargaining model it is shown that dalton s law does not necessarily hold in those models the findings are illustrated by empirical results concerning tax shifting by employers and employees for the netherlands it is found that no employers taxes are shifted backwards whereas about 44 of employees taxes are shifted forwards these values imply a positive effect on employment of a reduction of the wedge in favour of employers

can firms see into the future survey evidence from germany abstract this paper presents new evidence on the expectation formation process of firms from a survey of the german manufacturing sector first firms become too optimistic after their business has improved consistent with the over extrapolation of their experience second firms extrapolate improvements in their business more than deteriorations third firms are more optimistic pessimistic than usual during business cycle peaks troughs suggesting that they do not anticipate reversals fourth the german reunification provided a positive exogenous shock to the business of west german products the industries most positively affected by the shock initially over extrapolated the past downward trend just as much as the less affected industries and thus failed to anticipate the reversal fifth more overoptimistic firms subsequently report larger inventories and lower profits suggesting that expectation errors entail opportunity costs sixth older and larger firms show a smaller extrapolation bias indicating that time and resources can alleviate the extrapolation bias seventh firms that expect their business to improve tend to also expect their prices to increase suggesting that firms mostly try to forecast demand shocks as opposed to supply shocks overall these observations suggest that firms have a limited ability to anticipate changes in their activity and extrapolate their experience too much

union wage setting and unemployment in the netherlands 1965 1987 this paper presents an empirical model of union wage setting and employment the stackelberg equilibrium unemployment rate is shown to be a function of taxes the replacement ratio the gap between consumer and producer prices productivity effects and the rate of long term unemployment the model is estimated with aggregate data from the private sector in the netherlands 1965 1987 the results suggest that the equilibrium unemployment rate is pushed upwards by taxes the replacement ratio and by the gap between consumer and producer prices and is reduced by productivity effects insider outsider effects appear insignificant

learning from private and public observations of othersʼ actions we study how a continuum of agents learn about disseminated information by observing others actions every period each agent observes a public and private noisy signal centered around the aggregate action taken by the population the public signal represents an endogenous aggregate variable such as a price or a quantity the private signal represents the information gathered through private communication and local interactions we identify conditions such that the average learning curve is s shaped learning is slow initially intensifies rapidly and finally converges slowly to the truth we show that increasing public information always slows down learning in the long run and under some conditions reduces welfare lastly optimal diffusion of information requires that agents strive to be different agents need to be rewarded for choosing actions away from the population average

social classes and state behavior abstract van winden 1983 developed the interest function approach to the study of politico economic phenomena it starts from the familiar premise that economic agents have preferences with regard to the results of economic and political processes this paper develops a behavioral model with four classes of participants in the system and attempts to estimate the behavioral influences of these groups on the state

knowing what others know coordination motives in information acquisition we explore how optimal information choices change the predictions of strategic models when a large number of agents play a game with strategic complementarity information choices exhibit complementarity as well if an agent wants to do what others do they want to know what others know this makes heterogeneous beliefs di cult to sustain and may generate multiple equilibria in models with substitutability agents prefer to difierentiate their information choices we use these theoretical results to examine the role of information choice in recent price setting models and to propose modeling techniques that ensure equilibrium uniqueness

inattention in individual expectations abstract this paper investigates the expectations formation process of economic agents about inflation rate using the market expectations system of central bank of brazil we perceive that agents do not update their forecasts every period and that even agents who update disagree in their predictions we then focus on the two most popular types of inattention models that have been discussed in the recent literature sticky information and noisy information models estimating a hybrid model we find that although formally fitting the brazilian data it happens at the cost of a much higher degree of information rigidity than observed

aggregate fluctuations and international migration this paper studies the role of short run factors such as business cycles or changes in employment rates in explaining international migration flows we first derive a model of optimal migration choice predicting that short run economic fluctuations may trigger migration flows on top of the impact exerted by long run factors second we empirically test the magnitude of the effect of these short run factors on migration flows our results indicate that aggregate fluctuations and employment rates both affect migration flows third we provide evidence that the schengen agreement and the euro significantly raised the international mobility of workers between the member countries this article is protected by copyright all rights reserved

towards micropolitical foundations of public finance abstract observed fiscal policy reflects the incentives embedded in political institutions in this paper we illustrate the effects of two general institutional features separation of powers which is common in presidential congressional political systems and legislative cohesion which is typical of parliamentary systems compared to a simple legislative game separation of powers brings about a smaller size of government and lower waste legislative cohesion induces a more equal distribution but more waste and higher taxes than separation of powers

how do firms form their expectations new survey evidence author s coibion o gorodnichenko y kumar s abstract 2018 american economic association all rights reserved we survey new zealand firms and document novel facts about their macroeconomic beliefs there is widespread dispersion in beliefs about past and future macroeconomic conditions especially inflation this dispersion in beliefs is consistent with firms incentives to collect and process information using experimental methods we find that firms update their beliefs in a bayesian manner when presented with new information about the economy and that changes in their beliefs affect their decisions inflation is not generally perceived as being important to business decisions so firms devote few resources to collecting and processing information about inflation

information rigidity and the expectations formation process a simple framework and new facts we propose a new approach to test the full information rational expectations hypothesis which can identify whether rejections of the null arise from irrationality or limited information this approach quantifies the economic significance of departures from the null by quantifying the underlying degree of information rigidity applying this approach to u s and international data of professional forecasters and other agents yields pervasive evidence consistent with models of imperfect information furthermore the proposed approach sheds new light on policies such as inflation targeting and those leading to the great moderation affecting expectations finally we document evidence of state dependence in the expectations formation process

resistance to reform status quo bias in the presence of individual specific uncertainty comment why do governments so often fail to adopt policies which economists consider to be efficiency enhancing our answer to this question relies on uncertainty regarding the distribution of gains and losses from reform we show that there is a bias towards the status quo and hence against efficiency enhancing reforms whenever some of the individual gainers and losers from reform cannot be identified beforehand there are reforms which once adopted will receive adequate political support but would have failed to carry the day ex ante the argument does not rely on risk aversion irrationality or hysteresis due to sunk costs jel d72 f13 why do governments so often fail to adopt policies that economists consider to be efficiency enhancing this is one of the fundamental questions of political economy the answer usually relies on what may be

productivity growth consumer confidence and the business cycle abstract the objective of this paper is to provide in the context of a dynamic general equilibrium model an answer to the following five questions 1 to what extent does an economy subject to regular variations in labor productivity growth differ from one where labor productivity is constant 2 what is the impact on major macro indicators of a one time change in labor productivity growth 3 what are the business cycle implications of autonomous non falsifiable changes in growth expectations 4 what is the potential of such expectation changes for explaining the volatility of consumption to output ratio 5 can autonomous changes in growth expectations help us understand recent business cycle episodes

a quantitative comparison of sticky price and sticky information models of price setting i estimate sticky price and sticky information models of price setting for the united states via maximum likelihood techniques reaching several conclusions first the sticky price model fits best and captures inflation dynamics as well as reduced form equations once hybrid behavior is allowed second the importance of hybrid behavior in sticky price models is potentially consistent with a role for some information imperfections such as sticky information as a complement to nominal price rigidities finally the favorable results herein for the hybrid sticky price model when evaluated by statistics that summarize the relative fit of different models is consistent with the existing literature that is both supportive and dismissive of such models as this literature has largely ignored fit in evaluating such models many previous studies have focused on ancillary issues such as the standard errors associated with certain parameters or granger causality tests that may not provide much information about sticky price models

the applicability of the traditional theory of economic policy abstract the traditional theory of economic policy requires targets instruments an empirical economic model and a social welfare or criterion function to be specified in order to derive the optimal economic policy empirical studies of reaction functions suggest that economic policy is carried out in some systematic manner subject to interference from political factors this survey addresses the problems of specifying estimating and applying an economic model when economic policy is following a path specified by a reaction function attention is paid to rational expectations the lucas critique and the policy neutrality proposition lack of knowledge of the policy maker s objective function poses the most serious difficulty when applying the theory of economic policy various methods of determining this function are reviewed and the possibility that policy makers might be satisficing is discussed the role played by political factors is considered in the light of the public choice literature

information rigidities and exchange rate expectations abstract sluggish adjustment of expectations to new information is rational in an environment characterized by information costs and signal to noise problems this paper investigates the role of such information rigidities for exchange rate expectations using data from consensus economics for ten emerging and industrial economies from 1999 until 2015 our results confirm the importance of rigidities and show that the inclusion of forecast updates largely accounts for otherwise detected biases in expectation errors moreover we find little evidence for a systematic effect of fundamentals or uncertainty measures on exchange rate disagreement

a multivariate analysis of forecast disagreement confronting models of disagreement with survey data abstract this paper documents multivariate forecast disagreement among professional forecasters and discusses implications for models of heterogeneous expectation formation disagreement varies over time and is positively correlated with general economic uncertainty the degree to which individual forecasters disagree with the average forecast tends to persist over time models of heterogeneous expectation formation can be modified by introducing heterogeneous signal to noise ratios to match this feature furthermore disagreement about correlations of different macroeconomic variables is high on average in general multivariate forecast data can be used more effectively than it has been to estimate models with heterogeneous expectations and to test the mechanisms used to generate disagreement in these models

sticky information and sticky prices abstract in the u s and europe prices change at least once a year yet nominal macro shocks seem to have real effects lasting well beyond a year sticky information models as posited by mankiw and reis 2002 sticky information versus sticky prices a proposal to replace the new keynesian phillips curve quarterly journal of economics 117 1295 1328 sims 2003 implications of rational inattention journal of monetary economics 50 3 665 690 and woodford 2003 princeton university press princeton nj can reconcile micro flexibility with macro rigidity we simulate a sticky information model in which price setters update information on macro shocks less frequently than information on micro shocks we then examine price changes in the micro data underlying the u s cpi empirical price changes react to old information just as sticky information models predict

when is sticky information more information this paper uses sectoral data to study survey based balance indices designed to capture changes in the business cycle in real time the empirical framework recognizes that when answering survey questions regarding their firm s output respondents potentially rely on infrequently updated information the analysis then suggests that their answers reflect notable information lags on the order of 71 2 months on average moreover information stickiness implies that noisy output fluctuations will be attenuated in survey answers and consequently helps explain why balance indices successfully track business cycles conversely in an environment populated by fully informed identical firms as in the standard rbc framework for example balance indices instead become degenerate finally information regarding changes in aggregate output tends to be sectorally concentrated the paper therefore illustrates how this feature of the data may be relevant for the construction of balance indices

the role of central bank transparency for guiding private sector forecasts central banks have become remarkably more transparent over the last few decades in this paper we study the effects of this evolution focusing on whether enhanced central bank transparency lowers dispersion among professional forecasters of key economic variables we use a large set of proxies for central bank transparency in 12 advanced economies we find evidence for a sizeable effect e g by announcing a quantified inflation objective or by publishing inflation and output forecasts however there are decreasing marginal effects to increases in transparency and the disagreement among the expectations of the general public is not affected this suggests that there are possible limits to transparency

monetary neutrality under evolutionary dominance of bounded rationality i introduction a key property of the dynamic relationship between money and output is that due to price stickiness monetary shocks have persistent although not permanent impacts on the real output see e g christiano eichenbaum and evans 1999 the nominal adjustment of the aggregate price level in response to a monetary shock is therefore temporarily incomplete and considerable supporting empirical evidence for price rigidity has been found in several microprice studies see e g nakamura and steinsson 2013 and klenow and malin 2011 for comprehensive discussions of these studies mankiw and reis 2002 develop a novel model of temporarily incomplete nominal adjustment based on the assumption that costly information disseminates slowly in each period a random fraction of the price setters updates itself on the state of the economy so as to compute and set the optimal price while the remaining fraction keeps setting prices based on outdated information they admit that micro foundations for price stickiness may require a better understanding of bounded rationality and that information processing is more complex than the time contingent adjustment assumed in their paper in fact as added in mankiw and reis 2011 while the cost of acquiring information may be small and may even have fallen in this information age the costs of absorbing and processing information may be rather large and actually higher today than those in the past this paper contributes to the intuition on price setting under bounded rationality by developing a model in which the share of firms that have up to date information on relative prices to establish the optimal price follows evolutionary dynamics with and without mutation and not a random dynamics a la calvo 1983 as in mankiw and reis 2002 and the related literature our aim is to devise evolutionary game theoretic dynamics to provide alternative microfoundations for a temporarily incomplete nominal adjustment following a monetary shock we investigate the behavior of the general price level in an economy in which an individual firm can either pay a cost featuring a random component to update its information set and establish the optimal price nash strategy or freely use full information from the previous period and set a one period lagged optimal price bounded rationality strategy indeed detailed empirical studies such as the investigation for the euro zone by alvarez et al 2006 have found persistent coexistence of forward looking and backward looking price setting behavior and there is also robust empirical evidence showing persistent and time varying heterogeneity both in the frequency and in the extent of information updating see e g branch 2007 coibion and gorodnichenko 2012 we then devise evolutionary game theoretic microdynamics in discrete time that by interacting with the dynamics of the macroeconomic variables affects the coevolution of the frequency distribution of information updating strategies across firms and the completeness of the nominal adjustment of the general price level to a monetary shock our model economy is composed of monopolistically competitive firms whose individual optimal price depends positively upon the prices set by others implying the existence of strategic complementarity in a given period there is a fraction of firms that set prices without perfect knowledge of the structure of relative prices and hence of the prices that other firms will be setting as they decide not to pay the information cost involved in knowing it we refer to these firms as boundedly rational firms the remaining fraction is composed of firms that decide to incur the information updating cost to obtain that perfect knowledge and we follow droste hommes and tuinstra 2002 in referring to them as nash firms as they become perfect foresight firms meanwhile the optimal price is assumed to be given as in ball and romer 1991 varying positively with the actual general price level and nominal stock of money which is publicly known

the non equivalence of labour market taxes a real effort experiment under full rationality a labour market tax levied on employers and a corresponding income tax levied on employees are equivalent with boundedly rational agents this equivalence is no longer obvious in a real effort experiment we study the effects of these taxes on preferences concerning the size of the public sector subjective well being labour supply and on the job performance our findings suggest that employer side taxes induce preferences for a larger public sector subjective well being is higher under employer side taxes while labour supply is lower at least at the extensive margin we discuss three mechanisms that may underlie these results

can households see into the future survey evidence from the netherlands abstract this paper presents new evidence on the expectation formation process from a dutch household survey households become too optimistic about their future income after their income has improved consistent with the overextrapolation of their experience we show that this effect of experience is persistent and that households overextrapolate income losses more than income gains furthermore older households overextrapolate more suggesting that they did not learn over time to form more accurate expectations finally we study the relationship between expectation errors and consumption we find that more overoptimistic households intend to consume more and subsequently report higher consumption even though they do not consume as much as they intended to these results suggest that overextrapolation hurts consumers and amplifies business cycles

why do forecasters disagree lessons from the term structure of cross sectional dispersion abstract key sources of disagreement among economic forecasters are identified by using data on cross sectional dispersion in forecasters long and short run predictions of macroeconomic variables dispersion among forecasters is highest at long horizons where private information is of limited value and lower at short forecast horizons moreover differences in views persist through time such differences in opinion cannot be explained by differences in information sets our results indicate they stem from heterogeneity in priors or models differences in opinion move countercyclically with heterogeneity being strongest during recessions where forecasters appear to place greater weight on their prior beliefs

fomc forecasts as a focal point for private expectations we explore empirically the theoretical prediction that public information acts as a focal point in the context of the u s monetary policy we aim at establishing whether the publication of federal open market committee fomc inflation forecasts affects the cross sectional dispersion of private inflation expectations our main finding is that publishing fomc inflation forecasts has a negative effect on the cross sectional dispersion of private current year inflation forecasts this effect is found to be robust to another survey data set and to various macroeconomic controls moreover we find that the dispersion of private inflation forecasts is not affected by the dispersion of views among fomc members

hourly wages and working time in the dutch market sector 1962 1995 this article analyses the joint behaviour of hourly wages and standard hours in the netherlands with respect to the development of full time hours to different hypotheses are suggested work sharing or productivity sharing under the work sharing hypothesis high unemployment would lead to reduced hours whereas under productivity sharing increased productivity leads to higher wages or reduced hours the evidence is in favour of the productivity hypothesis there is no direct impact of unemployment on the evolution of hours moreover although reduced hours tend to increase hourly wages in the short run this is not the case in the long run

expectation formation following large unexpected shocks abstract by matching a large database of individual macroforecaster data with the universe of sizable natural disasters across 54 countries we identify a set of new stylized facts forecasters are

the effect of gnp announcements on fluctuations of gnp growth abstract this paper is an empirical study of the degree in which perceptions affect the evolution of the economy we study the effects of the announcements that the government makes on gnp growth these announcements are subject to a substantial degree of noise and its accuracy improves with time a revised number is published several years after the first announcement was made public we consider that the final revision is the true value of gnp growth we show that once announcements are taken into account the true value of gnp growth at time t has no predictive power in determining growth at any future time all the predictive power lies in the announcements and not in the true level of growth actually we show that the variable that determines future growth is the unexpected part of the announcements we also show that announcements affect growth via aggregate investment

what can survey forecasts tell us about information rigidities a lot we derive common and conflicting predictions from models in which agents face information constraints and then assess their validity using surveys of consumers firms central bankers and professional forecasters we document that mean forecasts fail to completely adjust on impact to shocks leading to statistically and economically significant deviations from the null of full information the dynamics of forecast errors after shocks are consistent with the predictions of models with information rigidities the conditional responses of forecast errors and disagreement among agents can also be used to differentiate between some of the most prominent models of information rigidities

benefits and unemployment in an open economy an equilibrium analysis this paper examines the relation between uemployment compensation and unemployment in the netherlands this relation is studied by menas of a small macroeconomic model for an open economy that assumes equilibrium in the labour market and on the current account the model yields an elasticity of unemployment to benefits of 1 0 which is high compared to microeconomic research and the outcomes of disequilibrium models for the netherlands according to the model a rise in the wedge i e the difference betweenn real labour cost and real net wages leads to an increase in unemployment whilst shifting this wedge from the employers to the employees induces a fall in unemployment

inattentive professional forecasters abstract using the ecb survey of professional forecasters to characterize expectations at the micro level we emphasize two new facts forecasters i fail to systematically update their forecasts and ii disagree even when updating it is moreover found that forecasters have predictable forecast errors these facts are qualitatively supportive of recent models of inattention and suggest a setup where agents imperfectly process information due to both sticky information a la mankiw reis and noisy information a la sims however building and estimating such an expectation model we find that it cannot quantitatively replicate the error and disagreement observed in the data

firms and aggregate dynamics abstract we investigate the role of permanent and transitory shocks for firms and aggregate dynamics we find that permanent shocks to productivity and permanent shifts in the composition of output explain at least four fifths of firms dynamics however these permanent shocks are almost uncorrelated across firms and are therefore less relevant for aggregate dynamics transitory shocks on the other hand are not very important at the firm level but they account for most of the volatility of aggregate hours and output because they are significantly correlated across firms finally we try to make some progress on the interpretation of the shocks

updating inflation expectations evidence from micro data utilizing the michigan household consumer survey s rotating panel microstructure we can identify if individuals have adjusted their expectations towards inflation this allows us to directly capture the updating behavior of individual consumers regarding their short and long run inflation expectations

the price is right updating inflation expectations in a randomized price information experiment abstract using a unique randomized information experiment embedded in a survey this paper investigates how consumers inflation expectations respond to new information we find that respondents on average update their expectations in response to certain types of information and do so sensibly in a manner consistent with bayesian updating as a result of information provision the distribution of inflation expectations converges toward its center and cross sectional disagreement declines we document heterogeneous information processing by gender and present suggestive evidence of respondents forecasting under asymmetric loss our results provide support for expectation formation models in which agents form expectations rationally but face information constraints

the macroeconomic tradeoffs of price and income policies under some conditions price and income policies may succeed in reaching the objective they pursue but in all cases tradeoffs place limits on what they can achieve these tradeoffs are discussed for three kinds of objectives reducing inequalities solving the inflation unemployment dilemma and restoring business profitability the uncertainties particularly the relationship between wages and employment are emphasized copyright 1990 by the editors of the scandinavian journal of economics

testing the sticky information phillips curve abstract i consider the empirical evidence for the sticky information model relative to the basic sticky price model conditional on historical measures of inflation forecasts the estimated structural parameters are inconsistent with an underlying sticky information model and the sticky information phillips curve is statistically dominated by the new keynesian phillips curve i find that the poor performance of the sticky information approach is driven by two key elements first the sticky information model underestimates inflation in the 1970s and overestimates inflation since the 1980s second predicted inflation from the sticky information model is excessively smooth

forecasting the forecasts of others implications for asset pricing we develop a dynamic asset pricing model with heterogeneously informed agents unlike previous research we focus on the general case where differential information leads to the problem of forecasting the forecasts of others and to non trivial dynamics of higher order expectations in particular we prove that the model does not admit a finite number of state variables using numerical analysis we compare equilibria characterized by identical fundamentals but different information structure we demonstrate that the distribution of information has substantial impact on equilibrium prices and returns in particular we show that asymmetric information can generate momentum in returns and high trading volume

rational expectations and macroeconomic forecasts the article presents extensive results from testing for bias and serially correlated errors in a collection of time series of quarterly multiperiod forecasts for six variables including real gnp growth inflation and unemployment the analysis covers responses by 79 frequent participants in economic outlook surveys conducted regularly since 1968 it shows much greater incidence of apparently systematic errors for inflation than for the other variables also the tests are more favorable to composite group forecasts than to most of the individual forecast sets

a traditional interpretation of macroeconomic fluctuations under the traditional interpretation of macroeconomic fluctuations aggregate demand shocks move output and prices in the same direction while aggregate supply shocks move output and prices in opposite directions this paper examines the joint behavior of u s output unemployment prices wages and nominal money and asks whether it is consistent with this interpretation the answer is a qualified yes

on the optimal monetary policy response to noisy indicators abstract we describe a behavior of a central bank when its measures of current inflation and output are subject to measurement errors in a framework of optimizing models with nominal price stickiness in our model a central bank sets the interest rate equal to its current estimate of the so called wicksellian natural rate of interest this is shown to imply that the interest rate responds to the central bank s estimates of both current inflation and output gap as advocated by taylor 1993 it is also shown that the noise contained in the indicators justifies a degree of policy cautiousness a reduced form representation of optimal policy should exhibit interest rate smoothing which is often found in the empirical literature on monetary policy reaction functions

how well does the is lm model fit postwar u s data postwar u s time series for money interest rates prices and gnp are characterized by a multivariate process driven by four exogenous disturbances those disturbances are identified so that they can be interpreted as the four main sources of fluctuations found in the is lm phillips curve model money supply money demand is and aggregate supply shocks the dynamic properties of the estimated model are analyzed and shown to match most of the stylized predictions of the model the estimated decomposition is also used to measure the relative importance of each shock to interpret some macroeconomic episodes and to study sources of permanent shocks to nominal variables

government purchases reloaded informational insufficiency and heterogeneity in fiscal vars using a large bayesian var we approximate the flow of information received by economic agents to investigate the effects of changes to government purchases we document robust evidence that informational insufficiency in conventional models explains inconsistent results across samples and commonly employed identifications in recursive structural vars and expectational vars furthermore we report heterogeneous effects of components of government purchases while aggregate government purchases do not appear to produce strong stimulative effects with output multiplier around 0 7 government investment components have multipliers well above unity state and local consumption which captures investment in education and health elicits a strong response

the role of uncertainty sentiment and cross country interactions in g7 output dynamics output fluctuations in the g7 are characterised using a var model of countries actual and expected outputs and uncertainty over these new measures are developed to quantify the relative importance of economic prospects versus uncertainty global versus national effects and fundamentals versus sentiment for countries persistent output movements national and global contributions are found to be equally important across the g7 although considerable differences exist between countries uncertainty and especially cross country uncertainty is important in propagating the effects of shocks and generates around 20 of countries persistent output movements on average fundamentals dominate output movements although with an 80 20 split sentiment plays a non negligible role

towards a politico economic theory of social security social security which will be taken here in its wide european sense not only encompassing public pension schemes but also other income transfers such as to unemployed sick and disabled persons and to widows and orphans nowadays figures large among government outlays after its continuous and fast expansion over especially the past two decades see e g saunders and klau 1985 and table 0 1 accordingly social security is receiving increasing attention in the economic profession recent discussions have focused on the effects of social security on capital accumulation and on its ability to achieve a more desirable distribution of income in these studies social security programs are typically treated as exogenously determined little attention has hitherto been paid to the explanation of social security policies

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

when are gdp forecasts updated evidence from a large international panel based on a large international panel of surveyed gdp forecasts i analyze the frequency of forecast revisions and the factors that influence the likelihood of forecast revisions i find that each month on average 40 50 of forecasters revise their forecasts in addition i find that the likelihood of forecast revisions significantly depends on a number of factors such as the forecast horizon the business cycle or strategic interactions between forecasters my results suggest that a realistic modeling of expectations forecasts of agents has to take into account cross sectional heterogeneity strategic interaction between agents and effects of the economic environment features that existing models such as the sticky information framework are missing

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

signals from the government policy disagreement and the transmission of fiscal shocks we investigate the effects of fiscal policy communication on the propagation of government spending shocks to this aim we propose a new index measuring the coordination effects of policy communication on private agents expectations this index is based on the disagreement amongst us professional forecasters about future government spending the underlying intuition is that a clear fiscal policy communication can coalesce expectations reducing disagreement results indicate that in times of low disagreement the output response to fiscal spending innovations is positive and large mainly due to private investment response conversely periods of elevated disagreement are characterised by muted output response

optimal price setting with observation and menu costs we study the price setting problem of a firm in the presence of both observation and menu costs in this problem the firm optimally decides when to collect costly information on the adequacy of its price an activity which we refer to as a price review upon each review the firm chooses whether to adjust its price subject to a menu cost and when to conduct the next price review this behavior is consistent with recent survey evidence documenting that firms revise prices infrequently and that only a few price revisions yield a price adjustment the goal of the paper is to study how the firm s choices map into several observable statistics depending on the level and relative magnitude of the observation vs the menu cost the observable statistics are the frequency of price reviews the frequency of price adjustments the size distribution of price adjustments and the shape of the hazard rate of price adjustments we provide an analytical characterization of the firm s decisions and a mapping from the structural parameters to the observable statistics we compare these statistics with the ones obtained for the models with only one type of cost the predictions of the model can with suitable data be used to quantify the importance of the menu cost vs the information cost we also consider a version of the model where several price adjustment are allowed between observations a form of price plans or indexation we find that no indexation is optimal for small inflation rates

european central bank footprints on inflation forecast uncertainty the finding of the paper shows the relative effectiveness of the one size fits all policy of the european central bank the paper provides strong evidence in favor of this by testing whether the monetary policy effects footprints found in inflation uncertainty converge to a common level these footprints are measured as the fraction of the estimated policy induced reduction in this uncertainty the testing was conducted by applying a bootstrap type test in a regression of the rate of growth of these fractions on their initial values computed for 16 euro area countries jel c33 e52 e58

a theory of demand shocks this paper presents a model of business cycles driven by shocks to consumer expectations regarding aggregate productivity agents are hit by heterogeneous productivity shocks they observe their own productivity and a noisy public signal regarding aggregate productivity the public signal gives rise to noise shocks which have the features of aggregate demand shocks they increase output employment and inflation in the short run and have no effects in the long run numerical examples suggest that the model can generate sizable equilibrium dsge models of the business cycle include a large number of shocks to technol ogy monetary policy preferences etc but typically do not include expectational shocks as independent drivers of short run fluctuations 1 this paper explores the idea of expectation driven cycles looking at a model where technology determines equilibrium output in the long run and consumers receive noisy signals about technology in the short run the presence of noisy signals produces expectational errors this paper studies the role of these expectational errors in gener ating volatility at business cycle frequencies the model is based on two ingredients first consumers take time to recognize permanent changes in aggregate fundamentals although they may have good information on the current state of the individual firm or sector where they operate they have only limited information regarding the long run determinants of aggregate activity second consumers have access to public information that is relevant to estimate long run productivity this includes news about technological innovations publicly released macroeconomic and sectoral statistics financial market prices and public statements by policy makers however these signals provide only a noisy forecast of the long run effects of technological innovations this opens the door to noise shocks which induce consumers to temporarily overestimate or underestimate the productive capacity of the economy

beauty contests and iterated expectations in asset markets in a financial market where traders are risk averse and short lived and prices are noisy asset prices today depend on the average expectation today of tomorrow s price thus iterating this relationship the date 1 price equals the date 1 average expectation of the date 2 average expectation of the date 3 price this will not in general equal the date 1 average expectation of the date 3 price we show how this failure of the law of iterated expectations for average belief can help understand the role of higher order beliefs in a fully rational asset pricing model and explain over reaction to noisy public information

information animal spirits and the meaning of innovations in consumer confidence we show that unexplained innovations in several variables representing survey responses to forwardlooking questions on the michigan survey of consumers have powerful prognostic implications for the future paths of macroeconomic variables we attempt to distinguish the hypothesis that these impulse responses indicate a causal channel from autonomous movements in sentiment to economic outcomes the animal spirits view from the alternative interpretation that the surprise confidence movements summarize information about future economic prospects the information view in natural rate models animal spirits shocks are associated with overshooting of among other variables consumption that attenuates when agents come to grips with their overreaction while information shocks about the long future are followed by gradual movements in macroeconomic variables that are not subsequently reversed in a baseline vector autoregression involving consumption income and confidence the data come down sharply in favor of the information view the impulse responses of consumption and gdp show no tendency to attenuate even after a number of years further confidence innovations have strong implications for labor productivity many quarters into the future in somewhat larger vars with an information block that includes inflation and or stock prices the impulse responses to confidence innovations continue to have the permanent shape that defines information shocks but they are smaller in magnitude we demonstrate that this is due to the fact that both inflation and stock price innovations have prognostic implications for future productivity that are very similar to the implications of innovations in confidence addition of unemployment to the system induces a transitory component that changes the shape of the impulse responses and somewhat weakens the previously airtight case against animal spirits but it does not provide constructive evidence of such effects

information rigidities in survey data evidence from dispersions in forecasts and forecast revisions abstract predictable forecast errors in survey data documented in the existing literature suggest a deviation from the rational expectations hypothesis and are in favor of imperfect information models such as sticky and noisy information models this article assesses the validity of the imperfect information models by establishing a linkage between dispersions in survey forecasts and survey forecast revisions we find that the dynamics of dispersion in survey forecasts are consistent with the prediction of sticky information models but at odds with that of conventional noisy information models as well as full information rational expectations models both of which assume agents continuous updating of their information sets

inflation expectations and monetary policy surprises we use monthly data across fifteen euro area economies for the period 1985 1 2015 3 to obtain monetary policy changes that can be regarded as surprises for different types of consumers a novel feature of our empirical approach is the estimation of monetary policy surprises based on changes in monetary policy that were unanticipated according to the consumers stated beliefs about the economy we go on to investigate how these monetary policy surprises affect consumers inflation expectations we find that such monetary policy surprises can have the opposite impact on inflation expectations to those obtained under the assumption that consumers are well informed about a set of macroeconomic variables describing the state of the economy more specifically when we relax the assumption of well informed consumers by focusing instead on their stated beliefs about the economy unanticipated increases in the interest rate raise inflation expectations this is consistent with imperfect information theoretical settings where unanticipated increases in interest rates are interpreted as positive news about the state of the economy by consumers that know policymakers have relatively more information this impact changes sign since the crisis

a structural var approach on labour taxation policies this paper presents a structural var analysis on the employment and output effects of labour tax policies in six european countries for the period 1974 1997 by considering impulse response functions it turns out that on average a shock to the total personal income tax revenues is positively correlated to employment whereas there is mixed evidence on the output effect moreover the quantitative impact of these effects especially those related to the output appears to be quite small however by introducing explicitly four labour tax parameters namely the marginal and average tax rates for the personal income tax and the payroll tax it turns out that these effects are not negligible after all for some countries it is possible to conceive labour taxes as policy instruments favouring more employment and a better economic performance however the empirical support on the sign of the output and employment effects is mixed suggesting that the same domestic fiscal policy does not produce the same im

the macroeconomic effects of false announcements suppose that the government were to announce the economy will be booming in six months and this announcement is based on false data what effect would such an announcement have on future aggregate activity this paper employs revisions of the series of leading economic indicators to test the hypothesis that such an announcement would have a positive effect on future activity we find that the evidence is generally consistent with the hypothesis and that for the time period 1976 1988 the expectational shocks measured by these revisions explain over 20 percent of the fluctuation in the quarterly growth rate of industrial production

the myth of incomes policy in the netherlands an assessment is made about whether the dutch government conducted an effective incomes policy in the postwar period targeted wage rate development is compared with actual wage outcomes and an empirical model of wage formation is used to estimate whether wage rates were lower when the incomes policy was on it is concluded that two periods of incomes policy were effective 1955 1959 and 1980 1981 however the net effect of the policy in 1955 1959 was very moderate due to a wage explosion in 1964

optimal sticky prices under rational inattention this paper presents a model in which price setting firms decide what to pay attention to subject to a constraint on information flow when idiosyncratic conditions are more variable or more important than aggregate conditions firms pay more attention to idiosyncratic conditions than to aggregate conditions when we calibrate the model to match the large average absolute size of price changes observed in micro data prices react fast and by large amounts to idiosyncratic shocks but only slowly and by small amounts to nominal shocks nominal shocks have strong and persistent real effects we use the model to investigate how the optimal allocation of attention and the dynamics of prices depend on the firms environment jel e 3 e5 d8

perceived inflation persistence this article constructs and estimates a measure called perceived inflation persistence that can be used to determine if professional forecasters inflation forecasts indicate there has been a change in inflation persistence this measure is built via the implied autocorrelation function that follows from the estimates obtained using a forecaster specific state space model findings indicate that u s perceived inflation persistence has changed since the mid 1990s with more consensus among forecasters at lower levels of persistence when compared to the autocorrelation function for actual inflation forecasters typically react less to shocks to inflation than the actual inflation data would suggest

sticky information and model uncertainty in survey data on inflation expectations abstract this paper compares three reduced form models of heterogeneity in survey inflation expectations on the one hand we specify two models of forecasting inflation based on limited information flows of the type developed in mankiw and reis 2002 sticky information versus sticky prices a proposal to replace the new keynesian phillips curve quarterly journal of economics 117 4 1295 1328 we present maximum likelihood results that suggests a sticky information model with a time varying distribution structure is consistent with the michigan survey of inflation expectations we also compare these sticky information models to the endogenous model uncertainty approach in branch 2004 the theory of rationally heterogeneous expectations evidence from survey data on inflation expectations economic journal 114 497 non parametric evidence suggests that models which allow the degree of heterogeneity to change over time provide a better fit of the data

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

optimal monetary policy with uncertain fundamentals and dispersed information this paper studies optimal monetary policy in a model where aggregate fluctuations are driven by the private sector s uncertainty about the economy s fundamentals information on aggregate productivity is dispersed across agents and there are two aggregate shocks a standard productivity shock and a noise shock affecting public beliefs about aggregate productivity neither the central bank nor individual agents can distinguish the two shocks when they are realized despite the lack of superior information monetary policy can affect the economy s relative response to the two shocks as time passes better information on past fundamentals becomes available the central bank can then adopt a backward looking policy rule based on more precise information about past shocks by announcing its response to future information the central bank can influence the expected real interest rate faced by forward looking consumers with different beliefs and thus affect the equilibrium allocation if the announced future response is sufficiently aggressive the central bank can completely eliminate the effect of noise shocks however this policy is typically suboptimal as it leads to an excessively compressed distribution of relative prices the optimal monetary policy balances the benefits of aggregate stabilization with the costs in terms of cross sectional efficiency copyright wiley blackwell
