the phillips curve macroeconomic policy and the welfare of canadians a review of the two competing paradigms explaining inflation and unemployment fluctuations singles out the keynesian phillips curve as the clear empirical winner over its classic competitors reestimation of the canadian phillips curve for 1957 90 identifies a sharp structural shift toward a high degree of unemployment hysteresis after 1972 the recent attempt of macropolicy to flatten the aggregate demand curve and limit supply side shock accommodation which aims at lower and more stable inflation is then shown to make unemployment higher and more unstable on average to an extent that is an increasing function of the degree of hysteresis understanding and reducing hysteresis and developing a consensus based incomes policy that has a chance of alleviating the dismal trade off should therefore to top research and policy priorities

bubbles and experience an experiment we investigate the occurrence of bubble crash pricing patterns in laboratory financial markets with a mixture of experienced and inexperienced traders we find that even with a minority of experienced traders bubbles are substantially abated

the second best core an economy with a single output and input is considered for the case of economies of scale in production equilibria are studied for a cooperative game of joint production in which goods are allocated by a price system the paper proposes a second best core in which allocations that are feasible for a coalition must be attainable by a price system existence is examined and properties of second best core allocations are analyzed copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

models of inflation expectations formation a comparison of household and economist forecasts the recent appreciation of the critical role played by expectations of inflation in the behavior of macromodels has stimulated empirical studies of the formation of expectations by different groups time series survey data on expectations of inflation exist now for economists households and businesses these data have been used as independent variables in explaining wage behavior gordon 16 turnovsky and wachter 34 and de menil and bhatta 5 prices turnovsky and wachter 34 and wachtel 36 interest rates gibson 14 hendershott and van horne 19 pearce 30 and mishkin 27 and consumption wachtel 36 generally with a significant improvement in explanatory power they have also been used as dependent variables in attempts to determine how expectations are formed by gordon 15 mullineaux 28 jacobs and jones 20 and figlewski and wachtel 9 for the economist survey van duyne 35 for the household survey and leonard 23 and de leeuw and mckelvey 4 for businesses given their different levels of knowlege of economics and perspectives one might expect that the models used by the different groups to forecast inflation would

analysts interim earnings forecasts evidence on the forecasting process existing empirical evidence indicates that analyst forecasts of corporate earnings do not meet the strict rationality standards prescribed by econometric tests of the rational expectations hypothesis 1 in this paper we address the question of whether the expectation formation process underlying analyst forecasts is adaptive or whether these forecasts are influenced by noninformational factors such as incentives arising from the market for their forecasts o brien 1988 lin and mcnichols 1993 francis and philbrick 1993 and dugar and nathan 1992 and interaction between judgmental and or statistical forecasting methods bunn and wright 1991 fan 1990 and hoerl and kennard 1970 the rejection of rational expectations gives rise to two views of the forecasting process of analysts the first based on an informational argument is that the forecasting process is adaptive marcet and sargent

macroeconomic forecasts and microeconomic forecasters in the presence of principal agent problems published macroeconomic forecasts by professional economists may not measure expectations forecasters may use their forecasts in order to manipulate beliefs about their ability i test a cross sectional implication of models of reputation and information revelation i find that as forecasters become older and more established they produce more radical forecasts since these more radical forecasts are in general less accurate ex post forecast accuracy grows significantly worse as forecasters become older and more established these findings are consistent with reputational factors at work in professional macroeconomic forecasts

game theoretic modeling of increasing returns to scale abstract this paper surveys the analysis by means of cooperative game theory of economies in which there are increasing returns to scale in the first section necessary and sufficient conditions for the existence of a core of a general equilibrium economy are considered in the second section the partial equilibrium approach to increasing returns production which developed along with the natural monopoly literature is surveyed the close relationship between the general equilibrium and partial equilibrium approaches is emphasized

bubbles crashes and endogenous expectations in experimental spot asset markets1 spot asset trading is studied in an environment in which all investors receive the same dividend from a known probability distribution at the end of each of t 15 or 30 trading periods fourteen of twenty two experiments exhibit price bubbles followed by crashes relative to intrinsic dividend value when traders are experienced this reduces but does not eliminate the probability of a bubble the regression of changes in mean price on lagged excess bids number of bids minus the number of offers in the previous period p pt a f b 1 o l supports the hypothesis that a e d the one period expected value of the dividend and that f 0 where excess bids is a surrogate measure of excess demand arising from homegrown capital gains losses expectations thus when bt 1 o goes to zero we have convergence to rational expectations in the sense of fama 1970 that arbitrage becomes unprofitable the observed bubble phenomenon can also be interpreted as a form of temporary myopia tirole 1982 from which agents learn that capital gains expectations are only temporarily sustainable ultimately inducing common expectations or priors tirole 1982 four of twenty six experiments all using experienced subjects yield outcomes that appear to the chart s eye to converge early to rational expectations although even in these cases we get 0 and small price fluctuations of a few cents that invite scalping

inflation expectations in turkey learning to be rational turkey implemented an ambitious restructuring of the economy in the past several years including the adoption of inflation targeting along with a floating exchange rate regime inflation came down from almost triple digits to single digits between 2001 and 2005 this particular episode of the turkish economy sets a genuine case study for investigating the possible changes in the behaviour of inflation expectations upon a regime shift accordingly this study analyses inflation expectations in turkey focusing especially on the post 2001 transition phase we first conduct classical tests of unbiasedness and efficiency using aggregate survey data between august 2001 and october 2007 to get a statistical benchmark for rationality we find that classical tests reject full rationality hypothesis for all series except next month s consumer price index cpi inflation expectations then we carry out time varying parameter tvp estimates based on a kalman filter to see how the coefficients in the classical tes

inflation forecast errors and time variation in term premia the expectations theory of the term strueture is well known to give wrong signals as to the future course of long term interest rates one explanation involves rational time varying term premia however the anomaly may also be due to inflation forecast errors we study survey forecasts of inflation it seems that the respondents forecasts are insufficiently adaptive interest rates reflect expectations similar to the inflation forecasts as a result past survey forecast errors reliably predict premia on u s government bonds

bettor handicapping and market efficiency in greyhound parimutuel gambling this paper evaluates the speculative efficiency of the parimutuel gambling market for greyhound racing the efficiency tests consider the informational content of bettor handicapping data as well as the forecasts of professional handicappers and the aggregate market previous studies have failed to consider the wide range of performance data that are available for bettor handicapping activities two tests of efficiency are considered the first test evaluates the in sample explanatory power of the handicapper s forecasts and handicapping data relative to the aggregate market s forecasts as indicated by the final odds the second test compares simulated rates of return to hypothetical gambling obtained from ex ante finish forecasts to the efficient rates of return that are dictated by the track s commission significant speculative inefficiencies are revealed the second test suggests the existence of above normal returns to gambling from using conditional forecasts generated from bettor handicapping data

wage expectations in the labor market survey evidence on rationality using a new set of directly observed wage expectations among firms this paper finds that in general firms forecasts fail the unbiasedness and efficiency requirements of weak form rational expectations these market participants consistently underestimate the wages they actually end up paying and their expectations do not efficiently utilize the information in past realizations the mean absolute forecast error of two percent compares with an error of only five percent if static expectations were held the major source of wage fore cast error seems to be errors in predicting demand rather than in predicting supply or the general price level wage forecast errors are positively correlated across fields with distinct supply patterns and are positively correlated with quantity forecast error the properties of stochastically weighted expectations and the effectiveness of the wage and price controls of the early 1970 s are also discussed this abstract was borrowed from another version of this item

introduction to the stability of rational expectations equilibrium abstract this paper surveys the literature which examines the stability of the expectations that agents are assumed to have in a rational expectations equilibrium ree this issue is more complex than the usual statistical estimation problem because the relationship between observable variables and payoff relevant variables is endogenous one approach taken in the literature yields convergence to a ree but requires agents to have extensive knowledge about the structure and dynamics of the model that prevails while they learn a second approach does not assume that agents have correctly specified likelihood functions and finds that ree may not be stable

nominal interest rates as indicators of inflation expectations forward interest rates have become popular indicators of inflation expectations theusefulness of this indicator depends on the relative volatilty and the correlation of inflation expectations and expected real interest rates this paper studies u s and u k data using a range of different tools and data sets the forward rate rule perfoms reasonably well in spite of significant movements in the expected real interest rate the reason is that the noise that movements in the expected real interest rate add to the inflation expectations is balanced by a tendency for expected real interest rates and inflation expectations to move in opposite directions

a core selection for regulating a single output monopoly we consider a single output production economy in which all coalitions of agents have access to the technology under increasing returns to scale the corresponding cooperative game without side payments is convex and hence has a large core we propose a core selection that is obtained by considering the lowest price of output relative to input such that the corresponding vector of indirect utilities is feasible the constant returns equivalent allocation is feasible and achieves this utility vector it satisfied the property of technological monotonicity when the production possibility set expands no agent faces a utility loss technological monotonicity and the core property together characterize the constant returns equivalent solution

bias in federal reserve inflation forecasts is the federal reserve irrational or just cautious abstract inflation forecasts of the federal reserve seem to have systematically under predicted inflation from the fourth quarter of 1968 until volcker s appointment as chairman and to systematically over predict it afterwards until the second quarter of 1998 furthermore under quadratic loss commercial forecasts seem to have information not contained in those forecasts to investigate the cause of this apparent irrationality this paper recovers the loss function implied by federal reserve s inflation forecasts the results suggest that the cost of having inflation above an implicit time varying target was larger than the cost of having inflation below it for the period since volcker and that the opposite was true for the pre volcker era once these asymmetries are taken into account the federal reserve s inflation forecasts are found to be rational

using survey data to test standard propositions regarding exchange rate expectations survey data provide a measure of exchange rate expectations superior to the forward rate in that no risk premium interferes we estimate extrapolative adaptive and regressive models of expectations static or random walk expectations and bandwagon expectations are rejected current appreciation generates the expectation of future depreciation because variables other than the contemporaneous spot rate receive weight in comparing expectations to the process governing the spot rate we find statistically significant bias no variable is as ubiquitous in international financial theory and yet as elusive empirically as investors expectations regarding exchange rates in the past expectations have been modeled in an ad hoc way often by using the forward exchange rate there is however a serious problem with using the forward discount as the measure of the expected change in the exchange rate in that the two may not be equal the gap that may separate the forward discount and expected depreciation is generally interpreted as a risk premium most of the large empirical literature testing the unbiasedness of the forward exchange rate for example has found it necessary either arbitrarily to assume away the existence of the risk premium if the aim

do journals accept too many papers abstract this paper provides a theoretical model for analyzing the behavior of peer reviewed journals it finds that apart from natural human errors inefficiencies arise purely for reasons of inter journal strategic behavior specifically as a result of competition journals tend to set their quality cut offs excessively low

the formation of price forecasts in experimental markets this study utilizes laboratory experimental methods to evaluate the empirical validity of 1 muthian rational expectations assumptions 2 an adaptive expectations model and 3 an extrapolative expectations model over 5 00 price forecasts from 146 participants in twelve experimental double auction m arkets with a cash reward structure are analyzed the forecasting objective is t hemean price over a sequence of trading periods governed by stationary market parameters the price forecasts are found to be inconsistent with strict muthian rational expectations and the extrapolative modelis not supported by the data however the forecasts generally support the adaptive expectations model copyright 1987 by ohio state university press

pattern recognition and procedurally rational expectations abstract this paper introduces a model of pattern recognition for assessing probabilities of future events experimental data from a time series setting indicates that the proposed model gives a better account of subjects expectation formation than the hypothesis of rational expectations parameter estimates suggest that individuals typically modify their behavior only with respect to some patterns while keeping other pattern responses unchanged in the light of new data when the individual data are used to simulate an asset market several features of speculative markets emerge large deviations of the market price from the fundamental price price movements in times without innovation in the fundamentals and large and variable levels of trading activities these regularities are shown to be consistent with pattern induced changes in expectations

an analysis of a panel of spanish gdp forecasts this article undertakes an analysis of the forecasts included in the panel of spanish forecasts in order to highlight the fact that the predictions made and the errors committed by the entities participating on this panel contain information that is particularly useful in analysing the evolution of the spanish economy here a study is undertaken of the gdp growth forecasts for the spanish economy for the period 2000 to 2002 made in distinct forecast time horizons specifically it analyses whether the forecasts are optimistic or pessimistic and whether new information concerning the variable being predicted is used efficiently in revising earlier forecasts

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

do professional forecasters trust in taylor type rules evidence from the wall street journal poll this article uses the monthly wall street journal poll between 2002 and 2010 to analyse whether professional economic forecasters believe in and thus apply taylor type rules for their own forecasts using their forecasts for the federal funds rate the inflation rate and capacity utilization we estimate whether these are internally consistent with the message of taylor type rules we find that the expectation formation can indeed be described by taylor type rules

efficiency and formation of expectations evidence from the european investment survey the european commission conducts an annual survey regarding planned and realized business fixed investment across various manufacturing sectors in euroland in this study we investigate the predictive content of survey based expectations on investment in addition we empirically test the rationality of respondents both in a time series as well as in a panel context according to our results based on pooling the data efficiency is rejected since expectations are biased predictors of actual outcomes furthermore expectations revisions are found to be correlated with components of the information set known at the time of decision making finally our results qualify regressive expectations as the mechanism that more adequately describes the formation of expectations

the informational efficiency of experimental asset markets a fundamental difficulty in devising any test of general efficient market hypotheses is the specification of the relevant public and private information sets of traders without a consensus as to reasonable empirical specifications tests of the hypotheses remain minimal or controversial in this study we examine the efficiency of experimental asset markets in which one may unambiguously identify the public and private information sets of traders we focus on how market efficiency is affected by the presence of futures markets in settings that incorporate different types of uncertainty and inside information our experimental results support four conclusions 1 market outcomes tend to evolve toward strong form informationally efficient equilibria whether or not futures markets and or event uncertainty are present 2 the presence of futures markets clearly stabilizes spot prices 3 the presence of futures markets tends to speed the evolution of asset markets to more efficient equilibria where there

vested interest and biased price estimates evidence from an auction market this study employs a new data set from art auctions to examine the relationship between auctioneer presale price estimates and the long term performance of artworks we find that the price estimates for expensive paintings have a consistent upward bias over a long period of 30 years high estimates at the time of purchase are associated with adverse subsequent abnormal returns moreover the estimation error for individual paintings tends to persist over time these results are consistent with the view that auction house price estimates are affected by agency problems and that

the slowdown of the economics publishing process over the last three decades there has been a dramatic slowdown of the publication process at top economics journals a substantial part is due to journals requiring more extensive revisions various explanations are considered democratization of the review process increases in the complexity of papers growth of the profession and cost and benefit arguments changes in the profession are examined using time series data connections between these changes and the slowdown are examined using paper level data there is evidence for some explanations but most of the slowdown remains unexplained changes may reflect evolving social norms

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

efficiency of experimental security markets with insider information an application of rational expectations models the study reports on the ability of competing models of market information integration and dissemination to explain the behavior of simple laboratory markets for a one priced security returns to the security depended upon a randomly drawn state of nature some agents insiders whose identity was unknown to other agents knew the state before the markets opened with replication of market conditions the predictions of a fully revealing rational expectations model are relatively accurate prices adjusted immediately to near rational expectations prices profits of insiders were virtually indistinguishable from non insiders and efficiency levels converged to near 100 percent

the replacement principle in economies with single peaked preferences abstract our objective is to investigate the implications of the replacement principle for the fair allocation of an infinitely divisible commodity among agents with single peaked preferences the principle says that when one of the components of the data entering the description of the problem to be solved changes all of the relevant agents should be affected in the same direction they all gain or they all lose we apply it to situations in which the preferences of one of the agents may change under the name ofwelfare domination under preference replacement we show that there is no selection from the no envy and pareto solution satisfying it then we weaken it by limiting its application to situations in which the change is not so disruptive that it turns the economy from one in which there is too little of the commodity to one in which there is too much or conversely we show that there is only one selection from the no envy and pareto solution satisfying this property andreplication invariance it is the uniform rule a solution that has played a central role in previous analyses of the problem journal of economic literatureclassification numbers d51 d63 d70

imperfect information and wage inertia in the business cycle a comment in a recent article gertler 1982 presents a model that explains certain stylized facts concerning the relative behavior of the money supply and nominal wages one additional feature of the model is the behavior of real output which is found to have a serially correlated response to a money supply shock this serial correlation appears to arise from an information structure that precludes agents from directly disentangling permanent versus transitory movements in relevant state variables this information structure complicates the forecasting problem that must be solved to analyze the model and affects the behavior of wages and the variance of output it will not however lead to serial correlation in real output an algebraic error is responsible for the serial correlation found by gertler this note corrects the error and presents an alternative solution to the forecasting problem gertler constructs forecasts of the relevant state variable through the use of a kalman filter while this technique is appropriate for the problem a simpler solution is available this solution is based on an equivalent representation of the stochastic process generating the disturbances of the model this equivalent representation can then be used in a straightforward way to describe wage dynamics and the variance of real output it is sufficient to analyze gertler s model in the case where there are only monetary disturbances the relevant equations are

are statistical reporting agencies getting it right data rationality and business cycle asymmetry this article provides new evidence on the rationality of early releases of industrial production ip and producer price index ppi data rather than following the usual practice of examining only first available and fully revised data we examine the entire revision history for each variable thus we are able to assess for example whether earlier releases of data are in any sense less rational than later releases and when data become rational our findings suggest that seasonally unadjusted ip and ppi become rational after approximately 3 4 months whereas seasonally adjusted versions of these series remain irrational for at least 6 12 months after initial release for all variables examined we find evidence that the remaining revision is predictable from its own past or from publicly available information in other economic and financial variables in addition we find a clear increase in the volatility of revisions during recessions suggesting that early data releases are less reliable in toughe

forecast uncertainty ex ante and ex post u s inflation and output growth survey respondents who make point predictions and histogram forecasts of macro variables reveal both how uncertain they believe the future to be ex ante as well as their ex post performance macroeconomic forecasters tend to be overconfident at horizons of a year or more but overestimate i e are underconfident regarding the uncertainty surrounding their predictions at short horizons ex ante uncertainty remains at a high level compared to the ex post measure as the forecast horizon shortens there is little evidence of a link between individuals ex post forecast accuracy and their ex ante subjective assessments

forecasting dynamics and convergence to market fundamentals evidence from experimental asset markets abstract subjects trade shares of a fictitious asset in a computerized double auction market and submit one period ahead forecasts of the mean contract price on average the predictions of the rational expectations hypothesis are not supported and forecasts tend to be both biased and inconsistent with the specification of the process which would generate prices in a rational expectations equilibrium nevertheless an empirical analysis of agents forecasting dynamics indicates that learning does occur and that agents forecasts evolve in a direction consistent with a rational expectations equilibrium

momentum and overreaction in experimental asset markets abstract price volatility and investor overreactions are commonplace in experimental asset markets understanding the price dynamics in these markets is crucial for designing successful new trading institutions we report on a series of experiments to test the predictions of a new momentum model using a dynamical systems approach this model is then pitted against several standard models to predict prices as well as against expert human forecasters the comparative results suggest that each model has its advantages and regions of best performance overall the best predictive methods are the momentum model and expert human forecasters

egalitarian equivalent cost sharing of a public good in an economy with one public and one private good egalitarian equivalent cost sharing consists of finding the highest public good level x such that consuming x for free yields a feasible utility distribution the corresponding feasible allocation typically unique called egalitarian equivalent is in the core of the economy conversely any cost sharing method satisfying pareto optimality cost monotonicity nobody suffers a utility loss if the production technology improves upon ceteris paribus and individual rationality no single agent coalition objects or no private transfers no agent receives a positive amount of private good must select an egalitarian equivalent allocation in every economy copyright 1987 by the econometric society

on the rationality of us macroeconomic forecasts evidence from a panel of professional forecasters asa nber survey data is used to check the rationality of us macroeconomic forecasts it is found that of 75 forecast series examined 51 are biased 25 are both unbiased and efficient and only two pass the null hypothesis of orthogonality this calls into question the validity of rational expectations hypothesis

on publication refereeing and working hard we present a model for academia with heterogeneous author types and endogenous effort to evaluate recent changes in the publication process in economics we analyze the implications of these developments on research output lowering the precision of refereeing signals lowers the effort choices of intermediate ability authors but invites more submissions from less able authors increasing the number of journals stimulates less able authors to submit their papers the editor can improve the journal s quality pool of submitted manuscripts by improving the precision of refereeing but not by lowering acceptance standards the submission strategy of an author is informative of his ability

firm performance and macro forecast accuracy abstract combining a unique survey of japanese firms gdp forecasts with accounting data for 25 years we find three main results first firms gdp forecasts are associated with their employment investment and output growth in the subsequent year second over optimistic and pessimistic forecast errors predict lower profitability and productivity consistent with our model of input choice under uncertainty third larger and more cyclical firms make forecasts closer to professionals presumably reflecting their higher return to accuracy forecasts by more productive and older firms are also more similar to professional forecasts implying forecasting ability is linked to management ability and experience

thar she blows can bubbles be rekindled with experienced subjects we report 28 new experiment sessions consisting of up to three experience levels to examine the robustness of learning and error elimination among participants in a laboratory asset market and its effect on price bubbles our answer to the title question is yes we impose a large increase in liquidity and dividend uncertainty to shock the environment of experienced subjects who have converged to equilibrium and this treatment rekindles a bubble however in replications of that same challenging environment across three experience levels we discover that the environment yields a rare residual tendency to bubble even in the third experience session therefore a caveat must be placed on the effect of twice experienced subjects in asset markets in order for price bubbles to be extinguished the environment in which the participants engage in exchange must be stationary and bounded by a range of parameters experience including possible error elimination is not robust to major new environment changes in determining the characteristics of a price bubble jel c91 d83

tests of equilibrium macroeconomics using contemporaneous monetary data abstract this paper uses contemporaneous monetary data to carry out econometric tests of the equilibrium approach to modelling the relation between monetary disturbances and macroeconomic fluctuations the theoretical analysis introduces into an equilibrium macroeconomic model the availability of preliminary data on current monetary aggregates and the process of accumulation of revised monetary data the econometric analysis tests two hypothesis derived from this extended model one hypothesis concerns the neutrality of perceived monetary policy the econometric results imply rejection of this hypothesis the other hypothesis concerns the non neutrality of errors in preliminary monetary data the econometric results fail to reject the contrary of this hypothesis these tests provide strong evidence against the reality of the equilibrium approach

forecasters as imperfect information processors experimental and survey evidence abstract one step ahead forecasts of random walks with four different variances are collected from student subjects the increasing variance creates a more complex learning environment and engenders forecasts that deviate from the rational expectation a 1 increase in the standard deviation of information released after the forecast date creates a 0 9 increase in the standard deviation of forecasts from rational expectations the effect is remarkably strong and is even stronger in survey data collected from professional forecasters one potential application is the stock market as random shocks undermine consensus and induce volatility which undermines consensus we also find that deviations from rational expectations are serially correlated

the structure of expectations of the weekly money supply announcement abstract this paper examines the structure of expectations of the weekly money supply announcement in the late 1970s the data used are from a weekly telephone survey of money market participants the rationality and structure of expectations are explored with the data organized in three ways the mean response to each weekly survey the pooled sample of individual responses and time series of responses by each individual in the survey the effect of data aggregation on rationality tests is investigated the structure of the expectations data are also examined and it is found that both strong regressive influences and adaptive learning characterize the data

asymmetry complementarities and state dependence in federal reserve forecasts forecasts are a central component of policymaking the federal reserve s forecasts are published in a document called the greenbook previous studies of the greenbook s inflation forecasts have found them to be rationalizable but asymmetric if considering particular subperiods for example before and after the volcker appointment in these papers forecasts are analyzed in isolation assuming policymakers value them independently we analyze the greenbook forecasts in a framework in which the forecast errors for different variables are allowed to interact we find that allowing the losses to interact makes the unemployment forecasts virtually symmetric the output forecasts symmetric prior to the volcker appointment and the inflation forecasts symmetric after the onset of the great moderation

is bank supervision central to central banking whether central banks should play an active role in bank supervision and regulation is being debated both in the united states and abroad while the bank of england has recently been stripped of its supervisory responsibilities and several proposals in the united states have advocated removing bank supervision from the federal reserve system other countries are considering enhancing central bank involvement in this area many of the arguments for and against these proposals hinge on the effect this change would have on the ability of the central bank to conduct monetary policy we find that confidential supervisory information on bank ratings significantly improves

welfare bounds in the cooperative production problem a general model of lower bound individual rationality and upper bound axioms for fair allocation is proposed the unanimity welfare function associates to each individual utility function the highest equal utility feasibile when all agents share this utility if this function is a feasible lower bound resp upper bound then it is the highest lower bound of all resp the lower upper bound applying this to cooperative production of private goods we characterize when the unanimity welfare is a lower upper bound function and when the stand alone welfare is an upper or lower bound our approach unifies several familiar fairness properties

the rationality of usda forecasts under multivariate asymmetric loss a large number of previous studies suggest that many usda forecasts are biased and or inefficient these findings however may be the result of the assumed loss function of usda forecasters we test the rationality of the usda net cash income forecasts and the wasde production and price forecasts between 1988 and 2018 using a flexible multivariate loss function that allows for asymmetric loss and non separable forecast errors our results provide robust evidence that usda forecasters are rational expected loss minimizers yet demonstrate a tendency to place a greater weight on under or overprediction as a result this study provides an alternate interpretation of previous findings of forecast irrationality

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

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

frequency bias in consumers perceptions of inflation an experimental study we investigate whether the perception of economy wide inflation is affected by the frequency with which various goods prices are observed we provide novel experimental evidence that consumers perceptions of aggregate inflation are systematically biased toward the perceived inflation rates of the frequently purchased items this frequency bias may affect consumers consumption and investment decisions and thus have important macroeconomic consequences it may also explain why consumers typically over estimate inflation in surveys during periods where frequently purchased non durable goods are inflating faster than durables
