how useful are the forecasts of intergovernmental agencies the imf and oecd versus the consensus this study compares the accuracy and information content of economic forecasts for g7 countries made in the 1990s by the oecd and imf the benchmarks for comparison are the average forecasts of private sector economists published by consensus economics with few exceptions the private sector forecasts are less biased and more accurate in terms of mean absolute error and root mean square error formal tests show these differences are statistically significant for forecasts of real growth and production less so for forecasts of inflation and unemployment overall there appears little information in the oecd and imf forecasts that could be used to reduce significantly the error in the private sector forecasts

an economic theory of self control the concept of self control is incorporated in a theory of individual intertemporal choice by modeling the individual as an organization the individual at a point in time is assumed to be both a farsighted planner and a myopic doer the resulting conflict is seen to be fundamentally similar to the agency conflict between the owners and managers of a firm both individuals and firms use the same techniques to mitigate the problems which the conflicts create this paper stresses the implications of this agency model and discusses as applications the effect of pensions on saving saving and the timing of income flows and individual discount rates

failures in contingent reasoning the role of uncertainty we propose a new channel to account for the difficulties of individuals with contingent reasoning the presence of uncertainty when moving from an environment with one state of known value to one with multiple possible values two changes occur first the number of values to consider increases second the value of the state is uncertain we show in an experiment that this lack of certainty or the loss of the power of certainty impedes payoff maximization and that it accounts for a substantial portion of the difficulties with contingent reasoning

price setting during low and high inflation evidence from mexico this paper provides new insight into the relationship between inflation and the setting of individual prices by examining a large data set of mexican consumer prices covering episodes of both low and high inflation when the annual rate of inflation is low below 10 15 the frequency of price changes comoves weakly with inflation because movements in the frequency of price decreases and increases partly offset each other in contrast the average magnitude of price changes correlates strongly with inflation because it is sensitive to movements in the relative shares of price increases and decreases when inflation rises beyond 10 15 few price decreases are observed and both the frequency and average magnitude are important determinants of inflation i show that a menu cost model with idiosyncratic technology shocks predicts the average frequency and magnitude of price changes well over a range of inflation similar to that experienced by mexico

rational heuristics expectations and behaviors in evolving economies with heterogeneous interacting agents we analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent based model populated by heterogeneous interacting firms agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change imperfect information coordination hurdles and structural breaks in these circumstances we find that neither individual nor macroeconomic dynamics improve when agents replace myopic expectations with less naive learning rules our results suggest that fast and frugal robust heuristics may not be a second best option but rather rational responses in complex and changing macroeconomic environments jel c63 d8 e32 e6 o4

information rigidities inflation perceptions and the media lessons from the euro cash changeover the objective of theoretical models of information rigidities is to capture the fact that people are constrained in their ability to acquire and process all available information given that most people obtain their information about the economy from the media press coverage of the economy may exert an influence on peoples attitudes this paper tests for this influence by examining consumers inflation perceptions in the aftermath of the euro cash changeover which serves as a natural experiment using a new data set that quantifies the intensity and tone of media reports we document that media reporting has had a statistically significant and economically meaningful impact on inflation perceptions and contributed to their sharp rise in the aftermath of the euro cash changeover and to the divergence between inflation perceptions and actual inflation rates jel e53 d83

does my contribution to your crowdfunding project matter abstract in this study we consider the dynamics of crowdfunding project support over time we propose that people support crowdfunding projects financially when they believe that their contribution will make an impact because perceptions of impact are positively related to goal proximity we predict that support for a crowdfunding project will increase as the project funding approaches its target goal in addition because motivation decreases after a goal is attained we further predict that crowdfunding contributions will significantly decrease after the target goal is reached we find strong support for these hypotheses from a large scale field study involving kickstarter furthermore we show that several factors related to the expected impact moderate the effects of goal proximity that is the positive effect of goal proximity on project support is accentuated if the project is nearing its funding deadline if the target goal is relatively small or if the project has limited early support

the economics of small business finance the roles of private equity and debt markets in the financial growth cycle abstract this article examines the economics of financing small business in private equity and debt markets firms are viewed through a financial growth cycle paradigm in which different capital structures are optimal at different points in the cycle we show the sources of small business finance and how capital structure varies with firm size and age the interconnectedness of small firm finance is discussed along with the impact of the macroeconomic environment we also analyze a number of research and policy issues review the literature and suggest topics for future research

growth forecasts belief manipulation and capital markets abstract we analyze how a benevolent privately informed government agency would optimally release information about the economy s growth rate when the agents hold heterogeneous beliefs we model two types of agent conforming and dissenting the former has a prior that is identical to that of the government agency whereas the latter has a prior that differs from that of the government agency we identify both informative and uninformative equilibria informative equilibria are equilibria in which the government agency s equilibrium signal leads to a revision of beliefs we demonstrate that the uninformative equilibria can in fact dominate the informative ones in terms of ex post social welfare

monetary shocks in models with inattentive producers we study models where prices respond slowly to shocks because firms are rationally inattentive producers must pay a cost to observe the determinants of the current profit maximizing price and hence observe them infrequently to generate large real effects of monetary shocks in such a model the time between observations must be long and or highly volatile previous work on rational inattentiveness has allowed for observation intervals that are either constant but long e g caballero 1989 or reis 2006 or volatile but short e g reis s 2006 example where observation costs are negligible but not both in these models the real effects of monetary policy are small for realistic values of the duration between observations we show that non negligible observation costs produce both of these effects intervals between observations are infrequent and volatile this generates large real effects of monetary policy for realistic values of the average time between observations

asymmetric information and rational expectations when is it right to be wrong abstract in this paper we examine the effects of private agents being less than fully rational in their expectations we examine this in the context of monetary policy where the central bank may have uncertain preferences either by choice or by necessity the new feature is that we allow the public to react in two different ways they either form rational expectations and internalize the uncertainty about the central bank s preferences in full or alternatively and if this process of internalization is costly it forms a best guess regarding those preferences this implies a certainty equivalence strategy applied to the preference parameters as those parameters enter the decisions non linearly a systematic error emerges we examine the magnitude of the resulting error in inflation and output following the assumption of certainty equivalence under all reasonable levels of uncertainty this error turns out to be small but involves trading a deflation bias against the cost of gathering the information needed for the full information rational expectations solution

differential interpretation in the survey of professional forecasters in this paper i estimate a simple bayesian learning model to expectations data from the survey of professional forecasters i reformulate the model in terms of forecast revisions which allows one to abstract from differences in priors and to focus the analysis on the relationship between news and revisions the empirical analysis shows that there is significant heterogeneity in the interpretation of news among forecasters in particular at longer horizons while it decreases closer to the forecast target date the results also indicate a positive relationship between prior sentiment and interpretation of the signal in the sense that relatively optimistic pessimistic forecasters are likely to believe that the signal under over estimates the future realization and assign it a low high weight in the forecast revision

rationally inattentive seller sales and discrete pricing prices tend to remain constant for a period of time and then jump in the literature this rigidity is usually interpreted to reflect a cost of adjusting prices this article shows that price rigidity can alternatively reflect optimal price setting when there are no adjustment costs namely if the seller is rationally inattentive the model generates non trivial pricing patterns that are consistent with the data and that are hard to explain with the traditional adjustment cost model in particular prices are adjusted frequently but move back and forth between a few given values hazard functions are downward sloping and responses to persistent shocks are sluggish these results are obtained in a model that implements rational inattention without simplifying assumptions on the functional forms of the processed signals

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

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

vintage production models of u k manufacturing industry vintage production models for the u k are extended to cover hours worked as a separate element of labour input the main purpose of the analysis is then to ascertain whether the output of manufacturing as measured by some index can be satisfactorily explained as a simple stable function of a small number of input aggregates

outside enterpreneurial capital this article investigates factors that affect rejection rates in applications for outside finance among different types of investors banks venture capital funds leasing firms factoring firms trade customers and suppliers partners and working shareholders private individuals and other sources taking into account the non randomness in a firm s decision to seek outside finance the data support the traditional pecking order theory further the data indicate that firms seeking capital are typically able to secure their requisite financing from at least one of the different available sources however external finance is often not available in the form that a firm would like this article engages with four interrelated empirical questions first what are the characteristics of privately held entrepreneurial firms that seek external outside finance and what drives the request for capital from the different potential sources of external finance banks venture capitalists private individuals leasing factoring suppliers customers partners working shareholders among other sources second what are the factors that lead to rejection or acceptance of requests for external finance given this non randomness in the types of firms that seek external finance in the spirit of heckman 1976 1979 third as various forms of financing are far from being perfect substitutes are there differences in the ability of firms to obtain capital from the different available sources fourth can firms obtain all of their desired capital from the different available sources even if it is not in the form they would like it is widely recognised that the decision to seek external finance and the type of financing sought is related to information asymmetries faced by investors regarding the entrepreneurial firm s quality see for example jensen and meckling 1976 1 where

optimal monetary policy and transparency under informational frictions this paper examines the optimal monetary policy and central bank transparency in an economy where firms set prices under informational frictions the economy is subject to two types of shocks determining the efficient output level and firms desired markups to minimize the welfare reducing output gap and price dispersion between firms the central bank controls firms incentives and expectations by using a monetary instrument and disclosing information on the realized shocks this paper shows that an optimal policy comprises the disclosure of a linear combination of the two shocks and the adjustment of monetary instruments contingent on the disclosed information

forecasting efficiency concepts and applications this article introduces the concept of forecast efficiency in which the forecast contains all information available at the time of the forecast empirical tests investigate weak efficiency where the information set is all past forecasts and where all forecast revisions and errors should be uncorrelated with past forecast revisions tests of macroeconomic energy consumption and oil price forecasts find a significant autocorrelation of forecast revisions with fifty of fifty one tests showing positive correlation of forecast revisions as opposed to zero correlation consistent with forecast efficiency copyright 1987 by mit press

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

what s in a picture evidence of discrimination from prosper com abstract we find evidence of significant racial disparities in a new type of credit market known as peer to peer lending loan listings with blacks in the attached picture are 25 to 35 percent less likely to receive funding than those of whites with similar credit profiles despite the higher average interest rates charged to blacks lenders making such loans earn a lower net return compared to loans made to whites with similar credit profiles because blacks have higher relative default rates these results provide insight into whether the discrimination we find is taste based or statistical

predictability of output growth and inflation a multi horizon survey approach we develop an unobserved components approach to study surveys of forecasts containing multiple forecast horizons under the assumption that forecasters optimally update their beliefs about past current and future state variables as new information arrives we use our model to extract information on the degree of predictability of the state variable and the importance of measurement errors in the observables empirical estimates of the model are obtained using survey forecasts of annual gdp growth and inflation in the united states with forecast horizons ranging from 1 to 24 months and the model is found to closely match the joint realization of forecast errors at different horizons our empirical results suggest that professional forecasters face severe measurement error problems for gdp growth in real time while this is much less of a problem for inflation moreover inflation exhibits greater persistence and thus is predictable at longer horizons than gdp growth and the persistent component of bot

is the growth of small firms constrained by internal finance this paper examines the long standing theory that the growth of small firms is often constrained by the quantity of internal finance under plausible assumptions when financing constraints are binding an additional dollar of internal finance should generate slightly more than an additional dollar of growth in assets this quantitative prediction should not hold for the relatively small number of firms which access external equity we test these predictions with a panel of more than 1 600 small firms and find that the growth of most firms is constrained by internal finance our results have implications for several different research literatures including models of firm growth

rational inattention in uncertain business cycles the paper proposes endogenous information choice as a channel through which uncertainty affects price dynamics i consider a rational inattention model with volatility uncertainty and endogenous information processing capability according to the model firms learning and optimal attention exhibits inertia and asymmetry in response to volatility changes firms choose to process more information when uncertainty rises especially about aggregate conditions and their pricing behavior changes accordingly using a markov switching factor augmented vector autoregression ms favar the paper also documents a significant positive correlation between volatility and firms responsiveness to macro and microlevel shocks consistent with model predictions

elastic attention risk sharing and international comovements in this paper we examine the effects of elastic information processing capacity or elastic attention proposed in sims 2010 on international consumption and income correlations in a tractable small open economy soe model with exogenous income processes we find that in the presence of capital mobility in financial markets elastic attention due to a fixed information processing cost lowers the international consumption correlations by generating heterogeneous consumption adjustments to income shocks across countries facing different macroeconomic uncertainty in addition we show that elastic attention can improve the model s predictions for the other key moments of the joint dynamics of consumption and income

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

international evidence on the efficacy of new keynesian models of inflation persistence in this paper we take an agnostic view of the phillips curve debate and carry out an empirical investigation of the relative and absolute efficacy of calvo sticky price sp sticky information si and sticky price with indexation models spi with emphasis on their ability to mimic inflationary dynamics in particular we look at evidence for a group of 13 oecd countries and we consider three alternative measures of inflationary pressure including the output gap labor share and unemployment we find that the calvo sp and the si models essentially perform no better than a strawman constant inflation model when used to explain inflation persistence indeed virtually all inflationary dynamics end up being captured by the residuals of the estimated versions of these models we find that spi model is preferable because it captures the type of strong inflationary persistence that has in the past characterized the economies of the countries in our sample however two caveats to this conclusion are that improvement in performance is driven mostly by the time series part of the model i e lagged inflation and that the spi model overemphasizes inflationary persistence thus there appears to be room for improvement via either modified versions of the above models or via development of new models that better track inflation persistence

capacity growth in a clay clay vintage model in this paper the growth rates of capacity output and capacity demand for labour are derived for a clay clay vintage model the results are simple and directly applicable in the sense that they only depend on parameters and measurable variables

the effect of entrepreneurial rhetoric on microlending investment an examination of the warm glow effect microlending provides a valuable alternative to traditional financing for entrepreneurs in impoverished countries drawing from theory on political rhetoric and the concept of warm glow giving we examine characteristics of entrepreneurial narratives that are related to how quickly entrepreneurs receive funding using a sample of 6051 narratives from entrepreneurs in developing countries we demonstrate that narratives higher in language indicating blame and present concern lead to more rapid funding while narratives higher in accomplishment tenacity and variety lead to slower funding our findings suggest that the presentation of investment profiles should be carefully managed to maximize funding likelihood

precommitments for financial self control micro evidence from the 2003 korean credit crisis we analyze high frequency micro panel data on customers of a major korean credit card company before and after the 2003 korean credit crisis and find evidence of pervasive precommitment behavior that is difficult to explain using standard economic theories 1 customers voluntarily reduce their credit card borrowing limits without any compensation 2 customers turn down interest free installment loan offers with high probability and 3 of the small fraction of customers who do accept interest free loan offers most precommit to pay off the loan over a shorter term than the maximum allowed term under the offer

how well does sticky information explain the dynamics of inflation output and real wages abstract this paper finds that a model with sticky information is less successful than a standard model featuring nominal rigidities inflation indexation and habits in generating the dynamics triggered by technology shocks as estimated by a vector autoregression using u s macroeconomic data the real wage responses after a permanent increase in productivity clearly favor the standard model the sticky information model fails to replicate the observed inertial response in the real wage whereas the standard model relies on inflation indexation in wage setting to achieve a better fit the two models are however statistically equivalent after a shock in monetary policy

introduction funding gaps theoretical and empirical foundations of government policies to plug alleged business funding gaps are highly controversial but rarely subject to wide ranging in depth debate this symposium from major scholars in the field provides a counterbalance topics addressed cover the theory of lending under asymmetric information its implications for overlending relationship lending as a market solution to information asymmetries government emulation of private sector decision making to eliminate underprovision of high tech equity and theoretically based empirical work testing for funding deficiencies in the high tech sector despite the very different and potentially contradictory contributions the result is surprisingly a set of mutually agreed policy conclusions

frictions or mental gaps what s behind the information we don t use and when do we care consumers suffer significant losses from not acting on available information these losses stem from frictions such as search costs switching costs and rational inattention as well as what we call mental gaps resulting from wrong priors worldviews or relevant features of a problem not being top of mind most research studying such losses does not empirically distinguish between these mechanisms instead we show that most highly cited papers in this area presume one mechanism underlies consumer choices and assume away other potential explanations or collapse many mechanisms together we discuss the empirical difficulties that arise in distinguishing between different mechanisms and some promising approaches for making progress in doing so we also assess when it is more or less important for researchers to distinguish between these mechanisms approaches that seek to identify true value from demand without specifying mechanisms behind this wedge are most useful when researchers are interested in evaluating allocation policies that strongly steer consumers towards better options with regulation traditional policy instruments and defaults on the other hand understanding the precise mechanisms underlying consumer losses is essential to predicting the impact of mechanism policies aimed primarily at reducing specific frictions or mental gaps without otherwise steering consumers we make the case that papers engaging with these questions empirically should be clear about whether their analyses distinguish between mechanisms behind poorly informed choices and what that implies for the questions they can answer we present examples from several empirical contexts to highlight these distinctions

choosing between time and state dependence micro evidence on firms price reviewing strategies because of recent findings based on survey data it is now well known that firms differ from each other with respect to their price reviewing strategies while some firms review their prices at fixed intervals of time others prefer to perform price revisions in response to changes in economic conditions some theories have been suggested to explain this however empirical evidence on the relative importance of the factors that determine the different strategies of firms is virtually non existent in this paper we help to fill this gap by investigating the factors that explain why firms follow time dependent state dependent or both time and state dependent price reviewing rules we find that the strategies of firms vary with firm characteristics that have a bearing on the importance of information costs with the variability of the optimal price and with the sensitivity of profits to non optimal prices

the expected price of keeping up with the joneses abstract inflation expectations elicited in surveys have been found to exhibit large dispersion across individuals although several explanations have been proposed none fully explain this puzzle we explore in this paper a new behavioral factor social comparison using original survey data we find that respondents who feel they are falling behind compared to their peers report significantly and substantially higher inflation expectations we argue that this result is consistent with an experience based belief formation model in which those unable to keep up with the joneses overweight the high prices of aspiration goods they are unable to purchase

a quantized approach to rational inattention abstract in this paper i propose a model of rational inattention where the choice variable is a deterministic function of the exogenous variables and still only a finite amount of information is being used this holds provided the choice variable is discrete rather than continuous that is the mapping from the realization of the exogenous variables to the endogenous ones is piece wise constant thus limited information is now a source of lumpiness in behavior rather than a source of noise the approach is applied to a simple static model of price setting where individual price setters face aggregate monetary shocks and idiosyncratic productivity shocks the effect of aggregate money shocks on output and prices is studied it is shown that as the variance of idiosyncratic shocks become large the aggregate log price level converges to a linear function of the aggregate money shock with a coefficient which is strictly between 0 and 1 consequently unanticipated aggregate money shocks have real effects on output in contrast to the sticky price model of caplin and spulber 1987 but these effects are smaller than in standard rational inattention models or in the lucas 1972 misperception model

foundations for optimal inattention abstract this paper models an agent who has a limited capacity to pay attention to information and thus conditions her actions on a coarsening of the available information an optimally inattentive agent chooses both her coarsening and her actions by maximization of an underlying subjective expected utility preference relation net of a cognitive cost of attention the main result axiomatically characterizes the conditional choices of actions by an agent that are necessary and sufficient for her behavior to be seen as if it is the result of optimal inattention observing these choices permits unique identification of the agent s utility index the information to which she pays attention her attention cost and her prior whenever information is costly

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

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

monetary policy shocks expectations and information rigidities this paper contributes to the literature by assessing expectation effects from monetary policy for g7 economies we rely on expectation data from consensus economics and a panel vector autoregression framework which accounts for international spillovers and time variation we analyze whether monetary policy has changed the degree of information rigidity after the emergence of the subprime crisis and estimate effects of interest rate changes on expectations disagreements and forecast errors we find strong evidence for information rigidities and identify higher forecast errors by professionals after monetary policy shocks our results suggest that the international transmission of monetary policy shocks introduces noisy information and partly increases disagreement among forecasters jel e31 e52

actively learning by pricing a model of an experimenting seller this article presents a model of a rational seller who is actively learning the slope of his demand curve via his pricing strategy consequently this seller optimally experiments with his price resulting price patterns show a tendency for discreteness as observed in the data which has proved to be a major challenge to most price setting models the experimentation motive can also replicate the observation that prices are more volatile than costs as well as the presence of many idiosyncratic price changes in the data it can do so without a need to assume the existence of large idiosyncratic shocks

robustly strategic consumption portfolio rules with informational frictions this paper provides a tractable continuous time constant absolute risk aversion gaussian framework to explore how the interactions of fundamental uncertainty model uncertainty due to a preference for robustness and state uncertainty due to information processing constraints rational inattention affect strategic consumption portfolio rules and precautionary savings in the presence of uninsurable labor income specifically after solving the model explicitly i compute and compare the elasticities of strategic asset allocation and precautionary savings to risk aversion robustness and inattention furthermore for plausibly estimated and calibrated model parameters i quantitatively analyze how the interactions of model uncertainty and state uncertainty affect the optimal share invested in the risky asset and show that they can provide a potential explanation for the observed stockholding behavior of households with different education and income levels this paper was accepted by neng wang finance

the effects of professional forecast dissemination on macroeconomic volatility abstract this paper explores the role that professional forecast announcements can have on macroeconomic volatility bounded rational agents are used inside a medium scale dynamic stochastic general equilibrium dsge model with financial frictions modeled agents must form expectations about endogenous variables by selecting between three simple linear forecasting specifications some of which contain the inclusion of a professionally announced forecast of the economic variable historically calibrated simulations of the model show that the usage of the announced professional forecast by the agents in their adaptive learning forecast specifications can reduce the volatility in consumption inflation and wages by as much as 26 23 and 22 respectively however if the professional forecast is not disseminated well to the agents or biased in its dissemination agents will learn to ignore the announcement and macroeconomic volatility will increase further the inclusion of very noisy professional forecast signals can result in coordinated volatility cascades where agents could reduce macroeconomic volatility by ignoring the professional forecast but choose not to because of its previous forecast performance

rationality and the role of judgement in macroeconomic forecasting this paper examines the effects of judgemental adjustments on the rationality of macroeconomic forecasts published forecasts based on large scale models are rarely purely model based but often include extensive adjustments forecasters adjustments tend to improve forecast accuracy but there is no evidence of their impact on the rationality of forecasts using series of revisions to forecasts we find little evidence that published forecasts are excessively smooth in the nordhaus i 987 sense but intercept corrections do appear to reduce the variation over time in purely modelbased forecasts and to alter the underlying output inflation trade off implicit in the model there is a large literature on the rationality of forecasts and on the efficient use of information in forecasting equally it is now generally recognised that published forecasts are rarely based on the estimated model alone but that adjustments are often made to the model based predictions in arriving at a final forecast thus published forecasts reflect in varying degree the properties of the model and the skills of the model s proprietors while forecasters adjustments do appear to improve forecast accuracy see the work of the esrc

investment dynamics with information costs investment in physical capital at the micro level is infrequent and large or lumpy the most common explanation for this is that firms face non convex physical adjustment costs the model developed in this paper shows that information costs make investment lumpy at the micro level even in the absence of non convex adjustment costs when collecting and processing information is costly the firm optimally chooses to do it sporadically and to be inactive most of the time this behavior results in infrequent and possibly large capital adjustments the model fits plant level investment rate moments well and it also matches some higher order moments of aggregate investment rates keywords investment dynamics information costs inattentiveness lumpy investment jel classification d21 d83 d92 e22

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

information theoretic approaches in economics economics has seen a recent rise in interest in information theory as an alternative framework to the conventional notion of equilibrium as a fixed state such as walrasian market clearing general equilibrium the information theoretic approach is predicated on the notion of statistical equilibrium se that takes a distribution over all possible states as an equilibrium and therefore predicts the endogenous fluctuations of the system along with its central tendency simultaneously for this reason se approaches can explain the observed data without relying on arbitrary assumptions about random noise and provide useful insights for many interesting economic problems that conventional methods have not been able to satisfactorily deal with in this paper we review the key elements of information theory focusing on the notions and applications of entropy and se in economics particularly paying attention to how entropy concepts open up a new frontline of economic research

macroeconomic expectations and time varying heterogeneity evidence from individual survey data the goal of this paper is to investigate forecast heterogeneity and time variability in the formation of expectations using disaggregated monthly survey data on macroeconomic indicators provided by

price adjustments in a general model of state dependent pricing we study the distribution of retail price adjustments under the assumption that firms are more likely to adjust their prices when doing so is more valuable our setup nests calvo 1983 at one extreme and a fixed menu cost model at the other all parameterizations are ranked by a measure of state dependence high state dependence implies counterfactually that there are no small price changes and that the variance of price changes falls sharply with trend inflation the parameterization that best fits microdata has low state dependence implying a phillips curve coefficient 60 as large as that of the calvo model but is nonetheless well behaved at high inflation rates

optimal central bank transparency should central banks increase their degree of transparency any further we show that there is likely to be an optimal intermediate degree of central bank transparency up to this optimum more transparency is desirable it improves the quality of private sector inflation forecasts but beyond the optimum people might 1 start to attach too much weight to the conditionality of their forecasts and or 2 get confused by the large and increasing amount of information they receive this deteriorates the perceived quality of private sector inflation forecasts as a result inflation is set in a more backward looking manner resulting in higher inflation persistence by using a large scale panel data set on the transparency of central banks we find empirical support for an optimal intermediate degree of transparency at which inflation persistence is minimized our results indicate that while several central banks would benefit from further transparency increases some already have reached the optimal level

focusing effect and the poverty trap abstract i build a dynamic consumption savings model in which agents choices are distorted by the focusing effect agents overweight the utility of goods in which their options differ more i show that the consumption savings choice depends both on the marginal return on savings and on the total return on savings implying that the incentive to save may increase with the initial level of wealth as a consequence a salience based poverty trap may exist when the marginal return on savings is sufficiently high and sufficiently flat i also consider the case of a perfect credit market and show that a poverty trap may emerge when the salience of consumption is bounded above i discuss policy implications in particular imposing upon an agent a punishment for decreasing savings below a threshold leads to a higher level of savings even when the threshold triggering the punishment is not binding

coarse competitive equilibrium and extreme prices we introduce a notion of coarse competitive equilibrium to study agents inability to tailor their consumption to prices our goal is to incorporate limited cognitive ability in particular limited attention memory and complexity into the analysis of competitive equilibrium compared to standard competitive equilibrium our concept yields more extreme prices and when all agents have the same endowment riskier allocations we provide a tractable model suitable for general equilibrium analysis as well as asset pricing

bounded rationality lifecycle consumption and social security abstract this paper explores an overlapping generations model of bounded rationality in which consumers only foresee the future over a subset of their life span we focus in particular on whether the model can in general equilibrium produce a hump shaped lifecycle consumption profile with a peak that matches data for the average u s consumer for a simple four period model we show that an increasing income profile along with exogenously imposed retirement are sufficient to induce a hump with no other mechanism that can account for a hump besides bounded rationality the model best fits the salient features of consumption data with a planning horizon of 20 years which is well supported by the behavioral evidence found in surveys on retirement planning finally we show that the age of the consumption peak is robust to the introduction of social security mortality risk and another species of bounded rationality quasihyperbolic discounting moreover social security can be welfare improving with a short planning horizon we can calibrate the model to jointly explain the timing of the consumption hump and the optimality of the current social security system with quasihyperbolic discounting instead we can calibrate the model so the current social security system is optimal but we cannot also account for the timing of the consumption hump if we add quasihyperbolic discounting in addition to a short planning horizon the present bias has a negligible effect in equilibrium

when little things mean a lot on the inefficiency of item pricing laws abstract item pricing laws ipls require a price tag on every item sold by a retailer we study ipls and assess their efficiency by quantifying their costs and comparing them to previously documented benefits on the cost side we posit that ipls should lead to higher prices because they increase the costs of pricing and price adjustment we test this prediction using data collected from large supermarket chains in the tri state area of new york new jersey and connecticut we find that ipl store prices are higher by about 20 25 per item on average as a control we use data from stores that use electronic shelf labels and find that their prices fall between ipl and no ipl store prices we compare the costs of ipls to existing measures of the benefits and find that the costs are an order of magnitude higher than the upper bound of the estimated benefits

time variation in term premia international survey based evidence using a large previously unexplored data set of survey based interest rate forecasts that covers a broad range of countries this paper re examines the expectations hypothesis of the term structure of interest rates we find that survey based interest rate forecasts outperform not only a random walk forecast but also outperform forecasts from forward rates when using these superior survey based forecasts in a modified expectations hypothesis test the expectations hypothesis is rejected for fewer countries at lower significance levels and has greater explanatory power than when using a traditional forward rates based test we furthermore document strong time variation in the term premia which is an important reason why the traditional expectations hypothesis test is rejected so frequently this time variation seems to arise from the changing attitudes towards risk among market participants and as a compensation for the change in liquidity in the term structure finally we find that generalizing findings from earlier u s studies to other countries may lead to bias in the true economic relationships in these countries

crowdfunding and regional entrepreneurial investment an application of the crowdberkeley database abstract crowdfunding platforms enable individuals to solicit small investments donations or loans over the internet from a wide variety of funders they have emerged as a new and potentially important source of funds for entrepreneurial and philanthropic initiatives we build and present three databases for public use including kickstarter kiva and crowdrise and link regional measures of kickstarter to entrepreneurial ventures listed in crunchbase we find that kickstarter projects in a region correlate with increased angel investing activity even after instrumenting with projects that should not be of interest to investors the paper describes scraping tools database schema descriptive statistics dashboards access for research and policy use and general reflections on building open databases for the research community

risk aversion and wealth evidence from person to person lending portfolios we estimate risk aversion from investors financial decisions in a person to person lending platform we develop a method that obtains a risk aversion parameter from each portfolio choice since the same individuals invest repeatedly we construct a panel data set that we use to disentangle heterogeneity in attitudes toward risk across investors from the elasticity of risk aversion to changes in wealth we find that wealthier investors are more risk averse in the cross section and that investors become more risk averse after a negative housing wealth shock thus investors exhibit preferences consistent with decreasing relative risk aversion and habit formation data as supplemental material are available at http dx doi org 10 1287 mnsc 2015 2317 this paper was accepted by amit seru finance

setting the right prices for the wrong reasons we consider a model of nominal price adjustment with firm specific and aggregate shocks to economic fundamentals and incomplete dispersed information firms update their expectations about fundamentals based on their own cash flows revenues and wages we show that in a model with realistic levels of product level price dispersion the firms inference about aggregate shocks is very gradual yet in the aggregate prices adjust rapidly in response to aggregate nominal shocks when an aggregate shock occurs firms mistakenly attribute it to firm specific shocks but adjust prices nevertheless since the exact nature of the shock matters little for its optimal pricing decision

statistical testing of bounded rationality with applications to the newsvendor model abstract in this paper we define bounded rationality in terms of probabilistic cost efficiency this establishes a framework where bounded rationality can be examined rigorously by statistical methods we apply this theory to data from laboratory experiments on the newsvendor model we enter into a theoretical discussion of the classical pull to center effect and explain why underorders are typically larger than overorders

imperfect common knowledge staggered price setting and the effects of monetary policy this paper studies the consequences of a lack of common knowledge in the transmission of monetary policy by integrating the woodford 2003a imperfect common knowledge model with taylor calvo staggered price setting models the average price set by monopolistically competitive firms depends on their higher order expectations about not only the current state of the economy but also about the states in the future periods in which prices are to be fixed this integrated model provides a plausible explanation for the observed effects of monetary policy it shows analytically how price adjustments are delayed and how the response of output to monetary disturbances is amplified

how quickly do forecasters incorporate news evidence from cross country surveys using forecasts from consensus economics inc we provide evidence on the efficiency of real gdp growth forecasts by testing whether forecast revisions are uncorrelated as the forecast data used are multi dimensional 18 countries 24 monthly forecasts for the current and the following year and 16 target years the panel estimation takes into account the complex structure of the variance covariance matrix due to propagation of shocks across countries and economic linkages among them efficiency is rejected for all 18 countries forecast revisions show a high degree of serial correlation we then develop a framework for characterizing the nature of the inefficiency in forecasts for a smaller set of countries the g 7 we estimate a var model on forecast revisions the degree of inefficiency as mananifested in the serial correlation of forecast revisions tends to be smaller in forecasts of the usa than in forecasts for european countries our framework also shows that one of the sources of the inefficiency in a country s forecasts is resistance to utilizing foreign news thus the quality of forecasts for many of these countries can be significantly improved if forecasters pay more attention to news originating from outside their respective countries this is particularly the case for canadian and french forecasts which would gain by paying greater attention than they do to news from the usa and germany respectively

a new suggestion for simplifying the theory of money we propose a new search theoretic model of monetary exchange with indivisible assets based on price posting instead of bargaining and incorporating noisy search this yields some familiar results plus a lot more the model admits multiple steady states due to the self referential nature of liquidity it admits cyclic chaotic and stochastic equilibria and compared to bargaining versions the dynamics are more general and have better microfoundations it generates price dispersion with interesting efficiency implications plus sticky prices and rational inattention parametric examples yield closed form solutions based on these results we suggest this should become a benchmark model in monetary economics

were there regime switches in u s monetary policy working paper 2004 14 june 2004 abstract a multivariate model identifying monetary policy and allowing for simultaneity and regime switching in coefficients and variances is confronted with u s data since 1959 the best fit is with a model that allows time variation in structural disturbance variances only among models that also allow for changes in equation coefficients the best fit is for a model that allows coefficients to change only in the monetary policy rule that model allows switching among three main regimes and one rarely and briefly occurring regime the three main regimes correspond roughly to periods when most observers believe that monetary policy actually differed and the differences in policy behavior are substantively interesting though statistically ill determined the estimates imply monetary targeting was central in the early 80s but was also important sporadically in the 70s the changes in regime were essential neither to the rise in inflation in the 70s nor to its decline in the 80s jel classification e52 e47 c53 key words counterfactuals lucas critique policy rule monetary targeting simultaneity volatility model comparison i the debate over monetary policy change in an influential paper clarida gali and gertler 2000 cgg presented evidence that us monetary policy changed between the 1970 s and the 1980 s indeed that in the 70 s it was drastically worse they found that the policy rule apparently followed in the 70 s was one that when embedded in most stochastic general equilibrium models would imply non uniqueness of the equilibrium and hence vulnerability of the economy to sunspot fluctuations of arbitrarily large size their estimated policy rule for the later period on the other hand eliminated this indeterminacy these results are a possible explanation of the volatile and rising inflation of the 70 s and of its subsequent decline the cgg analysis has two important weaknesses one is that it fails to account for stochastic volatility us macroeconomic variables and particularly the federal funds rate have gone through periods of tranquility and of agitation with forecast error variances varying greatly from period to period ignoring such variation does not lead to inconsistent estimates of model parameters when the forecasting equations themselves are constant but it strongly biases toward a finding of changed parameters tests of the stability of the forecasting equations the other weakness is that the cgg analysis rests on powerful and implausible identifying assumptions they require that we accept that the response of the monetary authority to expected future inflation and output does not depend on the recent history of inflation money growth or output it is hard to understand why this should be so especially in the 70 s when monetarism was a prominent theme in policy debates congress was requiring reports from the fed of projected time paths of monetary aggregates and financial markets were reacting sensitively to weekly money supply numbers the requirement for existence and uniqueness of equilibrium in dynamic models is that the monetary policy rule show a more than unit response of interest rates to the sum of the logs of all nominal variables that appear on the right hand side of the reaction function if we force a particular measure of expected future inflation to proxy for all the nominal variables that actually appear independently in the reaction function we are bound to get distorted conclusions on the one hand because expected future inflation will be a noisy measure of the full set of nominal influences on policy we might get downward bias in our estimates from the usual errorsin variables effect on the other hand to the extent that expected future inflation like most expected future values shows less variation than current nominal variables we could find a mistaken scaling up of coefficients

sticky prices and costly credit we develop a theory of money and credit as competing payment instruments then put it to work in applications agents use cash and credit because the former latter is subject to the inflation tax transaction costs frictions that make the choice of payment method interesting also imply equilibrium price dispersion we derive closed form solutions for money demand and show how to simultaneously account for the price change facts cash credit shares in micro data and money interest correlations in macro data the effects of inflation on welfare price dispersion and markups are discussed as are nonstationary equilibria with dynamics in the price distribution

evaluating the efficiency of the fomc s new economic projections since 2007 fomc policymakers have been publishing detailed numerical projections of macroeconomic series over the next three years by testing whether the revisions to these projections are unpredictable i find that fomc s efficiency is generally accepted for inflation but often rejected for real economic variables notably for the unemployment rate the rejection is due to the strong autocorrelation of revisions which may reflect information rigidity of fomc s unemployment projections the joint efficiency of the entire projection is accepted in most cases

the puzzling evolution of the home bias information processing and financial openness abstract this paper explains the home equity bias and its puzzling evolution in a model where investors face an information constraint and have an initial local informational advantage after financial liberalization local investors have a magnified informational advantage since information processed under autarky remains useful after liberalization a gradual shift towards foreign assets occurs as the relevance of autarkic information declines over time in the long run home bias remains large due to the interaction between information and portfolio choices empirical evidence supports the main predictions of our model namely that bias increases with information capacity and decreases with financial openness

blue chip rationality tests this paper tests the rationality of forecasts made by individuals who contribute to the blue chip consensus forecasting service and tries by means of a questionnaire on forecasting methods to establish why some forecasters appear more rational than others tests based on consensus forecasts prove unreliable as guides to the number of individuals who produce rational forecasts individual forecasts are more likely to be rational if they are based on a mainstream economic theory and incorporate a substantial element of judgment copyright 1991 by ohio state university press

news and noise in g 7 gdp announcements revisions to gdp announcements are known to be quite large in all g 7 countries quarterly growth rate revisions are regularly more than a full percentage point at an annualized rate we examine the predictability of these revisions using standard statistical tests of whether the preliminary announcement is a rational forecast of the subsequently revised data previous work suggests that u s gdp revisions are largely unpredictable as would be the case if the revisions reflect news not available at the time that the preliminary number is produced we find that the degree of predictability varies throughout the g 7 although we find little predictability in u s revisions the data revisions for several foreign countries are highly predictable we also perform a simple real time forecasting exercise showing that for several countries the predictability of data revision could be used to generate improved preliminary data

sources and propagation of international output cycles common shocks or transmission abstract this paper studies the generation and transmission of international cycles in a multi country model with production and consumption interdependencies two sources of disturbance are considered and three channels of propagation are compared technology disturbances which are mildly correlated across countries are more successful than government expenditure disturbances in reproducing actual data the presence of a common component to the shocks and of production interdependencies appear to be crucial in quantitatively matching the properties of the data

access to finance for innovative smes since the financial crisis in the wake of the 2008 financial crisis there has been increased focus on access to finance for small firms research from before the crisis suggested that it was harder for innovative firms to access finance yet no research has considered the differential effect of the crisis on innovative firms this paper addresses this gap using a dataset of over 10 000 uk sme employers we find that innovative firms are more likely to be turned down for finance than other firms and this worsened significantly in the crisis however regressions controlling for a host of firm characteristics show that the worsening in general credit conditions has been more pronounced for non innovative firms with the exception of absolute credit rationing which still remains more severe for innovative firms the results suggest that there are two issues in the financial system the first is a structural problem which restricts access to finance for innovative firms the second is a cyclical problem has been caused by the financial crisis and has impacted relatively more severely on non innovative firms

testing the behavior of rationally inattentive consumers in a residential water market abstract rationally inattentive consumers tend to apply simplified heuristics when making decisions we test the hypothesis of rational inattention in the context of residential water usage where water bills typically account for a small fraction of household expenditures and only attract casual attention we begin by rigorously testing whether or not residential water customers exhibit evidence of rational inattention we then propose a heuristic water demand model to explore the decision making of rationally inattentive consumers and validate the model by comparing the model with the discrete continuous choice model on attentive and fully informed decision makers in out of sample predictions
