sticky prices and monetary policy evidence from disaggregated us data this paper disentangles fluctuations in disaggregated prices due to macroeconomic and sectoral conditions using a factor augmented vector autoregression estimated on a large data set on the basis of this estimation we establish eight facts 1 macroeconomic shocks explain only about 15 of sectoral inflation fluctuations 2 the persistence of sectoral inflation is driven by macroeconomic factors 3 while disaggregated prices respond quickly to sector specific shocks their responses to aggregate shocks are small on impact and larger thereafter 4 most prices respond with a significant delay to identified monetary policy shocks and show little evidence of a price puzzle contrary to existing studies based on traditional vars 5 categories in which consumer prices fall the most following a monetary policy shock tend to be those in which quantities consumed fall the least 6 the observed dispersion in the reaction of producer prices is relatively well explained by the degree of market power 7 prices in sectors with volatile idiosyncratic shocks react rapidly to aggregate monetary policy shocks 8 the sector specific components of prices and quantities move in opposite directions

real rigidity nominal rigidity and the social value of information does welfare improve when firms are better informed about the state of the economy and can thus better coordinate their production and pricing decisions we address this question in an elementary business cycle model that highlights how the dispersion of information can impede both kinds of decisions and in this sense be the source of both real and nominal rigidity within this context we develop a taxonomy for how the social value of information depends on the two rigidities on the sources of the business cycle and on the conduct of monetary policy jel d21 d82 d83 e32 e52

booms and busts with dispersed information abstract dispersed information can generate booms and busts in economic activity boom bust dynamics appear when firms are initially over optimistic about demand due to a noisy private news consequently they overproduce which generates a boom and depresses their markups because the news is private firms cannot relate these low markups to aggregate optimism as low markups can also signal low demand this overturns their expectations generating a bust we emphasize a novel role for imperfect common knowledge dispersed information makes firms ignorant about their competitors actions which makes them confuse high noise driven supply with low fundamental demand

compliance with mandatory environmental reporting in financial statements the case of spain 2001 2003 corporate social ethical and environmental reporting seer should ideally discharge the accountability of an organisation to its stakeholders voluntary reporting has been characterised by a dearth of neutral and objective information such that the advocates of seer recommend that it be made compulsory their underlying rationale is that legally specified disclosure requirements and enforcement mechanisms will enhance the quality of such reporting this paper sets out to explore how realistic this scenario actually is in view of the conflicting interpretations in the literature on this subject to that end a survey of the reporting patterns of 78 of the largest spanish companies between 2001 and 2003 examines the extent of their compliance with the icac 2002 standard which obliged them to make environmental disclosures in their financial statements the results suggest that progressive and improved regulation could increase the volume and quality of seer disclosures they also suggest however that persistent non compliance means that the problems associated with voluntary disclosure still exist finally through an impression management perspective the study reveals the diverse strategies ranging from dismissal to concealment that are employed by companies to avoid transparency as regulation improves and enforcement expectations rise it becomes more difficult to dismiss compulsory reporting norms as a result some firms engage in more complex concealment strategies to attain corporate legitimacy depriving stakeholders of regulatory information the latter point serves to reconcile apparently contradictory explanations in the literature as to whether legitimacy theory might explain partial compliance with seer regulation

optimal monetary policy with informational frictions we study optimal policy in a business cycle setting in which firms hold dispersed private information about or are rationally inattentive to the state of the economy the informational friction i

learning from prices public communication and welfare we study the effect of releasing public information about productivity or monetary shocks using a micro founded macroeconomic model in which agents learn from the distribution of nominal prices while a public release has the direct beneficial effect of providing new information it also has the indirect adverse effect of reducing the informational efficiency of the price system we show that the negative indirect effect can dominate thus the public information release may increase uncertainty about the monetary shock and reduce welfare we find that the optimal communication policy is always to release either all or none of the information

imperfect information multiple shocks and policy s signaling role abstract in multiple shock models when agents have imperfect information they attempt to infer a shock s type in addition to its size in this environment monetary policy plays an important signaling role this paper highlights this signaling role by showing that conclusions from imperfect information monetary models are sensitive to the number of shocks included with multiple shocks contractionary monetary policy can initially increase inflation and delay the eventual disinflation moreover multiple shocks can result in destabilizing price flexibility while optimal policy s response to one shock will depend on the existence of other shocks contrary to a typical linear quadratic framework

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

crises and prices information aggregation multiplicity and volatility crises are volatile times when endogenous sources of information are closely monitored we study the role of information in crises by introducing a financial market in a coordination game with imperfect information the asset price aggregates dispersed private information acting as a public noisy signal in contrast to the case with exogenous information our main result is that uniqueness may not obtain as a perturbation from perfect information multiplicity is ensured with small noise in addition we show that a multiplicity may emerge in the financial price itself b less noise may contribute toward nonfundamental volatility even when the equilibrium is unique and c similar results obtain for a model where individuals observe one another s actions highlighting the importance of endogenous information more generally

monetary policy for inattentive economies we offer a contribution to the analysis of optimal monetary policy we begin with a critical assessment of the existing literature arguing that most work is based on implausible models of inflation output dynamics we then suggest that this problem may be solved with some recent behavioral models which assume that price setters are slow to incorporate macroeconomic information into the prices they set a specific such model is developed and used to derive optimal policy in response to shocks to productivity and aggregate demand optimal policy is price level targeting base drift in the price level which is implicit in the inflation targeting regimes currently used in many central banks is not desirable in this model when shocks to desired markups are added optimal policy is flexible targeting of the price level that is the central bank should allow the price level to deviate from its target for a while in response to these supply shocks but it should eventually return the price level to its target path optimal policy can also be described as an elastic price standard the central bank allows the price level to deviate from its target when output is expected to deviate from its natural rate

an informational rationale for action over disclosure abstract the past two decades have seen a considerable increase in the amount of public information provided by policymakers are such disclosures desirable or is it instead preferable to use such information to condition a policy instrument such a tax or an interest rate this paper studies the relative merits of each means to use a policymaker s information in a flexible class of economies that feature dispersed information and payoff and learning externalities i provide conditions for when the exclusive use of a policy instrument or disclosure is optimal i then relate these to differences in the equilibrium and socially optimal use of information i conclude with a series of applications that show how my results apply to common beauty contest models competitive economies and a broad class of macroeconomic models among others

exogenous information endogenous information and optimal monetary policy most of the analysis of optimal monetary policy is conducted with the calvo model this paper studies optimal monetary policy when the slow adjustment of the price level is due to imperfect information by decision makers in firms we consider two models a model with exogenous dispersed information and a rational inattention model in the model with exogenous dispersed information complete stabilization of the price level is optimal after aggregate productivity shocks but not after markup shocks by contrast in the rational inattention model complete stabilization of the price level is optimal both after aggregate productivity shocks and after markup shocks moreover in the model with exogenous dispersed information there is no value from commitment to a future monetary policy by contrast in the rational inattention model there is value from commitment to a future monetary policy because then the private sector can trust the central bank that not paying attention to certain variables is optimal

federal reserve information and the behavior of interest rates this paper tests for the existence of asymmetric information between the federal reserve and the public by examining federal reserve and commercial inflation forecasts it demonstrates that the federal reserve has considerable information about inflation beyond what is known to commercial forecasters it also shows that monetary policy actions provide signals of the federal reserve s information and that commercial forecasters modify their forecasts in response to those signals these findings may explain why long term interest rates typically rise in response to shifts to tighter monetary policy jel e52 e43 d82 asymmetric information between the federal reserve and the public is a phenomenon that is often posited but rarely tested numerous models of central bank behavior for example show that the existence of asymmetric information has important implications for the effectiveness of policy and the consequences of dynamic inconsistency yet there

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

optimal monetary policy with imperfect common knowledge we study optimal nominal demand policy in a flexible price economy with monopolistic competition where firms have imperfect common knowledge about the shocks hitting the economy information imperfections emerge endogenously because firms are assumed to have finite shannon capacity to process information we then ask how policy that minimizes a quadratic objective in output and prices depends on firms processing capacity when price setting decisions of firms are strategic complements we find that policy should nominally accommodate white noise mark up shocks for a large range of capacity values this fi nding is robust to the policy maker observing shocks imperfectly or being uncertain about firms processing capacity when mark up shocks are persistent accommodation may even have to increase in the medium term but has to decrease in the long run thereby generating a hump shaped price response and a slow reduction in output instead when prices are strategic substitutes policy tends to react with nominal demand contractions to mark up shocks in addition there might exist discontinuities between common knowledge equilibria and equilibria with small amounts of imperfect common knowledge

price dispersion private uncertainty and endogenous nominal rigidities this article shows that when agents learn from prices large private uncertainty may result from a small amount of heterogeneity as in a phelps lucas island model final producers look at the prices of their local inputs to infer aggregate conditions however market linkages between islands make the informativeness of local prices endogenous to general equilibrium relations in this context i show that a vanishingly small heterogeneity in local conditions is enough to generate an equilibrium in which prices are rigid to aggregate shocks and transmit only partial information i use this insight as a microfoundation for price rigidity in an otherwise frictionless monetary model and show that even a tiny amount of dispersion in fundamentals can lead to large non neutrality of money

the cyclical behavior of marginal cost and price the author examines the cyclical behavior of price marginal cost margins for u s manufac turing after 1956 short run marginal cost is markedly procyclical this is primarily due to procyclical overtime payments incurred beca use employment is not perfectly flexible in most industries output price fails to respond to the cyclical movement in marginal cost so price marginal cost margins are markedly countercyclical the res ults contradict business cycle theories that explain low production i n a recession by a high real cost of producing they support theories that explain low production in a recession by the inability of firms to sell their output copyright 1987 by american economic association

signalling effects of monetary policy we develop a dynamic general equilibrium model in which the policy rate signals the central bank s view about macroeconomic developments to price setters the model is estimated with likelihood methods on a u s data set that includes the survey of professional forecasters as a measure of price setters inflation expectations this model improves upon existing perfect information models in explaining why in the data inflation expectations respond with delays to monetary impulses and remain disanchored for years in the 1970s u s monetary policy is found to signal persistent inflationary shocks explaining why inflation and inflation expectations were so persistently heightened the signalling effects of monetary policy also explain why inflation expectations adjusted more sluggishly than inflation after the robust monetary tightening of the 1980s

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

the signaling role of policy actions abstract in an economy affected by shocks that are imperfectly known the monetary instrument takes on a dual stabilizing role as a policy response that directly influences the economy and as a vehicle for information that reveals the central bank s assessment to firms because mark up shocks cannot be neutralized by monetary policy providing firms with more information about these shocks exacerbates their reaction and creates a larger distortion recognizing the signaling role of its instrument the central bank distorts its policy response in order to optimally shape firms beliefs while providing firms with more information is always detrimental to the output gap it has a more subtle effect on price dispersion depending on whether information is provided through the transparency channel or through the signaling channel although more transparency is always detrimental to welfare the information that is conveyed by the monetary instrument improves welfare when firms coordination is highly valuable

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

socially optimal coordination characterization and policy implications in recent years there has been a growing interest in macro models with heterogeneity in information and complementarity in actions these models deliver promising positive properties such as heightened inertia and volatility but they also raise important normative questions such as whether the heightened inertia and volatility are socially undesirable whether there is room for policies that correct the way agents use information in equilibrium and what are the wel

optimal monetary policy when information is market generated endogenous i e market generated signals observed by firms have crucial implications for monetary policy when information is endogenous firms gather a demand signal from their market that is both real and nominal as a result the traditional surprise channel of monetary policy is absent instead monetary policy works through a signaling channel as it affects firms information through the demand signal the optimal policy is then the signaling policy i e the policy that maximizes the information content of the demand signal in our setup the signaling policy targets a positive correlation between money supply and prices which emphasizes the natural response of prices to real shocks on the contrary in the more traditional case of exogenous information optimal monetary policy would stabilize prices as it acts through the surprise channel we show that the signaling policy is optimal regardless of the amount of attention that firms pay to central bank communication

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

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

the economic aftermath of resource booms evidence from boomtowns in the american west the current us oil and gas boom is injecting labour capital and revenue into communities near reserves will these communities be cursed with lower long run incomes in the wake of the boom we study the oil boom and bust cycle of the 1970s and 1980s to gain insights using annual data on drilling to identify western boom and bust counties we find substantial positive local employment and income effects during the boom in the aftermath of the bust however we find that incomes per capita decreased and unemployment compensation payments increased relative to what they would have been if the boom had not occurred
