simulating stock returns under switching regimes a new test of market efficiency a model of profits switches between four regimes with fixed probabilities the rationally expected profits stream implies the stock market value this efficient market model is not rejected by uk post war time series behaviour of either profits or the ftse index

international business cycles and risk sharing with uncertainty shocks and recursive preferences this paper analyzes the effects of output volatility shocks on the dynamics of consumption trade flows and the real exchange rate in a two country two good world with consumption home bias recursive preferences and complete financial markets when the risk aversion coefficient exceeds the inverse of the intertemporal substitution elasticity then an exogenous rise in a country s output volatility triggers a wealth transfer to that country to compensate for the greater riskiness of the country s output stream this risk sharing transfer raises the country s consumption lowers its trade balance and appreciates its real exchange rate in the recursive preferences framework here volatility shocks account for a non negligible share of the fluctuations of net exports net foreign assets and the real exchange rate these shocks help to explain the high empirical volatility of the real exchange rate and the disconnect between relative consumption and the real exchange rate

why has u s inflation become harder to forecast we examine whether the u s rate of price inflation has become harder to forecast and to the extent that it has what changes in the inflation process have made it so the main finding is that the univariate inflation process is well described by an unobserved component trend cycle model with stochastic volatility or equivalently an integrated moving average process with time varying parameters this model explains a variety of recent univariate inflation forecasting puzzles and begins to explain some multivariate inflation forecasting puzzles as well

what determines households inflation expectations theory and evidence from a household survey the purpose of the present paper is to study how households form inflation expectations using a novel survey dataset of italian households we extend the existing inattentiveness literature by incorporating explicitly inflation targets and distinguishing between aggregate and disaggregate dynamics based on demographic groups we also consider both the short and long run dynamics as households update their inflation expectations while we find clear distinctions between the various demographic groups behavior households tend to absorb professionals forecast the short run dynamics also indicate they not only overreact when updating their expectations but also adjust asymmetrically to any perceived momentum change of future inflation

can behavioral finance models account for historical asset prices i construct a behavioral model of asset pricing in which agents choose whether to base their expectations on chartist or fundamental forecasts i simulate the model in order to test its efficacy in explaining the moments and time series properties of the ftse all share index and find that the model cannot be rejected as the data generating process

estimates of the sticky information phillips curve for the united states mankiw and reis 2002 have proposed a sticky information based phillips curve sipc to address some of the concerns with the sticky price based new keynesian phillips curve in this paper we present a methodology to empirically implement the sipc and estimate its key structural parameter the degree of information stickiness for the united states using this methodology we estimate average durations of information stickiness that range from three quarters on the low side to over seven quarters on the high side

trend inflation and monetary policy regimes in japan abstract this paper examines the dynamics of trend inflation in japan over the last three decades based on the smooth transition phillips curve model we find that there is a strong connection between the trend inflation and monetary policy regimes the results also suggest that the introduction of the inflation targeting policy and quantitative and qualitative easing in the beginning of 2013 successfully escaped from the deflationary regime but were not enough to achieve the 2 inflation target finally our results indicate the significance of exchange rates in explaining the recent fluctuations of inflation and the importance of oil and stock prices in maintaining the positive trend inflation regime

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

sticky information in general equilibrium this paper develops and analyzes a general equilibrium model with sticky information the only rigidity in goods labor and financial markets is that agents are inattentive sporadically updating their information sets when setting prices wages and consumption after presenting the ingredients of such a model the paper develops an algorithm to solve this class of models and uses it to study the model s dynamic properties it then estimates the parameters of the model using u s data on five key macroeconomic time series it finds that information stickiness is present in all markets and is especially pronounced for consumers and workers variance decompositions show that monetary policy and aggregate demand shocks account for most of the variance of inflation output and hours jel e30 e10

a naive sticky information model of households inflation expectations this paper provides a simple epidemiology model where households when forming their inflation expectations rationally adopt the past release of inflation with certain probability rather than the forward looking newspaper forecast as suggested in carroll 2003 macroeconomic expectations of households and professional forecasters quarterly journal of economics 118 269 298 the posterior model probabilities based on the michigan survey data strongly support the proposed model we also extend the agent based epidemiology model by deriving for it a simple adaptation which is suitable for estimation our results show that this model is able to capture the heterogeneity in households expectations very well

international business cycles with endogenous incomplete markets backus kehoe and kydland 1992 baxter and crucini 1995 and stockman and tesar 1995 find two major discrepancies between standard international business cycle models with complete markets and the data in the models cross country correlations are much higher for consumption than for output while in the data the opposite is true and cross country correlations of employment and investment are negative while in the data they are positive this paper introduces a friction into a standard model that helps resolve these anomalies the friction is that international loans are imperfectly enforceable any country can renege on its debts and suffer the consequences for future borrowing to solve for equilibrium in this economy with endogenous incomplete markets the methods of marcet and marimon 1999 are extended incorporating the friction helps resolve the anomalies more than does exogenously restricting the assets that can be traded

expectations heterogeneous forecast errors and consumption micro evidence from the michigan consumer sentiment surveys the household data underlying the michigan index of consumer sentiment are used to test the rationality of consumer expectations and their usefulness in forecasting expenditure the results can be interpreted as characterizing the shocks that hit different types of households over time expectations are found to be biased and inefficient at least ex post people underestimated the disinflation of the early 1980s and the severity of recent business cycles people s forecast errors are also systematically correlated with their demographic characteristics in part because of time varying group level shocks further sentiment helps forecast consumption growth some of this rejection of the permanent income hypothesis is due to the systematic demographic components in forecast errors

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

taxes and international risk sharing abstract we extend a standard model of international risk sharing to include an empirically plausible distortion taxes the tax inclusive theory implies even under full risk sharing a predictable relationship between consumption growth and the consumption and capital income tax rates both within and across countries we find strong empirical evidence in favor of this relationship while idiosyncratic output fluctuations account for substantially more of cross country consumption growth variability than do taxes trends in tax differentials are found to be informative about the dynamic evolution of international risk sharing in particular adjusting for capital taxes reveals a marked improvement in risk sharing over the last three decades that is absent in baseline measures this improvement has been driven by the convergence of average tax rates on capital income across oecd countries toward the united states average capital tax rate

pareto weights as wedges in two country models abstract in models with recursive preferences endogenous variation in pareto weights would be interpreted as wedges from the perspective of a frictionless model with additive preferences we describe the behavior of the relative pareto weight in a two country world and explore its interaction with consumption and the real exchange rate

dynamics of the trade balance and the terms of trade the j curve the authors provide a theoretical interpretation of two features of international data the countercyclical movements in net exports and the tendency for the trade balance to be negatively correlated with current and future movements in terms of trade but positively correlated with past movements they document the same properties in a two country stochastic growth model in which trade fluctuations reflect in large part the dynamics of capital formation the authors find that their general equilibrium perspective is essential the relation between the trade balance and the terms of trade depends critically on the source of fluctuations copyright 1994 by american economic association

consumption and real exchange rates in dynamic economies with non traded goods abstract we examine the possibility that non traded goods may account for several striking features of international macroeconomic data large persistent deviations from purchasing power parity small correlations of aggregate consumption fluctuations across countries and substantial international real interest rate differentials a dynamic exchange economy is used to show that non traded goods in principle can account for each of these phenomena in the theory there is a close relation between fluctuations in consumption ratios and those in bilateral real exchange rates but we find little evidence for this relation in time series data for eight oecd countries

heterogeneous inflation expectations and learning using the panel component of the michigan survey of consumers we estimate a learning model of inflation expectations allowing for heterogeneous use of private information and lifetime inflation experience life experience inflation has a significant impact on individual expectations but only for 1 year ahead inflation public information is substantially more relevant for longer horizon expectations even controlling for life experience inflation and public information idiosyncratic information explains a nontrivial proportion of the inflation forecasts of agents women ethnic minorities and less educated agents have a higher degree of heterogeneity in their idiosyncratic information and give less importance to recent movements in inflation

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

consumption real exchange rates and the structure of international asset markets abstract international real business cycle irbc models that assume complete asset markets yield strong restrictions for consumption and bilateral real exchange rate series empirical tests with data for the us japan france uk italy canada and sweden suggest that neither the trend behavior nor high frequency movements of consumption and real exchange rates are well explained by irbc models with complete markets it appears however that high frequency fluctuations of consumption and real exchange rates are consistent with unrestricted international trade in risk free bonds

the dynamics of risk sensitive allocations abstract this paper describes pareto optimal allocations when agents have risk sensitive preferences as formulated by hansen and sargent ieee trans automat control 40 5 1995 968 971 necessary and sufficient conditions are given for the existence and stability of steady states at which pareto weights are time invariant when all agents are risk sensitive with the same power reward function there is a unique interior steady state which is stable when the power is positive and unstable when the power is negative when there is at least one agent with time additive preferences eventually all risk sensitive agents have zero pareto weights

does self fulfilment of the inflation expectation exist abstractthis study examines the causal relationship between the actual and expected inflation in the u s using the bootstrap granger full sample causality test and sub sample rolling window estimation test to illustrate the self fulfilment of inflation expectations the full sample result indicates that there is a bidirectional causality between the actual and expected inflation showing the possibility of self fulfilment of inflation expectations which illustrates that inflation is driven by inflation expectation however considering structural changes in two series we find that the short run causal nexus between the actual and expected inflation using full sample data are fraudulent by adopting a time varying rolling window approach to revisiting the dynamic causal relationships this article identifies that the actual inflation has both positive and negative impacts on the expected inflation in distinct sub periods nevertheless inflation expectation exerts only negative effects on the actual inf

the international diversification puzzle is not as bad as you think the international diversification puzzle is the fact that country portfolios are on average biased toward domestic assets while one good international macro models with nondiversifiable labor income risk predict the opposite pattern of diversification this paper embeds a portfolio choice decision in a two good international business cycle model and provides a closed form solution for equilibrium country portfolios equilibrium portfolios are biased toward domestic assets because endogenous international relative price fluctuations make domestic assets a good hedge against labor income risk evidence from developed economies in recent years is qualitatively and quantitatively consistent with the mechanisms highlighted by the theory

new tests of the new keynesian phillips curve abstract lagged dependent variables typically play an important role in empirical models of inflation do these lags reflect backward looking inflation expectations or do they proxy for rational forward looking expectations as in the new keynesian phillips curve gali and gertler 1999 inflation dynamics a structural econometric analysis journal of monetary economics 44 195 222 attempt to answer this question using gmm to estimate specifications incorporating both lagged and future inflation they report small coefficients on lagged inflation and conclude that the new keynesian model provides a good first approximation to inflation dynamics we show that these tests have low power against alternative backward looking specifications and demonstrate that their results are also consistent with a backward looking phillips curve using an alternative approach we find that the new keynesian pricing model cannot explain the importance of lagged inflation in standard inflation regressions and find that forward looking terms play a very limited role in explaining inflation dynamics

the monetary policy implications of behavioral asset bubbles i introduce behavioral asset pricing rules into a wider dynamic stochastic general equilibrium framework asset price bubbles emerged endogenously within the model i find that in this model monetary policy rules that target the mispricing of the asset have a destabilizing effect however a monetary policy rule that targets deviations in the price of the asset from its trend can be welfare enhancing such a rule would also have the benefit of being straightforward to implement

stabilisation policy rational expectations and price level versus inflation targeting a survey we survey literature comparing inflation targeting it and price level targeting pt as macroeconomic stabilisation policies our focus is on new keynesian models and areas that have seen significant developments since ambler s 2009 price level targeting and stabilisation policy a survey journal of economic surveys 23 5 974 997 survey optimal monetary policy the zero lower bound financial frictions and transition costs of adopting a pt regime ambler s conclusion that pt improves social welfare in new keynesian models is fairly robust but we note an interesting split in the literature pt consistently outperforms it in models where policymakers commit to simple taylor type rules but results in favour of pt when policymakers minimise loss functions are overturned with small deviations from the baseline model since the beneficial effects of pt appear to hang on the joint assumption that agents are rational and the economy new keynesian we discuss survey and experimental evidence on rational expectations and the applied macro literature on the empirical performance of new keynesian models overall the evidence is not clear cut but we note that new keynesian models can pass formal statistical tests against macro data and that models with rational expectations outperform those with behavioural expectations i e heuristics in direct statistical tests we therefore argue that policymakers should continue to pay attention to pt

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

macroeconomic forecasting using diffusion indexes this article studies forecasting a macroeconomic time series variable using a large number of predictors the predictors are summarized using a small number of indexes constructed by principal component analysis an approximate dynamic factor model serves as the statistical framework for the estimation of the indexes and construction of the forecasts the method is used to construct 6 12 and 24 monthahead forecasts for eight monthly u s macroeconomic time series using 215 predictors in simulated real time from 1970 through 1998 during this sample period these new forecasts outperformed univariate autoregressions small vector autoregressions and leading indicator models

news on inflation and the epidemiology of inflation expectations this paper examines the nexus between news coverage on inflation and households inflation expectations in doing so we test the epidemiological foundations of the sticky information model carroll 2003 2006 we use both aggregate and household level data from the survey research center at the university of michigan we highlight a fundamental disconnection among news on inflation consumers frequency of expectation updating and the accuracy of their expectations our evidence provides at best weak support to the epidemiological framework as most of the consumers who update their expectations do not revise them toward professional forecasters mean forecast

risk and ambiguity in models of business cycles abstract we inject aggregate uncertainty risk and ambiguity into an otherwise standard business cycle model and describe its consequences we find that increases in uncertainty generally reduce consumption but they do not account in this model for either the magnitude or the persistence of the most recent recession we speculate about extensions that might do better along one or both dimensions
