Book Description
Originally published in 1982. This book deals with exchange-rate determination and the implications of floating rate regimes for the time paths of prices and quantities. It develops a class of stochastic equilibrium models of the open economy operating under flexible exchange rates, assuming that agents are endowed with rational expectations but do not possess full current information as to the state of the world. Chapters look at a model’s response to economic disturbances, the effect on non-traded goods, and cyclical variations of the terms of trade. The final chapter considers a model to investigate purchasing parity issues.
Rational Speculation and Exchange Rates

Book Description
In this paper we develop a general equilibrium model of exchange rates where expectations of future variables directly affect the current exchange rate through an 'asset-market' term. This term, which results from the assumptions of incomplete asset markets and segmented product markets, does not appear in most models of exchange rates and it allows for changes in expectations about variables at t+1 to affect the date-t exchange rates without requiring changes in other contemporaneous variables. Therefore, the model has the potential to deliver changes in exchange rates, resulting from rational speculation, without much change in consumption allocations or goods' prices, making it consistent with the common view that exchange rates behave like asset prices. To implement the idea that exchange rates respond to expectations about future economic conditions, we introduce a regime variable governing the covariance structure of shocks to productivity and money growth in each country. Changes in the information variable are intended to generate changes in home and foreign agents' perceptions of the relative risks of holding the nominal asset. The model is roughly consistent with the common view that exchange rates behave like asset prices. However, it does not generate a sufficient degree of rational speculation to explain either observed variation of risk premia in foreign exchange markets or observed variation in exchange rates.

Book Description
How successful is PPP, and its extension in the monetary model, as a measure of the equilibrium exchange rate? What are the determinants and dynamics of equilibrium real exchange rates? How can misalignments be measured, and what are their causes? What are the effects of specific policies upon the equilibrium exchange rate? The answers to these questions are important to academic theorists, policymakers, international bankers and investment fund managers. This volume encompasses all of the competing views of equilibrium exchange rate determination, from PPP, through other reduced form models, to the macroeconomic balance approach. This volume is essentially empirical: what do we know about exchange rates? The different econometric and theoretical approaches taken by the various authors in this volume lead to mutually consistent conclusions. This consistency gives us confidence that significant progress has been made in understanding what are the fundamental determinants of exchange rates and what are the forces operating to bring them back in line with the fundamentals.

Book Description
This thesis consists of three essays that theoretically and empirically investigate the asset pricing and macroeconomic implications of uncertainty shocks, propose new measures for model robustness, explain the joint dynamics on equity excess returns and real exchange rates. In the first chapter, I show that the effect of uncertainty shocks on asset prices and macroeconomic dynamics depends on the degree of risk sharing in the economy and the origin of uncertainty. I develop a general equilibrium model with imperfect risk sharing and two sources of uncertainty shocks: (i) cash-flow uncertainty shocks, which affect the idiosyncratic volatility of firms' productivity, and (ii) growth uncertainty shocks, which affect the idiosyncratic variability of firms' investment opportunities. My model deviates from the neoclassical setting in one respect: firms' investment policies are set by the experts who are subject to a moral hazard problem and thus must maintain an non-diversified ownership stake in the firm. As a result, risk sharing between experts and other investors is imperfect. Limited risk sharing distorts equilibrium investment choices, firm valuation, and prices of risk in equilibrium relative to the frictionless benchmark. In the calibrated model, the risk premium on growth uncertainty shocks is negative under poor risk sharing conditions and positive otherwise. Moreover, the cross-sectional spread in valuations between value and growth stocks loads positively on the growth uncertainty shocks under poor risk sharing conditions and negatively otherwise. Empirical tests support these predictions of the model. The second chapter is based on the joint work Chen, Dou, and Kogan (2015), in which we propose a new quantitative measure of model fragility, based on the tendency of a model to over-fit the data in sample with poor out-of-sample performance. We formally show that structural economic models are fragile when the cross-equation restrictions they impose on the baseline statistical model appear excessively informative about combinations of model parameters that are otherwise difficult to estimate. We develop an analytically tractable asymptotic approximation to our fragility measure which we use to identify the problematic parameter combinations. Using these asymptotic results, we diagnose fragility in asset pricing models with rare disasters and long-run consumption risk. The third chapter is based on the joint work Dou and Verdelhan (2015), which presents a two-good, two-country real model that replicates the basic stylized facts on equity excess returns and real interest rates. In the model, markets are incomplete. In each country, workers cannot participate in financial markets whereas investors trade domestic and foreign stocks, as well as an international bond. The investors' asset positions are subject to a borrowing constraint, along with a short-selling constraint on equity. Foreign and domestic agents differ in their elasticity of inter temporal substitution and in their risk-aversion. A time-varying probability of a global disaster implies time-varying risk premia in asset markets, and therefore large and time-varying expected valuation effects on international asset positions. The model highlights the role of market incompleteness and heterogeneity across countries in accounting for the volatility of equity and debt international capital flows.
Damped Asset Trading in the General Equilibrium Model with Incomplete Asset Markets

Book Description
This paper, written as a chapter for a Handbook of International Economics, reviews developments in the theory of international monetary economics from the late 1960's through the early 1980's. Following a review of the operation of the monetary mechanism of balance of payments adjustment in the context of the Mundell-Fleming model, the paper reviews the more modern analysis of the dynamics of balance of payments adjustment under fixed exchange rates and of exchange rate determination under flexible exchange rates. Beginning with a simple exposition of the monetary mechanism, the model is then extended to incorporate sluggish wage and output adjustments, endogenous monetary policy and sterilization operations, multiplicity of tradable and nontradable goods, large countries, capital mobility and portfolio balance. The review then turns to an exposition of exchange rate theory, starting with the monetary approach to exchange rate determination. Issues discussed in this context include purchasing power parities, nontraded goods, the real exchange rate, currency substitution and the interaction between real and monetary factors in effecting exchange rates. The paper proceeds with a presentation of a more general framework that views the question of exchange rate determination as part of the general theory of the determination of asset prices, and which highlights the unique role of expectations. The general framework is then applied to characterize the interaction between the balance of payments and the equilibrium real exchange rate. The paper concludes with a brief discussion of some empirical issues of exchange rate analysis.
