third country effects on the exchange rate abstract predictive regressions for bilateral exchange rates are typically run on variables from the associated bilateral pairs of countries these regressions characteristically have low explanatory power which leaves room for an omitted variables interpretation we test whether these omitted variables are from third countries when third country macro factors are added to bilateral exchange rate regressions they enter significantly and increase the adjusted r 2 a three country exchange rate model illustrates potential channels for third country spillovers to affect the bilateral rate

seasonality and habit persistence in a life cycle model of consumption summary the allocation of non durable consumers expenditure over the four quarters of the year reflects choices made by consumers implying a utility function exhibiting seasonality incorporating such a function the life cycle model fails to explain fully the observed dynamics in uk seasonally unadjusted data seasonal habit persistence effects are introduced and found to be significant although this generalized model stands up well to testing in a univariate context it fails to exclude a predictive role for lagged income changes seasonality is inherent in many economic time series but it is rarely considered to be an issue of interest in econometric model building rather than explicitly investigating the economics underlying seasonal variation modellers typically try to remove its effects either by using seasonally adjusted data or by including seasonal intercept dummies in their equations the former practice is criticized by wallis 1974 who shows that it may distort the relationship between variab le the latter assumes that the function simply shifts up or down with the season however except for degrees of freedom considerations there seems to be no a priori reason why the same parameters or functional form should apply at different times of the year indeed gersovitz and mackinnon 1978 argue that realistic utility cost or production functions result in models in which seasonal influences cannot be separated out in a simple fashion in the present study seasonality is treated as one of the features to be explained within the economic model thus in the particular application to non durable consumers expenditure it is argued that the allocation of expenditure over the year reflects seasonal tastes and hence seasonality in the underlying utility function the implications of this are explicitly investigated the framework for our analysis is the influential paper by hall 1978 who derives a randomwalk model for real non durable consumers expenditure when rational expectations are combined with a life cycle theory of consumption hall does not investigate seasonality at all and employs seasonally adjusted values in his empirical analysis although subsequent us authors have examined many aspects of this theory the type of data used has rarely been

rare disasters and exchange rates we propose a new model of exchange rates which yields a theory of the forward premium puzzle our explanation combines two ingredients the possibility of rare economic disasters and an asset view of the exchange rate our model is frictionless has complete markets and works for an arbitrary number of countries in the model rare worldwide disasters can occur and affect each country s productivity each country s exposure to disaster risk varies over time according to a mean reverting process ri sky countries command high risk premia they feature a depreciated exchange rate and a high interest rate as their risk premium mean reverts their exchange rate appreciates therefore currencies of high interest rate countries appreciate on average to make the notion of disaster risk more implementable we show how options prices might in principle uncover latent disaster risk and help forecast exchange rate movements we then extend the framework to incorporate two factors a disaster risk factor and a business cycle factor we calibrate the model and obtain quantitatively realistic values for the volatility of the exchange rate the forward premium puzzle regression coefficients and near random walk exchange rate dynamics finally we solve a model of stock markets across countries which yields a series of predictions about the joint behavior of exchange rates bonds options and stocks across countries the evidence from the options market appears to be supportive of the model jel e43 e44 f31 g12 g15

the speculative efficiency hypothesis the hypothesis that forward prices are the best unbiased forecast of future spot prices is often presented in the economic and financial analysis of futures markets this paper considers the hypothesis independently of its implications for rational expectations or market efficiency and in order to stress this fact the term speculative efficiency is used to characterize the state envisaged under the hypothesis if a market is subject to efficient speculation the supply of speculative funds is infinitely elastic at the forward price that is equal to the expected future spot price the expected future spot price is a market price determined as the solution to the underlying rational expectations macroeconomic model although the paper is primarily concerned with testing this hypothesis in the foreign exchange market the methodology introduced in the paper is of general application to all futures markets this abstract was borrowed from another version of this item

an exploration of the forward premium puzzle in currency markets a standard empirical finding is that expected changes in exchange rates and interest rate differentials across countries are negatively related implying that uncovered interest rate parity is violated in the data this article provides new empirical evidence that suggests that violations of uncovered interest rate parity and its economic implications depend on the sign of the interest rate differentially a framework related to term structure models is developed to account for the puzzling relationship between expected changes in exchange rates and interest rate differentials estimation results suggest that a particular term structure model can account for the puzzling empirical evidence article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

exchange rate puzzles and distorted beliefs abstract we propose a new explanation for the foreign exchange forward premium and delayed overshooting puzzles we show that both puzzles arise from a systematic distortion in investors beliefs about the interest rate process accordingly the forward premium is always a biased predictor of future depreciation the bias can be so severe as to lead to negative coefficients in the fama regression delayed overshooting may or may not occur depending upon the persistence of interest rate innovations and the degree of misperception we document empirically the extent of this distortion using survey data for g 7 countries against the u s and find that it is strong enough to account for these irregularities

international risk cycles abstract recent work in international finance suggests that exchange rate puzzles can be accounted for if 1 aggregate uncertainty is time varying and 2 countries have heterogeneous exposures to a world aggregate shock we embed these features in a standard two country real business cycle framework and calibrate the model to equity risk premia in low and high interest rates countries unlike traditional real business cycle models our model generates volatile exchange rates a large currency forward premium excess comovement of asset prices relative to quantities and an imperfect correlation between relative consumption growth and exchange rates our model implies however that high interest rate countries have smoother quantities equity returns and interest rates than low interest rate countries contrary to the data

forward and spot exchange rates in a multi currency world separate literatures study violations of uncovered interest parity uip using regression based and portfolio based methods we propose a decomposition of these violations into a cross currency a between time and currency and a cross time component that allows us to analytically relate regression based and portfolio based facts and to estimate the joint restrictions they put on models of currency returns subject to standard assumptions on investors information sets we find that the forward premium puzzle fpp and the dollar trade anomaly are intimately linked both are driven almost exclusively by the cross time component by contrast the carry trade anomaly is driven largely by cross sectional violations of uip the simplest model that the data do not reject features a cross sectional asymmetry that makes some currencies pay permanently higher expected returns than others and larger time series variation in expected returns on the u s dollar than on other currencies importantly conventional estimates of the fpp are not directly informative about expected returns because they do not correct for uncertainty about future mean interest rates once we correct for this uncertainty we never reject the null that investors expect high interest rate currencies to depreciate not appreciate

disequilibrium buffer stocks and consumers expenditure on non durables the authors examine the importance of a disequilibrium real balance effect on non durable consumers expenditure in the u k using cointegration techniques and the johansen procedure they first establish a desired long run demand function for liquid assets depending on income wealth and a set of interest rates deviations of liquidity from this desired level cause changes in consumption via intertemporal substitution but via its effect on disequilibrium liquidity consumption is modeled in an error correction framework and is also found to depend on income and financial wealth both the disequilibrium liquidity and wealth terms may be picking up the effects of financial liberalization e g mortgage leak on consumption as funds released will be temporarily held in financial assets they also find some evidence that changes in the distribution of income have an independent effect on aggregate consumption copyright 1991 by mit press

intertemporal consumer behaviour in developing countries this paper explores aggregate consumption behaviour in four developing countries under the assumption that consumers planning horizons do not extend over their expected lifetime under certain conditions the resulting moving planning horizon model suggests that changes in current income would exert considerably more influence over current consumer spending than is predicted by forward looking theories of consumption which typically assume that consumers planning horizons coincide with expected lifetime estimation of the model for the group of developing countries provides empirical support for the role of changes in current income in influencing the consumption process the results also reveal that consumers are relatively short sighted sinced the length of the planning period of consumers ranges from just over ten months an important implication of these findings is that policy measures can be effective not only if they influence consumers permanent incomes but also if they affect changes in curr

consumption saving and rational expectations some further evidence for the u k this paper examines implications of the rational expectations permanent income framework for quasi savings using u k data the residual from a cointegrating regression between income and consumption provides the quasi savings series that is used in conjunction with differenced income in a bivariate vector autoregression with associated restrictions and exclusion tests a further implication is that savings should granger cause labor income changes incomes and consumption are found to be cointegrated in levels as a robust result and the bivariate system performs well however savings granger cause labor income changes with a perverse positive sign and exclusion restrictions fail copyright 1989 by royal economic society

commodity trade and the carry trade a tale of two countries persistent interest rate differentials account for much of the currency carry trade profitability commodity currencies offer high interest rates on average while countries that export finished goods tend to have low interest rates we develop a general equilibrium model of international trade and currency pricing where countries have an advantage in producing either basic inputs or final goods in the model domestic production insulates commodity producing countries from global productivity shocks forcing final good producers to absorb them commodity currency exchange rates and risk premia increase with productivity differentials and trade frictions these predictions are strongly supported in the data this article is protected by copyright all rights reserved

the carry trade and fundamentals nothing to fear but feer itself the carry trade is the investment strategy of going long in high yield target currencies and short in low yield funding currencies recently this nave trade has seen very high returns for long periods followed by large crash losses after large depreciations of the target currencies based on low sharpe ratios and negative skew these trades could appear unattractive even when diversied across many currencies but more sophisticated conditional trading strategies exhibit more favorable payos we apply novel within economics binary outcome classication tests to show that our directional trading forecasts are informa tive and out of sample loss function analysis to examine trading performance the critical conditioning variable we argue is the fundamental equilibrium exchange rate feer expected returns are lower all else equal when the target currency is overvalued like traders researchers should incorporate this information when evaluating trading strategies when we do so some questions are resolved negative skewness is purged and market volatility vix is uncorrelated with returns other puzzles remain the more sophisticated strategy has a very high sharpe ratio suggesting market ineciency

time varying risk interest rates and exchange rates in general equilibrium under mild assumptions the data indicate that time varying risk is the primary force driving nominal interest rate differentials on currency denominated bonds this finding is an immediate implication of the fact that exchange rates are roughly random walks a general equilibrium monetary model with an endogenous source of risk variation a variable degree of asset market segmentation can produce key features of actual interest rates and exchange rates in this model the endogenous segmentation arises from a fixed cost for agents to exchange money for assets as inflation varies so does the benefit of asset market participation and that changes the fraction of agents participating these effects lead the risk premium to vary systematically with the level of inflation this model produces variation in the risk premium even though the fundamental shocks have constant conditional variances

consumption and income some simple excercises with panel data this paper reports on the performance of simple versions of the rational expectations permanent income hypothesis of hall 1978 and the error correction approach of davidson et al 1978 in explaining nondurable consumption expenditure from austrian panel data paying particular attention to the characterization of nondurability we examine the parameter restrictions implied by the respective models and then select favoured dynamic consumption income relationship our findings suggest that the models receive limited support only for the narrowest category of nondurables food consumed at home particularly for broader categories the strength of model rejections and the complex dynamic paths observed imply that the models provide an inadequate description of consumption at the micro level

effects of transitory consumption and temporal aggregation on the permanent income hypothesis this paper shows that u s monthly consumption data are consistent with the permanent income hypothesis when transitory consumption and temporal aggregation effects are jointly incorporated into the model in this case a more appropriate representation for the permanent income hypothesis is the integrated moving average ima 1 1 process with a negative ma coefficient rather than the repeatedly rejected random walk process restrictions on the relative importance of transitory and permanent consumption are also discussed with and without measurement errors copyright 1993 by mit press

the term structure of currency carry trade risk premia we nd that average returns to currency carry trades decrease signicantly as the maturity of the foreign bonds increases because investment currencies tend to have small local bond term premia the downward term structure of carry trade risk premia is informative about the temporal nature of risks that investors face in currency markets we show that long maturity currency risk premia only depend on the domestic and foreign permanent components of the pricing kernels since transitory currency risk is automatically hedged by interest rate risk for long maturity bonds our

accounting for forward rates in markets for foreign currency absteract forward and spot exchange rates between major currencies imply large standard deviations of both predictable returns from currency speculation and of the equilibrium price measure the intertemporal marginal rate of substitution representative agent theory with time additive preferences cannot account for either of these properties we show that the theory does considerably better along these dimensions when the representative agent s preferences exhibit habit persistence but that the theory fails to reproduce some of the other properties of the data in particular the strong autocorrelation of forward premiums since the advent of flexible exchange rates in the early 1970s a large body of statistical work has established that forward rates for major currencies are not optimal predictors of future spot rates relevant evidence is reported in studies by baillie lippens and mcmahon 1983 bekaert 1991 bilson 1981 boothe and longworth 1984 cumby 1988 cumby and obstfeld 1984 fama 1984 gregory and mccurdy 1984 hansen and hodrick 1983 hodrick and srivastava 1984 and korajczyk and viallet 1990 a more complete list of references is provided by hodrick 1987 these papers indicate that returns from speculation in forward and spot currency markets are predictable and that the predictable components vary considerably over time a number of alternative explanations have been offered for the predictable variation in foreign currency market excess returns kaminsky 1988 korajczyk 1985 and krasker 1980 suggest that infrequent extreme events may make returns appear predictable in small samples the so called peso problem lewis 1989 argues that rational learning following infrequent changes in the process governing equilibrium prices can explain part of the ex post predictability of currency returns froot and frankel 1989 and froot and thaler 1990 examine the hypothesis that market forecasts of future spot

econometric issues in macroeconomic models with generated regressors the paper critically reviews the literature on the econometric issues raised by the use of generated regressors gr in empirical models the economic rationale for the use of gr is considered with examples being drawn from several macroeconomic examples including new classical macroeconomic ncm models which postulate monetary neutrality various estimation methods are discussed for models which include surprise or unexpected terms and the strengths and weaknesses of each approach are investigated drawing upon the work of mcaleer and mckenzie 1991 situations where the typically inefficient two step estimation 2se method will be efficient are highlighted problems of model misspecification and measurement errors are also investigated an empirical section highlights some of the dangers of using uncorrected 2se estimation results through a careful consideration of many recent attempts to test the ncm monetary neutrality hypothesis copyright 1993 by blackwell publishers ltd

aggregate consumption and the distribution of income in the united kingdom an econometric analysis blinder i975 explained this omission by arguing that with the ascendancy of the friedman 1957 and modigliani and brumberg i954 models of consumer behaviour the view that income distribution affected aggregate consumption fell into disrepute in academic circles it was supplanted by the view that marginal and perhaps even average propensities to consume are constant over the income distribution pp 447 8 the life cycle model as is well known derives the aggregate consumption function from the hypothesis that the consumer chooses the time path of consumption which maximises lifetime utility subject to the constraint that the present discounted value of all consumption plus the present discounted value of the bequest if any is equal to lifetime disposable resources a consequence of such a hypothesis is that consumption at each instant is proportional to lifetime disposable resources with the constant of proportionality dependent only on age length of life the rate of interest and tastes in their empirical work friedman and modigliani may also have had to ignore income distribution due to lack of data however blinder 1975 went on to show that even under the life cycle hypothesis provided that the marginal utility of bequests say f was different

trade network centrality and currency risk premia i uncover an economic source of exposure to global risk that drives international asset prices countries that are more central in the global trade network have lower interest rates and currency risk premia to explain these findings i present a general equilibrium model in which central countries consumption growth is more exposed to global consumption growth shocks this causes the currencies of central countries to appreciate in bad times resulting in lower interest rates and currency risk premia empirically central countries consumption growth covaries more with world consumption growth further validating the proposed mechanism

a nonparametric test of the life cycle rational expectations hypothesis in a world of perfect certainty and perfect capital markets agents allocate expenditure in such a way that the marginal utility of discounted expenditure is the same in each period in this paper we present a test of whether any particular series of discounted prices and quantities can be exactly reconciled with a utility function and marginal utility of discounted expenditure that do not change from period to period we find that uk us and canadian postwar aggregate data all reject our condition although it is not rejected for long sub periods we show that our results for the uk suggest particular modifications to the strong form of the rational expectations hypothesis that our condition tests in fact these data are exactly consistent with a number of alternative hypotheses from this we argue that time series data are ill suited to parametric testing of any of the competing hypotheses on the inter temporal allocation of expenditure the pure theory of the inter temporal allocation of goods and time with perfect capital markets and perfect foresight is identical to the static demand case there is a single lifetime budget constraint and the allocation of expenditure to each period is made so that the marginal utility of discounted expenditure is the same in each period bewley 1977 and hall 1978 have identified the life cycle rational expectations hypothesis under uncertainty reh with the proposition that expected utility maximising consumers will allocate expenditures and time in such a way as to try and keep the marginal utility of discounted money constant given a set of time series on prices purchases wages and labor supply we can ask whether these realised plans are consistent with the life cycle hypothesis in this paper we propose a test that requires no ad hoc specification of functional forms or error processes but rather gives an answer yes or no based on finite mathematical techniques the specific hypothesis we test is a strong form of the reh viz that the marginal utility of discounted expenditure is constant over the period of observation for long time series this seems to be an absurdly strong hypothesis since it is effectively equivalent to assuming perfect capital markets and perfect foresight with regard to all important variables if however we can accept this strong hypothesis for a particular data set then any test of the weaker forms of the life cycle rational expectations hypothesis on this data set must be interpreted

survey expectations in the time series consumption function this paper introduces survey based measures of expectations and uncertainties about income and real interest rates into an otherwise conventional consumption function the survey dat a contribute more than conventional variables to the explanation of changes in consumption the hypothesis that consumption follows a random walk is rejected in favor of a model in which consumption responds with a lag to changes in expected income growth the significance of inflation in earlier estimates of the u s consumpti on function is shown to be spurious and due to a strong negative correlation between expected inflation and expected income growth copyright 1992 by mit press

stochastic life cycle theory with varying interest rates and prices incorporating the assumption of rational expectations has produced some striking new predictions from many familiar economic theories one of the benefits of this development is that these new predictions provide additional means of testing well documented theories without necessarily requiring new data though it must be admitted that this is at the cost of an additional and for many a controversial assumption in his paper on life cycle and permanent income theory hall 1978 has given a very good example of such new predictions he demonstrated that if consumers are assumed to measure wealth using rational expectations of future income rather than a distributed lag of past income then a logical consequence of standard life cycle theory is that consumption will closely follow a first order autoregression subsequently bilson 1980 and flavin 1981 showed that the disturbance term in this autoregression will depend on the errors in predicting current and future income at first sight this remarkable result may seem to be inconsistent with the standard consumption function which relates consumption to income but an example will help explain why there is no necessary conflict consider the simple consumption function or absolute income hypothesis

financial intermediation international risk sharing and reserve currencies abstract i model the equilibrium risk sharing between countries with varying financial development the most financially developed country takes greater risks because its financial intermediaries deal with funding problems better in good times the more financially developed country consumes more and runs a trade deficit financed by the higher financial income that it earns as compensation for taking greater risk during global crises it suffers heavier losses its currency emerges as the reserve currency because it appreciates during crises thus providing a good hedge i provide evidence that financial net worth plays a crucial role in understanding this asymmetric risk sharing jel e44 f14 f32 g01 g15 g21

motor fuel taxation energy conservation and economic development a regional approach abstract combustion of motor fuels has a variety of environmental impacts on local regional and global scales taxing motor fuels more heavily would mitigate those environmental impacts however many governments are reluctant to increase motor fuel taxes because they fear that the tax incidence will be regressive and that economic development will be impeded using data for the new england region of the united states this paper argues that an oil importing region can conserve energy avoid regressive impacts and encourage economic development by taxing motor fuels more heavily and rebating the incremental revenues to owners of motor vehicles

the sensitivity of consumption to transitory income estimates from panel data on households we investigate the stochastic relation between income and consumption specifically consumption of food within a panel of about 2 000 households our major findings are 1 consumption responds much more strongly to permanent than to transitory movements of income 2 the response to transitory income is nonetheless clearly positive 3 a simple test independent of our model of consumption rejects a central implication of the pure life cycle permanent income hypothesis the observed covariation of income and consumption is compatible with pure life cycle permanent income behavior on the part of80 percent of families and simple proportionality of consumption and income among the remaining 20 percent as a general matter our findings support the view that families respond differently to different sources of income variations in particular temporary income tax policies have smaller effects on consumption than do other more permanent changes in income of the same magnitude this abstract was borrowed from another version of this item

the time variation of risk and return in foreign exchange markets a general equilibrium perspective this article successively introduces variable velocity durability and habit persistence in a standard two country general equilibrium model and explores their effects on the variability of exchange rate changes forward premiums and the foreign exchange risk premium a new feature of the model is that agents make decisions at a weekly frequency and face conditionally heteroskedastic shocks nevertheless even the most complex model fails to deliver sufficiently variable risk premiums without causing forward premiums and exchange rates to be excessively variable unlike previous models the model can roughly match the persistence of forward premiums article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

determinants of consumption and savings behavior in developing countries the determinants of savings generally and the specific effects of government policies on savings and consumption are pivotal forces in investment and economic growth the hall hypothesis states that consumption is a function of lifetime permanent income rather than income in each period independently changes in interest and tax rates money supply or government expenditure will affect permanent income and hence consumption and savings only if they are unexpected and thus not already incorporated in the estimation of permanent income we are unable to reject the hall hypothesis in tests for developing countries when we allow for varying interest rates we do find evidence of a negative effect of inflation on consumption and a positive relationship between the real interest rate and consumption the evidence for the hall hypothesis also suggests that ricardian equivalence may be valid this is barro s hypothesis that the effect on savings is the same whether government deficits are financed through taxation or debt our preliminary testing however does not support ricardian equivalence savings is the part of one s current income that is not spent on current consumption and it constitutes a large part of a nation s aggregate savings and investment and thus is a major determinant of the growth of future income and consumption households balance the tradeoffs between current and future consumption possibilities when making their individual consumption decisions understanding the determinants of households consumption behavior has been central to macroeconomics the three main theoretical approaches to this issue are keynesian consumption theory the life cycle permanent income hypothesis under rational expectations and the theory of the infinitely lived agent or altruistically linked consumers the theories differ in the extent to which they explain the observed consumer behavior and in their predictions regarding the effects of government policies on individual savings behavior for instance increased taxes higher nominal interest rates or an increase in the money

surprises in the consumption function the life cycle hypothesis has been the dominant theoretical basis for empirical work on the aggregate consumption function for about a quarter of a century under it real consumption is proportional to real life cycle wealth where the factor of proportionality depends on real interest rate expectations and the demographic structure of the population life cycle wealth is the sum of financial and human wealth however because the latter is the present real value of the stream of labour and transfer income expected over the life cycle it is not directly observable this fact has led to a great variety of proxying devices in empirical applications and in consequence much looseness in the interpretation of very different models as being all consistent with life cycle theory indeed one can argue that this has protected the hypothesis from being seriously tested and perhaps rejected an insight associated with friedman 1957 is that the view taken by consumers of life cycle income does not alter by much from period to period since there is greater persistence in life cycle income than in current income this also explains the greater persistence of consumption than of current income intuitively this would suggest that lagged consumption being related to last period s perception of life cycle income which in turn is not much different from this period s perception should have a major role in predicting current consumption this intuition was formalised by hall 1978 using ideas familiar from the study of stock market prices and the term structure of interest rates hall showed that if the real rate of interest is constant and given a number of other assumptions including no transitory element in consumption then the life cycle hypothesis implies that

an economic evaluation of empirical exchange rate models this paper provides a comprehensive evaluation of the short horizon predictive ability of economic fundamentals and forward premiums on monthly exchange rate returns in a framework that allows for volatility timing we implement bayesian methods for estimation and ranking of a set of empirical exchange rate models and construct combined forecasts based on bayesian model averaging more importantly we assess the economic value of the in sample and out of sample forecasting power of the empirical models and find two key results 1 a risk averse investor will pay a high performance fee to switch from a dynamic portfolio strategy based on the random walk model to one that conditions on the forward premium with stochastic volatility innovations and 2 strategies based on combined forecasts yield large economic gains over the random walk benchmark these two results are robust to reasonably high transaction costs

monetary policy and global banking when central banks adjust interest rates the opportunity cost of lending in local currency changes but absent frictions there is no spillover effect to lending in other currencies however when equity capital is limited global banks must benchmark domestic and foreign lending opportunities we show that in equilibrium the marginal return on foreign lending is affected by the interest rate differential with lower domestic rates leading to an increase in local lending at the expense of a reduction in foreign lending we test our prediction in the context of changes in interest rates in six major currency areas

inflation and the euler equation approach to consumption behaviour some empirical evidence abstract by using u s quarterly data on non durable consumption over the period 1951 i 1986 ii this note presents various pieces of evidence for the view that inflation variables in the anticipated surprise and uncertainty forms matter in the euler type consumption autoregression inflation variables are not only significantly negative and make the overall performance of the euler type specifications better but they also induce the wrong sign for the real rate of interest these results are puzzling and suggest that the question of why in contrast with a fisherian intertemporal optimization inflation matters in the consumption autoregression should be an important area for research

asset prices and real exchange rates with deep habits i introduce an external habit for each consumption good known as deep habits into an otherwise standard international equilibrium model with multiple consumption goods and multiple countries i show that deep habits coupled with consumption home bias account for a wide range of asset pricing and exchange rate moments calibrated to a set of ten countries the model reproduces the cross sectional evidence on currency risk premiums when sorting on interest rates interest rate volatility innovations to global exchange rate volatility and value hence the model provides an equilibrium interpretation of these empirical regularities

the intertemporal allocation of expenditure on non durables services and durables this paper presents estimates of the parameters of a consumption function for u s quarterly seasonally unadjusted data on non durables services and durables the theoretical novelty in the approach we present is in the derivation of the consumption function from an underlying many goods allocation problem applying this model with an appropriate estimator to the data we find i the homogeneity restrictions suggested by theory are not rejected ii there is no evidence of excess sensitivity to income iii there is no evidence to suggest that agents cannot adjust their durable stocks as they would wish and iv the intertemporal substitution elasticity is not well determined

country size currency unions and international asset returns differences in real interest rates across developed economies are puzzlingly large and persistent i propose a simple explanation bonds issued in the currencies of larger economies are expensive because they insure against shocks that affect a larger fraction of the world economy i show that indeed differences in the size of economies explain a large fraction of the cross sectional variation in currency returns the data also support additional implications of the model the introduction of a currency union lowers interest rates in participating countries and stocks in the nontraded sector of larger economies pay lower expected returns

surprises in the consumption function incomplete current inflation and moving average errors a note in an important paper hall i978 demonstrated that the joint assumptions of the life cycle hypothesis rational expectations and the constancy of the real rate of interest give rise to the startling implication that the flow of real consumption should only be related to its value in the previous period and a random error this error reflects new information which accrues between the previous and current period formally

good carry bad carry we distinguish between good and bad carry trades constructed from group of ten g 10 currencies the good trades exhibit higher sharpe ratios and sometimes positive return skewness in contrast to the bad trades which have both substantially lower sharpe ratios and highly negative return skewness surprisingly good trades do not involve the most typical carry currencies like the australian dollar and japanese yen the distinction between good and bad carry trades significantly alters our understanding of currency carry trade returns and invalidates for example explanations invoking return skewness and crash risk

investor overconfidence and the forward premium puzzle we offer an explanation for the forward premium puzzle in foreign exchange markets based upon investor overconfidence in the model overconfident individuals overreact to their information about future inflation which causes greater overshooting in the forward rate than in the spot rate thus when agents observe a signal of higher future inflation the consequent rise in the forward premium predicts a subsequent downward correction of the spot rate the model can explain the magnitude of the forward premium bias and several other stylized facts related to the joint behaviour of forward and spot exchange rates our approach is also consistent with the availability of profitable carry trade strategies

which fundamentals drive exchange rates a cross sectional perspective standard present value models suggest that exchange rates are driven by expected future fundamentals implying that exchange rates contain information about future fundamentals we test this key empirical prediction of present value models in a sample of 35 currency pairs ranging from 1900 to 2009 employing a variety of tests we find that exchange rates have strong and significant predictive power for nominal fundamentals inflation money balances nominal gdp whereas predictability of real fundamentals and risk premia is much weaker and largely confined to the post bretton woods era overall we uncover ample evidence that future macro fundamentals drive current exchange rates

aggregate consumption behaviour and liquidity constraints the canadian evidence this paper considers a general permanent income model in which a fraction of consumers in the economy is liquidity constrained consumption growth rate for these individuals is related to the growth rate of their income and the level of real interest rates the interest rate coefficient is predicted to be smaller in the presence of liquidity constraints empirically liquidity constraints are found to be important and the estimated intertemporal elasticity of substitution parameter is much larger than the one obtained by estimating the standard representative agent model lastly there is some evidence of structural changes over the sample period which are associated with the 1982 recession
