global fixed income investments the persistence effect critical consequences flow from accepting or rejecting the view that forward rates predict future yield curve shapes and currency exchange rates a persistence factor reflects the expectation that interest rates will persist at their current levels rather than evolving into their forward rates a persistence assumption of 1 anticipates that spot rates will persist and a persistence assumption of zero anticipates that they will give way to forward rates a global investor with a persistence assumption of zero for all rates faces uniformly flat expected return curves and has no incentive to seek higher returns by accepting duration or currency risk an investor with a persistence factor of 1 anticipates rewards for accepting risks by extending duration along positive yield curves or making unhedged investments in higher yielding currencies for example investors often depend on implicit expectations of this type the persistence model can make such expectations explicit and aid in evaluating their credibi

the turning black tide energy prices and the canadian dollar the authors revisit the relationship between energy prices and the canadian dollar in the amano and van norden 1995 equation which shows a negative relationship such that higher real energy prices lead to a depreciation of the canadian dollar

the structure of unemployment we test for a unit root in postwar unemployment rates for sixteen oecd countries when a one time structural break is incorporated the unit root hypothesis can be rejected for most of the countries and the measured persistence of unemployment falls dramatically we then test for multiple structural changes and find evidence of one or two breaks for those countries for which the unit root hypothesis could be rejected almost all of the breaks are positive reflecting the sustained rise in european unemployment the major exception is the united states where long term unemployment rose in the 1970s and fell in the 1980s

on the international spillovers of us quantitative easing this article analyses the effects of the federal reserve s quantitative easing qe on global portfolio flows differentiating across recipient region of the flows type of flow and qe rounds furthermore the analysis differentiates between the impact of qe expansionary announcements and the actual market operations the analysis shows that qe1 resulted in slight rebalancing towards the us while qe2 and qe3 resulted in rebalancing towards non us assets this suggests that qe increased the pro cyclicality of flows outside the us in particular into emerging market equities the results also suggest a link between us macro financial conditions and the transmission of qe to portfolio flows

a test for moral hazard in the labor market contractual arrangements effort and health moral hazard plays a central role in many models depicting contractual relationships involving worker effort the authors show how time series information on worker health consumption and work time can be used to measure the effort effects of payment schemes estimates from longitudinal data describing farming rural households indicate that time wage payment schemes and share tenancy contracts reduce effort compared to piece rate payment schemes and on farm employment the evidence also indicates consistent with moral hazard that the same workers consume more calories under a piece rate payment scheme or in on farm employment than when employed for time wages copyright 1994 by mit press

optimal inattention to the stock market with information costs and transactions costs recurrent intervals of inattention to the stock market are optimal if consumers incur a utility cost to observe asset values when consumers observe the value of their wealth they decide whether to transfer funds between a transactions account from which consumption must be financed and an investment portfolio of equity and riskless bonds transfers of funds are subject to a transactions cost that reduces wealth and consists of two components one is proportional to the amount of assets transferred and the other is a fixed resource cost because it is costly to transfer funds the consumer may choose not to transfer any funds on a particular observation date in general the optimal adjustment rule including the size and direction of transfers and the time of the next observation is state dependent surprisingly unless the fixed resource cost of transferring funds is large the consumer s optimal behavior eventually evolves to a situation with a purely time dependent rule with a constant interval of time between observations this interval of time can be substantial even for tiny observation costs when this situation is attained the standard consumption euler equation holds between observation dates if the consumer is sufficiently risk averse

caveat emptor cross country data on education and the labor force abstract cross country data on education and the labor force frequently are used to describe important dimensions of development and to estimate models of economic growth and growth determinants the impact of education and related phenomena this investigation finds 1 there are serious intertemporal and inter country comparability problems with these data that may importantly affect inferences about labor force size trends and productivity and schooling investments and impact 2 data gaps are systematically related to levels of development and literacy and 3 conclusions about the determinants or consequences of development based on constructed data that have been made available to fill data gaps can be seriously misleading

discrete actions in information constrained decision problems individuals are constantly processing external information and translating it into actions this draws on limited resources of attention and requires economizing on attention devoted to signals related to economic behaviour a natural measure of such costs is based on shannon s channel capacity modelling economic agents as constrained by shannon capacity as they process freely available information turns out to imply that discretely distributed actions and thus actions that persist across repetitions of the same decision problem are very likely to emerge in settings that without information costs would imply continuously distributed behaviour we show how these results apply to the behaviour of an investor choosing portfolio allocations as well as to some mathematically simpler tracking problems that illustrate the mechanism trying to use costs of adjustment to explain stickiness of actions when interpreting the behaviour in our economic examples would lead to mistaken conclusions

the portfolio of euro area fund investors and ecb monetary policy announcements abstract this paper studies the impact of major ecb monetary policy announcements on the portfolio allocation of euro area fund investors using daily data between 2012 and mid 2016 a period that includes a variety of unconventional measures we distinguish between active portfolio reallocation driven by redemptions or injections of investors and passive portfolio rebalancing triggered by valuation effects related to changes in asset prices and exchange rates we find that for this class of fund investors policy announcements work mainly through valuation effects the signalling channel rather than via active reallocation the portfolio balance channel notably since the autumn of 2014 monetary policy shocks triggered large asset price and exchange rate effects and prompted a passive shift of euro area investors into riskier assets in particular european and emerging market equity funds and out of bond funds

momentum investment strategies portfolio performance and herding a study of mutual fund behavior this study analyzes the extent to which mutual funds purchase stocks based on their past returns as well as their tendency to exhibit herding behavior i e buying and selling the same stocks at the same time the authors find that 77 percent of the mutual funds were momentum investors buying stocks that were past winners however most did not systematically sell past losers on average funds that invested on momentum realized significantly better performance than other funds the authors also find relatively weak evidence that funds tended to buy and sell the same stocks at the same time copyright 1995 by american economic association

financial innovation and the transactions demand for cash we document cash management patterns for households that are at odds with the predictions of deterministic inventory models that abstract from precautionary motives we extend the baumol tobin cash inventory model to a dynamic environment that allows for the possibility of withdrawing cash at random times at a low cost this modification introduces a precautionary motive for holding cash and naturally captures developments in withdrawal technology such as the increasing diffusion of bank branches and atm terminals we characterize the solution of the model which qualitatively reproduces several empirical patterns we estimate the structural parameters using micro data and show that quantitatively the model captures important economic patterns the estimates are used to quantify the expenditure and interest rate elasticity of money demand the impact of financial innovation on money demand the welfare cost of inflation and the benefit of atm ownership

determinants of the intrahousehold allocation of food in the rural philippines this study shows that the opportunity cost of time for husbands and wives can affect the intrahousehold distribution of food in a developing country equations which explain the relative allocation of calories within households were estimated for husbands wives and children with data for the rural philippines the estimating equation is derivable from both a joint household utility function and a bargaining model because the same households were included in the four survey rounds the various observations for a given individual were averaged for each variable in the estimation procedure wages were estimated using the heckman approach

productivity health and inequality in the intrahousehold distribution of food in low income countries a model is formulated incorporating linkages among nutrition labor market productivity health heterogeneity and the intrahousehold distribution of food and work activities in a subsistence economy empirical results based on a sample of households from bangladesh indicate that despite considerable intrahousehold disparities in calorie consumption households are averse to inequality furthermore consistent with the model the results also indicate that both the higher level and greater variance in the calories consumed by men relative to women reflect in part the greater participation by men in activities in which productivity is sensitive to health status copyright 1990 by american economic association

conditional hedging and portfolio performance simple conditional currency hedging rules often increase risk adjusted portfolio returns and are thus of interest to investors several researchers have reported successful application of a forward hedge rule fhr in which one hedges whenever the foreign currency trades at a forward premium an alternative strategy a real interest rate hedge rule rir is based on hedging when the domestic real interest rate exceeds the foreign rate as an extension we propose a combination of these rules a real forward hedge rule rfhr we evaluate the performance of the rules for various currency stock and bond portfolios from the developed countries in tests of risk adjusted returns for 1976 1997 the rfhr significantly outperformed standard benchmarks and often beat the fhr and the rir moreover results of a simple dominance test for rolling 5 and 10 year periods suggest that the rfhr consistently improves portfolio performance for a u s investor

the demand for money financial innovation and the welfare cost of inflation an analysis with household data we use microeconomic data on households to estimate the parameters of the demand for currency derived from a generalized baumol tobin model our data set contains information on average currency deposits and other interest bearing assets the number of trips to the bank the size of withdrawals and ownership and use of atm cards we model the demand for currency accounting for adoption of new transaction technologies and the decision to hold interest bearing assets the interest rate and expenditure flow elasticities of the demand for currency are close to the theoretical values implied by standard inventory models however we find significant differences between individuals with an atm card and those without the estimates of the demand for currency allow us to calculate a measure of the welfare cost of inflation analogous to bailey s triangle but based on a rigorous microeconometric framework the welfare cost of inflation varies considerably within the population but never turns out to be very lar

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

the demand of liquid assets with uncertain lumpy expenditures abstract we consider an inventory model for a liquid asset where the per period net expenditures have two components one that is frequent and small and another that is infrequent and large we give a theoretical characterization of the optimal management of liquid asset as well as of the implied observable statistics we use our characterization to interpret some aspects of households currency management in austria as well as the management of demand deposits by a large sample of italian investors

looking for boy girl discrimination in household expenditure data the ability to test for discrimination in the allocation of goods between boys and girls is hampered by a lack of data on intrahousehold distribution the analysis presented here allows inferences about intrahousehold allocation to be made from householdlevel expenditure data for a given level of income families with children will spend less on adult goods in order to purchase children s goods if household purchasing favors boys over girls smaller expenditures on adult goods would be made by families with boys as compared with those with girls a method for determining adult goods is described and the procedure for detecting gender bias is applied to data from c6te d lvoire and thailand the data show no evidence of discriminatio n between boys and girls in c6te d lvoire and a small and statistically insignificant bias in favor of boys in thailand how commodities are allocated among the members of a household has recently occasioned a good deal of interest assessments of poverty and income distribution based on household incomes or expenditures will be misleading if allocation within the household is unequal the position of women and girls has been of particular concern and there is a considerable amount of empirical evidence much of it from the indian subcontinent that documents discrimination against females see in particular bhagwati 1973 sen 1984 sen and sengupta 1983 miller 1981 bardhan 1982 and kynch and sen 1983 as well as survey papers by behrman 1987 and harriss 1987 much of the evidence is concerned with measurements of nutritional outcomes mortality and health status rather than with the direct allocation of goods by gender the difficulty in trying to determine the intrahousehold allocation of goods is that household budget surveys the obvious source of data record consumption not of individuals but of households and while attempts can be made to the author is a professor of public affairs and of economics and international affairs at princeton university and is a consultant to the population and human resources department of the world bank the author thanks dwayne benjamin who provided for excellent research assistance he is grateful to him and to members of the economic growth center at yale university for helpful comments this is a revised and shortened version of living standards measurement study working paper 39 the allocation of goods within the household adults children and gender june 1987 the results from thailand were not included in the working paper 1989 the international bank for reconstruction and development the world bank

optimal inattention to the stock market inattentive agents update their information sporadically and thus respond belatedly to news we generate optimally inattentive behavior by assuming that to observe the value of his investment portfolio the consumer must pay a cost that is proportional to the portfolio s contempo raneous value it is optimal for the consumer to check his investment portfolio at equally spaced points in time consuming from a riskless trans actions account in the interim the riskless transactions account that finances consump tion guarantees that funds are never unwittingly exhausted we show that the optimal interval of time between consecutive observations of the value of the portfolio is the unique positive solution to a nonlinear equation quantitatively even a small observation cost one basis point of wealth implies a substantial eight month decision interval under conventional parameter values

the new econometrics of structural change dating breaks in u s labor productivity we have seen the emergence of three major innovations in the econometrics of structural change in the past fifteen years 1 tests for a structural break of unknown timing 2 estimation of the timing of a structural break and 3 tests to distinguish unit roots from broken time trends these three innovations have dramatically altered the face of applied time series econometrics in this paper we review these three innovations and illustrate their application through an empirical assessment of u s labor productivity in the manufacturing durables sector

the effect of the value of time on food consumption patterns in developing countries evidence from sri lanka this study shows that the opportunity cost of women s time can affect household food consumption patterns in developing countries demand equations for rice bread and the ratio of bread to total cereal consumption are estimated for urban sri lankan households the demand specification which is based on the new household economics includes as explanatory variables the woman s estimated market wage and the household s full income and alternatively observed income wages are estimated using the heckman procedure to correct for sample selection bias

equilibrium pricing and trading volume under preference uncertainty information collection processing and dissemination financial institutions is challenging this can delay the observation by traders of the exact capital charges and constraints of their institution during this delay traders face preference uncertainty in this context we study optimal trading strategies and equilibrium prices in a continuous centralized market we focus on liquidity shocks during which preference uncertainty is likely to matter most preference uncertainty generates allocative ineficiency but need not reduce prices traders progressively learning about the preferences of their institution conduct round trip trades which generate excess volume relative to the frictionless market in a cross section of liquidity shocks the initial price drop is positively correlated with total trading volume across traders the number of round trips is negatively correlated with trading profits and average inventory

tactical currency allocation market efficiency depends upon rational profit motivated investors two of the largest communities of currency traders have no profit motive central banks trade to dampen volatility corporations seek to hedge the currency exposure in their book of business currency profits are based not on the movement of the currency but on the movement of the currency relative to the forward rate the forward rate is in turn based upon interest rates if an overseas market has a lower interest rate than the domestic market its currency will trade at enough of a premium in the forward market to equalize the interest rates when they are currency hedged but if an overseas market is trading at a lower interest rate than the domestic rate investment capital will typically be siphoned away from the lower yielding market into the higher yielding market driving its currency down even as its forward rate points up central banks tendency to intervene to dampen currency volatility has the effect of introducing serial correlation if a currency that would have rallied 10 rallies only 5 because of government intervention it will rally by 5 later there is a statistically significant pattern a currency that has gone up will more likely than not continue to rally and vice versa

transactions costs and portfolio choice in a discrete continuous time setting abstract this paper makes the following observation concerning a new formulation of the consumption and portfolio choice model of merton 1971 with transaction costs suppose an investor observes his or her current wealth only when making a transaction that transactions are costly and that decisions to transact can be made at any time based on all current information if at each transaction the agent is charged a fixed fraction of current portfolio value an optimal policy exists and the optimal interval of time between transactions is fixed independent of time and current wealth

monetary shocks in models with observation and menu costs we study economies where price stickiness arises due to the simultaneous presence of both menu and information costs we identify the relative importance of these costs using firm s survey data and analyze the response of prices and output following a permanent unexpected monetary shock for a given frequency of price adjustment we find that the information friction significantly amplifies the real effect of the shock when the shock is small or when it is not known by firms instead when the shock is large and known to firms the flexibility of prices increases and the real effects gradually vanish

on the taxation of durable goods this paper proposes a mirrleesian theory of commodity taxation in the presence of durable goods nondurable goods should be taxed uniformly provided that the preferences over nondurable consumption are weakly separable from labor effort a uniform taxation across all goods is optimal if the utility from durable consumption is linear and the preferences are additively separable between durable goods nondurable goods and labor effort if those conditions are not met wealth effects and substitution effects justify the use of differential commodity taxes to characterize the sign of the tax differential the paper exploits a substitution euler equation that links the marginal rate of substitution between durable and nondurable consumption across time finally an application of this theory suggests that housing investment should face higher tax rates than nondurable consumption

noncooperative bargaining models of marriage in this paper we discuss some simple noncooperative models of distribution within marriage in which the equilibria are not necessarily pareto optimal in which history and culture can affect which equilibrium is realized and in which distribution may depend on whether resources are controlled by the husband or by the wife recent moves away from single decision maker models of the family have permitted economists to address distribution within marriage and cooperative bargaining models have played the central role in these moves the next step is to permit strategic interaction between family members by modeling distribution within marriage as a noncooperative game noncooperative game theory allows great flexibility in specifying the rules of the game and unlike cooperative game theory imposes few a priori restrictions on the nature of equilibrium outcomes in particular noncooperative models neither assume nor imply that all equilibria are pareto optimal

how serious is the neglect of intrahousehold inequality in this report the authors develop a framework for assessing the consequences of ignoring intrahousehold inequality in the measurement and analysis of poverty and inequality they apply this framework to data for the philippines and conclude that 1 the result of neglecting intrahousehold inequality will probably be considerable understatement of the levels of poverty and inequality with the philippine data measured levels of inequality and poverty were off 30 percent as a result of ignoring intrahousehold variation and 2 patterns of inequality revealed by household level data are somewhat different from patterns revealed by individual level data but the differences seem not to be dramatic to confirm these results the exercise should be repeated with data from other countries

a news utility theory for inattention and delegation in portfolio choice recent evidence suggests that investors are inattentive to their portfolios and hire expensive portfolio managers this paper develops a life cycle portfolio choice model in which the investor experiences loss averse utility over news and can ignore his portfolio in such a model the investor prefers to ignore and not rebalance his portfolio most of the time because he dislikes bad news more than he likes good news such that expected news causes a first order decrease in utility consequently the investor has a first order willingness to pay a portfolio manager who rebalances actively on his behalf moreover the investor can diversify over time and his consumption aligns with predictions of mental accounting i structurally estimate the preference parameters by matching stock shares and stock market non participation over the life cycle my parameter estimates are in line with the literature generate reasonable intervals of inattention and simultaneously explain consumption and wealth accumulation over the life cycle here it matters that news utility preserves first order risk aversion even in the presence of stochastic labor income which also causes stock shares to rise in wealth

the liquid hand to mouth evidence from personal finance management software we use a very accurate panel of all individual spending income balances and credit limits from a personal finance software to document spending responses to the arrival of both regular and irregular income these payday responses are robust and homogeneous for all income and spending categories throughout the income distribution moreover we find that few people hold little or no liquidity we then analyze whether people hold liquidity cushions to cope with future liquidity constraints however we find that peoples responses are consistent with standard models without illiquid savings in which neither present nor future liquidity constraints are frequently binding received may 31 2016 editorial decision september 30 2017 by editor itay goldstein

small cues change savings choices we present evidence from randomized field experiments that 401 k savings choices are significantly affected by one to two sentence anchoring goal setting or savings threshold cues embedded in emails sent to employees about their 401 k plan even though these cues contain little to no marginal information cues that make high savings rates salient increased 401 k contribution rates by up to 2 9 of income in a pay period and cues that make low savings rates salient decreased 401 k contribution rates by up to 1 4 of income in a pay period cue effects persist between two months and a year after the email

women wages and discrimination some evidence from taiwan in 1982 male employees in taiwan earned an average monthly salary of nt 11 008 us 275 women earned under two thirds of this at nt 7 087 this paper examines whether the male female earnings differential in taiwan can be explained by different endowments between the sexes of productivity related characteristics such as education and work experience if men and women are paid according to the same wage structure different endowments will account for all the observed earnings differential any wage gap that remains as a residual after adjustment for endowments can be interpreted as evidence of wage discrimination between the sexes following the work of oaxaca and malkiel and malkiel there is now a large number of american studies that use human capital theory as the basis for decomposing sex specific earnings into an endowment component and a discrimination component estimates also exist for canada and britain 2 house in his calculations for cyprus has provided the first estimates for a developing country 3 a case study for taiwan is particularly interesting not only because of the role of female employment in taiwan s industrial growth but also because the quality of the data makes possible a sharper test of discrimination than most other studies

nutrition health birth order and seasonality intrahousehold allocation among children in rural india abstract nutrients available to children are determined largely by intrahousehold allocations there are a number of reasons why birth order may affect these allocations a model is developed to estimate critical parameters of parental preferences regarding the allocation of nutrients among their children latent variable estimates for rural south india indicate that parental preferences have productivity equity tradeoffs and parents favor older children the productivity equity tradeoff however is much less for the lean season therefore when food is scarcest parents follow more closely a pure investment strategy exposing their more vulnerable children to greater malnutrition tisk

durable consumption and asset management with transaction and observation costs this paper provides a contribution to the recent growing literature on rational inattention we start by testing the implications of recent rational inattention models of asset management liquidity holdings and savings using two novel datasets some predictions of these models are at odds with the data which motivates us to introduce a new model that shifts the focus from non durable to durable consumption and features both information and adjustment costs the focus on non durable consumption which departs from the previous literature is key to improve the fit of the model the investor s behavior in our setup combines elements of what the literature refers to as state dependent and time dependent adjustments the model allows us to quantify the information and transactions costs that are consistent with observed patterns of information review and asset trades a calibration of the model shows that very small information costs are sufficient to reproduce the relatively high frequency of observation that is found in the data we test a novel prediction of the model on the relationship between assets trades and durable goods trades and find it aligned with the data

gender and poverty issues and policies with special reference to asian developing countries abstract recent years saw the outpouring of a theoretical and empirical literature exploring the nexus between gender and poverty in developing countries this paper which provides a critical review of the literature examines the conceptual basis for a gender focused approach to poverty alleviation reviews the relevant empirical studies and data drawn principally but not exclusively from asian developing countries and explores the role of public policies to redress gender disparity the present review argues that the conceptual basis for many gender focused policies is far from well established the empirical foundations of many conventional wisdoms as well as of popular policies remain fragile due to the dearth of reliable gender segregated data and rigorous empirical studies the paper underscores the need for more careful empirical analyses as an input to formulating sound public policy with regard to gender and poverty

moving costs nondurable consumption and portfolio choice the substantial adjustment cost for housing affects nondurable consumption and portfolio allocations as well as the frequency of housing transactions a simple theoretical model roughly calibrated is used to assess the quantitative impact of adjustment costs on those decisions the impact on portfolios is found to be significant suggesting that housing wealth should be useful in empirical studies of portfolio choice the welfare loss from the transaction cost is also substantial the effect on nondurable consumption is small however so adjustment costs can explain only a small part of the equity premium puzzle

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

the risk premium and long run global imbalances this study proposes that heterogeneous household portfolio choices within a country and across countries offer an explanation for global imbalances we construct a stochastic growth multi country model in which heterogeneous agents face the following restrictions on asset trade first the degree of us equity market participation is higher than that of the rest of the world second a fraction of households in each country maintains a fixed share of equity in its portfolios in our calibrated model which matches the us net foreign asset position and the equity premium the average us household loads up more aggregate risk than the average foreign household by investing in risky assets abroad and issuing risk free assets as a result the us is compensated by a high risk premium and runs trade deficits even as a debtor country the long run average trade deficit in our model accounts for 50 of the observed us trade deficit

life cycle portfolio choice with liquid and illiquid financial assets abstract traditionally quantitative models that have studied households portfolio choices have focused exclusively on the different risk properties of alternative financial assets we introduce differences in liquidity across assets in the standard life cycle model of portfolio choice more precisely in our model stocks are subject to transaction costs as considered in recent macroliterature we show that when these costs are calibrated to match the observed infrequency of households trading the model is able to generate patterns of portfolio stock allocation over age and wealth that are constant or moderately increasing thus more in line with the existing empirical evidence

information learning and wage rates in low income rural areas in this essay we present evidence that employers in rural areas of developing countries have imperfect information with regard to the productivity of heterogeneous workers in addition to obtaining direct measures of the completeness of employer information we consider the implications of information asymmetries for the structure of casual labor markets we then evaluate the extent to which casual labor markets do in fact exhibit these attributes we find that 1 there is adverse selection out of the time rate labor market 2 employers discriminate statistically given two workers with different observed characteristics but the same actual productivity the worker from the group with the higher average productivity will have a higher wage 3 employers exhibit learning over time the extent of employer ignorance is negatively related to labor market exposure on the part of the workers and 4 calorie consumption affects productivity but is not rewarded in the time rate labor market in concluding we argue that an analysis of wage and employment patterns and the implications of these patterns for human capital investment in rural areas of developing countries that ignored the role of information problems could yield misleading conclusions

risk aversion wealth and background risk we use household survey data to construct a direct measure of absolute risk aversion based on the maximum price a consumer is willing to pay for a risky security we relate this measure to consumer s endowments and attributes and to measures of background risk and liquidity constraints we find that risk aversion is a decreasing function of the endowment thus rejecting cara preferences we estimate the elasticity of risk aversion to consumption at about 0 7 below the unitary value predicted by crra utility we also find that households attributes are of little help in predicting their degree of risk aversion which is characterized by massive unexplained heterogeneity we show that the consumer s environment affects risk aversion individuals who are more likely to face income uncertainty or to become liquidity constrained exhibit a higher degree of absolute risk aversion consistent with recent theories of attitudes toward risk in the presence of uninsurable risks jel d1 d8

heterogeneous consumers segmented asset markets and the real effects of monetary policy this paper proposes a novel mechanism by which changes in the distribution of money holdings have real effects specifically i develop a flexible price model of segmented asset markets that generates real aggregate effects of monetary policy through the dependence of optimal markups on the heterogeneity of money holdings because varieties of consumption bundles are purchased sequentially newly injected money disseminates slowly throughout the economy via second round effects the model predicts a short term inflation output trade off a liquidity effect countercyclical markups and procyclical wages after monetary shocks among other correlations of financial variables it also reproduces the empirical negative relationship between changes in the money supply and markups

optimal price setting with observation and menu costs we study the price setting problem of a firm in the presence of both observation and menu costs in this problem the firm optimally decides when to collect costly information on the adequacy of its price an activity which we refer to as a price review upon each review the firm chooses whether to adjust its price subject to a menu cost and when to conduct the next price review this behavior is consistent with recent survey evidence documenting that firms revise prices infrequently and that only a few price revisions yield a price adjustment the goal of the paper is to study how the firm s choices map into several observable statistics depending on the level and relative magnitude of the observation vs the menu cost the observable statistics are the frequency of price reviews the frequency of price adjustments the size distribution of price adjustments and the shape of the hazard rate of price adjustments we provide an analytical characterization of the firm s decisions and a mapping from the structural parameters to the observable statistics we compare these statistics with the ones obtained for the models with only one type of cost the predictions of the model can with suitable data be used to quantify the importance of the menu cost vs the information cost we also consider a version of the model where several price adjustment are allowed between observations a form of price plans or indexation we find that no indexation is optimal for small inflation rates

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

presidential address asset price dynamics with slow moving capital i describe asset price dynamics caused by the slow movement of investment capital to trading opportunities the pattern of price responses to supply or demand shocks typically involves a sharp reaction to the shock and a subsequent and more extended reversal the amplitude of the immediate price impact and the pattern of the subsequent recovery can reflect institutional impediments to immediate trade such as search costs for trading counterparties or time to raise capital by intermediaries i discuss special impediments to capital formation during the recent financial crisis that caused asset price distortions which subsided afterward after presenting examples of price reactions to supply shocks in normal market settings i offer a simple illustrative model of price dynamics associated with slow moving capital due to the presence of inattentive investors i address the implications for asset price dynamics of the apparent slow movement of investment capital to trading opportunities the arrival of new capital to an investment opportunity can be delayed by fractions of a second in some markets for example an electronic limit order book market for equities or by months in other markets such as that for catastrophe risk insurance accordingly prices respond to supply or demand shocks with a sharp reaction because of the relatively small subset of capital and thus risk bearing capacity that is immediately available to absorb a shock on short notice such a price impact is substantially reversed over time as additional capital becomes available the amplitude of the immediate price impact and the pattern of the subsequent recovery can reflect many sorts of attention costs to trade as well as institutional impediments to capital movement such as search costs for trading

sluggish responses of prices and inflation to monetary shocks in an inventory model of money demand we examine the responses of prices and inflation to monetary shocks in an inventory theoretic model of money demand we show that the price level responds sluggishly to an exogenous increase in the money stock because the dynamics of households money inventories leads to a partially offsetting endogenous reduction in velocity we also show that inflation responds sluggishly to an exogenous increase in the nominal interest rate because changes in monetary policy affect the real interest rate in a quantitative example we show that this nominal sluggishness is substantial and persistent if inventories in the model are calibrated to match u s households holdings of m2

on the measurement of poverty official statistics in the united states and the united kingdom show a rise in poverty between the 1970 s and the 1980 s but scepticism has been expressed with regard to these findings in particular the methods employed in the measurement of poverty have been the subject of criticism this paper re examines three basic issues in measuring poverty the choice of the poverty line the index of poverty and the relation between poverty and inequality one general theme running through the paper is that there is a diversity of judgments which enter the measurement of poverty and that it is necessary to recognize these explicitly in the procedures adopted there is likely to be disagreement about the choice of poverty line affecting both its level and its structure in this situation we may only be able to make comparisons and not to measure differences and the comparisons may lead only to a partial rather than a complete ordering the first section of the paper discusses the stochastic dominance conditions which allow such comparisons illustrating their application by reference to data for the united states the choice of poverty measure has been the subject of an extensive literature and a variety of measures have been proposed in the second section of the paper a different approach is suggested considering a class of measures satisfying certain general properties and seeking conditions under which all members of the class which includes many of those proposed give the same ranking those sceptical about measures of poverty often assert that poverty and inequality are being confounded the third section of the paper distinguishes four different viewpoints and relates them to theories of justice and views of social welfare

the intrahousehold demand for nutrients in rural south india individual estimates fixed effects and permanent income good estimates of nutrient intake responses to prices and income are very useful for the evaluation of the numerous efforts to improve nutrition in many developing countries through pricesubsidy and income generation policies we discuss three problems in standard estimates of these responses and then illustrate their implications for nutrient demand relations for a poor sample from rural south india 1 intra household nutrient allocations usually are ignored in this case nutrient intakes for females systematically have algebraically lower price elasticities than do those for males which may leave the females particularly vulnerable at times of food shortages 2 unobserved fixed effects may bias the estimates of responses to observed variables in this case not only the community fixed effects on which the previous literature has focused but also household and individual fixed effects are important failure to control for them results in substantial algebraically upward biases in many estimated price responses 3 most previous studies use current instead of permanent income which a priori may account for the low estimated income elasticities in this case however the use of permanent income does not change the conclusion that the nutrient intakes responses to income are quite small

wealth information acquisition and portfolio choice i solve with an approximation a grossman stiglitz economy under general preferences thus allowing for wealth effects because information generates increasing returns decreasing absolute risk aversion in conjunction with the availability of costly information is sufficient to explain why wealthier households invest a larger fraction of their wealth in risky assets one no longer needs to resort to decreasing relative risk aversion an empirically questionable assumption furthermore i show how to distinguish empirically between these two explanations finally i find that the availability of costly information exacerbates wealth inequalities copyright 2004 oxford university press

market opportunities genetic endowments and intrafamily resource distribution child survival in rural india the authors examine how intrafamily resource allocations respond to changes in economic conditions and to genetic differences in children by estimating the determinants of variations in the sex specific survival differentials of rural indian children based on standard census and household survey data they explore in particular the hypothesis that such differences are related to the relative returns to survival with households selectively allocating resources to children in response to variation in sex differences in their expected earnings opportunities as adults data are from the 1961 census and a 1971 household survey excerpt

portfolio rebalancing and asset pricing with heterogeneous inattention can households inattention to the stock market quantitatively account for the inertia in portfolio rebalancing i address this question by introducing an observation cost into a production economy with heterogeneous agents in this environment inattention changes endogenously over time and across agents i find that inattention explains the inertia in portfolio rebalancing and its heterogeneity across households inattention also rationalizes the limited stock market participation observed in the data and improves the asset pricing performance of the model finally i present a novel testable implication linking the effects of inattention on portfolio choices and asset prices to households funding liquidity

why are exchange rates so smooth a household finance explanation abstract empirical moments of asset prices and exchange rates imply that pricing kernels are almost perfectly correlated across countries otherwise observed real exchange rates would be too smooth for high sharpe ratios however the cross country correlation among macro fundamentals is weak we reconcile these facts in a two country stochastic growth model with heterogeneous households and a home bias in consumption in our model only a small fraction of households trade domestic and foreign equities we show that this mechanism can quantitatively account for the smoothness of exchange rates in the presence of volatile pricing kernels and weakly correlated macro fundamentals

consumption smoothing and portfolio rebalancing the effects of adjustment costs abstract a household s response to income and return shocks depends on the costs of portfolio adjustment in particular the extent of portfolio rebalancing and consumption smoothing are influenced by the presence of non convex portfolio adjustment costs suppose bonds can be adjusted costlessly while adjustments to stock accounts entail adjustment costs due to these portfolio adjustment costs the household demands both stocks and bonds a household can buffer some income fluctuations without incurring adjustment costs and engage in costly portfolio rebalancing less frequently using the estimated preference parameters and portfolio adjustment costs the response to income and return shocks is nonlinear and reflects the interaction of portfolio rebalancing and consumption smoothing

information aggregation in a noisy rational expectations economy abstract this paper analyzes a general equilibrium model of a competitive security market in which traders possess independent pieces of information about the return of a risky asset each trader conditions his estimate of the return both on his own private source of information and price which in equilibrium serves as a noisy aggregator of the total information observed by all traders a closed form characterization of the rational expectations equilibrium is presented a counter example to the existence of fully revealing equilibrium is developed
