resource based fdi and expropriation in developing economies abstract globally foreign direct investment fdi assets are expropriated more in resource extraction industries compared to other sectors despite the higher apparent risk of expropriation in resources countries more likely to expropriate also have a larger share of fdi in the resource sector an incomplete markets model of fdi is developed to account for this puzzle the type of government regime is stochastic with low penalty regimes facing a relatively low exogenous cost of expropriating fdi and country risk is measured by the variation in these costs across different regimes the key innovation of the model is that the government before the regime type is known is able to charge different prices to domestic and foreign investors for mineral rights granting cheap access increases fdi and reduces the country s share of resource rents increasing the temptation to expropriate in a relatively low penalty regime in very high risk countries subsidizing resource fdi increases the total value of output by raising investment and the net gains from expropriating in a low penalty regime outweigh the rents foregone under a high penalty one however a stochastic resource output price results in relatively low risk countries restricting fdi inflows to the resource sector instead windfall profits in this sector raise incentives to expropriate when prices are high yet minimization of the ex ante risk of expropriation is preferred owing to the relatively high penalty for expropriating these results imply a higher average share of resource based fdi in countries most likely to expropriate while resources account for a high share of expropriated assets compared to the sector s global share of fdi we show that the model is able to reconcile observed patterns of foreign investment and expropriation for a sample of 38 developing and emerging economies

from paper to plastic understanding the impact of ewic on wic recipient behavior abstract evidence shows that the special supplemental nutrition program for women infants and children wic is underutilized wic enrolls 52 7 of eligible persons and participants claim a fraction of available benefits researchers suggest that people underutilize wic because of the time needed to enroll in and use wic and because participants may believe that if others notice them participating in wic community members will stigmatize them recently enacted policies may reduce both time costs and potential for stigma associated with wic congress mandated that by 2020 all states disburse wic benefits through an electronic benefits transfer ewic system given that ewic reduces the time required for each transaction and and makes it more difficult to identify beneficiaries we expect wic redemptions to increase in addition ewic might also increase the chance wic recipients choose non wic foods for redemption increasing non wic expenditures to measure the impact of ewic on wic redemptions and non wic food expenditures we analyze data on grocery expenditures of 11 887 wic participating households in one state over the period it implemented ewic we find that after beneficiaries began redeeming wic benefits through ewic spending on non wic eligible foods did not change but redemptions of wic benefits increased

expropriation and direct investment abstract the paper considers a model in which private foreign investors make direct long lived capital investments in a small developing country that is subject to stochastic shocks to production depending upon the preferences of the host country we find that expropriation can occur because of either desperation or opportunism we show that under reasonable assumptions increased investment makes expropriation less likely to occur and that the level of investment chosen by atomistic foreign investors may be non optimal

optimal constrained interest rate rules we show that if policymakers compute the optimal unconstrained interest rate rule within a taylor type class they may be led to rules that generate indeterminacy and or instability under learning this problem is compounded by uncertainty about structural parameters since an optimal rule that is determinate and stable under learning for one calibration may be indeterminate or unstable under learning under a different calibration we advocate a procedure in which policymakers restrict attention to rules constrained to lie in the determinate learnable region for all plausible calibrations and that minimize the expected loss computed using structural parameter priors subject to this constraint

large investors regulatory taking and investor state dispute settlement abstract this paper offers an economic analysis of an international investor state dispute settlement regime isds in markets with large investors it identifies a reason for strategic overinvestment by the domestic industry leading to permissive regulation in the absence of isds an ideal investor state dispute settlement arrangement efficiency oriented transaction cost free with untouchable fully reliable and unbiased judges has positive and negative effects in this framework it generates an equal level playing field for domestic and foreign investors but it magnifies an existing overinvestment problem and may reduce world welfare the results explain anecdotal evidence according to which isds that protects foreign investors is liked by the domestic industry and disliked by other interest groups in the host country

can targeted transfers improve birth outcomes evidence from the introduction of the wic program abstract the goal of federal food and nutrition programs in the united states is to improve the nutritional well being and health of low income families a large body of literature evaluates the extent to which the supplemental program for women infants and children wic has accomplished this goal but most studies have been based on research designs that compare program participants to non participants if selection into these programs is non random then such comparisons will lead to biased estimates of the program s true effects in this study we use the rollout of the wic program across counties to estimate the impact of the program on infant health we find that the implementation of wic led to an increase in average birth weight and a decrease in the fraction of births that are classified as low birth weight we find no evidence that these estimates are driven by changes in fertility or selection into live births our preferred estimates suggest that wic initiation raised average birth weight by 2 g or by 7 g among infants born to mothers with low education levels these translate into estimated birth weight increases among participating mothers of approximately 18 to 29 g estimated treatments on the treated impacts among infants born to participating mothers with low education are of similar magnitude

private capital flows capital controls and default risk abstract what has been the effect of the shift in emerging market capital flows toward private sector borrowers are emerging market capital flows more efficient if not can controls on capital flows improve welfare this paper shows that the answers depend on the form of default risk when private loans are enforceable but there is the risk that the government will default on behalf of all residents private lending is inefficient and capital controls are potentially pareto improving however when private agents may individually default capital flow subsidies are potentially pareto improving

real implications of the zero bound on nominal interest rates if monetary policy succeeds in keeping average inflation very low nominal interest rates may occasionally be constrained by the zero lower bound the degree to which this constraint has real implications depends on the monetary policy feedback rule and the structure of price setting policy rules that make the price level stationary lead to small real distortions from the zero bound if policy imparts persistence into the inflation rate the real implications of the zero bound are large in the presence of backward looking price setting and small if prices are set to maximize profits

price level targeting vs inflation targeting a free lunch price level targeting without base drift and inflation targeting with base drift are compared under commitment and discretion with persistence in unemployment price level targeting is often said to imply more short run inflation variability and thereby more employment variability than inflation targeting counter to this conventional wisdom under discretion a price level target results in lower inflation variability than an inflation target if unemployment is at least moderately persistent a price level target also eliminates the inflation bias under discretion and as is well known reduces long term price variability society may be better off assigning a price level target to the central bank even if its preferences correspond to inflation targeting a price level target thus appears to have more advantages than commonly acknowledged

a theory of expropriation and deviations from perfect capital mobility there are many reasons why commodity trade fails to equate the rewards to factors of production in different countries consequently there is an incentive for factor movements between countries while movements of factors especially capital are important in the world economy they have not been sufficient to equate factor returns among countries the failure of capital flows to equate returns to capital is frequently attributed to political risks and left outside the sphere of economic analysis specifically investments abroad especially in ldc s are said to be more subject to the risk of expropriation or at least to unpredictable changes in the tax and exchange control regime adopted by the host country fears of foreign investors have often been realised williams i975 estimates that about 20 of the value of foreign investments carried into or made during i956 72 in ldc s was expropriated without compensation in this period in the past researchers in disciplines other than economics have been responsible for most of the analysis of expropriations we argue that an important set of economic considerations affect the nature of these impediments to capital mobility and this paper provides a theory of expropriation based on maximising behaviour by host countries and investors we use this theory to identify industry and national characteristics increasing the threat of expropriation and implying large deviations from equal returns on capital and to examine host country and home country policies minimising distortions from the threat of expropriation three broad conclusions follow from the analysis first the threat of expropriation can significantly distort the international allocation of capital even if the act of expropriation is relatively rare in the extreme acts of expropriation would never occur in a world of perfect foresight and rational decision making yet actions by investors to ensure that countries do not expropriate would be distorting second the ability of a country s government to expropriate foreign investments may actually reduce its welfare furthermore a host may be better off if home governments can retaliate against an expropriating country indeed an increase in the penalty imposed on an expropriating country may increase its welfare a government s power to expropriate after investments are made may alasdair smith and an associate editor made numerous valuable suggestions we would also like to thank g m grossman r w jones l a sjaastad n h stern and j e stiglitz for comments much of eaton s work on this paper was completed while he was a visitor at the graduate institute for international studies geneva an earlier version of this paper appeared under the same title as rpds

how important is precommitment for monetary policy we quantify the welfare differential between precommitment and discretionary monetary policy in three estimated models of the u s economy by calculating the permanent deviation of inflation from target that in welfare terms is equivalent to moving from discretion to precommitment using a range of reasonable central bank preference parameters this inflation equivalent ranges from 0 05 to 3 6 percentage points with a mid point of either 0 15 or 1 1 5 percentage points depending on the model in addition to the degree of forward looking behavior we show that the existence of transmission lags and or information lags is crucial for determining the welfare gain from precommitment

optimal horizons for inflation targeting abstract in this paper we investigate the problem of selecting an optimal horizon for inflation targeting in the united kingdom since there are two key ways of thinking about an optimal horizon we look at optimal horizons for both of these interpretations in addition to see whether our results are robust in the face of model uncertainty we compute optimal horizons for two different models with divergent structural and dynamic characteristics

does food retail access moderate the impact of fruit and vegetable incentives for snap participants evidence from western massachusetts abstract objectives this study investigates whether the response of supplemental nutrition assistance program snap participants to a 30 incentive on fruit and vegetable spending varies with their access to food retailers methods the analysis exploits the random assignment of snap households in hampden county ma to an intervention group that earned the incentive regression models for the impact of the incentive are augmented with measures of food retail access and interactions of random assignment status with food retail access the main outcome use of the snap benefit is based on electronic benefit transfer ebt card transaction records results although households that lived within a mile of a participating supermarket spent approximately 2 13 or 19 more per month on targeted fruits and vegetables at participating supermarkets than households that did not live within a mile of a participating supermarket we found no evidence that the impact of the incentive on snap fruit and vegetable spending varies with distance to retailers conclusions these findings imply that incentives to purchase fruits and vegetables were equally efficacious for snap households with high and low access to food retailers

habit formation in consumption and its implications for monetary policy models this paper explores a monetary policy model with habit formation for consumers in which consumers utility depends in part on current consumption relative to past consumption the empirical tests developed in the paper show that one can reject the hypothesis of no habit formation with tremendous condence largely because the habit formation model captures the gradual hump shaped response of real spending to various shocks the paper then embeds the habit consumption specication in a monetary policy model and nds that the responses of both spending and inflation to monetary policy actions are signicantly improved by this modication jel d12 e52 e43

solution and estimation of re macromodels with optimal policy macro models of monetary policy typically involve forward looking behavior except in rare circumstances we have to apply some numerical method to find the optimal policy and the rational expectations equilibrium this paper summarizes a few useful methods and shows how they can be combined with a kalman filter to estimate the deep model parameters with maximum likelihood simulations of a macro model with staggered price setting interest rate elastic output and optimal monetary policy illustrate the properties of this estimation approach

two sided expropriation and international equity contracts abstract the paper considers a model in which investors in two symmetrical countries can trade equity claims on their endowments the governments of the two countries expropriate the foreign owned securities if doing so raises domestic welfare in spite of the possibility of expropriation agents may still choose to hold completely pooled portfolios depending on preferences in the two countries increases in the level of domestic output can increase or decrease the probability of expropriation in the equilibria we consider agents hold too much foreign equity a reduction in foreign investment raises welfare by reducing the probability of expropriation

inflation forecast targeting implementing and monitoring inflation targets abstract inflation targeting is shown to imply inflation forecast targeting the central bank s inflation forecast becomes an explicit intermediate target inflation forecast targeting simplifies both implementation and monitoring of monetary policy the weight on output stabilization determines how quickly the inflation forecast is adjusted towards the inflation target money growth or exchange rate targeting is generally inferior than inflation targeting and leads to higher inflation variability commitment to target rules may be better than commitment to instrument rules

north south customs unions and international capital mobility the primary distinction in a north south trade accord is likely to be that the southern nation experiences more capital scarcity than its northern trade partner so the trade accord s impact on the southern trading partner s ability to attract capital may have welfare implications for both nations the authors extend the traditional analysis of customs unions to allow for international capital movements their results indicate that trade accords may affect the ability of southern nations to attract capital and may divert capital between southern nations moreover the welfare implications of north south trade accords may differ from those that predict the north american free trade agreement s nafta minor third country effects holding factor endowments constant the key implications of north south trade accords such as nafta are generally perceived to involve their impact on investment flows the authors try to understand the channels through which trade accords can affect north south investment flows a potential link between trade accords and investment flows may be how the accords affect the ability of the southern partner government to make commitments about the treatment of foreign investment they show that these accords can affect both the magnitude and pattern of inward foreign investment and production implying the possibility that both trade and financial diversion can stem from a bilateral regional trade accord novel effects that emerge under sovereign risk must be addressed when assessing the welfare implications of trade accords the greatest gains from integration are still achieved when integration takes place between the countries with the greatest potential gains from trade but the authors make a distinction these gains now include both current trade and inter temporal trade through foreign investment

optimal monetary policy in the euro area in the presence of heterogeneity abstract this paper examines the optimal design of monetary policy in the european monetary union in the presence of structural asymmetries across union member countries it derives analytically an optimal interest rate rule under commitment and studies the dependence of its coefficients on the parameters of the structural model of each economy the central bank s preferences for inflation and output stabilization as shown in its loss function and the relative size of each country based on a two country forward looking general equilibrium model which is estimated for two euro area countries germany and france we show that there are gains to be achieved by the ecb taking into account the heterogeneity of economic structures this finding appears to be robust under alternative weights given by the central bank to the stabilization of the target variables although the implementation of the proposed rule involves difficulties relating to data and estimation constraints as well as risks of accommodating structural divergences it is important that the ecb takes into consideration national characteristics in formulating its monetary policy especially in view of more countries joining the european monetary union in the future however as monetary and financial integration advances the welfare benefits of monetary policy responding to individual countries variables may become less significant

a small estimated euro area model with rational expectations and nominal rigidities abstract we estimate a small model of the euro area to be used for evaluating alternative monetary policy strategies starting with the relationship between output and inflation we compare the fit of the nominal wage contracting model due to taylor j political econom 88 1980 1 and the relative real wage contracting model proposed by buiter and jewitt the manchester school 49 1981 211 reprinted in buiter ed macroeconomic theory and stabilization policy manchester university press manchester 1989 and estimated with u s data by fuhrer and moore quart j econom 110 1995 127 while fuhrer and moore reject nominal contracts in favor of relative contracts which induce more inflation persistence we find that both specifications fit euro area data reasonably well when considering france germany and italy separately however we find that nominal contracts fit german data better while the relative contracting model does well with respect to formerly high inflation countries such as france and italy we close the model by estimating an aggregate demand relationship and investigate the implications of nominal versus relative contracts for the inflation output variability tradeoff when monetary policy follows taylor s rule

learning in a misspecified multivariate self referential linear stochastic model this paper introduces a general method to study stability under learning of equilibria resulting from agents with misspeci ed perceptions of the law of motion of the economy this is done by transforming the actual and perceived laws of motion into the form of seemingly unrelated regressions and then linearly projecting the actual law of motion into the same class as the perceived law of motion i study the new keynesian is lm model with inertia under all possible classes of restricted perceptions it turns out that the results found in bullard and mitra 2002 2003 are robust under misspeci ed expectations

maintaining price stability how long is the medium term using a small estimated forward looking model of the euro area economy this paper analyses the determinants of the optimal monetary policy horizon for maintaining price stability first the optimal policy horizon for a price level objective is generally longer than that for an inflation objective second the policy horizon becomes longer the greater the weight on other objectives like minimising output gap and interest rate variability third the optimal policy horizon is shorter the higher the degree of forward lookingness in the economy and the greater the slope of the phillips curve finally even if society cares only about inflation stabilisation it often pays to give the central bank a price level objective provided the horizon is optimally chosen to be somewhat longer

optimal monetary policy and the role of hybrid inflation price level targets this study investigates the role of hybrid inflation price level targets as a solution to the well known stabilization bias problem that arises under discretionary policies the analysis shows that social welfare will be improved by employing a weighted average of inflation and price level as one of the central bank s target variables in addition to the output gap growth target the reason is that imposing the optimal hybrid target will reduce inflation variability in a highly efficient way in particular the optimal hybrid regime outperforms other previously suggested regimes when the degree of inflation persistence is moderate

inflation risk premia in the term structure of interest rates this paper estimates the size and dynamics of inflation risk premia in the euro area based on a joint model of macroeconomic and term structure dynamics information from both nominal and index linked yields is used in the empirical analysis our results indicate that the inflation risk premium on euro area 10 year nominal yields was approximately equal to 20 basis points on average over the 1999 2007 period the inflation premium has also been subject to moderate but statistically significant fluctuations for the post 2003 period in which reliable index linked bond prices are available our results suggest that increases in the raw break even inflation rate above 2 the upper bound of the european central bank s definition for price stability have mostly reflected variations in the inflation risk premium while long term inflation expectations have remained well anchored

an optimizing is lm specification for monetary policy and business cycle analysis we ask whether relations of the is lm type can sensibly be used for the aggregate demand portion of a dynamic optimizing general equilibrium model intended for analysis of issues regarding monetary policy and cyclical fluctuations the main result is that only one change the addition of a term regarding expected future income is needed to make the is function match a fully optimizing model whereas no changes are needed for the lm function this modification leads to a dynamic forward looking model of aggregate demand that is tractable and usable with a wide variety of aggregate supply specifications theoretical applications concerning price level determinacy and gradual price adjustment are included

long run impacts of childhood access to the safety net a growing economics literature establishes a causal link between in utero shocks and health and human capital in adulthood most studies rely on extreme negative shocks such as famine and pandemics we are the first to examine the impact of a positive and policy driven change in economic resources available in utero and during childhood in particular we focus on the introduction of a key element of the u s safety net the food stamp program which was rolled out across counties in the u s between 1961 and 1975 we use the panel study of income dynamics to assemble unique data linking family background and county of residence in early childhood to adult health and economic outcomes the identification comes from variation across counties and over birth cohorts in availability of the food stamp program our findings indicate that the food stamp program has effects decades after initial exposure specifically access to food stamps in childhood leads to a significant reduction in the incidence of metabolic syndrome obesity high blood pressure and diabetes and for women an increase in economic self sufficiency overall our results suggest substantial internal and external benefits of the safety net that have not previously been quantified

the economics and nutritional impacts of food assistance policies and programs recent evidence on malnutrition and poverty raise important questions on the role of food assistance policies and programs in this review article we examine evidence on the economic and nutritional impacts of international food assistance programs faps and policies the returns on investments in faps are on average high but depend considerably on the targeting and cost structures as well as on food quality and role of complementary activities we disaggregate findings into four classes of recipients returns to faps are highest for children under two but faps oriented towards early childhood interventions are less well funded than are interventions aimed at school age children or at the broader largely adult population even though available evidence indicates that these latter classes of interventions offer considerably lower average returns in economic health and nutrition terms nonetheless fap effectiveness in achieving any of several objectives varies with a range of key factors including targeting additionality seasonality timeliness incentive effects social acceptability and political economy considerations

institutions and the external capital structure of countries abstract a widespread view holds that countries that finance themselves through foreign direct investment and portfolio equity rather than bonds and loans are less prone to crises but what determines countries external capital structures in a cross section of advanced economies emerging markets and developing countries we find that equity like liabilities as a share of countries total external liabilities are positively and significantly associated with indicators of educational attainment openness natural resource abundance and especially institutional quality these relationships are robust to attempts to control for possible endogeneity suggesting that better institutional quality may help improve countries external capital structures

taxation and the transfer of technology by multinational firms this paper analyzes a multinational s transfer of technology to a foreign subsidiary for the case where there is a risk of expropriation an expropriation is assumed to give rise to competition between the parts of the previous multinational enterprise to reduce the benefit of expropriation the multinational generally transfers an inferior technology even if the transfer of technology is costless with a reduced benefit of expropriation the multinational has to pay lower taxes to prevent expropriation the multinational optimally transfers additional technology over time if it has a finite horizon in the country for this case tax payments also are shown to increase over time in a tax holiday like fashion

wic in your neighborhood new evidence on the impacts of geographic access to clinics a large body of evidence indicates that conditions in utero and health at birth matter for individuals long run outcomes suggesting potential value in programs aimed at pregnant women and young children this paper uses a novel identification strategy and data from birth and administrative records over 2005 2009 to provide causal estimates of the effects of geographic access to the special supplemental nutrition program for women infants and children wic my empirical approach uses within zip code variation in wic clinic presence together with maternal fixed effects and accounts for the potential endogeneity of mobility gestational age bias and measurement error in gestation i find that access to wic increases food benefit take up pregnancy weight gain birth weight and the probability of breastfeeding initiation at the time of hospital discharge the estimated effects are strongest for mothers with a high school education or less who are most likely eligible for wic services

robust monetary policy with imperfect knowledge we examine the performance and robustness properties of monetary policy rules in an estimated macroeconomic model in which the economy undergoes structural change and where private agents and the central bank possess imperfect knowledge about the true structure of the economy private agents rely on an adaptive learning technology to form expectations and update their beliefs based on incoming data policymakers follow an interest rate rule aiming to maintain price stability and to minimize uctuations of unemployment around its natural rate but are uncertain about the economy s natural rates of interest and unemployment we show that in this environment the scope for economic stabilization is signiflcantly reduced relative to an economy under rational expectations with perfect knowledge furthermore policies that would be optimal under perfect knowledge can perform very poorly when knowledge is imperfect e cient policies that take account of private learning and misperceptions of natural rates call for more aggressive responses to in ation that would be optimal under perfect knowledge we show that such policies not only improve performance in our baseline model but are also quite robust to potential misspeciflcation of private sector learning and the magnitude of variation in natural rates

international lending with moral hazard and risk of repudiation in this paper i examine the constrained optimal pattern of capital flows between a lender and a borrower in an environment in which there are two impediments to forming contracts the first impediment to contracting arises from the assumption that lenders cannot observe whether borrowers invest or consume borrowed funds this assumption leads to a moral hazard problem in investment the second impediment arises from the assumption that the borrower as a sovereign nation may choose to repudiate his debts the optimal contract is shown to specify that the borrowing country experience a capital outflow when the worst realizations of national output occur this seemingly perverse capital outflow forms a necessary part of the optimal solution to the moral hazard problem in investment
