country portfolios under global imbalances abstract this paper studies the composition of country portfolios under global imbalances when countries are identical the optimal portfolio is fully diversified which reflects the cross country symmetric self hedging lucas 1982 assuming a structural country asymmetry in patience we construct a model of portfolio choices that features persistent non zero net foreign assets nfa because the latter opens a gap between gnp and gdp we found that an asymmetric hedging of net portfolio returns emerges in addition to the otherwise only lucas symmetric self hedging in shaping the gross country portfolios which implies a short long position of the local asset in the debtor creditor country the resulting portfolio is home biased we calibrate our model to the u s and china data over 1999 2017 and show that it matches the portfolio data for countries with unbalanced net external positions well

meta analysis in model implementation choice sets and the valuation of air quality improvements this research illustrates how the methods developed for meta analysis can serve to document and summarize voluminous information derived from repeated sensitivity analyses our application is to the sensitivity of welfare estimates derived from discrete choice models to assumptions about the choice set these assumptions affect welfare estimates through both the estimated parameters of the model and conditional on the parameters the substitution among alternatives in our specific application the evaluation is in terms of estimated benefits of air quality improvements in los angeles based on discrete choices of neighborhood and housing copyright 2007 john wiley sons ltd

a utility consistent combined discrete choice and count data model assessing recreational use losses due to natural resource damage abstract a two stage budgeting approach can often be taken when analyzing consumer choice situations in this paper we examine the particular situation where a consumer makes purchases of a discrete commodity of which there are a number of brands in the first stage the consumer decides how many purchases to make in the second stage the consumer decides how to allocate these purchases across brands our econometric approach to this type of situation uses a utility consistent combined discrete choice and count data model the second stage which is specified as a multinomial choice model produces a price index for the commodity which is used to estimate the first stage which is specified as a count data model we apply the model to recreational demand behavior in alaska in order to estimate the welfare losses suffered by recreational users due to the exxon valdez oil spill these results may provide useful input to government agencies attempting to estimate the appropriate level of taxes fines or regulations for deterring damage to the environment

the performance of nested logit models when welfare estimation is the goal in this paper we examine the performance of nested logit models in the face of two specification errors the first specification error arises when a nested logit model is appropriate but the wrong nesting structure is chosen the second specification error occurs when the underlying stochastic process is not consistent with nested logit particular attention is placed upon the impact that these errors can have on welfare predictions monte carlo experiments are used together with analytical results to examine the resulting bias to welfare estimates in addition we explore the value of alternative model selection criteria in choosing nesting structures

current account imbalances and financial integration in the euro area abstract while the current account of the euro area as a whole has remained almost balanced in the past two decades several member countries have sizeable deficits or surpluses in this paper we interpret these imbalances as indicators of net capital flows among the euro area countries we distinguish between balances against the euro zone and the rest of the world and examine these for the eu 15 countries we find that for euro members the net flows follow differences in per capita incomes even before the introduction of the euro our results show further that with the introduction of the common currency the elasticity with respect to per capita incomes of net capital flows within the euro area has increased for the members of the euro zone this increase can neither be observed for the flows between the euro members and the rest of the world nor for the flows between the countries that stayed outside the monetary union and the euro zone we interpret this as evidence for increasing financial integration in the euro area there is also some evidence suggesting that the introduction of the euro has led to some financial diversion

a repeated nested logit model of atlantic salmon fishing participation and site choice for atlantic salmon fishing are modeled in the context of a repeated three level nested logit model consumer s surplus measures are derived for different levels of species availability in the penobscot river the most important salmon river in new england for comparison six other travel cost models are estimated these include restrictive cases of the nested logit model a partial demand model and two single site demand models comparisons across these models indicate the importance of modeling the participation decision including income effects and of adopting a nested logit structure rather than a single level logit structure

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

exchange rate variability and asset trade in popular discussion about the merits of different international monetary arrangements it is often maintained that increased exchange rate variability has a negative influence on international tra

an exploration in the theory of exchange rate regimes three exchange rate regimes a float a one sided peg and a cooperative peg are evaluated and compared in terms of efficiency and welfare levels the framework of analysis embodies country specific monies with the money of each country being used to transact in its commodity markets and its currency denominated bonds welfare levels depend only on consumption levels in the presence of perfect foresight all equilibrium allocations are pareto efficient in a floating exchange rate regime the perfect foresight equilibrium allocation coincides with an equilibrium of a costless barter economy the same result holds in a one sided peg if the pegging country s exchange rate stabilizing authority breaks even over time in a cooperative peg regime there is a different equilibrium allocation for each combination of exchange rate levels and monetary policies problems of policy coordination and conflicts in desired monetary policies are discussed

a cautionary note in using patterns of shocks to determine optimal exchange rate policy an exploration of nepalese and indian exchange rate relations 1964 1994 nepal and india are developing countries in asia whose hard peg has existed for almost forty years as well as no restriction on capital mobility between both countries however empirical results suggest that nepal and india do not face symmetric patterns of shocks and are thus not suitable for a fixed exchange rate under this criteria one possible explanation may be that the monetary authority plays some role in the short run to reduce the cost of the exchange rate regime this suggests that some caution should be used in basing optimal exchange rate policy on this single criteria

foreign currency debt risk premia and macroeconomic volatility abstract this paper studies the relationships between foreign currency debt macroeconomic volatility and risk premia in a model of a small open emerging market economy the external value of the local currency is counter cyclical so that foreign currency debt requires larger repayments than local currency debt in bad states of nature the level of foreign currency denominated debts therefore affects the volatility of aggregate demand and by extension of the exchange rate exchange rate volatility is in turn an important determinant of the risk premium on local currency debt finally this risk premium is a major factor in the choice of local versus foreign currency for emerging market borrowers the mutual endogeneity of foreign currency debt risk premia and macroeconomic volatility creates important feedback effects in the economy small increases in international risk aversion may entail large amplification effects on macroeconomic volatility since domestic borrowers substitute towards cheaper but riskier foreign currency debt finance

macro economic shocks the erm and tri polarity the authors use the comparative behavior of real output growth and inflation behavior of members and nonmembers of the exchange rate mechanism erm to analyze the importance of erm membership on macroeconomic performance an econometric procedure for identifying temporary and permanent shocks to output is proposed and executed the results confirm that the erm has acted as a vehicle for macropolicy coordination between members the authors also investigate several issues relating to the hypothesis of global economic tri polarity between the united states germany and japan copyright 1995 by mit press

annual fees and recreation choice models of recreation behavior have typically ignored the role of fixed annual fees such as the fee for a recreational license in determining choice and welfare we demonstrate how techniques from the literature on discrete continuous choice and two part tariffs can address a situation where fixed annual fees are essential to determining the choice of a recreation site we explore how accounting for value captured by fixed fees can influence the way resource changes are assessed

the slope of the yield curve and real economic activity tracing the transmission mechanism abstract the slope of the yield curve in the us and the uk is strongly associated with the temporary rather than the permanent components of real economic activity suggesting that the yield curve affects economic activity primarily through the demand side

consumption baskets and currency choice in international borrowing abstract we propose a novel explanation for the empirically low prevalence of external borrowing in local currency in emerging market economies a phenomenon sometimes referred to as the original sin of international finance we study the endogenous currency denomination of an emerging economy s assets and liabilities within the context of a dynamic stochastic general equilibrium dsge model with portfolio choice featuring non tradable goods and nominal rigidities we find that these features lower the correlation between the local currency and domestic lenders consumption they thus reduce the risk premium demanded by domestic lenders on local currency debt and can therefore help explain the low willingness of foreigners to lend in local currency

financial integration and the wealth effect of exchange rate fluctuations abstract recent years have witnessed a large increase in international financial integration in the form of largely offsetting cross holdings across countries we assess how such financial leverage affects the international transmission of monetary shocks and find that it leads to sizable welfare differentials that far exceed the impact due to nominal rigidities we document the relevance of the exact nature of holdings with bond holdings associated with larger effects than equity holdings the impact of financial leverage on welfare is also sensitive to the extent of exchange rate pass through and the substitutability between goods produced in different countries

money bonds and foreign exchange in the theory of finance capital markets provide securities which allow the ownership of productive assets to be allocated among investors according to their willingness to bear risk in exchange for return and independently of their tastes for the productive services provided by the assets this paper uses the theory of finance to study the role of money as a productive asset and the transformation of money into a portfolio asset true to its purpose the capital market provides securities nominal bonds that allow an allocation of the current services of the money supply according to its current productivity and without regard for its future purchasing power risk and an allocation of the future purchasing power risk of the money supply according to the willingness of investors to bear this risk in exchange for return and without regard for investor needs for the future transactions services of money in open

real exchange rates under alternative nominal exchange rate systems abstract the paper develops an equilibrium model of the determination of exchange rates the relative price of nontraded goods and the current account the focus is on the effects of various real and nominal disturbances and the conditions under which the nominal exchange rate system is neutral with respect to real variables in the economy the model demonstrates an assymetry in the roles of trade and nontraded goods in affecting exchange rates an econometric investigation of the raltion between the exchange rate system and the variability of real exchange rates provides some evidence against the neutrality hypothesis

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

two stage estimation to control for unobservables in a recreation demand model with unvisited sites the role of unobserved site attributes is a growing concern in recreation demand modeling one solution in random utility models rums involves separating estimation into two stages where the rum is estimated with alternative specific constants ascs in the first stage and the estimated ascs are regressed on the observed site attributes in the second stage prior work estimates the second stage with ordinary least squares ols and two stage least squares regression we present an application with censored regression in the second stage we show ols produces inconsistent parameters when there are unvisited sites with no estimable ascs and that censored regression avoids this problem

exchange intervention policy in a multiple country world abstract intervention policy is examined in a three country model employment and output in each country depend upon the domestic currency value of a natural basket of currencies called the sally each country will find it desirable to intervene to stabilize its sally rate if capital movements are more volatile than trade flows this is a natural generalization of well known small country results however in this general equilibrium setting it is clear that such a policy can destabilize employment in another country and lead to retaliation currency unions are also examined and found to have similar spillover problems

the cyclical properties of disaggregated capital flows abstract we analyze the second moment properties of the components of international capital flows and their relationship to business cycle variables output investment and the real interest rate in 22 industrial and emerging countries total inward flows are procyclical with respect to all three macro variables net outward flows are countercyclical with respect to output and investment in most industrial and emerging countries disaggregated inward flows positively comove with output in industrial countries and with investment and the real interest rate in the g7 economies inward foreign direct investment is the only non procyclical type of inward capital flows with respect to output in the developing economies formal statistical tests based on nonparametric bootstrap techniques detect significant variance increases in all g7 countries disaggregated capital flows over exogenous and endogenously estimated breaks

international portfolios a comparison of solution methods we compare the performance of the perturbation based local portfolio solution method of devereux sutherland 2010a 2011 with a global solution method as a test suite we use model specifications that broadly capture features of international financial trade between advanced economies and between advanced and emerging economies we consider both symmetric country setups and asymmetric setups that capture important empirical facts such as differences in macroeconomic volatility differences in portfolio composition and high equity premia we find that the local method performs well at business cycle frequencies both in the symmetric and asymmetric settings while significant differences arise at long horizons in asymmetric settings

choice set formation for outdoor destinations the role of motivations and preference discrimination in site selection for the management of public expenditures on protected areas effective public expenditure currently dominates the management focus of many protected areas this calls for explicit modeling of constraints and motivations that respectively obstruct and stimulate visits to selected outdoor destinations choice set formation is the result of screening and or inclusion of specific sites alternatives to form the set of sites considered in real choices evidence shows that the omission of a structural representation of choice set formation is harmful to econometric inference yet the literature has largely ignored the underlying behavioral phenomenon we show using a discrete choice experiment involving selection among seven recreational sites in an italian national park that choice set formation is behaviorally relevant even after controlling for preference discrimination motivations why visit are important determinants of preliminary site screening for choice set inclusion as well as site selection justifying the additional value of such modeling extension

financial development international capital flows and aggregate output abstract we develop a tractable two country overlapping generations model and show that cross country differences in financial development can explain three recent empirical patterns of international capital flows financial capital flows from relatively poor to relatively rich countries while foreign direct investment flows in the opposite direction net capital flows go from poor to rich countries despite its negative net international investment positions the united states receives a positive net investment income international capital mobility affects output in each country directly through the size of domestic investment and indirectly through the aggregate saving rate under certain conditions the indirect effect may dominate the direct effect so that international capital mobility raises output in the poor country and globally although net capital flows are in the direction to the rich country we also explore the welfare and distributional effects of international capital flows and show that the patterns of capital flows may reverse along the convergence process of a developing country our model adds to the understanding of the costs and the benefits of international capital mobility in the presence of domestic financial frictions

decomposing the structural identification of non market values abstract this paper addresses the issue of transparency in structural modeling by investigating how the assumptions of a structural model contribute to its identification of non market values assumptions about the form of the utility function the depiction of preference heterogeneity and the definition for the choice set are shown to jointly identify a partition of preference space which explains observed behavior the borders of the partition reflect substitution patterns the regions in the partition set identify preferences assumptions about the distribution of preferences within each region point identify partial equilibrium welfare measures together these observations provide a framework for decomposing the structural identification of non market values the new framework allows analysts to explain how their modeling assumptions influence estimates for benefits and costs this addresses federal guidelines for quantifying uncertainty in the modeling assumptions which enter benefit cost analysis the framework is demonstrated by decomposing estimates of the mwtp for air quality

international capital flows portfolio composition and the stability of external imbalances abstract this paper develops a simple and tractable model of net capital flows in which time varying gross country portfolios are an essential element in current account imbalances the main constituents of country portfolios in the model are general derivatives which could be interpreted as nominal bond assets and liabilities in particular under very weak conditions the world wealth distribution is stationary stationarity is generated by movements in derivative i e bond risk premia such that the return on a debtor country s gross liabilities is less than the return on its gross assets this is well known feature of the us international investment position we also provide suggestive evidence that a similar property holds more widely for a sample of advanced and emerging market countries

an efficiency approach to choice set formation theory and application to recreational destination choice an unresolved debate in behavioural choice research surrounds specifying individual choice sets to overcome the limitations of deterministic and probabilistic approaches in a framework consistent with individual optimizing behaviour this study develops an efficient frontiers approach to the choice set problem in the context of revealed preference destination choice stochastic frontier models relating costly inputs to utility generating outputs are estimated to measure the efficiency of sites choice sets are then formed by retaining sites that exceed alternative efficiency thresholds choice set composition site choice efficiency and probability of selection and consumer surplus are evaluated in the case of fishery site choice in maine

trade in nominal assets and net international capital flows abstract nominal assets play a major role in international financial markets while trade in indexed bonds is limited as a result agents are exposed to both price and exchange rate uncertainty nonetheless previous research on net capital flows has assumed the presence of a risk free vehicle to intertemporal asset trade in this paper we develop a general equilibrium intertemporal model with trade limited to nominal bonds and equity we find that exposure to nominal risk dampens net capital flows thus making economies effectively more closed

foreign direct investment and debt financing in emerging economies the rich dynamics of capital flows is an important characteristic of business cycles in emerging market economies in the data external debt is always procyclical while fdi is procyclical only in normal times we provide a microfounded rationale for this pattern by linking financial shocks to capital flows for this purpose we build a small open economy model in which firms are subject to borrowing constraints and are either owned domestically or by foreign investors who purchase firms through fdi during a financial crisis the valuation gap per unit net worth between foreign and domestic investors widens which triggers more fdi inflow our model produces business cycle moments consistent with empirical observations

policy convergence the exchange rate mechanism and the misalignment of exchange rates some tests of purchasing power parity and generalized purchasing power parity the paper focuses on the convergence issues and the long run credibility of the european monetary system ems and more specifically on the evaluation of the effectiveness of the exchange rate mechanism erm in generating a stabilizing effect on real exchange rates across member countries for this purpose we execute some tests of long run purchasing power parity ppp for an erm group and a non erm group of countries using both the engle and granger procedure and the more powerful johansen cointegration technique we also execute a test of generalized ppp exploiting an idea developed by enders and hurn testing for ppp in a multicountry setting may be a useful methodology to identify the optimal currency area suggested by the data generation process on the basis of the reported homogeneity of real exchange rate behaviour of the countries considered

a portfolio model of capital flows to emerging markets since the crises of the late 1990 s most emerging market economies have built up substantial positive holdings of us dollar treasury bills while at the same time experiencing a boom in fdi capital inflows this paper develops a dsge model of the interaction between an emerging market economy and an advanced economy which incorporates two way capital flows between the economies the novel aspect of the paper is to make use of new methods for analyzing portfolio choice in dsge models we compare a range of alternative financial market structures in each case computing equilibrium portfolios we find that an asymmetric configuration where the emerging economy holds nominal bonds and issues claims on capital fdi can achieve a considerable degree of international risk sharing this risk sharing can be enhanced by a more stable monetary policy in the advanced economy

trade and insurance with moral hazard abstract previous literature on the use of trade policy for insurance has relied implicitly on moral hazard and adverse selection as the reasons for the failure of private markets for risk bearing this paper begins with the observation that such forces should be incorporated explicitly into the models to ensure a fair comparison between markets and governments for the case of moral hazard it is found that market equilibrium given exclusive insurance is an informationally constrained pareto optimum in one case of non exclusive insurance a systematic role for government insurance is found but the scope of trade policy is ambiguous

financial globalization and monetary policy abstract recent data show substantial increases in the size of gross external asset and liability positions the implications of these developments for optimal conduct of monetary policy are analyzed in a standard open economy model which is augmented to allow for endogenous portfolio choice the model shows that monetary policy takes on new importance due to its impact on nominal asset returns nevertheless the case for price stability as an optimal monetary rule remains in fact it is reinforced even without nominal price rigidities price stability is optimal because it enhances the risk sharing properties of nominal bonds

the effect of consumers real world choice sets on inferences from stated preference surveys for stated preference sp studies we develop a model that assesses the influence of choice set misspecification arising from the omission of perceived substitutes among real world alternatives in the same class of goods this problem is most likely to be present when individuals are allowed to select a no purchase option instead of being forced to choose from an explicit set of sp alternatives with hypothetical attribute levels a convenient feature of our model is that researchers do not need to know exactly which omitted real substitute the individual most prefers only the set of real substitutes that exists in our empirical illustration a comparison of rival models suggests researchers who overlook the presence of perceived real alternatives related to an sp experiment can end up with noticeably biased welfare estimates our more general model suggests that it may be prudent for future sp researchers to anticipate then test and possibly correct for distortions in utility parameter estimates that result from this problem

latent consideration sets and continuous demand systems this paper develops a theoretically consistent continuous demand system model that incorporates latent probabilistic consideration sets in contrast to existing discrete choice consideration models the proposed model is econometrically tractable with consumption data for many goods the model s empirical properties are illustrated with an 89 site recreation data set from the 1994 national survey of recreation and the environment nsre parameter and welfare estimates suggest that the latent consideration set models fit the data better and may imply a bias variance tradeoff relative to traditional models

international macroeconomic fluctuations and the current account intertemporal models of the current account generally assume that global shocks do not affect the current account we use this assumption to identify global and country specific shocks in a bivariate var we test the quality of the identification using evidence from g7 data in accordance with the theory we observe a link between the global shock and a measure of the world real interest rate we also find that long term output growth is driven by global factors in most countries that country specific shocks are less persistent in smaller economies and generally less volatile than global shocks

on the denomination of government debt a critique of the portfolio balance approach abstract we show that some classes of sterilized interventions have no effect on equilibrium prices and quantities the proof does not require complete markets ricardian equivalence monetary neutrality or the law of one price moreover regressions of exchange rates or interest differentials on variables measuring debt s currency composition contain no information about the affectiveness of such interventions other interventions require changes in monetary and fiscal policy their effects depend generally on the influence of these changes on the economy and not on the intervention alone in short sterilized intervention is not as the portfolio balance approach indicates an extra policy instrument

the role of saving and investment in exchange rate determination under alternative monetary mechanisms abstract we argue that the demand for national currencies depends on existing payment arrangements for imports and exports therefore exchange rate movements depend on these arrangement as a result the relationship between exchange rate movements and various macroeconomic aggregates like saving and investment depend on what we call the monetary mechanism these points are explicitly demonstrated by studying two extreme monetary mechanisms one in which all payments are done with the seller s currency and one in which all payments are done with the buyer s currency

accounting for choice set endogeneity in random utility models of recreation demand abstract modeling the choice among a discrete set of recreation alternatives is driven by the possible patterns of substitution among sites researchers typically assume that the individual s choice set is the same as the set of alternatives included in the recreation survey instrument our endogenous choice set model is a generalization of the standard multinomial logit random utility model which allows for the possibility of heterogeneous choice sets that are endogenously determined in the model using two examples we show that parameter and compensating variation estimates differ greatly between the endogenous choice set model and the traditional logit model

the external wealth of nations measures of foreign assets and liabilities for industrial and developing countries abstract although capital flows are closely monitored surprisingly little is known about the accumulated stocks of foreign assets and liabilities held by various countries especially in the developing world this paper constructs estimates of foreign assets and liabilities and their equity and debt subcomponents for a sample of 67 industrial and developing countries it characterizes the stylized facts of international balance sheets and asks whether there are trends in net foreign asset positions and shifts in debt equity ratios over time finally it explores the sensitivity of estimated stock positions to the treatment of valuation effects not captured in balance of payments data

real transfers in fixed exchange rate systems and the international adjustment mechanism abstract fixed exchange rates can be maintained by different types of stabilization schemes this paper takes a look at some alternative institutional settings and shows that there is an inherent redistribution mechanism in some of them that will influence the world allocation of consumption an examination of the global adjustment to monetary disturbances illustrates some interesting implications of the institutional differences between alternative systems the results suggest that the description of the international adjustment mechanism under fixed exchange rates given by the monetary approach to the balance of payments is valid only under quite restrictive assumptions

valuation effects with transitory and trend productivity shocks abstract changes in asset prices of a country s foreign assets and liabilities valuation effects are commonly thought of as stabilizing they counteract current account movements and mitigate the impact of the current account on the country s net foreign asset nfa position this paper shows that whether valuation effects are stabilizing or not depends critically on the nature of the underlying productivity shocks in response to transitory shocks valuation effects are stabilizing but in response to trend shocks such effects amplify the impact of the current account on nfa position these contrasting effects arise because optimally smoothing consumers respond differently to a transitory shock than to a trend shock to income this theoretical result finds empirical support with g7 countries data and is illustrated by the pattern of external imbalances between the u s and other g7 countries since the 1990s

trade in nominal assets monetary policy and price level and exchange rate risk in a previous paper trade in risky assets i have analyzed the pattern of international trade in risky real assets between barter economies relying on the law of comparative advantage and using autarky asset price differences to predict the pattern of asset trade in this paper the analysis is extended to international trade in nominal assets assets with returns paid in currencies between monetary economies the risk chracteristics of real returns on nominal assets depend on price level and exchange rate risk and therefore on monetary policy it is examined how different combinations of monetary policies and exchange rate regimes affect nominal assets return risk characteristics their autarky perices and hence their trade pattern when countries differ with respect to their outputs or their attitudes towards risk when world asset markets are incomplete different monetary policies and exchange rate regimes have dramatic effects on risk characteristics of home and foreign currency bonds and on the trade pattern in these assets as well as on aggregate capital and current accounts

an empirical analysis of real exchange rate movements in the euro this study uses a long run structural vector autoregressive svar approach to identify the sources of real exchange rate fluctuations in the euro the empirical results indicate that real shocks play a dominant role in explaining the real exchange rate fluctuations in the euro this implies that the best approach for policymakers toward improving the competitiveness of the eu is to focus on improvements in the real economy such as improvements in efficiency technologies and productivity

recreation demand models with taste differences over people we estimate random parameter logit models of anglers choice of fishing site the models generalize logit by allowing coefficients to vary randomly over anglers rather than being fixed the models do not exhibit the restrictive independence from irrelevant alternatives property of logit and can represent any substitution pattern estimation explicitly accounts for the fact that the variation in coefficients over anglers induces correlation in unobserved utility over trips by the same angler willingness to pay for improved fish stock and the value to anglers of specific sites are calculated from the models and compared with the estimates obtained from a standard logit model

the extent of information its relevance for random utility models this paper examines the effect of the researcher s definition of a recreator s choice set on the parameter and welfare estimates from standard random utility models three choice set definitions are compared choice sets based on all alternatives within the survey those alternatives within a specified distance from the respondents home and alternatives familiar to the individual we show that parameter and welfare estimates are sensitive to the definition of the choice set welfare measures of site closures differ in varying ways depending on the familiarity level of the sites in question

modeling overnight recreation trip choice application of a repeated nested multinomial logit model in this paper we apply the repeated nested multinomial logit model a version of a random utility model rum to estimate the choice of an overnight versus single day recreation trip along with the other usual choice of which of the sites to visit and less typically the choice of whether to participate in our application to fish at all we also find statistically significant income effects in the empirical results the application is to atlantic salmon fishing and the data set is for maine resident angler s fishing trips to rivers in maine and canada

large datasets factor augmented and factor only vector autoregressive models and the economic consequences of mrs thatcher we investigate methods of capturing the salient characteristics of very large datasets in an investigation of uk and us macroeconomic policy using factor augmented var favar models we also estimate structural factor only var fovar models and examine the impact of aggregate demand and aggregate supply in a further empirical application we find that while there is some evidence of increased macroeconomic flexibility in the usa as well as the uk since the late 1980s the speed of macroeconomic adjustment is more marked in the uk economy post 1987 possibly reflecting the uk labour market reforms of the thatcher government in the 1980s

is the proposed east african monetary union an optimal currency area a structural vector autoregression analysis summary this paper empirically assesses the suitability of the east african ea countries for a regional monetary union by testing for symmetry of the underlying structural shocks the results indicate that supply and demand shocks are generally asymmetric which does not lend strong support for forming a currency union in the ea region at the moment however the speed and magnitude of adjustment to shocks is similar across the countries therefore further integration of the economies might lead to more favorable conditions for a monetary union although evidence in favor of linking an ea currency to an external anchor is weak such support seems to favor the euro

european monetary union a cointegration analysis this paper employs systems based cointegration techniques developed by johansen 1988 1995 to determine which european union countries would form a successful economic and monetary union emu based on long run behavior of the nominal convergence criteria laid down in the maastricht treaty the original 12 european union countries are analyzed together nominal exchange rates real exchange rates longterm interest rates and government budget deficits are each analyzed for co movements among the 12 countries and various subgroups of them the results suggest that not all of the 12 original countries of the european union could possibly form a successful emu over time unless several countries made significant adjustments

currency preferences purchasing power risks and the determination of exchange rates in an optimizing model most recent research on the theory of exchange rate determination treats the exchange rate as the relative price of two assets domestic money and foreign money the value of an asset depends on the distribution of its return however most of the research has dealt with models in which there is no uncertainty the present paper focuses on questions that cannot be addressed in a world of certainty because in such a world an asset is never risky it investigates how purchasing power risks affect the determination of exchange rates this investigation is pursued in a fairly general optimizing model the present research is related to some recent work in international economics and in financial economics it follows the approach of obstfeld 1981 and stockman 1980 in that it uses an optimizing model and takes into account the role of government transfers in the flow budget constraint of individuals as in calvo and rodriguez 1977 stockman 1980 and others the fact that holdings of foreign monies are useful to domestic individuals is taken into account finally the paper uses techniques developed in papers in the finance literature which build on merton s 1973 asset pricing model and use a concept of equilibrium developed in

trade in risky assets a theory of the international trade pattern in risky assets is developed by applying the law of comparative advantage to asset trade according to this l aw there is a tendency for a country to import assets that have rela tively high autarky prices it is examined how autarky prices are aff ected by international differences in stochastic properties of output endowments the rate of time preference the degree of risk aversion and subjective beliefs and how such differences predict overall ca pital account deficits or surpluses as well as the composition of the capital account into trade in specific risky assets copyright 1988 by american economic association

capital flows investment and exchange rates abstract this paper incorporates international capital flows into a two country monetary general equilibrium model of asset prices with investment and production we calculate theoretical covariances between investment the current account the exchange rate and the terms of trade these covariances depend upon the coefficient of relative risk aversion the magnitude and sign of a country s net international indebtedness other properties of tastes and technologies and the stochastic processes on disturbances to productivity and monetary growth rates international capital flows arise from changes in world wealth and its relative composition in foreign and domestic assets

narrow choice sets in a random utility model of recreation demand we consider the implications of narrow choice sets on welfare estimation in a random utility model of recreation demand we hypothesize that careful formulation of the choice set focusing on the sites of policy interest and their closest substitutes will give reasonably accurate welfare estimates we use nearby sites as close substitutes and treat more distant sites as aggregate alternatives in our application to fishing in maine we find that the welfare estimates are rather sensitive to narrowing choice sets in this manner the sensitivity largely tracts variation in the estimated travel cost coefficient across the different models considered
