credit constraints and international financial crises abstract a version of the kiyotaki and moore j political econom 105 1997 211 model of credit cycles is used to examine the extent to which a crisis in a country can spread to another seemingly unrelated country the model features two small open economies that face credit constraints and produce a differentiated commodity which they export to a large country a productivity shock to one of the small open economies triggers an adverse terms of trade shock to the other which is then amplified by credit constraints the paper provides a new perspective on the relationship between terms of trade shocks and the balance of payments that differs from existing models which focus on risk sharing and consumption smoothing in particular it is shown that if financial frictions are present a temporary terms of trade shock can trigger capital outflows and a rapid deterioration in the current account

paired comparison and contingent valuation approaches to morbidity risk valuation abstract this research uses an experimental approach for eliciting consumer valuations of morbidity risk reductions associated with safter chemical products and introduces the paired comparison questions approach to non market valuation in four applications the paired comparisons approach yields higher morbidity valuations than the more familiar contingent valuation approach however both methodologies produce large values of morbidity reduction benefits in comparison to estimates derived from wage hedonic studies explanations for the difference in the estimates and their magnitudes are suggested along with the public policy implications

taxes and labor supply of high income physicians abstract we use the 1983 1985 physicians practice costs and income survey supplemented with federal and state tax rates to estimate the effect of variation in marginal tax rates on work hours for high income physicians we find that self employed physicians are much more sensitive to the marginal tax rate than would be suggested by previous labor supply studies while those who are employees have no discernible sensitivity to marginal tax rates

capital mobility for developing countries may not be so high abstract international capital flows to developing countries have taken on considerable policy importance in recent years there is disagreement however about whether financial capital mobility has become so high that developing countries have little ability to sterilize capital flows this paper reviews several popular methods of estimating the degree of capital mobility for developing countries and shows that they are subject to potentially important upward biases due to inappropriate assumptions concerning the roles of domestic inflation and sterilization corrections for these factors can cut estimates of capital mobility by one half or more

international financial contagion in currency crises abstract this paper examines the role of financial linkages especially through a common creditor in the propagation of emerging market crises during the 1990s using panel probit regressions on 41 emerging market countries it finds that financial linkages played a significant role in the spread of the mexican asian and russian crises the significance of financial linkages emerges after controlling for the role of domestic and external fundamentals trade spillovers and financial weaknesses in the affected countries a strong financial linkage to the crisis country of origin not only substantially raises the probability of contagion but also helps to explain the observed regional concentration of currency crises

use of damage schedules in environmental valuation the case of urban singapore increasing concerns over environmental degradation have amplified the role of environmental economics and the valuation of non pecuniary environmental resources as tools of analysis to facilitate the design of policies to date however environmental valuation methods have continued to be unreliable misleading and contentious as a guide to resource allocations and damage compensations in this paper a damage schedule is developed based on the scales of relative importance translated from people s judgments about values of various environmental damages or losses the variance stable rank method is applied to the paired comparison responses to obtain the scale values as well as the importance of rankings statistical tests of significance are used to determine the level of the agreement among the survey respondents and the degree of correspondence between different respondent groups this will determine the number of relative importance scales required to adequately represent the responses from all respo

substitution effects in the valuation of multiple environmental programs abstract a theoretical framework for understanding substitution and complementary effects between environmental programs is derived a multiple program valuation function is specified and its structure analyzed a maximum likelihood estimator is derived to estimate the parameters of the valuation function using referendum type contingent valuation data the empirical analysis shows that the conventional benefit aggregation approach of independent valuation and summation overstates the benefits of two and three program policies by an average of 24 and 54 respectively

wta estimates using the method of paired comparison tests of robustness the method of paired comparison is modified to allow choices between two alternative gains so as to estimate willingness to accept wta without loss aversion the robustness of wta values for two public goods is tested with respect to sensitivity of the wta measure to the context of the bundle of goods used in the paired comparison exercise and to the scope scale of the public good project there was no statistical difference in wta measures for open space based on independent treatments with different contexts one treatment involved valuing open space within a set of goods with similar value the other treatment involved valuing open space within a choice set of goods which had lower dollar values than open space there was a statistical difference in wta between a permanent expansion in the bus system and a temporary expansion in the bus system we conclude the method of paired comparison appears to be a very promising approach to elicit measures of wta

monetary policy in emerging markets can liability dollarization explain contractionary devaluations abstract in emerging markets external debt is denominated almost entirely in large developed country currencies such as the u s dollar this liability dollarization offers a channel through which exchange rate variation can lead to business cycle instability when firms assets are denominated in domestic currency and liabilities are denominated in foreign currency an exchange rate depreciation worsens firms balance sheets which leads to higher capital costs and contractions in capital spending to illustrate this i construct a quantitative sticky price small open economy model in which a monetary policy induced devaluation leads to a persistent contraction in output in this model fixed exchange rates offer greater stability than an interest rule that targets inflation

market sentiment and macroeconomic fluctuations under pegged exchange rates this paper models changes in market sentiment as a temporary increase in the premium faced by domestic private borrowers on world capital markets the effects of this shock are studied in an intertemporal optimizing framework of a fixed exchange rate economy where firms demand for working capital is financed by bank credit depending on the perceived length of this shock the model is capable of predicting a rise in domestic interest rates capital outflows and a drop in official reserves a reduction in bank deposits and the supply of credit a fall in private consumption a contraction in output and an increase in unemployment these predictions are consistent with observed facts associated with several recent episodes of turbulence on international financial markets

fiscal adjustment and labor market dynamics in an open economy this paper studies the labor market effects of fiscal adjustment in a two sector three good intertemporal framework key features of the model are an informal sector minimum wages unionized labor in the formal economy imperfect labor mobility and public production of intermediate inputs bluxuryq and wait unemployment prevail in equilibrium it is shown that if unions care sufficiently about employment and if the degree of openness is high an increase in the price of government services may reduce unemployment in the steady state a similar result would hold in an efficiency wage setting if the bdisciplinary effectq of unemployment is sufficiently strong d 2004 published by elsevier b v

fundamentals beliefs and financial contagion abstract we study contagion in a model in which financial crises can occur due to both weak fundamentals and adverse self fulfilling expectations contagion emerges only if a crisis in one country leads international investors to rationally update beliefs about fundamentals in other countries but purely expectational crises may be contagious as investors may infer that fundamentals are weak hence the structure of information is crucial the analysis delivers useful lessons for assessing which countries are more vulnerable to contagion which types of crises are more infectious and whether increased transparency ameliorates contagion effects

using contingent pricing analysis to value open space and its duration at residential locations to estimate benefits from open space adjacent to residences this paper blends contingent valuation and conjoint analysis within a housing market context the resulting framework contingent pricing analysis represents the stated preference counterpart to hedonic pricing analysis by asking individuals to state prices for hypothetical housing locations which include an environmental amenity then it asks individuals to state their willingness to pay for a better and longer lasting environmental amenity as an advantage over hedonic pricing analysis it directly isolates willingness to pay results indicate that potentially short lasting open space adds no value while preserved open space adds 5 066 or 5 to housing value

banks and macroeconomic disturbances under predetermined exchange rates abstract as the recent mexican crisis vividly illustrates latin american countries often go through boom bust cycles caused by both domestic policies and external shocks such cycles are typically magnified by weak banking systems which intermediate large capital inflows this paper develops a simple optimizing model to analyze how the banking sector affects the propagation of shocks in particular we show how the world business cycle and shocks to the banking system affect output and employment through fluctuations in bank credit we also analyze the countercyclical use of reserve requirements econometric evidence for chile and mexico supports the main predictions of the model

dollarization of bank deposits causes and consequences abstract this paper assesses the benefits and risks associated with dollarization of bank deposits we provide novel empirical evidence on the determinants of deposit dollarization its role in promoting financial development and on whether dollarization is associated with financial instability we find that a the credibility of macroeconomic policy and the quality of institutions are both key determinants of cross country variations in dollarization b dollarization is likely to promote financial deepening only in a high inflation environment and c financial instability is likely higher in dollarized economies the implications of these findings for financial sector and monetary policies are briefly discussed

capital inflows external shocks and the real exchange rate abstract this paper examines the effects of a fall in world interest rates on capital flows and the real exchange rate in an optimizing framework with imperfect capital markets a permanent fall leads to a steady state reduction in net foreign assets and a real depreciation regardless of whether the country is initially a net creditor or net debtor on impact the real exchange rate appreciates in the net debtor case but may either appreciate or depreciate in the net creditor case the dynamics associated with a temporary shock depend not only on its duration but also on the initial asset position

a primer on financial contagion abstract this paper presents a theoretical framework to highlight possible channels for the international transmission of financial shocks we first review the different definitions and measures of contagion adopted by the literature we then use a simple multi country asset pricing model to classify the main elements of the current debate on contagion and provide a stylized account of how a crisis in one country can spread to the world economy in particular the model shows how crises can be transmitted across countries without assuming ad hoc portfolio management rules or market imperfections finally tracking our classification we survey the results of the empirical literature on contagion

inflationary consequences of anticipated macroeconomic policies budget deficits implying an unbounded present value of government debt are infeasible and hence induce expectations of a future policy change we study how expectations of a policy switch whose timing or mix between expenditure cuts tax increases or increases in money growth rates may be uncertain affect economic dynamics before the switch takes place we are especially concerned with the correlation between changes in the deficit and inflation of particular interest is our finding that timing uncertainty may induce fluctuations in the rate of inflation that seem to be unrelated to the budget deficit at a time when the budget deficit is responsible for inflation

stagflationary effects of monetary stabilization policies a quantitative analysis of south korea this paper presents a macro model of the korean economy that focuses on short run macro economic adjustment and more in particular on the transmission channels of monetary policy between the financial and the real sector of the economy in addition to the usual link between monetary policy and aggregate demand via investment the link between monetary policy and the supply side of the economy via the financing of working capital with borrowed funds is incorporated this link can potentially reverse the short run impact of tight money on inflation and aggregate the impact on output both export prices and domestic prices show a significant sensitivity to cost of financing working capital this credit supply side link gives a stagflationary bias to restrictive credit policies the empirical relevance of this phenomenon is strongly supported by the simulation results derived with the model structurally section 2 of the paper focuses on the real sector part of the model section 3 discusses the financial sector in section 4 different monetary stabilization packages are simulated using the model presented in sections 2 and 3 and alternative policy measures are discussed the simulation runs show strong short run stagflationary effects of tight money policies
