mexico and the brady plan mexico has throughout the 1980s been centre stage in the debates and events shaping the sovereign debt problem caught between a sudden collapse of its terms of trade and rising world interest rates mexico suspended debt service payments in august 1982 and ushered in what has since become known as the debt crisis in the following years lending to ldcs dried up and debtor countries were increasingly forced to run high trade surpluses to effect ever growing transfers from poor back to rich countries in the face of falling growth rates and rising inflation in the high debt countries then secretary of the treasury baker proposed the baker plan in return for economic reforms high debt countries would get new access to medium term new loans in addition to rolling over of amortization of old loans new loans had to come both from commercial creditors and the official lending institutions with access to capital markets restored the economic reforms would it was hoped allow the debtors to grow out of debt but experience in the high debt countries showed that the original hopes of the proponents of the baker plan went unfulfilled net transfers out of the borrowing countries went up rather than down as

trade reforms credibility and development abstract this paper analyzes the implications of uncertainty regarding the future course of trade liberalization on investment and policies uncertainty concerning the future tariff rate is shown to depress saving and to operate as a subsidy tax on inward outward investment we identify the need to tax subsidize private investment in the importable exportable sector the elimination of sectorial private investment policies calls for a rise drop in the public private capital ratio in the outward oriented inward oriented activities in the presence of an external credit ceiling a higher degree of risk aversion increases the magnitude without changing the nature of the policies

explaining male wage inequality in the philippines non parametric and semiparametric approaches the study examines the roles of experience and education in explaining the increase in wage inequality among philippine male workers between 1988 and 1995 it also provides a methodological approach to the analysis of wage inequality by combining non parametric methods with semiparametric additive models using the variance accounting framework non parametric density estimators allow flexibility in dealing with distributional inference while additive models yield marginal effects estimates under minimal assumptions on the functional specification of the wage schooling and wage experience relationships the results show that much of the inequality increase from 1988 to 1995 was caused by greater variabilities in returns to schooling and experience among 1995 workers the rise of the p90 p10 percentile ratio was caused by greater return variabilities on schooling and experience in the 90th percentile

can a liberalization of capital outflows increase net capital inflows abstract facing massive capital inflows that put downward pressure on the real exchange rate some policymakers and analysts have recommended a liberalization of capital outflows empirically however the removal of capital outflow controls has apparently stimulated a net inflow of capital in several experiences such as britain since 1979 italy new zealand and spain in the mid to late 1980s and colombia egypt and mexico in the 1990s numerous measures to liberalize capital outflows in chile during the 1990s have not had a noticeable effect in offseting a surge of net capital inflows how can we explain the apparent paradox that reducing controls on capital outflows can actually increase net capital inflows our theoretical model provides one such explanation a liberalization of capital outflows understood here as a reduction in the minimum capital repatriation period for foreign investment reduces the degree of irreversibility of the decision to invest in a given country this in turn lowers the option value of waiting until uncertainty about a possible change in the rules of the game that affect investment in domestic assets is resolved because in this event foreigners investing at home will be stuck with the low return asset for a shorter period of time thus a reduction in the minimum repatriation period is likely to increase not decrease net capital inflows this result has an important policy implication liberalizing capital outflows may have significant benefits on its own but it may not be the appropriate policy to defend the real exchange rate in the presence of massive capital inflows because it is likely to strengthen those very capital inflows

the tragedy of the commons and economic growth why does capital flow from poor to rich countries we analyze a differential game in which all interest groups have access to a common capital stock we show that the introduction of a technology that has inferior productivity but enjoys private access may ameliorate the tragedy of the commons we use this model to analyze capital flight in many poor countries property rights are not well defined since safe bank accounts in rich countries the inferior technology are available to citizens of these countries they engage in capital flight we show that the occurrence of capital flight does not imply that opening the capital account reduces growth and welfare

a rudimentary random matching model with divisible money and prices abstract we consider a version of kiyotaki and wright s monetary search model in which agents can hold arbitrary amounts of divisible money a continuum of stationary equilibria indexed by the aggregate real money stock exists with all trading occurring at a single price there is always a maximum level of the real money stock consistent with existence of such an equilibrium in the limit as trading becomes faster relative to discounting any real money stock becomes feasible in such an equilibrium in contrast to the original kiyotaki wright model higher equilibrium real money stocks unambiguously correspond to higher welfare in this costless production environment journal of economic literature classification numbers d51 e40

policies to move from stabilization to growth although some discussions of stabilization see growth as more or less an assured product of appropriate stabilization this paper argues that there is no guarantee that stabilization will lead to growth it may result in stagnation the paper discusses the essentials of stabilization including inflation targets fiscal policy monetary policy exchange rates and incomes policy and suggests that two areas of structural reform deregulation including trade reform and reform of the financial sector can play a central role in the long run success of a stabilization effort the paper concludes that countries that have experienced protracted high inflation financial instability and payments crises probably will have a difficult and protracted transition to growth and that external resources will be necessary as a continuing feature of the transition sustained external support in the form of long term loans heavily conditioned on the tangibility and credibility of domestic progress in adjustment will help provide a bridge by which flight capital may return and foreign direct investment may be encouraged to take advantage of fresh opportunities

capital flight under uncertainty about domestic taxation and trade liberalization abstract this paper analyses in a simple general equilibrium framework how uncertainty regarding the future level of domestic taxes on factor incomes and regarding trade liberalization in an economy contemplating tariff reforms affects the overall volume of domestic investment and capital flight it is a variation of the alesina tabellini model alesina a tabellini g 1989 external debt capital flight and political risk journal of international economics 27 and brings out the importance of income effects in addition to substitution effects in determining how the volume of capital flight responds to changes in key policy uncertainty parameters

trade taxes and the current account abstract we show that under some conditions a temporary import tariff improves the current account whereas a temporary export tax deteriorates it permanent import tariffs and export taxes have an identical although ambiguous effect on the current account

real exchange rates and macroeconomics a selective survey the paper discusses real exchange rate issues of industrial and of developing countries for real exchange rates among the key industrial countries we ask what is the best conceptual framework to shed light on this question we look at alternative theoretical approaches and at empirical evidence on the relation among interest rates expectations and depreciation the discussion of developing countries real exchange rates focuses on the link between real exchange rates real wages and the profitability of capital the model highlights the discrepancy between the mobility of capital including in the long run physical capital and

a divisible search model of fiat money this paper extends the kiyotaki wright search model of fiat money to allow for divisible money and goods the extension allows me to examine the standard issues in monetary economics such as the neutrality and superneutrality of money by severing the artificial link in the kiyotaki wright model between the money supply and the number of money holders it is shown that money is neutral but not superneutral money growth generates a trading opportunity effect it changes the fraction of different agents in the economy and hence changes the probability with which agents have a successful match in addition money growth has a negative effect on the real money balance that is familiar in walrasian monetary models the balance of the two effects can imply a positive optimal money growth rate

search bargaining money and prices the goal of this paper is to extend existing search theoretic models of fiat money which until now have assumed that the price level is exogenous by explicitly incorporating bilateral bargaining this allows us to determine the price level endogenously and leads to additional insights concerning the role of money for example we find that monetary equilibria are generally inefficient in the sense that output and prices differ from the solution to a social planner s problem although the difference can become small as the discount rate or search friction vanishes we also find that there exist nonstationary inflationary equilibria

dynamic auction markets with fiat money in this paper we consider various types of models where fiat money is used to facilitate trades and investigate whether models with fiat money have the same equilibrium allocations in particular we investigate whether or not such models have a continuum of stationary equilibria we first present a dynamic centralized auction market model with money which has not been investigated in the literature we compare its outcome with that of walrasian models with cash in advance constraints and show that the outcomes are very different the walrasian markets model has determinate stationary equilibria and the auction markets model has a continuum of stationary equilibria moreover we also build models on decentralized auction markets and on decentralized markets with bargaining and obtain results similar to those of the dynamic centralized auction markets model

large scale privatization in transition economies to explain the slow progress of mass privatization programs in eastern europe the authors present a model based on a positive spillover between aggregate privatization and the individual expected return to privatization derived from a potential populist backlash if costly reforms do not bring forth sufficient aggregate privatization the model allows for the simultaneous existence of a pessimistic zero privatization trap and an optimistic full privatization equilibrium defined by a critical mass of expected privatization while both privatization subsidies and minimum income guarantees can by themselves secure coordination on the optimistic equilibrium the financing constraint may offset the direct effect copyright 1993 by american economic association

unconditional quantile regressions wage growth and inequality in the philippines 2001 2006 the contribution of covariates i implement a two stage procedure to estimate the components of real wage change in the philippines along the wage distribution from 2001 to 2006 as well as the contribution of individual covariates to each component the methodology is based on re centred influence functions rif as suggested by firpo et al 2009 the advantage of this methodology is that it not only decomposes the unconditional wage change at any quantile of the wage distribution but also allows the characterization of the contribution of any single covariate on each component i find that real earnings of males in the philippines declined and the decline along the earnings distribution is generally higher at higher deciles for all males and higher at lower deciles in manila decomposition results are driven by the wage structure component while the composition effect is small and generally positive with education as the main contributor within the wage structure effect the main determinants are associated with changes in the r

on the multiplicity of monetary equilibria green zhou meets lagos wright abstract green and zhou relax the assumption made in early search based models of monetary exchange of indivisible money their paper and various extensions make much technical progress and derive some interesting substantive results in particular they show there is an indeterminacy of steady state monetary equilibria we reconsider this result in the framework of lagos and wright which is more tractable we show that a similar multiplicity arises and is much easier to derive and understand we also compare the results to those in related nonmonetary models and discuss how they depend on details including the number of agents and the timing

money and price dispersion we relax restrictions on the storage technology in a prototypical monetary search model to study price dispersion in this case buyers and sellers enter matches with potentially different willingness to trade across the distribution of possible bilateral matches prices generally will differ even though agents have identical preferences and technologies we provide existence conditions for a particularly simple equilibrium pattern of exchange we prove that in the limiting case where search frictions are eliminated equilibrium prices are uniform we also show that a higher initial money stock can raise the average price level and increase price dispersion

decomposing changes in wage distributions a unified approach over the last fifteen years many researchers have attempted to explain the determinants and changes of wage inequality i propose a simple procedure to decompose changes in the distribution of wages or in other distributions into three factors changes in regression coefficients the distribution of covariates and residuals the procedure requires only estimating standard ols regressions augmented by a logit or probit model it can be extended by modelling residuals as a function of unmeasured skills and skill prices two empirical examples showing how the procedure works in practice are considered in the first example sources of differences in the wage distribution in alberta and british columbia are considered in the second sources of change in overall wage inequality in the united states 1973 99 are re examined finally the proposed procedure is compared with existing procedures jel classification j3 la decomposition des changements dans les distributions de salaires une approche unifee au cours des quinze dernieres annees nombre d etudes se sont penchees sur les determinants et les changements de la distribution des salaires ce memoire propose une procedure pour decomposer les changements de la distribution des salaires en trois elements les changements dans les coefficients de regression la distribution des regresseurs et les changements residuels cette procedure ne necessite que l estimation de regressions par moindre carres ordinaires et d un modele probit ou logit l auteur montre aussi comment modeliser les residus en fonction de competences non mesurees la procedure proposee est mise en application dans le contexte de deux exemples la distribution des salaires en alberta et en colombie britannique et les changements dans la distribution des salaires de 1973 a 1999 aux etats unis le memoire examine aussi comment cette procedure se compare aux methodes proposees par d autres chercheurs

credibility of trade policy reform and investment the mexican experience abstract this paper assesses whether the program of trade liberalization undertaken by mexico after 1985 was undermined by lack of credibility it provides an empirical counterpart to some of the credibility issues that have been discussed elsewhere in the literature and proposes a methodology based on the estimation of a probit model to measure the probability of trade policy reversal due to the likelihood of occurrence of a balance of payments crisis it is shown that the probability of trade policy reversal reduced indeed the rate of capital accumulation during the first years of the reform

equilibrium price dispersion in a matching model with divisible money the main purpose of this paper is to show that for any given parameter values an equilibrium with dispersed prices two price equilibrium exists in a simple matching model with divisible money presented by green and zhou 1998 we also show that our two price equilibrium is unique in certain environments moreover the welfare effect of price dispersion is analysed

on money as a medium of exchange we analyze economies in which individuals specialize in consumption and production and meet randomly over time in a way that implies that trade must be bilateral and quid pro quo nash equilibria in trading strategies are characterized certain goods emerge endogenously as media of exchange or commodity money depending both on their intrinsic properties and on extrinsic beliefs there are also equilibria with genuine fiat currency circulating as the general medium of exchange we find that equilibria are not generally pareto optimal and that introducing fiat currency into a commodity money economy may unambiguously improve welfare velocity acceptability and liquidity are discussed

trade reform aggregate investment and capital flight on credibility and the value of information abstract in this paper we demonstrate that uncertainty about future policy reversals coupled with irreversible investment confers an option value to foreign exchange and may lead to capital flight and a fall in aggregate investment after a trade reform the analysis focuses on the value of information and the credibility of the policy reform the conclusion points to a potential role for international institutions to prevent such problems

increasing wage dispersion and the changes in relative employment and wages in mexico s urban informal sector 1987 1993 this study analyses the role of changes in informal formal relative employment wage levels and wage inequality in explaining increasing wage dispersion in mexico during the 1987 1993 period from 1987 to 1993 the variance of the log of hourly wages for mexican workers increased by more than 50 per cent using data from the encuesta nacional de empleo urbano we find that this increase in the overall wage dispersion was mainly driven by increasing wage dispersion in the formal sector coupled with a faster growth in formal sector employment as a percentage of total employment however compression in the distribution of wages within the informal sector contributed to substantially slowdown the increasing overall wage inequality about 60 per cent of the 1987 1993 4 65 percentage point reduction in the informal sector share of total employment is explained by changes in the structure that determines sectoral employment the rest is explained by changes in the composition of the labour force particularly in

the investment strategies for a dynamic supply chain under stochastic demands abstract a successful supply chain management scm should aim to maximize the net present value of joint profits along the supply chain however the volatile market conditions cause the future cash flows along the supply chain more difficult to anticipate to obtain higher supply chain value the supplier and the retailer should cooperatively determine the optimal entry time this paper proposes a two stage dynamic optimization model by using a real option approach and then performs the sensitivity analyses for the option value and the investment threshold the impacts of some critical factors including the growth rate and the volatility of demand shock sunk cost and relating operational costs cost rates fix costs holding costs of inventory and shipping costs are investigated

nonparametric regression techniques in economics this introduction to nonparametric regression emphasizes techniques that might be most accessible and useful to the applied economist the paper begins with a brief overview of the class of models under study and central theoretical issues such as the curse of dimensionality the bias variance trade off and rates of convergence the paper then focuses on kernel and nonparametric least squares estimation of the nonparametric regression model and optimal differencing estimation of the partial linear model constrained estimation and hypothesis testing is also discussed empirical examples include returns to scale in electricity distribution and hedonic pricing of housing attributes

empirical age earnings profiles the human capital earnings function in which earnings are expressed as a quadratic in potential experience is probably the most widely accepted empirical specification in economics in spite of its widespread acceptance the human capital earnings function provides a very poor approximation of the true empirical relationship between earnings and experience the standard formulation understates early career earnings growth by about 30 50 and overstates midcareer growth by 20 50 however simple alternative specifications that fit the data are available

macroeconomic uncertainty and private investment abstract this paper provides empirical support for a link between macroeconomic uncertainty and private investment in developing countries cross section regressions with constructed measures of uncertainty confirm that for developing countries uncertainty is negatively correlated with private investment

animal spirits investment and international capital movements abstract in the aftermath of the debt crisis developing countries are endeavoring to repatriate flight capital and to resume domestic private investment yet investment and the associated capital inflows continue to be disappointing and highly uneven over time in many cases this paper provides a model of investment and capital movements in and out of such countries central to the paper is the introduction of fiscal increasing returns to domestic capital into a standard dynamic optimizing model the resulting system may display multiple steady states and surprising dynamic behavior initial conditions and expectations both matter in selecting the equilibrium on which the economy converges for some initial conditions animal spirits can determine the course of investment and capital flows a limit cycle may occur around one of the welfare inferior equilibria along that cycle capital stocks and relative prices display endogenous fluctuations

a compound option model of production and intermediate inventories this article extends the option approach to valuing real assets by modeling the firm as a two stage process with bounded output rates in which the output of the first stage may be held as work in process in this setting the real asset becomes a compound option which if exercised gives the option to finish the work in process and sell the output as its final payoff the existence of intermediate inventories may arise as an optimal investment strategy for exploiting possible future price increases the framework allows us to analyze the effect of uncertainty on output rates and the effect of interest rates changes on inventory levels copyright 1993 by university of chicago press

debt crisis adjustment policies and capital formation in developing countries where do we stand abstract this paper documents the decline in investment rates observed in developing countries after 1982 and explores analytically and empirically the factors contributing to explain it the paper focuses on the impact of macroeconomic adjustment and reform measures on private investment particularly in latin america and east asia and underscores the importance of macroeconomic uncertainty policy credibility and potential coordination failures in shaping the response of investment to the changes in economic incentives brought about by structural reforms the analysis concludes with some policy recommendations to improve the design of sustainable growth oriented adjustment programs

private investment under uncertainty in ghana abstract ghana s economic recovery program saw considerable growth of the economy during 1985 1991 this commendable performance slackened after 1992 a fact which is attributable to poor private investment response following reform this article shows that the poor growth in private investment may be attributed to the perception of uncertainty in the political and economic environment since 1982 the uncertainty is derived from the low credibility of government as it has been unable to assure investors that earlier decisions that showed a bias against private wealth will not be repeated economic incentives arising from reforms do not provide guarantees against poor credibility

money and prices a model of search and bargaining abstract this paper makes commodities divisible and incorporates bargaining into the search theoretic model of money to determine the purchasing power of money or price it is shown that two monetary equilibria always coexist where fiat money is universally accepted the two equilibria differ in price output welfare and the velocity of money sunspot monetary equilibria exist in which money is universally accepted in all states of the economy multiplicity has novel implications on the effectiveness of currency substitution and exchange market intervention journal of economic literature classification numbers c78 e40

nigeria during and after the oil boom a policy comparison with indonesia nigeria and indonesia provide an interesting contrast with regard to performance and policy during and after the oil boom roughly a decade after the first oil shock nigeria is faced with several economic problems including a serious decline in its agricultural sector and a deteriorating external debt situation while some decline in the nonoil traded goods sector reflects efficient adjustment to the oil boom policy with regard to public expenditure exchange rates pricing and the trade regime could exacerbate such decline and impede readjustment as the boom subsides the links between oil prices deficits inflation and real exchange rate appreciation are analyzed and nigerian and indonesian fiscal and exchange rate and agricultural and foreign borrowing strategies are compared it is concluded that with the exception of cuts in the deficit since 1984 nigerian policy following the boom has not been conducive to adjustment to the current period of low oil prices and high real interest rates corrective measures and policy options are discussed

parametric and semiparametric model representations of the conditional mean of wages do they make a difference against nonparametric ones this study is concerned with the validation of parametric functional representations of the conditional mean of wages using philippine data this is done in the light of studies confirming relative

liquidity a new monetarist perspective this essay surveys the new monetarist approach to liquidity work in this literature strives for empirical and policy relevance plus rigorous foundations questions include what is liquidity is money essential in achieving desirable outcomes which objects can or should serve in this capacity when can asset prices differ from fundamentals what are the functions of commitment and collateral in credit markets how does money interact with credit and intermediation what can and should monetary policy do the research summarized emphasizes the micro structure of frictional transactions and studies how institutions like monetary exchange credit arrangements or intermediation facilitate the exchange process

contingent prices and money price posting with directed search is a widely used trading mechanism coles and eeckhout showed that if sellers are allowed to post prices contingent on realized demand instead of one price then there is real market indeterminacy in this article we fit this contingent price posting protocol into a monetary economy we show that as long as holding money is costly there exists a unique equilibrium rather than a continuum in this equilibrium sellers post a low price for when the buyer is alone a high price for when several buyers show up and buyers randomize between sellers and money holdings

capital repartriation and the waiting game abstract a stylized fact on post stabilization economies is that getting the fundamentals right even though necessary is not sufficient to ensure a prompt and costless resumption of growth uncertainty whether stabilization can in fact be sustained confers an option value to postponing investment in domestic real assets
