Managerial know-how shapes the productivity of firms by defining the set of available technologies, production choices, and market opportunities. This know-how can be reallocated across countries as managers acquire control of factors of production abroad. In this paper, we construct a quantitative model of cross-country income differences to study the aggregate consequences of international mobility of managerial know-how. We use the model and aggregate data to infer the relative scarcity of this form of know-how for a sample of developing countries. We also conduct policy counterfactuals and find that on average, developing countries gain up to 23% in output and 9% in consumption when they eliminate all barriers to foreign control of domestic factors of production.

Most economies experience episodes of persistent real exchange rate appreciations, when the question arises whether there is a need for intervention to protect the export sector. In this paper we present a model of irreversible destruction where exchange rate intervention may be justified if the export sector is financially constrained. However the criterion for intervention is not whether there are bankruptcies or not, but whether these can cause a large exchange rate overshooting once the factors behind the appreciation subside. The optimal policy includes ex-ante and ex-post interventions. Ex-ante (i.e., during the appreciation phase) interventions have limited effects if the financial resources in the export sector are relatively abundant. In this case the bulk of the intervention takes place ex-post, and is concentrated in the first period of the depreciation phase. In contrast, if the financial constraint in the export sector is tight, the policy is shifted toward ex-ante intervention and it is optimal to lean against the appreciation. On the methodological front, we develop a framework to study optimal dynamic interventions in economies with financially constrained agents.

We examine the extent to which markets enable the provision of housing finance across a wide range of countries. Housing is a major purchase requiring long-term financing, and the factors that are associated with well functioning housing finance systems are those that enable the provision of long-term finance. Across all countries, controlling for country size, we find that countries with stronger legal rights for borrowers and lenders (through collateral and bankruptcy laws), deeper credit information systems, and a more stable macroeconomic environment have deeper housing finance systems. These same factors also help explain the variation in housing finance across emerging market economies. Across developed countries, which tend to have low macroeconomic volatility and relatively extensive credit information systems, variation in the strength of legal rights helps explain the extent of housing finance. We also examine another potential factor--the existence of sizeable government securities markets--that might enable the development of emerging markets' housing finance systems, but we find no evidence supporting that.

Many arguments about decentralization in public goods provision have testable implications for the relationship between decentralization and the level and spatial variability of public goods. This paper explores the empirical relationship between decentralization and environmental public good, water quality in rivers at monitoring stations around the world. It examines pollution levels and spatial variability of pollution within a country for both a local and a regional pollutant. The results suggest higher pollution levels with greater decentralization when fixed effects are included; the evidence is strongest for the regional pollutant, where it might result from interjurisdictional free riding. Federalism is associated with greater spatial variability in pollution within a country, consistent with the traditional view that decentralization allows policies more tailored to local conditions.

In this paper, we construct a parsimonious overlapping generations model of human capital accumulation, and study its quantitative implications for the evolution of the U.S. wage distribution from 1970 to 2000. One of the key features of the model is that individuals differ in their ability to accumulate human capital, which is the main source of wage inequality in this model. We examine the response of this model to skill-biased technical change (SBTC), which is modeled as an increase in the trend growth rate of the price of human capital starting in early 1970's. Due to the heterogeneity in ability and age, the responses of different individuals to SBTC are systematically different from each other, generating rich behavior in the evolution of relative wages. We consider different scenarios regarding how individuals' expectations evolve during SBTC. Specifically, we study the case where individuals immediately realize the advent of SBTC (perfect foresight); and the case where they initially underestimate the future growth of the price of human capital (pessimistic priors), but learn the truth in a Bayesian fashion over time. Lack of perfect foresight appears to have little effect on the main results of the paper. The model is quantitatively consistent with several trends including the rise in overall wage inequality; the fall and rise in the college premium; the rise in within-group inequality; the stagnation in median wage growth, and the small rise in consumption inequality despite the large rise in wage inequality. Overall, the model shows promise for explaining disparate trends in the evolution of the wage distribution in a unifying human capital framework.
