Poverty remains one of the greatest problems of our time, causing starvation and humiliation in poor countries and contributing to problems of conflict, migration and environmental degradation effecting also richer countries. This study provides a systematical analysis of today’s donor strategies for development cooperation, which unite around the goal of poverty reduction. The most recent strategies of the World Bank and the German, British and Swedish official development agencies are compared and evaluated. Their broad consensus on goals and conceptual elements is comprehensively presented. Differences in accentuations regarding beneficiaries and implementation methods are highlighted. An empirical study of the poverty focus in project evaluations of the German Financial Cooperation rounds off the analysis by exemplarily pointing at the practical implications of the new strategies.

We develop a neoclassical trade model with heterogeneous factors of production. We consider a world with two factors, labor and "managers", each with a distribution of ability levels. Production combines a manager of some type with a group of workers. The output of a unit depends on the types of the two factors, with complementarity between them, while exhibiting diminishing returns to the number of workers. We examine the sorting of factors to sectors and the matching of factors within sectors, and we use the model to study the determinants of the trade pattern and the effects of trade on the wage and salary distributions. Finally, we extend the model to include search frictions and consider the distribution of employment rates.

Demand for insurance can be driven by high risk aversion or high risk. We show how to separately identify risk preferences and risk types using only choices from menus of insurance plans. Our revealed preference approach does not rely on rational expectations, nor does it require access to claims data. We show what can be learned non-parametrically from variation in insurance plans, offered separately to random cross-sections or offered as part of the same menu to one cross-section. We prove that our approach allows for full identification in the textbook model with binary risks and extend our results to continuous risks. We illustrate our approach using the Massachusetts Health Insurance Exchange, where choices provide informative bounds on the type distributions, especially for risks, but do not allow us to reject homogeneity in preferences.

This essay surveys the literature on directed/competitive search, covering theory and applications in, e.g., labor, housing and monetary economics. These models share features with traditional search theory, yet differ in important ways. They share features with general equilibrium theory, but with explicit frictions. Equilibria are typically efficient, in part because markets price goods plus the time required to get them. The approach is tractable and arguably realistic. Results are presented for finite and large economies. Private information and sorting with heterogeneity are analyzed. Some evidence is discussed. While emphasizing issues and applications, we also provide several hard-to-find technical results.
