This paper estimates annual data on educational attainment for 3,076 mainland U.S. counties 1991-2005. Being estimated without resorting to ancillary information, this data is suited particular well for panel regression analyses. Several plausibility checks indicate that the data is fairly...

Despite favourable ecological and economic results, many developing countries have not yet adopted an integrated pesticide management (IPM). Given rising marginal costs and diminishing marginal benefits from IPM technology transfer, an optimal control framework is used to identify optimal rates...

Motivated by the apparent failure of the credit multiplier mechanism (CM) to deliver amplification in DSGE models, we re-examine its role in business cycles to address the question: is something wrong with the CM? Our answer is no. In coming to this answer we construct a model with reproducible...

Existing evidence from U.S. middle-class households shows that their MPCs out of tax rebates greatly exceed the PIH's prediction and are weakly related to their liquid assets. The standard precautionary-saving model predicts the first fact but counterfactually requires MPCs to decrease with...

The paper investigates by means of cointegration analysis whether the recently observed low levels of private saving and the current account balance in the United States are worrisome in the sense that they cannot be sufficiently explained by determinants which performed well in the past. Stock...

A canonical but untested assumption in economics is that choices are determined only by preferences and budget constraints, but not by how people approach decision making. In particular, it is believed that people behave “as if they optimized”, even if they do not engage in any formal...

This paper indicates that East Germany's unemployment originates primarily in the labor market, caused by the fast wage adjustment after German reunification. We model the resulting labor market traps in a search and matching framework, show that they are difficult to overcome, and provide...

This paper addresses the question of why prolonged regional unemployment differentials tend to persist even after their proximate causes have been reversed (e.g., after wages in the highunemployment regions have fallen relative to those in the low-unemployment regions). We suggest that the...

We introduce unemployment and endogenous selection of workers into different skill-classes in a trade model with two sectors and heterogeneous firms. This allows us to study the distributional consequences and the skill-specific unemployment effects of trade liberalization. We show that the...

We introduce search and matching unemployment into a model of trade with differentiated goods and heterogeneous firms. Countries may differ with respect to size, geographical location, and labor market institutions. Contrary to the literature, our single-sector perspective pays special attention...
