David Card and Alan B. Krueger have made substantial contributions to the field of Labor Ecomics. Their influential work focuses on policy-relevant issues and spans vast and important topics, including: unemployment, minimum wage, migration, measurement error, unions, wage differentials among various groups in the US, labor demand, social insurance, and techlogical change. Card and Krueger have also been extremely influential in ecometrics methodology; they were at the forefront of employing an 'experimental' approach in their research design and implementation. Both of these IZA prize winners have made significant methodological contributions on instrumental variable estimation, measurement error, regression discontinuity methods, and the use of 'natural' experiments. This book provides an overview of their most important work and is divided two main parts: the first section focuses on school quality and the differences in wages across groups in the US; the second part concentrates on the effect of changes in the minimum wage on employment and wage setting. In section introductions, Card and Krueger offer their insight into these two areas and discuss the historical context for their research.
