This volume celebrates the innovative and rapidly growing area of economic research known as meta-regression analysis (MRA). * Shows how MRA enables researchers to make sense of disparate economic findings on the same subject. * Develops methods that help researchers to distinguish publication selection from genuine empirical effect. * Applies these methods to topical areas of economic research including: the effect of immigration on wages, minimum wage on unemployment, and gender on salaries. * Helps to bridge the gulf between economic theory and practice. * Written to be accessible to readers with a basic background in empirical economics.
