Real wages are a key determinant of marginal costs. The latter themselves are a driving force of inflation. We ask how wages and labor market shocks feed into the inflation process. We model search and matching frictions in the labour market in an otherwise standard New-Keynesian closed economy...

Having the high unemployment in Germany in mind, this book discusses how macroeconomic theory has evolved over the past forty years. It shows that in recent years a convergence has taken place, with modern models embodying a Keynesian transmission mechanism, monetarist policy implication, and...

Exploiting results from the literature on non-parametric identification, we make three methodological contributions to the empirical literature estimating the matching function, commonly used to map unemployment and vacancies into hires. First, we show how to non-parametrically identify the...

Labor market theories allowing for search frictions make marked predictions on the effect of the degree of frictions on wages. Often, the effect is predicted to be negative. Despite the popularity of these theories, this has never been tested. We perform tests with matched worker-firm data. The...
