This paper develops a sufficient-statistic formula for the unemployment gap-the difference between the actual unemployment rate and the efficient unemployment rate. While lowering unemployment puts more people into work, it forces firms to post more vacancies and to devote more resources to...

Building on the automatic fiscal stabilisers literature, this paper assesses how automatic stabilisers have evolved over the past two decades by analysing changes in the personal income tax and social benefit systems. In three-quarters of the 35 OECD countries analysed, indicators of the...

The output gap is a key variable of business cycle analysis and policy. Obtaining reliable estimates for it, is very difficult, though. Most real-time estimates are frequently revised over time. The idea of this paper is to use various indicators, for example from business surveys, that (i) were...

This chapter develops a toolkit of neoclassical macroeconomic models, and applies these models to the US economy from 1929 to 2014. We first filter macroeconomic time series into business cycle and long-run components, and show that the long-run component is typically much larger than the...

In the Great Recession most OECD countries used short-time work (publicly subsidized working time reductions) to counteract a steep increase in unemployment. We show that short-time work can actually save jobs. However, there is an important distinction to be made: While the rule-based component...
