Properties of dynamic stochastic general equilibrium models can be revealed by either using numerical solutions or qualitative analysis. Very precise and intuition-building results are obtained by working with models which provide closed-form solutions. Closed-form solutions are known for a...

After the Hartz reforms of 2003–2005, unemployment in Germany has gone down significantly. Using a structural evaluation, it is shown that the contribution of the Hartz IV reform to this decrease was extremely modest. Hartz IV explains less than 0.1 percentage point of the decline in the...

We investigate how continental European unemployment can be reduced without reducing unemployment benefits and without reducing the net income of low-wage earners. Lower unemployment replacement rates reduce unemployment, the net wage, and unemployment benefits. A lower tax on labor increases...

Existing literature repeatedly documented a strong correlation between trade and growth. It has also shown a causal effect of imports (though not necessarily exports) on growth in simultaneous equation models but to a lesser extent in Granger-causality tests. Export and import taxes have...
