That institutions matter is widely accepted among economists and so are social norms as an important category of informal institutions. Social norms matter in many economic situations, but in particular for markets. The economic literature has studied the interrelation between markets and social...

The Great Recession and the resulting European debt crisis revived a debate about deeper fiscal integration in the Eurozone. We discuss different alternatives how an unemployment insurance system for the euro area could be designed and run counterfactual simulations based on micro data to...

The assumptions that subjects hold beliefs and that the chosen actions are not altered by a proper elicitation of these beliefs are widely used in economics. In this paper I experimentally test whether the second assumption is correct. Especially controlling for different game properties, I nd...

For a repeated procurement problem, we compare two stylized negotiating cultures which differ in how the buyer uses an entrant to exert pressure on the incumbent resembling U.S. style and Japanese style procurement. In each period, the suppliers are privately informed about their production...

We study the effect of international trade and freeness of trade on interregional inequality within countries. We estimate a model derived from a structural economic geography approach where interregional inequality depends on weighted trade shares and trade costs and where we can derive an...

Does granting citizenship at birth help immigrant children to integrate in the host country's educational system and thus, to promote their educational success? Our identification strategy is based on a reform of the German naturalization law in 2000. We exploit this natural experiment and use a...

Ever since Sjaastad (1962), researchers have struggled to quantify the psychic cost of migration. We monetize psychic cost as the wage premium for moving to a culturally different location. We combine administrative social security panel data with a proxy for cultural difference based on unique...

This paper is among the first to link internal migration and subjective well-being in developed countries. Economic theory predicts that individuals migrate towards urban agglomerations, if the potential gain in income is sufficient to cover costs. However, this narrow view cannot explain why...

We apply an in nite horizon intertemporal optimization model to a simple speculative attack framework. Thereby, the central bank faces a one control two-state variables optimization problem with endogenuous exit. By setting the interest rate the central bank can stimulate the economy or fend o...

In the 2000s, China's WTO entry constituted a major trade shock. In this paper, we analyze its eff ects on trade and value chains. The fragmentation of the global value chain makes it hard to disentangle who produces for whom. Value added trade contains this information. We build a multi-sector...
