We deal with the issue of testing the specification of a regression function. As a leading case, we consider testing for a pure noise model. We study the smallest local alternatives that can be detected asymptotically in a minimax sense. We propose a simple testing procedure that has asymptotic...

The paper examines the redistributive consequences of the economic integration of factor markets. We consider two countries that redistribute income among their residents. The social benefits in each country are financed by a source based tax on capital which is democratically chosen by its...

We study the relationship between ambiguity (which comes into the picture since contracts have to be written in natural language), and contractual incompleteness. The contracting process is modelled as a signalling game between the parties and the judge, with the contract as the signal. The...

We study games played between groups of players, where a given group decides which strategy it will play through a vote by its members. When groups consist of two voting players, our games can also be interpreted as network-formation games. In experiments on Stag Hunt games, we find that that...
