We consider a general economy, where agents have private information about their types. Types can be multi-dimensional and potentially interdependent. We show that, if the interim distribution of types is common knowledge (the exact number of agents for each type is known), then a mechanism...

In this paper we provide a political game where agents decide whether to become legislators or politicians. Legislators determine the political institutions constraining politicians' behavior and politicians compete for gaining the power to make decisions about the level of the public good. We...

This paper considers an economy with a public good where a decision must be made both about the level of the public good and the taxation imposed on each citizen (multidimensional policy space). In this context, we derive two interesting results: i) we show that a Nash equilibrium exists under...

We develop a theoretical model to explain why some issues of convertible bonds include a call feature whereas others do not and then test the predictions of the model empirically. The reasoning in the model is that good firms do not need a call feature and therefore issue straight debt or...

We develop a model that explains two stylized facts - the coarseness of credit ratings relative to the underlying default probabilities, and the countercyclical nature of ratings imprecision. The imprecise nature of coarse ratings arises from the revenue-maximizing behavior of rating agencies,...

In this paper we describe a model of optimal investment of various types of financially constrained firms. We show that the resulting relationship between internal funds and investment is non-monotonic. In particular, the magnitude of the cash flow sensitivity of the investment is lower for...

This paper examines the predictability of exchange rates on a transaction level basis using both past transaction prices and the structure of the order book. In contrast to the existing literature we also recognise that the trader may be subject to (Knightian) uncertainty as opposed to risk...

We study single period asset allocation problems of the investor who maximizes the expected utility with respect to non-additive beliefs. The non-additive beliefs of the investor model the presence of an uncertainty and they are assumed to be consistent with the Maxmin expected utility theory of...
