In this paper, we continue to explore the equilibrium theory under ambiguity. For a model of a pure exchange and asymmetric information economy with a measure space of agents whose exogenous uncertainty is described by a complete probability space, we establish a representation theorem for a...

In this paper, we study asymmetric information economies consisting of both non-negligible and negligible agents and having ordered Banach spaces as their commodity spaces. In answering a question of Herves-Beloso and Moreno-Garcia in [17], we establish a characterization of Walrasian...

The literature analyzing games where some players have private information about their "types" is usually based on the duality of "good" and "bad" types (GB approach), where "good" type denotes the type with better quality. In contrast, this paper analyzes a signalling game without types...

This paper analyzes debt-equity choice for financing a two-stage investment when a firm’s insiders have private information about the firm’s expected earnings. When private information is one-dimensional (for example when short-term earnings are common knowledge while long-term earnings are...

We build a model of an IPO for firms with private information about their earnings profile over time and test the model’s predictions using a complete sample of newly listed Chinese companies between 1992 and 2007. The model predicts that IPO size is positively correlated with short-term...

This paper shows that asymmetric information about the timing of earnings can affect corporate capital structure. It sheds some new light on two following questions: why may profitable firms be interested in issuing equity, and why does debt not necessarily signal a firm quality. These issues...

In this paper, we establish two different characterizations of Walrasian expectations allocations by the veto power of the grand coalition in an asymmetric information economy having finitely many agents and states of nature and whose commodity space is a Banach lattice. The first one deals with...

The modern literature on city formation and development, for example the New Economic Geography literature, has studied the agglomeration of agents in size or mass. We investigate agglomeration in sorting or by type of worker, that implies agglomeration in size when worker populations differ by...

The empirical literature has found evidence of locational sorting of workers by wage or skill. We show that such sorting can be driven by asymmetric information in the labor market, specifically when firms do not know if a particular worker is of high or low skill. In a model with two types and...
