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...

This paper offers a dynamic model of the foreign exchange market where some investors in the market are more informed than others. By adjusting the proportion of informed investors in the market, it is shown that the disconnect between macroeconomic variables and the exchange rate is sensitive...

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...

This paper aims at establishing a relationship between disparity of information and the probability of speculative attack in explaining the Asian crisis. We apply the general framework of Markov-Switching models to the differential of interest rates (DIR), subsequently in Indonesia and Malaysia....

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...

When Court enforcement is excessively difficult or costly, agents are often able to create «endogenous enforcement mechanisms», that is, to design agreements so that each party finds it optimal to carry them out (self-enforcing implicit contracts), thanks to the threat of sanctions affecting...

This paper reexamines the issue of optimal capital income taxation in an endogenous growth model with overlapping generations. By assuming costly state verification for capital producing projects, we show that the presence of the information asymmetry creates inefficiency in the credit market by...

In a two period overlapping generations economy with asymmetric information, we investigate the interaction between credit market development and human capital accumulation. As is typical, young borrowers supply their endowed unit of labor time to earn wage income which is used as internal...

In recent years, voluntary approaches are expected to function as new environmental protection tools. This article analyzes whether environmental information of firms should be mandatorily disclosed or disclosed voluntarily, where consumers consider the environmental burdens of firms when buying...
