We study endogenous uncertainty stemming from the introduction of new financial assets, so as to evaluate the risks as well as the welfare gains of financial innovation. The introduction of financial assets to hedge individual risk can lead to the risk of default, which is a collective risk. The...

In this paper we study the introduction of new assets which are oftenly observed to be defined in expected values rather than state by state, called the Arrow-Lind-Malinvaud (ALM) assets. We demonstrate that individual default emerges naturally in an economy where such ALM assets are introduced...

This paper develops a model of speculative trading in a large economy with a continuum of investors. In our model the investors are assumed to have diverse beliefs which are rational in the sense of being compatible with observed data.We demonstrate the existence of price amplification effects...

In a three-period model with active and passive external corporate governance, this paper studies the endogenous decision of debt and equity financiers on the governance mode and intensity over their debtors, as well as how this may affect the funded firms' financing choice. We show that debt...

We develop a model of asset trading with financial leverage in an economy with a continuum of investors. The investors are assumed to have diverse and rational beliefs in the sense of being compatible with observed data. We show that an increase in leverage ratio may cause the stock price to...

This paper views uncertainty and economic fluctuations as being primarily endogenous and internally propagated phenomena. The most important Endogenous Uncertainty examined in this paper is price uncertainty which arises when agents do not have structural knowledge and are compelled to make...
