This paper revisits the problem of adverse selection in the insurance market of Rothschild and Stiglitz (1976). We propose a simple extension of the game-theoretic structure in Hellwig (1987) under which Nash-type strategic interaction between the informed customers and the uninformed firms...

This paper revisits the problem of adverse selection in the insurance market of Rothschild and Stiglitz (QJE, 1976). We propose a simple extension of the game-theoretic structure in Hellwig (EER, 1987) under which Nash-type strategic interaction between the informed customers and the uninformed...

The financial crisis of 2007-08 has underscored the importance of adverse selection in financial markets. This friction has been mostly neglected by macroeconomic models of financial frictions, however, which have focused almost exclusively on the effects of limited pledgeability. In this paper,...

We propose a parsimonious model with adverse selection where delinquency, renegotiation, and bankruptcy all occur in equilibrium as a result of a simple screening mechanism. A borrower has private information about her cost of bankruptcy, and a lender may use random contracts to screen different...

The paper explores the fit properties of a class of multivariate Lévy processes, which are characterized as time-changed correlated Brownian motions. The time-change has a common and an idiosyncratic component, to re ect the properties of trade, which it represents. The resulting process may...

This paper constructs a class of multivariate Gaussian marked Poisson processes to model asset returns. The model proposed accommodates the cross section properties of trades, allows for returns to be correlated conditional on trading activity, and preserves the economic intuition of normality...

The traditional multivariate Lévy process constructed by subordinating a Brownian motion through a univariate subordinator presents a number of drawbacks, including the lack of independence and a limited range of dependence. In order to face these, we investigate multivariate subordination,...

This paper presents a theory in which risk-averse heterogeneously talented entrepreneurs are the key agents driving the process of development and modernisation. Entrepreneurial skills are private information, which prevents full risk sharing. In that setup, development to a modern industrial...

Time-changed Brownian motions are extensively applied as mathematical models for asset returns in Finance. Time change is interpreted as a switch to trade-related business time, different from calendar time. Time-changed Brownian motions can be generated by infinite divisible normal mixtures....
