This primer aims to provide IMF macroeconomists with the essential information they need to address issues concerning health sector policy, particularly when they have significant macroeconomic implications. Such issues can also affect equity and growth and are fundamental to any strategy of...

Since the seminal work by Rothschild and Stiglitz on competitive insurance markets under adverse selection the problem of non-existence of equilibrium hat puzzled many economists. In this paper we approach this problem from an evolutionary point of view. In a dynamic model insurance companies...

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 [28]. We propose a simple extension of the game-theoretic structure in Hellwig [14] under which Nash-type strategic interaction between the informed customers and the uninformed firms results...

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...

This primer aims to provide IMF macroeconomists with the essential information they need in situations where they must address issues concerning health sector policy and when they have significant macroeconomic implications. Such issues can also affect equity and growth and are fundamental to...

Many Asian countries (such as China, Singapore, Korea, Thailand, Malaysia, Indonesia, India, and the Philippines) will experience a significant aging of their populations during the next several decades. This paper explores how these aging Asian countries are addressing and anticipating the...

The 2001 Nobel Prize award to three American scientists for their theoretical contribution to analysis of markets with asymmetrical information has reawakened debates on the behavior and decision-making of economic players under uncertainty. Because insurance is a classic example of such...

The paper analyzes the risk disclosure quality in the prospectus of IPOs in Germany between 2006 and 2008. Quality of risk information is measured as precision and comprehensibility. The relationship between risk disclosure quality and earnings power is tested.

We introduce a two-period general equilibrium model with uncertainty and incomplete financial markets, where default is allowed and agents face in case they do default an utility penalty, which is their own private information. In this setting, if agents have heterogeneous characteristics they...
