The study of risk management began after World War II. Risk management has long been associated with the use of market insurance to protect individuals and companies from various losses associated with accidents. Other forms of risk management, alternatives to market insurance, surfaced during...

Structured finance is often mentioned as the main cause of the latest financial crisis. We argue that structured finance per se did not trigger the last financial crisis. The crisis was propagated around the world because of poor risk management such as agency problems in the securitization...

The contingent claims analysis of the firm financing often presents a debt renegotiation game with a passive bank which does not use strategically its capability to force liquidation, contrary towhat is observed in practice. The first purpose of this paper is to introduce more strategic bank...

We ask how the three known mechanisms for solving cost sharing problems with homogeneous cost functions - the value, the proportional, and the serial mechanisms - should be extended to arbitrary problem. We propose the Ordinality axiom, which requires that cost shares be invariante under all...

Existing estimates of the welfare cost of business cycles suggest that it is quite low and might well be minuscule. Many of these estimates are based on aggregated U.S. consumption data. Arguably, because markets are incomplete and risk-sharing is imperfect, the welfare costs computed with...

In this paper, we argue that it would be fruitful to revisit foreign aid's potential as an insurance mechanism against macroeconomic shocks. In a simple model of aid flows between two endowment economies, we show that at least three fourths of the large welfare costs of macroeconomic...

This paper proposes a nonlinear impulse-response matching procedure explicitly designed to estimate nonlinear dynamic models, and illustrates its applicability by estimating a macro-fi…nance model of asset pricing under skewness risk. As auxiliary model, a new class of nonlinear vector...

GARCH volatility models with fixed parameters are too restrictive for long time series due to breaks in the volatility process. Flexible alternatives are Markov-switching GARCH and change-point GARCH models. They require estimation by MCMC methods due to the path dependence problem. An unsolved...

We study the effect of dynamic and investment externalities in a one-sector growth model. In our model, two agents interact strategically in the utilization of capital for consumption, savings, and investment in technical progress. We consider two types of investment choices: complements and...
