This paper proposes conditions for the existence and uniqueness of solutions to systems of differential equations with delays or advances in which some variables are non-predetermined. An application to the issue of optimal interest rate policy is then develop in a flexible-price model where...

This paper offers a framework to study commitment and cooperation issues in games with multiple policymakers. To reconcile some puzzles in the recent literature on the nature of policy interactions among nations, we prove that games characterized by different commitment and cooperation schemes...

This paper assesses the optimal level of public debt in a new framework where aggregate fluctuations are taken into account. Agents are subject to both aggregate and idiosyncratic shocks and the market structure prevents them from perfectly insuring against the risk. We find that the optimal...

This paper considers a two-period monetary double auction with incomplete markets of securities and derivatives. Players may share heterogenous beliefs. Short positions in derivatives are constrained by collateral requirements. A central Bank stands ready to lend money or engage in...

Applying regressions on a sample of 18 OECD countries from 1970 to 2009 using new indicators, we find that right-wing governments liberalize more the financial sector that left-wing governments. We show that if a left-wing government accepts to liberalize the financial sector, an increase of...

This paper examines quantity-targeting monetary policy in a two-period economy with fiat money, endogenously incomplete markets of financial securities, durable goods and production. Short positions in financial assets and long-term loans are backed by collateral, the value of which depends on...

This paper studies the U.S. economy from an original point of view: that of the links existing between crisis and war. The first part analyzes the workings of the current crisis, considered to be a “systemic” one. The second part places the U.S. economy at the very heart of this crisis. The...

The financial and economic crisis entails the question of a return to organized societal regulation. After 30 years during which public authority occupied a marginal position, the financial world is begging for a return to some order. Thus, the question to be asked is that of the legitimate...

The banking systems that deal with risk management depend on underlying risk measures. Following the recommendation of the Basel II accord, most banks have developed internal models to determine their capital requirement. The Value at Risk measure plays an important role in computing this...

Regulation and Risk management in banks depend on underlying risk measures. In general this is the only purpose that is seen for risk measures. In this paper, we suggest that the reporting of risk measures can be used to determine the loss distribution function for a financial entity. We...
