We analyze the impact of funding costs and margin requirements on prices of index options traded on the CBOE. We propose a model that gives upper and lower bounds for option prices in the absence of arbitrage in an incomplete market with differential borrowing and lending rates. We show that...

In spite of the fact that they can draw on a larger, more liquid and more diversified pool of capital than the equity of reinsurance companies, financial markets have failed to displace reinsurance as the primary risk-sharing vehicle for natural catastrophe risk. We show that this failure can be...

Over the period 2002 to 2003, Switzerland and the European Union (EU) were engaged in negotiations regarding banking secrecy. The EU's stated goal was for Switzerland to abolish banking secrecy. Switzerland refused and offered to impose a withholding tax on interest income instead. The two...

Turmoil in financial markets is often accompanied by a significant decrease in market liquidity. Here, we investigate how such key risk measures as likelihood of insolvency, value at risk, and expected tail loss respond to bid-ask spreads that are likely to widen just when positions must be...

This paper analyzes how an investor who is convinced that he can quot;beat the marketquot; should behave when the equilibrium price process is endogenous. The investor's optimal portfolio is shown to consist of three components: (1) a tangency portfolio, (2) a hedge portfolio against changes in...

When information is costly, a seller may wish to prevent prospective buyers from acquiring information, for the cost of information acquisition is ultimately borne by the seller. A seller can achieve the desired prevention of information acquisition through posted-price selling, by offering...

A few recent papers have derived estimates of the representative agent's risk aversion by comparing the statistical density of asset returns and the state-price density. The implied risk aversion estimates obtained in these studies are puzzling, exhibiting (i) pronounced U-shaped patterns (a...

We investigate the suitability of securitization as an alternative to reinsurance for the purpose of transferring natural catastrophe risk. We characterize the conditions under which one or the other form of risk transfer dominates using a setting in which reinsurers and traders in financial...

Atypical employment contracts are either considered as traps that hinder permanent employment in the primary segment of the labour market or as stepping-stones leading to stable employment. Whereas the former interpretation appears to apply to Germany, our analysis of on-call contracts in the...
