This paper suggests a factor model for carry trade strategies wherethe regression coeffcients are allowed to depend on market volatility and liquid-ity. Empirical results on daily data from 1995 to 2008 show that a typical carrytrade strategy has much higher exposure to the stock market and also...

The persistence of financial instability calls into question the adequacy of the current regulatory regime. Acritical review of the three pillars at the core of current financial regulation exposes some structural flaws.[...]

The recent real estate bubble was fuelled by non-risk adjusted lending policies, low interest rates and complex finance vehicles. Mortgage-backed securities (MBS) played a crucial role in the crisis. These vehicles were praised as liquid capital market instruments that allowed mortgage lenders...

Market frictions inhibit perfect replication of property derivatives and dene the property spreadas a price measure in the incomplete real estate market. We identify transaction costs, transactiontime and short sale constraints as the main frictions in this market. Based on these frictions,...

A credit risk model for determining aggregated portfolio losses is suggested.Beside the common macrostructural dependencies between assetand recovery value, we incorporate possible inter-rm relations among theobligors of the portfolio. Through this channel we also establish relateddefault...

This paper addresses the issue of intergenerational and internationalsharing of longevity and growth risks. Current research on worldwidedemographic changes highlights the importance of longevity risk on financialmarkets and the need to devise optimal hedging vehicles. We present a...

Let S be an Rd-valued semimartingale and ( n) a sequence of C-valued inte-grands, i.e., predictable, S-integrable processes taking values in some given closedset C(!, t) ⊆ Rd which may depend on the state ! and time t in a predictable way.Suppose that the stochastic integrals ( n · S)...

It is well known from anecdotal, survey and econometric evidence that the relationshipbetween the exchange rate and macro fundamentals is highly unstable. Thiscould be explained when structural parameters are known and very volatile, neitherof which seems plausible. Instead we argue that large...
