The paper presents a theory of optimal transparency in the nancial system when nancial institutions have short-term liabilities and are exposed to rollover risk. Our analysis indicates that transparency enhances the stability of the - nancial system during crises but may have a destabilizing...

We use a comparative approach to study the incentives provided by dierent types of compensation contracts, and their valuation by risk averse managers, in a fairly general setting. We show that concave contracts tend to provide more incentives to risk averse managers, while convex contracts tend...

We propose a new continuous-time principal-agent model to study the optimal timing of stock-based incentives, when the effects of managerial actions materialize with a lag and are only progressively understood by shareholders. On the one hand, early contingent compensation hedges the manager...

In a moral hazard setting with a performance additive in effort and a symmetrically distributed noise term, I show that compensation contracts which are convex in performance are suboptimal when the agent has mean-variance preferences. With step contracts, I show that sticks are more efficient...

It is established that the standard principal-agent model cannot explain the structure of commonly used CEO compensation contracts if CRRA preferences are postulated. However, we demonstrate that this model has potentially a high explanatory power with preferences with decreasing relative risk...

This paper presented a new technique for the simulation of the Greeks (i.e. price sensitivities to parameters), efficient for strongly discontinuous payoff options. The use of Malliavin calculus, by means of an integration by parts, enables to shift the differentiation operator from the payoff...

In this paper we compare overall as well as downside risk measures with respect to the criteria of first and second order stochastic dominance. While the downside risk measures, with the exception of tail conditional expectation, are consistent with first order stochastic dominance, overall risk...

We propose a rational theory of momentum and reversal based on delegated portfolio management. A competitive investor can invest through an index fund or an active fund run by a manager with unknown ability. Following a negative cashflow shock to assets held by the active fund, the investor...

  This paper uses data from the British Household Panel Survey to shed further light on the fall in spending at retirement (the “retirement-consumption puzzle”).  Comparing food spending for men retiring involuntarily early (through ill health or redundancy) with spending for those who...

This paper presents the Conditional Probability of Default (CoPoD) methodology for modelling the probabilites of loan defaults (PoD) by small and medium enterprises (SMEs) and unlisted firms as functions of identifiable macroeconomic and financial variables. The process of modelling PoDs...
