This paper analyses investment strategies of three types of institutional investors pension funds, life insurers and non-life insurers over the period 1999-2005. We use balance sheet and cash flow data, including purchases and sales of equity, fixed income and real estate. We trace asset...

In this paper, we study the aggregated risk from dependent risk factors under the multivariate Extreme Value theory (EVT) framework. We consider the heavy-tailness of the risk factors as well a non-parametric tail dependence structure. This allows a large scope of models on the dependency. We...

Extreme losses are the major concern in risk management. The dependence between financial assets and the market portfolio changes under extremely adverse market conditions. We develop a measure of systematic tail risk, the tail regression beta , defined by an asset's sensitivity to large...

Despite various payment innovations, today, cash is still heavily used to pay for low-value purchases. This paper develops a simulation model to test whether standard implications of the theory on cash management and payment choices can explain the use of payment instruments by transaction size....

One popular view on the current strength of the US dollar is that the higher growth in the US compared to Europe has stimulated foreigners to buy American assets, thereby driving up the exchange rate. In this paper a modified portfolio balance model is presented, in which it is shown that the...

In this paper we study why, and when, and in what form, a satisficing strategy is a better bet for survival, than a strategy which uses the best available information in attempting to optimize the outcome. We prove that, under severe uncertainty, a robust-satisficing decision has a better...

The empirical evidence of heavy tails in stock return data is recognised by risk managers as an important factor in assessing the Value-at-Risk and risk profile of investment portfolios. Tail index estimation appears to be a tailor-made tool for estimating the extreme quantiles of heavy tailed...

We present a new method to examine financial contagion, defined as a sudden strengthening of shock transmission between financial markets. In particular, we develop a correlation-like measure of synchronicity between markets that is straightforward to implement while being insensitive to...

This paper studies the effects of verbal interventions by European cen-tral bankers on high-frequency euro-dollar exchange rates. We find that ECB verbal interventions have had only small and short-lived effects. Ver- bal interventions which are reported in news report headlines are more likely...
