This paper investigates the determinants of vertical integration. We first derive a number of predictions regarding the relationship between technology intensity and vertical integration from a simple model with nancial imperfections andincomplete contracts. Then, we investigate these...

We study properties of structured financial products optimizing a utility functional of a customer. The conventional method may have the disadvantage that the a priori restriction to a certain number of assets could make it impossible to find the optimal portfolio. So instead of optimizing the...

We introduce new quantile estimators with adaptive importance sampling. The adaptive estimators are based on weighted samples that are neither independent nor identically distributed. Using the law of iterated logarithm for martingales, we prove the convergence of the adaptive quantile...

The evaluation of the likelihood function of the stochastic conditional duration model requires to compute an integral that has the dimension of the sample size. We apply the efficient importance sampling method for computing this integral. We compare EIS-based ML estimation with QML estimation...

This paper sheds light on the influence of exchange rate volatility on foreign direct investment (FDI), both at the theoretical and the empirical level. The novelty of the empirical analysis, which is based on a panel of 27 OECD countries over the period 1982-2002, is to provide evidence of a...
