The correct modeling of default dependence is essential for the valuation of multiname credit derivatives. However for the pricing of synthetic CDOs a one-factor Gaussian copula model with constant and equal pairwise correlations, default intensities and recovery rates for all assets in the reference portfolio has become the standard market model. If this model were a reflection of market opini...

Some studies have provided evidence that dual class shares reduce firm market value. Other studies have shown that dual class shares are more common in countries where the proxies for private benefits of control are low. In this paper we explore whether the negative relation between firm market value and dual class shares can be explained by lower takeover probability. For family controlled fir...

Accordingly, the bank development index is proxied by the allocated credits to private sector, while a dummy variable has been defined as a proxy for credit market. To estimate the regressions, we have used data of...

This paper investigates the effect of Internet technology on how firms access export markets directly or via intermediaries. Empirical evidence suggests that technology diffusion is geographically localised, with knowledge spillovers from neighbouring adopters decaying quickly over short distances. To address the potential endogeneity of Internet adoption, I construct an instrument that capture...

Who Starts a Business and Who is Self-Employed in Germany Based on representative data, the German Micro-Census, we provide an overview of the development of self-employment and entrepreneurship in Germany between 1991 and 2010, the first two decades after reunification.

In this paper we use a panel of administrative data to determine the factors associated with primary care physician self-selection into different payment models in Ontario, Canada. We find that primary care physicians will self-select into payment models based on existing practice and individual characteristics. These patterns of self-selection largely follow a utility maximizing model of physi...

The paper analyzes the effect of incentives regulation, when the yardstick competition approach is supplemented with a performance tax on providers. In an application to prospective payments in health care in the U.S. and Japan, we show differential effects of value-based purchasing, when price-setting is related to benchmark values of quality measures or length-of-stay. The predictions of our ...
