Rating agencies state that they take a rating action only when it is unlikely to be reversed shortly afterwards. Based on a formal representation of the rating process, I show that such a policy provides a good explanation for the empirical evidence: Rating changes occur relatively seldom,...

In a series of recent papers, Mark Roe and Lucian Bebchuk have developed further the concept of path dependence, combined it with concepts of evolution and used it to challenge the wide-spread view that the corporate governance systems of the major advanced economies are likely to converge...

Recent changes in accounting regulation for financial instruments (SFAS 133, IAS 39) have been heavily criticized by representatives from the banking industry. They argue for retaining a historical cost based mixed model where accounting for financial instruments depends on their designation to...

Estimation risk is known to have a huge impact on mean/variance (MV) optimized portfolios, which is one of the primary reasons to make standard Markowitz optimization unfeasible in practice. Several approaches to incorporate estimation risk into portfolio selection are suggested in the earlier...

This study contributes to the valuation of employee stock options (ESO) in two ways: First, a new pricing model is presented, admitting a major part of calculations to be solved in closed form. Designed with a focus on good replication of empirics, the model fits with publicly observable...

The aim of this paper is to explore the patterns of trade duration across regions and to identify its determinants. Using an extended Cox model, we evaluate the effects of country and product characteristics, as well as of trade cost variables on the duration of trade relationships from 96...

This paper analyzes the spatial interdependence of Free Trade Agreements (FTAs) in a cross-section framework using the Contagion Index proposed by Baldwin and Jaimovich (2010). A Bayesian heteroskedastic probit model is estimated, where a spatial lag is built based on the Contagion Index,...

In this paper we combine the tariff evasion analysis of Fisman and Wei (2004) with Rauch and Trindade's (2002) study of Chinese trade networks. Chinese networks are known to act as trade catalysts by enforcing contracts and providing market information. As tariff evasion occurs outside the law,...
