This paper examines the small world hypothesis. The first part of the paper presents empirical evidence on the evolution of a particular world: the world of journal publishing economists during the period 1970-2000. We find that in the 1970's the world of economics was a collection of islands....

In this paper we want to analyze the internal divisional structure within an organi-zation in the framework of incomplete contract theory. We use the framework of Aghionand Tirole (1997) and define the managerial control structure as sequence of search.A key feature of this paper which...

We model a firm in an institutional market setting, consisting of a production technology and its governance. The governance consists of a hierarchical firm structure, a cost efficiency parameter,and an internal pay system. The depth of the firm is determined by profit maximization under the...

This paper shows that the presence of conditional staging in R&D (Research & Development) has a critical impact on portfolio risk, and changes diversification arguments when a portfolio is constructed. When R&D projects exhibit option-like characteristics, correlation between projects plays a...

Consider using the simple moving average (MA) rule of Gartley (1935) to determine when to buy stocks, and when to sell them and switch to the risk-free rate. In comparison, how might the performance be affected if the frequency is changed to the use of MA calculations? The empirical results show...

Cyclicality in the losses of bank loans is important for bank risk management. Because loans have a different risk profile than bonds, evidence of cyclicality in bond losses need not apply to loans. Based on unique data we show that the default rate and loss given default of bank loans share a...

Little empirical evidence provides insight in person-oriented drivers of business survival and success of small business owners. In this paper I perform a duration analysis of business survival amongst young white (selfemployed) small business owners in the U.S. Compulsory exits are...

In this paper we provide an analysis of the process of creative destruction across 24 countries and 2-digit industries over the past decade. We rely on a newly assembled dataset that draws from different micro data sources (business registers, census, or representative enterprise surveys). The...

Risk is at the center of many policy decisions in companies, governments and other institutions. The risk of road fatalities concerns local governments in planning counter- measures, the risk and severity of counterparty default concerns bank risk managers on a daily basis and the risk of...
