This paper estimates a dynamic, structural model of entry and exit in an oligopolistic industry and uses it to quantify the determinants of market structure and long-run firm values for two U.S. service industries, dentists and chiropractors. Entry costs faced by potential entrants, fixed costs...

This book explores the challenges regarding risks and risk management related to the growing complexity of ICT solutions. The main argument of the book is that the complexity of ICT solutions has continued to grow throughout the history of ICT, and that it has now reached a level that goes...

Global business is affected by global terrorism and the two are intricately linked on many levels. This book is an eclectic and enlightening compendium of research that explores the interrelationships between the two. A companion to and expansion on the authors' previous books on the area,...

In general, the properties of the conditional distribution of multiple period returns do not follow easily from the one-period data generating process. This renders computation of Value-at-Risk and Expected Shortfall for multiple period returns a non-trivial task. In this paper we consider some...

In this note it is argued that the estimation error in Value-at-Risk predictors gives rise to underestimation of portfolio risk. We propose a simple correction and find in an empirical illustration that it is economically relevant.

In the estimation of risk measures such as Value at Risk and Expected shortfall relatively short estimation windows are typically used rendering the estimation error a possibly non-negligible component. In this paper we build upon previous results for the Value at Risk and discuss how the...
