This paper is intended as a guide to building insurance risk (loss) models. A typical model for insurance risk, the so-called collective risk model, treats the aggregate loss as having a compound distribution with two main components: one characterizing the arrival of claims and another...

Beyond dimension two: A test for higher-order tail risk

Bormann, Carsten; Schienle, Melanie; Schaumburg, Julia - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2014

test to detect when tail dependence is truly high{dimensional and bivariate simplications would produce misleading results …. This occurs when a signicant portion of the multivariate dependence structure in the tails is of higher dimension than two …. Our test statistic is based on a decomposition of the stable tail dependence function, which is standard in extreme value …

Copula-Based Dynamic Conditional Correlation Multiplicative Error Processes

Bodnar, Taras; Hautsch, Nikolaus - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2012

We introduce a copula-based dynamic model for multivariate processes of (non-negative) high-frequency trading variables revealing time-varying conditional variances and correlations. Modeling the variables’ conditional mean processes using a multiplicative error model we map the resulting...

Monitoring, Information Technology and the Labor Share

Schneider, Dorothee - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2011

This paper assesses empirically the hypotheses by Bental and Demougin (2010) that innovations in ICT (Information and Communication Technology) reduce the labor share in OECD countries by improving the monitoring technology. In a first step, I show that data trends for the labor share, wages in...

Dynamic Activity Analysis Model Based Win-Win Development Forecasting Under the Environmental Regulation in China

Chen, Shiyi; Härdle, Wolfgang Karl - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2012

Porter Hypothesis states that environmental regulation may lead to win-win opportunities, that is, improve the productivity and reduce the undesirable output simultaneously. Based on directional distance function, this paper proposes a novel dynamic activity analysis model to forecast the...

Institutions, Bargaining Power and Labor Shares

Bental, Benjamin; Demougin, Dominique - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2006

We use a static framework characterized by both moral hazard and holdup problems. In the model the optimal allocation of bargaining power balances these frictions. We examine the impact of improved monitoring on that optimal allocation and its impact upon effort, investment, profits and rents....

Product policy and the East-West productivity gap

Görzig, Bernd; Gornig, Martin; Voshage, Ramona; … - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2009

After 20 years of transition from an economy integrated in an exchange scheme of planned economies towards an open market economy based on the ideas of competition, we ask whether East German firms succeeded in finding their place in the international division of labour. We concentrate on the...

Solow Residuals without Capital Stocks

Burda, Michael C.; Severgnini, Battista - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2008

For more than fifty years, the Solow decomposition (Solow 1957) has served as the standard measurement of total factor productivity (TFP) growth in economics and management, yet little is known about its precision, especially when the capital stock is poorly measured. Using synthetic data...

TFP Growth in Old and New Europe

Burda, Michael C.; Severgnini, Battista - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2009

Using Solow-Tornqvist residuals as well as two alternative measurements, we present estimates of total factor productivity (TFP) growth in a sample of 30 European economies for the period 1994-2005. In most of Western Europe, we find a deceleration of TFP growth since 2000. However, the...
