This paper aims to describe the calculation of environmental and health externalities caused by air pollutants, accidents and noise from different transport modes (road, rail, air) on the route Frankfurt-Milan. The investigation is part of the QUITS project (QUITS = Quality Indicators for...

The specification of parameters is a crucial task in the development of economic models. The objective of this paper is to improve the standard parameter specification of computable general equilibrium (CGE) models. On that account, we illustrate how Optimal Fingerprint Detection Methods (OFDM)...

Sensitivity analysis studies how the variation in the numerical output of a model can be quantitatively apportioned to different sources of variation in basic input parameters. Thus, it serves to examine the robustness of numerical results with respect to input parameters, which is a...

This paper shows that earnings losses after unemployment increase with age. First, older employees start out with relatively high earnings in comparison to employees without employment interruptions several years before the non-employment spell. This earnings advantage turns into a strong...

Using data from the German Socio-Economic Panel for the years 2000 to 2006 we analyze the determinants and labor market effects of educational dropout. In addition to classical variables like family background and occupation, we examine noncognitive skills and Internet use. Noncognitive skills...

This paper provides firm-level evidence for the relationship between the age structure of the workforce and the adoption of new or significantly improved technologies in service sector firms. Furthermore, it closes a research gap by analyzing the joint impact of the age of the workforce and the...

This study tests for financial constraints on R&D investment and how they differ from capital investment. To identify constraints in the access to external capital, we employ a credit rating index. Our models show that internal constraints, measured by mark-ups, are more decisive for R&D than...

This paper examines return predictability when the investor is uncertain about the right state variables. A novel feature of the model averaging approach used in this paper is to account for finite-sample bias of the coefficients in the predictive regressions. Drawing on an extensive...
