Although discrete hours choice models have become the workhorse in labor supply analyses. Yet, they are often criticized for being a black box due to their numerous underlying modeling assumptions, with respect to, e.g., the functional form, unobserved error components or several exogeneity...

Profit taxes are widely acknowledged to influence the location of firms' headquarters. This paper sheds light on the role of aspects of labor taxation for the international location of headquarters. We construct a unique data set of effective labor taxes in 120 countries and use data on the...

The cloud computing model is a modern concept of computation that provides a number of benefits for its adopters. This online computing model has been widely used in the western world and accepted to have some business and economic impacts. This paper provides some basic knowledge about cloud...

This paper presents a theoretical model on firms' patenting decision in vertically differentiated markets. The model's prediction regarding patenting and rival's market entry decision are then tested empirically. We find that in industries which are characterized by easy-to-use knowledge...

The theoretical and empirical innovation literature stresses the importance of regional fac-tors and locational conditions for location choice of firms and their innovation success. Innovation activities are not equally distributed in space because agglomeration effects and specific regional...

In 2004, the German Social Health Insurance introduced a co-payment for the first doctor visit in a calendar quarter. I combine a structural model of health care demand and a difference-in-differences strategy to estimate the effect of that reform on the number of visits. In the model, the...

The fractional probit (or fractional logit) model is used when the outcome variable is a fractional response variable, i.e. a variable taking a value between zero and one. In case of excess zeros, the fractional probit model might not be the optimal modeling device since this model does not...

Using the microdata of the Michigan Survey of Consumers, we evaluate whether U.S. consumers form macroeconomic expectations consistent with different economic concepts. We observe that 50\% of consumers have expectations consistent with the Income Fisher equation, 46\% with the Taylor rule and...

The recent index proposed in Ellison & Glaeser (1997) is now well established as the preferred method for measuring localization of economic activity. We critically review this index and build on the McFadden’s Random Utility (Profit) Maximization framework to develop an alternative measure...

This research project ranks German regions with help of interregional migration data instead of gross domestic product, household incomes, unemployment or quality of life estimates. Therefore we estimate regional utility differentials for German states and planning regions following the approach...
