Competitive tendering of local bus services in Germany has received increased attention. Employing Seemingly Unrelated Regression analyses, we observe that prices have regionally varying determinants; for example, while prices throughout most of the federal state of Hesse increase over time,...

Although government regulations on product warranties are common, few studies have empirically examined their effects on product demand. Using a natural experiment, we examine the effect of a newly introduced government warranty regulation in China's automobile market on product demand....

Subsidies are considered important means to facilitate the provision of public transit, yet the empirical evidence implies that they can have harming effects on costs and possibly also on operators' performance. This paper examines the impacts of deficit-balancing subsidies on the cost...

The current level of competition in European commercial passenger rail markets is low and empirical data on customer preferences in intramodal competition has hardly been available, yet. Our study raises the knowledge of competition in commercial passenger rail by exploring the determinants of...

In this paper I analyze GMM estimation when the sample is not a random draw from the population of interest. I exploit auxiliary information, in the form of moments from the population of interest, in order to compute weights that are proportional to the inverse probability of selection. The...
