    In this paper, we analyze the impact of transportation infrastructure quantity and quality on regional economic production. We exploit an extensive panel dataset on the German county level (N=401), expressing the capital value and condition of highways between 2007 and 2016, to estimate a spatially extended translog production function. The spatial specification uses SLX and SDEM models, with various linear and nonlinear variants estimated using FGLS and GMM estimators accounting for endogeneity. We find, in line with existing research, a positive impact of the quantity of transport infrastructure both locally and supra-regionally. We furthermore provide evidence for the claim that insufficient maintenance and low infrastructure conditions significantly slow economic growth through a negative correlation between GDP and the quality grade of highways. A more detailed analysis, distinguishing different types of highways and constructions, confirms these findings and underlines the importance of the Bundesstraßen network as compared to the Autobahn system. The estimated impact of the quality of bridges is rather ambiguous and requires further research to achieve a better understanding.

    As research indicates a gap between complex scientific measures of accessibility and simpler proxies used by firms, this paper analyses the impact of several market access indicators on the location decision of firms. It compares the role of inter- and intra-industry agglomeration as proxies of access with a newly developed gravity-based indicator incorporating transport distances and industry relations. The estimation results of a nested mixed multinomial logit model, based on a sample of 110,083 German firms, provide evidence that agglomeration effects play an essential role in firms' location choice, whereas the complex market access measure does not have a significant impact. This outcome holds true for large as well as small and medium sized enterprises and is confirmed in several robustness checks. Thus, the paper provides guidance to further research on companies' location decisions, highlighting that access indicators should be chosen specifically for the scientific context, as well as to firms to make more efficient location choices from the perspective of market access.

    This paper deals with the data generation process implemented for an analysis of the impact of the 9-Euro ticket on mode choice. We discuss the assumptions made and procedures used to process a raw dataset that is based on GPS traces of individuals’ movements and on survey data into the choice-set for a discrete choice model. Several steps of cleaning and merging are described in order to a) obtain a reliable dataset; b) define available modal alternatives with attributes such as distance, duration, and costs; and c) impute the travel purpose for each movement to form. Our main contribution is to show that a systematic analysis of the sample obtained at different stages of data processing is important to make sure that the final sample is unbiased. Furthermore, we contribute by analysing the difference between observed travel time and travel time calculated by routing tools such as Google Maps. We show that the often- employed approach of estimating RP based choice models on the basis of observed travel times for the chosen mode of transport but calculated travel times for the non-chosen alternatives can introduce a structural bias into the sample.
