In this paper, the Schumpeterian growth model developed by Ertur and Koch (2011) that includes spatial interactions between units of observation working via R&D spillovers is presented in detail. The implications of this model and three additional growth models with and without spatial...

This paper assesses the robustness of the empirical results in Ertur and Koch (2007), who develop a model, which accounts for technological interdependence among countries through spatial externalities. The original version models interdependence via an interaction matrix based on geographic...

In a laboratory experiment, we investigate if groups consisting of two heterogeneous player types (with different marginal contribution costs) can increase their total contributions and payoffs in a threshold public goods game if transfer payments are possible among the players. We find that...

In dynamic resource allocation models, the non-existence of voting equilibria is a generic phenomenon due to the multi-dimensionality of the choice space even with agents heterogeneous only in their discount factors. Nevertheless, at each point of time there may exist a "median voter" whose...

In auction and mechanism design, Myerson's classical regularity condition is often too weak for a quantitative analysis of performance. For instance, ratios between revenue and welfare, or sales probabilities may vanish at the boundary of Myerson regularity. This paper introduces L-regularity as...

This paper uses a new tailor-made data set to investigate for the first time the links between innovation activities (measured by employees active in research and development) and the extensive margins of exports (number of destination countries; number of goods exported) for manufacturing...

Wettbewerbspolitisch stellt sich die Frage, ob im 5er-Oligopol mit Aral, Shell, Esso, Total und Jet Binnenwettbewerb fehlt und ob dieses Oligopol wirksam Außenseiterwettbewerb ausgesetzt ist. Nach neuartigen Daten für vier Metropolen aus 2014, die auf die Marktransparenzstelle zurückgehen,...

Empirical studies on the link between green investment and other business investment at the firm level either focus on innovation specific types of investment or fail to consider the simultaneity of investment decisions. The analysis to be presented here offers a broad focus on different types...

Crinò and Epifani (2012) report and discuss two empirical regularities they find in a representative sample of Italian manufacturing firms. First, there is a negative correlation between firms' productivity and their export share to low-income destinations. Second, there is a negative...

This paper proposes two new panel cointegrating rank tests which are robust to cross-sectional dependency. The dependence in the data generating process is modeled using unobserved common factors. The new tests are based on a metaanalytic approach, in which the p-values of the individual...
