This paper reviews the empirical evidence of persistent levels of regional self-employment and new business formation and the effect this persistence has on development. It is argued that a regional culture of entrepreneurship plays an important role in explaining persistence of...

In the context of technological change, the influence of innovative entrants on incumbents is considered a major driving force. Using global patent data, we analyze this influence for the case of the transition from combustion engine vehicles towards alternative technology vehicles (ATVs)....

With global specialization and trade, countries make directly but also indirectly use of the environment via traded goods. Based on the theory of comparative advantages, the Heckscher-Ohlin-Vanek approach, we are using the Ecological Footprint as a broad measure of environmental use because its...

We assess the conjunctural impact of price insulating policies on spatial price transmission of maize, rice and wheat in Cameroon, Kenya and Tanzania in the period 2005-2015. We therefore separately estimate the impact of trade policies within two regimes of behaviour of the domestic price...

Can TV influence the entrepreneurial decisions of individuals? To identify causal effects, we utilize a quasi-natural experiment, namely that during the division of Germany after WWI into the capitalistic West Germany and the socialistic East Germany, West TV was exogenously available only in...

This paper illustrates the importance of consistency between the empirical measurement and the concept of variables in macroeconomic models. Since standard New Keynesian models do not account for demographic trends and sectoral shifts, I propose adjusting hours per capita used to estimate such...

We investigate the stability of cooperative relationships between inventors and consequences for the characteristics and patent productivity of the respective regional innovation systems (RIS). The empirical analysis is for nine German regions over a period of 15 years. We find a rather high...

This paper proposes a search strategy for photovoltaic patents which allows to distinguish the photovoltaic system into sub-trajectories. Identifying and analyzing sub-trajectories is of particular importance for understanding micro patterns of technological change. The proposed search strategy...

In first- and second-price private value auctions with sequential bidding, second movers may discover the first movers' bid. Equilibrium behavior in the first-price auction is mostly unaffected but there are multiple equilibria in the second- price auction. Consequently, comparative statics...

We analyze whether start-up rates in different industries systematically change with business cycle variables. We mostly find correlations that are consistent with coun- ter-cyclical influences of the business cycle on entries in both innovative and non-in- novative industries. Entries into the...
