Am 24. März 2010 fand in Berlin ein gemeinsam vom Bundesministerium für Wirtschaft und Technologie und dem Bundesverband der Deutschen Luftfahrtindustrie veranstaltetes Technologieforum statt. Detlev Müller-Wiesner, Präsident der Deutschen Gesellschaft für Luft- und Raumfahrt, vertiefte in...

The chicken-and-egg problem between localized knowledge spillovers and thespatial concentration of inventive activities makes it difficult to identify how proximity affects knowledge spillovers. Using sudden changes in travel time following the introduction of new flight routes, we identify that...

We study whether, when, and how better connectivity through nonstop flights leads to positive innovation outcomes for firms in the global context. Using unique data of all flights emanating from 5,015 airports around the globe from 2005 to 2015 and exploiting a regression discontinuity...

This paper studies the causal relationship between proximity and knowledge diffusion by exploiting sudden changes in travel time following the introduction of new flight routes. We find that decreasing travel time between U.S. cities by 20% increases knowledge flow by 0.5%, which corresponds to...

The paper looks at the inclusion of international aviation in the EU emissions trading scheme from the perspective of innovation. It argues that the initiative of the European Union to subject international aviation to the scheme has functioned as a catalyst for green innovation in the sector....

Today, evolving technologies have enabled scientific breakthroughs in innovative wind turbine designs, including taller wind turbine towers and longer blades. These breakthroughs will enable utility-scale wind turbines to reach higher into the atmosphere, access stronger winds, and produce...

Railroads, roads, rivers, and airways are the most common modes of transportation for people and commodities. The cost of different ways of transportation varies according to distance, luxury, size, fragility, and other factors. When the following factors are accounted for, the vehicle might...

We analyze the spatial diffusion of laser-technology in Germany during the early phase of development, between 1960 and 2005. Research in this new technological field began in a few larger centers and then spread to other regions. In the early years, a large firm of the electronics industry...

We sketch a visionary strategy for Europe in which full employment is quickly regained by 2020, income inequality is reduced and the economies are more sustainable. We call this scenario "vibrant". It is contrasted with what would happen if present policies continue within the European Union...
