Ahlfeldt, Gabriel M./Wolfgang Maennig: External Productivity and Utility Effects of City Airports. (Regional Studies, forthcoming)
Airports should not be located in densely populated areas. The authors use the example of Berlin’s three airports to demonstrate that the benefits of inner-city airports, arising from improved access for residents of surrounding areas, are more than compensated for by negative external effects. Residents in the proximity of inner-city airports experience severe noise pollution and significant price markdowns of real estate of approximately 5-6% per 10db increase in noise. The study confirms recent findings that only limited productivity and utility effects result from intra-urban access to inter-city transport hubs.
Ahlfeldt, Gabriel M./Nicolai Wendland: How Polycentric is a Monocentric City? Centers, spillovers and hysteresis. (Journal of Economic Geography)
Local agglomerations have become more and more important for location choice of businesses, as their productivity is increasingly determined by the proximity to other businesses. The distance to the city center per se has a limited causal effect, although typically correlated with economic density within a city. As a result, sub-centers have gained increasing importance. With complementary industrial sectors and good transport links, these sub-centers can attract new businesses and contribute to the overall economic growth of the city.
Ahlfeldt, Gabriel M.: If We Build it, Will They Pay? Predicting Property Price Effects of Transport Innovations. (ENVIRONMENT AND PLANNING A, forthcoming)
The response of real-estate markets to planned projects for transportation infrastructure can be predicted using a new, integrated urban and transport economics model.
Based on the example of the expansions of London’s Jubilee Line and Docklands Light Railway (DLR) in 1999, it is shown that actual prices, in average, adjusted one-to-one to the predictions. The model used can be applied to various transport modes and real-estate types.
Ahlfeldt, Gabriel M./Georgios Kavetsos: Form or Function? The Impact of New Football Stadia on Property Prices in London. (work in progress)
Prestigious sports facilities are increasingly among the most expensive development projects worldwide. Still, external benefits may exceed construction costs. Stadium Architecture, however, is central to positive spillover effects on the surrounding area. Public funding for large sports facilities should therefore be made conditional on a comprehensive urban design strategy, which can maximize these benefits. The authors demonstrate this using the example of two of the largest stadium projects of the last decade, the New Wembley and Emirates Stadia in London.

Ahlfeldt, Gabriel M./Wolfgang Maennig: Are Renters better Voters? A Spatial Analysis of Aircraft Noise Effects. (Revise and submit to Journal of Public Economics)
Evidence from the closure of Tempelhof Airport, a unique natural experiment, demonstrates that the value of residential properties increases by about 4% for every decibel decrease in noise.Even the announcement of an airport expansion or closure has an effect of property values. In the noise protection zones of Berlin Tempelhof, the announcement of the closure resulted in a positive adjustment of property values. In the case of the expansion announcement in Schönefeld, a negative adjustment was observed. In general, the strongest effects were observed for owner-occupied single and two-family homes. Furthermore it is evident from results in the Tempelhof-Volksentscheid 2008 that reductions of noise emissions were welcomed significantly more by homeowners as compared to renters.
Ahlfeldt, Gabriel M./Stephen J. Redding/Daniel M. Sturm/Nikolaus Wolf: The Economics of Density: Evidence from the Berlin Wall. (work in progress)
The division and reunification of Berlin has had a persistent effect on the structure of the city. For example, the City-West persists as a prominent center even after reunification. This can be attributed to the interplay of various agglomeration forces. The study uses a new urban economics model that examines location choice of households and businesses in light of mutual dependence.
Ahlfeldt, Gabriel M./Bastian Franke/Wolfgang Maennig: Terrorism and the Regional and Religious Risk Perception of Foreigners: The case of German Tourists. (work in progress)
German tourists react to unanticipated shocks, such as terrorist attacks, with an alteration of risk perception of specific tourist destinations (9/11 2001, Egypt 1997, Tunisia 2002, Morocco 2003 and Indonesia 2003). There terror attacks led to a reduction in German tourism in Islamic nations, which indicates a transmission mechanism driven by ethnic and religious proximity. Notably, German tourism in Islamic nations was temporarily replaced by increased travel to south-European countries.
Ahlfeldt, Gabriel M./Arne Feddersen: From Periphery to Core: Economic Adjustments to High Speed Rail. London School of Economics and Political Science & University of Hamburg. (work in progress)
High-speed (HS) systems can sustainably promote the economic activity of regions. HS Trains connect various economic actors and increase their access to regional markets. Thus, significant public investment in these systems can be justified. Using the example of the Cologne-Frankfurt track, the authors demonstrate an expansion of GDP by 0.25 % for every 1% of added market access.
Ahlfeldt, Gabriel M./Wolfgang Maennig/Tobias Osterheider: Regional effects of a global monetary policy: Evidence from the Euro-referenda in Denmark and Sweden. (work in progress)
The local economic structure has significant impact on the citizens´ attitudes towards a monetary union.
Danish and Swedish people in areas with dominant industrial sectors that would benefit from adoption of the Euro voted significantly more in favor. This includes interest insensitive sectors with high international integration (e.g. financial sector). The opposite is true for interest sensitive sectors with limited international integration (e.g. construction sector). This study is the first to test sectoral and regional effects of a common monetary policy (European Economic and Monetary Union) in light of voter preferences and by using spatial models. The authors are able to demonstrate that the expectations of personal costs ranked higher with increased distance from the center of European monetary policy (EZB) and with age of the voter (likely resulting from positive experiences with the existing monetary unit). The results are robust to unobserved spatial heterogeneity and not caused by widespread Euro-skepticism.
Ahlfeldt, Gabriel M./Nicolai Wendland: Spatial Determinants of CBD Emergence: A Micro-level Case Study on Berlin. (work in progress)
Households choose their place of residence increasingly independent of the location of the workplace. To optimize the emerging commuter patterns, promoters of urban development have developed strategies for a directed urban decentralization. In this study, the authors use the example of the Berlin City-West to suggest a process of directed urban concentration and demonstrate that the emergence of new economic sub-centers can be promoted by local transport hubs, which connect the surrounding area in addition to the existing city center.
