My research is primarily at the intersection of applied micro-economic analysis and economic geography and concentrates on the performance, location and spatial organization of firms in the following fields: - R&D, innovation, and technology adoption in geographic space - Spatial dimensions of outsourcing - Transport infrastructure and accessibility in the spatial economy

Holl, Adelheid. 2016. "Highways and productivity in manufacturing firms', Journal of Urban Economics, 93: 131-151.
Abstract: Using a geo-coded micro-level panel dataset for Spanish manufacturing firms, I estimate the effect of access to highways on firm-level productivity. To identify the causal effect of highways, I have relied on different fixed-effects specifications, instrumental variables and controls for geography, geology and history. Since highways also attract economic activity, leading to local density increases, which in turn could affect productivity through agglomeration benefits, I also present estimations that control for local employment densities. The results show that highways raise firm-level productivity directly and beyond the effect of density. Additional results show that highway benefits are unevenly distributed across sectors and space.
Adelheid and Ruth Rama (2014) Foreign subsidiaries and technology sourcing in Spain, Industry and Innovation, 21 (1): 43-64.
Abstract: Firms acquire external technological knowledge via different channels. In this paper, we compare the technology sourcing of foreign subsidiaries and domestic firms looking at domestic R&D outsourcing, international R&D outsourcing, domestic cooperation for innovation and international cooperation for innovation. We use data from the Spanish Technological Innovation Panel for the years 2005–2009 for 10,206 innovative firms operating in Spain. We apply a multivariate probit specification which allows for systematic correlations among the different choices. The results show that the different technology sourcing choices are interdependent and that foreign subsidiaries show a different pattern of external technology sourcing. Compared to affiliated domestic companies, foreign subsidiaries show a smaller propensity for external technology sourcing via R&D outsourcing from independent firms in the host country, for international R&D outsourcing and for international cooperation for innovation. In contrast, foreign subsidiaries show a greater propensity for domestic cooperation for innovation. However, foreign subsidiaries are not a homogenous group in this respect.
Holl, Adelheid. 2012. “Market potential and firm-level productivity in Spain” Journal of Economic Geography, 12 (6): 1191–1215.
Abstract: The literature has documented a large degree of heterogeneity across firms in terms of productivity. In this article, I focus on market potential as a source of differences in productivity across Spanish manufacturing firms. Market potential is conditioned by the existing transport infrastructure. Transport infrastructure investment improves accessibility to input and output markets and thus increases market potential. Market potential is measured by travel time through the real transport network and takes into account the immense improvements that have taken place in Spain over the last decades. The results show a significant positive effect of market potential on firm-level productivity, which is robust to various estimation methods. This indicates an important mechanism of how road infrastructure improvements can generate wider economic impacts.
Albarran, Pedro, Raquel Carrasco and Adelheid Holl. 2013 “Domestic transport infrastructure and firms' export market participation” Small Business Economics, 40 (4): 879-898.
Abstract: Investment in transport infrastructure reduces the cost of distance and enables firms to establish contacts over larger distances. Using data from a panel of Spanish manufacturing firms and geographic information system techniques, this article studies the impact of domestic transport cost reductions on firms’ export market participation, taking into account the role of entry costs and other firm characteristics. We estimate dynamic probability models, controlling for the unobserved heterogeneity of firms and for the simultaneity of firms’ export and location decisions. Our results demonstrate a positive effect of domestic transport infrastructure improvements on small and medium-sized firms’ probability of exporting.
