This paper presents evidence on the spatial distribution and effects of urban agglomeration on firm innovation. It uses a unique dataset that consistently defines city boundaries and identifies firms' innovation-related activities across 25 developing countries in Asia. We find firm innovation...

Using firm birth records and startup data matched with cities' characteristics, this paper analyzes nearly 300 prefecture-level cities to examine the role of human capital and market access in shaping the economic geography of innovation-driven entrepreneurship in China. We document strong...

Using a panel data model, we study the effects of regional and industry-level traits on new business formation (NBF) for 164 industries across 266 Chinese prefectures between 1998 and 2007. The objective is to provide empirical estimates on effects of prefecture traits on entry rates, and in...

As the differences between the regions are more pronounced than among the countries, NUTS 2 regions of the new members that joined the EU after 2000 are considered. Due to the presence of externalities between the regions, the Solow growth model using interregional externalities is used. This is...

We introduce the knowledge spillover equation on a network. We construct a tool to investigating the knowledge spillover in terms of network. The mean-filed asymptotic solution of the equation has the following characteristics: (1) the growth rate is common for all agents on the network...

This study examines the effect of agglomeration and localized knowledge spillover on reward-based crowdfunding outcomes in the United States. By examining art projects specifically, we can measure how creative projects benefit from agglomeration or clustering, measured by the proportion of...

This paper exploits time and geographic variation in the adoption of Special Economic Zones in India to assess the direct and spillover effects of the program. We combine geocoded firm-level data and geocoded SEZs using a concentric ring approach, thus creating a novel dataset of firms with...

Using longitudinal Swedish data, we document robust evidence of highly local spillovers between individuals in similar occupations. The results are consistent with the existence of knowledge spillovers between workers performing similar work tasks in the same city-district. We further...

The existing literature on cluster embeddedness largely neglects the impact of finance on the development of firms' network linkages. This is striking in so far that particularly venture capital is often referred to as "smart money" providing firms not only with funds but also with network...

What role do spillover effects play in firm resilience during crises? Using high-frequency data on over 7 million import transactions, we ask this question in the context of the large trade disruption faced by US importers in the months immediately following the initial COVID-19 shock. While US...
