Networks and export performance of agri-food firms:New evidence linking micro and macro determinants
agribusiness export performance firm heterogeneity gravity equation Heckman model internationalisation networks
2016/11/11
The paper complements a new line of research that includes the firm heterogeneity in trade models. The central idea of this research is that only the largest and most efficient firms are capable of ex...
We specify and implement a test for the importance of network effects in determining the
establishments at which people work, using recently-constructed matched employer-employee data at the
establi...
Resident Networks and Firm Trade
Information Networks Trade Links Firm Behavior Information Networks Ethnicity Characteristics
2015/4/28
We demonstrate that simply by using the ethnic makeup surrounding a firm's location, we can predict, on average, which trade links are valuable for firms. Using customs and port authority data on the ...
The Architecture of Transaction Networks: A Comparative Analysis of Hierarchy in Two Sectors
Customer Value and Value Chain Market Transactions Networks Competitive Strategy Vertical Integration
2015/4/24
Many products are manufactured in networks of firms linked by transactions, but comparatively little is known about how or why such transaction networks differ. This paper investigates the transaction...
Liquidity in Credit Networks: A Little Trust Goes a Long Way
Liquidity Credit Networks Little Trust Goes a Long Way
2010/10/21
Credit networks represent a way of modeling trust between entities in a network. Nodes in the network print their own currency and trust each other for a certain amount of each other's currency. This...

Backbone of complex networks of corporations: The flow of control
Backbone complex networks of corporations
2010/10/29
We present a methodology to extract the backbone of complex networks based on the
weight and direction of links, as well as on nontopological properties of nodes. We show how
the methodology can be ...
