Covid-19 Shocking Global Value Chains (with Peter Eppinger, Gabriel Felbermayr and Oliver Krebs). PDF
In early 2020, the disease Covid-19 caused a drastic lockdown of the Chinese economy. We use a quantitative trade model with input-output linkages to gauge the effects of this adverse supply shock in China on the global economy through international trade and global value chains (GVCs). We find moderate welfare losses in most countries outside of China, while a few countries even gain from the shock due to trade diversion. As a key methodological contribution, we quantify the role of GVCs (in contrast to final goods trade) in transmitting the shock. In a hypothetical world without GVCs, the welfare loss due to the Covid-19 shock in China is reduced by 40% in the median country. In several other countries, the effects are magnified or reversed for several countries. Had the U.S. unilaterally repatriated GVCs, the country would have incurred a substantial welfare loss while its exposure to the shock would have barely changed.
Contracting Institutions and Firm Integration Around the World (with Peter Eppinger). PDF (Online Appendix)
Firm integration is fundamentally shaped by contractual frictions. But do better contracting institutions, reducing these frictions, induce firms to be more or less deeply integrated? To address this question, this paper exploits unique micro data on ownership shares across half a million firm pairs worldwide, including domestic and cross-border ownership links. We uncover a new stylized fact: Firms choose higher ownership shares in subsidiaries located in countries with better contracting institutions. We develop a Property-Rights Theory of the multinational firm featuring partial ownership that rationalizes this pattern and guides our econometric analysis. The estimations demonstrate that better contracting institutions favor deeper integration, in particular in relationship-specific industries.
Cultural Distance, Firm Boundaries, and Global Sourcing (with Yuriy Gorodnichenko and Gerard Roland). PDF, featured in VoxEU
Casual observation suggests that cultural differences play an important role in business transactions, yet systematic evidence on this relationship is scarce. This paper provides a novel empirical investigation of the effect of cultural distance on multinational firms' decisions to integrate their cooperation partners into firm boundaries, rather than transact with independent companies at arm's-length. To guide our empirical analysis, we develop a simple theoretical model which suggests that (i) cultural distance between contracting parties decreases the relative attractiveness of integration, and (ii) this effect is mitigated in more capital-intensive industries. We test these predictions using extensive product-, industry-, and firm-level data. We find a robust negative effect of cultural distance on the relative attractiveness of integration. In line with our theoretical predictions, we also find that the effect of cultural distance on firm boundaries is less pronounced in more capital-intensive industries.
This paper provides a county-level investigation of the economically-motivated gun violence in the U.S. To guide our empirical analysis, we develop a simple theoretical model which suggests that firearm-related robberies in a given county increase with the number of illegal guns and decrease with social capital and police intensity. Using detailed FBI data from 1986-2014, we find empirical evidence for the role of illegal guns, social capital, and police intensity in line with our theoretical predictions. To investigate the causal effect of illegal guns, we exploit plausibly exogenous variation in illegal firearm supplies due to gun thefts in contiguous states.
A Tale of Two Property Rights: Knowledge, Physical Assets, and Multinational Firm Boundaries. Journal of International Economics 122, 2020.
The theory of multinational firm boundaries has been shaped by two major paradigms: an earlier one, emphasizing the role of integration in preventing the dissipation of knowledge, and a more recent one, stressing the role of firm boundaries in mitigating underinvestments into relationship-specific assets in the face of contractual incompleteness. This paper develops a novel model encompassing both approaches in a unifying framework. The model predicts that the attractiveness of integration increases in the importance of the parent firm's knowledge capital and decreases in the importance of the affiliate's physical capital in a joint production process. Furthermore, stronger intellectual property rights (IPR) protection in the affiliate's country is predicted to mitigate the effect of knowledge intensity on the attractiveness of integration. I test these hypotheses using unique panel data on more than 100,000 firm pairs worldwide. In line with the model's predictions, knowledge-intensive parent firms choose higher ownership shares in their affiliates, yet this relationship is less pronounced the stronger the IPR protection in the affiliate's country. In addition, higher physical capital intensity of the affiliate is associated with lower ownership shares. These findings are robust to controlling for unobserved heterogeneity across countries, industries, and firms, providing strong support for the unifying theory of multinational firm boundaries.
We develop a theoretical framework explaining firms’ offshoring decisions in the presence of uncertainty. Our model highlights the role of labor market institutions in shaping a firm’s ability to effectively react to future shocks, yielding a sharp prediction of the prevalence of offshoring in a given industry: The propensity of firms to source intermediate inputs from foreign rather than domestic suppliers decreases in the foreign country’s labor market rigidity, and this effect is particularly pronounced in industries with higher volatility. Combining industry-level data on the U.S. offshoring intensity with measures of labor market rigidity and industry volatility, we find empirical evidence strongly supportive of the model’s predictions.
Time is On My Side: Relational Contracts and Aggregate Welfare (with Michael Pflüger). Oxford Economic Papers 71(3), 709–732, 2019.
This paper develops a simple general equilibrium model which establishes a link between the patience of economic agents and the well-being of nations. We show that firms in long-term oriented countries can mitigate hold-up inefficiencies by engaging with their suppliers in relational contracting – informal agreements sustained by the value of future relationships. Our model predicts that countries with a higher level of patience will exhibit greater economic well-being and higher total factor productivity. We provide empirical evidence in line with the predictions of our theory.
Relational Contracts and Global Sourcing. Journal of International Economics 101, 123-147, 2016.
Relational contracts – informal agreements sustained by the value of future relationships – are integral parts of global production processes. This paper develops a repeated-game model of global sourcing in which final good producers decide whether to engage with their suppliers in relational contracting and whether to integrate a supplier into a firm’s boundaries or deal with the latter at arm’s-length. The model predicts that the relative prevalence of vertical integration increases in the long-term orientation of the headquarters’ and suppliers’ managers. It further suggests that the share of a foreign subsidiary owned by a final good producer increases in the headquarters’ long-term orientation. Combining industry-level data from the U.S. Census Bureau’s Related Party Trade database with measures for long-term orientation from Hofstede et al. (2010) and the World Management Survey, I find empirical evidence supportive of the positive link between the long-term orientation of cooperation parties and the relative prevalence of vertical integration. Using information on managerial composition of firms and ownership stakes from the Bureau van Dijk’s Orbis database, I find that firms led by long-term oriented managers own higher shares of their foreign subsidiaries.
Formal and Informal Contracting in Global Sourcing. In Kohler, W., Yalcin E. (eds.): Developments in Global Sourcing. Cambridge, MIT Press, 2018.
This paper introduces relational contracts into a standard framework of global sourcing with partial contractibility to study the joint impact of formal and informal contracting institutions on a multinational firm’s make-or-buy decision. The model suggests that both formal contractibility and relational contracting affect a firm’s internalization decision, yet not necessarily in the same direction. The likelihood of vertical integration increases in the prevalence of relational contracting and in the contractibility of suppliers’ inputs but decreases in the contractibility of headquarters’ activities. Combining data from the U.S. Census Bureau’s Related Party Trade database with proxies for formal and informal contracting, I find empirical evidence supportive of this model’s predictions.
