|January 2020||Technological Transitions with Skill Heterogeneity Across Generations|
with Rodrigo Adão, Martin Beraja: w26625
Why are some technological transitions particularly unequal and slow to play out? We develop a theory to study transitions after technological innovations driven by worker reallocation within a generation and changes in the skill distribution across generations. The economy’s transitional dynamics have a representation as a q-theory of skill investment. We exploit this in two ways. First, to show that technology-skill specificity and the cost of skill investment determine how unequal and slow transitions are by affecting the two adjustment margins in the theory. Second, to connect these determinants to measurable, short-horizon changes in labor market outcomes within and between generations. We then empirically analyze the adjustment to recent cognitive-biased innovations in developed econ...
|June 2019||International Comovement in the Global Production Network|
with Zhen Huo, Andrei A. Levchenko: w25978
This paper provides a general and unified framework to study the role of production networks in international GDP comovement. We first derive an additive decomposition of bilateral GDP comovement into components capturing shock transmission and shock correlation. We quantify this decomposition in a parsimonious multi-country, sector and factor network propagation model featuring a single composite supply shock, with data for 29 countries and up to 30 years. We find that the network transmission of shocks can only account for a minority of observed comovement under a range of standard values of structural elasticities. To assess the role of delayed propagation and intertemporal shocks– features absent in the standard static framework– we extend both the accounting decomposition and the mode...
|May 2019||Multinationals, Offshoring and the Decline of U.S. Manufacturing|
with Christoph E. Boehm, Aaron Flaaen: w25824
We provide new facts about the role of multinationals in the decline in U.S. manufacturing employment between 1993-2011, using a novel microdata panel with firm-level ownership and trade information. Multinational-owned establishments displayed lower employment growth than a narrow control group and accounted for 41% of the aggregate manufacturing employment decline. Further, newly multinational establishments in the U.S. experienced job losses, while their parent firms increased input imports from abroad. We develop a model that rationalizes this behavior and bound a key elasticity with our microdata. The estimates imply that a reduction in the costs of foreign sourcing leads firms to increase imports of intermediates and to reduce U.S. manufacturing employment. Our findings suggest that ...
|March 2015||TFP, News, and "Sentiments:" The International Transmission of Business Cycles|
with Andrei A. Levchenko: w21010
We propose a novel identification scheme for a non-technology business cycle shock, that we label "sentiment." This is a shock orthogonal to identified surprise and news TFP shocks that maximizes the short-run forecast error variance of an expectational variable, alternatively a GDP forecast or a consumer confidence index. We then estimate the international transmission of three identified shocks – surprise TFP, news of future TFP, and "sentiment" – from the US to Canada. The US sentiment shock produces a business cycle in the US, with output, hours, and consumption rising following a positive shock, and accounts for the bulk of short-run business cycle fluctuations in the US. The sentiment shock also has a significant impact on Canadian macro aggregates. In the short run, it is more impor...
