|September 2017||How Wide Is the Firm Border?|
with Ali Hortaçsu, Mary Jialin Li, Chad Syverson: w23777
We examine the within- and across-firm shipment decisions of tens of thousands of goods-producing and distributing establishments. This allows us to quantify the normally unobservable forces that determine firm boundaries; which transactions are mediated by ownership control, as opposed to contracts or markets. We find firm boundaries to be an economically significant barrier to trade: having an additional vertically integrated establishment in a given destination zip code has the same effect on shipment volumes as a 40 percent reduction in distance. We then calibrate a multisector trade model to quantify the economy-wide implications of transacting across vs. within firm boundaries.
|April 2012||Why Do Firms Own Production Chains?|
with Ali Hortacsu, Chad Syverson: w18020
We use broad-based yet detailed data from the economy's goods-producing sectors to investigate firms' ownership of production chains. It does not appear that vertical ownership is primarily used to facilitate transfers of goods along the production chain, as is often presumed: Roughly one-half of upstream plants report no shipments to their firms' downstream units. We propose an alternative explanation for vertical ownership, namely that it promotes efficient intra-firm transfers of intangible inputs. We show evidence consistent with this hypothesis, including the fact that upon a change of ownership, an acquired plant begins to resemble the acquiring firm along multiple dimensions.
