NBER Working Papers by Thomas Chaney

We generalize Krugman's (1979) 'new trade' model by allowing for an explicit production chain in which a range of tasks is performed sequentially by a number of specialized teams. We demonstrate that an increase in market size induces a deeper division of labor among these teams which leads to an increase in firm productivity. The paper can be thought of as a formalization of Smith's (1776) famous theorem that the division of labor is limited by the extent of the market. It also sheds light on how market size differences can limit the scope for international technology transfers.

I build a simple dynamic model of the formation of an international social network of importers and exporters. Firms can only export into markets in which they have a contact. They acquire new contacts both at random, and via their network of existing contacts. This model explains (i) the cross-sectional distribution of the number of foreign markets accessed by individual exporters, (ii) the cross-sectional geographic distribution of foreign contacts, and (iii) the dynamics of firm level exports. I show that the firm level dynamics of trade can explain the observed cross section of firm level exports. All theoretical predictions are supported by the data.

What is the impact of real estate prices on corporate investment? In the presence of financing frictions, firms use pledgeable assets as collateral to finance new projects. Through this collateral channel, shocks to the value of real estate can have a large impact on aggregate investment. Over the 1993-2007 period, the representative U.S. corporation invests 6 cents out of each additional dollar of collateral. To compute this sensitivity, we use local variations in real estate prices as shocks to the collateral value of firms that own real estate. We address the endogeneity of local real estate prices using the interaction of interest rates and local constraints on land supply as an instrument. We address the endogeneity of the decision to own land (1) by controlling for observable determi...
