The Modern Wholesaler: Global Sourcing, Domestic Distribution, and Scale Economies - April 2017
(Job Market Paper)
Wholesale trading firms facilitate nearly half of all intermediate good transactions in the United States and distribute large quantities of imported varieties, but are rarely studied due to the scarcity of data and the difficulty in modeling their interactions with the rest of the economy. Using a comprehensive dataset to study the effect of wholesaler intermediaries on downstream producers, I construct and estimate a multi-stage model of downstream demand and wholesaler market entry, with wholesalers imperfectly competing in linked geographic markets. Counterfactual analysis shows that despite increases in wholesaler market power, intermediated international trade has two benefits for buyers: first, through buyers' valuation of globally sourced products, and second, through the passed-through benefits of wholesaler economies of scale. The combined benefits of intermediated international trade in 2007 account for a $340 billion yearly increase in buyer surplus.
The Incidence of Carbon Taxes in U.S. Manufacturing: Lessons from Energy Cost Pass-Through - April 2017
(NBER Working Paper 22281)
This paper studies how increases in energy input costs for production are split between consumers and producers via changes in product prices (i.e., pass-through). We show that in markets characterized by imperfect competition, marginal cost pass-through, a demand elasticity, and a price-cost markup are sufficient to characterize the relative change in welfare between producers and consumers due to a change in input costs. We find that increases in energy prices lead to higher plant-level marginal costs and output prices but lower markups.
The Extensive Margin of Exporting Products: A Firm-level Analysis - December 2015 -
(AEJ: Macroeconomics - Revise and Resubmit)
We develop a general equilibrium model of multi-product firms in international trade to quantify market access costs at the level of firms, their products, and their export destinations. We estimate this framework with a simulated method of moments under rich demand and access cost shocks, using Brazilian firm-product export data. Our estimates quantify the relevance of market access costs and reveal large economies of scope that differ across export destinations. We evaluate a scenario where market access costs for an additional product are reduced to the level of those in nearby countries, generating welfare gains similar to eliminating current tariffs.
Minimum Wage and Retail Price Pass-through: Evidence and Estimates from Consumption Data - October 2016
While the vast majority of minimum wage research has focused on possible disemployment and labor market effects, this paper examines its effect on prices. Utilizing detailed transaction-level datasets, we find minimal pass-through of minimum wage changes onto retail and grocery prices. Estimates from other industries suggest that, aside from the restaurant and fast-food sectors, this low pass-through holds more generally.
Connecting Production and Distribution: Linking Manufacturing and Wholesaling Data - October 2016
The wholesale industry facilitates the trade of over 50% of domestic manufactured goods. However due to data limitations, there has been little research in the linkage between the manufacturing and wholesale trade sectors. I develop an algorithm to link North American Industry Classification System (NAICS) codes for manufactured goods with the NAICS wholesale sectors that trade these goods.
