|July 2018||How Do Firms Build Market Share?|
with Anthony Priolo: w24794
The question of how firms build market share matters for firm dynamics, business cycles, international trade, and industrial organization. Using Nielsen Retail Scanner data for the United States, we document that in the consumer food industry, brands experience substantial growth in market share in the first four years after successful entry into a regional market. However, markups are flat with respect to brand tenure. This finding is at odds with a large literature on customer markets which argues that firms acquire customers by temporarily offering low markups, and later raise markups once customers are locked in. However, it is consistent with a literature which emphasizes the importance of marketing and advertising activities for building market share.

with Stefanie Haller, Yaniv Yedid-Levi: w21935
We document how export quantities and prices evolve after entry to a market. Controlling for marginal cost, and taking account of selection on idiosyncratic demand, there are economically and statistically significant dynamics of quantities, but no dynamics of prices. To match these facts, we estimate a model where firms invest in customer base through non-price actions (e.g. marketing and advertising), and learn gradually about their idiosyncratic demand. The model matches quantity, price and exit moments. Parameter estimates imply costs of adjusting investment in customer base, and slow learning about demand, both of which generate sluggish responses of sales to shocks.
|March 2014||Exporters and Shocks: Dissecting the International Elasticity Puzzle|
with Stefanie Haller: w19968
We use micro data for Ireland to estimate how export participation and the export revenue of incumbent exporters respond to tariffs and real exchange rates. Both participation and revenue, but especially revenue, are more responsive to tariffs than to real exchange rates. Our estimates translate into an elasticity of aggregate exports with respect to tariffs of between -3.8 and -5.4, and with respect to real exchange rates of between 0.45 and 0.6, consistent with estimates in the literature based on aggregate data. We argue that forward-looking investment in customer base combined with the fact that tariffs are much more predictable than real exchange rates can explain why export revenue responds so much more to tariffs.

|July 2004||Specialization, Factor Accumulation and Development|
with Juan Carlos Hallak: w10638
We estimate the effect of factor proportions on the pattern of manufacturing specialization in a cross-section of OECD countries, taking into account that factor accumulation responds to productivity. We show that the failure to control for productivity differences produces biased estimates. Our model explains 2/3 of the observed differences in the pattern of specialization between the poorest and richest OECD countries. However, because factor proportions and the pattern of specialization co-move in the development process, their strong empirical relationship is not sufficient to determine whether specialization is driven by factor proportions, or by other mechanisms also correlated with level of development.
