Product Variety in the U.S. Yogurt Industry

Rossetti, Joseph Anthony

Abstract Details

2018, Doctor of Philosophy, Ohio State University, Economics.
The products offered in an industry determine the profits of firms and consumer welfare. In this paper, I estimate a model of product entry and exit in the U.S. yogurt industry from 2001-2011 using supermarket scanner data from the IRI Marketing Database. I use a two-step procedure. I first estimate yogurt industry demand and variable costs using the standard framework of Berry et al. (1995). In the second step, I estimate the fixed costs of offering a product. Estimation of the fixed cost is complicated because firms can offer any subset of the potential product lines in the industry, but I only observe in the sample a small number of the possible combinations of products. I apply the pairwise maximum score estimator of Fox (2007), which provides consistent estimates in settings with large choice sets. I use the first stage estimates to compute firms' expected variable profits from offering alternative sets of products and choose the fixed costs parameters to maximize the number of times the model predicts that the firms' observed choices were optimal. In a counterfactual analysis, I find that increases in market concentration do not increase the incentives to offer more unique products than the competitive industry offered and that the increased product variety is not enough to compensate consumers for the increases in prices.
