An approach is developed to examine the impact of product characteristics on choice using a quantity-dependent hedonic model with retail panel data. Since panel data for individual products from retail settings can include a large number of zero sales, a modification of the zero-inflated Poisson (ZIP) regression model is proposed for estimation. Results for this model compare favorably to results for alternative hurdle and negative binomial models. An application of this methodology to restaurant wine sales produces useful results regarding sensory characteristics, price, and origin/varietal information.

Firms selling products overseas may do so in a wide variety of ways, such a s through trading companies, foreign distributors, brokers, direct sales, license arrangements, and foreign direct investment. Many firms employ a portfolio of arrangements for each of their products. Using a share equation model, we examine the factors influencing food processing cooperatives' foreign business arrangements. Particularly important are the cooperative's financial resources and structure, risk exposure and risk preferences, information resources, and product types. Compared to investor-owned firms, we find that cooperatives have distinct disadvantages in investing or selling directly abroad, although the disadvantages are tempered by some equalizing considerations.
