Volume 15, Issue 2 - Special Issue in Honor of Professor Pagoulatos

To commemorate and recognize four decades of research, teaching and mentoring by Professor Emilio Pagoulatos, we compiled a volume of articles in his honor. His legacy spans four U.S. universities and a second generation of scholars. This volume contains a sample of the extensive work he co-authored or influenced in the area of agricultural and food industrial organization.

This paper develops estimates of price elasticity of demand for a sample of U.S. food and tobacco manufacturing industries and tests a model explaining differences in interindustry elasticity. The empirical results are consistent with the hypothesis that demand elasticity is in part determined by the competitive behavior of firms in an industry. In particular, high advertising expenditures result in lower elasticities of demand. Other important variables influencing demand elasticity are industry concentration, the stage of production, the existence of protection from domestic and foreign entry, and the extent of new-product introduction in a particular market. ‘What makes monopoly possible is the efficiency of large-scale operation; what makes it worthwhile is the slope of the demand curve’ [Dorfman (1978, p. 153)].

This paper provides estimates of elasticities of substitution between domestic and imported goods for 40 4-digit S.I.C. food manufacturing industries and explains the inter-industry differences among these coefficients in terms of industry sectoral characteristics. The results show that there is a wide range of variation among such elasticities and that the intensity of each industry’s percentage of output sold to final consumers, foreign direct investment, expenditures on advertising and the existence of import quotas affect the degree of substitutability between domestic and foreign goods in the face of a relative price change.

Current trends in the structure of hog production in the U.S. are toward facilities that are not only larger, but also more likely to be specialized, carrying out only some of the vertically linked phases of production in the same facility. This paper investigates the cost efficiency incentives for these changes by estimating a multistage cost function for hog production. Data are from the Hog Production Practices and Costs portion of the USDA’s 2004 Agricultural Resource Management Survey.

This article investigates the substitution between online advertising (ONLA) and offline advertising (OFFLA) as well as the impact of adopting ONLA on the total cost of advertising. We estimate an advertising translog cost function at the product-brand level, using monthly observations between 2005 and 2011 for each of three industries: beer, ready-to-eat cereals, and carbonated soft drinks. Although in all three industries we find that traditional media (TV and print) advertisements are close substitutes, we also find that ONLA is a complement to, rather than a substitute for, both TV and print media advertising. This may be explained by ONLA’s targeting younger market segments and acting as a reinforcement of TV and print media advertising exposure. Further results show that the adoption of ONLA has lowered the cost of advertising for achieving a sales target and that its complementarity effect is weakening over time.

In this article, the reasons why developing countries trade fewer agricultural products than developed countries are analyzed. Based on earlier findings that low trade volume in the agricultural sector is due to high trade costs, the focus is on evaluating the extent to which bilateral trade costs in the agricultural sector differ among trading partners. Using a neo-Ricardian trade model, the results show that systematically, asymmetric bilateral trade costs and variation in the level of agricultural productivity across all countries in the sample, are the main barriers to developing countries’ agricultural exports. In addition, low-income countries face higher trade costs to export than do high-income countries.
