Slotting fees are fixed charges paid by food manufacturers to retailers for access to the retail market. The practice is both increasingly common and increasingly controversial.

We employ a vertical differentiation model to examine the potential bias in pricing-to-market (PTM) results when using unit values aggregating differentiated products. Our results show that: i) false evidence of PTM (“pseudo PTM”) is always found when using unit values, whether the law of...

I examine the welfare implications of informative advertising in a differentiated product duopoly market. The analysis reconciles the apparently conflicting results in previous studies that find advertising to be undersupplied in homogeneous product markets and in differentiated markets with a...

This article is based on a socio-economic impact study of the introduction and adoption of tissue-culture (tc) technology in banana production in Kenya. It attempts to demonstrate that a prudent introduction and promotion of a new biotechnological innovation in farming can make a positive...

To improve the welfare of the rural poor and keep them in the countryside, the government has been spending 40% of the value of agricultural GDP on agricultural support services. But can investment make smallholder agriculture prosperous in such adverse conditions? This paper derives an answer...

The objective of this study is to analyze technical change and the role of research and development (R&D) spillovers in this process for the U.S. agricultural sector. This study is composed of both a theoretical and an empirical analysis. In the theoretical analysis, a quality innovation model...

This paper examines the effect of foreign intellectual property right (IPR) systems and the policies that comprise them on U.S. exports of biotechnology related agricultural input industries. Policy components include the extent of patent coverage across industry sectors, enforcement mechanisms,...

The paper considers the econometric modeling of technology adoption when crop choice is simultaneous. Bivariate probit is used to estimate a model of irrigation technology choice and land allocation using a unique field-level data set from California's Central Valley. Special attention is paid...
