This paper investigates the role of horizontal and vertical market structures in pricing differentiated products. The conceptual model demonstrates how substitution and complementarity relationships between products and across vertical channels relate to market concentration and market size. The...

Use of soil amendments, including organic materials and mineral fertilizers, is highly recommended for the replenishment of soil nutrients, improved soil health and more efficient use of fertilizers in sub-Saharan Africa. Along with other constraints, underdeveloped markets are often cited as a...

This paper investigates the pricing and vertical organization of differentiated products under imperfect competition. In a multiproduct context, a Cournot model is used to examine how substitution/complementarity relationships among products and vertical structures can affect the exercise of...

We develop a semi-structural price vector autoregression to capture coffee price dynamics over various time horizons. The presence of the International Coffee Agreement is permitted to alter supply responses to price signals through yield and planting effects. In the short run, the ICA caused...

U S grain prices affect one another This study uses Haugh-Pierce chi-square tests, bivariate autoregressive models, and dynamic multipliers to measure the extent of these effects Rice prices exhibit very little reaction to changes in other grain prices However, other grain prices relate closely...

The paper considers an industry transforming primary commodities (farm products) into processed commodities (food products). It focuses on the allocation of embedded characteristics (carbohydrate, protein, etc.) both across space and among commodities. The approach generates a spatial...

This paper develops an economic and econometric analysis of demand dynamics, with an application to US aggregate data over the period 1948-2010. The model builds on duality and the benefit function, which provide strong linkages with the theory. The research involves the specification and...

This article analyzes the dynamic relationships among weekly prices of price byproducts, long gram rice, and corn, using causality tests and dynamic multipliers The authors use forecasts to evaluate the time series model rice byproducts prices may be influenced more by shifts 10 demand than 10...

This paper investigates bundle pricing under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product generalizations of the Herfindahl-Hirschmann index (GHHI)...

This article explores the issue of price and expenditure endogeneity in empirical demand analysis. The analysis focuses on the US carbonated soft drink market. We test the null hypothesis that price and expenditures are exogenous in the demand for carbonated soft drinks. Using an Almost Ideal...
