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...

The paper investigates price dynamics under market liberalization, with a focus on the effects of lowering price floors. We analyze price dynamics by specifying and estimating a dynamic Tobit model under time-varying volatility, where the market price is censored by a government-set support...

In this paper, we present an econometric analysis for the effects of a price floor on price dynamics and price volatility. A price floor (implemented as a part of government pricing policy) provides a censoring mechanism for price determination. We specify and estimate a dynamic Tobit model...

A method was developed with time series models to test hypotheses about the relationship between market structure and spatial price dynamics. Long-run dynamic multipliers measuring the magnitude of lagged adjustments for spatial milled rice prices were calculated from the time series model and...

In a period of market liberalization and multilateral trade negotiations, price discrimination for commodities with distinct markets provides additional policy options to support farm income. While both the USA and Canada have implemented price discrimination policies in their domestic dairy...
