A common question when analyzing supply chains is how much a change in input costs at one stage in the supply chain affect prices downstream. To address this question, research has been conducted that examines the extent that changes in prices are “passed-through.” Much of the pass-through...

Traditional measures of the benefits of technological change use producer prices. Consumer-oriented measures are more appropriate but they require knowledge of price impacts. They may diverge in the presence of distortions. This paper shows that in general equilibrium they are interrelated...

Economics theorists for years have considered the possibility that the direction of technical change is altered by changes in relative prices. Prices also have been identified as one of the determinants of technical change through innovation. This article extends the theory of the firm to cover...

This study examines the relative price of a standard market basket of food items and a market basket of healthier alternatives. Because people in low-income neighborhoods may have fewer grocery stores and transportation alternatives, the effects of store size and competition on the price of a...

The impacts of market reforms on prices volatility in developing countries are not well understood because analysts have not been able to predict the impacts. This study investigates whether the reforms have exacerbated the degree of spatial volatility of maize price in Tanzania using ARCH-M...

A censored demand system estimator is proposed by extending the sample selection model of Heckman. Censoring is governed by a selection mechanism which avoids the restricitve Tobit parameterization. Results of application to household consumption of beverages suggest the estimator produces...

This study uses revealed preferences of consumers to study the consumer benefits from soy milk. The study specifies and estimates structural demand and reduced form models of competition for different milk types using US supermarket scanner data. The introduction of soy milk is used to estimate...

Failure of integrability is shown to cause path-dependence of willingness-to-pay measures of welfare change. Using the linear expenditure system, effects of failure of integrability are negligible (substantial) for estimating income (price) elasticities. For single price changes, Hausman's...
