Commodity levies are used increasingly to fund producer collective goods such as research and promotion. In the present paper we examine theoretical relationships between producer and national benefits from levy-funded research, and consider the implications for the appropriate rates of matching...

Agricultural commodity taxes, called check-offs, are used to finance promotion, research, and other activities that can be regarded as industry collective goods. The collection of the check-offs and the programs they are used to fund have implications for the welfare of consumers, other...

This chapter first discusses what economists mean by "the incidence of agricultural policy" and why we care about it. Then it reviews models of the determinants of the differential incidence of different policies among interest groups such as suppliers of factors of production, consumers,...

Agricultural research has transformed agriculture and in doing so contributed to the transformation of economies. Economic issues arise because agricultural research is subject to various market failures, because the resulting innovations and technological changes have important economic...

Recent theoretical work suggests that government policies may in°uence the quality mix of a commodity. This paper provides empirical evidence of quality responses to government policies for wheat policy implemented in France. Analysis is conducted using a detailed data set that includes the...

We use newly constructed state-specific data to explore the implications of common modeling choices for measures of research returns. Our results indicate that state-to-state spillover effects are important, that the research and development lag is longer than many studies have allowed, and that...

Aconventional assumption of product homogeneity when the commodity of interest is actually heterogeneous will lead to errors in an analysis of the incidence of policies, such as taxes. In this article, an equilibrium displacement model is used to derive analytical solutions for price, quantity,...
