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...

Generic advertising has been a widely-used marketing tool of many agricultural industries. The strategy has come under increasing scrutiny lately, especially by levy-paying producers who fund the advertising. Also, for many food products, supermarket chains have developed and advertised their...

An equilibrium displacement model of the world wool top industry is used to estimate the returns to the Australian wool industry from productivity improvements in farm production, in top making and in textile manufacturing. The returns to the industry from these different types of research and...

In general, reported rates of return to agricultural R&D are high, but questions have been raised about upward biases in the evidence. Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of...

The literature on measuring the size and distribution of returns to research has paid increasing attention of late to questions that require a multimarket framework. These questions include the distribution of benefits among stages of a multistage process or among factors of production (i.e. the...

Econometric studies of the effects of research on productivity have typically imposed arbitrary restrictions on the length and shape of the R&D on productivity and the estimated rate of return to research. This paper argues that the useful stock of public knowledge depreciates, if at all, only...

Transgenic crops are relatively new technologies being adopted rapidly in the United States and in a few other countries. The economic impacts of these technologies have, thus far, been estimated in a piecemeal fashion. The purpose of this study was to collect and characterize the economic...

In general, reported rates of return to agricultural R&D are high, but questions have been raised about upward biases in the evidence. Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of...
