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...

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...

A model of the organization of the international wheat market is presented (a) to explain historical competitive behaviour in the market and (b) as a framework for analysing the likely effects of changes in market conditions on competitive behaviour. In the model the market is segmented into...

Productivity often increases in a part of an industry while remaining unchanged in the rest of the industry. In assessing the social gain from a productivity increase in a part of an industry producing a tradeable commodity it is necessary to consider the relationships between the part of the...

Placing a price on greenhouse gas emissions using an emissions tax or auctioning tradable permits provide the least cost government intervention to reduce pollution. Initial effects of the charge on pollution include an increase in the relative prices of greenhouse gas intensive products and...

A common observation is that measures of productivity growth are pro-cyclical, meaning they are higher (or grow faster) on average during periods of economic expansion than during periods of economic contraction. This study focuses on measurement errors related to capital inputs as an...

This study compares two panel data sets that measure capital input at the state-level in U.S. agriculture. Despite a number of similarities between the data sets, such as the composition of assets, aggregation procedures, and time frame, an examination of the final estimates of capital service...

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...

Hen quotas were virtually freely transferable within Victoria when they were first introduced in 1975. The 1980's have witnessed a series of changes to regulations over quota transfers. Initially these changes were components of a plan to phase out quotas but that is no longer on the policy...

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...
