The paper presents an econometric model of dynamic agricultural input demand functions that include research based technical change and autoregressive disturbances and fits the model to annual data for a set of state aggregates pooled over 1950-1982. The methodological approach is one of...

Most studies utilizing experimental auction mechanisms to elicit consumers’ willingness to pay are designed to avoid potential substitution or demand-curve effects that may influence bid prices. However, previous research and auction designs have not considered the potential impact on bid...

Consumers' willingness to pay for food products decreases when the food label indicates that a food product is produced with the aid of modern biotechnology. This bulletin presents empirical evidence on consumers' willingness to pay for biotech foods based on the presence or absence of labels...

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...

A price discrimination model is proposed to explain extraneous information provided by internet sales sites for agricultural inputs. Whether an informative site is offered depends on price discrimination potential, which depends on how much farmers reveal heterogeneity by internet behavior....

In this paper the current state of supply modelling in agriculture is reviewed. It is argued that (I) the stock of knowledge of elasticities is depreciating, (2) historical estimates are misleading because many phenomena are confounded in few parameters, (3) available data are not being...
