A dynamic ‘smooth transition’ Almost Ideal model is estimated for food consumption in the US. A Metropolis-Hastings algorithm is employed to map the posterior distributions and rejection sampling is used to evaluate and impose curvature restrictions at more than one point in the sample. The...

BACKGROUND. Farmers are faced with a wide range of pest management (PM) options which can be adopted in isolation or alongside complement or substitute strategies. This paper presents the results of a survey of UK cereal producers focusing on the character and diversity of PM strategies...

This paper examines technology adoption and integrated pest management strategies employed by UK farmers, using both parametric and nonparametric methods. We employ a unique survey data set collected from UK cereal farmers to assess the determinants of technology adoption in relation to pest...

Over the past 50 years, crop protection has relied heavily on synthetic chemical pesticides, but their availability is now declining as a result of new legislation and the evolution of resistance in pest populations. Therefore, alternative pest management tactics are needed. Biopesticides are...

The measurement of the impact of technical change has received significant attention within the economics literature. One popular method of quantifying this impact of technical change is the use of growth accounting index numbers. However, in a recent article Nelson and Pack (1999) criticise the...

This study represents the first application of Choice Experiments to the analysis of the monetary and non-pecuniary determinants of vocational choice and spatial labor supply. It identifies the determinants of individual’s choice of jobs and place of residence, and provides a better...

The cross-entropy approach is extended to the estimation of cointegrated equations. The entropy estimators for an appropriately constructed moment form, are asymptotically equivalent to Fully Modi�ed estimators since they converge to these estimates su¢ ciently quickly. The performance of the...

Models developed to investigate the impact of cotton subsidies have found that US support, by virtue of its absolute magnitude, is particularly damaging and responsible for most of the reduction in cotton-earning potential in developing countries. This has been used as an argument for reducing...

In this paper we examine the time series properties of nine non-renewable resources. In particular we are concerned with understanding the relationship between the number of structural breaks in the data and the nature of the resource price path, i.e. is it stationary or a random walk. To...

The relationship between calorie and nutrient (fat, protein, and carbohydrates) intake as a function of income is explored using data for 171 countries over two time periods 1990-1992 and 2003-2005. Three types of analysis are employed: i) nonparametric, ii) panel regressions, and iii) quantile...
