This paper investigates the relationship between labour migration and agricultural productivity in the Northern Province of Thailand. Drawing on maize production data from a household survey, we estimate a stochastic production function to evaluate the effects of migration, remittances and...

Burning of rice stubbles is widely practised in Punjab, India, due to a lack of suitable machinery to direct drill wheat into combine-harvested rice residues. Although burning is a rapid and cheap option, and allows quick turn around between crops, it has serious effects on human and animal...

Cooking oil is known as an essential commodity in Indonesia. Having such an important role, the Indonesian government often interfered the cooking oil market to assure its price remain low. To do so, the government uses a subsidy policy as one of its instruments. A dynamic duopoly model is...

Research into IPM technologies has been conducted by NSW DPI for over 20 years. Evaluating the returns from investment in specific research and development projects is an important component of the NSW DPI science and research program. An economic evaluation has been conducted of IPM in managing...

Sugarcane is an important industrial crop in South China, mainly grown in Guangdong, Guangxi, Yuennan and Fujian Provinces. State farms are important cane producers. They produce about one-tenth of the nation’s total cane. These sugar companies are integrated enterprises including farm and...

This study is motivated by the suggestion that the objectives of the AWB Ltd have changed since semi-privatisation of the Australian Wheat Board under the Wheat Marketing Act, 1989. Conceptualising this change of objectives as a shift from revenue maximization to profit maximization, this study...

The Multi-species RIM (Resistance and Integrated Management) model is used in this analysis to investigate the value of Roundup-Ready® canola in the simultaneous management of annual ryegrass (Lolium rigidum) and wild radish (Raphanus raphanistrum). It is likely that the transgenic canola...

Spatial diversity indicators may serve policymakers as they seek to manage crop genetic diversity and externalities associated with diffusion of some genetically modified crops. This paper adapts ecological indices of spatial diversity to area distributions of modern wheat varieties in...

The introduction of genetically modified (GM) crops raises several issues. This paper looks at incentives required to reduce problems of illegal and improper use of GM proprietary technology used in growing GM crops. A simple model of producer behaviour describes some key influences of a...
