Simulating the Impacts of Rural Social Cash Transfers and Farmer's Subsidies in Malawi and Ghana
A considerable body of experimental economics research examines the impacts of cash transfer programmes. In many developing countries, though, cash transfers are relatively minor compared to other transfer mechanisms in terms of their claim on public resources. In Malawi, fertilizer subsidies dwarf cash transfers, while next door in Zambia, the government pays farmers prices well above market levels for their maize. Yet no study to our knowledge has attempted to compare the full impact of social cash transfers and other kinds of transfers on rural incomes and welfare in low-income countries. (?)
A simulation impact evaluation of rural income transfers in Malawi and Ghana
We use a disaggregated rural economy-wide modelling framework to simulate and compare the impacts of an input subsidy, cash transfer, and output price support on production and welfare in rural Malawi and Ghana. Household groups in the models are defined by their eligibility for current transfers. Simulations are calibrated to official government spending. No intervention appears as unequivocally superior. The impacts and efficiency of each transfer mechanism are shaped by the structure of the economy, market conditions, and programme design.
The development of biological systematics : Antoine-Laurent de Jussieu, nature, and the natural system
A reevaluation of the history of biological systematics that discusses the formative years of the so-called natural system of classification in the eighteenth and nineteenth centuries. Shows how classifications came to be treated as conventions; systematic practice was not linked to clearly articulated theory; there was general confusion over the "shape" of nature; botany, elements of natural history, and systematics were conflated; and systematics took a position near the bottom of the hierarchy of sciences.
