In the Savannah region of West Africa, the highly variable rainfall and poor soils have been shown to di€erentially a€ect the yield potential of various crops. The paper applies a simple risk programming model to assess the e€ects of price and yield risk on the incomes of smallholder farmers in northern region of Coà te d'Ivoire. The analysis showed that by considering price and yield risks, it...

This paper tests the efficiency of insurance markets in the Pakistan Punjab by examining how crop choices are affected by the presence of price and yield risk. We estimate reduced-form and structural models of crop choices. Although we cannot reject the hypothesis that village members efficiently share risk among themselves, production choices are shown to depend on risk. Existing risk sharing ...

the aim of this study was to examine potato growers' perceptions of risk sources and risk management strategies and their risk management behavior. a survey research method was used in this study. the data originated from a sample of potato growers (n= 128) of ardabil province in the cropping year of 2013. the respondents were divided into two groups of less risk-averse (lra) and more risk-aver...

Spring wheat yields across the Canadian prairies are rising, however, a yield gap remains between average and potential which can be explored further under Prairie conditions. The high rates of nitrogen (N) fertilizer required for current high-yielding cultivars may increase lodging risk adding to this gap. objectives study were determine influence intensive management through N fertilization p...

OBJECTIVE To analyse the relation between tar and nicotine yield of cigarettes smoked in the recent past and the risk of myocardial infarction. DESIGN Multicentre case-control study conducted between September 1988 and June 1989. SETTING Over 80 coronary care units in various Italian regions. SUBJECTS 916 patients with acute myocardial infarction without history of ischaemic heart disease...

BACKGROUND There is variation in cardiac catheterization utilization across jurisdictions. Previous work from Alberta, Canada, showed no evidence of a plateau in the yield of high-risk disease at cardiac catheterization rates as high as 600 per 100,000 population suggesting that the optimal rate is higher. This work aims 1) To determine if a previously demonstrated linear relationship between t...

Modern methods of quantitative risk analysis, specifically value-at-risk and expected shortfall approach, provide comprehensive and coherent risk evaluation throughout entire distribution of outcomes and can take agricultural business from the realm of uncertainty to specific, quantified risks. Monte Carlo simulation with autocorrelation of standard deviation shows the best results in risk mode...
