During financial crises equity portfolios have suffered large losses. Methodologies for portfolio selection taking into account the possibility of large losses have existed for decades but their economic value is not well established. This article investigates the economic value in reducing the probability of large losses in portfolio selection. We combine mean-variance analysis with semi-param...

Contagious bovine pleuropneumonia (CBPP) is a disease that causes high morbidity and mortality losses to cattle. The financial implications of these losses are of great significance to cattle owners. Control of CBPP is therefore important as a way to salvage the losses and increase the incomes of cattle owners. This study estimated the economic cost of CBPP and the benefits of its control in tw...

Aim: To develop a simple mathematical model to assess the losses due to peste des petits ruminants (PPR) in small ruminants in India. Materials and Methods: The study was based on cases and deaths in goats and sheep due to PPR from the average combined data on ovine/caprine as published by Government of India for the last 5 years (2008-2012). All possible direct and indirect losses due to the d...

the objective of this study was to consider economic consequence of delayed conception of milking cows in large dairy farms in iran. optimum open days and milk production at peak were assumed to be 110 days and 45 kg respectively. price of milk, feed, semen and hormones were calculated based on average prices of autumn, 2013. results of this study showed that increasing days in milk (dim) from ...

This article examines the economic consequences associated with the death of a child. The economic costs (funeral and medical expenses and productivity losses) of child death 6 months following the death were estimated based on 213 parents who had experienced the death of a child (usually unexpectedly and predominantly mothers). Findings suggest that productivity losses associated with child de...

Severe health risks caused by PM10 (particulate matter with an aerodynamic diameter ≤10 μm) pollution have induced inevitable economic losses and have rendered pressure on the sustainable development of society as a whole. In China, with the "Polluters Pay Principle", polluters should pay for the pollution they have caused, but how much they should pay remains an intractable problem for policy ...

This paper presents an assessment of normalised flood losses in Europe for the period 1970–2006. Normalisation provides an estimate of the losses that would occur if the floods from the past take place under current societal conditions. Economic losses from floods are the result of both societal and climatological factors. Failing to adjust for time-variant socio-economic factors produces loss ...

Disease acts as a negative influence on the livestock production system, thus setting off a cascading affect of low production, low income, and subsistent livelihood. The consequences of animal diseases in livestock can be complex and generally go well beyond the immediate effects on affected producers. These diseases have numerous impacts, including productivity losses for the livestock sector...
