Traffic accidents with wild boar have increased rapidly over the last years in Sweden. This paper calculates and predicts costs of current and future accidents, totally and for different Swedish counties, based on estimates of wild boar populations. A logistic population model is assumed, and...

Profits from violating the quota, charge and permit market systems are compared. The results indicate that, for a given permit price, the violation profits of the charge and permit market systems are the same and exceed the profits from violating a quota system if the optimal use of inputs in a...

In this paper, wind data obtained from the Egyptian Meteorological Authority are used to assess monthly and annual wind power and wind energy. The study is based on data from 15 anemometer meteorological stations, distributed all over Egypt and covering a period ranging from 1973 to 1994. For...

EU policies focus ever more on rural development initiatives. The horse sector provides some opportunities. An I/O model is used to examine the aggregate effects of the horse sector on Swedish agriculture. The maximal potential of the sector accounts for around 12% of the total contribution to...

Optimal hedging strategies are analyzed for a cooperative operating a price pooling system in the presence of price and quantity risk. A three-period model, accounting for default risk and storage, is developed. Hedging allows the cooperative to increase the pool price offered to farmers by 2.8...

Many states have farm record associations which collect individual farm data. This data are used for research, extension, and teaching purposes. However, since membership in the associations is voluntary, the question arises whether the members are representative of the population of all farmers...

Off-farm work improves and reduces the riskiness of household income. Theoretical analyses reveal that the level and riskiness of off-farm income affect demand for farm/nonfarm investments. A two-limit Tobit model is estimated using ARMS data for 1996-2003. The impact on investment behaviour is...

The economic value of the innovation robotic milking systems (AMS) is examined for Swedish dairy operations. A mixed integer mathematical programming model, considering crops, calving distribution, seasonality and capacity constraints of the AMS system, is developed. The marginal value of...
