In recent years, the possibility of increasing production of legumes, whose area of cultivation has decreased, is being considered. It has been influenced by the yield variability which adversely affected the profitability of these plants cultivation. This paper attempts to assess the risk in...

The paper presents an analysis of wheat yields variability in the voivodeships of Poland. The main aim of the study was to find out what are the statistical relationships between the wheat yield variability and the following factors: arable area, size of wheat production area, share of arable...

An increased volatility of agricultural products' prices, observed in recent years, has caused a greater exposure of market participants to the market risk. The main goal of this article is to estimate the volatility of price returns in the grain legumes grown in Poland and the ground soybean...

Observed increased volatility of world commodity prices causes an increase of risk exposure. Thus market participants can not achieve the desired value of their goal function. The aim of this research was an assessment of wheat prices volatility in selected EU member states. Results of the...

The paper presents an analysis of the wheat yields variability in voivodeships of Poland. The main aim of the study is to present several possible indicators for the crop variability in the context of production risk. It is found that ignoring the long-term yield trends leads to a serious...

Our study focuses on modeling Colorado potato beetle (CPB) outbreaks and damage caused in Maine. The approach is to evaluate CPB outbreak frequency in a spatio-temporal framework. A block bootstrapping method with has been used to evaluate the CPB damage on a experimental field of potatoes. With...

This study examines formation and adaptation of reference prices by Manitoban grain producers. Research shows that preferences are reference‐dependent and marketing decisions are affected by reference prices. Results suggest that Manitoban producers’ reference prices are formed primarily by...
