Any calls to move towards a centrally planned economy or autarky are strongly advised against, as this would only be to the detriment of food security in the Global South.

According to the current state of research, there is little supporting evidence that the recent increase in financial speculation has caused either a)of the price level, or (b) the price volatility in agricultural markets to rise. Rather, fundamental factors are responsible for this. Therefore, most papers are not in favor of, but against (c) erecting market barriers by regulation. Against this background, the public alarm, which claims that financial speculation has detrimental effects and should be forbidden, seems to be a false alarm. Those who are interested in fighting global hunger should take care of fundamental factors and take appropriate measures to keep supply in step with demand, which is likely to rise in the near future.

Traditionally, the international wheat market has been considered a good example of a market with perfect competition. Yet, several articles provide evidence of imperfect competition and price discrimination in the wheat trade. However, these studies focused on traditional high-quality wheat exporters such as Canada and the United States. In contrast, this article investigates whether Russian wheat exporters exercise market power in eight selected importing countries using the residual demand elasticity (RDE) model. The article makes two major contributions. First, it focuses on a nontraditional exporter, who exports mainly wheat of mediocre quality to low-and middle-income countries. Second, the RDE model is estimated for the first time using a nonlinear estimator, the instrumental variable Poisson pseudo-maximum likelihood estimator. This is important because the double logarithmic functional form can provide biased results in the presence of heteroskedasticity. The results indicate that Russian wheat exporters can exercise market power in only a few markets, while they are price takers in the majority of importing countries.JEL classifications: L13, Q11, Q17, Q18
