Th e presented article focuses on an analysis of the phenomena appearing in the implementation of the transition from classic conventional technology in the production of agricultural food products to an ecological manner of farming. Th e main objective is an empirical analysis of the determinants of the implementation of ecological production technology, whereby not only is their defi nition focused on, but also the quantifi cation of the level of their eff ect. Th e primary methodological tool for achieving the objective is a binary choice model, which was estimated in three variants -probit model, logit model and linear probability model. Th ese estimations are conducted on the basis of the unbalanced panel data from 531 agricultural businesses -legal entities obtained over the time period [2004][2005][2006][2007][2008]. Results of the analyses indicate that the transition to and implementation of the organic production technology is negatively aff ected primarily by the higher age of the farmers and the high productivity of labour. On the other hand, the subsidies for the support of organic agriculture, as well as a high return on cost can be considered as the factors which positively infl uence the implementation of the organic technology. Given this fact, it is possible, through agricultural policy, to eff ectively infl uence the number of organically managing farmers, as well as the acreage of the organically managed land. And from the achieved outputs, the type of farm is subsequently characterised where a transition to organic farming may most likely be expected.

“…Consider X and Y independent variables with log-concave densities f X and f Y , which is satisfied by most common distributions (Bagnoli and Bergstrom 2005). This implies that X and Y have log-concave survival functions F X and F Y (Prékopa 1971(Prékopa , 1973.…”

We consider how information concentration affects a seller's revenue in common value auctions. The common value is a function of n random variables partitioned among m ≤ n bidders. For each partition, the seller devises an optimal mechanism. We show that, whenever the value function allows scalar sufficient statistics for each player's signals, the mechanism design problem is well-defined. Additionally, whenever a common regularity condition is satisfied, a coarser partition always reduces revenues. In particular, any merger or collusion among bidders reduces revenue.

“…10 If the density function F 0 is log-concave, then the distribution function F and the survival function 1−F are log-concave. See Burdett and Wright (1998) and Bagnoli and Bergstrom (2005) for details. Proposition 1 states that the price posting curve is downward sloping if the density function F 0 is log-concave.…”

“…It is important to emphasize that the price posting game is not responsible for the nonWalrasian outcome; the model with observable valuations and bilateral bargaining also leads to the non-Walrasian outcome. 4 As applications of the basic model, this paper considers various forms of market structure. In the basic model, each seller ignores how her price will influence the buyers' willingness to trade through its impact on their values of search (or, the values of their options to wait).…”

Price Setting and Competition with Search Frictions

This paper investigates price determination in a decentralized economy in which buyers' valuations are stochastic and unobservable. In such a market, each buyer's reservation utility depends both on the prevailing price and on the price he actually encounters. The buyer's willingness to trade is shown to be decreasing in the price, and this creates the trade-off for the sellers' price setting. Even though the sellers have incentives to manipulate the buyer's willingness to trade, the economy is not fully competitive; it does not converge to the Walrasian outcome as search frictions disappear. The model is used to study various market structures to explore the nature of market power in search equilibrium. It is shown that price dispersion arises as a result of search frictions and oligopolistic price setting.JEL classification: C78, D40
