This article offers a historical analysis of the contributions of U.S. interwar agricultural economics to the economics of information. Concerned with improving the circulation of information on agricultural markets, agricultural economists analyzed the relationship between agents' information and the behavior of prices on agricultural commodity exchanges, thus anticipating modern debates on informational efficiency. We show that these debates were part of a more general context of agricultural market reform led by the U.S. administration to improve the production and diffusion of economic information. We argue that such reforms were a prerequisite for theoretical discussions on information, and established institutional tools that are still active today, such as the USDA market news service.

Ces résultats mettent en avant un potentiel d’adaptations de la production des agriculteurs à des mesures environnementales. Previous studies on the productive value of biodiversity emphasized that crop diversity increases crop yields. Here, we focus on the productivity of crop diversity and permanent grasslands for crops and milk. Using a GMM approach, we estimate detailed production functions using a sample of 3960 mixed farms from the FADN between 2002 and 2013. We highlight that permanent grasslands enhance crop production. We confirm that crop diversity increases crop and milk yields. Permanent grasslands and crop diversity are however substitute inputs. We also find that both of these biodiversity productive capacities influence variable input productivities. These results suggest the potential adaptations of farmers’ choices to environmental measures.

AbstractThis paper presents a benchmark stochastic endogenous growth model of an agricultural economy. Producing food requires land, and increasing the share of total land devoted to farming mechanically reduces the share of land devoted to biodiversity conservation. However, safeguarding a greater number of species guarantees better ecosystem services, which in turn ensure lower volatility of agricultural productivity. The optimal conversion/conservation rule is explicitly characterized. Value of biodiversity is considered in its function of hedging against the volatility of agricultural production. Two aspects of biodiversity's value are examined. We first consider the total value of biodiversity as the welfare gain from biodiversity conservation, that is, the percentage increase in consumption that the society is willing to accept to give up the optimal level of biodiversity in favor of no biodiversity at all. We then consider the insurance value of biodiversity, extending the usual concepts to our stochastic dynamic framework, defining the insurance value of biodiversity as the change of the risk premium due to a marginal change in the level of biodiversity. To highlight the impact of risk on the optimal decision as in the value of biodiversity, we use the Epstein‐Zin‐Weil specification of preferences and represent preferences by a recursive utility function. This allows us to disentangle the effects of risk aversion and aversion to fluctuations. Thus, the preference for some rather uncertain outcomes and the propensity to smooth consumption over time are represented by two distinct parameters, and the effect of each of them are studied.
