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.

Village poultry, also termed “bicycle poultry” is produced in scavenging farming systems and is a chewy meat with a low fat content, and constitutes an important source of meat in many African countries. This study investigates consumers’ preferences regarding the physical traits of these birds (notably chickens, ducks and guinea fowl) in the Republic of Benin. For this purpose, we applied the hedonic price method on field data collected from retailers in four urban and five rural markets. We found that meatier drake and meatier guinea fowl with white plumage are preferred by consumers who are willing to pay a premium for these types of birds. The factors which significantly influence the price of chicken are the breed of the bird, the plumage color, the meatiness and the age of the bird. Consumers are willing to pay a price premium for meatier birds of traditional breeds with white plumage color and aged between six and twelve months. Thus, efforts to improve local breeds should stress these preferred traits. Sodjinou Epiphane, Henningsen Arne, Olorounto Koudandé Delphin, Biaou Gauthier, Mensah Guy Apollinaire.

A lot of experimental studies of the TIR anisotropy, which is defined as the difference between oblique and nadir surface temperatures measurements, have been performed since the 60’s and reported in literature. They reveal important hotspot effect and possible significant errors - up to 10°C - on surface temperature measurements. Directional effects have to be characterized to correct or to normalize satellite data, particularly large swath satellites data such as MODIS or AATSR for which scan angles reach ± 55° and ± 47° from nadir, respectively. They also have to be considered for defining the mission specifications of future TIR systems. Finally they can help to improve the estimation of surface fluxes by making possible discriminating the contributions of soil and canopy. In this idea a better characterization of TIR directional anisotropy is expected to improve the assimilation of thermal satellite data in vegetation models. A large range of approaches have been developed to simulate the anisotropy (geometric models, radiative transfer, 3D models, parametric kernels...). Nevertheless, deterministic radiative transfer modelization remains essential to generalize experimental measurements and to assess the sensitivity of surface features (vegetation structure, LAI, water status etc.) and the impact of the Sun-observer geometry impact on directional radiative temperature measurements. Moreover, new methods (such as kernel approaches or neural networks) have to be developed to correct for directional anisotropy, simple enough to be integrated in ground segments for operational satellite data processing. For this purpose another use of a deterministic model of TIR anisotropy could be the simulation of data sets from which derive operational simpler algorithms could be derived. The deterministic SCOPE (Soil Canopy Observation, photochemistry and Energy fluxes) model, developed by Van der Tol et al. (2009) at the ITC (Nederland), is a good candidate to address the problem of the temperature anisotropy. It is a one-dimensional multilayer model coupling a radiative transfer model based on the 4SAIL (Scattering by Arbitrary Inclined Leaves designed by Verhoef et al. 2007) algorithm and an energy balance module. It has been designed to simulate radiance spectra, energy and CO 2 fluxes but it also simulates directional brightness temperatures. After a brief description of the model, we present a validation exercise of SCOPE for fluxes and directional brightness temperatures over two original experimental data sets obtained on wheat and pine stands recorded during different years; they offer a large range of surface conditions (vegetation structure, LAI, water status). Directional radiative temperatures were measured with several radiothermometers positioned in different zenithal and azimuthal viewing configurations (18° towards South, 55° towards North and 27° towards West). During a few months, a GV2M: Global Vegetation Monitoring and Modeling (18° towards South, 55° towards North and 27° towards West). During a few months, a radiothermometer was also mounted on a motorized platform piloted to follow the sun course during the day, so providing the temperature at the hotspot. The sites belonging to different international networks, (CarboEurope, Fluxnet) the energy (sensible and latent heat) and CO 2 fluxes were also continuously monitored. SCOPE was calibrated using several inversion strategies which are described. The biochemical input parameters (maximal carboxylation capacity and the marginal cost of assimilation which strongly govern photosynthesis and transpiration processes) revealed to have most sensitivity on simulations and were retained to calibrate the model. The validation of SCOPE was made on cloudless days and for diurnal conditions only. Satisfactory results have been obtained on fluxes with a root mean square error (RMSE) on convective fluxes estimation of about 40 W.m- 2. The simulation of directional brightness surface temperatures revealed excellent with a 1°C RMSE over both wheat and pine data sets, and for all viewing geometries. The use of SCOPE for generating polar plots of temperature anisotropy is finally illustrated by a qualitative comparison exercise. Simulations revealed directional anisotropy structure quite consistent with measurements available at the laboratory. The applications to evaluate the possible effects of different variables such as vegetation structure (leaf angles, LAI, etc.) and micrometeorological conditions (wind speed for instance) are discussed.

Nous examinons ici la productivité de la diversité des cultures et des prairies permanentes pour les céréales et le lait. A partir de la méthode des moments généralisés, nous estimons un système de fonctions de production détaillées sur un échantillon de 3960 fermes du RICA spécialisées en polyculture-élevage entre 2002 et 2013. Nous trouvons que les prairies permanentes augmentent les rendements des cultures. Nous confirmons que la diversité des cultures augmente les rendements des cultures mais aussi les rendements laitiers. Cependant, nous trouvons que la diversité des cultures et les prairies permanentes sont substituables. Elles interagissent par ailleurs avec les intrants variables. 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.

A lot of experimental studies of the TIR anisotropy, which is defined as the difference between oblique and nadir surface temperatures measurements, have been performed since the 60’s and reported in literature. They reveal important hotspot effect and possible significant errors - up to 10°C - on surface temperature measurements. Directional effects have to be characterized to correct or to normalize satellite data, particularly large swath satellites data such as MODIS or AATSR for which scan angles reach ± 55° and ± 47° from nadir, respectively. They also have to be considered for defining the mission specifications of future TIR systems. Finally they can help to improve the estimation of surface fluxes by making possible discriminating the contributions of soil and canopy. In this idea a better characterization of TIR directional anisotropy is expected to improve the assimilation of thermal satellite data in vegetation models. A large range of approaches have been developed to simulate the anisotropy (geometric models, radiative transfer, 3D models, parametric kernels...). Nevertheless, deterministic radiative transfer modelization remains essential to generalize experimental measurements and to assess the sensitivity of surface features (vegetation structure, LAI, water status etc.) and the impact of the Sun-observer geometry impact on directional radiative temperature measurements. Moreover, new methods (such as kernel approaches or neural networks) have to be developed to correct for directional anisotropy, simple enough to be integrated in ground segments for operational satellite data processing. For this purpose another use of a deterministic model of TIR anisotropy could be the simulation of data sets from which derive operational simpler algorithms could be derived. The deterministic SCOPE (Soil Canopy Observation, photochemistry and Energy fluxes) model, developed by Van der Tol et al. (2009) at the ITC (Nederland), is a good candidate to address the problem of the temperature anisotropy. It is a one-dimensional multilayer model coupling a radiative transfer model based on the 4SAIL (Scattering by Arbitrary Inclined Leaves designed by Verhoef et al. 2007) algorithm and an energy balance module. It has been designed to simulate radiance spectra, energy and CO 2 fluxes but it also simulates directional brightness temperatures. After a brief description of the model, we present a validation exercise of SCOPE for fluxes and directional brightness temperatures over two original experimental data sets obtained on wheat and pine stands recorded during different years; they offer a large range of surface conditions (vegetation structure, LAI, water status). Directional radiative temperatures were measured with several radiothermometers positioned in different zenithal and azimuthal viewing configurations (18° towards South, 55° towards North and 27° towards West). During a few months, a GV2M: Global Vegetation Monitoring and Modeling (18° towards South, 55° towards North and 27° towards West). During a few months, a radiothermometer was also mounted on a motorized platform piloted to follow the sun course during the day, so providing the temperature at the hotspot. The sites belonging to different international networks, (CarboEurope, Fluxnet) the energy (sensible and latent heat) and CO 2 fluxes were also continuously monitored. SCOPE was calibrated using several inversion strategies which are described. The biochemical input parameters (maximal carboxylation capacity and the marginal cost of assimilation which strongly govern photosynthesis and transpiration processes) revealed to have most sensitivity on simulations and were retained to calibrate the model. The validation of SCOPE was made on cloudless days and for diurnal conditions only. Satisfactory results have been obtained on fluxes with a root mean square error (RMSE) on convective fluxes estimation of about 40 W.m- 2. The simulation of directional brightness surface temperatures revealed excellent with a 1°C RMSE over both wheat and pine data sets, and for all viewing geometries. The use of SCOPE for generating polar plots of temperature anisotropy is finally illustrated by a qualitative comparison exercise. Simulations revealed directional anisotropy structure quite consistent with measurements available at the laboratory. The applications to evaluate the possible effects of different variables such as vegetation structure (leaf angles, LAI, etc.) and micrometeorological conditions (wind speed for instance) are discussed.

Nous examinons ici la productivité de la diversité des cultures et des prairies permanentes pour les céréales et le lait. A partir de la méthode des moments généralisés, nous estimons un système de fonctions de production détaillées sur un échantillon de 3960 fermes du RICA spécialisées en polyculture-élevage entre 2002 et 2013. Nous trouvons que les prairies permanentes augmentent les rendements des cultures. Nous confirmons que la diversité des cultures augmente les rendements des cultures mais aussi les rendements laitiers. Cependant, nous trouvons que la diversité des cultures et les prairies permanentes sont substituables. Elles interagissent par ailleurs avec les intrants variables. 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.
