| Spain occupies the first position in the European and Mediterranean rankings of citrus production and trade. In our analysis we assess the technical efficiency with which this sector is operating. The main objective of this study is to analyze productivity and technical efficiency of Spanish citrus sector through citrus farms with high orange production. A stochastic frontier production model is estimated in which the technical inefficiency effects are defined by the time-varying inefficiency model. A primal approach is used to decompose Total Factor Productivity (TFP) growth into its various components. Results indicate improvement in efficiency scores of Spanish citrus farms along the period studied. Allocative efficiencies, technical efficiency change,... |

| This paper studies the extent to which decoupled income support measures in agriculture can have production implications both at the extensive and intensive margins. We develop a theoretical framework that analyzes production responses of agricultural producers to apparently decoupled payments, by explicitly considering risk attitudes and uncertainty. We use farm-level data collected in Kansas to estimate the model. Technology and risk preference parameters are jointly estimated. Results show that though lump sum payments are not fully decoupled in the presence of risk and uncertainty, their effects on agricultural production are likely to be of a very small magnitude. |

| Off-farm investment decisions of farm households are analyzed. Farm-level data for a sample of Kansas farms observed from 1994 through 2000 are utilized. A system of censored dependent variables is estimated to investigate the factors that influence the composition of farm households' portfolios. The central question underlying the analysis is whether farm income variability influences off-farm investment decisions. Previous analyses on the determinants of non-farm investments have failed to consider the role of income variability. Our results indicate that higher farm income fluctuations increase the relevance of non-farm assets in the farm household portfolio, thus suggesting that these assets are used as farm risk management tools. |

| The growing importance of economic factors in farmers decision to go organic has raised interest in characterizing the economic behavior of organic versus conventional farms. Published analyses so far have not considered differential uncertainties and farmers risk preferences between conventional and organic practices when comparing these techniques. Our article attempts to assess this issue. We use a model of farmer decision under risk to analyze the differential values between Spanish COP organic and conventional farms and to assess the incentives for adoption of organic practices. Results show that organic and conventional farms do have different abilities to control production risk as well as different risk preferences. Organic price premiums and... |

| We focus on determining the impacts of government programs on farms technical inefficiency levels. We use Kumbhakars (2002) stochastic frontier model that accounts for both production risks and risk preferences. Our theoretical framework shows that decoupled government transfers are likely to increase (decrease) DARA (IARA) farmers production inefficiencies if variable inputs are risk decreasing. However, the impacts of decoupled payments cannot be anticipated if variable inputs are risk increasing. We use farm-level data collected in Kansas to illustrate the model. |

| This paper assesses the impacts of decoupled government transfers on production decisions of a sample of Kansas farms observed from 1996 to 2001. Our model allows for risk, risk attitudes and the intertemporal investment decisions. We also allow for different adjustments of the decision variables depending on the predominant economic conditions. The theoretical model is estimated using the threshold regression methods proposed by Hansen (1999). Threshold effects are allowed to characterize the behavior of output supply and quasi-fixed and variable input demand.. The econometric results support the existence of three regimes characterized by different economic behavior. Our analysis suggests that in a dynamic setting with risk and non-risk neutral economic... |

| The crop insurance purchase decision for a group of Kansas farmers is analyzed using data from 1990sa period that experienced many changes in the federal crop insurance program. Farm-level data are used. Results indicate a reduction in the elasticity of the demand for crop insurance with respect to premium rates by the end of the decade. This corresponded with a considerable increase in government subsidies by the end of the 1990s. This may also reflect the attractiveness of new revenue insurance products that may have made producers less sensitive to premium changes. |

| Asymmetric threshold error correction models are used to analyze price relationships and patterns of transmission among farm and retail markets for a variety of dairy products in Spain. Our empirical analysis is conducted using both weekly and monthly price data. Our results suggest that the transmission of shocks is largely unidirectional, running from the farm to retail levels. Formal tests confirm asymmetries, though our results suggest that the effects of these asymmetries are modest. Implications for the organizational structure of Spanish dairy markets are offered. |
