| Water availability in semiarid regions commonly exhibits patterns of extreme variability. Even in basins with large infrastructure development, some users are subject to low levels of water reliability, incurring economic losses during periods of scarcity. More flexible instruments, such as voluntary exchanges of water among users, may help users reduce their risk exposure. Recent changes in the Spanish water Law have given an initial impulse to allow for lease-out contracts of water use rights. This paper analyses, from theoretical and empirical standpoints, the effect that establishing water markets has on the economic risk caused by water availability variations. The empirical study is performed on an irrigation district of the Guadalquivir Valley... |

| Since 1996, different formats of whole-farm insurance (WFI) have been launched in North America and Spain. Their rationale is to pool all farm's insurable risks into a single policy that provides cheaper coverage against the farm's revenue losses. We evaluate the gains of moving from a situation of full insurance coverage delivered by crop-specific policies to WFI. Based on the records of individual farmers gathered by the Spanish Agricultural Insurance Agency (ENESA), we select two representative farms in Valencia that have consistently purchased insurance during 1993-2004 for three crops (apricots, plums and wine grapes). WFI is designed to deliver exactly the same expected revenue than does the combined effects of three crop-specific multiple-peril... |

| En 2003 y 2004, se ofreció por primera vez en España un seguro que protege contra la caída de precios en origen de un producto agrícola. Se trata de un seguro de rentas lanzado con carácter piloto para las producciones de patata de media estación y patata tardía en cinco provincias españolas (Álava, Burgos, La Rioja, León y Valladolid). El objetivo de este trabajo es describir las características del seguro y realizar una evaluación preliminar de las campañas en que ha funcionado. Se parte de una aproximación conceptual a los instrumentos de gestión de riesgos de mercado, en cuyo contexto se enmarca el presente seguro. Posteriormente se explica el modelo de precios empleado para definir los precios de referencia del mercado y las primas, contrastando la... |

| Water availability in semiarid regions usually exhibits patterns of extreme variability. Even in intensively controlled basins, some users are subject to low levels of water reliability, and more vulnerable to periods of extreme scarcity. To reduce their risk exposure more flexible instruments, such as voluntary exchanges of water among users, are required. Recent changes in the Spanish water Law have given an initial impulse to allow for leases of water use rights. Properly designed and monitored, this instrument provides some flexibility to water management, and may increase the economic use efficiency as well as mitigate the adverse economic effects of droughts. This paper looks at the risks and uncertainty dimensions of water markets, which have not... |

| RESUMEN: En este artículo se analizan un conjunto de políticas de estabilización de los ingresos de los productores olivareros españoles, entre las que se incluyen seguros de rendimientos e ingresos. En teoría y bajo ciertos supuestos, la estabilización de los ingresos con un seguro de ingresos se puede lograr a un coste inferior al uso combinado de seguros de rendimientos y un seguro de precios. Tras revisar algunas experiencias con seguros de ingresos, se desarrolla una aplicación para comparar, desde la doble perspectiva de eficacia en el gasto público y de reducción de riesgos, distintas políticas de intervención en el sector olivarero, incluyendo las de los pagos actuales, ayuda al árbol, seguro de rendimientos actual y un seguro de ingresos. Los... |

| This paper attempts to draw conclusions regarding Risk Management instruments (RMI) for potential development or expansion in the EU (Garrido and Bielza, 2007). Using data from EU countries, compiled in the course of two EU research projects about RMIs, we perform a cross-sectional analysis of the role of agricultural insurance and ad hoc payments. Tests of comparisons of means of key insurance data reveal the impact of insurance policies and the degree of competitiveness in supply side. While the presence of subsidies explains differences across EU member states' (MSs) insurance data, the degree of competitiveness is not a differentiating factor. In the last part of the paper, we rate a number of RMIs on the basis of a number of criteria. We conclude that... |

| We use the actual insurance records of 52,300 farmers and 11 years to estimate two sets of insurance demands. We define measures of insurance's expected returns, variance and third moment, based on observed insurance data, and infer the expected returns for those farmers that have never had an indemnity. We estimate several probit models and count models for the insuring vs non-insuring strategies, in which the economic returns of insurance and its two measures of dispersion enter as explanatory variables. Results show that farmers' insurance strategies are largely explained by their actual insurance experience as captured by these three variables. Individuals with loss rations greater than 1 do not show more responsiveness that those facing more balanced... |

| This paper explores and analyzes farmers’ risk perceptions, risk management instruments’ demand and usage in five Member States (Hungary, Spain, the Netherlands, Germany and Poland). A survey completed by 1047 representative farmers of these EU Member Status collected information that allowed us to set apart two focus areas: the first looks at the declared importance of several sources of farms’ risk and income instability, and at the actual means that farmers pursue to manage and face them. The second area focuses on the demand for risk management instruments. The paper’s objective is to determine the factors that explain farmers’ responses in the first area, and based on those factors, analyse the demands for two instruments (insurance, and future &... |

| Various forms of revenue insurance have been applied in Canada and in the US with relative success. In this paper different combinations of traditional agricultural policies and revenue and yield insurance are analysed for the Spanish olive oil sector. Taking a database containing about half million Spanish olive growers during 8 campaigns, five possible policies are studied and the results are examined according to different criteria including average revenue and its variability, growers utility gains, taxpayers cost and the transfer efficiency of support. The policies analysed are: (1) non-intervention; (2) the policy currently in force in Spain that combines a production aid with a yield insurance; (3) a revenue insurance, only; (4) revenue insurance... |

| This paper proposes an Economic Drought Management Index (EDMI) that could assist water managers to inter-temporally manage water reservoirs. The index's main appeal is that it can be easily interpreted and that encompasses in a single number hydrological processes, structural constraints, water institutions' rules and the economic benefits of the customers served from the supply system. An empirical application of EDMIs is performed for two irrigation districts in Andalusia (Southern Spain), that are managed under different institutional arrangements. Results for one district show that the region's vulnerability to drought could be reduced following the interpretation of the EDMIs. For the other district, the index shows that water stocks are managed... |
