  1. Agri-food cooperative enterprises: From Ballestero to Bijman

    Juliá Igual, Juan; Meliá Martí, Elena
    [EN] Agri-food cooperative enterprises have developed significantly in the EU and are expec-ted to take on an even greater role in the European agri-food industry. Professor Ballestero’s theory and Decalogue for the agricultural cooperative enterprises are particularly relevant. We relate them to the well-known recent European Commission report on farming cooperatives in Europe, led by professor Bijman, and considered to be the largest study to date. Our analysis clearly shows the extent to which professor Ballestero’s theses are still completely valid today.

  2. The Environmental Protection as a selection criterion in Socially Responsible Investments: A multicriteria approach

    García-Bernabeu, Ana; Pla-Santamaria, David; BRAVO SELLES, MILAGROS; Pérez-Gladish, Blanca
    [EN] A greater environmental and ethical awareness of companies and organizations is also ap-plied to portfolio selection. This note aims to put forward a multicriteria model of Goal Programming (GP) to design efficient portfolios considering classic financial criteria and environmental criteria

  3. Reseña del libro Los nuevos viñadores. Una nueva generación de viticultores españoles

    Parga-Dans, Eva; Alonso González, Pablo
    [ES] Nuevos paradigmas productivos y tendencias de consumo están cuestionando el establishment del vino en España; transformaciones sociales que requieren una reflexión crítica y analítica por parte de la economía, la antropología, la sociología y el ámbito de la alimentación en general, o al menos así debería ser. Luis Gutiérrez, en su primer libro, nos introduce en este debate preguntándonos qué comparte un caballero que ha elaborado durante toda su vida prestigiosos vinos de Jerez, con el hijo de un albañil que lleva trabajando más de una década para una gran bodega industrial, pero que se ha gastado su salario...

  4. Factors influencing peach farmer income in the province of Tungurahua, Ecuador

    Viera, William; Viera, Alex; Martínez, Aníbal; Jácome, Rosendo; Ayala, Germán; Sotomayor, Andrea; Galarza, David; Ron, Lenin
    [EN] Tungurahua province has conditions suitable for growing deciduous fruit trees such as peach (Prunus persica L). This research aimed to identify the main factors influencing the production of this fruit crop and their effect on farmers income. Surveys were carried out directly to peach farmers in seven counties of Tungurahua such as Ambato, Cevallos, Mocha, Patate, Pelileo, Píllaro and Tisaleo. The results indicated that the most relevant factors were: farmer age, sown area, fruit selection, reason for fruit growing, type of production and production issues.

  5. Total factor productivity and its components for sheep and goat farms in 37 Southern European regions (2004-2012)

    Hidalgo González, Cristina; Rodríguez Fernández, Mª Pilar
    [EN] The decline of Southern Europe’s traditional sheep- and goat-farming systems creates a need for studies on the economic determinants that underlie their production processes. Using data from the FADN, we built a panel of 37 regions from 5 countries over an 8-year period (2004–2012). A Cobb-Douglas was specified and a stochastic frontier production was estimated. Total Factor Productivity (TFP) and its components were calculated. The farms have had sustained, positive development of TFP since 2008, with a significant correlation with the labour factor of production. We detected moderate technical progress change, which was accompanied by decreasing efficiency.

  6. La implicación de los agentes sociales y económicos en el desarrollo rural: una necesidad insatisfecha

    Moyano Pesquera, Pedro Benito
    [EN] The rural development policy applied by the European Union during the 2007-2013 pro-gramming period represented an important turning point, as it incorporated a transversal methodological approach reflected in Axis 4. LEADER, which transfers the accumulated experience from 1991 by the LEADER Initiative to the rural development programming. Among other aspects, local actors embedded in the territory are entrusted with the design and implementation of the rural development strategy. These local actors are formally organized in Local Action Groups (LAGs). The aim of this paper is to determine to which extent the 264 LAGs have assumed the philosophy of this...

  7. The lack of alternative income sources: The case of ornamental fishing in the Inirida fluvial confluence, Colombian Amazon

    Guerrero, Daniel; Franco-Jaramillo, Marcela; Rosell, Jordi
    [EN] In this paper we present a case study of the impoverished ornamental fishing situation in the Inirida Fluvial Confluence (IFC) in Colombia. For this purpose fieldwork was conducted to obtain primary data from fishermen in the zone. The results indicate that effort applied to create different economic activities have no significant impact on the income of fishermen. Community Agreements for Responsible Fishing (CARF) could be an effective policy for management of the resource; nevertheless, their establishment can bring a loss of livelihoods when there are no clear alternative income sources, and may be incompatible with poverty alleviation objectives. Due...

  8. Competitive advantage differences between firms belonging to a business group and independent companies in the Spanish wine industry

    Ferrer-Lorenzo, Juan Ramón; Abella-Garcés, Silvia; Maza-Rubio, Teresa
    [EN] A high percentage of companies that compete in the market belong to a business group. This paper analyses the competitive advantages between independent firms and firms belonging to a business group, focusing on the Spanish wine industry. The authors studied 339 wineries, compared their resources and capabilities, the strategies used and their business performance. The results suggest that while resources and capabilities are key for independent firms it is the business strategy that is most important for firms belonging to a business group. The study sheds more light on the application of specific elements to explain a firm’s business...

  9. Designing a whole-farm revenue insurance for agricultural crops in Zanjan province of Iran

    Ghahremanzadeh, Mohammad; Mohammadrezaei, Rassul; Dashti, Ghader; Ainollahi, Moharram
    [EN] The purpose of this article is to design and empirically evaluate the Whole Farm Insurance (WFI) over the conventional insurance programs in Zanjan province of Iran. Historical farm-level and county-level data were used to estimate yield and price density functions. Both parametric and non-parametric methods were applied for predicting the future values and the PQH simulation method was utilized to calculate premium rates. Results revealed that loss ratios of the WFI are lower for farmers who insured more than one crop. Additionally, utilizing WFI reduces premiums. Moreover, premiums obtained from nonparametric method are relatively lower compared to the parametric...

  11. Valores de igualdad de género y especialización: diferencias entre las regiones de la UE

    Quispe Salazar, Eduardo; San Juan Mesonada, Carlos
    [EN] We empirically contrast the Boserup hypothesis for the regions of the European Union. We relate the dominant productive orientation in each region (plough, hoe, animal) with indicators of gender equality: female participation in management positions, in primary education, in higher education, in the labor market and the average hourly wage. Using a Probit model we find that, consistently with the hypothesis, there is a negative relationship between indicators and plough agriculture. Additionally, we prove that livestock-oriented regions also generate less egalitarian gender values than hoe-oriented regions.

  12. Valoración de la oferta de bienes públicos por parte de los sistemas agrarios: el caso del olivar de montaña en Andalucía

    Villanueva, Anastasio J.; Gómez-Limón, José A.; Rodríguez-Entrena, Macario
    [EN] We carried out an economic valuation of public goods (PGs) provided by Andalusian mountainous olive groves using choice experiments. The results show varying farmers’ behaviour depending on the level of stringency of the requirements included in agri-environmental schemes, with willingness to accept (WTA) lower than € 80/ha for less stringent scenarios (such as those associated with integrate production) and WTA higher than € 300/ha for the most stringent scenario (designed to maximise the provision of environmental PGs). The study also indicates that the inclusion of a results-based bonus has a low relevance

  13. Valuating intangible benefits from afforested areas: A case study in India

    Jain, Avinash; Chandra, Girish; Nautiyal, Raman
    [EN] Environmental compensation measures usually accompany energy projects. Willingness-To-Pay (WTP) for five intangible benefits derived from afforested areas of a compensatory afforesta-tion programme of National Thermal Power Corporation Dadri are estimated. Conventional Contingent Valuation shows the average WTP € 2.1 per respondent per month with more than 43 % of total WTP for ‘soil conservation and remediation’ and ‘improvement in underground water level’. Logit model method depicts the same order of magnitude but differs significantly at 5 % level for all the benefits. More in-formed decisions upon energy projects and afforestation programs shall help in conserving forests and their ecosystem...

  14. Evaluation of risk management tools for stabilising farm income under CAP 2014-2020

    Castañeda-Vera, Alba; Garrido, Alberto
    [EN] Guaranteeing farm income stability is an objective of the European Union’s and the Spanish agricultural policies. In this paper, CAP direct payments, diversification, crop insurance and an Income Stabilisation Tool (IST) were compared considering (i) their effect on farm income and income stability, (ii) the expected farmers’ willingness for adoption, and (iii) the efficiency of public expenditure invested in supporting them. Main conclusions point at direct payments and crop diversification as the most effective measures in decreasing income variability. Nevertheless, using crop insurance or an IST has potential for both improving farm resilience to income variability and limiting public...

  15. Cultivos leñosos en Aragón: evaluación económica de una eventual prohibición del glifosato

    Martínez, Yolanda; Pardo, Gabriel
    [EN] Conservation agriculture systems are linked to glyphosate as the main herbicide in tree crops. The recent debate on possible negative effects over human health has increased the farmers’ concern about an eventual prohibition of glyphosate in the future. The aim of this paper is to estimate the costs associated with an eventual prohibition of glyphosate in tree crops of Aragon. The costs of different alternative strategies were calculated: substitution of glyphosate in chemical control, minimum tillage, and natural or planted vegetal covers.

  16. Tax neutrality in determining farmers’ incomes; an issue that needs to be resolved

    Marí-Vidal, Sergio; Campos-Campillo, Ernesto
    [EN] Net income from agricultural activities to calculate personal income tax can be determined either by different methods, but whatever method is used the aim should be to obtain the same result in all cases (neutrality). The aim of this study is twofold: on the one hand to analyze the neutrality of the OA method as compared to the SDA method. On the other hand to devise a method that provides the net income index that when applied would ensure the neutrality of the OA method. The results obtained confirm the lack of neutrality. Also it could be interesting to...

  17. Sanitary and Phytosanitary measures in agri-food imports from the European Union: Reputation effects over time

    Taghouti, Ibtissem; Martinez Gomez, Victor David; Marti, Luisa
    [EN] The EU’s Rapid Alert System for Food and Feed provides information on sanitary and phytosanitary (SPS) notifications. With a set of data from the 1998-2013 period, we test the hypothesis that past notifications can determine current notifications. This is the “reputation effect”, meaning that inspectors may tend to target products or countries with previous SPS problems. We analyze the scope of the reputation effect over time. We used two count data models to estimate the distribution of current notifications. In line with previous literature, our findings indicate that reputation does affect current EU notifications. Furthermore, we identify some relevant...

  19. Implicaciones de la disminución de la capacidad productiva de granos básicos sobre la alimentación en comunidades rurales pobres de México

    Quintero Peralta, María Angélica; Gallardo Cobos, Rosa María; Ceña Delgado, Felisa
    [EN] The structural changes ensuing from the policies implemented in the primary sector in Mexico have led to the deterioration of food production capacity in small producers, increasing rural poverty. We performed 132 interviews with small producers in Hidalgo, Mexico and Morelos to assess production conditions and income, and used a multinomial logistic regression model to assess food self-sufficiency. The results indicate that if the level of food production is not substantially changed, then the probability of improving food self-sufficiency is low; giving rise to the subsequent deepening of poverty.

  20. Capacidades dinámicas en el proceso de internacionalización de las empresas de distribución de productos agroalimentarios

    Calderón García, Haydee; Kolbe, Diana
    [EN] The agri-food sector faces important internal and external barriers to internationalization that could be overcome by the development of dynamic capabilities. Generic dynamic capabilities generate sector and environment specific dynamic capabilities that directly contribute to overcome the barriers of internationalization. Our contribution is to determine which specific dynamic capabilities of the distribution companies collaborate to overcome these barriers and as a consequence to improve international results. A qualitative study with directors and managers of the sector was carried out. The results give rise to confirm that the specific dynamic capabilities largely help to resolve the internal barriers that hinder...
