Article
Purpose This paper explores the importance of the importing intensity for different intermediate inputs depending on their source (internal sourcing or intra-firm trade versus external sourcing or foreign suppliers) for different types of innovation (product and process innovation) and applied to MNEs (foreign versus domestic). Design/methodology/...
Article
Purpose This study aims to focus on relational social capital in family wineries. Relational social capital is influenced by the family nature of the business and is at the same time a key antecedent of winery performance. The aim is to analyse these relationships in the qualified denomination of origin (DOC) Rioja wine industry (Spain). Design/me...
Chapter
This chapter examines the factors determining international expansion for a group of Spanish family SMEs. Internationalization is modelled taking into account both the decision to enter foreign markets and the degree of internationalization. This chapter uses the information provided by the Survey on Business Strategies in Spain, including 1,519 ob...

This paper studies the relationship between internationalization and performance in agri-food firms. In line with the recent literature, it analyses the effects of the degree of internationalization using a uniform sample, a long-term focus and a measure that combines export intensity and regional diversification. The study empirically confirms the...
Article
Full-text available
In spite of the extensive presence of Science Parks in developed countries, it is still unclear whether they have been successful in fostering the innovation performance of new technology-based firms (NTBFs). The aim of this paper is to help answer exactly this question. Using an unbalanced panel of 7691 observations associated with 1933 Spanish NT...
Article
Full-text available
We argue that the benefits provided by locations inside science and technology parks evolve over time. Firms inside parks can improve performance due to certain advantages related to knowledge spillovers and shared resources that can be particularly useful in earlier stages of the industry life cycle. In these industries, local knowledge sharing is...
Article
This paper presents a framework to assess the effects of technology collaboration networks (TCNs) on the innovation performance of small and medium-sized enterprises (SME). It includes three factors that affect firm dynamics and could influence the success of the TCN: the macroeconomic cycle (macro-level), the industry life cycle (industry-level) a...
Article
Full-text available
The objective of this research is to evaluate the effect of the economic recession on the performance of firms located in science or technological parks. Compared to off-park firms, we propose that under an economic crisis park benefits are more noticeable, since firms located inside parks have less resource restraints and access to external source...
Article
Full-text available
This study evaluates the importance of product differentiation as a determinant of vertical integration in firms. The proposed model also controls for known determinants of integration, such as transaction costs and firm-level capabilities. By identifying transaction-, firm- and strategy-level determinants, we derive testable predictions about the...
Article
Full-text available
Previous studies have provided mixed evidence on the relationship between internationalisation and firm performance. We advance theoretically in this line of research by investigating the impact of the family dimension of a business on this relationship. Using a panel data analysis for the 2006–2011 period, we find empirically that Spanish family S...

Design/methodology/approach – The authors have taken into account two main approaches: a cluster...
Article
Full-text available
Selecting an export channel is one of the most important strategic decisions for any exporting agri-food firm. This paper presents a unified theoretical framework, integrating the two decisions (i.e., the export decision itself and the export channel decision) by jointly examining the effects of 1) intangible resources, 2) product quality, 3) firm...
Article
Full-text available
This research evaluates the role of science and technology parks as locations fostering local knowledge exchange and promoting innovation. We consider that these knowledge externalities depend on firms’ internal efforts and strategies, since their capacity to understand and exploit others’ knowledge depends on their own knowledge base. Empirical ev...
Article
This research aims to complement resource-based view with a cluster approach in identifying which elements, both internal to the firm and locally available, improve firms’ export performance. While in the resource-based view exporting firms are contingent upon the development of intangible resources, from a cluster approach exporters exploit local...
Article
This research tries to explain the importance of intangible resources in explaining the international diversification of small and medium sized enterprises (SMEs). Our starting position is that SMEs diversify to leverage their resources across different markets, and therefore a positive relationship is to be expected between technological, human an...
Article
Full-text available
This research paper tries to analyse the role that knowledge about foreign markets has in increasing firms' exports in clustered spaces. We consider two interrelated sources of this knowledge, a firm's direct experience and its indirect experience from other clustered firms. In particular, it is proposed that firms can improve their export performa...
Article
Full-text available
This research evaluates the role of local technology institutions as an external source of ideas, information and knowledge that foster innovation and enhance the performance of firms. It is argued that firms that establish links with local technology institutions have access to valuable external information and knowledge flows, which in turn impro...
Article
Full-text available
Relatively few empirical analyses have attempted to understand the export behavior of small and medium-sized enterprises, and even fewer have examined the wine industry. The purpose of this research is to apply the resource-based view to investigate the determinants of international expansion in the wine industry. Using a sample of 177 firms in the...
Article
Purpose – The aim of this research is to determine how trust might moderate the effect of asset specificity on the contractual choice. Design/methodology/approach – The sample is drawn from the qualified appellation of origin (DOCa) Rioja wine market. A binomial logit was used as the primary technique for investigation of the hypothesis for the fin...
Article
The objective of this paper is to analyze the effect of linear sharing contracts when downstream retail prices are used for compensation in a context of imperfect information about food quality. Such outcome-sharing through retail price contracts can be explained directly by agency theory. While the case of both parties being subject to moral hazar...
Article
This paper investigates how wineries' decisions to grow or buy their provisions of grape affect their viticultural performance. While previous literature in agrarian economics suggests a direct association between vertical integration and performance, this research largely neglects the impact of transaction cost variables on governance mode choice...
Article
Full-text available
This paper uses the principal-agent theory to analytically investigate the optimal incentive-based compensation contract that a processor should offer to a grower performing efforts in quantity and quality. In this process, we contribute to the substantive literature on multi-task principal-agent models by analyzing the quality-quantity trade-off a...

The purpose of this study is to determine students´ perception with regard to mobility. The data source used was specifically designed based on a questionnaire that was provided to...
Article
Full-text available
The authors study the determinants of make or buy decisions for grapes made by wineries belonging to the Rioja Qualified Designation of Origin (DOCa). In particular, they analyze the relationship between product quality and vertical integration. Although there is a long tradition in transaction cost theory of analyzing the determinants of make or b...

Should a landlord adopt a wage labor, a crop sharing or a fixed-payment land rental contract with a particular tenant? The emergence of the agency theory to the contract choice in the 1970s and 1980s has generated a substantial body of theoretical and empirical research on why and under what conditions each contract is chosen. This paper reviews th...
Article
This paper attempts to develop a consistent theory for the choice of performance contracts in agriculture by analyzing the trade-off between quantity and quality and the presence of competence and uncertainty on the basis of the expected utility theory. This theory is able to explain many contract-related issues, such as why the performance contrac...
Article
Full-text available
The central purpose of this paper is to examine the incentive contract as an equilibrium phenomenon. We analyse a model of vertical differentiation in which we deal with the strategic role of the competitor’s decisions in a successive duopoly. Is it better for a processor to offer an incentive contract to an upstream producer or the spot market? We...
Article
Full-text available
This study analysed the relationship between product quality and governance mode choice (market mode, hybrid mode or vertical integration) using the results of a survey of 187 qualified appellation of origin (DOC) Rioja wineries. By estimating a generalized ordered logit, it is concluded that wineries that produce high-quality wines are more likely...
Article
El objetivo del presente trabajo es doble. El primero es promover el debate en torno al rol que verdaderamente desempeña la regulación en relación con la calidad en el sector agroalimentario. Para ello se cuestionan las reformas legales que propugnan que la calidad alimentaria consiste sólo en un conjunto de medidas para evitar fraudes alimentarios...
Article
This study applied a multi-theoretical perspective to explore factors that determine the duration of continuing supply relationships between grape processors and growers. Our empirical study employed hazard rate models with time-varying covariates, using data from supply contracts between wineries and growers in the DOCa Rioja wine industry. We fou...
Article
Full-text available
This article develops and tests a model of integration of the first stage of the wine value chain, i.e. the viticulture activity. The model, derived from the transaction cost analysis developed princi- pally by Williamson, is formulated as a tobit function, which is estimated with data from the wine in- dustry in the Rioja's denomination of origin....
Article
Full-text available
El presente trabajo desarrolla y comprueba empíricamente un modelo de integración vertical de la primera etapa de la cadena de valor del vino, la viticultura. El modelo, derivado del análisis de costes de transacción, desarrollado principalmente por Williamson, se formula como una función tobit que se estima con datos de la industria del vino...
Article
Although economists have expended enormous effort examining the rationale for the contracts in agriculture, few studies have been undertaken in viticulture. However, in grape and wine production we observe different contractual arrangements. The underlying contractual structures are analyzed in different viticulture regions. Irrespective of the mod...
Article
The use of contracts to coordinate the relationship between a grape grower and a winery has become common practice in DOC Rioja. In this paper, the role and the characteristics of contracts in coordinating the supply of grapes between independent wine grape growers and wineries in DOC Rioja is examined. A review of existing theories on contractual...
Article
Full-text available
This paper provides an analysis of the choice of governance mechanism in agriculture using an integrated perspective based on agency theory. The main ways of organizing agriculture are compared: spot market and incentive contract. With the analytical development of both models, it is explored that the choice of the optimal mechanism depends on init...
Article
Full-text available
The possible co-existence of spot and contract market that can emerge in the presence of quality issues with a number of growers and processors in each stage is something that has largely remained an open question in the literature. This paper is an attempt to fill this void. We use a straightforward two-stage Cournot oligopoly model with specific...
Article
Full-text available
This paper develops a double-sided moral hazard model of share contract in agriculture, with imperfect quality measurement by the agent and the principal, who contribute to the final good quality in terms of production effort and marketing effort respectively. Using this model, we analyse the implications of the share contract for quantity and qual...
Article
Full-text available
We analyze the relationship between product quality and governance mode choice using the results of a survey of DOC Rioja wineries. Wineries that produce high-quality wines are more likely to vertically integrate than are wineries that produce low-quality wines. Consistent with Transaction Cost Economics, we find evidence that asset specificity and...
Article
Full-text available
A pesar de que los economistas han dedicado enorme esfuerzo a examinar la racionalidad de los contratos en agricultura, pocos estudios se han llevado a cabo en viticultura. Sin embargo, se observan diferencias contractuales en la producción de uva y vino. En el presente trabajo se analizan las estructuras contractuales actualmente utilizadas en var...
