Accessing and producing tissue cultured banana plantlets in Costa Rica and Jamaica: Insights on the distributive consequences of emerging technologies

This paper analyzes the distributive dynamics associated with production, access to, and use of tissue-cultured banana plantlets in Costa Rica and Jamaica. In particular, it studies the research, commercialization, and production strategies undertaken in these two countries. It identifies the actors involved, the mechanisms implemented to produce and improve access to tissue cultured plants, as well as barriers to broad-based adoption. The discussion is framed by the concept of absorptive capacities and more particularly, by a revised perspective that differentiates between potential and realized capacities. In so doing, it emphasizes the dynamic aspects behind the process of moving from potential to realized capacities. Inherent aspects of tissue culture technology overlap and interact with socio-economic conditions; and become key to the dynamics of knowledge advancement, production, and distribution of benefits. In this context, policy choices play a major role in directing the dynamics towards a more distributed technological development.     

On strategic complementarity conditions in Bertrand oligopoly

Summary. For Bertrand duopoly with linear costs, we establish via a single (counter-)example that: (i) A new monotone transformation of the firms' profit functions may lead to the supermodularity of transformed profits when the standard log and identity transformations both fail to do so, and (ii) Topkis's notion of critical sufficient condition for monotonicity of a Bertrand firm's best-reply correspondence cannot be extended to rely only on positive unit costs.

Capital regulation, bank competition, and financial stability

We analyze capital requirements if banks compete for loans and deposits. Banks and firms are subject to a risk-shifting problem. The ambiguous effect of competition on banks’ risk-taking translates into an ambiguous effect of capital requirements on financial stability.     

Building ambidexterity: The role of human resource practices in the performance of firms from Spain

Both researchers and managers are increasingly interested in how firms can pursue ambidextrous learning—that is, simultaneously exploring new knowledge domains while exploiting current ones. In this study, we attempt to bring human resource management into this forum by introducing and testing how high‐involvement human resource practices shape the social climate that affects the firm's ambidextrous learning and subsequent performance. A field study of 198 companies from Spain showed that high‐involvement human resource practices were positively related to the social climate that, in turn, facilitates ambidextrous learning and improved performance. © 2012 Wiley Periodicals, Inc.     

THE 2007–2008 U.S. RECESSION: WHAT DID THE REAL‐TIME GOOGLE TRENDS DATA TELL THE UNITED STATES?

In the extant literature of business cycle predictions, the signals for business cycle turning points are generally issued with a lag of at least 5 months. In this paper, we make use of a novel and timely indicator—the Google search volume data—to help to improve the timeliness of business cycle turning point identification. We identify multiple query terms to capture the real‐time public concern on the aggregate economy, the credit market, and the labor market condition. We incorporate the query indices in a Markov‐switching framework and successfully “nowcast” the peak date within a month that the turning occurred. (JEL E37, G17)     

An application of co-word analysis and bibliometric maps for detecting the most highlighting themes in the consumer behaviour research from a longitudinal perspective

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield, concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR. It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future research could lead.     

Responding to Digital Transformation by External Corporate Venturing: An Enterprising Family Identity and Communication Patterns Perspective

Digital transformation increasingly requires activities located outside firm boundaries, for example via alliances with start‐up companies. Despite this, German Mittelstand firms, primarily owned and managed by enterprising families and seen as role models of innovation, appear reluctant to place strategic emphasis on venturing outside the firm’s boundaries when it comes to digital transformation. Drawing on the concepts of identity and communication patterns, we theorize on the mechanisms behind this behaviour. Applying structural equation modelling to a sample of 254 members of the next generation in enterprising families from Germany, we find that family communication patterns impact the strategic priority for or against external corporate venturing via identity‐related considerations.     

Promotion and Coevolutionary Dynamics in Contemporary Capitalism

We characterize the dynamics of contemporary capitalist societies as emerging from the coevolution of five different subsystems: the intimate realm of individuals, the market, the state, civil society, and nature. We highlight a specific coevolution mechanism between some of these subsystems, which we call promotion. The insights from this coevolution approach are twofold. On one hand, from the ontological and heuristic perspectives, we argue that our proposal opens the possibility for constructing a general, interpretative framework in evolutionary economics. On the other hand, from a theoretical-explanatory perspective, we detect certain coevolution paths that may engender global pathologies in capitalist societies. We also suggest that future research may explore some normative implications of this approach, as well as alternative methodological strategies to develop it.     

Growth,Convergence, and Social Cohesion in the European Union

The aim of this paper is to analyze the economic and social cohesion in the European Union. There are different factors to explain the convergence process and besides, empirical findings are not conclusive. To the European Union, GDP per head interregional differences have decreased for certain periods but it has remained unchanged or even increased for others periods. The second report on the economic and social cohesion indicates that some decades are necessary to eliminate regional differences. These differences in regional GDP are mainly explained by differences in their productive structures, degree of innovate activity, communications structures, which depend on the relative level of transport infrastructures, and manpower qualifications. This analysis allows us to obtain some conclusions to the economic policies and the social cohesion. A preliminary version of this paper was presented in the 57th International Atlantic Conference, held in Lisbon, Portugal, March 10–14, 2004.
