The Contribution of Bioenergy to a New Energy Paradigm

Biomass is a widely available resource that is receiving increased consideration as a renewable substitute for fossil fuels. Developed sustainably and used efficiently, it can induce growth in developing countries, reduce oil demand, and address environmental problems. The potential benefits include: reduction of greenhouse gases, recuperation of soil productivity and degraded land, economic benefits from adding value to agricultural activities and improving access to and quality of energy services. The production of bioenergy involves a range of technologies, including solid combustion, gasification, and fermentation. These technologies produce energy from a diverse set of biological resources - traditional crops, crop residues, energy-dedicated crops, dung, and the organic component of urban waste. The results are bioenergy products that provide multiple energy services: cooking fuel, heat, electricity and transportation fuels. It is this very diversity that holds the potential of a win-win-win for the environment, social and economic development. Bioenergy has to be viewed not as a replacement for oil, but as an element of a portfolio of renewable sources of energy. Coherent and mutually supportive environmental and economic policies may be needed to encourage the emergence of a globally dispersed bioenergy industry that will pursue a path of sustainable development.     

A NEW MULTIPLICATIVE DECOMPOSITION FOR THE FOSTER–GREER–THORBECKE POVERTY INDICES

This paper shows that Foster–Greer–Thorbecke poverty indices can be written as the product of components summarizing the incidence, intensity and inequality dimensions of poverty and provides an empirical illustration of the decomposition using Spanish household budget surveys data.     

Modelling the propagation of adult male muscle dysmorphia in Spain: economic,emotional and social drivers

Males aged over 40 do more gym practice to improve their body image as a way of reinforcing their personal self-esteem and sexual appeal. Cases when self-image becomes an obsession may result in a body dysmorphic disorder named ‘muscle dysmorphia’ (MD). The combination of psychological, environmental and biological drivers determines the appearance and development of this disorder. In this article, we developed a discrete population mathematical model to forecast the rate of prevalence of males who are noncompetitive bodybuilders at risk of suffering MD in Spain in forthcoming years. Economic, emotional, sociological and psychological motivations were taken into account to quantify the dynamic behaviour of Spanish noncompetitive bodybuilders. The impact of the unemployment is reflected in the construction of two coefficients, α_u and α₂₁, which explain subpopulation transits due to the economy. Sociological influences, such as human herding and social propagation, were also considered. Our results predict an increase in Spanish noncompetitive bodybuilders suffering MD from 1% in 2011 to around 11% in 2015. Our model can be applied to any other western country where data are available and to another study period when the hypotheses are applicable.

Consequences of Economic Partnership Agreements between East and Southern African Countries and the EU for Inter- and Intra-regional Integration

Abstract

The European Union is currently negotiating Economic Partnership Agreements (EPAs) with six African, Caribbean and Pacific country groupings, aiming at establishing mutual free trade. This paper empirically assesses the impact of the EPAs on trade flows and government revenues for 22 East and Southern African countries and discusses implications for intra-regional integration. The results indicate that while moderate trade effects can be expected, relatively large budget effects are likely to occur in a number of these countries, exposing them to considerable structural and financial adjustment requirements. In addition, EPAs would strengthen the need to consolidate overlapping intra-regional integration schemes.     

Strategic orientations and new product commercialization: mediator,moderator, and interplay

Why are some firms more successful at commercializing new products than others in emerging economies? It is possible that the strategic orientations, which firms adopt as a type of business strategy, lead at least partially to the superior performance of the new products they introduce to the market. Strategic orientations facilitate a match between firm strategy and resource endowment, on the one hand, and the adaptation to market conditions, on the other. In this paper, we empirically test whether four major types of strategic orientations (market orientation, technology orientation, entrepreneurial orientation, and networking orientation) are simultaneously related to new product commercialization performance using data collected from China. We find that strategic orientations are positively related to three aspects of new product commercialization, namely new product advantage, new product newness, and number of new products introduced to the market. Interestingly, we find that pairs of strategic orientations support each other in exerting their impacts on new product commercialization performance. In addition, we find that organizational learning mediates the effects of strategic orientations on new product commercialization and that environmental dynamism moderates the effect of strategic orientations on new product commercialization. We obtain the valuable insight that a firm's successful commercialization of new products hinges upon the development of critical yet complementary sets of strategic orientations, especially in a dynamic business environment.     

Organizing for Inbound Open Innovation: How External Consultants and a Dedicated R&D Unit Influence Product Innovation Performance

Firms increasingly acquire technological knowledge from external sources to improve their innovation performance. This strategic approach is known as inbound open innovation. The existing empirical evidence regarding the impact of inbound open innovation on performance, however, is ambiguous. The equivocal results are due to moderating factors that influence a firm's ability to acquire technological knowledge from external sources and to transform it into innovation outputs. This paper focuses on a relevant yet overlooked category of moderating factors: organization of research and development (R&D). It explores two organizational mechanisms: one informal and external‐oriented (involvement of external consultants in R&D activities) and one formalized and internal‐oriented (existence of a dedicated R&D unit), in the acquisition of technological knowledge through R&D outsourcing, a particular contractual form for inbound open innovation. Drawing on a capabilities perspective and using a longitudinal dataset of 841 Spanish manufacturing firms observed over the period 1999–2007, this paper provides a fine‐grained analysis of the moderating effects of the two organizational mechanisms. The involvement of external consultants in R&D activities strengthens the impact of inbound open innovation on innovation performance by increasing marginal benefits of acquiring external technological knowledge through R&D outsourcing. Moreover, it reduces the level of inbound open innovation to which the highest innovation performance corresponds. Instead, the existence of a dedicated R&D unit makes the firm less sensitive to changes in the level of inbound open innovation, by reducing marginal benefits of acquiring external technological knowledge through R&D outsourcing, and increases the level of inbound open innovation to which the highest innovation performance corresponds. The results regarding the role of informal and formalized R&D organizational mechanisms contribute to research on open innovation and absorptive capacity, and also inform managers as to what organizational mechanism is recommended to acquire external technological knowledge, depending on the objectives that the firm pursues.
