Economic and agricultural development in West Asia and North Africa : The need for agricultural research

This paper analyses the role of agriculture in the economic development of West Asia and North Africa, with special reference to the interactions between oil wealth, population growth, agricultural development and the need for agricultural research. Since the 1960s agricultural supply lagged behind demand, which grew rapidly as a result of population increases and rising incomes. Following the oil recession of the 1980s it was felt that the development of the agricultural sector should be less dependent on other sectors, particularly oil. The possible roles of agriculture in the region's future economic development are outlined, with the implications for agricultural research. Special attention is given to the natural resource constraints affecting the region's agriculture (particularly water), and to the issues influencing the identification of research priorities.     

Class practices of dwellers in barrios populares: the struggle for the right to the city1

La résistance des habitants des quartiers populaires de Bogotá contre la construction d'une autoroute à travers leur voisinae, est le sujet de cet article. Cette 'Avenida de los Cerros' faisait partie d'un 'programme intégré de développement urbain' comprenant aussi la construction de centres médicaux, écoles, et autres infrastructures urbaines; le côut de 89 millions de dollars américains, étant financé par l'Intramerican Development Bank. Ce mouvement urbain est analysé en tant que pratique spécifique, particulière aux résidents des quartiers populaires. En tant que groupe sociale, leurs traits communs sont qu'ils vivent à l'intérieur d'un quartier strictement ségrégé géographiquement et socialement—le 'barrio', et qu'ils vendent leur force de travail sur un marché du travail dévalué, sans pour autant constituer une classe sociale homogène. Toutefois, comme sous-proletariat urbain ils partagent un intérêt commun dans la consommation collective et individuelle (déficiences en matières de logement, service, etc., et expérience de la pauvreté). La menace de l'Avenida de los Cerros dans ces deux domaines fût reconnue et causa une grande agitation parmi les habitants du 'barrio'. Le plan de construction fût abandonné après deux ans de protestations. Bien que le mouvement populaire eu de l'influence, cet abandon fut en grande partie causé par une conjoncture changeante quand les intérêts du bloc au pouvoir de la classe dirigeante se déplacèrent vers d'autres quartiers.     

Rate of convergence in the central limit theorem and in the strong law of large numbers for von mises statistics

This paper provides the rate of convergence in the central limit theorem and in the strong law of large numbers forvon Mises statistics , based on i.i.d. random variablesX ₁ ,..., X _N .The proofs rely on a decomposition ofvon Mises statistics into a linear combination ofU-statistics and then use (generalized) results on the convergence rates forU-statistics obtained byGrams/Serfling [1973] andCallaert/Janssen [1978].     

Occupational Stereotypes and Gender‐Specific Job Satisfaction

Using representative data containing information on job satisfaction and workers’ gender‐specific prejudices, we investigate the relationship between stereotyping and job satisfaction. We show that women in stereotypically male jobs are significantly less satisfied with their work climate and job content than in stereotypically female jobs but more satisfied with their income in those same jobs. Our findings indicate that women trade off their higher income satisfaction against the negative consequences of stereotyping. As long as we take into account that stereotypically male jobs are physically more demanding than stereotypically female jobs, men are generally more satisfied with stereotypically male jobs.     

Triple play: How do we secure future benefits?

Recent technological developments make it possible to provide all telecommunications services (TV, telephony and internet) via the TV cable and fixed telephony network. Moreover, a new infrastructure based on optical fibre (to the home) is emerging in some places, which may in the future replace both existing networks. Making use of the available economic literature, the paper analyzes some of the consequences of the emergence of one electronic communications market. It focuses on two policy issues: the consequences of convergence of technologies and competition between networks for regulation in the short and medium runs, and the role of public investment in the rollout of optical fibre. It concludes that the present state of regulation may have some undesirable effects in the face of convergence and that public investment in a new general purpose infrastructure may have important advantages.     

Negative Strompreise und der Vorrang Erneuerbarer Energien

With the appearance of negative prices a discussion about flaws in the design of the German electricity market arose. We show that negative prices are not only due to the integration of electricity from renewable energy sources. Negative prices can actually increase welfare. Yet, a loss of welfare does arise because of the priority feed-in of these sources. They are inclined to deliver energy even when the cost of production exceeds the market price, i.e. the electricity’s value. We suggest to remove the priority feed-in combined with a modification of the feed-in tariffs. Thereby, renewable electricity producers will suffer no drawbacks but social welfare increases.     

The Moderating Role of Tangibility in Synchronous Innovation in Services

A synchronous pattern of innovation as between technological and management innovation, for example, can help firms improve their performance. This article explores this idea with respect to servitizing companies that introduce service delivery innovation as a means of gaining competitive advantage. It finds that the degree of tangibility, an indicator of the firm’s position on the product–service continuum, affects whether and how managers recognize the need for management innovation when introducing service delivery innovation. Using a socio‐technical perspective in conjunction with insights from managerial cognition, the relationship between management innovation and two central types of service delivery innovation—technological and customer interface—is examined. Tangibility shapes the managerial cognitive structures that are related to the enterprise’s technical and social subsystems in a paradigm that is capable of demonstrating contrasting effects. Technological delivery innovation is related to management innovation in firms with high tangibility. Customer interface delivery innovation, on the other hand, relates to management innovation in firms with low tangibility. This study uses a sample of diverse firms with varying degrees of tangibility to provide support for this theory.     

What Happens Next? A Qualitative Study of Founder Succession in Social Enterprises

In the organizational context of social enterprises, the viability of the primary social mission is put to the test when the founder leaves the organization. Yet the literature has remained silent on this important stage in the life of a social enterprise. We address this gap by conducting in‐depth case studies in the unexplored setting of India. Based on multiple interviews, field observations and archival data, we develop insights into the significance of “social entrepreneur centrality” in social enterprise founder succession, discuss its consequences, and review the effects of contextual influences. Contributions to social entrepreneurship research and practice are discussed.
