From production to sustainability: Considering the whole household

The recent focus on sustainability as guiding principle for economic activity has generated many, and often conflicting, definitions of sustainable economic development. Yet while the terminology may be new, the discussion is not. Rather it parallels the discussion about biases of economic measurement and valuation concepts which have led to the neglect of the domestic and subsistence contribution of female householdership relegated to the informal sector. This paper argues that the selective focus of economics on narrowly defined productive functions has led to the detrimental neglect of sustaining functions without which production itself would be impaired. Informed by feminist theory, three principles are identified which are essential to the conceptual framework of a sustainable production theory. They are: concretion rather than abstraction, connectedness rather than isolation, and diversity rather than homogeneity. Without deterring from the importance of gender (especially in economics), the discussion of these principles of a sustaining orientation of economics is viewed in a broader context of mind-sets. It is argued that to reframe the relationship between production and sustainability as compatible rather than adversarial requires a broadening of theory, inquiry, and methodology. The voices of women who have gone largely unheard in economics are essential in this refraining process.

Zusammenfassung Von der Produktion zur Nachhaltigkeit: Die Betrachtung des Haushalts als Ganzes. Die neuere Betonung der Nachhaltigkeit als Leitprinzip für ökonomisches Handeln hat zu vielen — manchmal uneinheitlichen — Definitionen der nachhaltigen wirtschaftlichen Entwicklung geführt. Neu ist bei dieser Diskussion nur die terminologische Seite, die inhaltliche ist es nicht. Vielmehr gleicht sie der Diskussion über unzulÄngliche Konzepte zur ökonomischen Messung und Bewertung, die zu einer VernachlÄssigung des dem informellen Sektor zugeordneten Unterhaltsbeitrages der überwiegend weiblichen haushÄlterischen TÄtigkeit geführt hat. Der vorliegende Beitrag will zeigen, da\ die einseitige Betonung eng definierter produktiver Funktionen durch das ökonomische Denken zu einer schÄdlichen VernachlÄssigung der Unterhaltsfunktionen geführt hat, ohne die die Produktion sehr beeintrÄchtigt wÄre. Ausgehend von feministischer Theorie werden drei Prinzipien identifiziert, die für eine Theorie nachhaltiger Produktion wichtig sind: Konkretisierung statt Abstraktion, Verbundenheit statt Isolation und Verschiedenheit statt Einheitlichkeit. Wenn Produktion und Nachhaltigkeit in neuer Sichtweise nicht mehr nur als gegensÄtzlich, sondern als miteinander vereinbar gesehen werden sollen, so ist dafür eine Ausweitung der Fragestellungen der Theorie und der Methodologie notwendig. Die Stimmen der in der ökonomik weitgehend ungehörten Frauen sind für diese neue Sichtweise sehr wichtig.

     

Critical success factors determining performance of cross‐border acquisition: Evidence from the African telecom market

This study investigates the factors affecting Bharti Airtel's cross‐border postacquisition performance in an African market. This study describes the relationships among various factors such as technical capability, affiliated firm's absorptive capacity, and organizational learning capabilities, which determine the successful operations of the Zain acquisition deal in South Africa. This paper adopts a qualitative approach to identify factors that influence the postacquisition performance. Seven factors are identified based on the literature. Consequently, it has become a necessity to encapsulate these factors in suitable proportions. In this study, we have developed a total interpretive structural modeling (TISM) to analyze the postacquisition performance of Bharti Airtel in South Africa. Our research has highlighted six dynamic factors (organizational learning capability, knowledge management, technology capability, technology relatedness, acquirer's absorptive capacity, and national culture difference) that affect the firm's postacquisition performance. The interpretive structural model (ISM) and total interpretive structural model for postacquisition performance are built‐up. The developed TISM will support academics and practitioners to develop their understanding of acquisition performance of parent companies in the context of telecom business in the South African market.     

Varying Coefficient Regression Models: A Review and New Developments

Varying coefficient regression models are known to be very useful tools for analysing the relation between a response and a group of covariates. Their structure and interpretability are similar to those for the traditional linear regression model, but they are more flexible because of the infinite dimensionality of the corresponding parameter spaces. The aims of this paper are to give an overview on the existing methodological and theoretical developments for varying coefficient models and to discuss their extensions with some new developments. The new developments enable us to use different amount of smoothing for estimating different component functions in the models. They are for a flexible form of varying coefficient models that requires smoothing across different covariates' spaces and are based on the smooth backfitting technique that is admitted as a powerful technique for fitting structural regression models and is also known to free us from the curse of dimensionality.

Comparing levels of resident empowerment among two culturally diverse resident populations in Oizumi,Gunma, Japan

While resident empowerment has been a central aspect of the sustainable tourism literature, difficulties of putting the concept into practice have been noted given the heterogeneous nature of communities. “Community” is often divided by kinship, age, gender and ethnicity, and such division may influence the perceptions of empowerment. The goal of this study was to better understand heterogeneous perceptions of empowerment by administering the Resident Empowerment through Tourism Scale within the community of Oizumi, Japan. Oizumi has the highest concentration of Brazilian immigrants in Japan, and the town has embraced “ethnic neighborhood tourism” centered on Brazilian culture as a strategy for economic development. Oizumi's demographic makeup allowed for testing differences in perceived empowerment between members of the dominant ethnic group (Japanese) and members of the ethnic minority group (Japanese Brazilians). Analysis of 650 completed questionnaires revealed that Brazilians felt more psychologically and socially empowered than Japanese residents, indicating a shift in the balance of power between the ethnic groups. Results also revealed that the political dimension of empowerment was rated relatively low among both groups, suggesting a general lack of opportunities to participate in the planning process. Implications for both practice and theory are presented.     

TV viewing: application of a formal choice model

Choices of television programs is viewed as a process of deciding among a set of alternative goods with zero prices. A choice model can thus be based purely on individuals' preferences for various characteristics of a set of shows available, incorporating the option of not watching if all shows are too dissimilar to these desires. The shows are first grouped according to salient characteristics and a preferred value for each characteristic is estimated for each potential viewer. A perceived position of each show is similarly estimated and watching is shown to decline as similarity between preferred show and available alternatives declines. The choice model predicts show choice better than simpler models based on aggregate audience measures or on network loyalty, but the explanatory power is weak; some suggestions for improvement are made.

Prepayment and future cross-buying: an exploratory analysis

Recent research has provided important insights on consumers’ preferences for prepayment mechanisms and on its impact on consumption of a given product or service. However, little is known about how prepayment influences future purchases of goods and services. We consider this question in a contractual setting within the services industry, involving different purchasing decisions over time. Based on a large-scale empirical test, we find that prepay customers make fewer changes to their cross-buying levels (i.e., the number of different services they buy from the company) from one contractual period to another, and that this effect is more salient for the firm's new customers. We propose possible explanatory mechanisms for this effect. For instance, based on mental budgeting theory, we suggest that prepayment customers may set mental budgets and track expenditures against this budget leading them to resist further investments. Alternatively, prepayment customers may be more certain about their consumption behavior leading to fewer changes over time.
