Minimum consumption and transitional dynamics in wealth distribution

This paper investigates the evolution of wealth distribution in a one sector growth model along its transition path. A key feature of the model is that a household's consumption cannot fall below a positive level each period. This requirement introduces a positive association between the intertemporal elasticity of substitution and household wealth. Households only differ in their initial holdings of capital. The model is calibrated to match some key statistics of the US economy. The level of inequality in the wealth distribution of our artificial economy has a n inverted Ushape. The level of wealth inequality and its evolution resembles that of the US economy. However, our model illustrates that the existence of a Kuznets curve is very sensitive tothe sources of growth: whether it is driven by productivity growth or capital accumulation. Additionally, our model predicts an upsurge in wealth inequality following the productivity slowdown in the 1970's

LAGGING BEHIND VERSUS ADVANCING TOO FAST? IDENTIFYING GAPS RESEARCH IN SUPPLY CHAIN

The objective of our work is to analyze the evolution and actual trends of research in Supply Chain Management (SCM). We pretend to show how the different topics have been methodologically studied, and to determine how the advent of the so-called ‘New Economy’ has influenced SCM research. To get this objective, we carry out a literature review of twelve refereed journals in the Operations Management (OM) area for the period 1995-2001. Statistical tools are used to analyze the obtained information.

Environmental operations strategies: European approaches and research challenges

Since the environment has very recently emerged as a strategic issue, work has only begun to investigate the conceptual linkages between strategic management and the environment. A thoroughly revision of both academic and professional literature evidences that such scarcity of research doubles, or even trebles, when the scenery of the European Operations Management Strategies is considered. The main objective of this paper is, therefore, to discuss the impact of the design of the environmental management strategy on the formulation of the Operations Strategy and its implementation. Since the majority of the literature has neglected to focus the European approaches to such formulation, we will try to overcome this gap by analysing a sample of 2882 European companies

An integrated typology of green manufacturing profiles

This article proposes a typology to classify the Environmental Operations Strategies that the European Companies develop in order to adapt themselves to the requests of their green stakeholders. First, main research lines in Environmental Operations Management are analyzed; second, a typology based on the coherency of different variables that have been considered separately by other authors is presented and validated for a sample of 3051 European manufacturing companies. The results show that European manufacturers have not achieved yet similar levels of integration of the environmental concern into all managerial functions with the aim of reaching a sustainable balance between economic and ecological performance of the firm. Consequently, conventional typologies looking at different environmental criteria in a piecemeal fashion seem to be no longer valid for explanatory and/or decision making purposes

Buyer-supplier relationships influence on traceability implementation in the vegetable industry

The increasing importance of food safety has made traceability a crucial issue in the agri-business industry. In this article, we have analysed the factors that shape the buyer-supplier relationships, and how they influence the traceability of raw materials. In order to do so, first, we have made a literature review to develop an analytical framework. Next, we have carried out four case studies on vegetable firms with the purpose of uncovering the variables that characterise buyer-supplier relationships, and its influence on traceability in this sector. Finally, we have compared the observed links with the conceptual framework derived from the literature in order to build and improved model

Recorrido por los clásicos de la paranoia y reflexiones nosológicas que de este dimanan : paranoia i esquizofrenia (I)

Este recorrido por los clásicos de la paranoia incide en los autores que han aportado con sus investigaciones luz sobre la opacidad de las psicosis paranoicas. Por él desfilan psiquiatras germanos, franceses, y el conspicuo doctor Sarró, así como el genial S. Freud y su actual revalorizador, el doctor J. Lacan. Se trata de un recorrido por los clásicos, es decir, por los creadores y forjadores de lo que actualmente es un grupo nimio de psicosis, pero que en un tiempo fue la reina de las locuras.This review of the classics ofparanoia pinpoints the authors who, by their research, have contributed towards clarifying the opacity of paranoid psychoses. Among these are German and French psychiatrists, including the illustrious Dr. Sarró, the genial S. Freud and his present-day reviver, Dr. J. Lacan. The study concerns the creators and forgers of what is nowadays a small group of psychoses but which, in its day, was the most serious form of madness

Performance Measurement Systems, Competitive Priorities, and Advanced Manufacturing Technologies: Some Evidence from the Aeronautical Sector

Purpose – When acquiring advanced manufacturing technologies (AMT), the greatest caution should be taken regarding the performance measurement system to be used: the decision regarding new investments should not be conditioned by the excessive use of financial indicators to the detriment of the strategic objectives that motivated the investments. It is intended to analyze the aeronautical sector, for which the purchase of AMT is qualifying criteria, with two intentions: first, to identify the performance measurement systems that are used, and second, to test their correspondence with the objectives that motivated the investments. Design/methodology/approach – A survey of the 20 plants in the population was conducted via a postal questionnaire plus a structured interview. The unit of analysis has been maintained through the triangulation of data sources. Findings – The findings suggest that both financial and non-financial indicators are used, with the latter gaining predominance over the former on some occasions, even though there is no clear correspondence between strategy and the measurement of performance. In the light of the findings, the question of what inspires a company’s performance measurement system is still open, especially in those cases where there is no explicit strategy. With regard to practical implications, what seems to be indispensable is an improvement in the determination of the critical variables that should be used to measure performance. Research limitations/implications – Being valuable for academics and practitioners, this contribution relies, rather, on the possibility of a logical extrapolation to circumstances where the findings might apply, and researchers can judge whether the particular findings would be valid. Originality/value – Provides new evidence on the adaptation of the make-up and combination of the type of performance measures currently used by plants in the aeronautical industry, one of the sectors in which technological innovation is of the utmost importance.Publicad

Long and short-term effects of customisation on the service operations strategy.

This study has a twofold objectivc. First, we attempt to promote an understanding of the relationship between the design of Service Operations Strategics and their implementation, as they are driven by the customisation efforts. Seeond, we study the extent to which such service orientation may have two different forms, depending upon whether a company focuses on services that may have long-term or short-term effects on the customer nature. Consequently, a company aiming at raising its quality levels, and therefore its performance, should design and implement its Service Operations Strategy, mirroring the scrvicc oricntation of the firm. We suggest four dimensions (Time, Space, Scale and Scope), which contribute towards explaining the two mentioned approaches. This may address the process of implementation of the Serviee Operations Strategy.service operations; operations strategy; new service development process; marketing / operations interface; service-positioning matrix; customisation; service quality;

Stakeholders’ environmental influence. An empirical analysis in the Spanish hotel industry

We draw on the insights of stakeholder theory to explore the extent to which environmental management practices are driven by (i) an attempt to enhance a firm’s legitimacy, and (ii) a response to pressures arising from powerful stakeholders. The material for this investigation has been gathered from a sample of 279 Spanish hotels. The hotel industry which is only marginally affected by environmental regulation and is thus a widely neglected setting in this context, could be a particularly interesting subject for investigation, able to throw some light on the extent to which firms produce different responses to the environmental concerns of their stakeholders. Our results reveal that corporate environmental management practices may be a response to genuine environmental concerns, and we then speak of explicit environmental management, or there may also be reasons different from the environmental, in which case we speak of tacit environmental management. Our findings suggest that explicit and tacit environmental management account for a variety of organizational responses to the environmental demands of stakeholders, depending on (i) the stakeholders’ power regarding environmental issues, (ii) the stakeholders’ use of power to protect the environment, and (iii) the perceived economic advantages of environmental management activities.Publicad
