POLICY MAKING FOR INDUSTRIAL COMPETITIVENESS IN PORTUGAL - Patterns of change in a traditional bureaucracy

In Portugal the EEC membership represented a major change in Portuguese Administration functioning. This article uses the new institutionalism approach and the concept of path-dependence to analyse the change in the functioning of a central directorate reponsible for industrial policy. It argues that despite the external pressures for change has altered the directorate operations, there are patterns of continuity which are path-dependent. The response to change shows institutional reproduction in traditional features which is partly due to the reluctance to change traditional methods and partly because of the routines, procedures and norms embedded in the culture.     

Repeated Dichotomous Choice Formats for Elicitation of Willingness to Pay: Simultaneous Estimation and Anchoring Effect

Repeated dichotomous choice contingent valuation data are generated from responses to a succession of binary questions regarding alternative prices for an environmental good. In this paper we propose a simultaneous equation model that allows for endogeneity and error correlation across the responses at each stage of the bidding process. The model allows us to study the evolution of anchoring effects after the second dichotomous choice question. Estimation involves the Bayesian techniques of Gibbs sampling and data augmentation, and the application focuses on the preservation value of a natural area. The results for a data set involving up to four successive dichotomous choice questions show that restricted multiple-bounded models are rejected by the data with the general model. In addition, willingness to pay tends to stabilize after the second stage in the elicitation process for the general unrestricted model. When taking anchoring effects into consideration, it is revealed that individuals’ responses in the latter stages are influenced by the sequence of bid prices offered in earlier questions. Nevertheless, they do not have a significant effect on welfare estimates.      

A proposed method to evaluate the quality of services using Fuzzy sets theory

This paper seeks to provide the services sector with a focus on the assessment of quality and for this purpose, a technique that may able a quantitative approach to evaluating quality is proposed. The use of the fuzzy sets theory to process data was used, thus allowing a more flexible and suitable insight into the characteristics of the service sector. An extension of the technique for order performance by similarity to the ideal solution was used. This informs managers of the distance from the company $\prime $ s current level of quality, if compared to a company of perfect quality by means of an overall evaluation. The same technique was used to detect changes in the level of quality during the period surveyed by using a stratified assessment. Finally, a practical application of the approach proposed is presented.     

What's Behind CRM Research? A Bibliometric Analysis of Publications in the CRM Research Field

The diversity of approaches to customer relationship management (CRM) brings about the need for systematic reviews. The objective of this article is to identify and categorize the most used publications in the CRM field. We conducted a bibliometric analysis using the Web of Science database. To identify and categorize the subfields, we conducted an exploratory factor analysis. The most used publications were categorized into: (1) methodology in the CRM research field; (2) relationship marketing; (3) service quality and customer loyalty; (4) implications of market-oriented strategy; (5) CRM theory and its practical implications; (6) strategic management; and (7) customer value.     

Regulating collateral-requirements when markets are incomplete

In this paper we examine the effects of default and collateral on risk sharing. We assume that there is a large set of assets which all promise a risk less payoff but which distinguish themselves by their collateral requirements. In equilibrium agents default, the assets have different payoffs, and there are as many linearly independent assets available for trade as there are states of the world. We derive necessary and sufficient conditions for equilibria to be Pareto-efficient in the presence of uncertainty. We explore some examples for which the collateral equilibrium allocation is identical to the Arrow–Debreu allocation, either when agents have a high preference for the durable good, or when the endowment distribution of the durable good is relatively homogeneous. We examine a series of examples to understand which collateral-levels prevail in equilibrium and under which conditions there is scope for regulating margin-requirements, that is, restricting the sets of tradable assets through government intervention. In these examples equilibrium is always sub-optimal but regulation never leads to a Pareto-improvement. While the competitive equilibria are constrained efficient, there do exist regulations which make large groups of agents in the economy better off. These regulations typically restrict all trades to take place in the low-collateral loans and benefit the poor and the rich agents in the economy through their effects on the equilibrium interest rate and the equilibrium prices of the durable goods.     

On positional consumption and technological innovation: an agent-based model

Positional behaviour is arguably a source of social externalities. Remedies for this market failure are defended by some authors and rejected by others. One of the issues discussed is the role that the competition for positional goods may have in generating technological innovation. This article aims to contribute to the understanding of the dynamics of this process through the use of an agent-based model. Simulations show a plausible dynamics of the process of technological innovation as generated by consumption of positional nature. An interpretation of the results in the scope of the policy discussion in question is provided. The influence of key factors such as income inequality, the materialization of the Hirsch conjecture, and characteristics of the network of relative preferences, is analised. We also frame the potential interest of positional consumption and this model in particular in the context of the ongoing discussion among evolutionary economists on the behaviour of demand.     

The Role of Environmental Management in Consumers Preferences for Corporate Social Responsibility

Consumers in modern societies are increasingly sensitive to environmental performance by large and small corporations, making it a crucial issue in the overall policy of corporate social responsibility. The objective of this paper is to study the role of environmental performance in the profile of corporate social responsibility as perceived by consumers. We utilize a stated preference approach to the study of consumer’s preferences. This approach allows for the evaluation in monetary terms of the trade-offs that individuals can make between various aspects of corporate policy decisions, including the extent of environmental performance. The data is modelled by means of a mixture heuristics approach that allows us to study the utilization of various decision rules in the choice of products with various degrees of environmental performance. The results show that the linear compensatory heuristic is the most extended across individuals and these subjects value most the policies concerned with environmental management. Those subjects opting for the non-compensatory decision rule tend to focus on the attribute of good labour relations as the most salient factor defining corporate social responsibility. In addition, policy measures are relatively more valued for some products rather than for others, suggesting that consumers discriminate between products when valuing companies’ environmental profiles.     

The geometry of crashes. A measure of the dynamics of stock market crises

This paper investigates the dynamics of stocks in the S&P 500 index for the last 30 years. Using a stochastic geometry technique, we investigate the evolution of the market space and define a new measure for that purpose that is a robust index of the dynamics of the market structure and provides information on the intensity and the sectoral impact of crises. With this measure, we analyse the effects of extreme phenomena on the geometry of the market. Nine crashes between 1987 and 2001 are compared by looking at the way they modify the shape of the manifold that describes the S&P 500 market space.     

Country size,technology, and Ricardian comparative advantage

We develop a Ricardian model with heterogeneous firms in which country size and technology play a crucial role in the firm‐level variables. We show that a country with larger size and better technology exhibits higher productivity and lower price–cost margins even under assumptions of C.E.S. preferences and monopolistic competition. Welfare is higher in this country, not only due to the increased product variety but also due to increased competition in a domestic market. We also show that country size and technology impact critically on the intensive margin as well as the extensive margin in the gravity equation.     

Scale-perception bias in the valuation of environmental risks

The valuation of environmental risks is commonly approached with the utilization of stated preference methods such as contingent valuation. In these methods, money is utilized as the scale that reflects the individual's underlying utility function. However, this scale can vary across individuals due to different perceptions on what are the right or appropriate bounds for Willingness To Pay (WTP). In this article, we test for scale-perception bias and propose a correction method based on the utilization of anchoring vignettes that define different degrees of preference for the nonmarket good. The proposed method is applied to study the commonly found anomaly ‘probability neglect’, which is defined by the insensitivity to the probability levels in the valuation of environmental risks. The results show that probability neglect disappears when WTP responses are corrected for self-perception bias through the utilization of the anchoring vignettes approach.
