Is the Current Regulation of the VIII Division European Anchovy Optimal?

This paper sets out to assess the workability of the regulation currently in force in the European anchovy fishery of the VIII division. Particular attention is paid to the importance of the institutional regime in the allocation of natural resources. The study uses a bio-economic approach and takes into account the fact that, not only the European Union and the individual countries involved, but also some of the resource users or appropriators intervene in its management. In order to compare the effectiveness of the rules which, at the various levels, have been set up to restrict exploitation of the resource, the anchovy fishery is simulated in two extreme situations: open access and sole ownership. The results obtained by effective management will then be contrasted with those obtained from the maximum and zero profit objectives related with the two above-mentioned scenarios. Thus, if the real data come close to those derived from the sole ownership model it will have to be acknowledged that the rules at present in force are optimal. If, on the other hand, the situation more closely approach the results obtained from the open access model, we will endeavour in our conclusions to provide suggestions for economic policy measures that might improve the situation in the fishery.     

On some criticisms of critical realism in economics

Methodological comments on critical realism in economics haveproliferated over the past decade—typically focusing onTony Lawson's Economics and Reality and Reorienting Economics,which constitute the core of this project. In the present paperwe select a series of important, mostly very recent argumentsagainst critical realism in economics and assess their meritsand demerits.     

Measuring Synchronization and Convergence of Business Cycles for the Euro area,UK and US*

This paper investigates business cycle relations among different economies in the Euro area. Cyclical dynamics are explicitly modelled as part of a time series model. We introduce mechanisms that allow for increasing or diminishing phase shifts and for time‐varying association patterns in different cycles. Standard Kalman filter techniques are used to estimate the parameters simultaneously by maximum likelihood. The empirical illustrations are based on gross domestic product (GDP) series of seven European countries that are compared with the GDP series of the Euro area and that of the US. The original integrated time series are band‐pass filtered. We find that there is an increasing resemblance between the business cycle fluctuations of the European countries analysed and those of the Euro area, although with varying patterns.     

Managing functional diversity, risk taking and incentives for teams to achieve radical innovations

In this study we analyse the effect of team diversity, encouragement to take risks and team incentives on the degree of radicalness of innovation. Empirical research has been conducted with a sample of 95 companies from four innovative industries according to their high number of patents. The results indicate that team diversity and the combined use of long- and short-term incentives are associated with incremental innovation, whereas the development of risk-taking attitudes within the team is associated with radical innovation.     

Understanding some recent existence results for discontinuous games

We introduce a new condition, weak better-reply security, and show that every compact, locally convex, metric, quasiconcave and weakly better-reply secure game has a Nash equilibrium. This result is established using simple generalizations of classical ideas. Furthermore, we show that, when players’ action spaces are metric and locally convex, it implies the existence results of Reny (Econometrica 67:1029–1056, 1999) and Carmona (J Econ Theory 144:1333–1340, 2009) and that it is equivalent to a recent result of Barelli and Soza (On the Existence of Nash Equilibria in Discontinuous and Qualitative Games, University of Rochester, Rochester, 2009). Our general existence result also implies a new existence result for weakly upper reciprocally semicontinuous and weakly payoff secure games that satisfy a strong quasiconcavity property.     

Revisiting the substantiality criterion: From ethnic marketing to market segmentation

This paper examines the meaning and application of the concept of substantiality for consumer market segmentation and target selection with a focus on ethnicity and minority ethnic groups. In contrast with interpretations of segment substance anchoring on some sufficient potential size to justify time and effort involved in planning, the objective is to consider key group dimensions to ascertain potential substantiality. Common criteria proposed to assess substance are essentially an exhortation to assess the value of the segmenting opportunity. An increase in producer surplus meets this requirement but this consideration is done post hoc. The challenge for market segmentation is to assess substantiality a priori. This paper presents a screening approach based on appraising minority ethnic group resources that enables such an assessment and has potential applicability to other consumer subcultures.     

Climate perceptions and the customer orientation of frontline service employees

Satisfaction of customers' needs is particularly dependent upon the customer orientation of frontline employees. Understanding the drivers of such orientation is, therefore, a key issue in current research. Research relating perceptions of organisational values with the customer orientation of employees is rather sparse. This topic is approached by investigating the role of selected dimensions of psychological climate in promoting the customer orientation of frontline service employees. A structural equations model is developed and empirically tested, indicating that perceptions of customer, ethical, and innovation climates exert an indirect effect on the adoption of customer-oriented behaviours by frontline employees.     

Management and Risk Characteristics of Part-Time and Full-Time Farmers in Norway

The objective of this exploratory study was to provide empirical insight into how different categories of farmers perceive and manage risk. The data originate from a questionnaire of dairy and crop farmers in Norway. The associations between part-time and full-time farming and farm and farmer characteristics, farmers' goals and future plans, risk perceptions, and risk management responses were examined with simple t - and chi-square tests, as well as with logistic regression. The results indicate that full-time and part-time farmers' goals, risk perceptions, and management strategies differ significantly. Policy makers and advisers should consider these differences when developing policies and recommendations for the different types of farmers.
