The Exercise of Moral Imagination in Stigmatized Work Groups

This study introduces the concept of moral imagination in a work context to provide an ethical approach to the controversial relationships between dirty work and dirty workers. Moral imagination is assessed as an essential faculty to overcome the stigma associated with dirty work and facilitate the daily work lives of workers. The exercise of moral imagination helps dirty workers to face the moral conflicts inherent in their tasks and to build a personal stance toward their occupation. Finally, we argue that organizations with dirty work groups should actively adopt measures to encourage their employees’ exercise of moral imagination. This study investigates how organizations might create conditions that inspire moral imagination, particularly with regard to the importance of organizational culture as a means to enhance workers’ moral sensitivity. Furthermore, this investigation analyzes different company practices that may derive from a culture committed to moral imagination.     

Ruin probabilities and optimal capital allocation for heterogeneous life annuity portfolios

A large part of the actuarial literature is devoted to the derivation of ruin probabilities in various non-life insurance risk models. On the contrary, very few papers deal with ruin probabilities for life insurance portfolios. The difficulties arise from the dependence and non-stationarity of the annual payments made by the insurance company. This paper shows that the ruin probability in case of life annuity portfolios can be computed from algorithms derived by De Pril (1989) and Dhaene & Vandebroek (1995). Approximations for ruin probabilities are discussed. The present article complements the works of Frostig et al. (2003) who considered whole life, endowment, and temporary assurances, and of Denuit & Frostig (2008) who considered homogeneous life annuities portfolios. Here, heterogeneous portfolios (with respect to age and/or face amounts) are studied. Particular attention is paid to the capital allocation problem. The total amount of reserve is shared among the risk classes in order to minimize the ruin probability. It is then fair to charge a higher margin to the risk classes requiring more capital.     

Economic impact of cruise activity: the case of Barcelona

ABSTRACT

This article shows the methodology and the main figures of the local and regional economic impact generated by cruise activity. This article is pioneering in combining different issues: estimating the impact of the cruise port activity, presenting these impacts disaggregated at a sectoral level, using a rigorous methodology and carrying out extensive fieldwork. It is demonstrated that all sectors, not just traditional tourism-related sectors, benefit from cruise tourism. In order to test and apply our methodology we focus the analysis on the Port of Barcelona, which has become the leading cruise port in the Mediterranean area.     

Regulatory regimes in the electric power industry: Implications for capacity

We construct a model of the electric power industry which consists of two utilities faced with uncertain demand and a variety of regulatory regimes. Two technologies are considered, base-load and peaking, and the transfer of bulk electricity among utilities is permitted. The purpose of the paper is not to determine optimal regulatory regimes but to provide a framework for analyzing existing and contemplated regulatory initiatives. The conclusions are that long run survival mandates an authorized rate of return above the cost of capital and that excess investment will result. Furthermore, it is highly unlikely that current regulatory instruments such as Used and Useful, distribution of profits from bulk sales, and pricing of wholesale electricity can lead to a socially optimal capital stock.     

University spillovers and new business location in high-technology sectors: Spanish evidence

This paper examines the relationship between knowledge spillovers from universities and new business location in high-technology sectors. We focus on the contribution to new business formation through spillovers stemming from three main university outputs: knowledge-based graduates, research activities, and technological knowledge. We construct a new dataset with information on 604 companies and 63 universities in Spain and group the data across 36 geographical areas from 2001 to 2004 (144 observations). After controlling for several traditional cost factors and agglomeration characteristics, we find that university spillovers are relevant in explaining the location of new businesses in high-technology sectors in Spain. Further, our analysis draws attention to the relevance of graduates as the main source of spillovers, while research activities and university technology do not have significant effects.     

Dynamic technological specialization,aggregated convergence and growth

This paper focuses on the contribution of dynamic technological specialization to aggregated growth and convergence. Certain theoretical approaches (Structuralism) maintain the view that being specialized in ‘correct’ technologies helps to achieve: i) sustainable rhythms of long-run growth; ii) accelerated catching up and higher rhythms of convergence in delayed countries. Using an endogenous growth model for a 23 countries sample between 1980 and 2010, the work contrasts those hypotheses by using static and dynamic approaches for technological specialization in comparison to other technological variables. Empirical results do not confirm that any ‘good’ specialization matters to growth and convergence at an aggregated level, neither under static nor dynamic approaches. The key elements to aggregated convergence and growth are more linked to spillovers of technological diffusion and to country-specificities (technological capabilities and capacities, domestic technical efforts, national innovation systems, industrial innovation processes, etc.) as it is pointed out by catching-up theories.     

Stereotypical Notions of the Entrepreneur: An Analysis from a Perspective of Gender

The principal objective of this paper is an analysis of the stereotypical figure of the entrepreneur in the Spanish context, from a perspective of gender. We provide evidence that the characteristics largely associated with an entrepreneurial individual are stereotypically male or androgynous, with a notable absence of female typologies. Our findings suggest that this relationship has an influence on the continued predominance of male entrepreneurial activity. This study contributes to the growing empirical literature on female entrepreneurship from an understudied perspective; gender stereotyping, demonstrating that socially constructed gender stereotyping persists in contemporary Spanish culture.     

Conditionally heteroscedastic unobserved component models and their reduced form

The reduced form of the local level model with conditionally heteroscedastic GARCH(1,1) noises is analyzed. We show that the IMA-GARCH model is a good alternative but its conditional heteroscedasticity is weaker than this of the unobserved disturbances.
