Gay tourism in a sun and beach destination

Gay tourism is seen as an attractive business opportunity for many destinations. However, there is a lack of research at identifying the resources necessary for success in this type of tourism. This work is aimed at filling this gap by using the premises of the resource based view and transfers them to the analysis of territories to identify the valuable resources that are required for a sun and beach destination to attract gay tourists. To this end, this study has focused on a gay tourism sub niche, tourists lodged in gay-exclusive resorts in Gran Canaria. In order to confirm the validity of this approach, the relationship between the satisfaction of gay tourists and the condition of the valuable resources was studied by means of a robust statistical new method, namely Bayesian model averaging. That method permits the inclusion of uncertainty in the theoretical models that determine destination competitiveness, thus reducing many of the problems that arise in the application of the more conventional statistical methods in this type of analysis.     

INTERTEMPORAL COMPETITIVE EQUILIBRIUM,CAPITAL AND THE STABILITY OF TÂTONNEMENT PRICING REVISITED

This paper reconsiders a recent criticism which contends that the theory of general intertemporal equilibrium, formulated by taking the physical endowments of capital goods as given, is not protected from the problem of capital at the centre of the two Cambridges debate of the 1960s. The author confirms such a criticism following a different approach. He argues that the stability analysis of an intertemporal equilibrium via tâtonnement must be consistent with a uniform rate of return on capital. He shows that the resulting non‐orthodox tâtonnement subverts the traditional analysis of equilibrium stability.     

Users' perceptions of the free,virtual-only service experience

Like manufacturing multinational enterprises, multinational banks, although being more subject to local regulation and market preferences, are increasingly changing their international attitude. Namely, they rely on foreign activities not only as a means to exploit their own competitive advantages within foreign markets, but also to access exclusive assets, resources, and competencies that could be transferred back to the whole network to enhance and strengthen their competitive advantages. The reported research refers to data on the evolution of the Italian banks' foreign initiatives in the 1998–2004 period. Using such data, the authors investigate the determinants of the coexistence of strategies that are both competence-exploiting and competence-enhancing, using the traditional eclectic approach.     

A learning methodology using Matlab/Simulink for undergraduate electrical engineering courses attending to learner satisfaction outcomes

Learner-centred approaches follow the prevailing tendency in modern University reforms which are primarily concerned about “how people learn”. The methodologies can be learner-centred in the sense of placing the student as the main actor of the teaching–learning process by increasing his interactivity and participation, but also considering what is relevant for the student by measuring the learner satisfaction. In order to promote both aspects, this paper proposes a synchronous software-based active methodology that makes use of the simulations to show a virtual scenario to the students and challenge them to predict and discuss the evolution of the scenario. The proposed methodology improves the visual interface, promotes discussion both among students and with the teacher in a brainstorming stage and shows real-world examples. This software-based methodology has been implemented into an Electric Machinery course at the University of Seville (Spain), and the evaluation has been carried out considering both the affective and cognitive domains. Principal components analysis proves to be useful to highlight the dimensions with a higher influence on learner satisfaction and the affective and cognitive results confirm the successful implementation of the proposal.     

Pricing options under stochastic volatility: a power series approach

In this paper we present a new approach for solving the pricing equations (PDEs) of European call options for very general stochastic volatility models, including the Stein and Stein, the Hull and White, and the Heston models as particular cases. The main idea is to express the price in terms of a power series of the correlation parameter between the processes driving the dynamics of the price and of the volatility. The expansion is done around correlation zero and each term is identified via a probabilistic expression. It is shown that the power series converges with positive radius under some regularity conditions. Besides, we propose (as in Alós in Finance Stoch. 10:353–365, 2006) a further approximation to make the terms of the series easily computable and we estimate the error we commit. Finally we apply our methodology to some well-known financial models.      

Buyer–Supplier and Supplier–Supplier Alliances: Do They Reinforce or Undermine One Another?

abstract    Previous research has portrayed buyer–supplier and supplier–supplier alliances as important mechanisms to foster learning and exchange efficiencies. Controversy remains, however, as to how these alliances interact. While some propose they reinforce one another (e.g. learning in horizontal ties generates positive spillovers to vertical ties), others propose a negative interplay (e.g. when increasing vertical-tie intensity, suppliers may weaken horizontal ties to avoid retaliation from buyers who wish to preserve bargaining power). We empirically test these competing views using survey data from the Brazilian auto-parts industry. In an attempt at reconciliation, we propose that the positive or negative interaction between vertical and horizontal alliances depends on the level of technological uncertainty of goods exchanged. Vertical ties seem to inhibit horizontal ties when technological uncertainty is low; when technological uncertainty is higher, vertical and horizontal ties do not seem to have any meaningful form of interaction. We discuss implications for theory and practice.     

Sovereign Debt Capacity and the Distribution of Domestic Wealth: A Common Agency Model*

This paper proposes a stylized two‐period, two‐country model illustrating the role of distribution of domestic wealth in determining a country's level of access to international lending. We model sovereign debt redemption policy in a common agency framework. Within this framework, policy is the outcome of the interaction between government and local and foreign interest groups with conflicting preferences on debt repayment. Our main result is that in full lobby competition, when all interests are represented, the only equilibrium solution is repudiation and the consequent inability of government to access international capital markets. Conversely, when the ability to lobby depends on wealth, governments can access international credit up to a given maximum external debt capacity, determined by the skew in the distribution of domestic wealth.     

The inequality trap. A comparative analysis of social spending between 1880 and 1930

It is often assumed that the fight against inequality played an important role in the rise of the welfare state. However, using social transfers as an indicator of redistribution and three alternative proxies for inequality—the top income shares, the ratio of the GDP per capita to the unskilled wage, and the share of non‐family farms—this article shows that inequality did not favour the development of social policy between 1880 and 1930. On the contrary, social policy developed more easily in countries that were previously more egalitarian, suggesting that unequal societies were in a sort of inequality trap, where inequality itself was an obstacle to redistribution.     

Managers, investors, and crises: mutual fund strategies in emerging markets

We examine the trading strategies of mutual funds in emerging markets. We develop a method for disentangling the behavior of fund managers from that of underlying investors. For both managers and investors, we strongly reject the null hypothesis of no momentum trading: mutual funds systematically sell losers and buy winners. Selling current losers and buying current winners is stronger during crises, and equally strong for managers and investors. Selling past losers and buying past winners is stronger for managers. Managers and investors also practice contagion trading—they sell (buy) assets from one country when asset prices fall (rise) in another.
