According to conventional portfolio theory, an increase in the interconnectedness of international financial markets may reduce the potential for constructing diversified portfolios. This article explores the implications of the creation of the Latin American Integrated Market (MILA)1 over the dependence structure of its members using correlation and cointegration analysis as well as linear and nonlinear Granger causality tests. The creation of MILA aimed to enhance the integration process that Latin American financial markets “naturally” present while still providing diversification opportunities to investors. The results of our empirical analysis suggest that such objective is being achieved. Evidence of a rise in cross-country linear correlations and their linear causal relationship supports the idea of an increasing financial integration process in the region, while the absence of cointegration and the weakening of the nonlinear causal relationship favors the creation of diversified regional portfolios. These findings provide valuable insights for investment portfolio designers, regulators, and supervisors. 相似文献

Since 2002, the Institute for Peace Promotion and Injury/Violence Prevention (CISALVA) at the Universidad del Valle, Cali, Colombia and the Colombia Program at Georgetown University have developed and implemented 21 epidemiologically based municipal crime observatories in intermediate-sized municipalities in Colombia. These crime observatories serve as monitoring centres that provide low cost, geo-referenced methods of data collection and analysis, which allow cities to develop more responsive policies and prevention programmes and enhance governance. This article focuses on the methodology employed and lessons learned that may be applicable to similar settings. Worth noting within the results was a significant decrease in homicides after the first year of the programme. Whether or not such results could be attributed to the method or to the nature of the interventions and policy initiatives stemming from it remains open to conjecture. 相似文献

This paper aims to identify some factors that may be explaining differences among secondary students in start-up intentions.
For that, the study develops an entrepreneurial intention model sustained by the use of Azjen’s Theory of Planned Behaviour
(TBP). Using a sample of students aged between 14 and 15 years old, a questionnaire based on the Li?án and Chen’s Entrepreneurial
Intention Questionnaire was administrated. The purpose is to test a model of entrepreneurial intention using structural equations.
The findings point that TPB is an appropriate tool to model the development of entrepreneurial intention through pedagogical
processes and learning contexts. The education and training should centre itself much more in changing personal attitudes
than in knowledge. Moreover, it is desirable that an entrepreneurship educational programme could contribute to the development
of competences related to entrepreneurship, social and civic skills, and cultural awareness. 相似文献

While the biofouler Corbicula fluminea (Müller, 1774) is known to cause great economic losses in North America, studies reporting the problem in Europe are much scarcer. This paper explores the industrial effects of the species in Portugal, the gateway by which the bivalve entered Europe around 30 years ago. National waterworks, major power stations, cement plants, pulp and paper mills and irrigation systems were surveyed. The industrial impacts of the pest were shown to remain relatively mild; irrigation systems are those that seem to be facing more significant economic losses due to infestation. Possible reasons for the apparent discrepancy between this result and the species dispersal in natural ecosystems are discussed, and recommendations on adequate responses to the latent threat are provided. This study may assist the implementation of integrated pest management policies in countries at risk of invasion or recently invaded, and contribute to an understanding of the species’ progression in industrial environments. 相似文献

There exist few quantitative assessments of the relationship between biodiversity per se and economic benefits at scales that are relevant for conservation. Similarly, the merits of Community-Based Natural Resource
Management programs for both wildlife and people are contested. Here, we harness two databases, on wildlife surveys and financial
benefits, to address these issues for communal conservancies in northwest Namibia. We use ordination methods to characterize
the diversity and stability of large wildlife assemblages on conservancies, and demonstrate that diversity (but not stability)
is an important explanator of conservancy financial benefits. Our results indicate that for this area of Namibia, biodiversity,
as represented by large wildlife assemblages, has an important, positive effect on the tangible financial benefits that people
derive from conservation programs. 相似文献

The moral ideology of banking and insurance employees in Spain was examined along with supervisor role modeling and ethics-related
policies and procedures for their association with ethical behavioral intent. In addition to main effects, we found evidence
supporting that the person–situation interactionist perspective in supervisor role modeling had a stronger positive relationship
with ethical intention among employees with relativist moral ideology. Also as hypothesized, formal ethical polices and procedures
were positively related to ethical intention among those with universal beliefs, but the relationship was much weaker among
relativists. Thus, firms wishing to optimally promote ethical attitudes and behavior must tailor their organization-based
initiatives to the individual characteristics of their employees. 相似文献

This paper proposes a nonparametric procedure to estimate market power for first‐price auction data and applies the procedure to cattle procurement markets. Most previous studies have used parametric methods, which require specific functional forms for retail demand, input supply and processors’ cost equations. However, researchers often find that market power estimates from parametric methods are sensitive to the choice of functional forms and specifications. An application to data from cattle procurement experiments shows that our nonparametric approach greatly outperforms commonly used parametric methods in estimating the degree of market power. While parametric estimates are sensitive to functional form specification and are at least 90% smaller than ‘true’ market power indices, estimates from our nonparametric procedure deviate from the actual value by no more than 25%. 相似文献

Using a large sample of micro data from four waves of Community Innovation Survey for EU member states, we investigate the relationship between firms’ export status and different sorts of innovation activities. We find systematically positive relationship between the two, whereby the strongest correlation is found in case of product innovation and the weakest in case of organizational innovations. While aggregate data show that innovation success is increasing in firm size, we find that exporting has the strongest effect on innovation in the medium-sized firms. We also explore cross-country differences in the impact of export status on innovation. Countries with a higher share of exports in GDP and greater share of spending on research and development generally display a stronger correlation between exporting status and innovation. 相似文献

This article presents an econometric approach to modeling uncertainty, unwillingness to pay, and protest behavior in contingent valuation studies. For that purpose, a mixture model with sample selection is developed for a multiple‐bounded uncertainty elicitation format. The proposed theoretical framework is applied to evaluate the social welfare impact of implementing a sustainable rural development program. Results show that a “naive” analytical approach that excludes protesters from the analysis would result in significantly higher willingness to pay estimates for those individuals who favor the implementation of the program and agree to reveal their true reservation prices. 相似文献
