El efecto Harrod-Balassa-Samuelson El caso de México

This paper discusses the Harrod-Balassa-Samuelson (HBS) effect in Mexico during the period 1970-2009. In so doing, we use an econometric model that incorporates structural changes. The results achieved in this research suggest that the HBS effect does not hold in the case of Mexico and the United States during this period, and thus it was not statistically corroborated that the different rates of productivity growth in the tradable and non tradable goods between these countries affected the real exchange rate.     

Human resource management and developing proactive environmental strategies: The influence of environmental training and organizational learning

The need to implement advanced approaches to protect the environment is forcing companies to refocus their internal procedures and actions. To match employees' capabilities and the organization itself to these new requirements, the human resource management department can offer some key tools. This article analyzes whether environmental training (ET) and organizational learning (OL) positively influence the development of proactive environmental strategies (PESs) and compares the two processes, which differ in the time, costs, and difficulty required to implement them. Companies in the tourism sector are currently facing a highly dynamic environment where innovativeness is a decisive factor for achieving competitiveness. As such, we analyze whether the presence or absence of innovativeness influences the development of these two mechanisms. Using a sample of 252 tourism companies, we tested these relationships using structural equation modeling. The findings showed that (1) innovativeness is an antecedent of implementing ET and OL in the companies sampled, (2) both mechanisms promote implementing PESs, and (3) ET is equally as effective as OL for this purpose. Managers should take these findings into account when deciding which mechanism to apply when striving to achieve environmental proactivity.     

Entrepreneurship and competitiveness dynamics in Latin America

This study analyses the relationship between entrepreneurial dynamics and the level of competitiveness in Latin American countries. Based on a stage of economic development model, we demonstrate that Latin American countries under the model followed different paths related to competitiveness. These different paths can explain the effect of specific competitiveness conditions on entrepreneurial dynamics in Latin America.

A new family of dispersive orderings

In this paper we introduce a new family of univariate dispersion orderings which, under mild conditions, includes the weakly dispersive ordering as a particular case. Different properties of the new class of dispersion orderings are analyzed. Some connections with other univariate dispersion orderings are stated. Finally an application of the new family of dispersion orders to the field of genetics is developed.     

An upper bound for the correlation ratio of records

We obtain an upper bound for a measure of the performance of the least squares predictor of the jth record of a sequence of continuous i.i.d random variables as a function of the ith record. We show also that such bound is attainable, except for location and scale parameters, by exponential distributions.

Smart destinations and the evolution of ICTs: a new scenario for destination management?

The impact of information and communication technologies (ICTs) on tourism and their foreseeable future evolution seem to be shaping a new scenario for destination management. This new context has given rise to the need for new management models. One of these models is the emerging smart tourism destination (STD), although it requires greater conceptual precision in order to become a new paradigm for destination management. This paper proposes a systemic model for STDs which facilitates the interpretation of the role of ICTs in the management of tourism destinations. Accordingly, the Delphi technique has been applied so as to determine the opinion of experts regarding the feasibility of the STD approach, its advantages and limitations and also the size of the impact of ICTs on the management and marketing of tourism destinations. This prospective exercise highlights the intensification of the impact of ICTs over the coming years which will shape a new scenario for management characterised by technology and data management. However, the efficiency of the STD approach will not depend exclusively only on technology but also on an appropriate governance of the destination that systematically incorporates the three levels of the STD, namely the strategic–relational, instrumental and applied levels.
