The impacts of the tourism sector on the eco-efficiency of the Latin American and Caribbean countries

The impacts of the tourism sector on the overall eco-efficiency of 22 Latin America and Caribbean countries from 1995 to 2016 were examined. A Data Envelopment Analysis was used to calculate the overall eco-efficiency of each country (considering the CO₂ emissions as the input and the GDP as the output). Posteriorly, a Panel Autoregressive Distributed Lag model was applied to analyse the impacts of tourism arrivals, tourism capital investment, and direct tourism contribution to employment on eco-efficiency. The results indicated that tourism arrivals decrease these countries eco-efficiency, both in the short- and long-run. Contrariwise, tourism capital investment and direct tourism contribution to employment seem to promote eco-efficiency in the long-run. These findings recommend that policymakers should respect these destinations carrying capacity and, simultaneously, encourage investments in sustainable tourism projects and productive employment to all.     

Reterritorialization practices and strategies of campesinos in the urban frontier of Bogotá, Colombia

Much of the research on urbanization has focused on how rural populations move to cities for work opportunities. This paper takes a different perspective on the relations between rural populations and urbanization. The livelihoods of rural dwellers on the outskirts of the city of Bogotá in Colombia are increasingly affected by the expansion of urban activities and infrastructure. Therefore, urbanization takes place in the areas of residence of the rural populations; these people do not migrate to the city but, rather, the city migrates to them. Consequently, rural ways of life face growing competition from the production of commodities and services on the urban-rural fringe, including quarrying and landfills serving the needs of industries and urban populations. We explore how rural populations and their livelihoods have transformed as a response to these urban dynamics and the expansion of the city. We focus on the strategies that the rural populations employ to deal with the physical and socio-ecological impacts of this change. The defense of peri-urban livelihoods through these strategies is simultaneously social and spatial and has been partially successful. However, increasing social and environmental inequality, including worsening access to land, water and vital ecological functions, tends to lead to a general reduction in the quality of life in the urban frontier.     

Home country uncertainty and the internationalization-performance relationship: Building an uncertainty management capability

We analyze the impact of home country uncertainty on the internationalization-performance relationship of emerging market firms. Building on organizational learning theory and the institutional approach, we argue that internationalization has a positive impact on the performance of emerging market firms, and that this relationship is strengthened for firms based in emerging countries with higher corruption and political risk. The reason is that by being exposed to high levels of home country uncertainty in the form of political risk and corruption, firms develop an uncertainty management capability at home that helps them face the challenges of internationalization better. We also propose that this uncertainty management capability helps emerging market firms perform better outside of their home region. We test our arguments on a sample of 536 firms from Argentina, Brazil, Chile, and Peru.     

The political impact of tourism dependence in Latin America

This research seeks to test empirically the validity of hypotheses drawn from dependency theory that suggest that economic reliance on tourism creates political dependence. Specifically, it seeks to determine whether the Carribean region, strongly dependent on U.S. tourism, is demonstrably more compliant politically with the United States than other, less dependent, Latin American nations. In addition, the paper examines the relation between political compliance and other indicators of dependence, e.g., investment, aid, and trade. Compliance is measured basically by correlating each nation's voting behavior in the UN General Assembly with that of the United States. A series of tests on a number of relevant economic and political variables yields no confirmation of the dependency argument in the political realm.

Profitability in Banks Affiliated to a Business Group: Evidence from Mexico

In certain institutional contexts, where there are business groups, banks affiliated to these business networks are faced by incentives that might condition their profitability. The objective of this article is to test whether there is a difference between the performance of affiliated banks and that of banks not affiliated to groups, in the context of an emerging market. In particular, a study is made of the case of Mexico in the period 2007–11. Findings suggest that banks affiliated to business groups show less profitability than non-affiliated banks, which may be a consequence of the provision of loans in an internal capital market.     

Port system evolution – the case of Latin America and the Caribbean

The explosion of global container trade in the last two decades has significantly influenced the port geography of Latin America & the Caribbean (LAC), leading to a concentration of container traffic at selected ports. Theory suggests that, as port systems become mature, they tend to deconcentration, partly due to the emergence of secondary ports. Previous research has examined the region’s dominant ports, but an unanswered research question is how the evolution of this port system is influencing and being influenced by the actions of those ports currently occupying a secondary rank in the LAC port hierarchy.The methodology is based primarily on analysis of time series data on container movements between 1997 and 2012, revealing patterns of cargo flows and transhipment location choices. The institutional context of devolution processes and new investments in the region provides additional insight into the performance of selected ports. From a theoretical perspective, this analysis is situated within the context of recent institutional approaches that examine the port’s ability to act through critical moments and junctures, in order to deepen understanding of which of the various factors influencing port system deconcentration are the most sensitive to successful institutional adaptations.Results show that the manufacturing of strategic locations can be successful and may have driven the emergence of secondary ports in the LAC system. This finding demonstrates how path dependence can be challenged by new developments, the identification and success of which are nevertheless contingent on factors such as the first mover advantage, port planning regimes and diversification of port roles. The paper identifies some of the key factors influencing the transition of a port system from concentration at a few dominant ports to a deconcentrated system of primary and secondary ports, which can be applied to other port systems in future research.     

我国对美国白羽肉鸡产品反补贴案上游补贴规则的运用与述评

通过对美国肉鸡产品反补贴案法律规则适用情况的分析,发现这是我国商务部借鉴美国上游补贴规则的理论和实践,首次运用上游补贴规则进行补贴利益传递分析并做出肯定性裁决的案件。尽管在我国法律法规没有明文规定上游补贴规则的情况下,我国商务部的这种做法可能存在重大的法律瑕疵,但也表明了我国亟需制定上游补贴规则的紧迫现实。为此,现阶段我国的上游补贴立法和实践应注意投入产品所接受补贴的性质、上游补贴的保护对象、上游补贴的地域性限制及审慎适用等问题。
