A comparative multidimensional evaluation of conservation agriculture systems: A case study from a Mediterranean area of Southern Italy

To avoid the current paradoxes of the global agro-food system it is necessary to define and implement a viable agricultural sustainable model, combining satisfaction of food needs and land preservation. A possible solution can be found in a holistic production system consistent with a sustainable development model, designed to satisfy diverse “local” economies. The conservation agriculture (CA) could be a part of this model, as it includes a set of best practices available to preserve agrarian soil and its biodiversity. Briefly, we cover the CA background in Europe followed by the evaluation of its impact in terms of private/public interest, using the sustainability’s metric.To test the viability of a model based on CA in “local conditions”, we compare economic performance of different conservation practices (i.e. minimum and no tillage) to that of conventional agriculture in a typical Mediterranean environment – Collina Materana – in Southern Italy (Basilicata region). Our findings suggest that: i) CA can actually be a viable alternative to conventional systems; ii) in Mediterranean agricultural areas CA has yield advantages especially during dry years, when conservation techniques increase water supply to crops; iii) public support is needed to direct farming choices in fact without financial incentives these practices would be not widely accepted and diffused; iv) European policy makers have to recognized the positive benefits of CA and pay them as ecosystem services in the framework of Good Agricultural Environmental Conditions and the present CAP subsidies.     

Openness to trade as a determinant of the macroeconomic elasticity of substitution

Several theoretical and empirical studies on economic growth consider the macroeconomic elasticity of substitution between capital and labor as a measure of economic flexibility that depends on technological as well as institutional aspects. One institutional aspect of economic flexibility is openness to trade. I examine in a Heckscher–Ohlin model with two large countries trading intermediate goods how openness affects the elasticity of substitution. If the technology has a constant elasticity of substitution in a closed economy, opening up to trade raises the elasticity of substitution only in the country that accumulates capital at a faster rate.

中国的经济发展战略与地区收入差距

本文认为 ,当前中国大陆各省区市之间发展水平差距的主要原因在于 ,重工业优先发展的赶超战略下形成的生产要素存量配置结构 ,与许多省区市的要素禀赋结构决定的比较优势相违背 ,从而导致大量的赶超企业缺乏自生能力。基于各省区市的数据进行的实证研究与我们的假说相容。

Input–Output Structural Decomposition Analysis: A Critical Appraisal

Over the past decade, input–output structural decomposition analysis (SDA) has developed into a major analytical tool. We review the development of SDA and its relationship to other methodologies. We present the fundamental principles of alternative approaches to deriving SDA estimating equations and explore the various decompositions of changes in IO tables. We also identify several complications and unresolved issues. Most importantly, we find that a rigorous grounding in economic theory is lacking for SDA, but we are able to offer some suggestions as to how it might be established.     

Trends and Forecasts for Inbound Tourism to China

Summary

The development of tourism in China over the last two decades is reviewed. It is argued that the success of the economic reforms in China which has resulted in fast economic growth has also been the main cause of rapid tourism growth in China. Forecasts of international tourist arrivals by source country market and destination region within China are generated over the period 2001-05. An integrative approach is used which combines both time-series and econometric methodologies, termed structural integrated time-series econometric analysis (SITEA).     

The role of social capital in encouraging residents' pro-environmental behaviors in community-based ecotourism

This study integrated the theoretical perspective of social capital into community-based ecotourism (CBET). Two destinations were selected to test the conceptual model to see whether social capital improves cooperation between community residents and the coordination of CBET development, and whether its role is persuasive and encourages residents' pro-environmental behaviors. The sample consisted of 420 residents living in two typical ecotourism destinations in China. Findings from a two-stage structural equation model analysis show that economic benefits have a direct impact on residents' pro-environmental behaviors; and the cognitive, rather than structural social capital has a partially mediating effects on this relationship. These findings indicate that a high level of social capital, particularly the cognitive variant, is instrumental in encouraging residents' pro-environmental behaviors.
