Technical,quality and environmental efficiency of the olive oil industry

This paper studies the level of technical efficiency in the olive oil industry from a multi-output perspective, and examines olive oil production in quantitative and qualitative terms. The study also covers the environmental impact of the production process. These are key issues due to the current environmental, organoleptic and food traceability requirements of the EU Common Agricultural Policy (CAP). Furthermore, product differentiation is sought after in today’s ever more demanding markets. The production of olive oil in Andalusia (Spain) is the most important agricultural food industry in the whole region and it represents 30% of world olive oil production. Three data sources have been used: a comprehensive survey to a sample of olive oil producers, their financial reports, and the opinion of a group of experts in olive oil production techniques interviewed by means of the Delphi survey. With this data and after the construction of indicators, a production frontier is elaborated by applying an extension of the Data Envelopment Analysis (DEA) technique. This will allow for the measuring of the relative technical efficiency indices and set specific efficiency indices for both the quality of the oil produced and the environmental impact of the production process. Those factors impacting on efficiency are determined by a truncated regression model with bootstrap. The results show a medium–high level of relative technical efficiency and highlight the importance of efficiency factors involving production and marketing associations.     

农村转移劳动力就业质量实证研究--基于河北省的实证分析

如何进一步提高农村转移劳动力就业质量,事关国民经济健康顺利发展,同时也是确保我国城镇化建设顺利实施的关键。通过对河北省农村转移劳动力抽样调查的结果分析,发现经济发展水平、城乡二元体制、就业市场分割、就业歧视以及劳动者素质是影响农村转移劳动力就业质量提高的原因。要想确保农村转移劳动力就业质量不断提高,就必须让政府和企业共同发挥作用,转变就业理念,完善社保体系,发挥工会作用,健全工资增长机制等,从多角度入手来提高劳动者就业质量。     

Exchange rate pass-through and product heterogeneity: Does quality matter on the import side?

This paper investigates theoretically and empirically the heterogeneous response of exporters to real exchange rate fluctuations due to the quality of imported inputs and exported output. We develop a model where the production of high-quality products requires high-quality inputs sold in monopolistically competitive foreign markets. The model predicts that exporters using imported inputs have low exchange rate pass-through, but this effect is weaker for firms shipping high-quality goods. This is due to the heterogeneous price adjustments of foreign suppliers selling inputs of different quality. We test the predictions of the model using Italian firm-level trade data for the period 2000–2006. The empirical analysis shows that the imports of intermediates have a significantly weaker effect in reducing the exchange rate pass-through into the export price of high-quality varieties. By showing that the import price of high-quality inputs is less sensitive to exchange rate variations, we provide evidence supporting the theoretical hypothesis that the pricing power of input suppliers weakens the import channel.     

基于人力资本理论的高校教师激励机制研究

高校教师是高校最重要的资源,伴随着高校人事制度的改革,高校人力资源管理工作正朝着制度化方向发展。人事制度的改革给高校注入了活力,促进了高校人才资源的开发,但仍面临着各种冲击和争议。从人力资本的视角研究高校教师的价值,分析高校教师作为一个特殊的群体,其人力资本的形成、特性以及在高校环境下的作用,以实现高校教师人力资本的积累,实现激励方式的多样化为目的,从新的角度探讨高校教师激励问题。

Racing in two dimensions

In this paper we study an industry in which there is an ongoing sequence of R&D races between two firms. Firms are engaged in product innovation. Products are horizontally and vertically differentiated. There are two key characteristics/dimensions to products, and the level at which these are embodied in products can be increased by R&D. At each time firms can spend R&D on improving their product in one or both dimensions. We allow the possibility of economies scope — so R&D undertaken in one dimension can spillover to the other. The question we are interested in is whether a firm that is ahead in a single dimension but behind in another will focus all its R&D effort in the area in which it is ahead (product specialisation), or whether it will try to do R&D in both dimensions in the hope that it might get ahead in both and end up with a superproduct that dominates in both characteristics. The outcome of this R&D competition determines a Markov transition probability matrix determining the evolution of the industry. We show that when the R&D technology is characterized by constant returns then the only steady-state outcome is one in which the economy stays forever in a position in which one firm produces a super-product and the other gives up doing R&D altogether. This outcome is unaffected by the degree of economies of scope. When the R&D technology is characterised by decreasing returns, then the industry will visit all states and so will exhibit both product specialisation and superproduct dominance at various times. Now the extent of economies of scope matters and we show that the greater the extent of economies of scope, the less likely is the industry to exhibit product dominance, and the more likely it is to exhibit product specialisation.
