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.     

素质教育应把德育放在首位

在素质教育中,在人才素质的诸要素中,思想道德素质是根本、是灵魂。这是最具有时代特征的新型人才观,也是素质教育的核心。思想道德素质制约和影响着学生的人生观和价值观;思想道德素质决定和影响着学生的治学态度;思想道德素质决定和影响学生毕业的发展和职业道德。

碳排放、绿色全要素生产率和经济增长

通过把资本存量、就业人数、能耗、时间等变量纳入超越对数生产函数,将碳排放总量、能源强度等变量以及区域虚拟变量作为生产无效率函数的解释变量构建随机前沿模型进行实证分析。结果显示：碳排放增长会扩大技术无效率项并降低绿色全要素生产率;技术进步降低了能源强度却引至了更多的碳排放,符合杰文斯悖论;减排技术较高的地区对应较高绿色全要素生产率增长水平;绿色全要素生产率增速比传统全要素生产率增速更快。     

海西发展战略与固定资产投资需求分析

政府有关部门根据海峡西岸经济区发展战略制定了该区域近中远期的经济发展目标,以这些发展目标作为预测海西区域资金总需要的重要约束条件。利用变量的样本时间序列得出福建省全社会固定资产投资的预测模型,以2009年作为预测基期,得出纵向预测结果。同时,将其与先发地区进行横向比较,获得经验性的数据以对纵向预测结果进行修正,据此得出福建近中远期的全社会固定资产投资的预测值。     

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.
