我国化肥价格波动与农民收入关系的实证分析

本文利用1978～2008年的时间序列数据,运用脉冲响应函数和方差分解技术考察化肥价格波动与农民收入之间的关系,发现化肥价格的波动与农民收入变化之间存在着双向的因果关系,即化肥价格的上涨导致农民增收缓慢,而化肥价格上涨的根本原因在于＂需求拉动＂和＂成本推动＂。今后必须从需求和供给两方面采取对策：一方面通过建立化肥直接补贴制度和化肥储备制度,从需求上控制化肥价格上涨;另一方面通过采用新型化肥生产技术和给予化肥生产企业生产用能以优惠政策,从供给上控制化肥价格上涨。

“省直管县”财政体制如何促进经济增长——基于江苏省2004-2009年数据的实证分析

近几年来,"省直管县"财政体制在各省陆续实施,其主要目的在于克服既有的市管县体制存在的各种弊端。可以预期,这项改革措施有减少行政管理成本、解决县乡财政困难、促进县域经济增长等多种潜在作用。但可能存在的问题是,该财政体制如何促进经济增长?文章利用江苏省51个县(市)2004-2009年的空间面板数据进行分析发现,"省直管县"财政体制对经济增长的作用主要是通过县(市)扩权而产生的"政府竞争效应"实现的。     

银行业为何是大赢家?——一个基于竞赛理论的分析

文章以竞赛理论为视角,分析当前我国银行业整体业绩表现突出的原因。得出如下结论:银行业垄断、存贷高利差、信息优势以及货币产品经营者等"先天优势"促成了我国银行业大赢家的局面。这一局面会激励各行业之间展开银行牌照竞赛,产生租金耗散,影响实体经济。文章对此进行分析,并得出结论与政策建议。

Revisiting the labor supply effect of social security earnings test: New evidence from its elimination and reinstatement in Japan

We explore the labor supply effect of the social security earnings test in Japan on those aged 65–69 years through a combined examination of the elimination of the earnings test in 1985 and its reinstatement in 2002. We present evidence showing that the effects of changes in the earnings tests on the labor supply of the elderly are not symmetric, controlling for changes in the attributes of workers and firms. The repeal of the earnings test in 1985 did affect the earnings distribution of the elderly (especially for male), while its reinstatement in 2002 did not alter the earnings distribution.     

The impact of agricultural policy on farm income concentration: the case of regional implementation of the CAP direct payments in Italy

One of the objectives of agricultural policy worldwide concerns the support of farm income. Common Agricultural Policy direct payments (DPs) are the main instruments to support farm income in the European Union. This article addresses their role in the concentration of farm income. This is done by calculating the Gini coefficient and its disaggregation in a large sample of Italian farms in the period between 2006 and 2007. Although this approach has been used to develop ex‐post analysis in previous studies, this article is innovative given that it is used here in an ex ante analysis aimed at evaluating the likely impact of a recent reform proposal. This latter requests changing the current model to a regional model of DPs application to make payment rates (i.e., payment per hectare) homogeneous among farms in the same region. The analysis shows that DPs and farm incomes are both very concentrated but that DPs allow for an income concentration reduction in Italian farms. The shift to a regional implementation reduces DPs concentration and, to a limited extent, farm income concentration. Of the considered regionalization scenarios, those that redistribute DPs among regions are the most effective in reducing concentration. The extension of the Gini considered approach to an ex ante setting seems effective because it provides insights that could feed the policy debate regarding the forthcoming reform.

Capability accumulation,innovation, and technology diffusion: Lessons from a Base of the Pyramid cluster

Although research on industry clusters has made many valuable contributions, a dearth of empirical evidence and theoretical reflection about the characteristics of Base of the Pyramid (BOP) clusters has persisted. Consequently, the literature still lacks a framework that incorporates the context, challenges, and dynamics encountered in such clusters. Drawing from clusters, capability accumulation, and innovation literatures, we develop a theoretical framework that provides a more fine-grained understanding of the dynamics encountered in BOP clusters, the role of support organizations, the importance of capabilities accumulation in firms, and the challenges associated with technology development and diffusion within such settings. We use case study research method conducted in a traditional granite-mining cluster in Brazil, based on 154 interviews with key informants between 1999 and 2011. Our findings suggest that BOP clusters present different dynamics when compared to clusters elsewhere, because of the existence of idiosyncrasies such as additional barriers to technology diffusion, especially when coupled with a lack of coordination and misaligned policy approaches. We contribute to the literature by arguing that the process of technology diffusion in BOP clusters is hindered by these barriers, and that technology development without wide diffusion within BOP clusters can become a source of social exclusion and wealth concentration. Moreover, in large emerging economies, global pipelines are not necessarily the only path for BOP clusters to achieve competitive advantage and sustainable growth, as suggested in the clusters literature.
