贫困与中国经济长期稳定增长的聚类分析

依据聚类分析,从收入差距、失业率与人口增长三个方面分析贫困对中国经济长期稳定增长的影响.结果可以看出,失业率与经济增长从负相关关系到正相关关系转变;经济的高速增长伴随着收入差距的扩大,但收入差距的扩大应当取决于经济增长的性质与经济结构;人口增长率与经济增长率之间存在一定的正相关关系.因此,解决贫困问题不仅要依赖经济的长期稳定增长,同时要考虑经济增长的结构特征.     

完全美元化及利弊评析

完全美元化是指完全放弃本币，使用外币(美元)作为记账单位、支付手段或价值储藏，具有无限法偿能力，其实质是完全而不可逆转的固定汇率制度。评析了完全美元化的利与弊，指出完全美元化是一把“双刃剑”，其无论对于美元化国家还是对于美国都会带来一定的经济利益，但同时也会造成一定的损失。     

奥肯定律与扩大的奥肯模型估计——关于中国就业与经济增长的数量关系实证(1978-2003)

奥肯定律表明与正常的(或潜在的或趋势的)增长率相比,高产出增长伴随着失业率的降低,低产出增长伴随着失业率的上升.作为一种经验规律,奥肯定律在西方很多国家的实践中得到了良好的验证.本文根据1978年以来中国的宏观经济统计数据进行模型回归检验,结果显示我国城镇登记失业率的变化与实际产出增长率之间不存在典型的奥肯规律.由于我国公开的失业率并不能反映真实的市场失业率,为此用就业量代替失业率,建立扩大的奥肯模型,分别对我国第一、二和三产业的就业增长与经济增长的数量关系进行估计.实证的结果显示我国第二、三产业的就业增长与产出增长和物价上涨均为正相关;而我国农业的就业增长与产出增长存在负相关.

A Schumpeterian model of equilibrium unemployment and labor turnover

This paper constructs a general equilibrium model of equilibrium unemployment by combining an endogenous growth model with a variant of equilibrium search theory. The analysis offers two explanations for the causes of widening wage gap between skilled and less-skilled labor, and rising unemployment rate among the less skilled: technological change in the form of an increase in the size of innovations or skilled labor saving technological change in R&D activity. In addition, the model identifies two distinct effects of faster technological progress on the aggregate unemployment rate. First, it increases the rate of labor turnover and therefore increases the aggregate unemployment rate – the creative destruction effect. Second, it creates R&D jobs, which offer workers complete job security, and consequently reduces the aggregate unemployment rate – the resource reallocation effect.     

Economic Benefits Resulting From Irrigation Water Use: Theory and an Application to Groundwater Use

Traditional economic analysis using a crop production function approachhas assumed that all variable factors, including irrigation water, arefully employed in the crop production process. However, this paper firstdemonstrates that economic benefits of irrigation water areoverestimated when the crop production function, and therefore theirrigation water demand function, is expressed in terms of irrigationwater supplied, rather than consumptive irrigation water use. Second,the paper demonstrates that the magnitude of the estimation bias isproportional to the rate of irrigation water losses through leaching,runoff and evaporation. Consequently, the model misspecification problemwould lead to increased irrigation water use and reduce incentives forfarmers to adopt improved irrigation technologies.     

Private benefits from control block trades in the Spanish stock exchange

A control block trade can be explained by the expectation of financial gains, shared by all shareholders, or by the expectation of private benefits, exclusive to the buyer and possibly at the expense of other shareholders’ rents. The market for corporate control contributes to social welfare when it improves the efficiency of the allocation of resources. When the objective of a block transaction is private benefits, social welfare may be negatively impacted as minority shareholders could withdraw from the market. Therefore the estimation of private benefits would allow the efficiency of the market for corporate control to be assessed. Specifically, the aim of this paper is to calculate private benefits in the Spanish market for partial control. Using a sample of partial control transactions over the period 1990–2016, we find that the median of private benefits is negative, therefore it appears that there is no inefficient use of resources in the Spanish partial control market as a whole, however private costs are detected. The variability of private benefits is explained in a significant way by variables related to the control structure of the target firm, such as the controlling position of the buyer after the transaction, the contestability of control and the cross-shareholdings between the buyer and large shareholders. Performance and the size of the firm are significant as well.
