综合了40多年来关于城市增长控制的研究成果,从实证分析角度的总结认为,城市增长控制会改善社区质量,提高城市区的土地价格和住房价格;从城市空间理论角度分析了城市增长控制的理论模型,理论模型可以解释实证结果,城市增长控制会提高城市土地所有者的地租,同时住房价格的提高会减少消费者的其他消费,从而会损坏消费者(尤其是租户)的利益. 相似文献

This paper examines market integration between fish species in Europe, taking international market integration into account. Based on Juselius (2006) , market integration is found both on the fresh and frozen markets. The Law of One Price is in force on the fresh market within the segments of flatfish and pelagic fish. Assuming transitivity, a loose form of market integration is identified between 13 fresh and seven frozen fish species, and the relative prices are found fairly stable. The policy implication is that catch limitation measures implemented through the Common Fisheries Policy have limited and conditional effects on prices, because of the large size of the market and varying market integration. Therefore, many fishermen are not ‘compensated’ by price increases as a result of catch limitation measures. 相似文献

Team QUINKAN competed in the GEFCom2017 final match of hierarchical probabilistic load forecasting by adopting the quantile regression method using the R package quantreg. The weather stations were clustered into 11 groups, from which an optimal one was chosen for each load meter using the boosting method. The load meter records were cleaned and/or supplemented by various methods in order to secure robust quantile predictions. The variation in the regression formulas was kept as small as possible by introducing measures for suppressing prediction instability, although special formulas were employed for loading meters that were of an industrial nature. Several procedures were applied to help improve the accuracy, such as the smoothing of season transitions, coarse graining of the relative humidity, the use of load-oriented day-type definition, the averaging of weather data, and outlier removal. 相似文献

Coffee is produced in equatorial and subequatorial regions of the world, which are also most affected by El Niño Southern Oscillation (ENSO). ENSO events have a tendency to amplify weather conditions such as droughts or excess precipitation in the affected regions, resulting in production shortage or excess supply, subsequently impacting agricultural commodity prices. In this research we assess effects of ENSO events on world coffee price dynamics using the monthly data between March 1989 and December 2010. We employ smooth transition autoregression framework to examine nonlinear dynamics of ENSO and coffee prices, and illustrate the results of this research using generalized impulse‐response functions. We find that ENSO events indeed have short‐term impacts on coffee prices. The research findings are of interest to coffee producers and intermediaries in the coffee markets as well as researchers in the fields of environmental and development economics. 相似文献

反倾销措施对产业的关联影响--反倾销税价格效应的投入产出分析 总被引:28,自引:1,他引:28
WTO反倾销协议允许成员国在倾销造成国内产业实质性损害或产生实质性损害威胁时采取反倾销措施。反倾销措施的实施在保护国内受损害产业的同时 ,会损害下游产业和消费者的利益。本文以化工行业为例 ,利用中国投入产出表定量分析反倾销税价格效应对国民经济各产业部门的关联影响。我国对外反倾销涉案产品大多是中间产品 ,因此在反倾销措施执行中应当全面考虑包括下游产业利益在内的公共利益问题。 相似文献

Determinants of residential water demand in Germany 总被引:6,自引:0,他引:6
We econometrically analyze the impact of several economic, environmental and social determinants for the per capita demand for water in about 600 water supply areas in Germany. Besides prices, income and household size, we consider the effects of population age, the share of wells, housing patterns, precipitation and temperature. We also explore why current per capita residential water consumption in the new federal states is about 30% lower than in the old federal states. Since average cost pricing may cause an endogeneity problem, we apply instrumental-variable procedures in addition to single equation ordinary least squares, but find no evidence that prices are endogenous. Our estimation results suggest that the price elasticity of water demand in Germany is around − 0.24. The income elasticity is positive, decreases with higher income levels and is at least three times higher in the new federal states than in the old federal states. Current differences in prices and income levels explain about one third of the gap in residential water use between the two regions. Household size and the share of wells have a negative impact on per capita water demand, and water use increases with age. Finally, the findings provide some evidence that rainfall patterns rather than total rainfall affect water consumption, while temperature appears to have no impact at all. All outcomes are robust to a log-log and two types of semi-log specifications for the water demand function. 相似文献

有关汇率与股价关系的最新研究,归纳起来主要有四个发展方向:一是传统宏观经济一般均衡分析方法的拓展,在以往的开放宏观经济均衡模型中将汇率与股价作为宏观经济中重要的解释变量,强化对客观经济运行的考察;二是具有微观基础的均衡分析,包括资产组合平衡与新开放宏观经济两个分析框架下的汇率与股价关系研究;三是从市场的微观结构理论对汇率与股价这两种资产价格进行模型化;四是影响汇率与股价关系的相关因素的分析。本文按照这四个方面进行文献梳理,并进行简要评述。 相似文献

通货膨胀目标制是一种以保持低而稳定的通货膨胀为首要目标的货币政策框架。本研究参照IMF提出的相关指标,并考虑到中国作为转型国家的经济特征,从中国当前经济运行中控制一般物价水平的必要性、经济结构的完善性、金融市场和银行体系的健全性、中央银行的独立性、货币政策的透明度以及央行准确预测通货膨胀的技术等方面考察了中国实行通货膨胀目标制的可行性,得出中国已经初步具备实施该货币制度的条件。并提出更彻底的制度改革将会确保中国成功实施通货膨胀目标制,从而使得宏观经济运行处于稳定的价格水平因而更有效率。 相似文献

In December 2014, the U.S. and Mexico agreed to a suspension agreement that set a $22.25/cwt import price floor on U.S. sugar imports from Mexico. A partial equilibrium trade model was developed to estimate the economic impact the agreement would have had if it had been in effect from 2008 to 2014. In years when the price floor would have been binding, on average, U.S. producers would have gained $138 million and Mexican producers would have lost $218 million. However, total Mexican welfare would have actually increased by $11.5 million. Furthermore, the average price floor that would have maximized total Mexican welfare over that period is $22.76/cwt. Also, under certain supply and demand elasticity conditions, the average price floor that would have maximized joint U.S. and Mexican producer welfare over that period is $21.91/cwt. The latter two estimates are both close to the actual price floor agreed to in the 2014 Suspension Agreement. 相似文献
