货币供给、通货膨胀和粮食价格波动互动关系研究

在VAR模型和方差分解基础上,利用1997年以来的月度数据,分析货币供应量、通货膨胀和粮食价格之间的关系。结果显示：通货膨胀对粮食价格有显著影响,存在货币供应量、通货膨胀到粮食价格变动这一传导途径,同时发现通货膨胀有较强的自身惯性,通过抑制粮食价格来控制通货膨胀是无效的。     

Do oil tariffs lower wages?

An oil tariff has potential to alter the pattern of production and income distribution across productive factors. This paper use a general equilibrium model of production and trade with inputs of capital, labor, and international energy to examine the effects of an oil tariff. Under a range of conditions, higher energy prices created by oil tariffs would lower the ratio of wages to capital rents, and production of labor intensive goods would fall. This paper concentrates on the potential of oil tariffs to alter patterns of production and income distribution.     

The value of 1800 MHz and 2100 MHz spectrums in India and implications for auction design

The sequence of events leading up to the upcoming auction of 1800 MHz spectrum in India has led to the auctions acquiring an extraordinary significance for the future of the Indian mobile industry. A key feature of the auction design proposed by the regulator TRAI is the benchmarking of the reserve price of 1800 MHz to the price of 2100 – 3G spectrum revealed in the 2010 auction. In the context of the low number of LTE devices available and the fragmentation in the 1800 MHz band, this paper proposes reducing the duration of spectrum holding to ten years (from the current level of twenty years), and calibrating the reserve price of 1800 MHz with its value with GSM deployment. An economic model is used to compute the value of startup and incremental 1800 MHz spectrum. The estimated values are shown to differ from the value of 2100 MHz spectrum at a pan-India level and also in their distribution across circles. A new set of reserve prices are computed based on the estimation. The estimated values are also shown to be close to the AGR-adjusted price revealed in the 2001 auction. A reserve price based on the 2001 auction is also provided. Concomitant features of the auction are suggested to give coherence to the auction design.

华北地区近期用电量与经济增长反向的分析

分析了华北地区2009年一季度用电量负增长与经济正增长的原因。结论为投资和消费的高位增长支撑了经济增长的较高水平;出口和以高耗能为主的重工业产品产量的快速下滑是用电量负增长的主要原因,大宗商品价格暴跌后的去库存化过程加剧了这种反差。金融危机时期用电量负增长而经济正增长的反向现象是华北地区高耗能工业为主经济结构的必然反映。     

Reconsidering the Relationship between Inflation and Relative Price Variability

It has long been popularly believed that the relationship between inflation and relative price variability (RPV) is positive and stable. Using disaggregated CPI data for the United States and Japan, however, this study finds that the relationship is neither linear nor stable over time. The overall relationship is approximately U‐shaped around a nonzero threshold inflation rate. RPV therefore changes not with the inflation rate per se, but with the deviation of inflation from the threshold inflation rate. More importantly, the relationship is by no means stable over time but instead varies significantly in a way that coincides with regime changes of inflation or monetary policy. The relationship was positive during the period of high inflation of the 1970s and the early 1980s, as has been documented by a number of previous studies, whereas it takes a U‐shape profile during the Great Moderation. The results are robust to the use of core inflation, which excludes the traditionally volatile prices of food and energy. This paper then presents a modified version of the Calvo‐type sticky price model to describe the observed empirical regularities. Simulation experiments show that the modified Calvo model fits the data well, and that the underlying relationship hinges upon the degree of price rigidity, which is systematically related to inflation regime. For countries and periods with low inflation rates, the relationship takes a U‐shape as price adjustment is more sticky. In a high‐inflation environment, when price setting becomes more flexible, the U‐shaped profile vanishes.
