Joint estimation using revealed and stated preference data: An application using a national forest

We combine contingent behaviour with travel cost data to estimate the change in the recreational use value of a National Forest due to quality and price changes. Instead of the usual improvement scenario, a hypothetical deterioration in the conditions of the forest due to a fire is considered. A dataset containing five observations for each respondent enabled the estimation of three models for which the number of scenarios differed. The results show that visitors are sensitive to price and quality changes and that in the forest fire scenario the intended number of trips would be reduced and that respondents would experience a welfare loss. Signs of inconsistency between preferences expressed by revealed and intended behaviour were found. This research also provides some indications that strategic bias affects answers to price changes.     

Income based price subsidies and parallel imports

We present a policy game where a Rich country has a higher ability than a Poor country to commit to certain elements of health policy such as providing income related price subsidies and allowing parallel imports (PI). When allowing PI is not a choice for the Poor country, the Rich country allows PI and both countries provide a subsidy to their poorer buyers as the subgame perfect equilibrium policies. However, when the Poor is able to PI a different equilibrium may arise. We show that the ability of the Poor to allow PI might increase welfare in this country even if it is never implemented. We also prove that as the Poor country gets richer, it will not be in their best interest to sign an agreement with the Rich to commit to not allowing PI.     

Exchange rate movements and foreign direct investment (FDI): Japanese investment in Asia, 1987–2008

The paper estimates the impact of exchange rate movements on foreign direct investment (FDI). By using the panel data of Japanese FDI flows to nine dynamic Asian economies during 1987–2008, the paper finds that (i) FDI declined with a depreciation of the yen against host country currencies; (ii) it increased with exchange rate volatility; and (iii) it was little affected by the Asian financial crisis, especially when disguised financial flows were removed from the data. A novel result concerns the negative response of FDI to the third moment of monthly exchange rate changes: the volume of FDI was smaller when the distribution was positively skewed (i.e., when the yen was biased towards relatively large depreciation shocks). If skewness proxies for expected mean-reverting changes, this supports the idea that source country investors care about the future stream of revenues and returns denominated in their own currency. These results are robust, with other standard control variables having statistically significant coefficients with expected signs.     

地方高校文化与区域文化互动发展模式--文化素质提升工程的有效路径

Estimating DSGE models across time and frequency

Using a wavelet-based decomposition, this paper exploits the information in the data usually employed in the estimation of DSGE models. A simple New Keynesian model featuring price and wage rigidities is estimated for the United States across different frequencies. The estimations indicate that most structural parameters exhibit a frequency-dependent behavior. The impulse response functions also indicate frequency-dependent responses of output to the exogenous shocks. For lower frequencies, there are more persistent effects, especially for preference and technology shocks.     

A multidimensional analysis of poverty in China from 1991 to 2006

Most studies have reported non negligible improvements for China in terms of poverty during the last three decades. However, this result is potentially hampered by two limitations. First, it may be contingent to the specific choices made regarding the poverty line and the poverty indices used for the analysis. As a consequence, it may collapse if one uses alternative poverty lines or poverty measures. Second, it results from a focus on the sole monetary aspects of poverty. As income does not cover all facets of well-being and since the relationship between these two concepts are quite fuzzy, it may be worth using a broader view of well-being, hence opting for a multidimensional approach of poverty analysis. In the present paper, these two issues are addressed using multidimensional stochastic dominance procedures on the joint distribution of income, education and health in seven Chinese provinces.     

从美国房价走势透视中国房地产市场走向

内容文章从量化分析的角度出发,研究了全美50个州和哥伦比亚特区房价指数序列的记忆性特征,发现各州房价指数序列均具有一定程度的长记忆性.同时,我们对50个州房价指数记忆参数的估计值进行了聚类分析,由此发现各州房价指数的记忆性呈现出一定的地区聚集性特征,而且还与地区的人口密度存在一定关系,从而为宏观政策制定者在决定房价调控措施的时候提供了有益的新思维,可使楼市更加健康稳定地发展.此外,文章的研究结果对于解决我国房地产市场目前存在的巨大泡沫问题提供了一个全新的视角     

Towards a Measure of Core Inflation using Singular Spectrum Analysis

This paper constructs a number of possible core measures of inflation using singular spectrum analysis (SSA). Annual changes in monthly inflation are decomposed into its trend, oscillatory and noise components in order to develop an understanding of the trend and cyclicality in South African headline inflation. Three cyclical components with differing amplitude and frequency are identified. The trend and cyclical components of inflation are found to be a good approximation of core inflation, the inertial part of inflation. These core measures are compared with other candidate core measures based on the properties of a good core inflation measure. Generally, the SSA measures outperform commonly used measures of core inflation based on both in‐ and out‐of‐sample performance.

基于Supermap和Google earth的城中村改造面积估算——以广州市海珠区为例

城中村多存在于经济发达的城市，广州是珠三角地区的发达城市之一，在广州市区内，共存在138个城中村。城中村的存在为广州市内广大的外来工作人员提供了价格低廉的住房。可是，近10年来，城中村的问题日益凸显，促使广州市政府对城中村进行大规模的整治和改造。对广州城中村的面积进行估算，能够得到广州城中村的面积、区位等数据。本文对广州城中村的面积估算方法进行探讨，并使用Supermap Deskpro软件和Google earth软件对广州市海珠区的城中村面积进行估算，从而了解广州城中村的规模、分布区位及其分布特征，为城中村的改造和整治提供基础数据。
