房地产价格变动中的汇率因素分析

在构建了适合中国国情的房地产价格与汇率关系模型的基础上,利用该模型并结合2000年第三季度至2008年第二季度的最新数据,对中国35个城市房地产价格与汇率的关系进行实证研究。研究结果显示,汇率对房地产价格有负影响,这与理论和当前实际情况都比较相符,说明人民币汇率已能发挥一定经济调节的功能。

Markets for information: Of inefficient firewalls and efficient monopolies

In this paper we study market environments where information is costly to acquire and is also useful to potential competitors. Agents may sell, or buy, reports over the information acquired and choose their trades in the market on the basis of what they learnt. Reports are unverifiable – cheap talk messages – hence the quality of the information transmitted depends on the conflicts of interest faced by the senders. We find that, when information has a prevalent horizontal differentiation component, in equilibrium information is acquired when its costs are not too high and in that case it is also sold, though reports are typically noisy. The market for information is in most cases a monopoly, and there is underinvestment in information acquisition. We also show that regulatory interventions, in the form of firewalls, only make the inefficiency worse. Efficiency can be attained with a monopolist selling differentiated information, provided entry is blocked.     

Global Banks and Synthetic Funding: The Benefits of Foreign Relatives

This paper examines the effect of dislocations in foreign currency (FX) swap markets (“CIP deviations”) on bank lending. Using data from UK banks we show that when the cost of obtaining swap-based funds in a particular foreign currency increases, banks reduce the supply of cross-border credit in that currency. This effect is increasing in the degree of banks' reliance on swap-based FX funding. Access to foreign relatives matters as banks employ internal capital markets to shield their cross-border FX lending supply from the described channel. Partial substitution occurs from banks outside the UK not affected by changes in synthetic funding costs.

Selection of influential variables in ordinal data with preponderance of zeros

Presence of excess zero in ordinal data is pervasive in areas like medical and social sciences. Unfortunately, analysis of such kind of data has so far hardly been looked into, perhaps for the reason that the underlying model that fits such data, is not a generalized linear model. Obviously some methodological developments and intensive computations are required. The current investigation is concerned with the selection of variables in such models. In many occasions where the number of predictors is quite large and some of them are not useful, the maximum likelihood approach is not the automatic choice. As, apart from the messy calculations involved, this approach fails to provide efficient estimates of the underlying parameters. The proposed penalized approach includes ?₁ penalty (LASSO) and the mixture of ?₁ and ?₂ penalties (elastic net). We propose a coordinate descent algorithm to fit a wide class of ordinal regression models and select useful variables appearing in both the ordinal regression and the logistic regression based mixing component. A rigorous discussion on the selection of predictors has been made through a simulation study. The proposed method is illustrated by analyzing the severity of driver injury from Michigan upper peninsula road accidents.

论审计处罚中的违法所得

财经审计法律法规中的违法所得既可以表现为不应有而有,又可以表现为不应免而免。违法所得应该是已实现的经济收益。为体现《行政处罚法》立法精神和行政执法的效益、公平原则,认定和计算违法所得时应包括成本。没收违法所得应注意：没收较大数额的违法所得宜听证;对违法所得有明确合法权利请求人的应先行退还再予没收。
