Financial System and Housing Price

The 2007/2008 US financial crisis is related to the securitization of mortgage loans and the housing-price boom and bust. In this article, we test the hypothesis that housing-price change is related to the development of the financial system. Using panel data for 23 countries from 1988 to 2012, we have found that the housing-price growth rate increases as the financial system moves a bank orientation to a market orientation. The policy implication is that the government should beware sudden increases in the capital market relative to the banking sector. Especially, more sophisticated financial supervision with respect to housing-price movement is required when a bank-based financial system progresses quickly to a market-oriented financial system.     

A Multiple and Partial Wavelet Analysis of the Oil Price,Inflation, Exchange Rate,and Economic Growth Nexus in Saudi Arabia

This article provides a fresh insight into the dynamic nexus between oil prices, the Saudi/US dollar exchange rate, inflation, and output growth rate in Saudi Arabia’ economy, using novel Morlet’ wavelet methods. Specifically, it implements various tools of methodology: the continuous wavelet power spectrum, the cross-wavelet power spectrum, the wavelet coherency, the multiple and the partial wavelet coherence to the annual sample period 1969–2014. Our results unveil that the relationships among the variables evolve through time and frequency. From the time-domain view, we show strong but non-homogenous linkages between the four variables. From the frequency-domain view, we uncover significant wavelet coherences and strong lead-lag relationships. From an economic view, the wavelet analysis shows that Saudi economy is still exposed to several global risk factors, which are mainly related to the oil market volatility, and the pegging of the local currency to the US dollar. Such risk factors strongly and negatively affect the real economic growth, exert more pressure on inflation, and substantially limit the freedom to pursue an independent monetary policy.     

On the importance of the long-term seasonal component in day-ahead electricity price forecasting with NARX neural networks

Daily and weekly seasonalities are always taken into account in day-ahead electricity price forecasting, but the long-term seasonal component has long been believed to add unnecessary complexity, and hence, most studies have ignored it. The recent introduction of the Seasonal Component AutoRegressive (SCAR) modeling framework has changed this viewpoint. However, this framework is based on linear models estimated using ordinary least squares. This paper shows that considering non-linear autoregressive (NARX) neural network-type models with the same inputs as the corresponding SCAR-type models can lead to yet better performances. While individual Seasonal Component Artificial Neural Network (SCANN) models are generally worse than the corresponding SCAR-type structures, we provide empirical evidence that committee machines of SCANN networks can outperform the latter significantly.

国际转让价格

国际转让价格的制定历来是跨国公司经营战略的一大难题。影响国际转让价格制定的因素有所得税差别、关税壁垒、竞争、通货膨胀、外汇管制、政治风险等。制定国际转让价格的方法分为以成本和以市价为基础两种,两种方法各有优劣。在实务中,跨国公司应联系自身的经营目标、组织结构、生产规模、定价策略以及各国经济、文化背景等因素加以选择。

人民币汇率走势分析

不同的劳动生产率和不同的现代通货膨胀和紧缩,在不同的国家体现了不同的商品标准定位价格。国际汇率是依据各国当时的单位法定纸币可以交换的商品价值量确定的,应当是各种法定纸币的各国商品标准定位价格的比例。根据这样的现代通货理论,可以分析人民币和美元、欧元、日元汇率的基本走势。     

股票抵押贷款预期回收率比较分析

股票抵押贷款是一种风险较大的产品.股票价值和收益的高波动性造成抵押品价值的回收率不稳定,进而影响贷款预期回收率,使得银行经营风险加大.为了有效估算股票抵押贷款回收率,本文运用预期回收率模型,借助中国色诺芬股票数据库和美国CRSP股票数据库信息,比较分析不同市场情况下预期回收率的区别.分析发现中国市场由于近几年股票波动率加强,整体预期回收率较低,而美国则相反;预期回收率与抵押率、违约概率都成负相关关系,而且预期回收率对于抵押率的变化非常敏感;60%贷款抵押率的设定在美国市场是可行的,而中国市场合理抵押率是54%左右.
