Can the Islamic bank be an emerging leader? A panel data causality analysis

This short note investigates the ability of Islamic banks (IBs) to play a leading role in revamping and driving conventional banking. To this end, we used a panel of 10 major conventional banks (CBs) and 10 IBs over the period 2006–2013. We applied panel regression tests and carried out a panel causality analysis. Our findings identified no significant causality effect from IBs to CBs and indicated that IBs are not able to play a role of leader.     

Curriculum assessment through a capstone course: a case study in hospitality and tourism programs

The purpose of this study was to develop a systematic process that other educational institutions and programs could follow to establish a consistent and accurate evaluation method for a capstone course. Hospitality industry professionals and hospitality management faculty were interviewed through focus-group discussions, and a post-focus-group survey was conducted to determine a weighted percentage for each of the nine determined content domains. A test blueprint for a hospitality management capstone course was developed to measure programmatic student learning outcomes based on the weighted domains determined through this study. The results provide a usable instrument for hospitality and tourism management programs to enhance their current assessment methodology.     

Do terror attacks affect the dollar-pound exchange rate? A nonparametric causality-in-quantiles analysis

While much significant research has been done to study the effects of terror attacks on stock markets, less is known about the response of exchange rates to terror attacks. We suggest a non-parametric causality-in-quantiles test to study whether (relative) terror attacks affect exchange-rate returns and volatility. Using data on the dollar-pound exchange rate to illustrate the test, we show that terror attacks mainly affect the lower and upper quantiles of the conditional distribution of exchange-rate returns, while misspecified (due to nonlinearity and structural breaks) linear Granger causality test show no evidence of predictability. Terror attacks also affect almost all quantiles of the conditional distribution of exchange-rate volatility (except the extreme upper-end), with the significance of the effect being particularly strong for the lower quantiles. The importance of terror attacks is shown to hold also under an alternative measure of volatility and for an important emerging-market exchange rate as well.     

Revisiting the labor supply effect of social security earnings test: New evidence from its elimination and reinstatement in Japan

We explore the labor supply effect of the social security earnings test in Japan on those aged 65–69 years through a combined examination of the elimination of the earnings test in 1985 and its reinstatement in 2002. We present evidence showing that the effects of changes in the earnings tests on the labor supply of the elderly are not symmetric, controlling for changes in the attributes of workers and firms. The repeal of the earnings test in 1985 did affect the earnings distribution of the elderly (especially for male), while its reinstatement in 2002 did not alter the earnings distribution.     

Measuring systemic risk with regime switching in tails

This paper motivates the importance of modeling nonlinearities in measuring systemic risk. I capitalize this motivation by generalizing the CoVaR approach proposed by Adrian and Brunnermeier (2016) to allow it switching between a high and a normal risk regime filtered from data.. Considering the U.S. large bank holding companies (BHCs), this paper shows that modeling regime changes in tails is capable of capturing both amplification and mean-reversion effects of an adverse shock to a bank's balance sheet on the banking system. Using the Kolmogorov–Smirnov test statistics with and without bootstrapping, I perform the significance test to identify systemically important financial institutions (SIFIs), and the stochastic dominance test to rank the identified SIFIs. The stochastic dominance test raises the concern that the CoVaR measure underestimates systemic risk contributions for SIFIs but overestimates for non-SIFIs. Finally, applying the BHCs' characteristics and housing market price to forecast the regime-switching systemic risk out-of-sample, I obtain from 4- and 8-quarter-ahead horizons a desirable countercyclical, forward-looking measure of systemic risk.

我国居民消费与经济增长的实证分析

消费对经济增长具有重大作用,居民消费作为消费需求的主体,其重要性更不能忽视。在面临金融危机的背景下,我国急需将经济增长从投资、出口转变为消费、投资、出口协调拉动。通过对1978——2008年的年度数据,对居民消费和经济增长进行实证分析,得出两者具有长期均衡关系,两者为双向的格兰杰因果关系;通过建立误差修正模型,得出两者短期之间的动态关系。最后,针对扩大内需提出四点建议。
