Type I error and test power of different tests for testing interaction effects in factorial experiments

A simulation study was conducted to investigate the effect of non normality and unequal variances on Type I error rates and test power of the classical factorial anova F‐test and different alternatives, namely rank transformation procedure (FR), winsorized mean (FW), modified mean (FM) and permutation test (FP) for testing interaction effects. Simulation results showed that as long as no significant deviation from normality and homogeneity of the variances exists, generally all of the tests displayed similar results. However, if there is significant deviation from the assumptions, the other tests are observed to be affected at considerably high levels except FR and FP tests. As a result, when the assumptions of factorial anova F‐test are not met or, in the case those assumptions are not tested whether met, it can be concluded that using FR and FP tests is more suitable than the classical factorial anova F‐test.     

Zone of tolerance for banks: a diagnostic model of service quality

Service quality has become an increasingly important factor for success and survival in the banking sector. Provision of high-quality service aids in meeting several requirements such as customer satisfaction and its consequent loyalty and market share, soliciting new customers, financial performance, and profitability (Cui, C.C., Lewis, B.R., & Park, W. (2003). Service quality measurement in the banking sector in South Korea. International Journal of Bank Marketing, 21(4), 191–201.). This paper presents the bank service quality measurement in its extended form. It deals with the concept of ‘zone of tolerance’ in judgments of service quality proposed by Zeithaml, Berry, and Parasuraman (1993, The nature and determinants of customer expectations of service. Journal of the Academy of Marketing Science, 21(1), 1–12.). The ‘zone of tolerance’ is recognized in the service quality literature as representing a range of expectations and an area of acceptable outcomes in service interactions. The present study describes the zone of tolerance for young customers’ service expectations and determines the customer satisfaction level for banks. The study focusses only on the youth market to formulate long-term strategies because young customers tend to keep themselves up to date with latest technological developments. A conceptual model BANKZOT is presented in this study, and the results demonstrate that evaluation of services can be scaled according to different types of expectations – ‘desired' and ‘adequate’ – and that customers use these two types of expectations as a comparison standard in evaluating bank services. The findings reveal that young customers have a narrow zone of tolerance with regard to the services provided by the banks. The results with respect to gap analysis reveal that there was a shortfall in the service quality provided by the banks in the sample, with the largest gap being found in tangibles and empathy of service quality dimensions. The results of exploratory factor analysis reveal that the SERVQUAL model is found to be uni-dimensional in this study. The results, managerial implications, and future research implications are discussed in detail.     

Impact of terrorism on tourism in Turkey: empirical evidence from Turkey

This article aims at investigating the causal impact of terrorist attacks on the tourism industry in Turkey based on the Autoregressive Distributed Lag (ARDL) bounds testing procedure for the period between 1986 and 2006. The ARDL bounds test reveals that tourism is in a long-run equilibrium level relationship with terrorism. The evidence obtained from the long-run and short-run parameter estimates indicates the existence of a negative causal effect of terrorism on tourism.

The day of the week effect on stock market volatility and volume: International evidence

This study investigates the day of the week effect on the volatility of major stock market indexes for the period of 1988 through 2002. Using a conditional variance framework, we find that the day of the week effect is present in both return and volatility equations. The highest volatility occurs on Mondays for Germany and Japan, on Fridays for Canada and the United States, and on Thursdays for the United Kingdom. For most of the markets, the days with the highest volatility also coincide with that market's lowest trading volume. Thus, this paper supports the argument made by Foster and Viswanathan [Rev. Financ. Stud. 3 (1990) 593] that high volatility would be accompanied by low trading volume because of the unwillingness of liquidity traders to trade in periods of high stock market volatility.     

CURRENCY CRISES IN EMERGING MARKETS: THE CASE OF POST‐LIBERALIZATION TURKEY

This article investigates the determinants of currency crises in Turkey. It analyzes the two major currency crises of 1994 and 2000–2001 in the light of the existing theoretical models. The present study uses logit, probit, and limited dependent models to explain the currency crises in the post–capital account liberalization era. The results obtained from the three approaches are generally consistent and the coefficients obtained for the explanatory variables generally have the same sign. The findings suggest that the currency crises in Turkey are associated with global liquidity conditions, fiscal imbalances, capital outflows, and banking sector weaknesses.     

The day of the week effect on stock market volatility

This study tests the presence of the day of the week effect on stock market volatility by using the S&P 500 market index during the period of January 1973 and October 1997. The findings shown that the day of the week effect is present in both volatility and return equations. While the highest and lowest returns are observed on Wednesday and Monday, the highest and the lowest volatility are observed on Friday and Wednesday, respectively. Further investigation of sub-periods reinforces our findings that the volatility pattern across the days of the week is statistically different.(JEL G10, G12, C22)     

Owner's Factor in Value-Based Project Management in Construction

Owner/client is a significant contributing party within the management of a project in construction. In addition to the payment of the bills related to the project, owner/client has duties and responsibilities such as selecting the professionals, making his requirements understood clearly by other parties, making decisions to recommendations and placing orders. Owner/client has to perform these duties and responsibilities at the right times and in correct ways to have the required quality and value for his/her investment. In performing his/her duties and responsibilities owner could introduce positive and negative contributions to the value of the constructed facility. Value-based project management concerns with owner's/client's value system and helps owner/client in performing his/her duties and responsibilities for the optimum positive contributions to the value of the constructed facility in construction. This paper highlights the principles of value-based project management in construction and investigates the impact of owner contributions to the value of a constructed facility in practice.
