The structure and sustainability of current account deficit: Turkish evidence from regime switching

This study focuses on the current account deficit dynamics and sustainability, using data of the period between 1990:Q1 and 2014:Q2 in the context of Turkish economy. The main findings of the study can be put into two categories. The first category covers energy consumption, openness rate, gross domestic product, exchange rate and investments, which are the most important determinants of the current deficit. The second one asserts that sustainability is weak for Turkish economy; however, it is even weaker during the economic contraction. There is extensive literature about structure and sustainability of the current account deficit. However, many of the studies have analysed the sustainability of the current account deficits without considering the economic conjuncture. For this purpose, the study employs the Markov-switching method which is a non-linear time series model.     

Continuous time and nonparametric modelling of U.S. interest rate models

In this paper we compare the forecasting performance of different models of interest rates using parametric and nonparametric estimation methods. In particular, we use three popular nonparametric methods, namely, artificial neural networks (ANN), k-nearest neighbour (k-NN), and local linear regression (LL). These are compared with forecasts obtained from two-factor continuous time interest rate models, namely, Chan, Karolyi, Longstaff, and Sanders [CKLS, J. Finance 47 (1992) 1209]; Cos, Ingersoll, and Ross [CIR, Econometrica 53 (1985) 385]; Brennan and Schwartz [BR-SC, J. Financ. Quant. Anal. 15 (1980) 907]; and Vasicek [J. Financ. Econ. 5 (1977) 177]. We find that while the parametric continuous time method, specifically Vasicek, produces the most successful forecasts, the nonparametric k-NN performed well.

Cost analysis of material handling systems in open pit mining: Case study on an iron ore prefeasibility study

Selection of the optimal material handling system is one of the most significant decisions to be made in mineral industries. Rapid economic changes and technological improvements make cost analysis a complicated process. On the other hand, current low commodity prices have put a greater emphasis on cost reduction and process optimization to ensure viability of mining projects. In this article, two material handling systems, a semimobile in-pit crusher and conveyor systems (IPCC) and traditional truck and shovel systems (TS), are compared through the cost analysis of an iron ore prefeasibility study. Furthermore, robustness of the design parameters is evaluated through a sensitivity analysis to determine the relative importance of project parameters. Finally, risks associated with uncertain design parameters affecting cost analysis are assessed through Monte Carlo simulation. The results indicated that IPCC is more cost effective than TS.     

Who should practice price discrimination using rebates in an asymmetric duopoly?

Price discrimination is generally thought to improve firm profits by allowing firms to extract more consumer surplus. In competition, however, price discrimination may also be costly to the firm because restrictive incentive compatibility conditions may allow the competing firm to gain market share at the discriminating firm’s expense. Therefore, with asymmetric competition, it may be the case that one firm would let the other firm assume the burden of price discrimination. We investigate optimal segmentation in a market with two asymmetric firms and two heterogeneous consumer segments that differ in the importance of price and product attributes. In particular, we investigate second-degree price discrimination under competition with explicit incentive compatibility constraints thus extending prior work in marketing and economics. Focusing on the managerial implications, we explore whether it would be profitable for either or both firms to pursue a segmentation strategy using rebates as a mechanism. We identify conditions under which one or both firms would want to pursue such segmentation. We find that segmentation lessens competition for the less price-sensitive consumer segment and that this results in higher profits to both firms. A key to understanding this result is that segmentation leads to consumer remixing. We establish the key result that if firms are asymmetric in their attractiveness to consumers, the disadvantaged firm in our model is more likely to pursue a segmentation strategy than its rival in equilibrium. We then ask whether this result prevails in practice. To this end, we explore competitive segmentation empirically and are able to verify that disadvantaged firms indeed pursue segmentation through rebates with greater likelihood.     

Investigating the impacts of energy consumption,real GDP,tourism and trade on CO2 emissions by accounting for cross-sectional dependence: A panel study of OECD countries

The objective of this study is to analyse the long-run dynamic relationship of carbon dioxide emissions, real gross domestic product (GDP), the square of real GDP, energy consumption, trade and tourism under an Environmental Kuznets Curve (EKC) model for the Organization for Economic Co-operation and Development (OECD) member countries. Since we find the presence of cross-sectional dependence within the panel time-series data, we apply second-generation unit root tests, cointegration test and causality test which can deal with cross-sectional dependence problems. The cross-sectionally augmented Dickey-Fuller (CADF) and the cross-sectionally augmented Im-Pesaran-Shin (CIPS) unit root tests indicate that the analysed variables become stationary at their first differences. The Lagrange multiplier bootstrap panel cointegration test shows the existence of a long-run relationship between the analysed variables. The dynamic ordinary least squares (DOLS) estimation technique indicates that energy consumption and tourism contribute to the levels of gas emissions, while increases in trade lead to environmental improvements. In addition, the EKC hypothesis cannot be supported as the sign of coefficients on GDP and GDP² is negative and positive, respectively. Moreover, the Dumitrescu–Hurlin causality tests exploit a variety of causal relationship between the analysed variables. The OECD countries are suggested to invest in improving energy efficiency, regulate necessary environmental protection policies for tourism sector in specific and promote trading activities through several types of encouragement act.     

Employee satisfaction,customer satisfaction,and financial performance: An empirical examination

The purpose of this study is to examine the relationship between employee satisfaction and customer satisfaction, and to examine the impact of both on a hospitality company’s financial performance utilizing service-profit-chain framework as the theoretical base. Specifically, this study explores four major relationships: (1) the direct relationship between customer satisfaction and financial performance; (2) the direct relationship between employee satisfaction and financial performance; (3) the direct relationship between customer satisfaction and employee satisfaction; and (4) the indirect relationship between employee satisfaction and financial performance. Furthermore, this study examines the mediating role of customer satisfaction on the indirect relationship between employee satisfaction and financial performance. Data for this study was collected from employees, customers and managers of three- and four-star hotels. Structural equation modeling (SEM) with a two-step approach was utilized to empirically test the proposed hypotheses and the relationships between the constructs. Findings suggest that while customer satisfaction has positive significant impact on financial performance, employee satisfaction has no direct significant impact on financial performance. Instead, there is an indirect relationship between employee satisfaction and financial performance, which is mediated by customer satisfaction.     

Identifying the complex relationships among emotional labor and its correlates

Studied since the late 70s, emotional labor has received much attention especially in the service product context due to its presumed double edged wedge potential. Several job-related and person-related factors are postulated and tested for influence on emotional labor. However, the influence of culture, as a blanket factor, has been overlooked thus far. The aim of this study is to measure the complex relationships between emotional labor and a few of its antecedents and outcomes, including those previously measured and those missed such as culture. A structural equation modeling approach is used to identify the complex relationships inherent among emotional labor and other relevant factors, namely, personality, culture, work experience, job autonomy, and job satisfaction; job satisfaction was identified as being dependent on emotional labor and all other variables were identified as being independent. Findings revealed a negative relationship between emotional labor and job satisfaction and a surprising positive relationship between emotional labor and neuroticism but not extraversion, which are both defined by cultural values. Job autonomy, affected by work experience and extraversion, had a positive relationship with job satisfaction.     

Generation effects on work engagement among U.S. hotel employees

Drawing upon generational differences in work values and attitudes, this article examines work engagement of three generational cohorts using survey data collected from 677 customer contact employees in the hotel industry. Results of ANOVA and a series of moderated regression analyses indicate that levels of work engagement significantly differ depending on the generational membership of the employees. The effects of work engagement on turnover intention were significantly moderated by generational differences. Millennials were found to be a more distinct cohort from Gen Xers and Baby Boomers in terms of their level of work engagement as well as the relationship between work engagement and turnover intention.     

Analysis of children’s interest in books and their reading levels depending on the education status of family

The reading rate is an important indicator of the development level of a country. The fundamental condition of being a developed country is having a sufficiently educated workforce, which, in turn, is directly related to reading abilities and habits. In modern society, which has been termed the “information age”, the fastest way to acquire knowledge is through reading. Reading habits are initially formed within the family. Subsequently, the desired reading objectives can be achieved through the positive contribution of the school and the child’s environment. A child with developed reading skills will have the targeted accumulation of knowledge and will be suitably positioned to attain success in their future education and professional lives. The ability to reach this objective easily is directly related to the guidance and encouragement of families in this regard. The results of this study indicate that there is a strong correlation between the levels of education of parents in the Turkish Republic of Northern Cyprus and the reading habits that are given to children. For example, the results revealed that the children of 27 families with university and higher education levels read a total of 115 books, which is an average of 4.25 books per child on a monthly basis, whereas this figure was found to be 42 books, or an average of 1.82 in the 23 families with an education at high school level or below. The general purpose of the study is to determine the relationship between the reading habits of children and the education levels of their parents as well as the level of awareness of families in this respect. This is a qualitative study. The aim is to obtain in-depth and detailed data. The research is based on a case study, which is a qualitative research model. The examined case is that of North Cyprus.
