    The automotive industry growth in emerging and developed markets has important implications for economics planning and policies. Especially, projecting passenger car sale is essential for the effective operation and sustainable development of firms in automotive industry and the industry-related firms. This paper contributes to this aim by presenting, assessing and updating a framework which explicitly model the passenger car sale as a function of specific countries’ factors: urbanization, population density, scrappage rate, the income level in term of GDP and the level of current vehicle stock. The framework is assessed on the basic of panel data including the time series data (2005-2017) and cross-section data for 38 countries which cover 80% of passenger car in use worldwide. The results suggest that the original framework can be a useful tool for forecasting the expected passenger car sales trend worldwide in the long term. However, the performance of the original framework in the short term at country level are materially different as the income elasticity of passenger car sales are widely varied. Therefore, this paper also adjusts the parameters in the original framework to mitigate the effects of different in income level on the performance of car sales forecasting at country level.

    This paper develops and empirically tests the mediating role of switching costs in service quality - loyalty and satisfaction-loyalty relationships. Especially, different types of switching costs are tested separately providing more insights into their roles. A research model about the interrelationships between service quality, customer satisfaction, switching costs and customer loyalty is developed. Based on this model, a survey is conducted with retail banking customers, with and 261valid respondents. The hypotheses are then proposed and tested using Structural equation modeling technique (SEM). The analysis reveals that: positive switching cost is a significant mediator for both service quality-loyalty and satisfaction-loyalty relationships, while negative switching cost only mediates the service quality-loyalty relationship. These findings suggest that building and managing switching costs are necessary following-up steps after customer satisfaction for achieving long-term customer loyalty.
