The Impact of After-sales Service Quality on Customer Satisfaction and Customer Loyalty of Middle-upper Class Landed Housings

Abstract: Nowadays, good products are not sufficient. Market competition requires a good after-sales service. After-sales service quality has been identified as a source of revenue and competitive advantage. While other industry sectors have readily paid attention to after-sales service quality, little study has been done on the effectiveness of after-sales service quality in the field of real estate. This study aims to explore the relationship among after-sales service quality, customer satisfaction, and customer loyalty. Especially, we want to confirm the impact of after-sales service quality on customer satisfaction and customer loyalty of middle-upper class real estate in Surabaya. This research was conducted by survey on 170 respondents from four housing complexes in Surabaya, i.e. Pakuwon City, Citraland, Bukit Darmo Golf, and Graha Family. The data was examined by using structural equation modeling (SEM). Through data analysis we confirm the positive correlation between after-sales service quality and customer satisfaction, the positive correlation between customer satisfaction and customer loyalty, and the direct and indirect relationships between after-sales service quality and customer loyalty. The practical implication of this study provides assurance to real estate management on the effectiveness of after-sales service quality in maintaining old customers and encouraging new consumers.

The influence of female director on the probability of companies experiencing financial distress

Abstract: This study aims to determine the effect of Female Director on the Probability of a Company Experiencing Financial Distress. Springate model is used to predict the probability of a company experiencing financial distress. This study compares the effect of female director on the probability of a company experiencing financial distress without control variables and using control variables. The control variables in this study are board size, firm size and leverage. The population in this study were manufacturing companies listed on the Indonesia Stock Exchange in the period 2013-2018. The samples in this study were 27 companies. The results of this study indicate that female directors have no significant effect on the probability of a company experiencing financial distress. By using control variables, it is shown that female directors do not significantly influence the probability of a company experiencing financial distress with the control variables such as board size, firm size, and leverage.

Daylighting performance of horizontal light pipe branching on open plan office space

Abstract: For daylighting purpose, office buildings should have a shallow plan and increase the ratio of surface to building’s volume. However, intensive use of air-conditioning drives office building’s plan to be deep with a minimum surface to volume ratio. This leads to the presence of areas that have insufficient daylight level at the work plane. Considering limitations of some daylighting methods in distributing daylight to these areas, Horizontal Light Pipe (HLP) was selected. The aim of this research was to evaluate and explain the effect of HLP branching on daylight quantity and distribution inside open plan office space. Experimental with simulation as a tool was used as the research method. HLP branching’s uniformity ratio, illuminance and Daylight Factor were compared with unbranching HLP, simultaneously with daylighting standards. Results showed that office space with HLP-L branching had higher daylight level than HLP-T branching, 296 lux and 295 lux, HLP-L and HLP-T, respectively. However, HLP-T branching distributed daylight more evenly than HLP-L branching, with uniformity ratio as 1.49:1 and 1.50:1, HLP-T and HLP-L, respectively. Both of them met the illuminance target value and uniformity at work plane. Light’s deflection and improvement amount of opening distribution decreased average illuminance and Daylight Factor up to 3.59%. Those also decreased uniformity of daylight inside the space.

Information Asymmetry in the Post-IFRS Adoption Period: Evidence from Developing Countries

Abstract: bjective - The adoption of IFRS aims to reduce the level of information asymmetry. Prior studies conducted in developed countries prove that the adoption of IFRS enhances transparency and diminishes information asymmetry. However, in developing countries with a low level of openness, limited regulation, and more centralized ownership, the ability of IFRS to reduce information asymmetry remains unknown. To address this issue, this study aims to investigate whether IFRS adoption will reduce information asymmetry in some developing countries in South East Asia. Methodology/Technique - This research is applied in three developing countries: Indonesia, the Philippines and Thailand. Information asymmetry is proxied by the cost of capital using the Easton model (2004) and a bid-ask spread. Listed firms from the three countries are selected as the research sample resulting in 5.313 firm-years for the period between 2007 and 2016. Findings - This study concludes that the adoption of the IFRS decreases information asymmetry in developing countries. These finding confirm that the benefit of the adoption is the same as in developed countries, despite the level of law enforcement in developing countries being lower. Managers, standard authorities and investors must note that the IFRS conveys benefits to the market, which increases transparency by asking lower returns and valuing company stocks appropriately. Novelty - This study examines the benefits of the adoption of the IFRS in reducing information asymmetry in some emerging countries to enhance the generalization of the results from prior studies that are mostly conducted in developed countries.

A Multi-Product EPQ Model with Discrete Delivery Order: A Langrangean Solution Approach

Abstract: In this paper, a multi products EPQ vendor buyer integrated model in Just in Time (JIT) philosophy with budget constraint is developed. Buyer asks the vendor to deliver products in small batch with discrete delivery order. The problem is modeled as a Mixed Integer Non Linear Program (MINLP) with constraint. Langrangen method and branch and bound procedure are developed to solve the problem. One numerical example is shown to illustrate the model and solution procedures and the result shows that the Lagrangean solution approach can derive global optimum solution.
