Abstract

This study aims to identify the pricing strategy used by a premium smartphone manufacturer when launching a new type by comparing actual price predictions with price predictions using a rating-based conjoint analysis method. The results of an analysis of 172 respondents from a university in Indonesia showed that the manufacturer use a combination of a skimming strategy, using product variants that are similar to types known to users beforehand, and a penetrating strategy through product variants that have never existed before. Analysis of respondents' evaluation of five smartphone attributes also shows that the feature that has the most part worth and the highest importance is network technology (5G or 4G) followed by internal memory capacity. The manufacturer in the US has set prices  that reflect part worths that are in line with RBCA prediction. In contrast, the distributor in Indonesia has set highest importance on the number of cameras. Managerially, these findings can be used by other smartphone manufacturers and distributors to when setting prices for future new products based on customer values. Theoretically, these findings indicate a significant difference between the conjoint analysis results and the producers' decisions that must be explained in the following research.

Abstract

Corporate governance and sustainability are key concerns for companies in Indonesia, particularly those operating in the banking sector, which have implemented corporate governance reforms to enhance the protection of shareholders’ and stakeholders’ interests. In addition, sustainability is required by regulators in the Indonesian banking sector, where its management is often a public consideration in assessing financial institutions, especially banks, as secure places to store their funds. The purpose of this study is to determine whether the implementation of good corporate governance and sustainable finance affects financial performance in banking. The independent variables used in this study are the size of the board of directors, the proportion of independent commissioners, CAR, Big 4 external auditors, and the proportion of credit for sustainable businesses. ROA serves as the dependent variable, while total assets are used as control variables. A purposive sampling method was applied to determine the study sample. Through this method, 47 general banks in Indonesia listed on the Indonesia Stock Exchange (IDX) were obtained. The research data was collected from the 2023 annual reports of all banks. The analytical method employed is multiple linear regression. The results of the study indicate that the CAR and sustainable finance variables have a significant positive relationship with ROA. This finding supports previous research that examined the relationship between CAR and sustainable finance with ROA, confirming that both variables have a significant positive influence. Accordingly, managers may focus on fulfilling these two variables to enhance ROA.

Abstract

This study analyzes the effect of service marketing mix elements—product, price, place, promotion, people, process, and physical evidence—on the purchase intention of prospective students toward University X in Bandung. The research addresses increasing competition among private universities and declining new student enrollment, which require more effective marketing strategies. A quantitative survey method was employed with 326 respondents from 60 high schools, vocational schools, and community learning centers in Bandung and the surrounding areas. Multiple linear regression analysis was conducted on 241 respondents in grades 10–12 who were aware of University X, with the results compared to those of 145 respondents from grades 11–12. In the overall analysis, price and people significantly influence purchase intention, while promotion shows a very weak effect. Product, place, and physical evidence show no significant effect. In the grade 11–12 segment, process is the only significant variable. The findings recommend marketing strategies focused on improving pricing and scholarship schemes, enhancing human resource competencies among lecturers, academic staff, students, and alumni, strengthening promotional efforts, and optimizing service processes. The study confirms that, in the higher education context, price, people, and process are dominant predictors of purchase intention, providing strategic insights for University X decision-makers.
