Abstract

This study aims to analyze the factors influencing the occurrence of claims in credit insurance at PT Asuransi Kredit Indonesia (Askrindo) using a binary logistic regression approach. The analysis was conducted on 14,331 insurance policy records from the period 2021 to 2024, encompassing variables such as regional classification, insured value, premium, gender, age, credit type, insurance duration, and business source. The results reveal that region, debtor age, and credit type have a statistically significant effect on claim probability, with Region III and debtors aged above 55 exhibiting the highest likelihood of claim occurrence. In contrast, insured value and premium show no significant impact, indicating that the current underwriting process may not adequately reflect default risk. The logistic regression model successfully identified seven significant variables and passed all model fit and multicollinearity tests. These findings carry strategic implications for strengthening credit risk management, particularly in refining underwriting policies, improving debtor creditworthiness assessments, and ensuring financial sustainability amid increasing exposure to MSME guarantee programs.

Abstract

Introduction: This study aims to identify the causal relationship between the Indonesian stock market and the stock markets of BRICS countries (Brazil, Russia, India, China, and South Africa) during the early period of the COVID-19 pandemic in 2020. The pandemic triggered global uncertainty and led to increased volatility in international financial markets, including Indonesia. Method: This quantitative research utilized secondary data comprising daily closing prices of stock indices: IHSG (Indonesia), BOVESPA (Brazil), RTS (Russia), BSE (India), SSE (China), and FTSE (South Africa), spanning from January to December 2020. These data were transformed into logarithmic daily returns. The analysis was conducted using the Granger causality test. Results: The results revealed a one-way causal relationship from the Brazilian and South African stock markets to the Indonesian market, a two-way relationship between the Russian and Indonesian markets, and no significant causality with the Indian and Chinese markets. These findings indicate that the Indonesian stock market is vulnerable to global market dynamics, especially those of the BRICS countries during crises. This research offers valuable insights for investors and policymakers in formulating risk management strategies.

Abstract

Assorted types of market anomalies occur when stock prices deviate from the prediction of classical asset pricing theories. This study aims to examine asset growth anomaly where stocks with high asset growth will be followed by low returns in the subsequent periods. This study, using Indonesia Stock Exchanges data, finds that an equally-weighted low-growth portfolio outperforms high-growth portfolio by average 0.75% per month (9% per annum), confirming existence of asset growth anomaly. The analysis is extended at individual stock-level using fixed-effect panel regression in which asset growth effect remains significant even with controlling other variables of stock return determinants. This study also explores further whether asset growth can be included as risk factor. Employing two-stage cross-section regression in Fama and Macbeth (1973), the result aligns with some prior studies that asset growth is not a new risk factor; instead the anomaly is driven by mispricing due to investors’ overreaction and psychological bias. This result imply that asset growth anomaly is general phenomenon that can be found at mostly all stock market but in Indonesia market asset growth anomaly rise from investors’ overreaction, instead of  playing as a factor of risk.

Abstract

Introduction/Main Objectives: This paper examines the relationship between market uncertainty and asymmetric information in the Indonesian energy sector from 2021 to 2024, using the World Uncertainty Index (WUI) as a measure of global economic and political uncertainty. Background Problems: The study is driven by heightened uncertainty due to major global events such as the COVID-19 pandemic and the Russia-Ukraine conflict, which have introduced significant volatility into the market. Novelty: This research uniquely focuses on the Indonesian energy sector, an underexplored area in global finance, and uses the World Uncertainty Index (WUI) to link global uncertainties with the performance of Indonesia's developing energy market. Research Methods: Employing a regression model, the study investigates the causal relationship between stock market volatility and asymmetric information. Results: The findings reveal that increased volatility negatively impacts market efficiency, indicating that uncertainty and information gaps hinder the market’s ability to fully reflect available information. Conclusion: the study highlights the significant impact of market uncertainty and asymmetric information on stock market volatility and efficiency in Indonesia’s energy sector, offering valuable insights for improving investment strategies and policy formulation in a volatile global environment

Abstract

The XYZ Institution/Agency, as a governmental institution, has the obligation to resolve debts resulting from financial losses. This study aims to analyze the influence of demographic, financing, and educational institution characteristics on the default of educational debt/student loan (State Compensation Claim for Breach of Service Agreement) at the XYZ Agency. To achieve this objective, the study utilizes data on debtors from 1983 to 2022 at the XYZ Agency and employs binary logistic regression analysis. The results of this study indicate that age and receivable value significantly affect the quality of the debtor's receivables. Specifically, debtors who are over 26 years old and have receivable values above IDR 200,000,000 are more likely to default. In contrast, gender and campus status do not significantly impact the default rates. These findings are expected to provide insights for the XYZ Agency in improving the management of state debts, particularly educational debts, and contribute to the development of policies related to debt management in the public sector. This study also provides a comprehensive overview of the variables influencing the default of educational debts at the XYZ Agency, with a focus on the State Compensation Claim (TGR) process at the XYZ Agency.

Abstract

Entrepreneurial intentions among undergraduates students need more indepth study to reveal entrepreneurial intention formation model, intention determinant variables, and how those variables interact each other in  the intention formation process and intention strength level. Personal attitudes and social norms are the most important variable influencing entrepreneurial intentions, besides perceived behavioral control. These three variables are the most important entrepreneurial intentions determinant variable  that each are directly influenced by personal beliefs. Prior research show gender gaps in entrepreneurial activity and there is a significant different entrepreneurial intentions formation process between gender. Entrepreneurship educations are aimed to change all personal beliefs to be more positive to entrepreneurial activity so we could find strong entrepreneurial intentions  among undergraduate students. Empirical test show that entrepreneurship education significantly influence personal attitude dan perceived behavior control to be more favorable in developing entrepreneurship education. Female students tend to value more on non monetary entrepreneurial benefits than male student. Entrepreneurship education strengthen each gender’ tendency to value more what they initially believe.

Abstract

This study examines the short-term reactions of six international stock markets to the announcement of the United States’ tariff policy using an event study methodology. Grounded in the Efficient Market Hypothesis, market responses are expected to reflect rapid price adjustments to new information, while the financial linkage perspective suggests that countries with stronger investment exposure to U.S. investors may react more intensely. To test these theoretical expectations, the analysis focuses on abnormal returns (AR) surrounding the event window of −3 to +3 days, with countries classified into high and low groups based on the level of U.S. Resident Securities Holding. The empirical results reveal significant abnormal returns across several high-holding countries, particularly Japan, which shows strong anticipatory reactions prior to the announcement and notable corrections afterward. Canada and South Korea also demonstrate early and coordinated responses. Conversely, low-holding countries exhibit weaker and less systematic reactions; South Africa shows delayed negative movements, while Thailand and Turkey display minimal sensitivity to the policy shock. These findings support both hypotheses: markets exhibit significant abnormal returns during the event window, and financial exposure to U.S. investors amplifies the speed and magnitude of market reactions. Overall, the study provides evidence that cross-border portfolio linkages play a meaningful role in transmitting the impact of U.S. trade policy to global financial markets. The results highlight the importance of financial integration as a channel of international shock propagation and offer insights for policymakers and investors managing risks in highly interconnected markets.
