Abstract

This study aims to examine the effects of brand image, price, and product quality on consumer purchase intention for Khasanah Sari Bread at the Dukuh Zamrud Branch. The research employed a descriptive quantitative method, using purposive sampling with 100 respondents who were potential consumers willing to purchase the product. Data were analyzed using multiple linear regression. The results show that brand image has a significant effect on purchase intention, indicating that a positive brand perception increases consumers’ willingness to buy. Price also has a significant effect, suggesting that an appropriate price consistent with perceived value supports purchasing decisions. However, product quality does not significantly influence purchase intention, implying that it is not the primary factor driving consumer decisions. Collectively, brand image, price, and product quality have a joint effect on purchase intention. In addition, external factors such as promotion, customer service, and customer satisfaction may also shape purchasing behavior. Therefore, businesses should prioritize strengthening brand image and pricing strategies to increase consumer interest.

Abstract

This research, which falls within the area of microstructure of financial markets, aims to compare liquidity with transaction costs, and determine the factors affecting volatility in small and large total asset energy companies in Indonesia. The use of data on companies with contrasting total assets contributes to providing investment portfolio management considerations for investors. The data used is taken from high-frequency stock price data per 30 minutes from Bloomberg subscribed. The illiquidity measurement method uses Amihud's Illiquidity, transaction costs use relative Bid-Ask Spread (BAS), and realized volatility is calculated using the square root of the realized variance. The use of 30-minute high-frequency stock price data can provide more detailed information. As a result, companies with small assets tend to have much greater stock price volatility, transaction costs, and illiquidity compared to companies with large assets. The factor affecting realized volatility is the volume of stock transactions. The greater the volume of stock transactions, the greater the volatility of stock prices. Keywords: High-Frequency Data; Realized Volatility; Amihud’s Illiquidity; Relative Bid-Ask Spread (BAS).

Abstract

Global uncertainty increasingly shapes financial connectedness in oil-dependent economies, particularly in the Gulf Cooperation Council (GCC), where Islamic and conventional markets operate side by side. This study examines the time-varying and directional spillovers between global uncertainty indicators and GCC Islamic and conventional financial indices during 2014–2024. Using the quantitative empirical approach, Dynamic Conditional Correlation GARCH (DCC-GARCH) model and the Diebold-Yilmaz Spillover Index, the analysis evaluates evolving correlations, directional spillovers, and rolling system-wide connectedness. The results show that Islamic and conventional GCC indices remain strongly correlated throughout the sample, while linkages with uncertainty indicators intensify during the 2014–2016 oil price collapse, the COVID-19 pandemic, and the Russia-Ukraine conflict. The rolling Total Connectedness Index (TCI) ranges from 55% to 80%, indicating substantial and crisis-sensitive interdependence. Oil price uncertainty and the GCC conventional index emerge as the main stock transmitters, with the conventional index occupying a central position through strong two-way spillover links. These findings imply that GCC financial stability is highly exposed to external uncertainty, highlighting the need for crisis-responsive risk management and diversification strategies.
