Abstract

This study examines how service quality shapes purchase decisions in traditional culinary businesses, emphasizing the mediating roles of trust and word-of-mouth (WOM). Adopting a quantitative design that combines descriptive and explanatory approaches, we surveyed visitors to traditional foodservice establishments. Data were analyzed with PLS-SEM to test the measurement and structural models. The outer model met standard reliability and validity criteria (indicator loadings ≥ 0.60, CR ≥ 0.70, AVE ≥ 0.50). Structural results show that service quality, trust, and WOM each exert significant direct effects on purchase decisions. In addition, service quality indirectly influences purchase decisions through trust and WOM, indicating partial mediation. Overall explanatory power for purchase decisions is substantial, suggesting the model captures the key mechanisms that convert service experiences into buying choices. The findings underscore that improving frontline reliability, responsiveness, and assurance enhances customer trust, which, together with positive WOM including community and group interactions amplifies purchasing outcomes. Practically, managers of traditional culinary businesses should prioritize service-process excellence, transparent value cues, and community-based engagement programs to cultivate trust and stimulate advocacy. The study contributes by simultaneously modeling trust and WOM as mediators in a traditional culinary context and by providing actionable guidance on service strategies that sustain competitiveness in increasingly crowded foodservice markets.

Abstract

This study examines the determinants of regional economic performance with a particular focus on the roles of democracy and investment as key drivers of economic development in South Sulawesi. Using panel data from 24 districts and municipalities over the 2021–2023 period, this research analyzes how variations in political governance, investment flows, and structural economic characteristics shape regional growth outcomes. The study employs a panel regression approach comparing Pooled OLS, Fixed Effects, and Random Effects models to obtain consistent estimations and identify the most appropriate specification for explaining regional economic dynamics. The analysis highlights the conceptual significance of democracy as an institutional foundation that influences policy effectiveness, government accountability, and stability, all of which contribute to a conducive environment for economic activity. Investment is also positioned as a critical economic instrument that supports productivity, technological diffusion, and industrial upgrading. The findings indicate that the relationship between democracy, investment, and regional economic performance is not uniform across regions, reflecting differences in institutional capacity, labor quality, and industrial structure. Furthermore, the results emphasize that democratic governance and investment inflows operate as complementary forces: improvements in democratic quality can strengthen investor confidence, while investment outcomes can reinforce governance legitimacy by generating economic benefits. This study provides theoretical and empirical insights into how these variables interact in shaping regional development trajectories. The implications of this research underscore the need for region-specific strategies that integrate institutional strengthening, targeted investment policies, and human capital development to achieve sustainable and equitable economic growth.
