<![CDATA[Household consumption among university lecturers is influenced by income, work experience, family size, and lifestyle, which reflects personal preferences and social factors. This study examines how income, work experience, and family size affect household consumption, with lifestyle as a mediating variable, among lecturers in Makassar. A quantitative explanatory design was employed, surveying 200 lecturers (100 from public and 100 from private universities) using structured questionnaires. Data were analyzed through Structural Equation Modeling with Partial Least Squares (PLS-SEM). Results show that income and work experience significantly influence lifestyle, while family size does not. Lifestyle strongly mediates the relationship between economic factors and household consumption, with indirect effects confirming that income and work experience affect spending through lifestyle. These findings underscore lifestyle as a critical behavioral channel linking personal economic factors to consumption patterns. The study contributes theoretically by supporting consumption and lifestyle models in behavioral economics and offers practical implications for universities and policymakers to consider income and lifestyle in designing welfare and financial literacy programs for lecturers.]]>
