Inequality has often been explained by stable individual traits or by the structural features of labor markets. This study argues that we also should consider task involvement when we account for labor market inequality. Three mechanisms derived from experimental research link task involvement to performance: individuals involved in tasks are more focused on the work process, are more dedicated to mastery and problem-solving, and have stronger product quality perseverance. Despite the significance of task involvement as a motivation, its potential implication for labor market inequality is so far rather unacknowledged. We aim to develop its theoretical implications in the labor market context and test the expectation that task involvement is related to wage attainment by analyzing representative data for Sweden (LNU) and Europe (ESS). We theoretically locate our account within relational sociology, emphasizing that wage inequality is determined by interactions between worker attributes and the features of work organizations.
