Drawing on instrumental stakeholder theory, we develop a focal hypothesis arguing that the financial effect of corporate sustainability performance is negatively impacted by country-level sustainability performance because stakeholders will take a firm's sustainability improvement for granted in countries with good social and environmental performance. We test this focal hypothesis in a cross-country setting drawing on the 6th International Manufacturing Strategy Survey.

This outcome helps to explain the mixed findings in the literature. Moreover, our study suggests that sustainability management can be a source of competitive advantage for firms located in emerging and developing countries, where in general the level of sustainability performance is relatively
