Self-selection and learning in sustainable innovations
Abstract: This paper investigates the mechanisms driving firms to locate in sustainable markets, focusing on self-selection patterns and the dynamics generated by the learning effects related to the development of sustainable innovations. The theoretical analysis is developed within a monopolistic competition framework with heterogeneous firms and consumers with varying sustainability preferences. Then, its core principles are empirically tested using firm-level data and a system of dynamic models, revealing a significant and positive relationship between past productivity and both the likelihood and intensity of sustainable innovations. Additionally, the outcomes demonstrate two sources of learning effects, one driving firms to persist in developing sustainable innovations, simultaneously increasing their quality, and another enhancing firm productivity once firms develop sustainable innovations. However, the learning returns on productivity are only obtained when there is an increase in the sustainability preferences of the rest of the economy. At their core, the market incentives driving firms to innovate sustainably are based on the trade-off between the costs associated with sustainable innovations and a firm’s ability to exploit their market returns. Then, the learning effects consolidate the long-term comparative advantages in sustainable and non-sustainable markets when the social focus on sustainability becomes more intense.
