Can We Explain the Co-Evolution of Democracy and Market Economy by Adaptive Preferences?

In the research presented in this interview, the idea of adaptive preferences is applied to the co-evolution of democracy and market economy. CARL CHRISTIAN VON WEIZSÄCKER explains that the ideal of democracy and market economy though somehow antithetic are inter-dependent in a normative sense: While democracy provides freedom and stability, progress is only ensured by a market economy that allows for innovation.

Can We Maintain Normative Individualism when Allowing for Preferences to Be Adaptive?

Departing from the standard model of economics with the assumption that humans have fixed preferences, or tastes, more recent behavioral insights show that preferences are influenced by past consumption in a way that the status quo is often valued higher than alternatives. CARL CHRISTIAN VON WEIZSÄCKER adds this “adaptiveness” to the standard model of preferences and shows that this still allows performing standard welfare analysis. In showing that improvement paths are always non-circular, the altered model even delivers a foundation to do behavioral welfare economics.
