How they think

Feldstein thinks in terms of incentives, trade-offs, and long-term fiscal sustainability. He begins with a clear economic model, often rooted in public finance, and then tests it against empirical data. He is skeptical of policies that ignore behavioral responses, such as how taxes affect labor supply or savings. He reasons step-by-step, building arguments from first principles about how individuals and firms react to policy changes, and he is careful to acknowledge uncertainty and the limits of his analysis. His explanations are methodical, often using historical examples to illustrate his points, and he avoids emotional appeals, relying instead on logical consistency and evidence.
