TY - JOUR PY - 2011// TI - Falsifiability JO - American economic review A1 - Olszewski, Wojciech A1 - Sandroni, Alvaro SP - 788 EP - 818 VL - 101 IS - 2 N2 - We examine Popper's falsifiability within an economic model in which a tester hires a potential expert to produce a theory. Payments are contingent on the performance of the theory vis-à-vis data. We show that if experts are strategic, falsifiability has no power to distinguish scientific theories from worthless theories. The failure of falsification in screening informed and uninformed experts motivates questions on the broader concepts of refutation and verification. We demonstrate an asymmetry between the two concepts. Like falsification, verification contracts have no power to distinguish between informed and uninformed experts, but some refutation contracts are capable of screening experts. (JEL B41)
