This chapter provides an overview of different economics experiments, with a particular focus on different epistemic and non-epistemic interests underlying them. The chapter also discusses two types of philosophical interests in experimentation in economics, a general interest in the logic of inductive inferences and a more fine-grained interest in the divergence and convergence between economic and psychological perspectives in experimental practices in economics. Several experimental paradigms are used for illustrations, including public goods games, bargaining games, double auctions with the induced value method and random assignment method, and market entry games.
