In experimental economics, where subjects participate in different sessions, observations across subjects of a given session might exhibit more correlation than observations across subjects in different sessions. The main goal of this paper is to clarify what are session-effects: what can cause...

The phenomenon of p-hacking occurs when researchers engage in questionable practices that enable them to report findings as being statistically significant. I offer four models of p-hacking behavior – unconditional, strategic, greedy, and restrained – and explore the implications of each...

In various economic environments, people observe other people with whom they strategically interact. We can model such information‐sharing relations as an information network, and the strategic interactions as a game on the network. When any two agents in the network are connected either...

This paper proposes several statistical tests for finite state Markov games to ex- amine whether data from distinct markets can be pooled. We formulate homo- geneity tests of (i) the conditional choice and state transition probabilities, (ii) the steady-state distribution, and (iii) the...

Is the behavior of people consistent with the predictions of the Nash equilibrium and, in particular, the Minimax hypothesis? The existing literature have not reached a consensus about the answer to this question. This paper studies whether the soccer players involved in a penalty kick behave...
