Experimentally studies competitiveness of markets with network effects under different assumptions of buyer behavior, separating individual lock-in from market-wide systemic lock-in.
By experimentally pairing game players with non-playing guessers, identifies random play motivated by unpredictability versus ambiguity aversion. Compares play patterns and predictability of players and guessers in a repeated matching pennies game.

In one-shot and repeated versions of O'Neill's zero-sum game, experimentally studies whether game-players value randomness of mixed-strategy play, contrary to theoretical indifference between pure and mixed strategies.
