We develop a new theory of delegated investment whereby managers compete in terms of composition of the portfolios they promise to acquire. We study the resulting asset pricing in the inter-manager market. We incentivize investors so that we obtain sharp predictions. Managers are paid a fixed...

This paper reports on experimental tests of an instantiation of the Lucas asset pricing model with heterogeneous agents and time-varying private income streams. Central features of the model (infinite horizon, perishability of consumption, stationarity) present difficult challenges and require a...

We present results from an experiment where participants have access to a set of robots (automated trading algorithms), which they may deploy, launch, halt and replace at will, while still trading manually. We hypothesize that mispricing would be reduced. Yet, we observe equally large and...

We present experimental evidence that security prices do not respond to pressure from their own excess demand, unlike traditionally assumed in economic theory. Instead, prices respond to excess demand of all securities, despite the absence of a direct link between markets. We propose a model of...

This study tests the rationality of the decisions to purchase information, the informational efficiency of prices, and the optimality of the resulting allocations with a series of laboratory experiments in decentralized markets. The theory predicts that markets with dispersed information and...

We propose a Marshallian model for price and allocation adjustments in parallel continuous double auctions. Agents quote prices that they expect will maximize local utility improvements. The process generates Pareto optimal allocations in the limit. In experiments designed to induce CAPM...

We investigate how long an insolvent debtor can avoid default when survival is beneficial to creditors collectively, but individual creditors gain by forcing early repayment. Theory predicts that the debt is not rolled over and default is immediate. With 23 experimental sessions, default is...

Experiments constitute an indispensable tool to validate the building blocks of the theories which economists use not only to interpret events in the real world but also to inform regulation and economic policy. This is especially true in the context of multiple, interacting markets, which is...
