We report a laboratory experiment examining how demand for exchange-traded fund (ETF) index products affects the prices and trading volume of assets. We compare an environment where the ETF index includes all assets against an environment where a redundant asset is excluded from the index. We find that (i) subjects place significant value on the ET...

Absent coordinating signals from an exogenous benevolent agent, can an efficient correlated equilibrium emerge? Theoretical work in adaptive dynamics suggests a positive answer, which we test in a laboratory experiment. In the well-known Chicken game, we observe time average play that is close to the asymmetric pure Nash equilibrium in some treatme...

We design an experiment to study how reversible entry decisions are affected by public and private payoff disclosure policies. In our environment, subjects choose between a risky payoff, which evolves according to an autoregressive process, and a constant payoff. The treatments vary the information disclosure rule on the risky payoff, such that in...

We examine how exchange traded funds (ETFs) affect asset pricing, and turnover in a laboratory asset market. We focus on behavior in secondary markets with or without ETF assets and whether there is zero or negative correlation in asset dividends. In the latter case, the diversification benefits of ETFs are most salient. We find that when the divid...

We study the efficiency of dynamic portfolio choices using the nonparametric methods of Dybvig (1988) and Post (2003). We compare a dynamic portfolio task against an equivalent static Arrow-Debreu problem under two alternative environments: (1) nonpooled with $$2^T$$ terminal states and (2) pooled with $$T+1$$ unique terminal states. The results...

We present an endogenous-timing conflict game of incomplete information under strategic complementarity. The model predicts multiple equilibria, in which the outcome follows either a simultaneous move game (Baliga and Sjöström, 2004) or a sequential game, which improves social welfare. We study the three families of games in the laboratory using ge...

We conduct a learning to forecast asset pricing experiment that assumes that financial advisors and professional forecasters attract more investors when their price forecasts are more accurate. The competition between forecasters implies that the impact of their forecasts on realized market prices evolves endogenously. We investigate how these endo...

We test in a controlled laboratory environment whether traders in a bilateral exchange internalize the impact of their actions on market prices better than in a large market. In this model, traders choose asset holdings, constrained by a technology frontier. Next, each trader experiences a random shock which makes only one type of asset profitable....

We apply standard evolutionary dynamics to study trader participation in three competing market formats —call market (CM), posted offer (PO) and decentralized market (DM). In our framework, heterogeneous buyers and sellers seek to transact a homogeneous good, which can be done by allocating their time among three different market formats. Our resul...

We conduct an experiment to determine whether market structure affects financial intermediary behavior. The intermediaries (Agents) are perfectly informed regarding project types and can recommend that their clients (Principals) either proceed or discontinue a project. Intermediaries earn revenues only when they recommend proceeding with the transa...

We use an experimental approach to study the effect of market structure on the incidence of misreporting by credit rating agencies. In the game, agencies receive a signal regarding the type of asset held by the seller and issue a report. The sellers then present the asset, with the report if one is solicited, to the buyer for purchase. We find that...

We study the impact of Chinese supply and demand shocks on Peruvian firm-product exports. Our results indicate that Chinese competition has a positive and significant effect on Peruvian firm exports, which suggests that firms are either (1) concentrating on markets where competition is tougher, (2) increasing R&D efforts, and/or (3) benefiting from...
