We study an intertemporal asset market where insiders coexist with “non‐fundamental” speculators. Non‐fundamental speculators possess no private information on fundamental values of assets, but have superior knowledge about some aspect of the market environment. We show that the entry of these (rational) speculators can lead to reductions in market liquidity and in the information content of prices, even in an efficient market. Also, equilibrium trades display patterns of empirical interest. For example, speculators appear to chase trends and lose money after market “overreactions,” while insiders trade as contrarians and profit after such overreactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
