We model financial innovations such as Exchange-Traded Funds, smart beta products, and many index-based vehicles as composite securities that facilitate trading common factors in assets' liquidation values. Through accessing a larger basket of assets in endogenously-chosen proportions, composite...

We investigate the impacts of the short-termism on multiple equilibria in a dynamic rational expectations equilibrium model. We find that short-termism is not the cause of equilibrium multiplicity but affects market quality of all equilibria. The liquidity, price efficiency and expected trading...

The competitive market is informationally efficient; people only need to know prices to implement a competitive outcome. However, the standard formulation of competition neglects any underlying market microstructure; prices—which provide all necessary information—are exogenous. This paper...

In economies with incomplete information, laissez-faire price competition is not, in general, constrained Pareto efficient. But which market structures are? We consider an environment in which firms have private information about costs and consumers make discrete choices over goods. Surveying an...

The continuous debate and research related to High Frequency Trading emphasises the importance of performing analysis on topics associated with the interaction of traders with different trading speeds, and the effects of this interaction on price efficiency and market quality. The aim of this...

This paper examines whether the outcome bias harms price efficiency in betting exchange markets. In soccer, the match outcome is an unreliable performance measure, as it underestimates the high level of randomness involved in the sport. If bettors overestimate the importance of past match...

The subject of our study is the trading infrastructure of government securities markets, which has undergone fundamental changes driven by the appearance of non-exchange electronic platforms and the rapid rise of their share in the trading volume of developed markets. The summary of the relevant...

We study a general static noisy rational expectations model, where investors have private information about asset payoffs, with common and private components, and about their own exposure to an aggregate risk factor, and derive conditions for existence and uniqueness (or multiplicity) of...

We consider Kyle's market order model of insider trading with multiple informed traders and show: if a linear equilibrium exists for two different numbers of informed traders, asset payoff and noise trading are independent and have finite second moments, then these random variables are normally...

Insurance markets are characterized by profound market imperfections. Insurance intermediaries reduce transaction costs and information asymmetries. From transaction cost economics, agency theory, and law and economics literature the hypothesis is derived that insurance brokers may provide more...
