Price discrepancies, although at odds with mainstream finance, are persistent phenomena in financial markets. These apparent mispricings lead to the presence of ‘arbitrageurs’, who aim to exploit the resulting profit opportunities, but whose role remains controversial. This article...

This Paper develops a continuous-time two-sector model to study the economic effects of an import quota during the period of time over which it is imposed. One of the sectors is protected by a quota, which in our set-up manifests itself as an integral constraint on the flow of imports of the...

This paper explores the role of portfolio constraints in generating multiplicity of equilibrium. We present a simple financial market economy with two goods and two households, households who face constraints on their ability to take unbounded positions in risky stocks. Absent such constraints,...

This article studies the dynamic behaviour of security prices in the presence of investors’ heterogeneous beliefs. We provide a tractable continuous-time pure-exchange model and highlight the mechanism through which investors’ differences of opinion enter into security prices. In the...
