The Journal of Finance, 1994 Abstract The efficiency of security prices depends upon arbitrage, that is, trading based upon knowledge that the price of an asset is different from its fundamental value. (Although the term ‘arbitrage,’ strictly speaking, refers to an entirely riskless speculation, we use the term in the broader sense common among practitioners ...

Focusing on capital asset returns governed by a factor structure, the Arbitrage Pricing Theory (APT) is a one-period model, in which preclusion of arbitrage over static portfolios of these assets leads to a linear relation between the expected return and its covariance with the factors.

Market arbitrage versus agent arbitrage
Omega, 2004Abstract The present paper provides conditions for the consistency among different orderings which may be defined on sets of financial portfolios; in particular, a different reading key for some classical results is proposed. Besides arbitrage (whose impossibility is necessary and sufficient for consistency between the orderings based on prices and ...

The Arbitrage Pricing Theory (APT) is due to Ross (1976a, 1976b). It is a one period model in which every investor believes that the stochastic properties of capital assets’ returns are consistent with a factor structure. Ross argues that if equilibrium prices offer no arbitrage opportunities, then the expected returns on these capital assets are ...

, 1991 I report the results of nine experimental asset market sessions. The traded assets were contingent claims on two "states" with known state probabilities and identical aggregate payoffs across states. Since subjects could diversify away all idiosyncratic risks, this results in prices predicted to equal expected values regardless of risk preferences.

Approximate Arbitrage: The Arbitrage Pricing Technique
1991This chapter extends the concept of arbitrage to encompass approximate arbitrage and develops the arbitrage pricing technique (or APT); this may be interpreted as a generalisation of the version of the CAPM developed in Chapter 3.
