(7) Capital not being able to move freely limits arbitrage opportunities and undermines the
law of one price.
The
Law of One Price in goods has been generalized, extended and developed into the wider concept of Purchasing Power Parity (PPP).
An alternative way to test capital market integration is based on idea of the
law of one price. Under the assumption that the expected EREIT return is determined by one of the four asset pricing models, the risk price(s) associated with the EREIT return should be equal to that(those) of other portfolio returns.
The
law of one price holds that two investment strategies that have exactly the same payoffs in the future should have the same value today.
Cointegration analysis allows us to test whether the price in one geographic market persistently differs from the price in the other market, taking arbitrage costs (transmission charges) into account, as a confirmation towards the
law of one price. Testing for persistent price differences offers a more realistic approach to examining the
law of one price than testing for whether the price in one market always equals the price in another (Woo, Lloyd-Zanetti and Horowitz, 1997).
* Contrary to intuition and expectation, net adjusted comparable prices often fail to reasonably reflect the "
law of one price" principle underlying the sales-comparison approach.
The so-called "
Law of One Price" is a special extreme version of this notion, where the price levels between different market chains are equal, except when a markup reflecting value is added (absolute version), or the rate of change in prices is equal (relative version).
Building on existing literature on cross-listing and using the data of listed Chinese companies from 1993 to 2010, Liu examines the relevance of the theories of bonding hypothesis, co-integration, and the
law of one price in the context of Chinese firms' cross-listing in the six major international capital markets.

The concept stems from the notion of the
law of one price: commodities should have the same price across the world when expressed in the same currency.
Arbitrage is closely associated with another key P3 concept: purchasing-power parity or the
law of one price. Arbitrage opportunities exist only where the
law of one price isn't operating.
