Beta, as measured by the Capital Asset Pricing Model (CAPM), is widely used for pricing stocks, determining the cost of capital, and gauging the extent to which markets are integrated. The CAPM model assumes that equilibrium conditions prevail. The choice of which market portfolio to use in the regression – the home country or global index – depends on the level of global market integration. We...

Rapid advances in technology are driving dramatic changes in capital markets. To compete effectively, market participants need to form alliances and provide integrated services. In this context, web services are an emerging integration technology, and with an emphasis on open standards and greater flexibility, may provide benefits over existing integration practices.

Using a costly search model we derive the equilibrium deal...
