Asset Pricing in a Segmented Emerging Market

This paper investigates the effect of market segmentation on stock prices and returns in emerging Chinese markets. Under the assumption of infinite investment horizon and representative consumer, I formulate an Intertemporal Capital Asset Pricing Model (ICAPM) with restrictions on share ownership. The model posits that cross-section variations in the average excess returns between domestic A- and foreign B-shares depend on systematic risks as measured by shares' own market betas and betas with respect to the international equity markets. After correcting for errors-in-variable problem, I obtain econometric results consistent with the empirical predictions of ICAPM
