This paper studies international equity markets when some investors have private information that is valuable for trading in many countries simultaneously. We use a dynamic model of equity trading to show that global private information helps explain US investors' trading behavior and...

This paper considers how the role of inflation as a leading business-cycle indicator affects the pricing of nominal bonds. We examine a representative agent asset pricing model with recursive utility preferences and exogenous consumption growth and inflation. We solve for yields under various...
