The authors show that, when some investors hold levered portfolios by engaging in margin borrowing, repeated rounds of trading can result in market instability--in the sense that prices can move rationally--even in the absence of any change in fundamentals. They show this with a simple model in...

A security design model shows that multinational firms needing to finance their operations should issue different securities to investors in different countries in order to aggregate their disparate information about domestic and foreign cash flows. However, if the firm becomes bankrupt,...

We provide a novel method for extracting estimates of realized pure price inflation from stock returns. The key is recognizing that pure price inflation should affect nominal returns of all traded assets by exactly the same amount. The popular Fama-French three-factor model is employed to purge...

A model of security design based on the principle of information aggregation and alignment is used to show that (i) firms needing to finance their operations should issue different securities to different groups of investors in order to aggregate their disparate information and (ii) each...

We argue that in the after-market trading of an IPO, the underwriting syndicate, by standing ready to buy back shares at the offer price (“price stabilization”), compensates uninformed investors ex post for the adverse selection cost they face in bidding for IPOs. This dominates ex ante...

A security design model shows that multinational firms needing to finance their operations should issue different securities to investors in different countries in order to aggregate their disparate information about domestic and foreign cash flows. However, if the firm becomes bankrupt,...

This paper models the strategic pre-tender offer share acquisition problem faced by potential bidders in takeovers. The model provides a rational explanation for the seemingly anomalous empirical evidence that the information about the impending tender offers is not fully conveyed through the...
