This paper provides a two-stage decision framework in which two or more parties exercise a jointly held real option. We show that a single party's timing decision is always socially efficient if it precedes bargaining on the terms of sharing. However, if the sharing rule is agreed before the exercise timing decision is made, then socially optimal timing is attained only if there is a cash payment element in the division of surplus. If the party that chooses the exercise timing can divert value from the project, then the first-best outcome may not be possible at all and the second-best outcome may be implemented using a contract that is generally not optimal in the former cases. Our framework contributes to the understanding of a range of empirical regularities in corporate and entrepreneurial finance.

This paper examines the cyclical nature of IPO activity in the UK. The results indicate a lead-lag relationship between IPO initial returns and volume. IPO volume is sensitive to recent changes in market conditions. There is evidence of industry concentration in hot markets, and firms raise more equity during these periods. Overall, IPO waves in the UK share similar characteristics with those in the US. The findings are consistent with rational explanations of IPO waves. However, explanations based on investor sentiment and market timing cannot be ruled out, since there is a strong positive relationship between IPO volume and the market's price-to-book ratio.

We model the dynamics of going public within an IPO wave. The model predicts that firms with better growth opportunities can find it optimal to go public early and accept underpricing of their issues to signal quality. Data supports this prediction as, on average, early movers underprice their issues significantly more and we show that leaders (early movers with high underpricing) obtain much higher valuations when going public than other IPO firms. Furthermore, after going public, leaders invest significantly more, their sales grow faster, and their profitability remains higher compared to other IPO firms.

We analyze the anatomy of IPO waves in China and Hong Kong and draw comparisons with the US IPO cycles. The lead-lag relationship between IPO initial returns and IPO volume observed in the US is absent in these two Asian markets. Similar to the US, IPO volume in Hong Kong is sensitive to changes in market conditions and exhibits seasonal variations. In sharp contrast, however, Chinese IPO activity is much less responsive to past market returns and volatility. Surprisingly, hot markets still emerge in China, not because of market forces as in the US and Hong Kong, but due to regulatory choices.
