Investor protection and institutional investors' incentive for information production

We exploit a quasi-experimental setting in India to empirically demonstrate that non-discretionary allocation of book-building initial public offering (IPO) shares incentivizes institutional investors to understate the value of IPO shares in the primary market, so they can acquire shares at a lower price in the secondary market. Our IPO underpricing framework, which disentangles the effect of institutional investors' incentive-associated with allocation policy, from the effect of underwriters' risk-associated with underwriting contract, demonstrates that underpricing in book-building IPOs underwritten with firm-commitment contracts in India is higher in the post-September 2005 non-discretionary allocation investor protection period, than in the pre-September 2005 discretionary allocation period. Conversely, underpricing in fixed-price IPOs underwritten with firm-commitment contracts is lower in the post-September 2005 investor protection period than in the pre-September 2005 period. Overall, our findings, which are robust to endogneity concerns, reveal a policy tradeoff between information production and investor protection.
