Despite selling at substantial discounts, private placements of equity are associated with positive abnormal returns. We find evidence that discounts reflect information costs borne by private investors and abnormal returns reflect favorable information about firm value. Results are consistent with the role of private placements as a solution to the Myers and Majluf underinvestment problem and with the use of private placements to signal undervaluation. We also find some evidence of anticipated monitoring benefits from private sales of equity. For the smaller firms that comprise our sample, information effects appear to be relatively more important than ownership effects.

The price formation process of JASDAQ IPOs is more transparent than in the United States. The transparency facilitates analysis of important issues in the IPO literature—why offer prices only partially adjust to public information and adjust more fully to negative information, and why adjustments are related to initial returns. The evidence indicates that early price information conveys the underwriter's commitment to compensate investors for acquiring and/or disclosing information. Offer prices reflect pre‐IPO market values of public companies and implicit agreements between underwriters and issuers that originate well before the offering. Underadjustment of offer prices is substantially reversed in the aftermarket.

We use the IPOs of supply-chain partners as precipitating events and test for positive spillovers on private firms (the “IPO spillover hypothesis”). A trading partner’s IPO may benefit its suppliers through increased demand and its customers by reducing an input-related growth constraint. A newly public firm may also transmit additional liquidity to trading partners through trade credit practices. Using Japanese data on important relationships between IPO firms and their private suppliers and customers, we find that suppliers and customers experience significantly higher rates of growth in revenue, cash balances, and PP&E than do other private firms. The paper appears to be the first to document real and financial effects of positive liquidity shocks on supply-chain partners.
