Recent theories based on sequential financing and information signaling reveal a special role for warrants. Data from initial public offerings (IPOs) of stock-warrant units have been used to test the theories, and we extend the analysis to seasoned offerings. Consistent with predictions from both families of theories, we find that issues made by smaller and younger firms are more likely to involve stock-warrant units, and firms with greater stock price volatility are more likely to issue units in seasoned offerings. Moreover, firms with relatively high levels of long-term debt, and those whose issues are underwritten by less prestigious underwriters are more likely to employ stock-warrant unit financing. Consistent with information signaling, we find that firms with high managerial ownership are more likely to issue units. Firms that include warrants in their stock offerings are predicted to have experienced higher abnormal stock returns than if they had issued shares alone. Thus, consistent with both theoretical explanations, some firms can reduce capital costs by adding warrants to shares in seasoned offerings.

Project finance links financial structure to the operational characteristics of the project to optimize the allocations of various project risks. We develop a model in which concession grants and offtake agreements benefit both public and private sponsors in the presence of political risk. The public can use these contracts to incentivize the private sponsor to undertake an otherwise unacceptable project while benefiting from delegating the process of financing, building, and operating the project to the private sponsor. For the private sponsor, the government concession grant, while improving financial returns, entails political influence. We develop hypotheses connecting these contract choices to the public–private partnership governance structure of project finance and provide supporting evidence. Our findings suggest that a country's political and financial risks have significant impacts on the contract choice as well as the public–private governance structure in project finance. Projects in greater political risk countries tend to be structured with less government involvement in order to avoid political influence of the local government. Projects with the private finance initiative end up with more government involvement and control in order to protect the public interest.
