Investment opportunities and corporate demand for lines of credit
建立了一个新模型，研究风险中性企业如何选择信用额度，以应对随机出现的短期投资机会，并平衡前期承诺成本与后续借款成本。
The behavior of a risk neutral corporation in selection of a line of credit is modeled in a new framework where demand for credit lines by a firm arises from the stochastic arrival in continuous time of short-lived opportunities to capture investment projects. The firm needs speed and secrecy to capture projects before competitors. The firm chooses a credit line that balances its up-front commitment cost against the expected extra cost of borrowing in the spot market upon exhaustion of its credit line. The firm's demanded credit line depends upon both relative pricing within the contract and the nature of the firm's growth opportunities. Interestingly, while credit line demand is positively related to business growth prospects, it is potentially negatively related to uncertainty in those prospects.
