英文摘要:
During the Great Recession, Democrats in the United States argued that government spending could be utilized to \"grease the wheels\" of the economy in order to create wealth and to increase employment; Republicans, on the other hand, contended that government spending is wasteful and discouraged investment, thereby increasing unemployment. Today, in 2020, we find ourselves in the midst of another crisis where government spending and fiscal stimulus is again being considered as a solution. In the present paper, we address this question by formulating an optimal control problem generalizing the model of Radner & Shepp (1996). The model allows for the company to borrow continuously from the government. We prove that there exists an optimal strategy; rigorous verification proofs for its optimality are provided. We proceed to prove that government loans increase the expected net value of a company. We also examine the consequences of different profit-taking behaviors among firms who receive fiscal stimulus.

中文摘要:
在大衰退期间,美国的民主党人认为,政府开支可以用来“润滑”经济,以创造财富和增加就业;另一方面,共和党人则认为,政府支出是浪费,不鼓励投资,从而增加了失业率。如今,在2020年,我们发现自己正处于另一场危机之中,政府支出和财政刺激再次被视为解决方案。在本文中,我们通过对Radner&Shepp(1996)模型的推广,提出了一个最优控制问题来解决这个问题。该模式允许该公司不断向政府借款。我们证明了存在一个最优策略;为其最优性提供了严格的验证证明。我们继续证明政府贷款增加了公司的预期净值。我们还研究了接受财政刺激的企业之间不同的获利回吐行为的后果。
