报告摘要：We study a continuous-time green fiscal stimulus problem for a firm at different levels of green investment. The firm can access government loans up to a maximum limit and balance the trade-off between shareholders’ benefits and its environmental responsibility to optimize cash management and investment policies. This framework involves a challenging singular control problem of a two-dimensional degenerate diffusion system but enables a unified analysis of the marginal value of government spending and the impact of loan availability on both brown and green firms. We provide theoretical insights into the lower dividend payments and higher take-up of loans for greener firms relative to brown firms. The model predictions together with the numerical results have implications for how policymakers can prioritize green spending and plan green stimulus programmes.
