We use the concept of κ-ignorance to describe the output demand ambiguity. When a firm changes its level of capital, it incurs both fixed and proportional costs. Therefore, the firm\u0027s problem is formulated as a stochastic impulse control problem. We solve the firm\u0027s problem via quasi-variational inequalities and numerically derive an optimal capital expansion and reduction policy. Further, we numerically conduct a comparative statics analysis that confirms that output demand ambiguity promotes capital reduction, while delaying capital expansion. Additionally, combining both the effects shrinks the continuation region.", "subitem_description_type": "Abstract"}]}, "item_1_description_13": {"attribute_name": "内容記述", "attribute_value_mlt":
