The Demand for, and Consequences of, Formalization among Informal Firms in Sri Lanka
通过在斯里兰卡对非正规企业进行实地实验，研究发现提供注册信息和报销直接成本不增加注册率，但支付相当于中位企业利润半个月至两个月的现金奖励能促使约五分之一至一半的企业注册，土地所有权问题是主要障碍，正规化后企业利润均值上升但主要由少数快速增长企业驱动。
A field experiment in Sri Lanka provides informal firms incentives to formalize. Information about the registration process and reimbursement of direct costs does not increase registration. Payments equivalent to one-half to one month (alternatively, two months) of the median firm's profits leads to registration of around one-fifth (alternatively, one-half) of firms. Land ownership issues are the most common reason for not registering. Follow-up surveys 15 to 31 months later show higher mean profits, but largely in a few firms that grew rapidly. We find little evidence for other changes in behavior, but formalized firms express more trust in the state.
