Direct recognition statutes, such as freedom of choice and vendorship laws, have the potential to increase the number of independent providers of psychotherapy, and thus to increase competition in the market for psychotherapy. These laws increase the economic return to private practice by requiring that third-party payers directly reimburse psychologists and social workers. There has been, however, little empirical investigation of the responsiveness of psychotherapists' employment choices to changes in the economic return to private practice. In this study, a structural model of social workers' earnings and employment choices between private practice and salaried employment is estimated. After correcting for the potential self selection bias, the results suggest that increasing the relative return to private practice does not increase the probability that a social worker will enter private practice.
直接认可法规，如选择自由和供应商法律，有可能增加心理治疗独立提供者的数量，从而增加心理治疗市场的竞争。这些法律要求第三方付款人直接向心理学家和社会工作者报销费用，从而提高了私人执业的经济回报。然而，关于心理治疗师的就业选择对私人执业经济回报变化的反应，几乎没有实证研究。在本研究中，估计了社会工作者在私人执业和受薪就业之间的收入和就业选择的结构模型。在纠正了潜在的自我选择偏差后，结果表明，提高私人执业的相对回报并不会增加社会工作者进入私人执业的可能性。
