Do Measures of Financial Constraints Measure Financial Constraints?
提出两个检验方法，评估常用融资约束指标的有效性，发现被归类为受约束的企业实际上并未表现出受约束行为，现有发现可能反映企业生命周期阶段的差异。
Financial constraints are fundamental to empirical research in finance and economics. We propose two tests to evaluate how well measures of financial constraints actually capture constraints. We find that firms typically classified as constrained do not actually behave as if they were constrained: they have no trouble raising debt when their demand for debt increases exogenously and use the proceeds of equity issues to increase payouts to shareholders. Our evidence suggests that extant findings that have been attributed to constraints may instead reflect differences in the growth and financing policies of firms at different stages of their life cycles.
