摘要

Many studies use linear regressions of investment on Tobin's q to estimate normal investment levels, often concluding that financial reporting quality enhances investment efficiency. Our findings suggest these inferences are confounded by two key factors. First, consistent with asymmetric capital adjustment costs, investment is significantly less responsive to q values below one than to those above one. Second, firms with q values below one systematically exhibit lower financial reporting quality. By pooling q values above and below one, the standard linear investment-q model introduces substantial upward bias in prior estimates of the relation between reporting quality and investment efficiency. To address this issue, we propose a piecewise linear specification of the investment-q model that accounts for the distinct characteristics of observations when q is below one. This adjustment is crucial when the likelihood of q falling below one is systematically linked to the hypothesized determinants of investment efficiency.
