1、Market Timing and Capital Structure Motivation 1: The exist of “equity market timing”. Firms tend to issue equity when market value is high, relative to book value and past market values, and repurchase equity when market value is low. The findings are difficult to reconcile with the MMs capital str
2、ucture irreverent theory. In inefficient or segmented capital markets, market timing benefits ongoing shareholders at the expense of entering and exiting ones. Managers thus have incentives to time the market. 2 Motivation 2: Many corporate financing decisions depend on equity market timing. There i

The basic question is whether market timing
5、has a short-run or a long-run impact. One expects at least a mechanical, short-run impact. If firms subsequently rebalance away the influence of market timing financing decisions, then market timing would have no persistent impact on capital structure. The conclusion is that market timing has large,
6、 persistent effects on capital structure. 4 Purpose and conclusion 2: The results are explained with some theory of capital structure.

Allow us to study the evolution of capital structure. We exclude financial firms, firms with a minimum book valu

11、leverage decreases sharply following the IPO. Over the next 10 years, it rises slightly, while market value leverage rises more strongly; this is indeed an age effect, not a survival effect. The decrease in market leverage reflects the historically high market valuations prevailing at the end of the
12、 1990s. The concurrent increase in equity issues is suggestive of market timing. 8 Determinants of Annual Changes in Leverage Here we decompose the change in leverage to examine whether the effect comes through net equity issues, as market timing implies. We also use three other variables that Rajan
13、 and Zingales (1995) find to be correlated to leverage in several developed countries: asset tangibility, profitability, and firm size. 9 10 The results of panel A of table II are generally consistent with theoretical priors. Variables (lagged value) Expected sign Empirical sign M/B ratio - - PPE/A
14、ratio + + EBITDA/A ratio + or - - Log (S) + + f (D/A) When leverage is near one of these boundaries, the change in leverage can only go in one direction, regardless of the values of the other variables. 11 The change in leverage can be decomposed as follows: To regress each of these three components
15、 of changes in leverage on the market-to-book ratio and the other independent variables. 12 We further examine whether market-to-book affects leverage through net equity issues, as market timing implies. The clear result is that market-to-book affects leverage through net equity issues. 13 Two inter
16、esting patterns are worth noting: The effect of profitability on changes in leverage arises primarily because of retained earnings. Profitable firms issue less equity (+), but this effect is more than offset by higher retained earnings(-), so that the net effect of higher profits is to reduce leverage. Firm size plays an important
