We document average abnormal stock returns of 14% for international insurance firms designated as Global Systemically Important Insurers (G-SII). These gains are associated with a fall in average default probability of 15.6%, and statistically weak and economically marginal increases in expected asset risk. Over the same event window, identical measures for other large insurance firms show no significant changes in equity returns or implied asset risk, but an increase in default probability of 27%. These results suggest that G-SII investors still perceive a net gain from TBTF protection, despite new compliance requirements and costs. Our evidence also suggests that these gains are driven primarily from reductions in default probability, as results are consistent with investor expectations that the new regulatory regime will limit moral hazard effects from the guaranty.

Why do corporations accumulate liquid assets? We show theoretically that intertemporal trade-offs between interest income taxation and the cost of external finance determine optimal savings. Intriguingly, we find that, controlling for Tobin's q, saving and cash flow are negatively related because firms lower cash reserves to invest after receiving positive cash-flow shocks, and vice versa. Consistent with theory, we estimate negative propensities to save out of cash flow. We also find that income uncertainty affects saving more than do external finance constraints. Therefore, contrary to previous evidence, saving propensities reflect too many forces to be used to measure external finance constraints.

This paper examines the degree to which cash flow availability influences firm investment in six OECD countries. In particular, we are interested in the extent to which the reliance on internal funds is affected by firm size, since there is general agreement that smaller firms have less access to external capital markets and, thus, should be more affected by the availability of internal funds. Earlier work has concluded that the documented positive relationship between cash flow and investment is evidence of the existence of financial constraints. We first examine all firms, regardless of size, in each country, and we find that the amount of corporate investment is affected by internal resources in all six countries; that is, internal financing affects firm investment. We then repeat the analysis segmenting the sample using three measures of firm size. Contrary to our a priori expectations, we find that the cash flow-investment sensitivity is generally highest in the large firm size group and smallest in the small firm size group. We deduce that the explanations for these findings are grounded in managerial agency considerations, and in the greater flexibility enjoyed by large firms in timing their investments. Thus, we conclude that the degree of sensitivity of a firm's investments to its cash flows cannot be interpreted as an accurate measure of its access to capital markets (as do Kaplan, S., Zingales, L., 1997. The Quarterly Journal of Economics 169–215), since small firms are known to have less access to external markets.
