We use the introduction of a financial transaction tax (FTT) in France in 2012 to test competing theories on the impact of FTTs. We find no support for the idea that an FTT improves market quality by affecting the composition of trading volume. Instead, our results are in line with the idea that a lower trading volume reduces liquidity, and thereby market quality. Consistent with theories of asset pricing under transaction costs, we document a shift in security holdings from short-term to long-term institutional investors. More generally, our findings confirm that moderate aggregate effects on market quality can mask large adjustments made by individual market participants

We study the capacity choice problem of a firm whose access to capital is hampered by financial frictions in the form of moral hazard. The firm must therefore optimize not only its capacity investment under demand uncertainty, but also its sourcing of funds. Ours is the first study of this problem to follow an optimal contracting approach, where feasible source of funds are derived endogenously from fundamentals and include standard financial claims (debt, equity, convertible debt, call and put warrants, etc.) and combinations thereof. We characterize the optimal capacity level. First, we find conditions under which a feasible financial contract exists that achieves first-best. When no such contract exists, we find that under optimal financing, the choice of capacity sometimes exceeds strictly the efficient level. This runs counter to the literature on financing capacity investment in funds and the intuition that by raising the cost of external capital and hence the unit capacity cost, financial market frictions lower the optimal capacity level. We trace the value of increasing capacity beyond the efficient level to a bonus effect and a demand differentiation effect. In contrast to most of the literature on financing capacity, our results are robust to a change of financial contract

We build a model of investment and financing decisions to study the choice between bonds and bank loans in a firm's marginal financing decision and its effects on corporate investment. We show that firms with more growth options, higher bargaining power in default, operating in more competitive product markets, and facing lower credit supply are more likely to issue bonds. We also demonstrate that, by changing the cost of financing, these characteristics affect the timing of investment. We test these predictions using a sample of U.S. firms and present new evidence that supports our theory

We find that health cost risk lowers optimal annuity demand at retirement. If medical expenses can be sizeable early in retirement, full annuitisation at retirement is no longer optimal because agents do not have enough time to build a liquid wealth buffer. Furthermore, large deviations from optimal annuitisation levels lead to small utility differences. Our results suggest that health cost risk can explain a large proportion of empirically observed annuity choices. Finally, allowing additional annuitisation after retirement results in welfare gains of at most 2.5% when facing health cost risk, and negligible gains without this risk

How Much Do Means Tested Benefits Reduce the Demand for Annuities?

We analyze the effect of means-tested benefits on annuitization decisions using an administrative dataset of pension wealth cash-out choices. Availability of means-tested payments creates an incentive to cash out pension wealth for low and middle income earners, instead of taking the annuity. Agents trade off the advantages from annuitization, receiving longevity risk insurance, to the disadvantages, giving up “free” wealth in the form of means-tested supplemental income. Our life-cycle model demonstrates that the availability of means-tested benefits substantially reduces the desire to annuitize especially for low and intermediate levels of pension wealth. In our empirical analysis we show that the model’s predicted fraction of retirees choosing the annuity is able to match the annuitization pattern of occupational pension wealth observed in Switzerland
