Recent research has emphasized the impact of transaction costs on firm leverage adjustments. We recognize that cashflow realizations can provide opportunities to adjust leverage at relatively low marginal cost. We find that a firm's cashflow features affect not only the leverage target, but also the speed of adjustment toward that target. Heterogeneity in adjustment speeds is driven by an economically meaningful concept: adjustment costs. Accounting for this fact produces adjustment speeds that are significantly faster than previously estimated in the literature. We also analyze how both financial constraints and market timing variables affect adjustments toward a leverage target.

Christophe et al. (2010) find evidence of abnormal short activity prior to analyst downgrades and argue that short sellers may be violating SEC insider-trading laws by trading on information obtained from analysts about upcoming downgrades. However, observing abnormal shorting prior to downgrades is not tantamount to determining that short sellers are trading on tips from analysts unless shorting is abnormally low prior to upgrades. This paper revisits this issue. While we observe abnormal shorting prior to downgrades, we also find markedly higher shorting prior to upgrades. In fact, the short-selling patterns surrounding both downgrades and upgrades are remarkably symmetric indicating that short sellers during the pre-recommendation period are not unusually informed about the direction of upcoming recommendation changes. If anything, our findings indicate that short selling prior to analyst recommendations is more likely speculative than informed.

We quantify the importance of collateral versus taxes for firms' capital structures. We estimate a dynamic model in which a taxable firm seeks financing for investment, and a dynamic contracting environment motivates endogenous collateral constraints. Optimal leverage stays a safe distance from the constraint, balancing the tax benefit of debt with the cost of lost financial flexibility. We estimate this flexibility cost to be 7.2% of firm assets, a percentage that is comparable to the tax benefit. Models with different tax rates fit the data equally well, and leverage responds to the tax rate only when taxes are low.

We study fiscal behaviour and the sovereign yield curve in the US and Germany. We obtain the latent factors, level, slope and curvature, with the Kalman filter, and use them in a VAR with macro, fiscal and financial stress variables. In the US, fiscal shocks generate an immediate response of the short-end of the yield curve, associated with monetary policy, lasting 6–8 quarters, followed by a response of the whole yield curve lasting 3years, with an implied elasticity of long-term yields of 80% for the government debt shock and 48% for the budget balance shock. In Germany, fiscal shocks have entailed no significant reactions of the yield curve shape and no response of the monetary policy interest rate, notably after 1999; only in the case of debt shocks there is a short-lived decrease in the medium-end of the yield curve in the following 2nd and 3rd quarters.

In December 2003, the Brazilian Congress passed a law that led to a natural personal lending experiment. The law allows banks to offer loans with repayment through automatic payroll deduction, which, in effect, turns future income into collateral. We estimate the impact of the new law using auto loans as a control group. The law has caused a reduction in interest rates and an increase in the volume of personal credit.

The TRIPS Agreement, which specifies minimum levels of intellectual property protection for countries in the WTO, has increased levels of patent protection around the world. Using variation across countries in the timing of patent laws and the severity of disease, we test the hypothesis that increased patent protection results in greater drug development effort. We find that patent protection in wealthy countries is associated with increases in R&D effort. However, the introduction of patents in developing countries has not been followed by greater R&D investment in the diseases that are most prevalent there.

This paper explores the consequences of improving property rights to facilitate the use of fixed assets as collateral, popularly attributed to the influential policy advocate Hernando de Soto. We use an equilibrium model of a credit market with moral hazard to characterize the theoretical effects, and also develop a quantitative analysis using data from Sri Lanka. We show that the effects are likely to be non-linear and heterogeneous by wealth group. They also depend on the extent of competition between lenders. There can be significant increases in profits and reductions in interest rates when credit markets are competitive. However, since these are due to reductions in moral hazard, i.e. increased effort, the welfare gains tend to be modest when cost of effort is taken into account. Allowing for an extensive margin where borrowers gain access to the credit market, can make these effects larger depending on the underlying wealth distribution.

The surge in public debt triggered by the financial crisis has raised uncertainty about future tax pressure and economic activity. We examine the asset pricing effects of fiscal policies in a production-based general equilibrium model in which taxation affects corporate decisions by: (1) distorting profits and investment; (2) reducing the cost of debt through a tax shield; and (3) depressing productivity growth. In settings with recursive preferences, these three tax-based channels generate sizable risk premia, making tax uncertainty a first-order concern. We document further that corporate tax smoothing can substantially alter the effects of public expenditure shocks. The Author 2012.

Evidence evaluation in accounting often involves both the assessment of evidence relevance and the combination of its relevance and source to assess overall strength. We decompose this strength-assessment judgment into its components—relevance assessment and source and relevance combination—and consider the effects of experience. Participants in our experiment assess the strength and relevance of tax authorities in relation to a client scenario. Contrary to prior research, we find that more-experienced participants exhibit greater use of analogical reasoning when evaluating tax-authority relevance than do less-experienced participants. We find a similar experience effect in the use of configural information processing to combine authority source and relevance, a judgment not previously considered in tax. The effects of experience are particularly important in the current environment as the tax function is a leading cause of material weaknesses and restatements under Sarbanes-Oxley and tax executives cite increasing difficulty in hiring and retaining qualified professionals.
