This Paper reports a new test of capital structure theories. It uses a filtering technique to identify large investment spikes. We find that the spikes are predominantly financed with debt by large firms and by new equity by small loss-making firms. In the process, firms move significantly away...

This Paper re-examines the impact of capital income taxes on the incentive to invest in the presence of risk. Specifically, it challenges a well-known claim in the literature that such a tax can leave incentives ‘basically unaffected’ because the tax liability is offset by a reduction in the...

This paper proposes a methodology for computing effective average tax rates using national accounts and revenue statistics, and applies it to construct time-series of tax rates for the seven largest industrialized countries. The resulting tax rates are consistent with available estimates of...

This paper discusses a model corporate tax system based on the application of the residence principle. This tax system, while preserving national sovereignties, minimizes the distortions arising from international capital mobility. The paper is motivated by an analysis of European capital income...

We analyze optimal taxation in an economy with monopsonistic labour markets. The individuals, whose only decisions are whether to work, or not, have heterogeneous productivities and opportunity costs of work. Given its preferences for redistribution, the government, which does not observe the...

This Paper analyses the optimal timing of taxes on capital income. We show that the celebrated result that taxes should front-loaded with an initially high tax followed by a discrete jump to the steady state is knife-edge, hinging on capital having a constant depreciation rate. An empirically...

Economists traditionally tackle normative problems by computing optimal policy, ie the one that maximizes a social welfare function. In practice, however, a succession of marginal changes to a limited number of policy instruments are implemented, until no further improvement is feasible. I call...

This paper derives optimal inheritance tax formulas that (a) capture the key equity-efficiency trade-off, (b) are expressed in terms of estimable sucient statistics, (c) are robust to the underlying structure of preferences. We consider dynamic stochastic models with general and heterogeneous...
