We analyze the implications of the decline in labor’s share in national income for optimal Ramsey taxation. It is optimal to accompany the decline in labor share by raising capital taxes only if the labor share is falling because of a decline in competition or other mechanisms that raise the...

We study optimal long-run capital taxation in a closed economy with heterogeneity in agents' time-discount factors where borrowing is allowed but restricted by a collateral constraint. Financial frictions distort intertemporal optimization margins and the tax system serves a dual role: first, it...

We analyze optimal capital and labor taxes in a model where (i) the government makes noncontingent announcements about future policies and (ii) ex-post state-contingent deviations from these announcements are costly. With Full Commitment, optimal fiscal announcements are unbiased forecasts of...

We develop a macroeconomic framework in which firms are large and have market power with respect to both products and labor. Each firm maximizes a share-weighted average of shareholder utilities, which makes the equilibrium independent of price normalization. In a one-sector economy, if returns...

What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore crosscountry spillovers of tax...

Europe's debt crisis casts doubt on the effectiveness of fiscal austerity in highly-integrated economies. Closed-economy models overestimate its effectiveness, because they underestimate tax-base elasticities and ignore cross-country tax externalities. In contrast, we study tax responses to debt...

This paper analyzes the effects of time-consistent capital taxation on the level of capital and welfare. We find that a commitment to a zero capital tax shifts the time inconsistency problem towards labor taxes and the provision of public consumption. By comparing the worst time-consistent...
