The application and design of public-private partnerships between the extremes of purely public or purely private task fulfilment in public services is, in practice, subject to political processes. Decisions about PPPs (realisation, arrangement) are taken in the political arena and are therefore...

We introduce bureaucratic corruption in a simple way and examine its effect on government revenue when policies change. We show that a rise in the tax rate can lead to a fall in net revenue--a Laffer curve result due to the proportion of auditors that are corrupt and enforcement costs. It may...

This paper studies the design of optimal fiscal policy when a government that fully trusts the probability model of government expenditures faces a fearful public that forms pessimistic expectations. We identify two forces that shape our results. On the one hand, the government has an incentive...

In times when elevated government debt raises concerns about dimmer global growth prospects, we ask: How can the government provide incentives for innovation in a fiscally sustainable way? We address this question by examining the Ramsey problem of finding optimal tax and subsidy schemes in a...

We study optimal time-consistent distortionary taxation when the repayment of government debt is not enforceable. The government taxes labor income or issues noncontingent debt in order to finance an exogenous stream of stochastic government expenditures. The government can repudiate its debt...

For more than 25 years, the Social Security Trust Fund has been projected to run out of money in 2033 (give or take a few years), potentially causing benefits to be severely reduced in the absence of corrective legislative action. Today (February 2024), projections are made by the Social...

This paper analyzes optimal policy in setups where both the leader and the follower have doubts about the probability model of uncertainty. I illustrate the methodology in two environments: a) an industry populated with a large firm and many small firms in a competitive fringe, where both types...

We study the sustainability of public debt in a closed production economy where a benevolent government chooses scal policies, including haircuts on its outstanding debt, in a discretionary manner. Government bonds are held by domestic agents to smooth consumption over time and because they...

I study optimal capital and labor income taxation in a business cycle model with the recursive preferences of Epstein and Zin (1989) and Weil (1990). In contrast to the case of time-additive expected utility, I find that it is no longer optimal to make the welfare cost of distortionary taxes...

How should public debt be managed when uncertainty about the business cycle is widespread and debt levels are high, as in the aftermath of the last financial crisis? This paper analyzes optimal fiscal policy with ambiguity aversion and endogenous government spending. We show that, without...
