When deciding on the social desirability of public investment, the cost of a project is sometimes adjusted by a factor known as the Marginal Cost of Public Funds (MCPF) which captures the cost of raising public funds through distortionary taxation. However, there is no scholarly consensus on...

Financing productive public capital through distortionary taxes typically creates a trade-off: the optimal investment is determined as a compromise between efficiency-enhancing public investment and perturbing market efficiency, but is never socially optimal. In contrast, such a trade-off can...

It is well recognised that the issue of the social rate of discount applies only to the gains from public investment that accrues to the public sector. When it comes to measurement, however, there is a problem: public investment in infrastructure and the like do not usually yield direct...

This paper examines the macroeconomic returns on public and private investments in 18 advanced economies from 1965 to 2019, using a Vector Autoregressive (VAR) approach. We assess whether higher investment levels drive economic growth and explore the interplay between public and private...

The zero lower bound era introduced a new perspective on the functionality of fiscal rules. With such low interest rates, the argument goes, extending debt financed public investment spending would be reasonable and thus existing fiscal rules too restrictive. Using data of Swiss cantonal public...

We study the impacts of public investment, notably in construction and in R&D on economic growth and of crowding-out effects on private investment. For this purpose, we use Panel Vector Autoregression (PVAR) models and the Generalised Method of Moments (GMM) approach for 40 advanced and emerging...

We assess the relevance of macro rates of return on time-varying fiscal and external sustainability. First, we compute the total public and private macroeconomic rates of return for 16 OECD countries from 1980 to 2022. We find that there is a positive impact of higher investment returns on...

The appraisal of public investments is subject to formal guidelines which often require input prices, such as forecasted energy prices. Using Danish guidelines as a case study, we explore the discounting assumptions in these input prices and find rates ranging from 2.97% to 17.5%, markedly...

This paper investigates the impact of elections on the level and composition of fiscal instruments using a sample of 19 high-income OECD countries that can be characterized as developed, established democracies during the period 1972-1999. We find that elections shift public spending towards...

A growing literature suggests that office motivated politicians manipulate fiscal policy instruments in order to seek their re-election. This paper investigates the impact of electoral manipulation of the level and composition of fiscal policy on incumbent’s re-election prospects. This impact...
