Should public assets such as infrastructure, education, and the environment earn the same return as private investments? The long-term nature of public investments provides commitment to current preferences, which justifies lower than private returns for time-inconsistent decision markers. An...

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...

The objective of this paper is to critically assess the use of simple rules for the social cost of carbon (SCC) that employ a rudimentary form of the Ramsey Rule. Two interrelated caveats apply. First, if climate change poses a serious problem, it is hard to justify an exogenous constant growth...

We introduce a model of the banking sector that formally incorporate a buffer function of capital. Heterogeneous banks choose their portfolio risk, bank size, and capital holdings. Banks voluntarily hold equity when the buffer effect against the risk of default outweighs the cost advantages of...

In many countries environmental policies and regulations are implemented to improve environmental quality and thus individuals’ well-being. However, how do individuals value the environment? In this paper, we review the Life Satisfaction Approach (LSA) representing a new non-market valuation...

Weitzman (1998) showed that when future interest rates are uncertain, using the expected net present value implies a term structure of discount rates that is decreasing to the smallest possible interest rate. On the contrary, using the expected net future value criterion implies an increasing...

It is not immediately clear how to discount distant-future events, like climate change, when the distant-future discount rate itself is uncertain. The so-called Weitzman-Gollier puzzle is the fact that two seemingly symmetric and equally plausible ways of dealing with uncertain future discount...

The efficient rate of return of a zero-coupon bond with maturity t is determined by our expectations about the mean (+), variance (-) and skewness (+) of the growth of aggregate consumption between 0 and t. The shape of the yield curve is thus determined by how these moments vary with t. We...

The government's choices of the corporate tax rate and public investment are interdependent. In particular, they both respond positively to the other. Therefore, international tax competition not only drives corporate tax rates to lower levels but might also affect negatively the stock of public...
