How should one evaluate investment projects whose CCAPM betas are uncertain? This question is particularly crucial for projects yielding long-lasting impacts on the economy, as is the case for example for many green investments. We define the notion of a certainty equivalent beta. We show that...

This paper introduces a simulation model extending the well known Capital Asset Pricing Model by Sharpe and Lintner. Investors are modeled as multi-period forward looking portfolio optimizers. However, the future is not known \emph{a priori}, but has to be modeled and estimated. We allow agents...

Ways of finding a maximum skewness portfolio, with given return, variance and kurtosis, are presented. The methods take advantage of the special shape of the efficient portfolios manifold. Simpler solutions are obtained if the higher moments tensor has some particular structures. The problem of...

Because of the uncertainty about how to model the growth process of our economy, there is still much confusion about which discount rates should be used to evaluate actions having long-lasting impacts, as in the contexts of climate change, social security reforms or large public infrastructures...

This paper explores how the introduction of Rational Inattention (RI) affects optimal consumption and portfolio rules and asset pricing in the consumption-based CAPM framework. I first solve an otherwise standard portfolio choice and asset pricing model with RI explicitly and show that RI can...

A healthy financial system encourages the efficient allocation of capital and risk. The collapse of the house price bubble led to the financial crisis that started in 2007. There is a large empirical literature concerning the relation between asset price bubbles and financial crises. I evaluate...
