The article analyses Hawtrey's influence on Keynes's monetary thought. On the one hand Hawtrey carries on ricardian tradition and on the other he introduces the monetary macroeconomic paradigm. His theory includes both exogenous and endogenous money. Keynes is inspired by Hawtrey's approach but...

We show, by means of an example, that in models where default is subject to both collateral repossession and utility punishments, opportunities for doing Ponzi schemes are not always ruled out and (refined) equilibria may fail to exist. This is true even if default penalties are moderate as...

Páscoa and Seghir (2009) presented two examples to show that in the presence of utility penalties for default, collateral requirements do not always eliminate the occurrence of Ponzi schemes and equilibria may fail to exist. This paper aims at providing a counterexample to their claim. We show...

Testing for normality is of paramount importance in many areas of science since the Gaussian distribution is a key hypothesis in many models. As the use of semi–moments is increasing in physics, economics or finance, often to judge the distributional properties of a given sample, we propose a...

We consider a formal approach to comparative risk aversion and apply it to intertemporal choice models. This makes it possible to investigate whether standard classes of utility functions, such as those inspired from Kihlstrom and Mirman (1974), Selden (1978), Epstein and Zin (1989) or Quiggin...

We study the deterministic control problem of maximizing utility from consumption of an agent who seeks to optimally allocate his wealth between consumption and investment in a financial asset subject to taxes on benefits with first-in–first-out priority rule on sales. Short sales are...
