We build a two-country open-economy monetary union DSGE model in order to explain some macroeconomic imbalances in the euro area. We fo cus on the role of cyclic al behaviour of public spending and sovereign risk premium. Pro-cyclical primary public expenditures in one country do not lead to...

This paper investigates the nature of the relationship between direct investment and country risk in southern countries, especially developing countries (vertical investment). Using a theoretical model, we show that a necessary condition exists and is sufficient for business risk to determine...

This article analyses the impact of oil price on bond risk premiums issued by emerging economies. No empirical study has yet focussed on the effects of the oil price on government bond risk premiums. We develop a model of credit spread with data from the EMBIG index of seventeen countries, from...

We provide a discipline for belief formation through a model of subjective beliefs, in which agents hold strategic beliefs. More precisely, we consider beliefs as a strategic variable that agents can choose (consciously or not) in order to maximize their utility at the equilibrium. These...

La Vallée (1968), in the expected utility model, gives a sufficient condition for positivity of the bid-selling spread. In this article, we show that this sufficient condition, namely decreasing absolute risk aversion (DARA) is in fact necessary. Moreover, we prove that the expected utility...

In this paper, a fully choice-based theory of disappointment is developed. It encompasses, as particular cases, EU theory, Gul's theory of disappointment (1991) and the models of Loomes and Sugden (1986). According to the new theory, the risk premium of a random prospect is the sum of two...

If an investor does care for utilities -and not for monetary outcomes- stochastic dominances should be expressed in terms of utility units ("utils"). If so, any "rational" investor may be characterized by an elementary utility function -called canonical utility function- which is such that the...

Although it is endowed with many interesting properties, the theory of decision-making under risk by Loomes and Sugden [1986] has never been given an axiomatics. In this paper, we make up for this omission because their lottery-dependent functional is endowed with many interesting properties to...

Why do investors keep different opinions even though they learn from their own failures and successes? Why do investors keep different opinions even though they observe each other and learn from their relative failures and successes? We analyze beliefs dynamics when beliefs result from a very...
