(Provides original sociological research on the development of consumer credit scoring in the United States and its links to subprime mortgage finance.)

We study a benchmark model with collateral constraints and heterogeneous discounting. Contrarily to a rich literature on borrowing limits, we allow for rental markets. By incorporating this missing market, we show that impatient agents choose to rent rather than to own the collateral in the...

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...

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...
