[fre] Volatilité conditionnelle, signaux d'échange et perception du risque par Giampiero M. Gallo et Barbara Pacini . Cet article étudie le rôle d'un terme de volatilité conditionnelle exprimant la présence de risque dans la relation entre le taux de change courant et à terme sur données...

The effects of a job training program, Job Corps, on both employment and wages are evaluated using data from a randomized study. Principal stratification is used to address, simultaneously, the complications of noncompliance, wages that are only partially defined because of nonemployment, and...

Two approaches for dealing with "endogenous selection" problems when estimating causal effects are considered. They are principal stratification and selection models. The main goal is to highlight similarities and differences between the two approaches, by investigating the different nature of...

In this paper, we examine the characteristics of market opening news and its impact on the estimated coefficients of the conditional volatility models of the GARCH class. We find that the differences between the opening price of one day and the closing price of the day before have different...

In this paper we analyse the consequences of considering risk-augmented specifications of the relationship between spot and forward rates. Previous parametric specifications such as the GARCH-M provided disappointing results possibly due to the high degree of persistence of the estimated process...

We develop new methods for analyzing randomized experiments with noncompliance and, by extension, instrumental variable settings, when the often controversial, but key, exclusion restriction assumption is violated. We show how existing large-sample bounds on intention-to-treat effects for the...

The paper re-examines the question of excessive implied persistence of volatility estimates when GARCH type models are used. Ten actively traded US stocks are considered and as already established in the literature, when volume traded is inserted in the GARCH (1, 1) or (EGARCH 1, 1) models for...
