This study develops a new monthly euro Area‐wide Leading Indicator (ALI) for the euro area business cycle. It derives the composite ALI by applying a deviation cycle methodology with a one‐sided band pass filter and choosing nine leading series. Our main findings are that i) the applied...

Das ifo Institut begleitet seit seiner Gründung im Jahr 1949 das aktuelle Wirtschaftsgeschehen durch seine regelmäßigen Konjunkturumfragen und Konjunkturprognosen. Im Jahr 2007 hat das ifo Institut zur methodischen Basis seiner Konjunkturforschung einen ersten Sammelband mit ausgewählten...

Consider an observed binary regressor D and an unobserved binary variable D*, both of which affect some other variable Y. This paper considers nonparametric identification and estimation of the effect of D on Y , conditioning on D* = 0. For example, suppose Y is a person's wage, the unobserved D...

This paper considers nonparametric identification and estimation of the regression function when a covariate is mismeasured. The measurement error need not be classical. Employing the small measurement error approximation, we establish nonparametric identification under weak and...

This paper proposes a powerful alternative to the t-test of the null hypothesis that a coefficient in linear regression is equal to zero when a regressor is mismeasured. We assume there are two contaminated measurements of the regressor of interest. We allow the two measurement errors to be...
