A generalization of the endogenous threshold model is developed by extending this class to a multivariate framework and to cases where the feedback acts at multiple lags. The feedback is specified, following Beaudry and Koop, by a variable which measures the depth of recessions. We give...

This paper analyses the business cycle properties of 183 time series relevant to the Italian economy, including real, monetary and international variables. We propose new monthly coincident and leading composite indicators for the Italian business cycle; the leading indicator anticipates the...

A generalization of the endogenous threshold model is developed by extending this class to multivariate framework and to cases where the feedback acts at multiple lags. The feedback is specified, following Beaudry and Koop, by a variable which measures the depth of recessions. We give conditions...

Unit roots in output, an exponential 2 per cent rate of convergence and no change in the underlying dynamics of output seem to be three stylized facts that cannot go together. This paper extends the Solow-Swan growth model allowing for cross-sectional heterogeneity. In this framework, aggregate...

The jump-diffusion model introduced by Merton is used to price a cross- section of options at different dates. At any point in time, the parameters of the model are estimated by minimizing the sum of squared implied volatility errors, and their informational content is compared with the widely...
