Many different approaches have developed for the evaluation of non-tariff measures (NTMs) and free trade agreements (FTAs). Moving on from models using simple dummy variables, today a range of databases can capture different aspects of NTMs and FTAs. Some assess the depth of FTAs by extracting...

We propose an extended time-varying parameter Vector Autoregression that allows for an evolving relationship between the variances of the shocks. Using this model, we show that the relationship between the conditional variance of GDP growth and the long-term interest rate has become weaker over...

We develop non-parametric instrumental variable estimation and inferential theory for econometric models with possibly endogenous regressors whose coefficients can vary over time either deterministically or stochastically, and the time-varying and uniform versions of the standard Hausman...
