We develop a novel machine learning method to estimate large dimensional time-varying GMM models via our newly designed ridge fusion regularization scheme. Our method is a one-step procedure and allows for abrupt, smooth and dual type time variation with a fast rate of convergence. It...

The popular conditional autoregressive Wishart (CAW) model for dynamics of realized covariance matrices provides a flexible parametrisation. However, the number of parameters grows quadratically with the number of assets, which causes enormous computational difficulties in higher dimensions....

Recessions and expansions are often caused or reinforced by developments in private consumption - the largest component of aggregate demand - which, as a result, varies over the business cycle. As such, an accurate measurement of the cyclical component of consumption and an understanding of its...

We extend the canonical income process with persistent and transitory risk to shock distributions with left …-skewness and excess kurtosis, to which we refer as higherorder risk. We estimate our extended income process by GMM for household … show that in a standard incomplete-markets life-cycle model, first, higher-order risk has sizable welfare implications …
