Overconfidence behavior, one form of positive illusion, has drawn considerable attention throughout history because it is viewed as the main reason for many crises. Investors' overconfidence, which can be observed as overtrading following positive returns, may lead to inefficiencies in stock...

We propose two robust bootstrap-based simultaneous inference methods for time series models featuring time-varying coefficients and conduct an extensive simulation study to assess their performance. Our exploration covers a wide range of scenarios, encompassing serially correlated,...

We study a nonlinear relationship between corporate investment and Tobin’s q in the cross-section. After correcting for nonseparable measurement error in q with the aid of repeated measurement, we find evidence of heterogeneity in the investment-q relation. The investment-q sensitivity is...

This paper introduces non-linear dimension reduction in factor-augmented vector autoregressions to analyze the effects of different economic shocks. We argue that controlling for non-linearities between a large-dimensional dataset and the latent factors is particularly useful during turbulent...
