We consider estimation and inference for a regression coefficient in panels with interactive fixed effects (i.e., with a factor structure). We demonstrate that existing estimators and confidence intervals (CIs) can be heavily biased and size-distorted when some of the factors are weak. We...

Linear panel models and the "event-study plots" that often accompany them are popular tools for learning about policy effects. In this paper, we introduce the "xtevent" package for Stata, which enables the construction of event-study plots following the suggestions in Freyaldenhoven et al....

We contribute to the literature on saving in retirement by studying the saving behavior of retirees in Iceland, a country where health care and nursing homes ares free of charge. This removes some of the precautionary motive for saving, leaving the bequest motive and other inter-generational...

We consider estimation and inference for a regression coefficient in panels with interactive fixed effects (i.e., with a factor structure). We show that previously developed estimators and confidence intervals (CIs) might be heavily biased and size-distorted when some of the factors are weak. We...

We examine the determinants of spreads based on views regarding sovereign riskiness. The empirical analysis relies on panel data estimation techniques for 30 sovereign bonds for the period of 2009Q1 to 2017Q1, with data in quarterly frequency. We find that indeed there is a wide asymmetry in the...
