We introduce a new jackknife variance estimator for panel-data regressions. Our variance estimator can be motivated as the conventional leave-one-out jackknife variance estimator on a transformed space of the regressors and residuals using orthonormal trigonometric basis functions. We prove the...

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....

The objective of this study is to analyse whether differences exist in the value relevance of intangible assets (IA) and intellectual capital (IC) between firms in the financial sector and other industries. A quantitative approach was adopted. Drawing on the work of Ohlson (1995), an original...

This article analyses how hiring older workers adjusts to demographic change in the labour force by using information from more than 500,000 firms in Germany. We find robust evidence that firms faced with an ageing labour market hire relatively more older workers. However, the pace of this...

This paper revisits the estimation of private returns to R&D. In an extension of the standard approach, we allow for endogeneity of production decisions, heterogeneity of R&D elasticities, and asymmetric treatment of intramural and extramural R&D. Our empirical analyses are based on an extended...

This study presents novel empirical evidence on the optimal disaggregated public debt-growth threshold in the WAMZ over the period 1996-2022. Determining the public debt-growth threshold in a disaggregated form is crucial for macroeconomic policy measures in the region to curb high public debt...
