We further provide evidence that the impact of technology adoption varies across diverse occupational and industrial contexts. Workers in occupations with a higher task substitution potential show stronger increases in overtime, training measures and labour intensity. Analysing industry characteristics, we find that employees exposed to a new technology react more strongly in industries with higher business dynamics in terms of organisational capital and R&D investment.

We demonstrate that the sign-based variants of the Phillips-Shi-Yu test retain their asymptotic validity in the presence of level shifts under a weak restriction on the number of shifts that occur. This is in contrast to the original Phillips-Shi-Yu test which only remains valid under a joint restriction involving both the number and magnitudes of the level shifts. We find, through Monte Carlo simulation, that the original test can display substantial over-size in the presence of level shifts, without a corresponding increase in power, while the sign-based variants are largely unaffected in both regards. The sign-based tests therefore offer robust and powerful methods for detecting an explosive autoregressive regime in a financial time series that potentially contains level shifts.

We then use household-level microdata to simulate the heterogeneous impact of monetary policy by income and wealth percentiles as well as demographic variables. Our results show that an expansionary monetary policy shock disproportionately benefits the young and households with medium to low income and wealth. These households tend to be highly leveraged homeowners who benefit disproportionately from higher house prices, lower interest costs on debt and a stronger labour market.

Step (ii) allows to model cross-sectional and time dependence left after the factors estimation. We prove the consistency of this approach as the time and cross-sectional dimensions diverge. In (ii), sparsity is allowed to be very general: approximate, row-wise, and growing with the sample size. However, the estimation error of (i) needs to be accounted for. Instead of simply plugging-in the standard rates derived for the PCA estimation of the factors in (i), we derive a refined expression of the error, which enables us to derive tighter rates for the lasso in (ii).
