Die Fähigkeit zu erfolgreicher technologischer Innovation, in ihrer Bedeutung für wirtschaftliches Wachstum und unternehmerische Wettbewerbsfähigkeit unbestritten, ist im Verlauf zunehmender Intensivierung des Globalisierungsprozesses wieder zu einem hochaktuellen Thema in Wissenschaft,...

Numerous empirical studies have shown evidence of nonlinearities in financial time series, which can be of both a deterministic and a stochastic nature. Chaos is an example of the former, and heteroscedasticity in the conditional variance an example of the latter. We apply a test, the BDS test,...

Economists typically make simplifying assumptions to make the solution and estimation of their highly complex models feasible. These simplifications include approximating the true nonlinear dynamics of the model, disregarding aggregate uncertainty or assuming that all agents are identical. While...

Testing serial dependence is central to much of time series econometrics. A number of tests that have been developed and used to explore the dependence properties of various processes. This paper builds on recent work on nonparametric tests of independence. We consider a fact that characterises...

In this paper, I first show that Swedish job polarization is - contrary to common belief - a long-run phenomenon: the share of middle-wage jobs has declined relative to the highest- and lowest-paid jobs since at least the 1950s. Based on previous results for the US, I then demonstrate that the...

We use individual survey data providing detailed information on stress, technology adoption, and work, worker, and employer characteristics, in combination with recent measures of AI and robot exposure, to investigate how new technologies affect worker stress. We find a persistent negative...

We document a strong negative link between self-employment and the rate of digital adoption by firms in developing and emerging economies. No link between digital adoption and the unemployment rate is found, however. To explain this evidence, we build a general equilibrium search-and-matching...
