We introduce a general framework for models of cascade and contagion processes on networks, to identify their commonalities and differences. In particular, models of social and financial cascades, as well as the fiber bundle model, the voter model, and models of epidemic spreading are recovered...

We demonstrate by mathematical analysis and systematic computer simulations that redistribution can lead to sustainable growth in a society. In accordance with economic models of risky human capital, we assume that dynamics of human capital is modeled as a multiplicative stochastic process...

We develop a tractable dynamic model of productivity growth and technology spillovers that is consistent with the emergence of real world empirical productivity distributions. Firms can improve productivity by engaging in in-house R&D, or alternatively, by trying to imitate other firms’...

A stabilization theorem for processes of opinion dynamics is presented. The theorem is applicable to a wide class of models of continuous opinion dynamics based on averaging (like the models of Hegselmann–Krause and Weisbuch–Deffuant). The analysis detects self-confidence as a driving force...

We demonstrate by mathematical analysis and systematic computer simulations that redistribution can lead to sustainable growth in a society. The human capital dynamics of each agent is described by a stochastic multiplicative process which, in the long run, leads to the destruction of individual...

Self-efficacy, which can be defined as optimism about one's own ability to exercise required actions, has received a lot of attention in research on entrepreneurs' and managers' decision making. This attention led to the development of corresponding measurement instruments. However, there is no...

We investigate the relationship between gender and foreign language anxiety (FLA) in the second language (L2: English) of 320 adult bilinguals (L1: Dutch) outside the foreign language learning context. Results show that females experience higher levels of FLA. The association between gender and...

For a sample of 1243 European companies, we analyse the link between firm type and foreign direct investment (FDI) locations. We find substantial empirical evidence that being a family firm does not only affect the overall propensity for FDI but that this effect is also specific to target...

In this article we theoretically develop and empirically test an integrative conceptual framework linking dispositional optimism as general outcome expectancy to general efficacy beliefs about internal (self) and external (instrumental social support and chance) factors as well as to general...
