We extend Lazear's theory of skills variety and entrepreneurship in three directions. First, we provide a theoretical framework linking new business creation with an entrepreneur's skill variety. Second, in this model we allow for both generalists and specialists to possess skill variety. Third,...

We propose that the rate of creation and failure of start-up firms can be modelled as a search and matching process, following labor market matching models. Setting out an endogenous growth model with entrepreneurship we derive a Entrepreneurship Beveridge Curve, through which we illustrate that...

We refine modelling of the radical innovation decision in this paper by extending real option theory to include non-marginal stochastic jump processes. From the model analytics we determine that the average magnitude and frequency of non-marginal stochastic jump processes are the most important...

In "new" new international trade theory, whether firms export or not are determined by their productivity. These models assume that firms enter a market to find their productivity levels revealed to them as in a lottery. In this paper we propose an alternative way to model whether firms export...

Economists' two main theoretical approaches to understanding Artificial Intelligence (AI) impacts have been the task-approach to labor markets and endogenous growth theory. Therefore, the recent integration of the task-approach into an endogenous growth model by Acemoglu and Restrepo (AR) is a...
