In today's world of financial uncertainty, one major public concern is to assess (and possibly
improve) the stability of companies that take on risks. Actuaries have been aware of that …

Innovation-driven entrepreneurship has become a focus for economic development and
received increasing attention from policy makers and academics over the last decades …

In this paper we consider a modified version of the classical optimal dividend problem taking
into account both expected dividends and the time value of ruin. We assume that the risk …

In this paper we study the optimal dividend problem for a company whose surplus process
evolves as a spectrally positive Lévy process before dividends are deducted. This model …

In insurance mathematics, a compound Poisson model is often used to describe the
aggregate claims of the surplus process. In this paper, we consider the dual of the …

We revisit the dividend payment problem in the dual model of Avanzi et al.([2–4]). Using the
fluctuation theory of spectrally positive Lévy processes, we give a short exposition in which …

In this paper, we study the optimal control problem for a company whose surplus process
evolves as an upward jump diffusion with random return on investment. Three types of …

We consider the dual model, which is appropriate for modeling the surplus of companies
with deterministic expenses and stochastic gains, such as pharmaceutical, petroleum or …

In the dual model, the surplus of a company is a Lévy process with sample paths that are
skip-free downwards. In this paper, the aggregate gains process is the sum of a shifted …

The dual model with diffusion is appropriate for companies with continuous expenses that
are offset by stochastic and irregular gains. Examples include research-based or …
