Motivated by the complicated control issues of COVID-19, this article aims at investigating the optimal control of an epidemic of a Susceptible-Infective-Removed-Susceptible (SIRS) infection, where social distancing is the only control action in a first stage, whereas a combination of social...

According to the conventional theory of the demographic transition, mortality decline has represented the major trigger for fertility decline and eventually sustained economic development. In Sub-Saharan Africa (SSA), the HIV/AIDS epidemic has had a devastating impact on mortality, by...

A central policy issue in the battle against HIV in Sub-Saharan Africa (SSA) is whether and when high-prevalence countries might become fully autonomous in designing and implementing their own intervention policies aimed to control the disease. The aim of this research is twofold. First, it...

In a three-country model in which export countries adopt environmental policies, this note analyses how abatement ("green") subsidy can become a potential strategic trade policy tool. When governments set the optimal policy tool considering their local environmental damages, a rich set of...

It is commonly believed that the choice of adopting Corporate Social Responsibility (CSR) behaviours is beyond the scope of profit enhancement. In a unionised oligopoly with centralised wage setting and decreasing returns to scale technology, the present paper shows that the owners' choice of...

In a network industry, this paper investigates the impact of network effects on total pollution under the presence of a union interested to "local" environmental damages (e.g., polluting production processes damaging workers' health and the local environment where workers live). Under monopoly,...

The Corporate Social Responsibility (CSR) theory of the firm states that, in strategic markets, social actions lead to a prisoner's dilemma. This paper develops a model with pollution externalities and environmental taxation to incentivise firms' abatement activities through green R&D...

In a Cournot duopoly model in which exporters compete in a third market, this paper revisits the classical issue (dating back to the pioneering work of Brander and Spencer, Export Share and International Market Share Rivalry, 1985) of the strategic trade policy choice in the presence of the...

In a Cournot duopoly model in which exporters compete in a third market, this paper revisits the classical issue (dating back to the pioneering work of Brander and Spencer, Export Share and International Market Share Rivalry, 1985) of the strategic trade policy choice in the presence of the...

This research analyses the firms’ strategic choice of adopting an abatement technology in an environment with pollution externalities when the government levies an emission tax to incentivise firms undertaking emission-reducing actions. A set of different Nash equilibria – ranging from dirty...
