In the context of the Covid-19 pandemic, we evaluate the effects of vaccines and virus variants on epidemiological and macroeconomic outcomes by means of Monte Carlo simulations of a macroeconomic-epidemiological agent-based model calibrated using data from the Lombardy region of Italy. From simulations we infer that vaccination plays the role of a mitigating factor, reducing the frequency and the amplitude of contagion waves and significantly improving macroeconomic performance with respect to a scenario without vaccination. The emergence of a variant, on the other hand, plays the role of an accelerating factor, leading to a deterioration of both epidemiological and macroeconomic outcomes and partly negating the beneficial impacts of the vaccine. A new and improved vaccine in turn can redress the situation. Vaccinations and variants, therefore, can be conceived of as drivers of an intertwined cycle impacting both epidemiological and macroeconomic developments.
期刊介绍:
The journal aims to provide an international forum for a new approach to economics. Following the tradition of Joseph A. Schumpeter, it is designed to focus on original research with an evolutionary conception of the economy. The journal will publish articles with a strong emphasis on dynamics, changing structures (including technologies, institutions, beliefs and behaviours) and disequilibrium processes with an evolutionary perspective (innovation, selection, imitation, etc.). It favours interdisciplinary analysis and is devoted to theoretical, methodological and applied work. Research areas include: industrial dynamics; multi-sectoral and cross-country studies of productivity; innovations and new technologies; dynamic competition and structural change in a national and international context; causes and effects of technological, political and social changes; cyclic processes in economic evolution; the role of governments in a dynamic world; modelling complex dynamic economic systems; application of concepts, such as self-organization, bifurcation, and chaos theory to economics; evolutionary games.
