“…Italian estimates show that and that recovery takes about three weeks ( Remuzzi and Remuzzi, 2020 ), thus we set from which it follows that . The instantaneous rate of time preference is set at ( Barro and Sala-i Martin, 2004 ) and the tax rate at ( Di Nicola et al, 2017 ), the effectiveness of treatment measures is calibrated as in order to ensure that the optimization problem is well defined (i.e., the constraints and are met), the degree of health concerns and the effectiveness of social distancing have been normalized to unity, and for simplicity, while is varied between different levels to show the implications of different initial conditions on the optimal policy. As today, the number of COVID-19 cases at national level (about 300,000) is completely negligible (i.e., considering that Italy is populated by 60,461,826 people, it amounts to a share of infectives of 0.0049) thus we can apply our early epidemic stage model to characterize the national dynamics.…”
