Even before the Dutch government has been able to introduce its environmental tax,

Corona strikes. This leads to such a low demand for air travel that the government

Calculate by how much the inverse demand function should shift in

to make the Cournot duopoly loss-making for FlyMe. Does this mean

that YouFly is automatically loss-making? Explain your answers clearly.
