The effects of oil shocks in inflation and growth have been widely discussed in the literature, however few have focused on the impact of oil price increases on unemployment. In order to shed some light on this problem, this paper develops a medium scale Dynamic Stochastic General Equilibrium model (dsge) that allows for oil utilization in production and consumption as in Acurio-Vasconez (2015); unemployment as in Mortensen & Pissarides (1994); and staggered nominal wage contracting as in Gertler & Trigari (2009). It then analyses the effects of oil price increases on the economy. The model recovers most of the well-known stylized facts observed after the oil shock in the 2000s’. A sensitivity analysis shows that the reduction of the bargaining power of households to negotiate wage contracts reduces the impact of an oil shock in unemployment, without affecting negatively gdp. However, it also shows that the reduction of bargaining power, together with wage flexibility strongly reduces the increase in unemployment after an oil shock, but causes a decrease in real wages, which reduces household income and affects GDP.
This paper analyses the drivers of French transport CO2 emissions over the period 1960-2017. A decomposition analysis is used to evaluate the relative contribution of five key drivers of passenger and freight transports emissions: transport demand, modal shift, vehicle load factor, energy efficiency and carbon intensity of the energy.
