At any other desired target for the inflation rate, there is an endogenous trade-off, even under the absence real imperfections such as sticky wages, and the divine coincidence no longer holds. The greater the degree of imperfect competition in the output market, the lower the real wage and hence the more the reduction falls on leisure (i.e. t [49][50] It combines the two equations of the new Keynesian Phillips curve and the Taylor rule with the dynamic IS curve derived from the optimal dynamic consumption equation (household's Euler equation). As economic agents can’t have a full scope of the economic reality, their information will be limited, and there will be little reason to believe that other agents will change their prices, and therefore keep their expectations unchanged. These early new Keynesian theories were based on the basic idea that, given fixed nominal wages, a monetary authority (central bank) can control the employment rate.
