Consider the new Keynesian Phillips curve withindexation, under the assumptions of perfect foresightand β = 1, together with our usual aggregate demandequation, yt = mt - pt.(a) Express pt+1 in terms of its lagged valuesand mt.(b) Consider an anticipated, permanent, one-time increasein m: mt = 0for t < 0, mt = 1for t ≥ 0. Sketch how you would find the resultingpath of pt.
