Protection for sale under monopolistic competition: Beyond the CES
No full textWe extend the protection for sale model of Grossman and Heiman (1994) by introducing a general model of monopolistic competition with variable markups and incomplete pass-through. We show that the structure of protection emerging in the political equilibrium not only depends on the weight attached by the government to consumer welfare when making its policy decision, but also on the degree of market power of firms and on the terms-of-trade variations due to the degree of pass-through. Our results highlight the importance of preferences in shaping the structure of protection and are consistent with the occurring of protectionism also in unorganized industries
Monetary Policy in a New Keynesian Model with Endogenous Growth
Full text linkWe study monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find the following results: (i) technology and government spending shocks have different effects on growth; (ii) disinflationary monetary policies entail positive effects on growth; (iii) the optimal long-run inflation rate is zero; (iv) the Ramsey dynamics implies deviation from full inflation targeting in response to technology and government spending shocks; (v) the optimal operational rule is backward looking and responds to inflation and output deviations from their long-run levels

INNOVATION, GROWTH, and OPTIMAL MONETARY POLICY
No full textThis paper examines how innovation-led growth affects optimal monetary policy. We consider the Ramsey policy in a New Keynesian model where R&D leads to an expanding variety of intermediate goods and compare the results with those obtained when the expansion occurs exogenously. Positive trend inflation is found to be optimal under both assumptions, but much higher with profit-seeking innovation. Optimal monetary policy must be counter-cyclical in response to both technology and public spending shocks, yet the intensity of the reaction crucially depends on the presence of an R&D sector. However, the small amount of short-run deviations of prices from the non-zero trend inflation observed in response to shocks suggests inflation targeting as a robust policy recommendation
Fiscal policy and exchange rates
No full textThis paper examines the dynamics of the nominal exchange rate and fiscal deficits in a continuous time optimizing general equilibrium model with OLG. It is shown that alternative financing modes of budget deficits imply different patterns of adjustment along the transitional path towards the steady-state equilibrium. In particular, the respect of public solvency without money financing is not sufficient to avoid the depreciation of the exchange rate in the long-run after a fiscal expansion. In addition, money and tax financing generate opposite intergenerational reallocation of wealth
Budget Deficits and Exchange-Rate Crises
No full textThis paper investigates currency crises in an optimizing general equilibrium model with overlapping generations. It is shown that a rise in government budget deficits financed by future taxes generates a decumulation of external assets, leading up to a speculative attack and forcing the monetary authorities to abandon the peg.
