Firm entry, competitive pressures and the US inflation dynamics

This paper studies the effect of competitive pressures on inflation dynamics. To this end it derives and estimates a New Keynesian Phillips curve in a model with endogenous firm entry. The number of active firms is inversely related to their market power. By taking into account the number of competitors, the pass-through of real marginal cost on inflation is separately identifiable from the effect of endogenous desired markup fluctuations. Estimates with US data suggest that the effect of real marginal cost on inflation is stronger than that found in the empirical test of the standard model. The estimated elasticity of the desired markup with respect to the number of firms implies that an increase of 10% in the number of active firms would lower annual inflation by 1.4% in the short run.inflation dynamics, markups, firm entry

Unconventional Monetary Policy in Theory and in Practice

In this paper, after discussing the theoretical underpinnings of unconventional monetary policy measures, we review the existing empirical evidence on their effectiveness, focusing on those adopted by the European Central Bank and by the Federal Reserve. These measures operate in two ways: through the signalling channel and through the portfolio-balance channel. In the former, the central bank can use communication to steer interest rates and to restore confidence in the financial markets; the latter hinges on the hypothesis of imperfect substitutability of assets and liabilities in the balance sheet of the private sector and postulates that the central bank’s asset purchases and liquidity provision lower financial yields and improve funding conditions. The review of the empirical literature suggests that the unconventional measures were effective and that their impact on the economy was sizeable. However, a very large degree of uncertainty surrounds the precise quantification of these effects.Central bank, unconventional monetary policy, financial crisis, signalling channel, portfolio balance channel

External trade and monetary policy in a currency area

For historical and geographical reasons, the member countries of the European Monetary Union (EMU) display different degrees of external trade openness. The paper lays out a model for a currency area composed of two regions. One region is more open to trade with a third country outside the area than the other. Using the utility-based loss function for the currency area, the optimal monetary policy is compared to the one for a homogeneous area. In the model with heterogeneity, the relative competitiveness across regions influences the extent to which shocks are transmitted to the area-wide inflation and output gap. Under a plausible calibration for the EMU, the optimal policy plan exhibits a stronger tendency towards currency area exchange rate stabilization than the one in the homogeneity case. Moreover, it is welfare-improving to forgo some area-wide inflation stabilization to dampen inflation differentials.Monetary union, optimal monetary policy, loss function

Le principali recessioni italiane: un confronto retrospettivo

Il lavoro propone un’analisi comparata dell’andamento dei principali aggregati macroeconomici, reali e creditizi, nonché delle reazioni della politica monetaria in occasione delle più gravi recessioni attraversate dall’economia italiana. L’indagine, di tipo descrittivo, si concentra soprattutto sugli ultimi quarant’anni, per i quali il quadro informativo disponibile è ampio e dettagliato. In particolare, si confronta l’evidenza relativa alla profonda recessione del 2008-09 con quelle registrate nel 1974-75 e nel 1992-93, in corrispondenza delle crisi petrolifera e valutaria. Per un numero ridotto di variabili si propone anche un raffronto con gli andamenti negli anni trenta.Fluttuazioni cicliche, recessioni, offerta di credito, politica monetaria

The main recessions in Italy: a retrospective comparison

This paper proposes a comparative analysis of the main macroeconomic aggregates (both real and credit aggregates), and the monetary policy response during the most severe recessions experienced by the Italian economy. This descriptive study focuses mainly on the last forty years, a period for which there is ample and detailed information available. In particular, the paper contrasts the data on the current deep recession with those in 1974-75 and 1992-93, at the times of the oil crisis and the currency crisis respectively. For a selected list of variables, a comparison is made with the dynamics of the recession of the 1930s.gcyclical fluctuations, recession, credit supply, monetary policy

Essays on Inflation Dynamics and Monetary Policy in Currency Areas

Esta tesis extiende el modelo estándar Neo Keynesiano con el propósito de contestar dos preguntas: ¿cómo debe ser diseñada la política monetaria en uniones monetarias heterogéneas? y ¿cuál es el efecto de presiones competitivas sobre la dinámica de la inflación? El primer capítulo analiza el diseño de política monetaria en uniones monetarias en las cuales los países miembros muestran diferentes grados de apertura externa. Esta heterogeneidad implica que el plan de la política óptimo muestra una inclinación muy fuerte por la estabilización del tipo de cambio, con el objetivo de disminuir los diferenciales de inflación. El segundo capítulo estudia el diseño de reglas de metas en una unión monetaria con choques idiosincráticos cost-push que tienen diferentes volatilidades. El tercer capítulo estima un curva de Phillips Neo Keynesiana derivada de un modelo con entrada endógena de firmas, en el cual el número de firmas activas está inversamente relacionado con el markup deseado. Se cuantifica el efecto de las fluctuaciones del markup deseado sobre los costes marginales reales.This thesis extends the basic New Keynesian (NK) model to answer two questions. How should monetary policy be designed in heterogeneous currency areas? What is the effect of competitive pressures on the inflation dynamics? The first chapter analyzes the monetary policy design in currency areas in which countries display different degrees of external openness. Such heterogeneity implies that the optimal policy plan exhibits a stronger motive for the currency area exchange rate stabilization in order to dampen inflation differentials. The second chapter studies the design of targeting rules in currency areas with country-specific cost-push shocks that have different volatilities. The third chapter estimates a NK Phillips curve derived from a model with endogenous firm entry in which the number of active firms is inversely related to their desired markup. It quantifies the effect of the desired markup fluctuations on the pass-through of real marginal cost.
