Which inflation to target? A small open economy with sticky wages indexed to past inflation

In a closed economy context there is common agreement on price inflation stabilization being one of the objects of monetary policy. Moving to an open economy context gives rise to the coexistence of two measures of inflation: domestic inflation (DI) and consumer price inflation (CPI). Which one of the two measures should be the target variable? This is the question addressed in this paper. In particular, I use a small open economy model to show that once sticky wages indexed to past CPI inflation are introduced, a complete inward looking monetary policy is no more optimal. I first, derive a loss function from a second order approximation of the utility function and then, I compute the fully optimal monetary policy under commitment. Then, I use the optimal monetary policy as a benchmark to compare the performance of different monetary policy rules. The main result is that once a positive degree of indexation is introduced in the model the rule performing better (among the Taylor type rules considered) is the one targeting wage inflation and CPI inflation. Moreover this rule delivers results very close to the one obtained under the fully optimal monetary policy with commitment.Inflation, open economy, sticky wages, indexation

Oil price shocks: Demand vs Supply in a two-country model

From the last quarter of 2001 to the third quarter of 2005 the real price of oil increased by 103%. Such an increase is comparable to the one experienced during the oil shock of 1973. At the same time, the behaviour of real GDP growth, Consumer Price inflation (CPI inflation), GDP Deflator inflation, real wages and wage inflation in the U.S. in the 1970s was very different from the one exhibited in the 2000s. What can explain such a difference? Within a two-country framework where oil is used in production, two kinds of shocks are analyzed: (a) a reduction in oil supply, (b) a persistent increase in foreign productivity (as proxy for the experience of China in the last years). It is shown that, while the 1970s are consistent with a supply shock, the shock to foreign productivity generates dynamics close to the one observed in the 2000s.oil price, open economy, demand and supply shocks.

Labor Market Participation, Unemployment and Monetary Policy

In the present paper we examine how the introduction of endogenous participation in an otherwise standard DSGE model with matching frictions and nominal rigidities affects business cycle dynamics and monetary policy. The contribution of the paper is threefold: first, we show that the model provides a good fit for employment and unemployment volatility, as well as participation volatility and its correlation with output for US data. Second, we show that in such a model, and contrary to a model with exogenous participation, a monetary authority that becomes more aggressive in fighting inflation decreases the volatility of employment and unemployment. Finally, we show the role of search costs in shaping those results.matching frictions, endogenous participation, monetary policy

Fiscal Calculus in a New Keynesian Model with Labor Market Frictions

During the Great Recession following the recent financial crisis large fiscal stimuli were implemented to counteract labor market sclerosis. We explore the effectiveness of various fiscal packages in a matching model featuring inefficient unemployment and a rich fiscal sector employing distortionary taxation and government debt. Results show that only stimuli directed toward the labor market, such as hiring subsidies, deliver large multipliers. Those policies can, indeed, abate the congestion externality, pervasive in the labor market. Various robustness checks confirm the results. The results obtained in the calibrated model are also confirmed through Bayesian estimation.fiscal calculus, taxation, matching frictions, bayesian estimation

Trade Policy: Home Market Effect vs Terms of Trade Externality

We study trade policy in a two-sector Krugman type model of trade. We conduct a general analysis allowing for three different instruments: tariffs, export taxes and production subsidies. For each instrument we consider unilateral trade policy without retaliation. When carefully disentangling the different effects that determine policy makers' choices and modeling general equilibrium effects of taxes/tariffs, we find that production subsidies are always inefficiently low and driven by terms of trade effects. In the cases of tariffs and export taxes the home market effect prevails for some parameter combinations but mostly trade policy is determined by terms of trade effects and the desire to reduce distortions arising from monopolistic competition. Hence, our analysis sheds new light on trade policy in a model of intra-industry trade.Home Market Effect, Terms of Trade, Tariffs and Subsidies

Trade policy: home market effect versus terms of trade externality

We study trade policy in a two-sector Krugman-type trade model with home market effects. We conduct a general analysis allowing for three different instruments: tariffs, export taxes and production subsidies. For each instrument, we consider unilateral trade policy without retaliation. When carefully disentangling the different effects that determine policy makers’ choices and modeling general equilibrium effects of taxes/tariffs, we find – contrary to the results of previous studies – that production subsidies are always inefficiently low and driven by the incentives to improve the (welfare relevant) terms of trade. In the cases of tariffs and export taxes results depend crucially on whether the free trade allocation is efficient. When starting from an allocation that is distorted because of monopolistic competition, the home market effect (and in the case of export taxes also the desire to correct for the monopolistic inefficiency) induces policy makers to set a tariff (an export subsidy). However, when monopolistic distortions are corrected, terms of trade effects dominate the choice of trade policy and lead to an import subsidy (an export tax).home market effect, terms of trade, tariffs and subsidies

Production of Lipid Microparticles Magnetically Active by a Supercritical Fluid-Based Process

An original technique, based on supercriticalCO2and on the particles from gas saturated solution (PGSS) micronization method, was developed to obtain magnetically active lipid microparticles. Magnetite nanoparticles (MNPs) were encapsulated into triestearin and phosphatidylcholine mixtures to increase their biocompatibility for future applications in the fields of biomedical diagnostics and therapeutic medications. The lipid particles produced were characterized to determine size and size distribution, and to confirm the encapsulation of MNP. The mean size was in the range of 200–800 nm. The possibility to drive these magnetically active particles by an external magnet was demonstrated in a simple apparatus simulating a vessel of the circulatory system. The results obtained indicate that the modified PGSS technique is suitable to produce lipid microparticles with magnetic activity for possible use in medical applications
