In this paper, I search for an optimal configuration of parameters for variants of the Taylor rule by using an accurate second-order welfare-based method within a fully microfounded dynamic stochastic model, with price and wage rigidities, without capital accumulation. A version of the model...

We investigate how the relation between gold prices and the U.S. Dollar has been affected by the recent turmoil in financial markets. We use spot prices of gold and spot bilateral exchange rates against the Euro and the British Pound to study the pattern of volatility spillovers. We estimate the...

We study how immigration policies are determined under voting in a two-country model where immigration redistributes income from wages to capital. Migration decisions are endogenous, there exist border enforcement costs and preference for home-country consumption. We model the migration policy...

We consider the optimal trade execution strategies for a large portfolio of single stocks proposed by Almgren (2003). This framework accounts for a nonlinear impact of trades on average market prices. The execution strategy of Almgren (2003) is based on the assumption that no shares per unit of...

We study the role of nonlinear simple rules for monetary policy. We depart from the standard rules proposed by Taylor (1993), and consider a nonlinear rule for the so-called opportunistic approach to disinflation originally proposed by Orphanides and Wilcox (2002) and Aksoy, Orphanides, Small,...

This paper analyzes the specific role of fiscal policy on the welfare effects of macroeconomic stabilization policies. We extend current DSGE models à la Schmitt-Grohè and Uribe (2003) to a non-tandard fiscal policy framework. We focus on distortionary and progressive taxation which alters the...

The proponents of the 'opportunistic' approach to disinflation suggest that, when inflation is close to the target, the central bank should not counteract inflationary pressures. Orphanides and Wilcox (2002) formalize this idea through a simple policy rule that prescribes a nonlinear adjustment...
