The most salient feature of financial dollarization, and the one that causes more concern to policy makers, is its persistence: even after successful macroeconomic stabilizations, dollarization ratios often remain high. In this paper we claim that this persistence is connected to the fact that...

In a fully micro-founded New Keynesian framework, we characterize analytically the relation between average inflation and oil price volatility by solving the rational expectations equilibrium of the model up to second order of accuracy. Higher oil price volatility induces higher levels of...

This paper evaluates the link between inflation and inflation uncertainty in a context of monetary policy regime shifts for the Peruvian economy. We use a model of unobserved components subject to regime shifts to evaluate this link. We verify that periods of high(low) inflation me an were...

The goal of this paper is to explain a recent regularity observed in economies in which central banks have moved from using a money aggregate as the instrument for the conduction of monetary policy towards a short-term interest rate (for example Peru in 2002). In particular, in those economies...

In this paper we analyse the effects of informal labour markets on the dynamics of inflation and on the transmission of aggregate demand and supply shocks. In doing so, we incorporate the informal sector in a modified New Keynesian model with labour market frictions as in the...

This paper provides a fully micro-founded New Keynesian framework to study the interaction between oil price volatility, pricing behavior of firms and monetary policy. We show that when oil has low substitutability, firms find it optimal to charge higher relative prices as a premium in...

This paper provides an overview of the reserve requirement measures undertaken by the Central Bank of Peru. It provides a rationale for the use of these instruments as well as empirical evidence of their effectiveness. In general, the results show that tightening reserve requirements has the...

In this paper we establish a link between the volatility of oil price shocks and a positive expected value of inflation in equilibrium (inflation premium). In doing so, we implement the perturbation method to solve up to second order a benchmark New Keynesian model with oil price shocks. In...
