Dollarization as a Signaling Device

The objective of this paper is to point out that dollarization, apart from being a commitment device, may also be used as a signaling device if there is uncertainty about the government’s intentions. To this end, we modify the standard approach to modeling monetary policy by introducing two types of government: good and bad. It is assumed that the good government conducts optimal policy while the bad government prefers to finance higher (than optimal) government expenditure by printing money. People do not observe the type of government, however they know the probability distribution over the two government types. Due to this uncertainty, the good government cannot achieve the first best even if it conducts optimal monetary policy. Hence, the good government has an incentive to dollarize, while the bad governments avoids this step. As a result, we obtain a separating equilibrium where dollarization is a perfect signal of the government type.dollarization, monetary policy

The Macroeconomic Effects of Losing Autonomous Monetary Policy after the Euro Adoption in Poland

There are many issues associated with the Eurozone accession of Poland. The goal of this paper is to analyse one, but very important aspect, namely - the macroeconomic impact of the loss of autonomous monetary policy. In order to answer this question, we build a two country DSGE model with sticky prices. We begin by evaluating the performance of our model. Next, we investigate how joining the Eurozone will affect the business cycle behaviour of the main macroeconomic variables in Poland. We find that the Euro adoption will have a noticeable impact on the Polish economic fluctuations. In particular, the volatility of domestic output increases and the volatility of inflation decreases. Also, in order to quantify the effect of the Euro adoption, we compute the welfare effect of this monetary policy change. Our findings suggest that the welfare cost is not large.Monetary policy, EMU accession countries, Euro

Credit Crunch in a Small Open Economy

We construct an open-economy DSGE model with a banking sector to analyse the impact of the recent credit crunch on a small open economy. In our model the banking sector operates under monopolistic competition, collects deposits and grants collateralized loans. Collateral effects amplify monetary policy actions, interest rate stickiness dampens the transmission of interest rates, and financial shocks generate non-negligible real and nominal effects. As an application we estimate the model for Poland - a typical small open economy. According to the results, financial shocks had a substantial, though not overwhelming, impact on the Polish economy during the 2008/09 crisis, lowering GDP by a little over one percent.credit crunch, monetary policy, DSGE with banking sector

Reforming retirement age in DB and DC pension systems in an aging OLG economy with heterogenous agents

We analyze the effects of increasing the retirement age in two economies with overlapping generations and within cohort ex ante heterogeneity. The first economy has a defined benefit system, and the second economy is in transition from a defined benefit to a defined contribution. We find that if increase in the retirement age is phased in a way that allows agents to adjust, welfare is not reduced and welfare effects have a similar magnitude and between-cohort distribution in both types of the pension systems

Monetary and macroprudential policy with foreign currency loans

In a number of countries a substantial proportion of mortgage loans is denominated in foreign currency. In this paper we demonstrate how their presence affects economic policy and agents' welfare. To this end we construct a small open economy model with housing loans denominated in domestic or foreign currency. The model is calibrated for Poland - a typical small open economy with a large share of foreign currency loans (FCL). We show that FCLs negatively affect the transmission of monetary policy. In contrast, their impact on the effectiveness of macroprudential policy is much weaker but positive. We also demonstrate that FCLs increase welfare when domestic interest rate shocks prevail and decrease it when risk premium (exchange rate) shocks dominate. Under a realistic calibration of the stochastic environment FCLs are welfare reducing. Finally, we show that regulatory policies that correct the share of FCLs may cause a short term slowdown

Monetary policy in a non-representative agent economy: A survey

It is well-known that central bank policies affect not only macroeconomic aggregates, but also their distribution across economic agents. Similarly, a number of papers demonstrated that heterogeneity of agents may matter for the transmission of monetary policy on macro variables. Despite this, the mainstream monetary economics literature has so far been dominated by dynamic stochastic general equilibrium (DSGE) models with representative agents. This article aims to tilt this imbalance towards heterogeneous agents setups by surveying the main positive and normative findings of this line of the literature, and suggesting areas in which these models could be implemented. In particular, we review studies that analyze the heterogeneity of (i) households’ income, (ii) households’ preferences, (iii) consumers’ age, (iv) expectations, and (v) firms’ productivity and financial position. We highlight the results on issues that, by construction, cannot be investigated in a representative agent framework and discuss important papers modifying the findings from the representative agent literature.Heterogeneous Agents; Monetary Policy

Preference for Redistribution during Structural Change with Labor Mobility Frictions

Thorough structural change occurs periodically across world economies. In a parsimonious overlapping generation setup with political economy, we present a novel result: structural change not only exacerbates the rise in inequality but also strengthens the preference for redistribution. Labor mobility frictions are instrumental in this mechanism

On Welfare Effects of Increasing Retirement Age

We develop an OLG model with realistic assumptions about longevity to analyze the welfare effects of raising the retirement age. We look at a scenario where an economy has a pay-as-you-go defined benefit scheme and compare it to a scenario with defined contribution schemes (funded or notional). We show that, initially, in both types of pension system schemes the majority of welfare effects comes from adjustments in taxes and/or prices. After the transition period, welfare effects are predominantly generated by the preference for smoothing inherent in many widely used models. We also show that although incentives differ between defined benefit and defined contribution systems, the welfare effects are of comparable magnitude under both schemes. We provide an explanation for this counter-intuitive result
