OGRE Model
with Zsuzsa Munkácsi

Working Paper 1: In this paper we present the structure of OGRE, a dynamic general equilibrium model with overlapping generations, unemployment and a shadow economy. Based on a parametrized version of the model, we examine the impacts of aging and calculate multipliers of public pension and other fiscal policies. Also, we contrast macroeconomic reactions with pay-as-you-go and fully funded pension plans. Lastly, we highlight the role of unemployment and that of the underground sector in the framework.

 

Working Paper 2: Southern Europe is currently experiencing a double-whammy: high levels of government debt coupled with a rapidly aging population. Thus, the consolidation of (pension) budgets seems inevitable. In this paper we examine the short- and long-run macroeconomic effects of public old-age pension reforms and other fiscal policies under conditions of population aging. To do so, we calibrate OGRE, a New Keynesian model with overlapping generations, unemployment and an underground sector to match annual data on Portugal and Spain. Our main finding is that a retirement-age increase is the least harmful policy with respect to long-run output. However, we raise some doubts about the feasibility of implementing this policy.

Convergence Stories of Post-Socialist Central-Eastern European Countries

with István Kónya

This paper views the growth and convergence process of five Central-Eastern Eu- ropean economies - the Czech Republic, Hungary, Poland, Slovenia and Slovakia - through the lens of an open economy, stochastic neoclassical growth model. We esti- mate for these countries a version of the model augmented by simple financial frictions. Our main question is whether shocks to the growth rate of productivity (“trend”), or shocks to the external interest premium are more important to understand the volatil- ity of GDP growth and its components. We find that while GDP growth fluctuations can be traced back to productivity shocks, the composition of GDP - and consumption in particular - was driven particularly by premium shocks. Investment-specific and labor-market shocks are also important. Our panel estimation allows us to separate global and local components for productivity-trend and interest-premium shocks. The results indicate that the global trend component is well approximated by the growth rate of the advanced European Union economies, and we also find tentative evidence that recent investment behavior is largely driven to a large extent by European Union funds. When looking at the global component of the implicit interest rate recovered from the estimation, we find that it tracks the observed real interest rate in the EU 15 countries until 2008, but sharply diverges thereafter. This final finding is consistent with the hypothesis that various capital market wedges and non-price restrictions to lending became important during and after the global financial crisis.

More Gray, More Volatile? 

Aging and (OptimaL) Monetary Policy

with Zsuzsa Munkácsi

The empirical and theoretical evidence on the impact of population aging on inflation is mixed, and there is no evidence regarding the volatility of inflation. Using advanced economies’ data and a DSGE-OLG model - a multi-period general equilibrium framework with overlapping generations - we find that aging leads to downward pressure on inflation and higher inflation volatility. Our paper shows how aging affects the short-term cyclical behavior of the economy and the transmission channels of monetary policy. We also examine the interplay between aging and optimal central bank policies. As aging redistributes wealth among generations, generations behave differently, and the labor force becomes more scarce. Our model suggests that aging makes monetary policy less effective, and aggregate demand less elastic to changes in the interest rate. Moreover, in grayer societies, central banks should react more strongly to nominal variables to compensate for higher inflation volatility.

Secular Stagnation and the Role of Expectations 

This paper reconsiders the secular stagnation hypothesis through the lens of bounded ratio- nality. The consequences of population aging on medium- and long-term equilibria are at the core of current macroeconomic discourse. According to the secular stagnation hypothesis, in aging societies, the GDP growth decelerates and the natural rate of interest decreases when households accumulate more savings for a longer lifespan. However, the negative relationship between the old-age dependency ratio and the real interest rate can be rejected or weakly explained by his- torical data from OECD countries. This paper presents a multi-period, Gertler-type OLG model that incorporates bounded rationality and empirically shows that a declining real interest rate is valid only for those countries where the agents’ behavior is consistent with the rational expectation equilibrium, or where the agents have a relatively long planning horizon.
