The empirical and theoretical evidence on the inflation impact of population aging is mixed, and there is no evidence regarding the volatility of inflation. Based on 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 is also the first to discuss, using this framework, how aging affects the short-term cyclical behavior of the economy and the transmission channels of monetary policy. Further, we are also the first to 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 with aging, our model suggests that aging makes monetary policy less effective, and aggregate demand less elastic to changes in the interest rate. Moreover, in more gray societies central banks should react more strongly to nominal variables, and in a very old society the nominal GDP targeting rule might become the most effective monetary policy rule to compensate for higher inflation volatility.

We extend OGRE, the overlapping generation model developed by Baksa and Munkacsi (2016) by adding openness. We then employ the model to explore how the macroeconomic effects of aging, assumed to manifest itself as a decrease in the mortality rate, can be counteracted through public policies. The extended version inherits the previous modelling features of OGRE allowing us to also account for the impact openness has on the effectiveness of the considered policies.

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.

In this paper we present the structure of OGRE, a dynamic general equilib-rium 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.
