The impact of demographic changes on the real interest rate and international capital flows.

Abstract:

The demographic structure seems to change dramatically over the next 50 years in the Czech Republic. The aim of this study is to assess the impact of expected demographic changes on the future development of a real interest rate and international capital flows. In order to simulate the impact of the expected demographic changes upon the mentioned variables we apply a computable overlapping generations model. The real interest rate development is simulated under a closed economy assumption. As a result of the future expected demographic changes labour-capital ratio tends to fall, i.e. the real interest rate diminishes. The range of a change is significantly affected by a public budget closure rule. In case of an endogenous income tax rate, the real interest rate falls down by 0.5 percentage point. On the contrary, the real interest rate decreases by almost 1 percentage point in case when public transfers adjusted. Assuming an open economy, we simulate the impact of the expected demographic changes on the international capital flows between the domestic economy and the rest of the world. In case of increasing ratio of older agents, the aggregate domestic wealth surpasses the demand for capital by domestic firms. As a result a part of domestic capital is exported abroad. Increasing level of net foreign assets contributes to positive change in ratio of the balance of payment to the domestic production in a range from 2 to 5 percentage points over next 40 years if income taxes or public transfers change respectively.
