Abstract: Time preferences vary by age. Notably, according to experimental studies, senior citizens tend to discount future payoffs more heavily than working-age individuals. Based on these findings, we hypothesize that demographic change has contributed to the cut-back in government-financed investment that many advanced economies experienced over the last four decades. We demonstrate for a panel of 13 OECD countries between 1971 and 2007 that the share of elderly voters and public investment rates are cointegrated, indicating a long-run relationship between them. Estimating this cointegration relationship via pooled dynamic OLS (D-OLS) and fully modified OLS (FM-OLS) we find a negative and significant effect of population aging on public investment. Moreover, the estimation of an error correction model reveals long-run Granger causality running exclusively from aging to investment. Our results are robust to the inclusion of additional control variables typically considered in literature on the determinants of public investment.
