AN ESTIMATE OF THE AGE DISTRIBUTION'S EFFECT ON CARBON DIOXIDE EMISSIONS
利用46个国家1990-2006年的面板数据，通过工具变量法估计年龄分布对二氧化碳排放的影响，发现35-49岁人口比例增加会显著提高排放量。
We estimate the age distribution's impact on carbon dioxide emissions from 1990 to 2006 by exploiting demographic variation in a panel of 46 countries. To eliminate potential bias from endogeneity or omitted variables, we instrument for the age distribution in a country's current population with lagged birth rates, and the regressions control for total population, total output, and country and year fixed effects. Carbon dioxide emissions increase with the share of the population aged 35 to 49 years, and this result is statistically significant and quantitatively large .
