We provide a history of past periods of rapid technological change starting from the Industrial Revolution continuing up to today. We find that it takes decades for technological breakthroughs to make a difference to the aggregate economy. The reason for this delay is that to realize the value of these breakthroughs requires complementary investments. Second, for good or for bad, government has played an important role in facilitating these transitions through both investments in physical infrastructure and legal reforms. We also emphasize that because technological breakthroughs are difficult to predict, the responses of governments are necessarily improvisational.

This paper synthesizes the evidence of a negative correlation between income inequality and environmental quality. It shows that inequality exerts adverse impact on environmental outcomes through several channels, including the household, community, national, and international channels. These channels however overlap with one another and can thus reinforce the impact of inequality. Other dimensions of inequality, in particular gender inequality, also impact environmental quality negatively. The concept of the Environmental Kuznets Curve (EKC) is not that helpful in explaining the negative correlation between inequality and environmental quality. The findings of the paper suggest that…
