Dr Dennig is interested in policy questions relating to climate change and inequality. For example, it is possible that climate change as well as climate policy will affect poor people disproportionately. Climate policy might thereby have an important impact on inequality. With a group of co-authors, Dr Dennig has looked at how this and other factors, such as population growth and health co-benefits, are best taken into account in climate policy. Dr Dennig is also interested in understanding other determinants of economic inequality. With other colleagues, he is investigating how family planning might affect the distribution of capital and how the market in the supply of education might affect the distribution and the returns to human capital. The motivation is to tackle questions that might lead to useful policy implications on these important issues.
