We develop a climate-economy model with active learning. We consider three ways of active learning: improved observations, adding observations from the past and improved theory from climate research. From the model, we find that the decision maker invests a significant amount of money in climate...

I estimate the cost of meeting the EU 2030 targets for greenhouse gas emission reduction, using statistical emulators of ten alternative models. Assuming a first-best policy implementation, I find that total and marginal costs are modest. The statistical emulators allow me to compute the risk...

This paper reassesses the food consumption and dietary impact of the regimes of food and food price control and eventually, food rationing, that were introduced in Britain during the First World War. At the end of the War the Sumner Committee was convened to investigate the effects of these...

This article re-examines the food consumption of working class households in 1904 and compares the nutritional content of these diets with modern measures of adequacy. We find a fairly steep gradient of nutritional attainment relative to economic class, with high levels of vitamin and mineral...

The effect of learning on climate policy is not straightforward when climate policy is concerned. It depends not only on the ways that climate feedbacks, preferences, and economic impacts are considered, but also on the ways that uncertainty and learning are introduced. Deep (or fat-tailed)...

We re-assess the changes in British working class diets through WW1. The 1918 Sumner Committee’s work on this was limited by a lack of consistency across household surveys. Our rediscovered 1904 data allow a cleaner comparison. Though calorie intake was maintained, we find a closing of the...
