As society braces for the potential havoc a changing climate could induce, it’s vital to gauge the range of shocks that the economy may soon endure. One way to quantify the effects of the potentially systemic shocks that could ripple through the financial system is to administer “stress tests”—a well-designed analytical process that has, for decades, been used by the IMF, World Bank and financial supervisors for detailed scenario planning to prevent future financial crises.

For years, economists have worked to develop a way of measuring general well-being and comparing it across countries. The main metric has been differences in income or gross domestic product per person. But economists have long known that GDP is an imperfect measure of well-being, counting just the value of goods and services bought and sold in markets.
The challenge is to account for non-market factors such as the value of leisure, health, and home production, such as cleaning, cooking and childcare, as well as the negative byproducts of economic activity, such as pollution and inequality. […]
In their blog, Ben Clements and Vitor Gaspar make the points that global energy subsidies are still very substantial, that there is a strong need for reform in many countries, and that now is a great time to do it. This blog sets out what we mean by “energy subsidies,” provides details on their estimation, and explains how they continue to be high despite the recent drop in international energy prices (Chart 1).
Our latest update of global energy subsidies shows that “pre-tax” subsidies—which occur when people and businesses pay less than it costs to supply the energy—are smaller than a few years back. But “post-tax” subsidies—which add to pre-tax subsidies an amount that reflects the environmental, health and other damage that energy use causes and the benefit from favorable VAT or sales tax treatment—remain extremely high, and indeed are now well above our previous estimates.
