While there is nothing magical about geographic disparities, we find them to be a good way to illustrate how different pockets of the economy have performed over the recent expansion. By excluding the booming coastal cities from the rest of the US, it is easier to see just how large the “shortfalls” from maximum employment are in the bulk of the country.

Even before the COVID-19 crisis, it was clear that traditional economic measures had increasingly diverged from social outcomes. Despite a decade of economic expansion and falling unemployment, social conditions deteriorated across a variety of measures. COVID-19 has brought these pressures to a head. Looking ahead, social conditions will have rising impacts on markets as policy evolves to more explicitly consider such issues in evaluating its goals. Fiscal policy is likely to take on a greater role in the decade to come, and is inherently distributional. The Fed, too, is increasingly taking into account social disparities.

As macroeconomic investors, we focus on questions about the impact of climate change on the major economies around the world. There is considerable uncertainty regarding the physical impacts of climate change on economies; as we surveyed expert views on the topic, we found a wide range of plausible outcomes for investors to consider. While the physical impacts of climate change will take years to play out, the economic and market impacts of policy choices or other human responses to climate change are likely to take place much faster.

Policy makers have traditionally relied on broad, macroeconomic measures of how the economy is performing, such as GDP growth, the unemployment rate, and inflation. These measures are enshrined in most central bank mandates, for example. Over time, consistent economic growth with stable inflation led to rising prosperity, so these indicators were a pretty good proxy of what policy makers should pay attention to. But in recent years, social outcomes have increasingly diverged from traditional macroeconomic measures.
