Scenarios for Future Global Growth to 2050

A CGD Working Paper with Zack Gehan. We develop scenarios for the shape of the global economy in 2050 building on a simple regression of the historic relationship between current income and lagged income, demographic features, climate, and education, using the coefficients to develop a “central” forecast and error terms to set high and low bounds on country outcomes. Scenarios examine combinations of low and high outcomes for different country groupings. “Central”  forecasts suggest slowing per capita growth rates for high income countries as well as many upper middle income countries including China, with continued global income convergence. Scenario exercises suggest the potential for considerable variation in outcomes including global share of the economy and voting power in international institutions..

The Ultimate Resource is Peaking

A CGD Working Paper. Julian Simon argued that more people were associated with more prosperity: human talents were the “ultimate resource” and the force behind rising living standards. The last 30 years have been consistent with that view. But, globally, we are making fewer workers—and, more importantly, fewer potential innovators. In rich countries, human capital is growing considerably more slowly than in the past. Meanwhile innovation per researcher appears to be dropping as the population of researchers ages, while it takes longer to get to the knowledge frontier and more collaboration to expand it. Combined with the fact we are increasingly intolerant of risk and increasingly desirous of innovations in sectors where it is particularly hard to increase productivity, it is little surprise that productivity growth is indeed declining. To extend our two-century era of comparatively rapid progress, we need radically reduced discrimination in the global opportunity to innovate.

Climate Change May Have Only Small Effects on Long-Run Global GDP. So What?

A CGD note. The long run global estimates of climate impact on GDP are small. That hides the fact that there are big volatility shocks and impacts are concentrated in poorer countries.  And that matters a lot for policy response.

A CGD note. Can't hurt asking....

The Simple Math of Development Finance

A CGD Note. In short: we want lots of investment in developing countries; it has to be financially sustainable; direct private project investment is very expensive, indirect private finance through multilateral development banks is a lot cheaper; so scaling through WB/AfDB/ADB/IADB is the sustainable (affordable) model.

America Shouldn’t Copy China’s Belt and Road Initiative

A co-authored Foreign Affairs piece with Scott Morris. The US should leave infrastructure to the World Bank and 'compete' bilaterally with China on human rather than physical capital.

Can Africa Help Europe Avoid Its Looming Aging Crisis?

A CGD working paper with George Yang.  There will be 95 million fewer working-age people in Europe in 2050 than in 2015, under business as usual. This will cause significant fiscal stress as well as slower economic growth. Potential responses include: (a) raising labor force participation by women and older workers; (b) automation; and (c) outsourcing. But none will be sufficient. This leaves immigration: while migrants create demand for jobs as well as fill them, they can help rebalance the ratio of working to non-working populations. The paper compares business as usual estimates of inflows to 2050 with the size of the labor gap in Europe. Under plausible estimates, business as usual will fill one-third of the labor gap. This suggests a need for an urgent shift if Europe is to avoid an aging crisis. Africa is the obvious source of immigrants, to mutual benefit.  Here's a short video presenting the paper.

Your World, Better

6046cfa1-d6ae-4d12-94ca-9a0ef7df86faYour World, Better: Global Progress and What You Can Do About It is a book written for the smart and engaged middle school student.  It looks at how America and the World has changed since the reader's parents and grandparents were young: what has happened to health and wealth, homes, school and work, rights and democracy, war and the environment, happiness and depression.   It talks about the things that have gotten better, the sometimes-intensifying challenges that remain, and what readers can do about them. 

Your World Better is optimistic, but it doesn’t shy away from the considerable problems we face: from inequality through discrimination and depression to climate change and infectious threats.  It is meant to encourage kids to help make the world better themselves: tip them from a sense of powerlessness toward action, not into complacency.

The pdf of Your World Better is available to download here for free.  Or you can buy a kindle version for 99 cents or a hard copy for $8.10 on Amazon (or six pounds on UK Amazon here).  Any author royalties from those sales will be donated to UNICEF (so far, a bit more than $800 has been donated, thanks!). I talk about the book to Marian Tupy for the Human Progress podcast and to two (fantastic) middle schoolers for NPR.  Then I did a Slack chat with five middle schoolers for Slate. A CGD discussion about the book and talking to children about progress is here. And here's a fifteen minute video about the book (or try it on Youtube).  I am happy for the *text* (not pictures) to be copied or redistributed in any medium, and/or remixed or transformed for any purpose, with attribution.

"Everyone, no matter how old, or how young, should read this. I’m sending to grandkids and their parents." --Nancy Birdsall

"Great read for middle school kids who want to understand how the world is getting better -- and can become even more so!" --Parag Khanna

"How can you pass up a free book?! And one that is so relevant for today? If you know a middle school student or teacher, pass this along! Incredibly fresh and honest." --Karen Schulte 

"Kids are taught that everything's getting worse and we're all doomed--factually incorrect, and a message that leads to cynicism & fatalism, not constructive action. An antidote: Charles Kenny's new Your World, Better..." --Steven Pinker
