GAP PROGRESSION

New life in the debates over poverty measurement

In recent weeks, a familiar debate over how we understand the global poverty rate across time reappeared in mainstream op-ed pages. Sparked initially by Bill Gates tweeting out an infographic produced by Our World in Data—which visualizes massive decreases (94% to 10% of people) in global poverty over the past two-hundred years—the notable discussants have been LSE anthropologist JASON HICKEL and Our World in Data researchers JOE HASELL and MAX ROSER.

Hickel published a polemical Guardian op-ed criticizing the publication of this chart, which, he argued, misrepresents the history it claims to communicate and relies on contestable and imprecise data sources to bolster its universal progress narrative, taking "the violence of colonisation and repackaging it as a happy story of progress." The responses were numerous.

Among them, a post by Hasell and Roser provided detailed descriptions of the methods and data behind their work to answer the following: "How do we do know that the vast majority of the world population lived in extreme poverty just two centuries ago as this chart indicates? And how do we know that this account of falling global extreme poverty is in fact true?"

In addition to methodological arguments regarding data sources and the poverty line, Hickel's argument emphasizes the gap between poverty and the capacity to eliminate it:

"What matters, rather, is the extent of global poverty vis-à-vis our capacity to end it. As I have pointed out before, our capacity to end poverty (e.g., the cost of ending poverty as a proportion of the income of the non-poor) has increased many times faster than the proportional poverty rate has decreased. By this metric we are doing worse than ever before. Indeed, our civilization is regressing. On our existing trajectory, according to research published in the World Economic Review, it will take more than 100 years to end poverty at $1.90/day, and over 200 years to end it at $7.4/day. Let that sink in. And to get there with the existing system—in other words, without a fairer distribution of income—we will have to grow the global economy to 175 times its present size. Even if such an outlandish feat were possible, it would drive climate change and ecological breakdown to the point of undermining any gains against poverty.

It doesn’t have to be this way, of course."

  • For a measured account, see this excellent post from Branko Milanovic. On Twitter, he summarizes Hickel: "1. Maddison's 19th century GDPs do not include the value of non-cash goods and services that was relatively high then [basically true]; 2. Bourguignon-Morrisson 19th century distributions are guesses [true]; 3. Poverty Line of $1.90 is unrealistically low (disputed); 4. How to account for the extreme costs of industrialization (coercion and the dead) [often ignored although life expectancy changes are used to adjust for it]." Link.
  • At Vox, Dylan Matthews provides a comprehensive summary of the recent debate's various back-and-forths, glossing the major disputes over the poverty line, historical data accuracy, and narrative. Link.
  • A 2018 paper by eminent poverty scholar Martin Ravallion takes stock of poverty debates with a focus on income inequality: "Given the scope for sensible people to disagree on the desirable properties of an inequality measure—and there is no scientific justification for the near monopoly of relative measures in applied work by economists—more productive debates on globalization and development might be possible if both sides better understood what concepts of inequality they are using. To talk about 'inequality' without making explicit whether one means absolute or relative inequality is especially problematic." Link.
  • These discussions over the nature of development, economic growth, and measures of economic progress derive from much earlier debates in international relations and development studies. In his canonical 1966 article, Andre Gunder Frank distinguishes between "undevelopment" and "underdevelopment," arguing that "underdevelopment is not due to the survival of archaic institutions and the existence of capital shortage in regions that have remained isolated from the stream of world history. On the contrary, underdevelopment was and still is generated by the very same historical process which also generated economic development." Link to the original text.

New Researchers: NO SUBSTITUTE

A paper finds no labor market losses resulting from minimum wage increases

In CARL NADLER'S job market paper—co-authored with SYLVIA ALLEGRETTO, ANNA GODOEY, and MICHAEL REICH—the authors build on literature that finds no job market losses resulting from minimum wage increases. The paper tests for labor-labor substitutions, a widely proposed hypothesis which suggests that employers' preferences shift in favor of skilled workers as the price of labor increases, thereby masking underlying job losses for low wage workers. It takes a concentrated look at the earnings and employment effects of increased minimum wage policies in Chicago, Washington DC, Oakland, San Francisco, San Jose, and Seattle. It also tests for labor-labor substitutions in California’s food industry.

The findings:

"In the six cities, we find positive earnings responses in the food services industry that are remarkably close to those estimated in recent studies of state and federal minimum wage increases. … Like these studies, we also do not detect any employment losses. … Our analysis of California food services finds no evidence of either labor-labor substitution or hours effects. As a result, the most likely explanation for our findings is that total labor demand elasticity for employment and hours combined is inelastic, and the policies have raised the earnings of low-wage workers in the six cities. ."
