The Unassuming Economist

From a new IMF working paper:

“Data show that middle-income households have continued to move down, and less so up, the income distribution in the United States since the 1970s—a phenomenon that is often referred to as the polarization or “hollowing out” of the income distribution. While the level of income polarization is generally lower in the richer states (defined as those with higher median household income levels), there have been wide variations in income polarization over time and across states. We develop two indices to measure income polarization, including a novel hollowing-out index. We also examine the proximate causes of income polarization, using an econometric analysis at both state and household levels. The results suggest that technology, measured by job routinization, and international trade, measured by job offshoring, can explain more than half of the rise in income polarization, with broadly equal contributions. Household characteristics, particularly better education, have had important countervailing effects on income polarization. Policies should continue promoting technological progress and international trade, but also recognize that these positive forces have important side-effects on the income distribution and household welfare that need to be understood and mitigated.”

Dani Rodrik says:

“That neoliberalism is a slippery, shifting concept, with no explicit lobby of defenders, does not mean that it is irrelevant or unreal. Who can deny that the world has experienced a decisive shift toward markets from the 1980s on? Or that center-left politicians—Democrats in the United States, Socialists and Social Democrats in Europe—enthusiastically adopted some of the central creeds of Thatcherism and Reaganism, such as deregulation, privatization, financial liberalization, and individual enterprise? Much of our contemporary policy discussion remains infused with norms and principles supposedly grounded in homo economicus.

But the looseness of the term neoliberalism also means that criticism of it often misses the mark. There is nothing wrong with markets, private entrepreneurship, or incentives—when deployed appropriately. Their creative use lies behind the most significant economic achievements of our time. As we heap scorn on neoliberalism, we risk throwing out some of neoliberalism’s useful ideas.

The real trouble is that mainstream economics shades too easily into ideology, constraining the choices that we appear to have and providing cookie-cutter solutions. A proper understanding of the economics that lies behind neoliberalism would allow us to identify—and to reject—ideology when it masquerades as economic science. Most importantly it would help us develop the institutional imagination we badly need to redesign capitalism for the twenty-first century.”

Interesting presentation by Stansbury and Summers.

Roads or schools? It’s a question akin to the “guns or butter” choice that governments around the world confronted in the 20^th century: How to spend a nation’s finite resources to produce the maximum benefit for its people. A new IMF working paper finds that low-income countries tend to spend less on schools than on roads as a share of GDP.

“In the presence of distortionary taxation and debt aversion, the different pace at which roads and schools contribute to economic growth turns out to be central to this decision. Specifically, while costs are front-loaded for both types of investment, the growth benefits of schools accrue with a delay. To put things in perspective, with a ‘big push’, even assuming a large (15 percent) return differential in favor of schools, the government would still limit the fraction of the investment scale-up going to schools to about a half. Besides debt aversion, political myopia also turns out to be a crucial determinant of public investment composition. A ‘big push’, by accelerating growth outcomes, mitigates myopia—but at the expense of greater risks to fiscal and debt sustainability. Tied concessional financing and grants can potentially mitigate the adverse effects of both debt aversion and political myopia”

From a new IMF working paper: “In this study, we document the decline in income inequality and a convergence in consumption patterns in Brazilian states in a new database constructed from micro data from the national households’ survey. We adjust the state-Gini coefficients for spatial price differences using information on households’ rental prices available in the survey. In a panel regression framework, we find that labor income growth, formalization, and schooling contributed to the decline in inequality during 2004−14, but redistributive policies, such as Bolsa Família, have also played a positive role. Going forward, it will be important to phase out untargeted subsidies, such as public spending on tertiary education, and contain growth of public sector wages, to improve budgetary efficiency and protect gains in equality.”
