Friday Roundup: DeLong on Piketty, Gentzkow wins Bates Medal, Mobile Money, and Remittances in Africa

LTD Editors's picture

Equitablog, run by the Washington Center for Equitable Growth, has launched a series of 'Notes and Finger Exercises on Thomas Piketty’s “Capital in the Twenty-First Century.' Brad DeLong's post, 'There Are Four r’s', details some alleged oversights in Piketty's book. In particular, DeLong focuses on how the real interest rate behaves at different levels of economic activity. He highlights Larry Summers' concern about secular stagnation and the risk that rich folks might retreat from investing in industry. And DeLong pulls out some sexy math.

Matthew Gentzkow has won the John Bates Clark Medal, an honor conferred by the American Economic Association for his contributions to "our understanding of the economic forces driving the creation of media products, the changing nature and role of media in the digital environment, and the effect of media on education and civic engagement..."

Poverty reduction, growth, and movements in income distribution

Jos Verbeek's picture

Last week the President of the World Bank Group launched at the Spring Meetings the report "Prosperity for All." One of the interesting areas the note reported on was the interrelationship between growth, movements in the income distribution and poverty reduction.

There are various ways of showing the impact of growth on people’s income and its interrelationship with a country’s income distribution.  In comparing distributions over time, one of the more useful graphs is a Pen’s Parade (figure 1a), named after another Dutch economist as so many inequality or poverty measures are (other examples are the Theil index and Thorbecke for the Foster-Greer-Thorbecke Poverty Measure).

Why don't poor countries do R&D?

William Maloney's picture

Poor countries invest far less in research and development (R&D) as a share of their GDP than rich countries. Even middle income countries often invest well under 0.5%, compared to 3% and above in advanced countries.  

This fact poses a profound development mystery, and at the surface, suggests huge missed opportunities. Estimates of the social rates of return to R&D - often above 40% - in advanced countries are so high, as to justify levels of investment in developing countries that are multiples greater than those actually found. The case appears to be particularly strong for poor countries, where R&D is essential to the "absorptive'' or "national learning'' capacity that is needed to exploit technological advance originating from rich countries. 

Dynamic Effects of Microcredit in Bangladesh

With the phenomenal growth of microfinance institutions representing 30 million members with over $2 billion of annual disbursement over the past two decades, it is important to understand the dynamics of microcredit expansion and its induced impact on household welfare. A new World Bank working paper by Shahidur R. Khandker and Hussain A. Samad uses long panel survey data spanning over 20 years to examine the dynamics of microcredit programs in Bangladesh.

 Steven Shapiro / World BankPresident Jim Yong Kim, Prof Jeff Sachs, Chief Economist Kaushik Basu and Annie Lowrey of the New York Times participated in a panel last Friday titled 'Sharing Prosperity, Delivering Results.'

The four discussed the challenges of achieving the World Bank Group's goals of ending extreme poverty and boosting shared prosperity, and in so doing, all stressed the need to take on the goals with an activist's zeal.

Friday round up: Spring Meetings at the WB and IMF

LTD Editors's picture

From calling for a Data Revolution to analyzing the power of migration and development, to sharing prosperity and the moral imperative of ending poverty and discrimination, there are a dizzying array of events, meetings and ideas buzzing at this week's Spring Meetings of the WB and IMF.

On Data, you can watch the webcast of an event at the Bank where Jim Jong Kim, the Chief Economist of the AFDB and Haishan Fu of the Data Group in the Development Economics Vice Presidency spoke of their vision for better statistics harnessed for the greater good. Also, David Roodman has a compelling post on what it will take to overhaul methods of data collection and donor as well as country coordination.

Of Oxfam, inequality, public services and twinning

Dean Mitchell Jolliffe's picture

Last week, Oxfam released a powerful report on inequality, “Working for the Many: Public services fight inequality.” The report makes a persuasive case for the need to bring more attention to the issue of inequality in policy discussions. Indeed, at the recent World Economic Forum Annual Meeting, World Bank President Jim Yong Kim stated that “at Davos, income inequality should be front and center” as an important item on the global agenda. I was recently a discussant in a session on the Oxfam report at a Spring Meetings event alongside Max Lawson of Oxfam Great Britain and David Coady of the IMF's Fiscal Affairs Department. The case Oxfam makes that inequality is harmful to the global economy is well articulated and their prescription for a solution is highly focused: increase the amount of progressive taxation to fund free and universal health and education.  In the following slides, I provide a few examples of where we might want to broaden our thinking on the issue of inequality. In particular, I offer a couple of illustrations where a singular focus on inequality would lead us to undervalue some very important progress that has been made in the fight to eliminate poverty. In contrast, by ‘twinning’ the goals of eliminating extreme poverty and boosting shared prosperity, the policies we design may be more likely to ensure that everyone shares in growth and prosperity.

Emerging market sovereign bonds: Does it cost more to issue a bond under the English law?

Dilip Ratha's picture

It seems it does. During 2008-2012, post-crisis, launching under English law increased spreads by more than a third on average. In other words, by choosing the UK law, a nation rated B+ (for example, Ecuador, Ghana, Greece, Pakistan and Zambia) apparently paid 7.7% interest rate per annum instead of 6 percent, and a nation rated BB (for example, Bangladesh, Nigeria, Serbia or Vietnam) paid nearly 5.7% instead of 4.5% (figure 1). Such an increase in spread is equivalent to a rating downgrade of 3 notches or more.

When firefighting is not enough: The humanitarian community needs better risk management

Rasmus Heltberg's picture

A new report by the United Nations Office for Coordination of Humanitarian Affairs (OCHA) Saving Lives Today and Tomorrow is a wakeup call to the humanitarian community to improve risk management. The report builds on and has several parallels to the World Development Report (WDR) 2014 on Risk and Opportunity: Managing Risk for Development, and I was therefore invited to speak at its UN launch in New York last week.

New Working Paper by Aart Kraay and David McKenzie: Do poverty traps exist?

LTD Editors's picture

This paper reviews the empirical evidence on the existence of poverty traps, understood as self-reinforcing mechanisms through which poor individuals or countries remain poor. Poverty traps, understood as self-reinforcing mechanisms through which poor individuals or countries remain poor, have captured the interest of many development policy makers, because poverty traps provide a theoretically coherent explanation for persistent poverty. They also suggest that temporary policy interventions may have long-term effects on poverty. However, a review of the reduced-form empirical evidence suggests that truly stagnant incomes of the sort predicted by standard models of poverty traps are in fact quite rare.
