Nunn N, Qian N. The Determinants of Food Aid Provisions to Africa and the Developing World. In: Edwards S, Johnson S, Weil DN African Successes: Sustainable Growth. Vol. IV. Chicago, IL: University of Chicago Press ; 2016. pp. 161-178.Abstract

We examine the supply-side and demand-side determinants of global bilateral food aid shipments between 1971 and 2008. First, we find that domestic food production in developing countries is negatively correlated with subsequent food aid receipts, suggesting that food aid receipt is partly driven by local food shortages. Interestingly, food aid from some of the largest donors is the least responsive to production shocks in recipient countries. Second, we show that U.S. food aid is partly driven by domestic production surpluses, whereas former colonial ties are an important determinant for European countries. Third, amongst recipients, former colonial ties are especially important for African countries. Finally, aid flows to countries with former colonial ties are less responsive to recipient production, especially for African countries. 

Nunn N, Trefler D. Domestic Institutions as a Source of Comparative Advantage. In: Gopinath G, Helpman E, Rogoff K Handbook of International Economics. Vol. 4. North Holland ; 2014. pp. 263-315.Abstract

Domestic institutions can have profound effects on international trade. This chapter reviews the theoretical and empirical underpinnings of this insight. Particular attention is paid to contracting institutions and to comparative advantage, where the bulk of the research has been concentrated. We also consider the reverse causation running from comparative advantage to domestic institutions.

Nunn N. Gender and Missionary Influence in Colonial Africa. In: Akyeampong E, Bates R, Nunn N, Robinson JA Africa's Development in Historical Perspective. New York: Cambridge University Press ; 2014. pp. 489-512.Abstract

Using information on the locations of Catholic and Protestant missions during Africa’s Colonial period, I test whether Protestant and Catholic missionaries differentially promoted the education of males and females. I find that while both Catholic and Protestant missions had a positive long-run impact on educational attainment, the impacts by gender were very different. Protestant missions had a large positive impact on the long-run education of females and a very small impact on the long-run education of males. In contrast, Catholic missions had no impact on the long-run education of females, but a large positive impact on the education of males. These findings are consistent with the greater importance placed on the education of women by Protestants relative to Catholics.

Nunn N. Historical Development. In: Aghion P, Durlauf S Handbook of Economic Growth. Vol. 2. North-Holland ; 2014. pp. 347-402.Abstract

This chapter surveys a growing body of evidence showing the impacts that historical events can have on current economic development. Over the past two decades historical persistence has been documented in a wide variety of time periods and locations, and over remarkably long time horizons. Although progress continues to be made identifying and understanding underlying mechanisms, the existing evidence suggests that cultural traits and formal institutions are both key in understanding historical persistence.

Nunn N. Shackled to the Past: The Causes and Consequences of Africa's Slave Trade. In: Diamond J, Robinson JA Natural Experiments of History. Cambridge: Harvard University Press ; 2010. pp. 142-184.Abstract

This chapter uses statistical techniques to assess whether there is evidence that Africa’s slave trades had a detrimental impact on long-term economic development. This is done by first constructing estimates of the number of slaves taken from each region of Africa between 1400 and 1900. The estimates are constructed by combining data on the number of slaves shipped from African ports with data from historical records reporting the ethnic identities of slaves taken from Africa. Using the constructed data, it shown that the parts of the continent from which the largest number of slaves were taken in the past are the parts of the continent that are the poorest today. This relationship is found to be extremely robust. It remains even when other important determinants of economic development are taken into account.

This relationship can be interpreted a number of ways. One interpretation is that it shows that the slave trades had an adverse effect on Africa’s long-term economic development. An alternative interpretation, however, is that the parts of Africa from which the largest number of slaves were taken in the past were initially the least developed. And because these characteristics persist today, these parts of Africa continue to be the least developed. Therefore, we observe that the parts of Africa that exported many slaves in the past are also poor today, even though the slave trades did not cause these areas to become underdeveloped. This alternative explanation is tested in the data by examining whether it was in fact the initially least developed parts of Africa that exported the greatest number of slave. Consistent with the historical evidence, the data suggest that the parts of Africa that were initially the most developed, not the least developed, supplied the largest number of slaves. This evidence provide strong evidence against the second interpretation, and instead supports the first interpretation. It is also shown that additional statistical tests, using instrumental variables, also provides additional support for the slave trades having a causal adverse effect on economic development within Africa.

Nunn N. Slavery, Inequality, and Economic Development in the Americas: An Examination of the Engerman-Sokoloff Hypothesis. In: Helpman E Institutions and Economic Performance. Cambridge: Harvard University Press ; 2008. pp. 148-180.Abstract

Recent research argues that among former New World colonies a nation’s past dependence on slave labor was important for its subsequent economic development (Engerman and Sokoloff, 1997, 2002). It is argued that specialization in plantation agriculture, with its use of slave labor, caused economic inequality, which concentrated power in the hands of a small elite, adversely affecting the development of domestic institutions needed for sustained economic growth. I test for these relationships looking across former New World economies and across states and counties within the U.S. The data shows that slave use is negatively correlated with subsequent economic development. However, there is no evidence that this relationship is driven by large scale plantation slavery, or that the relationship works through slavery’s effect on economic inequality.

Nunn N, Trefler D. The Boundaries of the Multinational Firm: An Empirical Analysis. In: Helpman E, Marin D, Verdier T The Organization of Firms in a Global Economy. Cambridge: Harvard University Press ; 2008. pp. 55-83.Abstract

Using data on U.S. intra-firm and arm’s-length imports for 5,423 products and 210 countries, we examine the determinants of the share of U.S. imports that are intra-firm. Three determinants of this share have been proposed: (1) Antràs (2003) focuses on the share of inputs provided by the headquarter firm. We provide added confirmation and further strengthen the empirical findings in Antràs (2003) and Yeaple (2006). (2) In a model featuring heterogeneous productivities, Antràs and Helpman (2004) focus on the interaction between the firm’s productivity level and the headquarter’s input share. We find very strong support for this determinant. (3) Antràs and Helpman (2006) add to this the possibility of partially incomplete contracting. We find that consistent with the novel prediction of their model, improved contracting of the supplier’s inputs can increase the share of U.S. imports that are intra-firm. In short, the data bear out the primary predictions of this class of models about the share of U.S. imports that is intra-firm trade.

Akyeampong E, Bates RH, Nunn N, Robinson JA. Africa's Development in Historical Perspective. New York: Cambridge University Press; 2014. Publisher's LinkAbstract

This edited volume addresses the root causes of Africa's persistent poverty through an investigation of its longue durée history. It interrogates the African past through disease and demography, institutions and governance, African economies and the impact of the export slave trade, colonialism, Africa in the world economy, and culture's influence on accumulation and investment. Several of the chapters take a comparative perspective, placing Africa's developments aside other global patterns. The readership for this book spans from the informed lay reader with an interest in Africa, academics and undergraduate and graduate students, policy makers, and those in the development world.
