Abstract:
This paper addresses two important economic issues for Africa: the contribution of national borders and ethnicity to market segmentation and integration between and within countries. Market pair regression analysis provides evidence of higher conditional price dispersion for both a grain and a cash crop between markets separated by the Niger-Nigeria border than between two markets located in the same country. A regression discontinuity analysis also confirms a significant price change at the international border. The international border effect is lower, however, if the cross-border markets share a common ethnicity. Ethnicity is also linked to higher price dispersion within Niger; we find a significant intranational border effect between markets in different ethnic regions of the country. This suggests that ethnic similarities diminishing international border effects could enhance international market integration, and ethnic differences could contribute to intranational market segmentation in sub-Saharan Africa. We provide suggestive evidence that the primary mechanism behind the internal border effect is related to the role of ethnicity in facilitating access to credit in agricultural markets. We argue that the results are not driven by differences in price volatility or observables across borders.

12. The Place Premium: Wage Differences for Identical Workers across the U.S. Border - Working Paper 148

Abstract:
We compare the wages of workers inside the United States to the wages of observably identical workers outside the United States—controlling for country of birth, country of education, years of education, work experience, sex, and rural-urban residence. This is made possible by new and uniquely rich microdata on the wages of over two million individual formal-sector wage-earners in 43 countries. We then use five independent methods to correct these estimates for unobserved differences between the productivity of migrants and non-migrants, as well as for the wage effects of natural barriers to international movement in the absence of policy barriers. We also introduce a selection model to estimate how migrants' wage gains depend on their position in the distribution of unobserved wage determinants both at the origin and at the destination, as well as the relationship between these positions. For example, in the median wage gap country, a typical Bolivian-born, Bolivian-educated, prime-age urban male formal-sector wage worker with moderate schooling makes 4 times as much in the US as in Bolivia. Following all adjustments for selectivity and compensating differentials we estimate that the wages of a Bolivian worker of equal intrinsic productivity, willing to move, would be higher by a factor of 2.7 solely by working in the United States. While this is the median, this ratio is as high as 8.4 (for Nigeria). We document that (1) for many countries, the wage gaps caused by barriers to movement across international borders are among the largest known forms of wage discrimination; (2) these gaps represent one of the largest remaining price distortions in any global market; and (3) these gaps imply that imply allowing labor mobility can reduce a given household's poverty to a much greater degree than most known in situ antipoverty interventions.

13. Nigeria: Ogoni Land after Shell

Publication Date:

International Crisis Group
Abstract:
The Nigerian government's 4 June 2008 decision to replace the Shell Petroleum Development Company (SPDC) as operator of oil concessions in Ogoni areas offers an opportunity for ending one of the longest-running conflicts between a multinational oil company and a local community in the Niger Delta. But to ensure that new friction does not develop between the Ogoni and Shell's successor company, it must be followed by a comprehensive program of consultations with local populations to address the remaining issues involved in oil production in this area, including environmental protection and distribution of revenues.

Abstract:
In 1965, the growth rate of per capita GDP in Niger and Nigeria was 2.1 percent and 4.2 percent, respectively, and 2.9 percent in Botswana. From 1966 to 1969, however, Niger and Nigeria recorded a negative growth rate, while Botswana continued to experience a positive growth rate over the same period. In 1990, the growth rate of per capita GDP was 1 percent in Ghana and 5.2 percent in Nigeria. Yet, from 1991 to 1994, the growth rate was negative in Nigeria and positive in Ghana. Why does the trajectory of economic growth episodes differ among countries? In other words, why is economic growth more sustainable in some countries than in others?

15. Nigeria's Economic Reforms Progress and Challenges

Abstract:
Following years of economic stagnation, Nigeria embarked on a comprehensive reform program during the second term of the Obasanjo administration. The program was based on the National Economic Empowerment and Development Strategy (NEEDS) and focused on four main areas: improving the macroeconomic environment, pursuing structural reforms, strengthening public expenditure management, and implementing institutional and governance reforms. This paper reviews Nigeria's recent experience with economic reforms and outlines major policy measures that have been implemented. Although there have been notable achievements under the program, significant challenges exist, particularly in translating the benefits of reforms into welfare improvements for citizens, in improving the domestic business environment, and in extending reform policies to states and local governments. Consequently, we argue that the recent reform program must be viewed as the initial steps of a much longer journey of economic recovery and sustained growth. This paper concludes by outlining a number of outstanding issues that future Nigerian administrations must address.

Abstract:
Nigeria's vital importance for Africa's political development, for U.S. and European interests, and for world order cannot be exaggerated. Nigeria's sheer aggregate numbers—possibly as many as 150 million of the full continent's 800 million—and its proportionate weight in sub-Saharan Africa' s troubled affairs, make the country's continuing evolution from military dictatorship to stable, sustained democracy critical.

17. Nigeria's Faltering Federal Experiment

Publication Date:

Content Type:
Working Paper
Institution:
International Crisis Group
Abstract:
Nigeria's federal system and politics are deeply flawed, contributing to rising violence that threatens to destabilise one of Africa's leading countries. Failing to encourage genuine power sharing, they have sparked dangerous rivalries between the centre and the 36 states over revenue from the country's oil and other natural resources; promoted no-holds-barred struggles between interests groups to capture the state and its attendant wealth; and facilitated the emergence of violent ethnic militias, while politicians play on and exacerbate inter-communal tensions to cover up their corruption. The government has been quick to brand many of the symptoms, especially the rise of militancy, as simple criminality to be dealt with by more police and more troops. But unless it engages with the underlying issues of resource control, equal rights, power sharing and accountability, Nigeria will f ace an internal crisis of increasing proportions.

18. Nigeria: Want in the Midst of Plenty

Publication Date:

Policy Brief
Institution:
International Crisis Group
Abstract:
Nigeria is Africa's most populous nation and perhaps also its most poorly understood. It has endured six successful and numerous failed military coups, a civil war that cost well over a million lives, three inconclusive transitions to democracy and recurrent factional violence. Despite more than $400 billion in oil revenue since the early 1970s, the economy under performs, and the great majority of citizens have benefited little. More effective institution building is imperative.

Working Paper
Institution:

Abstract:
The paper examines the source of financial market fragmentation in sub-Saharan Africa in the framework of institutional economics. Based on fieldwork data from Ghana, Malawi, Nigeria, and Tanzania, it analyses financial risk management, the transaction costs for loan screening and monitoring, and contract enforcement. It shows how, faced with various institutional constraints, the range of clientele selected by formal and informal lenders becomes both narrow and at the extreme market-ends. It evaluates the prevailing state of managing risks for market structure, and binding institutional constraints for market transformation and deepening in sub-Saharan Africa.

20. Tax Policy Reforms in Nigeria

Author:

Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
Nigeria is governed by a federal system, hence its fiscal operations also adhere to the same principle, a fact which has serious implications on how the tax system is managed. The country's tax system is lopsided, and dominated by oil revenue. It is also characterized by unnecessarily complex, distortionary and largely inequitable taxation laws that have limited application in the informal sector that dominates the economy. The primary objective of this paper is to prepare a case study on tax policy reforms in Nigeria, with the specific objectives of examining the main tax reforms in the country; highlighting tax revenue profile and composition; analysing possible distributional impacts on the poor; discussing major problems that could prevent effective tax implementation in the country; and offering suggestions for reforms.
