Colonial Legacy, State-Building and the Salience of Ethnicity in Sub-Saharan Africa

(with Merima Ali, Odd-Helge Fjeldstad, Boqian Jiang)

  The Economic Journal, forthcoming. Download.

Abstract

 

African colonial history suggests that British colonial rule may have undermined state centralisation due to legacies of colonial segregation across ethnic groups and stronger executive constraints. Using micro-data from sub-Saharan Africa, we find that anglophone (as opposed to francophone) citizens report a weaker sense of national identity (relative to their ethnic identity). The findings also hold among observations near anglophone--francophone borders, both across countries and within Cameroon. Evidence from taxation, security and the power of chiefs also suggests weaker state capacity in anglophone countries. These results highlight the legacy of colonial rule on state-building.

The Dual Policy in the Dual Economy -- The Political Economy of Urban Bias in Dictatorial  Regimes

Journal of Development Economics, Volume 105, p. 77-85, November 2013 Download

Abstract

 

In many developing countries, public resource allocation is often biased against the rural population. Since a vast majority of the poor live in rural areas, the bias is highlighted as one of the most important institutional factors contributing to poverty. This paper develops a political economy model of urban bias in a dictatorial regime. A novel result of the model is that urban bias can emerge in predominantly agrarian economies even if there is no bias in political power toward urban residents. The empirical evidence from a recently compiled country-level panel dataset on agricultural taxes/subsidies is consistent with the prediction of the model.

Does Agricultural Growth Cause Manufacturing Growth?

 Economica, Volume 82, p. 1107-1125, December 2015.  Download

Abstract

 

The role of agricultural development for industrialization is central to several theories of economic development and policy. However, empirically assessing the impact of agricultural growth on manufacturing growth is challenging because of endogeneity concerns. To address the identification challenge, I use random weather variations to instrument agricultural growth. The instrumental variable estimations show that agricultural growth has a significant positive impact on manufacturing growth. I discuss the empirical implications for efficiency of the manufacturing sector and the role of agriculture in Africa's industrialization.

Should Developing Countries Constrain Resource-Income Spending? A Quantitative Analysis of Oil Income in Uganda

Abstract

 

A large increase in government spending following resource discoveries often entails political risks, inefficient investments and increased volatility. Setting up a sovereign wealth fund with a clear spending constraint may decrease these risks. On the other hand, in a capital scarce developing economy with limited access to international borrowing, such a spending constraint may lower welfare by reducing domestic capital accumulation and hindering consumption increases for the currently poor. These two contradicting considerations pose a dilemma for policy makers in deciding whether to set up a sovereign wealth fund with a spending constraint. Using Uganda's recent oil discovery as a case study, this paper presents a quantitative macroeconomic analysis and examines the potential loss of constraining spending through a sovereign wealth fund with a simple spending rule. We find that the loss is relatively low and unlikely to dominate the political risks associated with increased oil spending. Thus, such a spending constraint appears well warranted.

Abstract

Weak fiscal capacity for domestic resource mobilization is the hallmark of poor countries. Recently, many developing countries resorted to the application of information technology to consolidate tax mobilization; however, there is little systematic empirical evidence on the impact of such reforms. We attempt to narrow this gap by documenting evidence from Ethiopia where there has been a recent surge in the use of electronic sales register machines (ESRMs). Using a unique large-scale administrative data-set covering all business taxpayers, we find that the adoption of ESRMs was followed by significant increases in reported sales and tax payments. Moreover, we find a positive effect on employment and no effect on net entry, suggesting that increased tax payments by registered taxpayers occurred without erosion of the tax base.

Economic Growth and Trade in Human Capital

  Download .

Abstract

A salient empirical pattern in the East Asian “miracle” is a large increase in output and factor accumulation (both human and physical capital) despite only a modest increase in TFP. I present a model of growth and economic catch-up that provides a possible explanation. A novel element of the model is a global market for education that allows for human capital transfer from frontier to developing economies. This assumption is motivated by the fact that during the technological catch-up of countries like Korea and Taiwan, domestic universities usually relied on graduates of Western universities to provide advanced training in science and engineering. Calibration of the model using plausible parameter values from the literature and the data suggests that the human capital transfer channel can substantially amplify the impact of a TFP increase.

Urban Bias and the Political Economy of Rural Land Policy in China

(with Wei Xiao)  Download.

Submitted

Abstract

The property rights of rural land remain significantly restricted in China. Given its implications for broad swaths of the economy, rural land reform remains a central issue in the political economy of China. This paper presents a political economy model of rural land policy, taking some salient characteristics of China's context into account. We consider an urban-biased political regime that faces the conflicting motives of industrializing the economy and controlling rural--urban migration. The model shows that while a higher level of urbanization provides stronger incentives in favor of land reform, an increase in the productivity of the urban sector has a counteracting effect. These effects are mediated by the labor elasticity of urban output, the income share of labor in the rural sector and the political power of urban residents. The model sheds light on how the modernization of China's economy could affect the prospects for land reform.

Trade in Human Capital

Abstract

For a developing economy transitioning into knowledge-intensive sectors, the lack of capacity for advanced education poses a natural challenge. We present a stylized quantitative model of trade in high-skilled human capital, in which colleges in a developing country can hire high quality teachers from a developed country. In the model, the use of foreign teachers is proposed as a possible mechanism to build domestic capacity for advanced education. Quantitative calibrations of the model show two main results. First, there are significant frictions in human capital trade, as measured by the wedge between the level of human capital observed in the data versus the level simulated under the assumption of no frictions. Removal of the wedge can narrow average income gap between the United States and other countries by about 14%. Second, relative to countries with the lowest and highest incomes, middle-income countries appear to gain the most from removal of the wedge.

 

Urban Bias in Capital Allocation: Evidence from China

(with Piyusha Mutreja, Wei Xiao)

Under review

 

Abstract

Even though urban bias in resource allocations, wherein governments neglect their rural population in favor of urban residents, is often considered as a crucial concern in autocratic states, empirical evidence on existence of such a bias remains limited. In this paper, using micro data on firms from urban and rural areas of China, we measure the extent and patterns of urban bias in capital allocation. First, we find that urban firms appear to have cheaper access to capital. Second, this urban-rural gap is primarily driven by state-owned enterprises, suggesting that allocation choices by the state, as opposed to investment constraints faced by private rural enterprises, represent the more relevant factor for the underinvestment of capital in rural areas. Exploiting the regional variation across Chinese prefectures, we also document how the urban-rural gap in capital allocation varies across important market and political factors, such as the level of financial development, the geographic proximity of the urban area to centers of power, and the level of state control over the local economy.

Colonial Origins and the Persistence of Customary Land Tenure

Under review

 

Abstract

In many communities, chiefs wield significant influence in land allocation. Scholars of African colonial history often emphasize the role of British colonial rule in entrenching the control of chiefs over land resources. Using micro data on a survey of adult citizens from anglophone and francophone countries in sub-Saharan Africa, we find a highly robust empirical pattern in support of this thesis. Chiefs are more likely to be in charge of land allocation in anglophone countries, as compared to francophone countries. This result holds across various specifications, including discontinuity analysis focusing on observations near anglophone--francophone borders. The finding highlights the potentially persistent effect of colonial rule on contemporary land institutions.

The Corruption of Local Elites in Anglophone and Francophone Africa

(with Merima Ali, Odd-Helge Fjeldstad) 

Abstract

African colonial history is considered to have profound implications for postcolonial economic and institutional outcomes. The British native administration (compared to the French one) instituted a system of indirect colonial rule that bolstered the control of chiefs over their population, strengthened their power to dispense patronage, and hence, weakened the preexisting formal and informal mechanisms of checks that could curb abuse of their power. However, its legacy on accountability of chiefs (local elites) remains underexplored. Using microdata from francophone and anglophone countries in sub-Saharan Africa, we examine the empirical association between British colonial rule (as compared to French rule) and the accountability of chiefs, as measured by the corruption of chiefs and the level of public trust in them. We find that the level of corruption among anglophone chiefs is significantly higher than that of francophone chiefs, and that respondents in anglophone countries have a significantly lower level of trust in chiefs. These results remain robust to including a wide array of controls. They also hold for the sample of all observations in our data, as well as observations in a discontinuity analysis near the anglophone–francophone national borders, including those in ethnic historical homelands that were split between francophone and anglophone countries..
