Regional Trade Arrangements in Africa: Past Performance and the Way Forward

Abstract: Regional trade arrangements (RTAs) in Africa have been ineffective in promoting trade and foreign direct investment. Relatively high external trade barriers and low resource complementarity between member countries limit both intra‐ and extraregional trade. Small market size, poor transport facilities and high trading costs make it difficult for African countries to reap the potential benefits of RTAs. To increase regional trade and investment, African countries need to undertake more broad‐based liberalization and streamline existing RTAs, supported by improvements in infrastructure and trade facilitation. Early action to strengthen the domestic revenue base would help address concerns over revenue losses from trade liberalization.     

Revenue Mobilization in African Countries: Does Natural Resource Endowment Matter?*

Abstract: Natural resource endowment offers great opportunities for achieving high levels of growth and development, notably via fiscal revenue mobilization throughout the entire chain of operations from exploration to production to exports. In the case of African countries, however, resource‐rich countries have not yet been able to take full advantage of their resource wealth to mobilize government revenue. In fact it appears that they have often been outperformed by their resource‐scarce counterparts in this regard. Is the low revenue performance a result of distorted incentives induced by the natural resource bonanza or the lack of capacity to harness the revenue potential from the natural resource industry? This paper explores these questions and provides some empirical evidence based on data from a sample including African countries as well as countries from Latin America, Asia, and the Middle East for the period 1980–2007. The paper undertakes an econometric analysis to examine the factors that determine revenue performance in African countries from a comparative perspective, with a focus on the role of natural resource endowment. The results are consistent with the evidence from the literature, especially with regard to the role of economic structure (notably the share of agriculture in GDP), the tax base (per capita income), and trade. We compute an index of revenue performance that relates the actual revenue to the level predicted by the econometric model and we find that African resource‐rich countries have performed poorly relative to their resource‐scarce counterparts and compared to the oil‐rich Middle Eastern countries. The paper concludes with some policy implications for African countries.     

Impact of Public Investment on Private Investment in Sub‐Saharan Africa: Crowding In or Crowding Out?

This paper investigates the possible crowding‐in or crowding‐out effect of public investment on private investment in sub‐Saharan Africa. While this relationship has been theoretically and empirically studied in the literature, most studies used traditional panel fixed effects or Generalized Method of Moments estimators which can potentially lead to biased and inconsistent estimates. We employ heterogeneous parameter models, including the Mean Group, the Common Correlated Effects Mean Group Model, and the Augmented Mean Group estimators, to incorporate the possibility of slope heterogeneity and the presence of cross‐sectional dependence. Using a large sample of 44 sub‐Saharan African countries over the period 1960–2015, we find that on average public investment crowds in private investment in sub‐Saharan Africa. We also find that the impact differs between countries and is higher in countries with a strong private sector.     

China's value-added tax reform, capital accumulation, and welfare implications

This paper analyzes the effects of China's upcoming value-added tax (VAT) reform of removing investment from the tax base on capital accumulation and the welfare of the rich and the poor. Three alternative methods to make up for the loss of tax revenue are considered. The VAT reform with consumption tax being endogenous increases capital accumulation and the utility of both the rich and the poor. The VAT reform with the labor income tax rate being endogenous increases capital accumulation; and it decreases the utility of the rich and increases the utility of the poor (increases the utility of both the rich and the poor) if the rich has a higher rate or the same rate of time preference (if the rich has a lower rate of time preference). The VAT reform, accompanied by a cut in transfers to the poor, has no effect on capital accumulation if the rich and the poor have the same rate of time preference; it decreases (increases) capital accumulation if the rich has a higher (lower) rate of time preference; and it increases the utility of the rich and decreases the utility of the poor.     

Analysis of tax effort in WAEMU: How important are institutional/administrative reforms?

This paper examines, in depth, the hypotheses explaining the tax effort of seven West African Economic and Monetary Union (WAEMU) countries over the period 1996–2018. The studies of Karakaplan and Kutlu were applied to the stochastic tax frontier model. This provides a new method for analyzing tax effort that solves potential endogeneity problems, especially those of income. This study confirms the positive impact of income, trade openness, urbanization, government capital spending and anticorruption on tax revenue mobilization, while the size of the agricultural sector has a negative impact on tax revenue. On the other hand, reforms of tax institutions have no effect on tax effort. The average tax revenue of the countries of the WAEMU is 11.34 and the average tax effort is estimated at 0.7901 over the period 1996–2018. Thus, these countries could achieve a tax revenue to GDP ratio of 13.72% if they fully exploit their potential.     

The impact of international agreements on domestic policy: An analysis of tariff policy in African countries

This paper estimates a fixed effects tariff model to study the impact of the tariff reform provisions of international agreements on domestic tariffs, using a sample of eight Sub-Saharan African countries. The structure of the model explaining domestic tariff changed from the preagreement period to the postagreement period. However, the results indicate that for the most part, efforts by governments to adhere to tariff agreements failed in all but a few countries. Even for the countries in which the agreements appeared to be successful, the significance of the results is relatively weak.     

Official Development Assistance and Foreign Direct Investment Flows to Sub‐Saharan Africa

Abstract: Foreign direct investment is believed to have a positive impact on the economies of the developing countries but its determinants are not yet fully established. This paper empirically investigates the relationship between official development assistances and foreign direct investment flows using panel data from 11 sub‐Saharan African countries for the period 1990–2003. The results show that bilateral official development assistance has a significant and positive influence on foreign direct investment flows. The results also show that trade openness, growth rate in the labor force, and exchange rates have a positive and significant effect on foreign direct investment flows. But multilateral development assistance, the growth rate in GDP per capita, the country's composite risk level, and the index for political freedom and civil liberties do not have a statistically significant effect on foreign direct investment flows. The policy implication of the positive and significant influence of the bilateral official development assistance on foreign direct investment is that the recipient countries need to formulate policies that improve their economic relationships with the donor countries in order to attract greater foreign direct investment flows from the multilateral corporations located in these countries.     

Effects of financial inclusion on tax revenue mobilization: Evidence from WAEMU countries

Financial inclusion remains at the heart of governments concerns. By creating favorable conditions for access to a diversified range of adapted financial products and services at affordable costs for the populations, financial inclusion generates important opportunities that could lead to increased tax revenue mobilization. This paper analyzes the effects of financial inclusion on tax revenue mobilization, using panel data from West African Economic and Monetary Union (WAEMU) countries over the period 2006–2019. The findings suggest that financial inclusion positively and significantly influences government's tax revenue. Moreover, by looking at the effects of disaggregated financial inclusion dimensions (access, use, and affordability) on various components of tax revenue, we find that the estimated coefficients on the subcomponents of financial inclusion are statistically significant. Results also indicate that the magnitude of effect of financial inclusion is higher on indirect taxes compared to direct tax revenues. This research recommends that policy-makers should prioritize financial inclusion in their policies and development agenda through National Financial Inclusion Strategies (NFIS) because it can increase countries' resource mobilization and help them to build fiscal resilience.     

Do International Remittances Affect Poverty in Africa?*

Abstract: International remittances flowing into developing countries are attracting increasing attention because of their rising volume and their impact on recipient countries. This paper uses a panel data set on poverty and international remittances for African countries to examine the impact of international remittances on poverty reduction in 33 African countries over the period 1990–2005. We find that international remittances—defined as the share of remittances in country GDP—reduce the level, depth, and severity of poverty in Africa. But the size of the poverty reduction depends on how poverty is being measured. After instrumenting for the possible endogeneity of international remittances, we find that a 10 percent increase in official international remittances as a share of GDP leads to a 2.9 percent decline in the poverty headcount or the share of people living in poverty. Also, the more sensitive poverty measures—the poverty gap (poverty depth) and squared poverty gap (poverty severity)—suggest that international remittances will have a similar impact on poverty reduction. The point estimates for the poverty gap and squared poverty gap suggest that a 10 percent increase in the share of international remittances will lead to a 2.9 percent and 2.8 percent decline, respectively, in the depth and severity of poverty in African countries. Regardless of the measure of poverty used as the dependent variable, income inequality (Gini index) has a positive and significant coefficient, indicating that greater inequality is associated with higher poverty in African countries, much in conformity with the literature. Similar results were obtained for trade openness. In the same vein, per capita income has a negative and significant effect on each measure of poverty used in the study. Our results also show that inflation rates positively and significantly affect poverty incidence, depth and severity in Africa. In all three poverty measures, the dummy variable for sub‐Saharan Africa is strongly positive, and strongly negative for North Africa. The policy implications of these results are discussed.     

Pass-through Effects of Global Commodity Prices on China＇s Inflation： An Empirical Investigation

The present paper uses a two-step approach to estimate the pass-through effects of changes in international commodity prices and the RMB exchange rate on domestic consumer price inflation in China. We first estimate the pass-through effects of international commodity prices on producer prices and then estimate the pass-through effects of producer price inflation on consumer price inflation. We find that a l O-percent increase in international commodity prices would lead to China＇ s producer prices increasing by 1.2 percent 3 months later, which in turn would increase China＇ s domestic inflation by 0.24 percent over the same period. However, a 10-percent appreciation of the RMB exchange rate against the US dollar would help to reduce increases in producer prices by 4.4 percent over the following 3 months, which in turn would lead to a 0. 89-percent decline in consumer price inflation over the same period. Our findings suggest that appreciation of the RMB in an environment of rising global commodity prices and a weak US dollar could be an effective instrument to help contain inflation in China.     

ESTIMATING EXCHANGE RATE AND BILATERAL TRADE BALANCE RELATIONSHIPS: THE EXPERIENCE OF SUB-SAHARAN AFRICAN COUNTRIES

This paper examines the effects of exchange rate changes on the bilateral trade balance of ten African countries vis‐à‐vis the US using annual data over period 1977‐2002. Both the Johansen and panel cointegration tests find cointegration among the series. The country FMOLS results show that real exchange rate depreciation improves the trade balance in six of ten countries in contrast to Tanzania in which it worsens the trade balance, with no effect found in Ghana, Morocco and Senegal. Foreign real income improves the trade balance in two countries but worsens it in another three. Finally, domestic real income negatively affects the trade balance in four countries but improves it in another three. The three‐panel coefficients are correctly signed and significant at the 1% level.     

SOUTH AFRICA AND THE NEW PARTNERSHIP FOR AFRICA'S DEVELOPMENT: ECONOMIC SPIN-OFFS AND LINKAGES

The New Partnership for Africa's Development (NEPAD) is a concerted effort by Africa's political leaders to develop a comprehensive and integrated strategic policy framework to raise current levels of socio‐economic development and reduce high levels of poverty across the African continent. The NEPAD framework recognises the need for African countries to pool their resources together in order to enhance regional development and economic integration. To this end, NEPAD emphasises capacity building and also seeks to solicit and disburse funds towards infrastructural development programmes and poverty alleviation projects, among others. South Africa's involvement with the rest of Africa has increased significantly since 1994. Trade exports, foreign direct investment (both market and resource‐seeking in nature) and public‐private partnerships have mushroomed in many parts of the continent. Many South African firms are providing the financial impetus for the infrastructural development and rehabilitation of African economies. This paper discusses salient economic linkages between South Africa and the rest of Africa within the framework of NEPAD. South Africa is the economic hub of sub‐Saharan Africa (and indeed of the African continent), with significant agricultural, manufacturing and services capacity. South African firms have invested in the development of a number of sectors in the rest of Africa, taking advantage of the new investment incentives offered by the NEPAD framework. The target sectors range from mining, the hospitality industry, engineering and construction, finance to telecommunications. These investments and economic involvements are crucial to the development of African countries and the relevant sectors that are important for the realisation of some of the objectives of NEPAD.     

Effects of cost sharing on the demand for physician services in Japan: Evidence from a natural experiment

In this paper, we investigate the effects of cost sharing on the demand for physician services in Japan by using a natural experiment, namely, the increase in the coinsurance rate for household heads in 1997. Our primary finding from the two-year data, which includes the transitory effects of the reform, is that the effects of the reform on the frequency of physician visits were negative and statistically significant, and that the effects of the reform on expenditures per visit were also negative. Based on these results, the arc elasticity of demand for physician services is ?0.055. When we exclude the transitory period using the three-year data, the effects of the reform on the frequency of physician visits turn to be positive. It seems that the patients marginally curtailed the number of physician visits immediately after the reform; however, this effect was not sustained in the six months after the reform. We conclude that Japanese patients are not very price sensitive within the 10–20 percent range of coinsurance rate. Another important finding in our study is that the decrease in expenditure per visit retained even after the transitory period. This result suggests that the existence of a possible moral hazard in the treatment intensity although the decision-making process on the treatment intensity needs to be examined more carefully.     

The Southern African customs union: A reappraisal

The paper attempts to evaluate, as far as possible quantitatively, the costs and benefits to the countries of the ‘Southern African periphery’ (Botswana, Lesotho and Swaziland) of participation with South Africa in the current customs union agreement. On balancing the agreement's measurable effects (on industrial development, exports, government revenue and the cost of living) against one another, it appears that on sanguine assumptions only, there would be a substantial benefit to Botswana and a much more moderate benefit to Lesotho if the customs union were dismantled and replaced by separately protected national markets. Such a calculation, however, neglects what may be the most important benefit and cost to the ‘peripheral’ countries of leaving the customs union, namely the increase of ‘economic independence’ and the risk of South African retaliation respectively: themes which are explored in the final section.

Retrospect of the Chinese Exchange Rate Regime after Reform： Stylized Facts during the Period from 2005 to 2010

In the present paper, we estimate the de facto RMB exchange rate regime, the currency basket, the floating band and the foreign exchange market pressure before and after the reform of the Chinese exchange rate regime in 2005. We find the following stylized facts： the value of the RAIB became stable after the reform; the weight of the US dollar remained high in the basket, while other currencies remained statistically significant; and the floating band gradually increased to lO percent during 2005-2008, and then greatly narrowed from the late summer of 2008 under the assumption of a yearly resetting interval. We find that the foreign exchange market pressure increased from 2005 to 2008. A possible reason is that the weight of the US dollar in the basket was slightly lower than the share of the US dollar in total transactions on the Chinese foreign exchange market. Therefore, it is reasonable for China to adopt a dollar peg exchange rate regime.     

Foreign Direct Investment and Trade Openness in Sub‐Saharan Economies: A Panel Data Granger Causality Analysis

This study uses annual balanced panel data for 25 sub‐Saharan African economies over the period 1977‐2009 to investigate the Granger causality relationship between trade openness and foreign direct investment (FDI) for the region. We took advantage of recent developments in econometric testing techniques for Granger noncausality heterogeneous panels that takes into consideration the effects of cross section dependence across the units of the panel data set to analyse the trade–FDI nexus in the region. The empirical result of this study reveals a bidirectional causal relationship between trade openness and foreign direct investment in sub‐Saharan economies. Concurrently, African countries should devote more emphasis for the promotion and attraction of FDI in order to expand their productive capacity to produce and export; in this way, by addressing supply‐side constraints, FDI will have positive multiplier effects on trade.     

The Global Setting and African Economic Growth

This paper reviews the evidence on the importance of the globalsetting for the economic growth of African economies, particularlyin the light of the increasing salience of globalisation. Althoughexport promotion strategies are found to be growth enhancingfor African economies, available evidence suggests that it isthe manufacturing component that really seems to matter. Theglobal-related factors with adverse effects include terms oftrade deterioration, economic instabilities of capital (investment)and imports, high world interest rates, real exchange rate misalignment,diminishing external aid flows into countries with sound policies,large external debt and high export taxes. The World Trade Organisationframework also matters for the growth prospects of African countries.The current time-bound exemptions accorded most African countriesunder the framework are steps in the right direction.     

US and China aid to Africa: Impact on the donor-recipient trade relations

This paper investigates the impact of the US and China's foreign aids to Africa on trade flows between donor and recipient countries. Evidence from the gravity model estimates reveals that the two donors' exports are strengthened by their aids to African partners. Interestingly, China's aid shows a positive effect on its total volume of trade and imports from Africa, while the aid from the US exhibits little impact on the US-Africa total trade and its imports from Africa. A possible explanation for such a difference could be due to the dissimilar national interests of donors in Africa. This study finally suggests that African countries should accelerate the pace of advancing domestic economies and rely less on foreign assistance, in order to establish a fairer and more equal international economic order.     

Competition among developing countries for foreign investment in the eighties — Whom did OECD investors prefer?

Conclusions Developing countries including the NIEs failed to maintain their shares in total foreign investment of all major OECD countries in the eighties. Shares were generally lower by 1988 than ten years ago. This negative trend can be observed for investment in manufacturing in particular, but also for non-manufacturing. Middle East and SubSaharan African countries came down to negligible shares, while shifts in shares mainly occurred between Latin America as a losing region and the Asian NIEs as winners. In absolute terms, however, Latin America remained a major host area. Within the regions, trends towards concentrating investment on few countries proliferated from Latin America where such concentration was traditionally high, to Asia with Singapore, Malaysia, Indonesia, and partly Hong Kong, in the lead. Against this background, home countries widely continued to maintain their traditionally preferred strongholds as did Japan in Southeast Asia, West Germany in Brazil and Argentina, the US in Latin America in general, and the UK in Commonwealth countries. Such patterns remained stable over time, but differed from each other.
