Tropical Agriculture: Is Africa Different?

We investigate the determinants of agricultural productivity in a panel of 27 tropical developing countries from 1984 to 2005 and test whether the coefficients of the right‐hand side variables are significantly different in sub‐Sahara Africa. We find evidence that the point estimates of fertilizer usage, telephones, tractor usage, rainfall and irrigation are positively and significantly related to agricultural productivity in the tropics. We also show that sub‐Saharan Africa is different in several respects. For instance, we find no evidence that fertilizer is associated with greater agricultural productivity in the African sample. Also, while the coefficient on infrastructure is positively associated with agricultural productivity in the full sample, its quantitative effect is smaller in sub‐Saharan Africa. As a robustness test, we experiment with an alternative measure of tropicality and find that the results are broadly similar.     

The anatomy of fragile states in Sub‐Saharan Africa: Understanding the interrelationship between fragility and indicators of wellbeing

According to most classifications, Sub‐Saharan Africa is the region of the world with the highest presence of fragile states. In this paper we examine the relationship between fragility and poverty, suggesting that countries may become trapped in a vicious circle of fragility and low levels of wellbeing. We consider fragility as a continuum and begin by reviewing available measures. These show the high presence of fragility in Sub‐Saharan Africa and allow the more fragile countries to be identified. There is seen to be a strong association between fragility, poor growth performance, and lower wellbeing in Sub‐Saharan Africa. Building on the strong evidence for the two‐way relationship between economic growth and poverty, we present an analysis of how the vicious circle linking poorer welfare outcomes and fragility may be able to be broken. We argue that building successful institutions is key here, and this can be enabled by specific policy interventions that are both poverty reducing and productive.     

Capital flight from sub‐Saharan Africa: linkages with external borrowing and policy options

Even as African countries became increasingly indebted, they experienced large‐scale capital flight. Some of this was legitimately acquired capital fleeing economic and political uncertainties; some was illegitimately acquired wealth spirited to safer havens abroad. This paper presents new estimates of the magnitude and timing of capital flight from 33 sub‐Saharan African countries from 1970 to 2004. We then analyze its determinants, including linkages to external borrowing. Our results confirm that sub‐Saharan Africa is a net creditor to the rest of the world, in that the subcontinent’s private external assets exceed its public external liabilities: total capital flight amounted to $443 billion (in 2004 dollars), compared to the external debt of $195 billion. Econometric analysis indicates that for every dollar in external loans to Africa in this period, roughly 60 cents flowed back out as capital flight in the same year, a finding that suggests the existence of widespread debt‐fueled capital flight. The results also show a debt‐overhang effect, as increases in the debt stock spur additional capital flight in later years. In addition to policies for recovery of looted wealth and repatriation of externally held assets, we discuss the need for policies to differentiate between legitimate and odious debts, both to ease current burdens on African countries and to improve international financial governance in the future.     

Taxation of International Private Capital Flows and Securities Transactions in Developing Countries: Do Public Finance Considerations Augment the Macroeconomic Dividends?

This paper examines policies to tax international private capital flows and securities transactions in developing countries. Many recent studies focus on the macroeconomic dividends associated with these policies (namely, their contribution to macroeconomic and financial stability and lengthened investor time horizons). In this paper I explore whether the potential of these policies to raise much‐needed tax revenues in developing countries augments their well‐known macroeconomic benefits. To my knowledge, there has been no effort to examine systematically the public finance issues related to the taxation of international private capital flows or securities transactions in the developing country context. I conclude that the public finance implications of these policies in middle‐income developing countries offers additional support to the macroeconomic case for them. To different degrees, taxation of international private capital flows and securities transactions has the potential to raise modest revenues in middle‐income countries. However, far more important is the potential of these policies to offer valuable macroeconomic dividends on the national level. These national macroeconomic dividends have the potential to bear fruit globally. This is because experiences with financial contagion over the last decade suggest that global financial stability can be enhanced via the promotion of domestic financial stability in developing countries.     

Natural Resource Exports,Fiscal Policy Volatility and Growth

The combination of poor institutions and erratic macroeconomic policy, as measured by the volatility of fiscal policy, is associated with slower growth. We show that macroeconomic policy is more erratic in countries that are rich in natural resources, especially minerals and fuels, and in those that receive large aid inflows. Poor institutions also play a role. Although Africa is a major receiver of aid and exporter of natural resources, this is not purely an African phenomenon. Output volatility is not associated with slower growth after controlling for institutions and the volatility of fiscal policy.     

Are Donor Countries Giving More or Less Aid?

The volume of foreign aid has increased during the last four decades, albeit with interruptions in certain years. Over time, the major recipients have changed: while the share of aid to Asia has diminished since the 1980s, that destined for sub‐Saharan Africa has grown. There is some evidence that, since the late 1990s, debt relief has assumed a larger share of the increased aid flows to sub‐Saharan Africa. The share of technical cooperation—a component of aid that is viewed as being driven by donors—has risen. More recently, there has been an increased emphasis on providing budget support to recipient governments, especially in the form of debt relief. Donor harmonization, national ownership of development plans, and sound policies on the part of the recipients are crucial for the aid to be effective in reducing poverty.     

The dynamics of financial development,globalisation, economic growth and life expectancy in sub‐Saharan Africa

The importance of life expectancy is recognised in the development economics literature because of its increasing effects on labour productivity and economic growth in long‐run. However, no published study to date empirically examines the nonlinear relationships between globalisation, financial development, economic growth and life expectancy in sub‐Saharan African (SSA) countries. Therefore, our study intends to fill this gap by using non‐parametric cointegration test and multivariate Granger causality test towards a non‐linear empirical understanding of the factors affecting the life expectancy. We consider the case of 16 sub‐Saharan African economies using annual data over the period 1970–2012. The empirical analysis indicates that financial development, globalisation and economic growth appear to have a positive impact upon life expectancy in sub‐Saharan African economies, except for Gabon and Togo. Our empirical findings may provide insightful policy implications towards improving population health conditions which are vital for promoting the productivity of labour force and long‐run economic growth in sub‐Saharan African countries. In light of these policy implications, governments should incorporate globalisation, financial development and economic growth as key economic instruments in formulating sustainable developmental policy to promote life expectancy for the people in sub‐Saharan African countries.     

Macroeconomic stabilization in developing economies: Are optimal policies procyclical?

Many empirical studies provide evidence that macroeconomic policies as well as capital flows exhibit procyclical characteristics in developing economies. In particular Kaminsky et al. [2004. When it rains, it pours: Procyclical capital flows and macroeconomic policies. NBER Macroeconomics Annual, MIT Press] demonstrate that a large group of middle-income countries run contractionary policies and experience capital flight during times of recession. This paper investigates the role of international financial markets in explaining these macroeconomic policy and capital flow characteristics. An optimal fiscal and monetary policy problem is formulated and solved for a small-open economy that faces a country-specific interest rate spread in international financial markets. It is found that, in the presence of the country spread, optimal fiscal and monetary policies as well as capital flows are procyclical under a reasonable parametrization. Optimal policies and capital flows turn countercyclical in the absence of the country spread. This pattern is robust to a range of alternative model specifications.     

The importance of composition of fiscal policy: evidence from different exchange rate regimes

We study the macroeconomic effects of fiscal policies in an open economy. We emphasize two transmission mechanisms: the cost channel, by which wage government spending and labor taxes raise the real wage firms must pay, and the exchange rate channel, by which the nominal exchange rate shifts induced by fiscal policy have real effects if (some) prices and wages are sticky. The latter channel implies that changes in wage government spending or in labor taxation should have different effects under flexible than under fixed exchange rates. In a 1964–93 panel of OECD countries we find significant evidence for both channels. Moreover, we find that the real product wage and profitability are more responsive than quantities (employment and output) to fiscal policy innovations.     

The impact of Africa‐China's diplomatic visits on bilateral trade

This article documents that African leaders’ state visits to China could stimulate China's exports to Africa in capital intensive manufacturing goods. We further find that state visits significantly increase official aid and exports by state‐owned enterprises to African countries which contribute to the trade growth after state visits.     

Assessing Recent Determinants of Borrowing Costs in Sub‐Saharan Africa

This study explores macroeconomic implications of the sovereign bond rush that has been taking place in sub‐Saharan Africa since 2006. The focus is on the sub‐Saharan sovereign bond yields as proxies for the region's ability to raise new funds on international markets. Despite the subcontinent's tour‐de‐force entrance to the international bond market, this paper reveals that recent (since early 2000s) borrowing in foreign currency is not without macroeconomic risk. Empirically this paper finds that sovereign bond yields are significantly influenced by global volatility, commodity prices and global liquidity—all factors that are out of the control of the sub‐Saharan economies in question. These findings suggest that portfolio repositioning by institutional investors prompted by improved growth prospects and implicit monetary policy tightening in the advanced economies or heightened risk perceptions, are likely to result in increased borrowing costs for the sub‐Saharan bond issuers and affect their ability to raise funds in international markets. Furthermore, a change in borrowing costs might lead to higher debt‐service costs and policy uncertainty, which in turn could lead to suboptimal investment levels and, ultimately, hinder economic development.     

Demographic and Economic Pressure on Emigration out of Africa*

Two of the main forces driving European emigration in the late nineteenth century were real wage gaps between sending and receiving regions and demographic booms in the low‐wage sending regions. Our new estimates of net migration for the countries of sub‐Saharan Africa show that exactly the same forces driving African across‐border migration are at work today. The results suggest that rapid growth in the cohort of potential young emigrants, population pressure on the resource base, and slow economic growth are likely to intensify the pressure for migration out of Africa and into high‐wage OECD countries over the next two decades.     

Impact of fiscal policy in an intertemporal CGE model for South Africa

This paper uses an intertemporal computable general equilibrium model to investigate the consequences of an expansive fiscal policy designed to accelerate economic growth in South Africa. A key contribution is made to existing literature on the transmission mechanism of fiscal policy in African economies. To the best of our knowledge, no published study has empirically analyzed the macroeconomic effects of fiscal policy in the context of an open, middle-income sub-Saharan African economy like South Africa using an integrated intertemporal model with such disaggregated production structure. The paper shows that an expansive fiscal policy would have a temporary impact on gross domestic product (GDP) but would translate into higher debt relative to GDP. Using increased taxation to finance the additional spending would lessen this impact but would also negatively affect macroeconomic variables. Increased investment spending would improve long-term GDP, under any financing scheme, and would decrease debt-to-GDP ratio as well as deficit-to-GDP ratio. This outcome is driven by the positive impact infrastructure has on total factor productivity. Sensitivity analysis shows that these conclusions are qualitatively similar for wide values of the elasticity of the total factor productivity to infrastructure. In fact, the conclusions hold even when comparing different financing schemes.     

How Significant Is Sub‐Saharan Africa's Demographic Dividend for Its Future Growth and Poverty Reduction?

Sub‐Saharan Africa will be undergoing substantial demographic changes over the next 15 years with the rising working‐age share of its population. The opportunity of African countries to convert these changes into demographic dividends for growth and poverty reduction will depend on several factors. The outlook will likely be good if African countries can continue the gains already made under better institutions and policies, particularly those affecting the productivity of labor, such as educational outcomes. If African countries can continue to build on the hard‐won development gains, the demographic dividend could account for 11–15% of gross domestic product (GDP) volume growth by 2030, while accounting for 40–60 million fewer poor in 2030. The gains can become more substantial with better educational outcomes that allow African countries to catch up to other developing countries. If the skill share of Africa's labor supply doubles because of improvements in educational attainment, from 25 to about 50% between 2011 and 2030, then the demographic dividends can expand the regional economy additionally by 22% by 2030 relative to the base case and reduce poverty by an additional 51 million people.     

Aid,institutions and economic growth in sub‐Saharan Africa: Heterogeneous donors and heterogeneous responses

This study contributes to the aid‐effectiveness debate using panel data from 43 sub‐Saharan African countries over the period 1980–2013. Its novelty lies in assessing the intermediary role of institutions and the importance of recipient and donor heterogeneity. The long‐run growth effect of (aggregate) aid from “traditional” donors is robustly non‐positive, and the indirect effect is negative. Disaggregation reveals donor heterogeneity. Chinese aid outperforms aggregate aid from traditional donors with respect to growth; however, it has a negative institutional effect. Recipient heterogeneity is largely a short‐run phenomenon, with only a few countries showing some deviations from shared long‐run parameter sets. Comparing donor behavior suggests that the future of aid would benefit more from focusing on quality – particularly, specialization and donor alignment.     

Economic Growth in a Cross‐section of Nonindustrial Countries: Does Colonial Heritage Matter for Africa?

The paper investigates the effects of Sub‐Saharan African colonial heritage on economic growth in a sample of nonindustrial countries. An empirical Solow growth model is specified in a way that allows an examination of whether or not growth in Sub‐Saharan Africa reflects a legacy of extractive colonialization strategies, motivated by a hostile disease environment that resulted in extractive growth‐retarding institutions that persisted after independence. Parameter estimates suggest that the partial effects of extractive institutions engendered by a twentieth century colonial heritage account for approximately 30% of the growth gap between the former colonies in Sub‐Saharan Africa and other nonindustrial countries.     

预期到的与未预期到的财政政策冲击及其宏观影响*

本文根据1999-2014年中国宏观经济季度数据,在动态随机一般均衡模型框架下,考察了预期到的与未预期到的财政政策的宏观经济效应及其传导机制。本文研究发现：第一,预期到的与未预期到的财政政策均具有显著的宏观经济效应,二者合起来可以解释3634%的产出波动、1424%的就业波动和618%的物价波动;第二,与未预期到的财政政策直接影响经济均衡系统不同,预期到的财政政策主要是通过影响经济主体关于未来经济状态的信念来改变经济的均衡配置;第三,财政政策的宏观经济效应不仅取决于所选取的政策类型,而且受公众预期的影响。因此,政府不仅应当根据宏观经济目标理性选择财政政策工具,而且需要合理引导公众预期,以增强财政政策的针对性和有效性。     

FINANCIAL DEVELOPMENT AND MACROECONOMIC VOLATILITY

Using cross‐country panel data over the period 1996–2012, this paper examines the impact of financial development on macroeconomic volatility using GMM estimators. In contrast to the linear relationship identified in many previous studies, we present robust evidence suggesting that the effect of financial development on macroeconomic volatility is nonlinear and U‐shaped. We also investigate the potential differences between developed and developing countries. The results of the paper add new evidence and shed interesting insights into the recent debate on the role of finance in macroeconomic fluctuations.     

The empire strikes back: French‐African trade after independence

This paper studies the effects of foreign influence on trade, focusing on the close relations between France and its former colonies in sub‐Saharan Africa (SSA). It shows that between 1960 and 1989—the golden age of French‐African relations—France exported more to its former SSA colonies than to any comparable countries, while they did not export more to France. This excess of French exports concerned a large variety of products, and particularly luxury goods and products in which France was least competitive. An investigation of the underlying mechanisms shows that migration explains most of this additional trade.
