Do African Manufacturing Firms Learn from Exporting

We use firm-level panel data for the manufacturing sector in four African countries to investigate whether exporting impacts on efficiency, and whether efficient firms self-select into the export market. Based on simultaneous estimation of a production function and an export regression, our preferred results indicate significant efficiency gains from exporting, which can be interpreted as learning by exporting. We show that modelling unobserved heterogeneity by a flexible approach is important for deriving this conclusion. A policy implication of our results is that Africa would gain from orientating its manufacturing sector towards exporting.

Rates of Return on Physical and Human Capital in Africa's Manufacturing Sector

In this paper two sets of issues are addressed using panel data from the manufacturing sector of five African countries. First, how high are the returns to human relative to physical capital. Second, what is the relative importance of technology and endowments of human and physical capital in determining differences in earnings and productivity across the countries. Evidence from earnings functions shows that the private returns to both experience and education rise with the level of education. Private returns rise from 3 per cent at the primary level, to 10 per cent at the secondary level and 35 per cent for tertiary. Evidence from the production function gives lower returns on education than from the earnings function. Rates of return on physical capital exceed 20 per cent and greatly exceed the average return on human capital. Data is available on the stocks of human and physical capital across the countries. Productivity and earnings differentials are shown to be large between Cameroon and Ghana. These differences are due almost entirely to differences in physical, not human, capital endowments.

Exports of African manufactures: macro policy and firm behaviour

Macro policy has changed the real exchange rates for African countries dramatically in the 1990s. In this paper the possible impact of macroeconomic policy on firms in the manufacturing sector is considered based on a panel survey of such firms in Cameroon. Kenya, Ghana and Zimbabwe. The data show that most large African manufacturing firms do export, but most do not specialize in exporting. An export equation is estimated both for the propensity of the firms to export and the percentage of output exported. It is shown that a stable export function can be estimated for all four countries over the three rounds of the survey. While there is no evidence that real devaluations have effected a general rise in manufactured exports there is evidence from the surveys of a rise in the percentage of output exported from the Cameroon. Reasons for the lack of a general response to macro policy are suggested. In the Cameroon, large firms did increase their propensity to export. Understanding the links between macro policy and firm performance may require an understanding of how such policies impact on different types of firms.

Market access, supplier access, and Africa's manufactured exports: A firm level analysis

Abstract In a large cross-country sample of manufacturing establishments drawn from 188 cities, average exports per establishments are smaller for African firms than for businesses in other regions. Based on the estimation of firm level exporting equations, we show that this is mainly because, on average, African firms face more adverse economic geography and operate in poorer institutional settings. One part of the effect of geography operates through Africas lower ‘foreign market access’: African firms are located further away from wealthier or denser potential export markets. A second occurs through the regions lower ‘supplier access’: African firms face steeper input prices, partly because of their physical distance from cheaper foreign suppliers, and partly because domestic substitutes for importable inputs are more expensive. Africas poorer institutions reduce its manufactured exports directly, as well as indirectly, by lowering foreign market access and supplier access. Both geography and institutions influence average firm level exports significantly more through their effect on the number of exporters than through their impact on how much each exporter sells onto foreign markets.

Risk Sharing in Labour Markets

Empirical work in labour economics has focused on rent sharing as an explanation for the observed correlation in cross-sections between wages and profitability. The alternative explanation of risk sharing between workers and employers has not been tested. Using a unique panel data set for four African countries we find strong evidence of risk sharing. Workers in effect offer insurance to employers: when firms are hit by temporary shocks the effect on profits is cushioned by risk sharing with workers. Rent sharing is a symptom of an inefficient labor market. Risk sharing, however, can be seen as an efficient response to missing markets. Our evidence suggests that risk sharing accounts for a substantial part of the observed effect of shocks on wages.

Fiscal Multipliers Over the Growth Cycle: Evidence from Malaysia

This paper explores the stabilisation properties of fiscal policy in Malaysia using a model incorporating nonlinearities into the dynamic relationship between fiscal policy and real economic activity over the growth cycle. The paper also investigates how output multipliers for government purchases may alter for different components of government spending. The authors find that fiscal policy in Malaysia has become increasingly pro-cyclical over the last 25 years and establish that the size of fiscal multipliers tend to change over the growth cycle. A 1 Malaysian Ringgit rise in government (investment) spending leads to a maximum output multiplier of around 2.7 during growth recessions, and around 2 in normal times. The returns to government spending in Malaysia are greater when the focus is on public investment, as opposed to consumption. Changes in tax policy are less effective in stimulating economic activity than direct government spending. These results provide empirical backing to conjectures in the recent literature implying that procyclicality in fiscal policy reduces the effectiveness of fiscal actions in emerging markets.

Inequality of outcomes and inequality of opportunity in Tanzania

The paper investigates the structure and dynamics of consumption inequality and inequality of opportunity in Tanzania. The analysis covers the period 2001 to 2012. It reveals moderate and declining levels of consumption inequality at the national level, but increasing inequalities between geographic regions. Spatial inequalities are mainly driven by the disparities of households’ characteristics and endowments across geographic locations. An important part of these endowments results from intergenerational transmission of parental background. Father’s education appears as the most important background variable affecting consumption and income in Tanzania. Without appropriate policy actions, there are few chances for the next generations to spring out of the poverty and inequality lived by their parents, engendering risks of poverty and inequality traps in the country.

Economic Geography and Manufacturing Productivity in Africa: Ananalysis of Firm Level Data

We compare samples of textiles and garments producers across groups of countries to find that, in general, productivity is far lower in Sub-Saharan Africa than it is in India. Indian manufacturers in turn are significantly less productive than their counterparts in Morocco, while producers in some SSA countries do match or exceed the Indian standard. The paper assesses the importance of geography as a possible factor in these gaps compared to such possible causes as trade policy and the quality of public institutions. It turns out that both institutions and trade policy are strong influences on country productivity averages. However, geography is also as powerful an influence in as far as it affects access to export markets and to input supplies.

Selection, Firm Turnover, and Productivity Growth: Do Emerging Cities Speed up the Process?

This paper identifies and estimates the impact of firm entry and exit on plant-level productivity in Ethiopia as part of a selection mechanism that might be driving aggregate productivity growth in cities. Specifically, the paper investigates how firms’ entry and exit contribute to the pace of factor reallocation and total factor productivity growth within industries—and whether these processes occur in higher numbers and rates in larger cities. The analysis is carried out using establishment census data from Ethiopia that cover the period from year 2000 to 2010. Importantly, these data include information on plants’ physical outputs and their prices, which allows distinguishing between revenue-based measures of total factor productivity (TFPR) and those based on physical productivity (TFPQ). The analysis reveals that these two measures generate very different results under imperfect competition, suggesting that physical productivity measures (TFPQ) are better suited to examining firm dynamics when local producers have some degree of market power. In addition, the findings show that less productive (higher cost) firms are more likely to exit than their more productive (lower cost) rivals—but the analysis controls for producers’ transport costs. This is consistent with the probability of firm exit being higher when transport costs are lower.

Housing finance and inclusive growth in Africa: benchmarking, determinants, and effects

Using a partially constructed panel database of 48 Sub-Saharan African countries from 2000 to 2013, this paper analyzes the structure of housing finance in Africa, its determinants, and its impact on inclusive growth. The findings show that market capitalization and urbanization are key positive determinants of housing finance, and the post-conflict environment is conductive to greater housing finance development. This result suggests that housing finance is driven by standard market forces of demand and supply. In addition, the analysis finds that housing finance development in Africa is not yet an effective tool for reducing economic inequality, at its current, very early stage. However, the paper shows that above a given threshold, housing finance could be efficient at reducing inequality. Finally, there is a slightly positive relationship between housing finance and greater economic development in Africa. All these findings suggest that policies to boost housing finance development in Africa would be fruitful in the medium to long terms.
