What have we learned from a decade of manufacturing enterprise surveys in Africa ?

In the early 1990s the World Bank launched the Regional Program on Enterprise Development in several African countries, a key component of which was the collection of manufacturing firm-level data. In this paper the authors review the research based on the data sets generated by these and subsequent firm surveys in Africa, with a special view to what they think are the most important policy implications. The authors survey the research on the African business environment, focusing on market size, risk, access to credit, labor, and infrastructure. They cover the research on how firms choose to organize themselves and how firms do business. They review the research on firm performance, including firm growth, investment and technology acquisition, and exports. They conclude with an extended discussion of the policy lessons.Economic Theory&Research,Private Participation in Infrastructure,Labor Markets,Microfinance,Small Scale Enterprise

Skills, investment and exports from manufacturing firms in Africa.

It has been argued that Africa will not be able to export manufactures as it lacks the necessary skills. Without an ability to export there will only be an incentive to invest in the sector if domestic demand grows rapidly. Comparative data for four African countries - the Cameroon, Ghana, Kenya and Zimbabwe - shows that in the early 1990s investment in manufacturing remained very low. The micro evidence on manufacturing exports is wholly consistent with the macro in suggesting these are, for most African countries, negligible. An exception is Zimbabwe. The paper uses a longer time series from Ghana to ask how skills have impacted on manufacturing investment and exports in the 1990s. Two dimensions of skills are defined and measured. The first is that observable in the education and experience of the workforce. The second is the underlying efficiency with which the firm operates. The latter is shown to be a significant determinant of both investment and exports. These exports are relatively capital intensive; unskilled labour intensive exports remain negligible. Possible reasons for these outcomes are discussed.African

Market integration and structural transformation in a poor rural economy

By developing a simple theoretical model of the impact of market integration on sectoral output and employment in a poor rural setting, this paper demonstrates that trade can induce asymmetric growth. Under certain, plausible, assumptions, the non-farm sector will grow much faster than the agricultural sector when markets become integrated. Promoting market integration may thus be an effective way of encouraging diversification beyond agriculture and catalysing structural change in poor rural economies.Food&Beverage Industry,Economic Theory&Research,Rural Poverty Reduction,Food Security

Network Proximity and Business Practices in African Manufcaturing

We document empirical patterns of correlation in the adoption of technological innovation and contractural practices among manfacturing firms in Ethiopia and Sudan. The analysis is based upon network data indicating whether any two firms in our sample do business with each other, whether they buy inputs from a common supplier and whether they sell output to a common client. We only find limited support for the commonly held idea that firms that are more proximate in a network sense are more likely to adopt similar practices. For certain practices, adoption decisions appear instead to be local strategic substitutes: if ones firms in a given location is using a certain practice, others nearby are less likely to do so. These results appear out of tune with policy discussion of how the economic performance of African's manufcaturing sector can be improved.

Mind the gap ? a rural-urban comparison of manufacturing firms

This paper compares and contrasts the performance of rural and urban manufacturing firms in Ethiopia to assess the impact of market integration and the investment climate on firm performance. Rural firms are shown to operate in isolated markets, have poor access to infrastructure and a substantial degree of market power, whereas urban firms operate in better integrated and more competitive markets, where they have much better access to inputs. Fragmentation may also help explain why urban firms are much larger, much more capital intensive and why they produce much more output per worker. Capital intensity and labor productivity are strongly correlated with firm size. Manufacturing technology choice does not vary strongly across space and increasing returns to scale are modest at best, suggesting that rural-urban differences in output per worker are predominantly driven by differences in capital intensity and Total Factor Productivity (TFP). The average TFP of firms in rural towns is much higher than that of rural firms in remote areas, but small firms in rural towns are not significantly less productive than small firms in other urban areas. A key finding of the paper is that market fragmentation and investment climate constraints impair the growth of the rural non-farm sector. Whereas urban firms exhibit a healthy dynamism, rural firms are stagnant and lack incentives to invest. Paradoxically, limited local demand due to market fragmentation is the most pressing constraint for rural firms, even though they face more severe supply-side constraints than urban firms. Promoting market towns in Ethiopia might be an effective means of capitalizing on the gains from market integration.Access to Finance,Microfinance,Economic Theory&Research,,Debt Markets

Nonfarm microenterprise performance and the investment climate : evidence from rural Ethiopia

This paper uses uniquely matched household, enterprise and community survey data from four major regions in rural Ethiopia to characterize the performance, constraints and opportunities of nonfarm enterprises. The nonfarm enterprise sector is sizeable, particularly important for women, and plays an important role during the low season for agriculture, when alternative job opportunities are limited. Returns to nonfarm enterprise employment are low on average and especially so for female-headed enterprises. Women nevertheless have much higher participation rates than men, which attest to their marginalized position in the labor market. Most enterprises are very small and rely almost exclusively on household members to provide the required labor inputs. Few firms add to their capital stock or increase their labor inputs after startup. Local fluctuations in predicted crop performance affect the performance of nonfarm enterprises, becauseof the predominant role played by the agricultural sector. Enterprise performance is also affected by the localized nature of sales and limited market integration for nonfarm enterprises. The policy implications of these and other findings are discussed.Access to Finance,,Microfinance,Economic Theory&Research,Debt Markets

On the duration of civil war

The authors model the duration of large-scale, violent civil conflicts, applying hazard functions to a comprehensive data set on such conflicts for the period 1960-99. They find that the duration of conflicts is determined by a substantially different set of variables than those that determine their initiation. The duration of conflict increases substantially if the society is composed of a few large ethnic groups, if there is extensive forest cover, and if the conflict has commenced since 1980. None of these factors affects the initiation of conflict. The authors also find that neither the duration nor the initiation of conflict is affected by initial inequality or political repression. This finding is consistent with the hypothesis that rebellions are initiated where they are viable during conflict, regardless of the prospects of attaining post-conflict goals, and that they persist unless circumstances change.Statistical&Mathematical Sciences,Peace&Peacekeeping,Post Conflict Reconstruction,Services&Transfers to Poor,Education and Society,Social Conflict and Violence,Peace&Peacekeeping,Post Conflict Reconstruction,Rural Poverty Reduction,Services&Transfers to Poor

Gradual Trade Liberalization and Firm Performance in Ethiopia

We use firm-level data for the Ethiopian manufacturing sector matched with commodity- level data on tariffs to examine the effect of trade liberalization on firm performance during the 1997-2005 period. We find relatively large positive effects of tariff reductions on total factor productivity, a result that is robust to treating tariffs as endogenous, and to various generalizations of the baseline model. This affects is primarily driven by mechanisms operating at high tariff level, suggesting that excessive tariff levels may be particularly distortionary. We find some evidence that the reduction of tariffs has resulted in smaller and more capital-intensive domestic firms. We note that these effects are consistent with the hypothesis that the trade liberalization has increased competition in the domestic market. We find no significant effect of the trade liberalization on entry or exit rates.

Do African manufacturing firms learn from exporting?

In this paper, we use firm-level panel data for the manufacturing sector in four African countries to estimate the effect of exporting on efficiency. Estimating simultaneously a production function and an export regression that control for unobserved firm effects, we find both significant efficiency gains from exporting, supporting the learning- byexporting hypothesis, and evidence for self-selection of more efficient firms into exporting. The evidence of learning-by-exporting suggests that Africa has much to gain from orientating its manufacturing sector towards exporting.

Contract Flexibility and Dispute Resolution in African Manufacturing

This paper examines the contractual practices of African manufacturing firms using survey data collected in Burundi, Cameroon, Côte d’Ivoire, Kenya, Zambia, and Zimbabwe. Descriptive statistics and econometric results are presented. They show that contractual flexibility is pervasive and that relational contracting is the norm between manufacturers, their suppliers, and their clients. The existence of long-term relations between firms helps them deal with contract non-performance through negotiation. Confrontational methods such as lawyers and courts are used only by large firms and when negotiations fail. Whenever confrontation can be avoided, business is resumed. Of the six studied countries, incidence of breach and the use of lawyers and courts are highest in Zimbabwe which is also the country with legal institutions that best support business. Our favored interpretation is that good legal institutions incite firms to take more chances, thereby encouraging trade and leading to more cases of breach and more recourse to courts and lawyers. A high frequency of contract non-compliance should thus not be interpreted as a sign of imperfect legal institutions.
