Credit constraints in manufacturing enterprises in Africa

We investigate the question whether firms in the manufacturing sector in Africa are credit constrained. The fact that few firms obtain credit is not sufficient to prove constraints, since certain firms may not have a demand for credit while others may be refused credit as part of profit maximising behaviour by banks. To investigate this question, we use direct evidence on whether firms had a demand of credit and whether their demand was satisfied in the formal credit market, based on panel data on firms in the manufacturing sector from six African countries. More than half the firms in the sample had no demand for credit. Of those firms with a demand for credit, only a quarter obtained a formal sector loan. In line with expectations, our analysis suggests that banks allocate credit on the basis of expected profits. However, controlling for credit demand, outstanding debt is positively related with obtaining further lending while micro or small firms are less likely to get a loan than large firms. The latter effect is strong and present in the regression, despite including several variables typically referred to as explaining why small or ‘informal’ firms do not get credit. The role of outstanding debt is likely to be a reflection of inefficiency in credit markets, while the fact that size matters is consistent with a bias as well, although we cannot totally exclude that they reflect transactions costs on the part of banks. Finally, we could not detect any differences between countries in the effects of these factors in the credit allocation rule, although financial deepening is found to explain most of the country-specific fixed effects, shifting the probability of obtaining credit across the firm distribution.

Investment in Africa's manufacturing sector: A four country panel data analysis

Firm-level data for the manufacturing sector in Africa, presented in this paper, shows very low levels of investment. A positive effect from profits onto investment is identified in a flexible accelerator specification of the investment function controlling for firm fixed effects. There is evidence that this effect is confined to smaller firms. A comparison with other studies shows that, for such firms, the profit effect is much smaller in Africa than in other countries. Reasons for the relative insensitivity of investment to profits in African firms are suggested.firm investment, liquidity constraints, African manufacturing

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.investment, human capital, African manufacturing

Rates of Return on Human and Non-Human Capital in Africa's Manufacturing Sector.

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.Risk sharing; labor markets; rent sharing; insurance

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
