Unlike internal ('functional') forms of flexibility of labour, external ('numerical') forms of flexibility (i.e. high shares of people on temporary contract or a high turnover of personnel) yield substantial savings on a firm's wage bill. Savings on wage bills lead to higher job growth, but do...

In this paper we examine the productivity of indigenous soil and water conservation investments in the Boukombe region in Northwest Benin, using an in-depth survey among 101 farmers on farm inputs, outputs, and SWC investments. We show that positive effects of SWC investments are only observed...

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...

Firms have various ways to cope with external risks. This paper analyzes the risk coping behavior that entails the smoothing of inputs (labor, raw materials, or capital). The theoretical framework shows that, if they face adjustment costs, firms prefer to smooth their inputs, especially if they...

This paper uses firm-level survey data matched with official tax records to estimate the unobserved true sales of formal firms in Mongolia. Taking into account firm-level incentives to comply with taxes and a production function technology linking unobserved true sales with observable firm-level...

In this paper we investigate if the predictions of three different models of capital adjustment costs are consistent with the observed investment patterns among manufacturing firms in five African countries. We document a high frequency of zero investment episodes, which is consistent with both...

Using a panel data set for Zimbabwe which includes firm-specific measures of contractual risk, we show that contractual risk has a major effect on the holding input stocks and, to a lesser extent, the constitution of cash reserves. This is consistent with inventories being a hedge against...

This paper uses the recent Vietnam Household Living Standard Survey 2004 to analyze the determinants and impacts of migration in Vietnam. Most of the previous studies on the determinants and impacts of migration have focused on destination rather than origin areas of migration. This limits our...

We investigate the question of whether firms in Africa's manufacturing sector 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...

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...
