In the microfinance sector, experienced lenders enjoy an information advantage over first-time entrepreneurs. Our study proposes an analysis of the business training provided on a par with microloans and its potential effect on borrowers’behavior. First, we present a simple theoretical mechanism showing that an information advantage concerning borrower risk can lead to a non-monotonic relationship between risk and business training provision. Second, using a hand-collected data set of loan applications to a French MFI, we empirically examine the relationship between business training provision and borrower risk, controlling for selection bias and endogeneity. The collected evidence supports the existence of a non-monotonic relationship and shows that business training significantly increases the survival time of loans. Our results are robust to alternative econometric models.

The widely used Oaxaca decomposition applies to linear models. Extending it to commonly used nonlinear models such as duration models is not straightforward. This paper shows that the original decomposition that uses a linear model can also be obtained by an application of the mean value theorem. By extension, this basis provides a means of obtaining a decomposition formula which applies to nonlinear models which are continuous functions. The detailed decomposition of the explained component is expressed in terms of what are usually referred to as marginal effects. Explicit formulae are provided for the decomposition of some nonlinear models commonly used in applied econometrics including binary choice, duration and Box-Cox models.
