Firm size, credit scoring accuracy and banks' production of soft information

Research on SME bank financing generally assumes that smaller firms are more opaque from a lender’s perspective. We propose that the discriminatory power of credit scoring models can be thought of as a proxy for firm opaqueness, given that when these models perform poorly, lenders must invest in the production of ‘soft information’ to supplement the financial data used in these models. Measuring the discriminatory power of probit default models across quintiles of the Irish SME size distribution, we show that our proxy for firm opaqueness increases monotonically as firms get smaller. This finding supports an assumption that is the starting point to a wide strand of literature on SME bank financing. Our findings can also be interpreted as providing an insight to the literature on the determinants of banks’ choice of lending technology. While smaller banks may, as found in a substantial previous literature, produce larger amounts of ‘soft information’ due to their organizational advantages, they may also do so out of necessity: hard-information-based default modelling is less effective among smaller firms, thereby forcing banks that lend to these borrowers to invest more in relationship banking technologies to retain competitiveness.

Hyperinflation in Zimbabwe: money demand, seigniorage and aid shocks

ABSTRACT Zimbabwe experienced record hyperinflation of 80 billion per cent per month in 2008. This article uses new data from Zimbabwe to investigate money demand under hyperinflation using an autoregressive distributed-lag model for the period 1980–2008. The results produce plausible convergence rates and long-run elasticities, indicating that real-money balances are cointegrated with the inflation rate and signifying an equilibrium relationship between the two series. Evidence is also presented suggesting prices were driven by increases in the money supply rather than by changes in price setting behaviour. The article uses the estimated elasticity on the inflation variable to calculate the maximum level of seigniorage revenue that could be raised in the economy. Actual seigniorage levels increased dramatically after 2000, with inflation eventually exceeding the rate required to maximize this revenue stream. This is discussed in relation to international financing constraints and the collapse of the domestic tax base.

Return Migration, Self-selection and Entrepreneurship†

Are return migrants more entrepreneurial? Existing literature has not addressed how estimating the impact of return migration on entrepreneurship is affected by double unobservable migrant self-selection, both at the initial outward migration and at the final inward return migration stages. This paper exploits exogenous variation provided by the civil war and the incidence of agricultural plagues in Mozambique, as well as social unrest and other shocks in migrant destination countries. The results lend support to overall negative unobservable return migrant self-selection, which results in an under-estimation of the effects of return migration on entrepreneurial outcomes when using a ‘naive’ estimator that does not control for self-selection at both the initial migration and at the final return migration stages.
