An accommodating macro business environment is one that encourages firms to operate efficiently. Such conditions strengthen incentives for firms to be innovative and to increase productive efficiency. Unconducive macro business environment acts as a negative input to the production process. We use the 2008/09 Liberia¡¯s Small Business Enterprise Survey data to estimate firm level score of unconducive macro business environment using a two parameter Rasch Model. The estimated scores were incorporated in an output-semi-oriented radial Data Envelopment Analysis (DEA) model as undesirable inputs. The DEA model was used to estimate technical efficiency and capacity utilization of each enterprise. Estimated technical efficiency and revenue gap were regressed on all inputs using a Tobit model. The results indicate that increase in unconducive macro business environment decreased capacity utilization. To promote the role of small and medium enterprise in sustainable economic development, Liberia needs to improve enterprise¡¯s access to financial services, increase supply of electricity, and combat corruption by public officials.
