The Quarterly Business Climate Survey of IEER is based on the survey of 400 CEO respondents about their business situation and expectations. The Quarterly Business Climate Index and the Quarterly Uncertainty Index were calculated from the full sample of 300 small and medium-sized enterprises (20-249 employees) and 100 large companies (250+ employees). For small and medium-sized enterprises, an SME Outlook Business Climate Index and an SME Outlook Uncertainty Index were calculated.
