The measurement of the index is the result of cooperation between the Hendal market research agency and the Croatian business weekly 'Lider'.
Business optimism in Croatia was on the rise in the first three months of 2006, the Hendal executive director, Darko Ivancic, told a news conference in Zagreb on Wednesday.
He explained that this was a moderate rise and that this trend could be expected to continue through the rest of this year.
Ivancic said that businessmen's expectations were also more optimistic than the assessment of the current business situation.
