In Thailand, the Business Sentiment Index (BSI) measures the expectations of entrepreneurs regarding current business performance, orders, employment, production, costs and investment. The survey covers a sample of around 1500 entrepreneurs. The questionnaires are sent out during the last week of the previous month and are compiled by the third week of that given month. For each of the variables measured, the proportion of positive, negative and neutral answers is computed, and the final index is reported as a sum of the positive proportions with half of the neutral proportion. The BEI above 50 indicates that business sentiment has improved and below 50 that has worsened.
