This study investigates changes in income, cost of living, indebtedness and savings among casual-contract (daily wage) construction workers following the recently mandated minimum wage increase. For a group of 847 workers identified from the Bangkok Metropolitan Region using the Quota Sampling technique, results show that the post-mandate increase in the total income is smaller than the increase in the minimum wage. This differential is attributable to the smaller increase in the overtime pay rate and the corresponding reductions in the Employee Benefits and Compensation. However, the mandate did not lead to a rise in cost of living or indebtedness, consistent with the general slow-down in the inflation. Interestingly, the mandate is followed by an increase in savings among the workers.
