The study looked at how raising the minimum wage in Indonesia in the 1990s affected wages and jobs. They found that the wage increase led to a small rise in average wages (around 5-15%) and a slight decrease in urban job opportunities (0-5%). The impact on jobs varied depending on the size of the company: small businesses saw a drop in employment, while some larger companies actually hired more workers. Overall, employees in these larger companies benefited the most from the minimum wage increase.
