In the context of Keynesian economics, which fiscal policy action is most effective in reducing the unemployment rate during a recession?

In Keynesian economics, one of the most effective fiscal policy actions to reduce unemployment during a recession is increasing government spending. When the government spends money, it creates jobs directly by hiring workers for public projects, like building roads or schools. This not only puts money in the hands of those workers but also helps local businesses because these workers will spend their earnings on goods and services. For example, if the government decides to build a new bridge, it will hire construction workers, and those workers will then buy lunch at local restaurants or shop in nearby stores, boosting the economy. Overall, this cycle of spending helps to lower unemployment by stimulating demand for jobs and goods.
