Which fiscal policy action is most effective in closing a recessionary gap in the short run?

In a recessionary gap, the economy is not producing enough goods and services, leading to high unemployment and low demand. One effective fiscal policy action to close this gap is increasing government spending. When the government spends more money on projects like building roads or schools, it creates jobs and puts money into people’s hands, which encourages them to spend more. For example, if the government invests in a new highway, workers are hired to build it, and these workers will then use their earnings to buy food, clothes, and other goods. This increase in spending helps boost the economy and can quickly reduce the recession's effects.
