Deficit spending means the government spends more than it collects in revenue in a given period, so it must borrow to cover the gap. The typical immediate consequence is taking on debt or activating other financing instruments to fund the shortfall.

Answer to your subparts:

• Lay off workers: not a required consequence of deficit spending.
• Cut taxes: not a required consequence; policy responses can include tax changes, but deficit spending itself does not necessitate tax cuts.
• Take on debt: this is the correct consequence of deficit spending.
• Hire more workers: not a required outcome; some deficit-spending programs aim to increase hiring, but it is not the canonical requirement of deficit spending.

If you’d like, I can summarize how deficit spending fits into Keynesian economics and discuss typical policy trade-offs (debt burden, interest costs, inflation risks) with concise examples.
