Fiscal policy Study Guide

📖 Core Concepts Fiscal Policy – Government use of taxes and spending to steer the economy. Keynesian Insight – Changing taxes/spending shifts aggregate demand (AD), affecting output and employment. Fiscal vs. Monetary – Fiscal = taxes / spending (government); Monetary = money supply & interest rates (central bank). Stances – Neutral: deficit ≈ historical average; Expansionary: spending > revenue (recession); Contractionary: higher taxes / lower spending (inflation). Lags – Inside lag: time to design & pass legislation; Outside lag: time for the policy’s impact to appear. 📌 Must Remember Expansionary fiscal policy → ↑ AD → higher price level and output (short‑run). Contractionary fiscal policy → ↓ AD → lower inflation & unemployment toward targets. Liquidity trap: interest‑rate cuts fail → monetary policy weak → fiscal stimulus more potent. Crowding‑out: government borrowing can ↑ market rates → ↓ private investment (less in liquidity traps). Net‑export effect: fiscal expansion → currency appreciation → ↓ exports, ↑ imports → ↓ net exports. Balanced‑budget framework may allow temporary deficits/surpluses aligned with the business cycle. 🔄 Key Processes Designing Expansionary Policy Identify recession → propose ↑ government spending (e.g., public works) and/or tax cuts. Estimate financing need → issue Treasury bonds if deficit. Pass legislation (inside lag) → implement projects (outside lag) → monitor AD, output, price level. Implementing Contractionary Policy Detect overheating/inflation → raise tax rates and/or cut discretionary spending. Use surplus or bond repayments to reduce deficit. Observe decline in aggregate income → lower consumer spending → inflation pressures ease. Balancing Budget Over Business Cycle During downturn → allow deficit (stimulus). During expansion → run surplus or neutral stance to avoid overheating. 🔍 Key Comparisons Fiscal Policy vs. Monetary Policy Administration: Government department vs. central bank. Tools: Taxes & spending vs. money supply & interest rates. Speed: Months (monetary) vs. legislative cycles (fiscal). Political pressure: Less for monetary (independent) vs. high for fiscal (election cycles). Expansionary vs. Contractionary Stance Goal: Boost AD & output vs. cool AD & curb inflation. Mechanism: ↑ spending / ↓ taxes vs. ↑ taxes / ↓ spending. Typical timing: Recessions vs. booms. ⚠️ Common Misunderstandings “Fiscal policy always crowds out private investment.” True in normal markets; false in liquidity traps where interest‑rate rise is muted. “Balanced‑budget means never run a deficit.” In practice, cyclical adjustments permit temporary deficits to smooth the business cycle. “Higher government spending always causes inflation.” Inflation occurs only when stimulus uses already‑fully‑employed resources; idle resources absorb the boost without price pressure. 🧠 Mental Models / Intuition AD Shift Model – Visualize fiscal actions as moving the AD curve right (expansion) or left (contraction). Lag Timeline – Inside lag (policy design) → implementation → outside lag (effect). Longer inside lag makes fiscal less reactive than monetary. Crowding‑Out Spectrum – Think of borrowing as a “budget tug”: in tight credit markets it pulls interest rates up (crowding out); in a liquidity trap the tug is slack (minimal crowding out). 🚩 Exceptions & Edge Cases Liquidity Trap – Interest‑rate cuts ineffective; fiscal stimulus can work without causing crowding out. Fully Employed Economy – Stimulus may be inflationary; in a slack economy it mainly raises output. Developing Economies – Fiscal focus on human‑capital investment (infra, education) to promote long‑run growth, not just short‑run demand. 📍 When to Use Which Use Fiscal Expansion when: Deep recession, monetary policy hits zero lower bound or liquidity trap. Need to target specific sectors (infrastructure, education). Use Fiscal Contraction when: Inflationary pressures rise, output near potential, and monetary policy is already tight. Choose Monetary Tools for: Rapid, fine‑tuned adjustments (interest‑rate changes) when political lag is undesirable. 👀 Patterns to Recognize “Spending ↑, Taxes ↓ → AD ↑ → Output ↑, Price ↑” → classic expansionary fingerprint. “Deficit financing + strong demand → currency appreciation → net‑export decline.” “Inside lag long + outside lag short → policy may overshoot (overheat) if economy recovers quickly.” 🗂️ Exam Traps Distractor: “Fiscal policy always works faster than monetary policy.” – Wrong; fiscal suffers longer inside lag. Distractor: “Crowding out eliminates any benefit of fiscal stimulus.” – Incorrect in liquidity trap or when spare capacity exists. Distractor: “Balanced‑budget rule forbids any deficit.” – Misleading; cyclical adjustments are allowed. Distractor: “Higher taxes always reduce inflation.” – Not always; if tax increase coincides with a recession, it may deepen output loss. --- Study tip: Sketch the AD‑AS diagram for each stance, label the lag periods, and note where the liquidity trap changes the usual crowding‑out expectation.
