Cover NAIRU, Phillips Curve, Okun's law. ## When to Activate - Analyzing unemployment dynamics (structural, cyclical, frictional) - Estimating the NAIRU and its implications for monetary policy - Applying the Phillips Curve to assess inflation-unemployment trade-offs - Using Okun's Law to relate output gaps to unemployment - Evaluating wage growth dynamics and labor share of income - Assessing labor market tightness and its implications for inflation - Analyzing minimum wage effects on employment and welfare - Evaluating labor market policies (active vs passive measures) - Comparing labor market institutions across countries ## Core Concepts ### Types of Unemployment | Type | Definition | Duration | Policy Response | |------|-----------|----------|----------------| | Frictional | Workers transitioning between jobs; normal search process | Short-term | Improve information, matching platforms | | Structural | Mismatch between worker skills and job requirements | Long-term | Retraining, education, relocation support | | Cyclical | Demand-deficient unemployment during recessions | Varies with cycle | Fiscal/monetary stimulus | | Seasonal | Predictable fluctuations (tourism, agriculture, construction) | Recurring | Seasonal adjustment in data | **Measurement:** ``` Unemployment rate = Unemployed / Labor Force x 100% Labor force = Employed + Unemployed (actively seeking work) Participation rate = Labor Force / Working-age Population x 100% Employment rate = Employed / Working-age Population x 100% Broader measures: U-3: Official unemployment rate (ILO definition) U-6: Includes marginally attached workers and involuntary part-time (better measure of labor market slack) Beveridge Curve: Relationship between vacancy rate and unemployment rate - Outward shift = increased mismatch (structural unemployment rising) - Movement along curve = cyclical changes ``` ### NAIRU (Non-Accelerating Inflation Rate of Unemployment) The unemployment rate consistent with stable inflation. Below NAIRU, inflation accelerates; above NAIRU, inflation decelerates. ``` NAIRU estimation approaches: 1. Phillips Curve estimation: Extract NAIRU as the unemployment rate where inflation is stable (inflation expectations = actual inflation) 2. Kalman filter / state-space models: Estimate time-varying NAIRU 3. Structural models: Based on wage-setting and price-setting equations 4. Reduced-form: HP filter or similar statistical decomposition Typical NAIRU estimates (as of mid-2020s): US: ~4.0-4.5% Eurozone: ~6.5-7.0% Germany: ~3.0-3.5% UK: ~4.0-4.5% Japan: ~2.5-3.0% NAIRU is NOT constant — it shifts due to: - Labor market reforms (flexibility, matching efficiency) - Demographic changes (aging workforce) - Globalization and trade openness - Hysteresis effects (prolonged unemployment raises NAIRU) - Technology and automation ``` **Policy significance:** Central banks use NAIRU estimates to gauge labor market slack and calibrate monetary policy. If unemployment < NAIRU, expect inflationary pressure. Wide uncertainty bands around NAIRU estimates limit its precision as a policy guide. ### Phillips Curve **Original Phillips Curve (1958):** Negative relationship between wage growth and unemployment. **Expectations-Augmented Phillips Curve (Friedman-Phelps):** ``` pi = pi_e - beta * (u - u*) + supply_shock pi = actual inflation pi_e = expected inflation u = actual unemployment rate u* = NAIRU beta = slope parameter (sensitivity of inflation to unemployment gap) supply_shock = cost-push factors (oil prices, exchange rate, etc.) When u < u*: inflation exceeds expectations (economy overheating) When u > u*: inflation falls below expectations (slack in economy) When u = u*: inflation equals expectations (stable) ``` **New Keynesian Phillips Curve:** ``` pi_t = beta * E[pi_t+1] + kappa * x_t pi_t = current inflation E[pi_t+1] = expected future inflation (forward-looking) x_t = output gap (or real marginal cost) kappa = slope (sensitivity to the output gap) Key feature: Forward-looking expectations (rational expectations), not backward-looking (adaptive expectations) ``` **Phillips Curve flattening:** Since the 1990s, the Phillips Curve has appeared flatter in many economies — inflation is less responsive to unemployment changes. Explanations: - Better-anchored inflation expectations - Globalization (global slack matters, not just domestic) - Gig economy and labor market flexibility - Measurement issues (output gap uncertainty) - Non-linear: Curve may steepen at very low unemployment rates ### Okun's Law **Relationship between output gap and unemployment gap:** ``` u - u* = -beta * (Y - Y*) / Y* Typical beta: ~0.4-0.5 for the US → A 1 percentage point increase in unemployment corresponds to roughly 2-2.5% decline in GDP relative to potential Alternative (growth rate form): Change in u = -beta * (g - g*) g = actual GDP growth g* = potential GDP growth (typically ~2% for advanced economies) beta = ~0.4-0.5 → If GDP growth is 1pp below potential, unemployment rises ~0.4-0.5pp ``` **Limitations:** - Relationship varies across countries (labor market flexibility matters) - Asymmetric: Unemployment rises faster in downturns than it falls in recoveries - Structural breaks possible (post-crisis periods may shift the relationship) - Labor hoarding in some countries dampens the response ### Wage Determination **Wage-setting frameworks:** - **Marginal productivity theory:** Wages = marginal product of labor in competitive markets - **Efficiency wages:** Firms pay above market-clearing wages to reduce turnover, increase effort, and attract better workers - **Insider-outsider theory:** Employed workers (insiders) have bargaining power; unemployed (outsiders) cannot underbid them due to hiring/firing costs - **Collective bargaining:** Wages set through negotiations between unions and employers. Wage outcomes depend on union density, bargaining coverage, and coordination **Wage Phillips Curve:** ``` Nominal wage growth = Inflation expectations + Productivity growth - beta * (u - u*) Real wage growth should track productivity growth in equilibrium. If real wages grow faster than productivity → unit labor costs rise → inflationary If real wages grow slower than productivity → labor share of income falls ``` **Labor share of income:** - Labor share = Total compensation / GDP - Declining trend in many advanced economies since the 1980s - Drivers: Globalization, automation, declining union power, superstar firms, capital-biased technical change ### Labor Market Institutions | Institution | Effect on NAIRU | Effect on Resilience | |------------|----------------|---------------------| | Employment protection (strict) | Raises NAIRU (slower adjustment) | Dampens cyclical fluctuations | | Unemployment benefits (generous) | Raises NAIRU (higher reservation wage) | Provides automatic stabilization | | Active labor market policies | Lowers NAIRU (better matching) | Supports reallocation | | Minimum wage (moderate) | Ambiguous (depends on level) | Floor on wages, may reduce inequality | | Collective bargaining (coordinated) | Lowers NAIRU (wage moderation) | Facilitates adjustment | | Flexible contracts (widespread) | Lowers NAIRU (easier hiring) | Increases volatility (dual labor market) | ## Methodology 1. **Labor market slack assessment**: Compare unemployment rate to NAIRU estimate; examine U-6, participation rate, and vacancy-unemployment (Beveridge Curve) data 2. **Phillips Curve estimation**: Estimate the relationship between inflation and unemployment using appropriate specification (expectations-augmented or New Keynesian) 3. **Okun's Law application**: Estimate the output gap implied by unemployment data, or vice versa 4. **Wage dynamics analysis**: Decompose wage growth into productivity, inflation expectations, and labor market tightness components 5. **Policy evaluation**: Assess impact of labor market reforms on NAIRU, employment, and welfare 6. **Cross-country comparison**: Compare labor market outcomes relative to institutional frameworks ## Templates ### Labor Market Dashboard ``` Country: __________ Period: __________ Employment Indicators: Unemployment rate (U-3): ____% (NAIRU estimate: ____%) Unemployment rate (U-6): ____% Labor force participation: ____% Employment rate: ____% Vacancy rate: ____% V/U ratio: _____ Wage Indicators: Nominal wage growth (YoY): ____% Real wage growth (YoY): ____% Productivity growth (YoY): ____% Unit labor cost growth (YoY): ____% Labor share of GDP: ____% Phillips Curve Assessment: Unemployment gap (u - u*): ____% Implied inflation pressure: [ ] Disinflationary [ ] Neutral [ ] Inflationary Okun's Law Implied: Output gap from unemployment: ____% Consistent with GDP growth: ____% ``` ## Quality Gate - [ ] Unemployment decomposed by type (frictional, structural, cyclical) - [ ] NAIRU estimate used with explicit uncertainty range acknowledged - [ ] Phillips Curve specification appropriate (expectations-augmented or NK) - [ ] Phillips Curve flattening considered when interpreting slope estimates - [ ] Okun's Law coefficient appropriate for the country analyzed - [ ] Wage growth decomposed into productivity, expectations, and slack components - [ ] Broader measures of slack considered (U-6, participation, underemployment) - [ ] Labor market institutions accounted for in cross-country comparisons - [ ] Beveridge Curve shifts assessed for structural change in matching efficiency - [ ] Distributional effects of labor market conditions analyzed (by skill, age, region)
