How do I determine whether a specific government policy change is pro-growth or growth-diminishing for CME purposes?

This is a genuinely difficult analytical question because almost every policy has both pro-growth and growth-diminishing elements. The curriculum provides a framework through its list of pro-growth policy elements, which you can use as a scorecard.

The Five Pro-Growth Policy Elements:

1. Sound fiscal policy — sustainable debt trajectory, disciplined spending
2. Minimal intrusion on the private sector — limited regulation, respect for property rights
3. Competition encouragement — antitrust enforcement, reduced barriers to entry
4. Infrastructure and human capital support — transportation, education, R&D investment
5. Sound tax policy — incentives for investment, minimal distortions

Case Study 1 — US 2017 Tax Cuts and Jobs Act:

• Corporate tax reduction (35% → 21%): Pro-growth — reduces capital cost, encourages investment
• Individual rate cuts: Pro-growth — increases incentive to work and invest
• Increased deficit/debt: Growth-diminishing — crowds out private investment eventually
• Repatriation incentive: Pro-growth — brings overseas cash home for domestic use
• Territorial system: Pro-growth — removes distortion on foreign earnings

Net assessment: Mostly pro-growth in the short-to-medium term, with long-term concerns about fiscal sustainability. An analyst would modestly raise US trend growth assumptions while acknowledging the fiscal risk.

Case Study 2 — Trade Barrier Imposition:

Standard economics says trade barriers:

• Reduce specialization and comparative advantage
• Increase consumer prices
• Invite retaliation that reduces export markets
• Create inefficient domestic production

Net assessment: Clearly growth-diminishing. The question is only about magnitude. A broad 25% tariff across major trading partners could reduce trend growth by 0.2-0.5 percentage points.

Case Study 3 — Ambiguous Example: Minimum Wage Increases:

• Increases incomes for low-wage workers (potentially pro-growth via consumption)
• Reduces employment for low-productivity workers (growth-diminishing)
• Encourages automation investment (mixed effect)
• Can reduce poverty-related social costs (long-term pro-growth)

Net assessment: Empirically ambiguous, sensitive to magnitude and local labor market conditions. Don't adjust trend growth significantly based on moderate changes.

Key Practical Rules:

1. Separate announcement effects from implementation effects — Markets often overreact to announcements. Trend growth responds to actual implementation.

1. Evaluate against the 5-element framework systematically — avoid cherry-picking evidence to support a predetermined view

1. Consider persistence — a policy change that might be reversed by the next administration has smaller trend impact than one likely to persist

1. Account for second-round effects — policies that look pro-growth in isolation may invite offsetting responses (retaliation, regulatory arbitrage, political backlash)

1. Use historical base rates — major pro-growth reforms rarely add more than 0.5% to trend growth; major growth-diminishing shocks rarely subtract more than 0.5-1.0%
