Correlation Between GDP Growth, Inflation, and Unemployment

The heatmap above illustrates the pairwise correlations among GDP Growth (%), Inflation Rate (%), and Unemployment Rate (%) from the Finance & Economics Dataset (2000–2008).

Interpretation

1. Weak Relationships Observed
   The correlations are close to zero, indicating minimal short-term linear association among the three macroeconomic indicators.
   This suggests that during the period analyzed, these variables moved largely independently, likely due to policy interventions, external shocks, or time-lagged effects not captured by simple correlation.

2. GDP and Inflation (–0.02)
   The near-zero correlation implies that higher GDP growth did not consistently coincide with inflationary pressures during this timeframe — a pattern typical of economies experiencing stable but moderate growth cycles.

3. GDP and Unemployment (–0.00)
   While economic theory (Okun’s Law) suggests that higher GDP growth should reduce unemployment, this weak correlation indicates that short-run growth fluctuations did not immediately translate into job creation, possibly due to structural labor market rigidities.

4. Inflation and Unemployment (–0.03)
   A faint negative relationship aligns directionally with the Phillips Curve, where lower unemployment may be associated with rising inflation. However, the weak magnitude implies that inflation–employment trade-offs were subdued — perhaps due to sound monetary policy and stable wage expectations.

Analytical Insight

This correlation matrix highlights that:

• The short-run co-movements among these core indicators are weak.

• Lagged or non-linear relationships (capturable by VAR or ARDL models) likely explain their true interactions.

• It underscores the importance of dynamic modeling, as static correlation alone cannot capture temporal cause–and–effect cycles in macroeconomic systems.

Policy and Research Implications

• Policymakers should rely on multi-equation systems (e.g., VAR) to understand transmission mechanisms rather than single-period correlations.

• Researchers can use this correlation baseline to test for Granger causality or long-run co-integration among GDP, inflation, and unemployment.
