Alban William Housego Phillips (1914-75)

3 key takeaways

• A.W. Phillips is best known for the Phillips curve, showing the inverse relationship between unemployment and inflation.
• His work demonstrated a trade-off between unemployment and inflation, impacting economic policy.
• Phillips contributed to dynamic models in economics, enhancing the understanding of economic fluctuations and policy impacts.

Who was A.W. Phillips?

Alban William Housego Phillips was born on November 18, 1914, in Te Rehunga, New Zealand, and passed away on March 4, 1975. He was an influential economist whose work has had a lasting impact on macroeconomic theory and policy.

Phillips initially trained as an engineer and served in the Royal Air Force during World War II before turning to economics. He completed his studies at the London School of Economics (LSE), where he later became a professor.

The Phillips curve

The Phillips curve is A.W. Phillips’s most famous contribution to economics.

In his 1958 paper, “The Relation between Unemployment and the Rate of Change of Money Wage Rates in the United Kingdom, 1861–1957,” Phillips empirically demonstrated an inverse relationship between the rate of unemployment and the rate of wage inflation.

This concept suggested that low unemployment could lead to higher inflation and vice versa. The Phillips curve became a foundational concept in macroeconomics, influencing how policymakers viewed the trade-offs between inflation and unemployment.

Contributions to dynamic models

Beyond the Phillips curve, A.W. Phillips made significant contributions to the development of dynamic models in economics. His work on control theory and economic dynamics helped advance the understanding of how economies evolve over time and respond to various policies.

Phillips’s contributions in this area laid the groundwork for modern dynamic macroeconomic models, which analyze economic fluctuations and the effects of fiscal and monetary policies.

• Control theory: Applied engineering principles to economic modeling.
• Economic dynamics: Advanced understanding of economic evolution and policy responses.
• Modern macroeconomic models: Laid the groundwork for dynamic models used today.

Impact and legacy

A.W. Phillips’s work has left a lasting legacy in economics. Despite evolving debates and modifications over time, the Phillips curve remains a key concept in macroeconomic analysis and policy formulation.

His innovative approach to economic modeling has influenced generations of economists and continues to shape contemporary economic thought. Phillips’s interdisciplinary approach, combining engineering and economics, demonstrated the value of cross-disciplinary insights in advancing economic theory.

Criticisms and evolution of the Phillips curve

While the Phillips curve was initially influential, it has faced criticisms and undergone significant evolution. Economists like Milton Friedman and Edmund Phelps introduced the concept of the natural rate of unemployment and the expectations-augmented Phillips curve, arguing that the trade-off between inflation and unemployment is not stable over time.

The curve’s relevance was further challenged during the stagflation of the 1970s when high inflation and high unemployment occurred simultaneously. Despite these criticisms, the Phillips curve concept continues to be a valuable tool in understanding the complex interactions between inflation and unemployment.
