Is the era of rapid economic growth in high-income countries coming to an end? Did the economic crisis of 2007 signify a turning point in global economies? Or are we on the brink of a new period of growth driven by artificial intelligence? These questions are pivotal in shaping the future of our societies, as economic stagnation often begets contentious politics.
Reflecting on the historical record and the unique opportunities that have shaped economies, the narrative becomes intriguing. Looking specifically at the UK, a country grappling with lackluster dynamism post-World War II, reveals a compelling story of growth. According to the Conference Board, UK real GDP per capita surged by 277% between 1950 and 2023. In comparison, the United States saw a 299% increase, France at 375%, Germany at 501%, and Japan leading the pack with a remarkable 1,220% rise in real GDP per capita.
Despite such impressive growth figures, discontent seems to linger in the air. The root of this malaise might lie in the diminishing growth rates over time. The post-1945 era witnessed remarkable growth, with the US leading the charge, and the subsequent periods showing a gradual decline in growth rates. It is worth noting that the recent years marked the first time the US outpaced France, Germany, Japan, and the UK in both GDP per capita and output per hour growth.
The “miracle” growth post-1945, particularly in Europe and Japan, was a culmination of several unique factors like postwar reconstruction, mass consumption, trade liberalization, and efficient macroeconomic policies. This golden era of growth was a once-in-a-lifetime opportunity. The subsequent slowdown in growth rates post-1970s is indicative of an era where major growth opportunities had been exhausted, and new regions like emerging Asia took the baton of growth.
Emerging technologies, especially those of the digital revolution, continued to push technological boundaries forward. However, scholars like Robert Gordon argue that the overall rate of technological progress has tapered compared to the pre-WWII era. Additionally, the proliferation of labor-intensive services and challenges in increasing productivity further dampened overall productivity growth.
Various temporal boosts in growth have shaped the 20th and early 21st centuries. Factors like rising female labor force participation, extended periods of education, and declining dependency ratios offered transient growth spurts. For the UK, EU membership and inflation-driven public debt reduction were vital. Yet, challenges like the financial crisis, pandemic, and consequential rise in public debt underscored the cyclical nature of economic growth.
Moving forward, the old high-income economies face the task of managing higher public spending amidst demographic shifts. Nurturing economic reforms that foster competition, innovation, investment, and encouraging skilled immigration are pivotal. The promise of AI driving productivity growth sustainably without disrupting essential information ecosystems becomes a beacon of hope.
As we navigate through this era of growth deceleration, policymakers must prioritize sustainable growth strategies. Ensuring that growth remains ecologically and politically viable is paramount. The slowdown in growth rates presents a critical policy challenge that demands attention and proactive solutions.
