Knowledge-based Economy in a Historical Perspective: A Statistical Analysis of GDP Growth, Wealth Accumulation and Income Distribution in G7 Countries during 20th and 21st Century

Abstract:

Current study is part of a cycle of publications focusing on Knowledge-based economy [KBE] realized during the past decade by the author focusing both on macroeconomic theory and management methods evolution through the whole 20th and 21st century, on which his PhD dissertation is based. Since former analysis already pointed out, that two different points of view concerning KBE main features exist in the literature, e.g.:

  1. Traditional optimistic KBE interpretation as a phase of development of market economic systems, during which knowledge, human capital and innovation paved the way to unheard economic growth, based mainly on mainstream theory and neoclassical endogenous growth models (Aghion and Howitt, 1992, Galor and Moav, 2004, Harris, 2001, Lucas, 1988, 2004, Ocean Tomo, 2020, OECD, 1995, Sala-i-Martin, 1990a, 1990b, Solow, 1956, 1957, 1988, 2000, Valente, 2016a, 2016b, 2020a, 2025a, 2025b, 2025c, 2025d);
  2. The more in line with heterodox theory, alternative critical, or at least more pessimistic, characterization of current KBE as a particularly unstable phase of development, during which lower economic, growth, more frequent crisis, physical capital accumulation stagnation and sky-rocketing income inequalities increases can be observed in main market economies in comparison to Industrial Era [IE] leading to an increased recurs to more flexible management methods to cope with such KBE negative features (Bhaduri, and Marglin, 1990, Galbraith, 2014, Garegnani, 1978, 1979, 1983, 1992, 2012, Godin, 2006, Homburg, 2014, Kalecki, 1971, 1974, Keynes, 1936, Kunkel, 2014, Lavoie, 2022, Lavoie and Stockhammer, 2012, 2013, Mikuła, 2006, Onaran and Stockhammer, 2001, Pasinetti, 2000, Piketty, 2014, Valente, 2020b, 2021, 2026),
