This volume develops original methods of analyzing biased technological
progress in the theory and empirics of economic growth and income
distribution. Motivated by sharp increases in wage and income
inequalities in the world since the beginning of the new century, many
macroeconomists have begun to realize the importance of biased
technological changes. However, the comprehensive explanations have not
yet appeared. This volume analyzes the effects of factor-biased
technological progress on growth and income distribution and shows that
long-run trends of the capital-income ratio and capital share of income
consistent with Piketty's 2014 empirical results emerge. Incorporating
the modified version of induced innovation theory into the standard
neoclassical growth model, it also explains the long-run fluctuations of
growth and income distribution consistent with the data shown in
Piketty. Introducing a wage-setting function, the neoclassical growth
model is modified to account for unemployment as well as to examine the
dynamics of unemployment and the labor share of income under biased
technological progress. Applying a new econometric method to Japanese
industrial data, the authors test the key assumptions employed and
important results derived in the theoretical part of this book.
