Abstract: Over the past century, we have witnessed significant changes in economic circumstances that are interrelated. In this dissertation, I focus on three key aspects of these changes. Chapter 1 examines the effect of computerization on educational attainment. I demonstrate that routine-intensive occupations have increased the share of college graduates more rapidly than abstract-intensive occupations over the last 40 years. Based on this fact, I construct a model that explains that half of the increase in the share of college graduates is due to computerization. Chapter 2 reveals the effect of changes in population growth on TFP (total factor productivity) growth. Using a firm-dynamics model extended to include endogenous growth, I show that a significant portion of the decline in TFP growth is due to the decrease in population growth in the US and Japan. Chapter 3 constructs a model to show the increasing trend of the share of investment in intangible assets. Using this model, I demonstrate that the decline in the relative price of investment goods can account for the increasing share of intangible investment. Overall, this dissertation contributes to our understanding of the complex interplay between technology, demographics, and investment patterns in the modern economy.
