Title: Structural Change in Production Networks and Economic Growth
11:00〜12:00
Abstract:We study structural change in production networks for intermediate inputs (input-output network) and new capital (investment network). For each network, we document that the share of output produced by goods sectors has declined since the 1950s, offset by a rising fraction of production by services sectors. We develop a multi-sector growth model to study these trends and show that our framework admits an aggregate balanced growth path with such structural change. Calibrating the model using disaggregated expenditure-side price data for the United States, we find that inputs to intermediates production are complements. However, in contrast to existing literature, we find that inputs to investment production are substitutes. Hence, structural change in production networks implies that resources endogenously reallocate to the slowest growing intermediates producers and the fastest growing investment producers. As a result, we show that investment-specific technical change accounts for an increasing share of U.S. aggregate growth, rising from 30-40% of growth prior to the 1980s to more than 70% since the year 2000. In addition, more than 20% of aggregate growth after 2000 stems from endogenous reallocation induced by structural change. At the same time, productivity growth within the input-output network has stagnated, accounting for the bulk of the recent slowdown in aggregate growth.

要旨:This study examines the impacts of eliminating school zones, focusing on the commuting behavior of high school students. To address this issue, we exploit the reform of the education system of public high schools in Nagasaki City, Japan. Before the reform in 2002, the local government assigned students to equalize the educational level among schools. While the reform enabled the students to choose a school on their own, the gap in academic performance among schools has widened. We found that one possible reason for this gap is the concentration of students from highly educated areas to schools with location advantages regarding transport accessibility and urban amenities.
