This study examines the effects of high-speed railways (HSRs) on gentrification in Japan from 2000 to 2019, using indicators including land prices and income levels. Using the market access index and instrumental variable strategy, we establish a causal relationship between HSR expansion and gentrification. The results show a 39.38% increase in urban land prices and 6.20% rise in urban income compared to a 21.13% decrease in rural land prices and 3.33% decrease in rural income. Additionally, rur

We review the literature on the motivators of consumers’ purchasing decisions regarding autonomous vehicles (AVs), focusing on environmental awareness, vehicle types, concerns about accidents, and merits. The willingness to buy (WTB) and willingness to pay (WTP) for AVs have been extensively studied. However, it is imperative to broaden the outlook and consolidate the existing knowledge base. Although the WTB and WTP for AVs have been studied, automation-level preferences have been underresearch

Over the past 35 years, the development of high-speed rail (HSR) in Japan has markedly enhanced market access and altered spatial distributional dynamics, thereby transforming the socioeconomic landscape in both urban and rural areas. This study delves into the impact of improved market access on regional disparities, with a particular focus on the shifts in population and economic activity between urban centers and their surrounding peripheral regions. We examine three key hypotheses: (1) HSR i

We explore the long-term impact of railway infrastructure on air pollution by examining Japan’s railway network expansion over a 25-year period. Using Difference-in-Differences, regression analysis with market access, and instrumental variables strategies, we identify a causal link between railway development and improved air quality. Our findings show that railway expansion significantly reduces Suspended Particulate Matter (SPM) by 9.576% to 21.65% and Nitrogen Dioxide ( N O 2 ) by 1.401% to 1
