Summary: Using data from 42 metropolitan areas across the United States, this study found that regular and active users of ride-hailing services are more likely to own fewer vehicles compared to occasional users. Additionally, there was no significant difference in vehicle ownership between regular and active users.

Summary: We investigate the impact of a firm's ownership on credit rationing and find that state-owned enterprises (SOEs) are 12.22% less likely to experience credit rationing compared to non-SOEs. This finding is robust to different definitions of SOEs and regression methods. Furthermore, the effects of state ownership on credit rationing vary among cities, with SOEs being less likely to be credit rationed in cities with low financial development and high government intervention.

Summary: The study found that parking cost, travel cost, and travel time are important factors influencing vehicle ownership decisions, while monthly payment, car ownership importance, and autonomous vehicle safety perceptions also play significant roles at the consumer level. Consumer-level characteristics have the most prominent effect on vehicle ownership decisions, while trip-level characteristics have a small but measurable impact, with parking cost being the most significant factor.

Summary: Currently, the most common method of controlling weeds in commercial agricultural production system is by applying uniform distribution of chemical herbicide through a sprayer without considering the spatial distribution information of crops and weeds, resulting in excessive chemical herbicides being applied. This study aimed to implement site-specific weed control (SSWC) in a corn field by using unmanned aerial system (UAS) to map the spatial distribution of weeds, creating a prescription map based on the weed distribution map, and spraying the field using the prescription map. With our SSWC approach, we were able to save 26.2% of the acreage from being sprayed with herbicide compared to the current method.

Summary: This study examines the impact of residential relocation on travel behaviors and carbon dioxide emissions. Using data from the Fifth Travel Survey of Beijing Inhabitants and land-use data, a structural equation model is built to explore the effects of various factors on changes in household car carbon dioxide emissions. The study finds that commuting distance, vehicle purchases, family size, and transportation modes have direct effects on carbon emissions, while relocation direction, built environment, and household attributes have indirect effects. Recommendations for reducing carbon emissions from private car travel are also proposed.

Summary: The appearance of a dog can influence how people perceive their personality, and the shape of their head may affect the emotional attributes assigned to them. The study found that dogs with less extreme head shapes were most commonly attributed positive emotions, while dogs with more extreme head shapes were attributed negative emotions. These findings highlight the need for further investigation into the impact of morphology on dog-owner relationships and dog welfare.

Summary: This study found that oil ownership affects welfare and that this effect is influenced by the quality of institutions in the country. In countries with weak institutions, private ownership of oil leads to higher welfare, while in countries with strong institutions, state ownership of oil leads to higher welfare. The results are valuable for oil-rich countries in formulating appropriate policies to maximize the benefits of oil and improve the quality of life for their citizens.

Summary: This study contributes to current research by providing a longitudinal analysis of factors related to vehicle ownership dynamics among older adults. The findings show that factors such as loss of partner or divorce, reduced income, age, and being headed by Hispanics are related to decreased vehicle ownership. Additionally, it is found that female older adults living alone are more likely to live in zero-vehicle households. The study suggests that policymakers should consider providing additional support, such as alternative transportation modes, for older adults when owning and using vehicles is temporarily or permanently impossible.

Summary: Decarbonizing commercial vehicles is crucial for China's carbon neutrality target, but the adoption barriers of alternative fuel technologies have been mainly limited to tangible costs. This study introduces a perceived cost of ownership model and finds that alternative fuel technologies have higher costs compared to traditional powertrains, but can still be cost-effective in specific scenarios.

Summary: This paper investigates the positioning strategies of duopoly firms with overlapping ownership. It finds that firms tend to position further apart to soften competition as the degree of overlapping ownership increases, leading to increased profits but reduced consumer and total welfare. The anticompetitive effect of overlapping ownership is exacerbated with additional choices in product positioning.
