This week in research #75

Here's what caught my eye in research over the past week:

• Gavresi, Litina, and Tsiachtsiras (open access) look at how motorway and railroad length impacts interpersonal and political trust, and find that infrastructure enhances trust by promoting mobility and exposure to new people and ideas, as well as by elevating political trust as the government is perceived as more reliable and effective
• Arai and Okazawa (open access) find that being the first contestant is favourable in a Japanese television comedy show
• Adamson and Fitzsimmons (open access) construct and analyse a database of warfare around the Mediterranean from 600 to 30 BCE, and find that there was no democratic peace among Ancient Greek city-states and mixed results, both inside and outside of Greece, about how war relates to state power
• Zhou et al. review the last 17 years of research on the impact of artificial intelligence on the labour market
