The local labour market effects of light rail transit
Many US cities have made large investments in light rail transit in order to improve commuting networks. I analyse the labour market effects of light rail in four US metros. I propose a new instrumental variable to overcome endogeneity in transit station location, enabling causal identification of neighbourhood effects. Light rail stations are found to drastically improve […]
Read MoreTraffic in Honolulu: How to Make Transitory Pandemic Gains Permanent
By Justin Tyndall and Sumner La Croix During the COVID-19 pandemic, Honolulu traffic became much less congested. Local and state governments could help residents keep the social benefits from traffic control by providing incentives to private firms to stagger hours and/or keep more employees working at home. A congestion zone fee to drive within the downtown-to-Waikiki corridor […]
Read MoreCOVID-19 infections, vaccines, and economic recovery
By Carl Bonham, Peter Fuleky, Byron Gangnes, and Justin Tyndall A year ago Hawaii was operating under its first COVID-19 Stay at Home Order. As business activity contracted, the state quickly shed more than 150,000 jobs, and the unemployment rate jumped from 2% to 22%. Today there is hope that the devastation brought by the […]
Read MoreMobility Data Shows Fewer Residents Staying at Home
By Joshua Hu and Justin Tyndall Hawaii has steadily moved forward with its vaccination initiative. Currently, the CDC reports that 26% of Hawai’i residents are fully vaccinated against COVID-19, slightly above the national rate of 24%. Despite progress in vaccinations, during the period from mid-February to early April, Hawai’i has undergone a rise in new […]
Read MoreSea Level Rise and Home Prices: Evidence from Long Island
Global sea level rise is a known consequence of climate change. As predictions of sea level rise have grown in magnitude and certainty, coastal real estate assets face an increasing climate risk. I use a complete data set of repeated home sales from Long Island in New York State to estimate the appreciation discount caused […]
Read MoreThe Impact of Recreational Marijuana Dispensaries on Crime: Evidence from a Lottery Experiment
Many North American jurisdictions have legalized the operation of recreational marijuana dispensaries. A common concern is that dispensaries may contribute to local crime. Identifying the effect of dispensaries on crime is confounded by the spatial endogeneity of dispensary locations. Washington state allocated dispensary licenses through a lottery, providing a natural experiment to estimate the causal […]
Read MoreAre Hawai’i Residents Staying at Home?
By Justin Tyndall and Joshua Hu Staying at home and avoiding crowded spaces is an important way for residents to help contain the spread of COVID-19. Measuring the ability and willingness of Hawai’i’s residents to stay at home is difficult. Having more information on resident movements can help gauge the frequency of in-person interactions and […]
Read MoreCycling mode choice amongst US commuters: The role of climate and topography
Cycling to work is uncommon in most areas of the US, but relatively common in a particular set of metros and neighbourhoods. Explanations for this spatial heterogeneity often focus on differences in local geography, with some areas being allegedly more suitable for cycling. Tyndall estimates the role of topography and climate in determining the share of a metro’s workers who […]
Read MorePedestrian Deaths and Large Vehicles
Abstract: Traffic fatalities in the US have been rising among pedestrians even as they fall among motorists. Contemporaneously, the US has undergone a significant shift in consumer preferences for motor vehicles, with larger Sport Utility Vehicles comprising an increased market share. Larger vehicles may pose a risk to pedestrians, increasing the severity of collisions. I […]
