Congestion is one of the most challenging issues of urban agglomeration. Congestion costs are higher than socially optimal levels, and more information is needed about the key parameters required to design optimal policies. This paper exploits an exogenous reduction in for-hire vehicle supply in New York City to estimate their effect on travel speed and document substitution patterns to other transportation modes. A 9.1 percent decrease in taxis is associated with increased travel speed by 0.45 min per mile, a 7.2 percent increase. Consumer surplus gains from increased speed fade as waiting times increase and people switch to other transportation modes.
While opioid prescribing rates have fallen since 2012, opioid mortality in the United States (US) climbed to record highs in 2022, per CDC reports. In the last decade, evidence emerged that recreational cannabis legislation (RCL) may help mitigate adverse opioid-related outcomes. Yet, the empirical evidence on the relationship between RCL and opioid misuse as a whole is inconsistent and possibly spurious, given common estimation methods. Studies reporting beneficial associations between RCL and opioid mortality tend to avoid the mechanism of change, often assuming mortality benefits stem from substituting cannabis for opioids. We test this relationship using prescription opioid quantities and access to recreational cannabis in the US state of Oregon. Our approach uses within-state variation in distance to recreational dispensary access generated by RCL and prior volumes of legal opioid use to assess the impact of dispensary access on prescription opioids. Results suggest that communities located closer to recreational dispensaries are associated with lower rates of prescription opioids per capita. We also show that reasonable bounds to our primary specification suggest communities located within a mile from a recreational dispensary have prescription opioid rates per capita that are 1.0–3.9 percent lower than surrounding communities. Despite the reduction, we find no evidence that reducing barriers to cannabis access and subsequent declines in prescription opioids are associated with meaningful changes in opioid mortality.
Using property-level data from 327 larger shopping areas in the Netherlands, we show that the spatial structure of a shopping area resembles a monocentric city in miniature. Just like a monocentric city, a shopping area has a pronounced centre where the rents are the highest and the vacancy the lowest, and a negative retail rent gradient from this centre to the edges. The average retail rent gradient is −17% per 100 m distance, and the vacancy is one and a half times higher at the edge than in the centre. Our model gives insights into how shopping areas respond to downfall in demand, both in the short and long run. Our data, covering the Great Recession, from 2009 to 2012, lend support to these predictions.
This paper investigates the extent of property tax capitalization in the context of a progressive property tax pilot in Shanghai. I utilize a difference-in-differences approach by comparing neighborhoods with different tax rates before and after the implementation of the property taxes. Neighborhoods with a 0.2 percentage point higher marginal property tax rate experience a roughly 2.73% decrease in housing prices relative to their counterparts. The result reflects that at least 71% of expected property tax liabilities are capitalized into housing prices in a year. These changes also imply a large wealth redistribution as large as 2.68 years of average disposable income across homeowners.
We analyze whether the benefits of work experience that was acquired in denser locations can be explained by the quality of jobs that can be found in agglomerations using administrative data on individual employment biographies of workers in Germany. We find that 79% of the premium for work experience gained in the densest regions can be ascribed to the sectors, tasks and establishments in which experience was acquired. Moreover, we find that foreign and native workers, on average, benefit to a similar extent from dynamic agglomeration effects. However, low-skilled foreign workers receive a lower return to experience gained in dense regions than observationally identical natives. This difference can be explained by the fact that the former gain work experience in lower-quality jobs.
This paper studies gender and racial disparities in altruism among social network members who are endogenously linked. We specify group (gender or race) specific altruistic interactions models, as well as intra- and inter-group altruistic interactions models, to capture the heterogeneous patterns of altruism associated with the characteristics of two individuals in pairs. We apply the models to the Add Health data to identify altruism and social interaction effects on academic achievement and smoking behaviors among adolescents. The results indicate that females are generally more altruistic than males, and whites appear to be the most altruistic racial group. We also find that blacks exhibit spiteful effects towards other black students who are considered to “act white.”
