Price Determinants and Depreciation of Used Cars Post-COVID-19
by Ayaan Sundeep Patel
Abstract
Throughout the COVID-19 pandemic, the price of used cars has fluctuated greatly due to numerous factors. Inflation and supply chain issues have been at the forefront of the news and have affected not only cars but most consumer goods. While the majority of society has seemingly progressed past COVID-19, its effects still linger in the used car market, as prices rose 4.6% from January 2023 to February 2023. Therefore, in an effort to study this phenomenon, I scraped data from autotrader.co.uk on February 23, 2023. This study aims to understand the effect of various factors, including mileage, age, and engine size, on various classes of used cars. The five classes being studied are compact cars, luxury sports sedans, luxury mid-size sedans, luxury full-size sedans, and luxury SUVs. A log-linear model is used to model the price determinants of the used cars. A linear model is incorporated to model the depreciation rate of the cars in the dataset. Lastly, this model is used to predict the three-year depreciation rate for each car model, which is then compared to the pre-COVID-19 three-year depreciation rate to see the inflated prices in the UK used car market.

Municipal and Cooperative Internet on Broadband Entry and Competition
by Tianjiu Zuo
Abstract
The broadband market is unique for municipal (government-owned) and cooperative (member-owned) competitors. Their participation, however, raises conflict of interest concerns. Both municipalities and cooperatives are often owners of utility poles that are an essential input for broadband deployment. Internet service providers (ISPs) must lease pole attachment space. While most pole attachment rates are regulated, municipal and cooperative pole owners are exempt by Section 224 of the Telecommunications Act. This paper, therefore, studies the competitive effects of municipal and cooperative ISPs, and the effect of potential entry by municipal and cooperative electric utilities (non-ISPs), on broadband entry and quality. I add to the existing literature by building a dataset of municipal and cooperative non-ISP service areas, designing a method to clean the Federal Communications Commission’s (FCC) broadband data, developing a novel geographic entry threat model, and analyzing municipalities and cooperatives in conjunction. I categorize markets into three types: rural, urban clusters (2,500 to 50,000 people), and urbanized areas (≥ 50,000 people). Looking at Illinois from June 2015 to June 2018, I find that the presence of a municipal ISP lowers the probability of market entry and service quality in urbanized areas. The presence of a cooperative ISP lowers the probability of market entry and service quality in rural areas and urban clusters. The presence of a municipal non-ISP has little to no effect on the probability of market entry or service quality. The presence of a cooperative non-ISP appears to increase the probability of market entry in rural and urbanized areas, but depress service quality in urbanized areas, though these effects could be attributed to bad data.

Competition and Innovation: Evidence from Third-Party Reprocessing in the Medical Device Industry
By Varun Prasad
Healthcare is projected to soon become the industry with the largest amount of spending on research and development in the world. While competition has the potential to catalyze the development of new healthcare technologies and drive down costs, increases in competition have also been thought to hinder innovation as a result of thinner profit margins and reduced incentives. I estimate whether and to what extent competition in the medical device industry promotes innovation. Using Food and Drug Administration data on medical device applications from 1976 to 2019, I examine how original equipment manufacturers respond to the entry of third-party reprocessed devices. I find that, when controlling for year and medical specialty, the introduction of a reprocessed device leads to an almost five-fold increase in new device applications by original manufacturers after both one and two years. These results suggest that an increase in competition within the medical device market has spurred innovation and the development of new technologies.
