Hello, and welcome to paper-to-podcast.
Today, we're diving into a riveting tale about how schools in New Jersey banded together like a superhero squad to tackle the villain of high internet costs—and won! The academic paper we're discussing, titled "Bundling Demand in K-12 Broadband Procurement" by Gaurab Aryal and colleagues, published on the 13th of February, 2024, reads more like an economic thriller than a scholarly article.
So, sit back and buckle up as we explore how New Jersey schools managed to slash their internet bills while supercharging their broadband speeds. It's a story of cunning strategy, collective bargaining, and, most importantly, how to save a buck or two hundred thousand.
Imagine this: A group of schools walks into an internet service provider's office and says, "We want lightning-fast internet, but we're only going to pay two-thirds of the price." Sounds like a dream, right? Well, it became a reality. After these schools switched to a group-buying scheme, their internet prices took a nosedive, dropping by a third. It's like Black Friday, but for broadband!
And it's not just about the dollars and cents. The speed! Oh, the speed. We're not talking about a tortoise to hare transformation here; we're talking a snail to a space rocket! The schools' download speeds shot up from a sluggish 100 megabits per second to an eye-watering 600 megabits per second. At that speed, you could stream every cat video on the internet simultaneously, and still have bandwidth to spare for a little online learning.
Now, how did Aryal and colleagues unravel this miraculous metamorphosis? They used a method known as an event study approach and a difference-in-differences strategy, which is not a trendy new dance move, but a way to compare schools in the "group-buying club" to those that weren't invited to the party, both before and after the deal went down.
To ensure their results were as sturdy as a sumo wrestler in a yoga pose, the researchers applied a robust bounding approach. This way, they could see if their findings stood up even when assuming the schools' trends were like comparing apples and oranges.
The research didn't just stop at speeds and savings. They also looked at how happy schools were with their broadband buffet. And guess what? They were over the moon! It's like finding out that your all-you-can-eat restaurant has added all-you-can-eat desserts at no extra cost.
Now, every superhero story has its kryptonite, and this research is no exception. The study assumes that the schools not part of this internet alliance would have trudged along at the same pace as the ones that were, which might not be the case. And since this broadband bonanza was voluntary, maybe only the cool, forward-thinking schools jumped on board, leaving the luddites in the dust.
Despite these potential pitfalls, the benefits are as clear as the "Terms and Conditions" checkbox we all blindly agree to. This research has some serious mojo for policymakers and penny-pinchers alike. It shows that when it comes to buying stuff, there's strength in numbers, and that can lead to big-time savings and efficiency gains.
So what's the moral of our story? When schools team up to buy internet, they can save enough money to make Scrooge McDuck do a double-take, and get speeds that would leave the Flash feeling a bit sluggish. It's a win-win, a high-five, and a group hug all rolled into one.

Supporting Analysis
Imagine a world where schools get together to buy internet service in a mega deal, and by doing so, they save a boatload of cash and zoom into the future with internet speeds faster than a cheetah on a skateboard. That's not a wild fantasy; it's what happened in New Jersey! After switching to this group-buying scheme, the schools saw their internet prices plunge by a third. That's like going to the store expecting to pay three bucks for a chocolate bar and only having to fork over two! And hold onto your hats, because their internet didn't just get a little faster—it got six times speedier. We're talking from a sluggish turtle pace of 100 Mbps to a whopping 600 Mbps; that's enough speed to make even tech wizards' heads spin! The cherry on top? The schools saved at least as much moolah as they got from government "E-rate" subsidies. Imagine finding a treasure chest in your backyard that matched what you earned in a year! Plus, under certain assumptions, these schools didn't just save a few pennies; their overall happiness with their internet service shot through the roof. It's like discovering that bundling up on a cold day not only keeps you warm but makes you feel like you're sipping hot cocoa by the fire.
The researchers investigated how bundling the demand for broadband internet for K-12 schools in New Jersey affected prices and speeds. They used an event study approach, specifically a difference-in-differences (DiD) strategy, comparing the outcomes for schools that participated in a demand aggregation initiative to those that didn't, before and after the initiative's implementation. To address potential violations of the parallel trends assumption inherent in DiD analysis, they applied a robust bounding approach. This allowed them to explore how their estimates would change if the trends for participant schools were different from those for non-participant schools. For a deeper understanding of the impact on school welfare, they avoided directly estimating the broadband demand function, which can be complex. Instead, they used a "robust bound approach" to estimate the lower and upper bounds of welfare changes under the assumption that broadband demand functions are log-concave. Overall, their methodology combined empirical auction design analysis with welfare economics and used real-world data from the Educational Services Commission of New Jersey, supplemented by federal data, to examine the impact of procurement design changes on school expenditures and welfare.
The most compelling aspect of this research is its practical application in policy-making and the potential for significant cost savings in K-12 education. The researchers employed a robust methodological framework, including an event study approach and a difference-in-differences strategy to analyze the effects of bundling demand for broadband internet by schools. This approach allowed for a clear comparison between the participant and control groups before and after the intervention, providing credible estimates of the program's impact on internet prices and broadband speeds. The researchers also conducted a sensitivity analysis to assess the robustness of their findings against violations of the parallel trends assumption, which is a best practice in empirical research to strengthen the validity of the conclusions. They used a "robust bound approach" to estimate the welfare impact on schools, which allows for a range of estimates and acknowledges the inherent uncertainty in measuring such effects. By considering both lower and upper bounds for changes in welfare, the research accommodates different assumptions about demand elasticity, adding a layer of rigor to the analysis. Lastly, their methodology leverages a naturally occurring policy change, providing real-world insights into the consequences of procurement design in public-private partnerships. This research stands out for its potential to inform policymakers on how to leverage market design tools to improve public service outcomes efficiently.
One possible limitation of the research is the reliance on the assumption of parallel trends for the difference-in-differences approach. If this assumption does not hold—that is, if the trends for the treatment and control groups were not on the same trajectory prior to the intervention—it can lead to biased estimates of the treatment effect. The voluntary nature of school participation in the consortium could introduce selection bias, as schools with certain characteristics may have been more likely to participate. Additionally, the study focuses on a single state’s intervention, which may limit the generalizability of the results to other regions or contexts with different broadband markets and school systems. Furthermore, the study does not directly estimate the demand function for broadband, instead using bounds to infer welfare changes, which may not capture the full complexity of schools’ valuation of broadband services. Lastly, the research uses data only from before and after the intervention without a longer time series, which may not fully account for longer-term effects or trends.
The research has potential applications in several areas, most notably in public policy and economic market design. Policymakers could use the insights from this study to improve the procurement processes for public services, leading to cost savings and increased efficiency. Specifically, bundling demand, as shown with K-12 broadband internet procurement, could be applied to other sectors where public entities like schools, hospitals, or municipal services procure goods or services. The study could also inform decisions about subsidy programs. Understanding that demand bundling could yield significant savings could lead to a reevaluation of existing subsidy programs, like the E-rate program analyzed in this study. In the realm of market design, this research could influence how auctions and competitive bidding processes are structured, encouraging the consideration of demand bundling to reduce prices and boost competition. The findings may guide the structuring of contracts and bids to take advantage of economies of scale and scope. Additionally, the research might inspire private sector companies that work on large-scale procurement or supply chain management to consider similar bundling strategies to harness efficiencies and negotiate better terms with suppliers.
