That is a 2013 paper by Adilov, Alexander, and Cunningham, here is the abstract:

Space debris, an externality generated by expended launch vehicles and damaged satellites, reduces the expected value of space activities by increasing the probability of damaging existing satellites or other space vehicles. Unlike terrestrial pollution, debris created in the production process interacts with firms’ final products, and is, moreover, self-propagating. Collisions between debris or extant satellites creates additional debris. We construct an economic model to explore private incentives to launch satellites and to mitigate space debris. The model predicts that, relative to the social optimum, firms launch too many satellites and under-invest in debris mitigation technologies. We discuss remediation strategies and policies, and calculate a socially optimal Pigovian tax.

While we are on this topic, I very much liked the movie Gravity, which although it has some dialogue hearkens back to the silent classics of the past. It has spectacular visuals, a “great stagnation” element, a don’t try to be Icarus, live in the mud, and be reborn and baptized in the water element, a reinterpretation of The Book of Job, and a “who builds the best infrastructure anyway?” theme. On top of all that, it is subtle running commentary on the 1969 film *Marooned* and how much the world has, and hasn’t, changed since then.
