Boots' Theory by Pratchett
Rampini elaborates on your idea (and also the Pratchett quote) in his AER article "Financing Durable Assets". See the abstract:


  This  paper  studies  how  the  durability  of  assets  affects    financing.  We  show  that  more  durable  assets  require  larger  down  payments  making them harder to finance, because durability affects the price of assets and hence the overall financing need more than their  collateral value.  Durability  affects  technology  adoption,  the  choice  between  new and used capital, and the rent versus buy decision. Constrained firms invest in less durable assets and buy used assets. More  durable assets  are  more  likely  to  be  rented.  Economies  with  weak  legal  enforcement invest more in less durable, otherwise dominated assets and are net importers of used assets.


Similarly, Orhun and Palazzolo study this argument in "Frugality Is Hard to Afford" in the context of bulk buying large packets at low prices vs. only being able to buy small packets.


  Intertemporal savings strategies, such as bulk buying or accelerating purchase timing to take advantage of a good deal, provide long-term savings in exchange for an increase in immediate spending. Although households with limited financial resources stand to benefit the most from these strategies, they are less likely to make use of them. The authors provide causal evidence that liquidity constraints impede low-income households’ ability to use these strategies, above and beyond the impact of other constraints. Exploiting recurring variation in household liquidity, this study shows that when low-income households have more liquidity, they partially catch up to higher-income households’ ability to use intertemporal savings strategies. The findings provide guidance to marketing managers and researchers regarding targeted promotional design and measurement of deal-proneness. For policy makers, they suggest a new path for decreasing the higher prices low-income households have been documented to pay for everyday goods. Policies have traditionally focused on increasing financial literacy or access to supermarkets. Our work suggests that providing greater liquidity can help low-income households make better use of savings opportunities already available to them.
