“…Although not empirically tested, some scholars contend that in Korea, local governments usually contract out garbage collection for the period of 1–3 years, but when the contract term expires, instead of going through a competitive bidding process, they tend to simply renew the contract, enabling contractors to raise service prices over time (Bae, 2010; Kim, 2010).
