Different goods, services, programs, or policies are clubbed together in different sectors in the public sector. This leaves lesser options for selection. The bundled stocks of programs/policies may have positive and negative benefits altogether. This leads to economic inefficiency only if there is a poor selection (the total cost of the selection exceeds its total benefits).
For instance, candidates in the assembly elections present an allocation of resources as a party's agenda to gather votes. The allocation includes different programs and policies in certain combinations, which could be beneficial for some and bad for others. The public must agree on one out of the limited choices to choose their next representative.
Economic inefficiency arises when the selected bundle (or representative) creates losses in terms of certain policies. This cannot be ignored as the limited bundles offer both good and bad options together in the same bundle.
Thus, the legislation and the public have to accept that stock which has a greater net positive effect. However, it will include the negative impacts as well, creating economic inefficiency.
