We compared sharing economy development in 90 countries to demonstrate that higher qualities of government are associated with greater sharing economy growth. To explain this finding, we assumed that sharing economy benefits are enjoyed by the public, whereas its costs are chiefly borne by market incumbents. In considering these competing interests, policymakers tend to favor the latter as single-industry interests that can be more easily organized to influence policymaking. We then hypothesized that an electorally competitive, depoliticized, and effective government may tilt the balance against the entrenched market incumbents, leading to the growth of sharing economy industries. Overall, we found some support for this hypothesis. We especially found that electoral competitiveness strongly impacted sharing economy development and that this impact was significantly greater in a country with a depoliticized bureaucracy and effective government.
