Political Corruption - Measuring Corruption

Measuring Corruption

Measuring corruption statistically is difficult if not impossible due to the illicit nature of the transaction and imprecise definitions of corruption. While "corruption" indices first appeared in 1995 with the Corruption Perceptions Index CPI, all of these metrics address different proxies for corruption, such as public perceptions of the extent of the problem.

Transparency International, an anti-corruption NGO, pioneered this field with the CPI, first released in 1995. This work is often credited with breaking a taboo and forcing the issue of corruption into high level development policy discourse. Transparency International currently publishes three measures, updated annually: a CPI (based on aggregating third-party polling of public perceptions of how corrupt different countries are); a Global Corruption Barometer (based on a survey of general public attitudes toward and experience of corruption); and a Bribe Payers Index, looking at the willingness of foreign firms to pay bribes. The Corruption Perceptions Index is the best known of these metrics, though it has drawn much criticism and may be declining in influence.

The World Bank collects a range of data on corruption, including survey responses from over 100,000 firms worldwide and a set of indicators of governance and institutional quality. Moreover, one of the six dimensions of governance measured by the Worldwide Governance Indicators is Control of Corruption, which is defined as "the extent to which power is exercised for private gain, including both petty and grand forms of corruption, as well as 'capture' of the state by elites and private interests." While the definition itself is fairly precise, the data aggregated into the Worldwide Governance Indicators is based on any available polling: questions range from "is corruption a serious problem?" to measures of public access to information, and not consistent across countries. Despite these weaknesses, the global coverage of these datasets has led to their widespread adoption, most notably by the Millennium Challenge Corporation.

In part in response to these criticisms, a second wave of corruption metrics has been created by Global Integrity, the International Budget Partnership, and many lesser known local groups, starting with the Global Integrity Index, first published in 2004. These second wave projects aim not to create awareness, but to create policy change via targeting resources more effectively and creating checklists toward incremental reform. Global Integrity and the International Budget Partnership each dispense with public surveys and instead uses in-country experts to evaluate "the opposite of corruption" – which Global Integrity defines as the public policies that prevent, discourage, or expose corruption. These approaches compliment the first wave, awareness-raising tools by giving governments facing public outcry a checklist which measures concrete steps toward improved governance.

Typical second wave corruption metrics do not offer the worldwide coverage found in first wave projects, and instead focus on localizing information gathered to specific problems and creating deep, "unpackable" content that matches quantitative and qualitative data. Meanwhile, alternative approaches such as the British aid agency's Drivers of Change research skips numbers entirely and favors understanding corruption via political economy analysis of who controls power in a given society.
