“…Following the financial crises that many governments experienced in the 1970s, analysts proposed metrics that could be used to measure a government’s fiscal condition and provide an early warning of distress. Fiscal condition indicator systems were described by Groves et al (1981), Clark and Ferguson (1983), and Brown (1993), and despite limitations, including those associated with measuring a complex concept (Hendrick, 2004; Jacob and Hendrick, 2013; Stonecash and McAfee, 1981), and data quality and reporting consistency (Crosby and Robbins, 2013), these indicators are still used (e.g. US Department of Transportation, 2000; Wang et al , 2007; Washington Metropolitan Area Transit Agency, 2016).…”
