A law of 30 June 1973 extended cost of living indexation to the social pension. The indexation of the federal fuel excise was reintroduced. Inflation accelerated again and there was a return of indexation. Indexation allowance cannot create or increase a loss. In September 1982, the indexation of wages and salaries in the public sector was abolished. There is no provision for indexation with increase in cost of living. A new payments indexation system was enacted by President Arturo Frondizi in 1958. In the 2016 Australian federal budget (Coalition), the indexation freeze was extended to 2020. Robert Shiller has done extensive research on all mentioned aspects of government bond indexation. After indexation, the new balance is rounded down to a whole dollar amount. Even the number of employees have been used in empirical studies on fundamental indexation. Any of these different types of indexation can be reversed (deindexation). When there's a choice of discount or indexation method, the trust manager makes that choice. A given country over a specific time series may have been successful conducting indexation.
