The results of ex-post analyses, however, are much more mixed.
The statistical ex-post analyses did not find any of these errors in the model, nevertheless further analysis with more robust methods, e.g. multi-level modelling, is warranted.
However, when it comes to assessments of the long-term sustainability of fiscal policy, such ex-post analyses are not available.
To reduce the risk of false-positive results, Boffetta et al. (2008) suggested that "the strategy for reporting study results should be specified before the results are known and selective reporting or emphasis of statistically significant results based on ex post facto subgroup analyses should be discouraged".
We discuss methods for ex post assessment and analyse assessment issues (unintended intervention effects, interaction effects between different interventions, and assessment impartiality and cost).
Upcoming years will allow first ex-post policy analyses.
By carrying out a hybrid analysis (both simulation and ex-post empirical analyses) of the case of photovoltaic energy in Italy, this article demonstrates that this result cannot be generalised.
If, despite potential unintended consequences, a market intervention is implemented, the plans for ex post assessment should include data collection to ensure that analyses can determine the extent to which such effects will indeed have occurred.
To the best of our knowledge, this is the first study to analyse the influence of insolvency administrators' incentives on the ex post efficiency of a bankruptcy law.
Few recent studies have analysed this topic by using qualitative approaches based on an "ex post" analysis – i.e. after the design and/or the adoption of the AR system - for evaluating the effectiveness of a developed AR application.
This is seen clearly in the laughable analyses published daily in major newspapers, which proudly feature "experts" who explain ex post facto why the market moved in a particular direction.
