One thing is the metrics and, another, the model that you use to understand the metrics and to make predictions. The problem is that you can make a model to justify whatever you want. "With four parameters I can fit an elephant, and with five I can make him wiggle his trunk." John von Neumann. For instance, metrics tell us that public health system are more efficient, but this is anathema to the "neoliberal mindset" and, therefore, to their models. That's without taking into account the big interests that are passed as sound economics. Just check who finance many of the think tanks that publish economic recommendations. We could also talk about development economics and the recipes sold by the IMF.
