Pre-registration
In a long-run cross-country panel 1960-2019, economies with persistently high gross domestic savings rates (Germany, Japan, Switzerland, Korea, Taiwan, Singapore) generate more TFP growth per unit of investment than economies whose investment is predominantly financed by foreign credit inflows or domestic credit expansion. The Austrian-Hayekian prediction is that genuine savings represent forgone present consumption and therefore signal authentic inter-temporal preferences, while credit-financed investment is prone to malinvestment because the underlying inter-temporal price signal (the loan rate) is distorted. The pre-registered claim is that the cross-country elasticity of TFP growth with respect to savings-financed investment exceeds the elasticity with respect to credit-financed investment by a factor of at least 1.5.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
The hypothesis is falsified if the elasticity-ratio of TFP growth to savings-financed vs credit-financed investment is below 1.5, OR if the savings-financed-investment coefficient is not significantly positive at p<0.05.

Panel-FE regression of 5-year-forward TFP growth on savings-financed investment (proxied by gross capital formation minus current-account deficit) and credit-financed investment (proxied by private-credit growth), plus controls. Wald test on the ratio of the two coefficients. Mainstream growth-economics null treats the source of investment finance as irrelevant — the Modigliani-Miller-style assumption is that capital is fungible. A significant differential coefficient supports the Austrian view.

- Claim: In a long-run cross-country panel 1960-2019, economies with persistently high gross domestic savings rates (Germany, Japan, Switzerland, Korea, Taiwan, Singapore) generate more TFP growth per unit of investment than economies whose investment is predominantly financed by foreign credit inflows or domestic credit expansion.

The pre-registered claim is that the cross-country elasticity of TFP growth with respect to savings-financed investment exceeds the elasticity with respect to credit-financed investment by a factor of at least 1.5.
- Falsification rule: The hypothesis is falsified if the elasticity-ratio of TFP growth to savings-financed vs credit-financed investment is below 1.5, OR if the savings-financed-investment coefficient is not significantly positive at p<0.05.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
Hayek (1931 Prices and Production), Mises (1949 Human Action ch.18-20) on the role of genuine savings in coordinating the inter-temporal capital structure. Modern adjacents: Lucas (1990) "Why doesn't capital flow from rich to poor countries?" — the puzzle the Austrians would say is dissolved once you recognise that not all "investment" is alike.
