Abstract
The recovery in private business investment globally remains extremely weak more than seven years after the financial crisis. This paper contributes to the ongoing policy debate on the factors behind this weakness by analyzing the role of growth prospects and uncertainty in explaining developments in non-residential private business investment in large advanced economies since the crisis. Augmenting the traditional models of investment with measures of growth expectations for output and uncertainty about global demand improves considerably the ability to explain investment growth. Our results suggest that the main driver behind the weakness in global investment in recent years is primarily a pessimistic outlook on the part of firms regarding the strength of future demand. Lower levels of uncertainty have supported investment growth modestly over 2013–14. Similarly, diminishing credit constraints, lower borrowing costs and relatively stronger corporate profits have also supported the recovery in business investment from 2010 onward. Our findings have two important implications for the global outlook for investment. First, the expected improvements in global growth should support a recovery in investment; however, a slowdown in growth in emerging-market economies or further growth disappointment in advanced economies could restrain this recovery. Second, the ongoing recovery in investment remains vulnerable to uncertainty shocks.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
