Chasing the perfida Albione: Anglo‐Italian productivity gap in the late 1930s
The Economic History Review, EarlyView.Abstract This paper presents new estimates of Anglo‐Italian labour productivity levels in manufacturing in the late 1930s, derived using the standard single‐deflation approach. The findings confirm a substantial productivity gap between Italy and the United Kingdom at the aggregate level, alongside pronounced intersectoral heterogeneity.

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

The Labor Market Effects of Occupational Licensing in the Public Sector
Industrial Relations: A Journal of Economy and Society, EarlyView.ABSTRACT In the United States, occupational licensing is about twice as prevalent in the public sector as in the private sector. However, the influence of occupational regulation for public sector workers and how it compares with that of private sector workers has not been analyzed in detail.

Standing on a common ground: a comparison of static stability approaches for pallet loading
International Transactions in Operational Research, EarlyView.Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...
