The Economic History Review, EarlyView.Abstract Financial history is plagued by a visibility trap. Using the Brussels Stock Exchange (1850–1913), we demonstrate that asset illiquidity introduced selection bias, which systematically inflated historical risk premia. Applying a latent return model, we argue that correcting for this illiquidity decreases the equity and corporate bond risk ...

Concentration and convergence: Regional productivity in Türkiye, 1950–2020
The Economic History Review, EarlyView.Abstract This paper presents a comprehensive long‐run analysis of regional productivity convergence in Türkiye using a novel dataset combining newly compiled employment estimates with recent output estimates. The seven‐decade analysis reveals substantial productivity convergence driven by labour reallocation away from agriculture alongside within ...

Connectivity and Selective Rural Migration
International Economic Review, EarlyView.ABSTRACT How does infrastructure shape rural development? Using household panel data from a nationally representative sample of Chinese villages, matched to high‐resolution highway maps, we find that road expansion between 2000 and 2015 operates mainly through reallocation, with less productive farmers scaling down or exiting and more productive ...

Transition zones on the railway track : overview
, 2012 Transition zones between bridges, tunnels, artificial and earth structures, including transitions between ballast and non-ballast permanent way (slab track), are a part of the railway track structure where the abrupt change in the rigidity of the track structure and track settlement occurs between individual transverse profiles, as a result of the ...
