Private money and money market integration: The role of payments infrastructure in nineteenth‐century Switzerland

The Economic History Review, EarlyView.
Abstract Using newly collected discount rate data for six Swiss cities from 1846 to 1893, we find no evidence of increasing integration during a 30‐year period of lightly regulated free banking. We attribute this to two structural issues: banks had incentives to ward off competitors by protecting their local monopolies or forming cartels, and there was

Risk premia reconsidered: Illiquidity and selection bias for stocks and corporate bonds in the pre‐First World War period

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 ...

Early Outer Hair Cell Dysfunction Associated With Educational Noise Exposure in Dental Students: Implications for Hearing Conservation in Dental Education

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Dental education involves continuous exposure to high‐frequency noise from clinical instruments, which may cause early outer hair cell damage even before professional practice begins. While noise‐induced hearing loss (NIHL) is a recognised occupational hazard among dentists, evidence regarding subclinical outer hair cell changes ...

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 ...

Rational Expectations Fools' Bubbles

International Economic Review, EarlyView.
ABSTRACT We develop a rational, Walrasian model of speculative bubbles inspired by the Kindleberger–Minsky view, which describes bubbles as wave‐like market processes. Touched off by an initial shock, price booms are initially self‐reinforcing but become self‐destructive later when prices surpass fundamental value.
