Variability in spatial patterns of long nonlinear waves from fast ferries in Tallinn Bay [PDF]
Nonlinear Processes in Geophysics, 2009 High-speed ferries are known to generate wakes with unusually long periods, and occasionally large amplitudes which may serve as a qualitatively new forcing factor in coastal regions that are not exposed to a sea swell. An intrinsic feature of such wakes

Spanish stock returns, growth, and inflation, 1900–2020
The Economic History Review, EarlyView.Abstract This paper studies equity returns in the Madrid Stock Exchange and their connections with the macroeconomy from the emergence of a stock market around 1900 to its ‘big bang’ at the turn of the twenty‐first century. Using high‐quality data from primary sources and the methodology of the modern IBEX35 (published since 1987), we constructed an ...

Between famine and freedom: Food prices during the Indonesian War of Independence, 1945–9
The Economic History Review, EarlyView.Abstract This paper investigates how the Indonesian War of Independence (1945‒9) influenced staple food prices, and how fluctuations in those prices, in turn, shaped the trajectory and dynamics of the conflict. We compiled a dataset comprising more than 8600 prices for staple foods covering the entire Indonesian archipelago from 1939‒49, allowing us to
