A Class of Solitary and Periodic Wave Structures Related to a Dual‐Mode Benjamin‐Bona‐Mahony Equation in Fluid Flow

International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
This study presents the Benjamin‐Bona‐Mahony equation, a new mathematical model for nonlinear wave propagation in medium with just spatial dispersion. The suggested model only considers spatial derivatives, hence representing pure spatial dispersion, in contrast to the traditional formulation that incorporates mixed space‐time derivatives in its ...

Corporate taxes, leverage, and investment: Evidence from Nazi‐occupied Netherlands

The Economic History Review, Volume 77, Issue 4, Page 1477-1508, November 2024.
Abstract We examine the Netherlands around the Second World War, where the occupying Nazi regime overhauled the country's corporate tax regime and introduced a profit tax of 55 per cent. We estimate that the new tax regime cost investors at least 300 million guilders, an amount equivalent to 5 per cent of Dutch GDP in 1940.
