In continuous-time stochastic calculus a limit in probability is used to extend the definition of the stochastic integral to the case where the integrand is not square-integrable at the endpoint of the time interval under consideration. When the extension is applied to portfolio strategies,...

An application of the Stokes' theorem is illustrated by solving the two state problem, with inequality constraints, of Dobell and Ho concerning the optimal investment of resources. Whenever applicable, the Stokes' theorem approach seems to be elegant and parsimonious

Zwei wesentliche Perspektiven, Arbeitslosigkeit zu untersuchen, sind die der Gerechtigkeit und die der Effizienz. Unverschuldete Arbeitslosigkeit wird als ungerecht empfunden. Zugleich wird häufig argumentiert, dass Arbeitslosigkeit zu gesellschaftlichen Wohlfahrtseinbußen führt, da Arbeit...

This paper explores the interaction between retirement flexibility and portfolio choice in an overlapping-generations model of a closed economy. Retirement flexibility is often seen as a hedge against capital market risks which justifies more risky asset portfolios. We show, however, that this...
