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

This paper examines the macroeconomic consequences of rigidities in the European labour markets, and shows that attempts to impose a single monetary regime on economies with different structures can lead to a breakdown in coordination. Such breakdowns can occur when expenditure-switching effects...

Measures of Active Labor Market Policy are widely used in European countries, but despite many econometric evaluation studies no conclusive cross-country evidence exists regarding "what program works for what target group under what (economic and institutional) circumstances?". This paper...

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...

In this paper we evaluate the forecasting performance of employment expectations for employment growth in 15 European states. Our data cover the period from the first quarter 1998 to the fourth quarter 2012. With in-sample analyses and pseudo out-of-sample exercises, we find that for most of the...

Technological progress and the internet brought about new possibilities of creating, storing, exchanging, replicating, and using various kinds of data for research. This paper discusses some of the dangers embedded into the reuse of data produced by some institutions by other institutions...

In diesem Papier evaluieren wir für 15 europäische Staaten, inwiefern Beschäftigungserwartungen die Prognosegüte des Erwerbstätigenwachstums verbessert. Unser Beobachtungszeitraum beginnt mit dem ersten Quartal 1998 und endet mit dem vierten Quartal 2014. Mit In-Sample- und...

This paper studies theoretically and empirically why and how labor policies may reduce productivity and employment in order to stabilize labor incomes and redistribute resources. It proposes a specific stylized model where the tradeoffs facing labor policies are influenced by structural factors,...
