We consider a two-dimensional cutting stock problem where stock of different sizes is available, and a set of rectangular items has to be obtained through two-staged guillotine cuts. We propose a heuristic algorithm, based on column generation, which requires as its subproblem the solution of a...

There has been a strong interest in short-time work (STW) schemes during the global financial crisis. Using data for 23 OECD countries for the period 2004 Q1 to 2010 Q4, this paper analyses the quantitative effects of STW programmes on labour market outcomes. Special attention is given to the...

Improving school-to-work transitions and ensuring better career opportunities for youth after labour market entrance are common goals in emerging and advanced economies as they can contribute to raising the productive potential of the economy and to increasing social cohesion. However, the...

Despite the fact that today’s young cohorts are smaller in number and better educated than their older counterparts, high youth unemployment remains a serious problem in many OECD countries. This reflects a variety of factors, including the relatively high proportion of young people leaving...

There is little cross-country comparative evidence on the way labour market institutions shape gross job and worker flows, by and large because comparable data for many countries are scarce. By using a unique harmonised dataset on hirings and separations at the industry-level for a large...

There has been a strong interest in short-time work (STW) schemes during the global financial crisis. Using data for 23 OECD countries for the period 2004 Q1 to 2010 Q4, this paper analyses the quantitative effects of STW programmes on labour market outcomes by exploiting the country and time...

We consider a network design problem that generalizes the hop and diameter constrained Steiner tree problem as follows: Given an edge-weighted undirected graph with two disjoint subsets representing roots and terminals, find a minimum-weight subtree that spans all the roots and terminals so that...
