Efficiency Versus Effectiveness in Hospitals: A Dynamic Simulation Approach

Hospitals provide highly sophisticated services, but they are largely

The design of management models in hospitals and public organizations at large shows a bend toward reductionism. The reductionism of these models is rooted in their short-termism, and in the...

Communication and attention dynamics: An attention-based view of strategic change

The attention-based view (ABV) has highlighted the role of organizational attention in strategic decision making and adaptation.

In addition, we...

Having grown in real terms by 60% between 2000 to 2008, extra-EU exports have since stagnated. Stripping out other determinants of EU export growth, the focus here is on the impact of trade distortions imposed by foreign governments since the global economic crisis began.
