The surprising benefits of a parallel universe


  • Manfredi M.A. La Manna

    (Department of Economics, University of St Andrews, St Andrews, UK)


Suppose that the successful completion of a project requires performing n tasks, each of which has a probability of success p. The paper establishes under what conditions it may be profitable to engage in parallel multi-tasking, i.e. tackling each task by following two independent routes. It is found that for ∀n>1 parallel multi-tasking is profitable for a wide range of parameters when costs are linear and is always profitable for convex costs.
