Selfish routing in congested networks generally does not minimize total system travel time, and as its direct result, traffic equilibrium is typically inefficient. Bounding the inefficiency of selfish routing has become a recent emerging subject of researches by looking into the worst case ratio of the total cost in a deterministic User Equilibrium (UE) point to the total cost of System Optimum...

Abstract The causes of market inefficiency are many. We suggest an additional cause — buyers’ random entry order. In a where identical sellers compete for buyers heterogeneous valuations, first come served is the norm. Since all choose cheapest available good, low-valuation buyer who enters late may find remaining goods unaffordable, which markets not to clear. therefore propose coordination so...

We demonstrate how earlier approaches to model the impact that corporate social responsibility (CSR) has on investment inefficiency are likely be incorrect and propose use of stochastic frontier methodology this relationship. apply approach a sample European listed companies, providing robust evidence CSR performance is negatively associated with inefficiency. This result consistent claim high ...

Abstract This paper accounts for spatial effects by benchmarking farms against their k ‐nearest neighbours (KNN) and measuring inefficiency in a non‐parametric dynamic by‐production setting. The optimal number of which are compared corresponds to the value that maximises Moran I test autocorrelation good bad output farms' two sub‐technologies. scores output, variable inputs, investments outputs...
