Historical examples (ISDN, Teletex, telefax, telex) show us that forecasting efforts in the telecommunication sector can go awry - not only by a few percentage points but by large magnitudes. We maintain that with strong network effects it is not possible to forecast the success of...

Standard models of equilibrium unemployment assume exogenous labour market institutions and flexible wage determination. This paper models wage rigidity and collective bargaining endogenously, when workers differ by observable skill and may adopt either individualised or collective wage...

International evidence on the accrual anomaly is sparse and conflicting. Testing for accrual mispricing in 28 equity markets, we provide statistical evidence for anomalous returns in some countries. However, we question whether this result might have occurred by chance alone and that it might...

Using only ordinal axioms, we characterize several multigroup school segregationindices: the Atkinson Indices for the class of school districts with a given fixed numberof ethnic groups and the Mutual Information Index for the class of all districts.Properties of other school segregation indices...
