Congestion costs in bottleneck equilibrium with stochastic capacity and demand

Fosgerau, Mogens - Volkswirtschaftliche Fakultät, … - 2008

I analyse congestion costs in the Vickrey bottleneck model of a congestible facility with a peak load in demand. The shape of the peak is endogenous, being the sum of individual scheduling decisions. Capacity and demand are random, which introduces uncertainty into the individual scheduling...

Seasonality, Forecast Extensions and Business Cycle Uncertainty

Proietti, Tommaso - Volkswirtschaftliche Fakultät, … - 2010

Seasonality is one of the most important features of economic time series. The possibility to abstract from seasonality for the assessment of economic conditions is a widely debated issue. In this paper we propose a strategy for assessing the role of seasonal adjustment on business cycle...

Estimation and model selection for left-truncated and right-censored lifetime data with application to electric power transformers analysis

Emura, Takeshi; Shiu, Shau-Kai - Volkswirtschaftliche Fakultät, … - 2014

In lifetime analysis of electric transformers, the maximum likelihood estimation has been proposed with the EM algorithm. However, it is not clear whether the EM algorithm offers a better solution compared to the simpler Newton-Raphson algorithm. In this paper, the first objective is a...

Additive measures of travel time variability

Engelson, Leonid; Fosgerau, Mogens - Volkswirtschaftliche Fakultät, … - 2011

This paper derives a measure of travel time variability for travellers equipped with scheduling preferences defined in terms of time-varying utility rates, and who choose departure time optimally. The corresponding value of travel time variability is a constant that depends only on preference...
