Simulating Tail Probabilities in GI/GI.1 Queues and Insurance Risk Processes with Subexponentail Distributions

Boots, Nam Kyoo; Shahabuddin, Perwez - 2001

probabilities andspecial fast simulation techniques like importancesampling, multilevel splitting, etc., have to be used. Though …-taileddistributions, previous fast simulation techniques forqueues with subexponential service times have been confined to theM/GI/1 queue. The …

Standard and Shuffled Halton Sequences in a Mixed Logit Model

Staus, Alexander - 2008

. Simulation methods have been developed to approximate a solution for these integrals. This paper describes the Standard Halton … sequence and a modification of it, the Shuffled Halton sequence. Both are simulation methods which can reduce computational … effort compared to a random sequence. We compare the simulation methods in their coverage of the multi-dimensional area and …

Imputing consumption in the PSID using food demand estimates from the CEX

Blundell, Richard W.; Pistaferri, Luigi; Preston, Ian - 2004

This paper assesses the accuracy of decomposing income risk into permanent and transitory components using income and consumption data. We develop a specific approximation to the optimal consumption growth rule and use Monte Carlo evidence to show that this approximation can provide a robust...

Saving on a Rainy Day, Borrowing for a Rainy Day

Alan, Sule; Crossley, Thomas; Low, Hamish - 2012

The aim of this paper is to understand what a recession means for individual consumers, and to model in a life-cycle framework how individuals respond to recessions. Our focus is on the sharp increase in savings rates that have been observed in the current and recent recessions. We show...

Wann werden Serviceleistungen nachgefragt? Ein Mikrosimulationsmodell alternativer Ladenöffnungszeiten mit Daten der Zeitbudgeterhebung - ServSim

Merz, Joachim; Böhm, Paul; Hanglberger, Dominik; … - 2007

Ziel dieser Studie ist die empirisch fundierte Untersuchung der tageszeitlichen Nachfrage nach Serviceleistungen, also der Nachfrage nach Produkten und vertieft nach Dienstleistungen. Zu diesem Zweck greifen wir auf die mehr als 37.000 Zeittagebücher der nationalen Zeitbudgeterhebung 2001/2002...

Expenditure responses, policy interventions and heterogeneous welfare effects in Hungary during the 2000s

Cseres-Gergely, Zsombor; Molnár, György; Szabó, Tibor - 2017

VAT rates have changed multiple times and to a relatively great extent in Hungary during the past years. We use the resulting price changes in estimating the price- and income-elasticity of households' expenditures. As a novelty, we introduce an interaction term in estimating the demand system...

The Shape of the Loss Curve and the Impact of Long-Range Dependence on Network Performance

Mandjes, Michel; Boots, Nam Kyoo - 2001

Empirical studies showed that many types of network traffic exhibit long-range dependence (LRD),i.e., burstiness on a wide variety of time-scales. Given that traffic streams are indeed endowed withLRD properties, a next question is: what is their impact on network performance? To assess...

Fast Simulation of a Queue fed by a Superposition of Many (Heavy-Tailed) Sources

Boots, Nam Kyoo; Mandjes, Michel - 2001

simulation is too time-consuming, and we have to use fastsimulation techniques instead. Due to the exponential decay (in n …,the change of measure is not constant during the simulation run, which is essentially differentfrom many other studies (usually … indeedimproves considerably over naive simulation. We present some accelerations. Finally, we give shortcomments on the influence of …

Bimodality & the performance of PPML

Prehn, Sören; Brümmer, Bernhard - 2012

There has been an extensive discussion on the applicability of Poisson Pseudo Maximum Likelihood (PPML) to trade. Here, we are going to analyse again the performance of PPML but in the light of a bimodal distribution; in addition, we also explicitly account for excess zeros. Simulations are...
