Bullwhip in a Spanish Shop
Lai, Richard - Volkswirtschaftliche Fakultät, … - 2005
Sebastian de la Fuente is the sixth largest supermarket chain in the Basque region of Spain. It has a novel dataset of 108,605 observations on 3,745 SKUs, collected for almost 2 1/2 years. I find the bullwhip effect in the data: at least 80% of the SKUs have a bigger variance in supplies than...

In pursuit for impeccable veracity
Popov, Sergey V. - Volkswirtschaftliche Fakultät, … - 2011
I study the institution of avoiding to hire one’s school own PhD graduates for assistant professorships. I argue that this institution is necessary to create better incentives for researchers to incorporate new information in studies, facilitating the convergence to asymptotic learning of the...

La simulation économique : expérimentation et apprentissage de la réalité économique
Buda, Rodolphe - Volkswirtschaftliche Fakultät, … - 1998
Economic simulation - as economic pattern simulation use - which is already a useful tool of searchers and managers …, would be a tool of economic teacher. When teacher want explain economic theories, he can't do experiment, hence simulation … would take place experiment. Simulation is an analytical (teacher can study some economic poli- cies) and synthetic (teacher …

Market Exchange Modelling Experiment, Simulation Algorithms, and Theoretical Analysis
Buda, Rodolphe - Volkswirtschaftliche Fakultät, … - 1999
The purpose of this paper is, through a system of software, to analyze some theoretical aggregate models. We suggest to build a disaggregated model to compare its results with these of the aggregated one. The disaggregated model uses an analogical mechanism of the individual behaviors so that a...

The distributive consequuences of machismo: A simulation analysis of intrahousehold allocation
Cuesta, Jose - Volkswirtschaftliche Fakultät, … - 2006
Empirical evidence questions the unitary allocation model of the household that underpins the standard measurement of monetary poverty and inequality. Intra-household gender discrimination has been widely shown to shape expenditure decisions, nutrition status, and human capital accumulation of...

Fast and accurate simulation of differently seasoned loan defaults in a Merton-style framework in discrete time
Varsanyi, Zoltan - Volkswirtschaftliche Fakultät, … - 2008
In this paper I present a method for the simulation of the default of such loans that have two important properties … widely considered in modelling, linking them into one single (simulation) framework might not be that common. However, the … most important merit of this paper is showing a fast and accurate simulation algorithm for the asset values. …

Brand and Quantity Choice Dynamics Under Price Uncertainty
Erdem, Tulin; Imai, Susumu; Keane, Michael - Volkswirtschaftliche Fakultät, … - 2003
We develop a model of household demand for frequently purchased consumer goods that are branded, storable and subject to stochastic price fluctuations. Our framework accounts for how inventories and expectations of future prices affect current period purchase decisions. We estimate our model...
