  1. 21. Enhancing aftermarket demand planning with product-in-use data

    Författare :Joakim Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Big data; Digitalization; Product-in-use.; Forecasting; Demand planning; Aftermarket;

    Sammanfattning : Enhancing aftermarket demand planning with product-in-use data ABSTRACT Aftermarket demand planning, consisting of forecast and known demand, is a critical activity for both the uptime of customers’ products and the supply chain-related costs. Traditional aftermarket forecasting methods use historical demand as the only input to the statistically based forecasts, usually combined with judgmental modifications. LÄS MER

  3. 22. Count data modelling and tourism demand

    Författare :Jörgen Hellström; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Time series; Count data; INARMA; Unit root; Aggregation; Forecasting; Tourism; Truncation; Inflation; Simulated maximum likelihood; Bivariate hurdle model.;

    Sammanfattning : This thesis consists of four papers concerning modelling of count data and tourism demand. For three of the papers the focus is on the integer-valued autoregressive moving average model class (INARMA), and especially on the ENAR(l) model. LÄS MER

  4. 23. Electoral Incentives and Information Content in Macroeconomic Forecasts

    Författare :André Reslow; Mikael Carlsson; Jesper Lindé; Gisle James Natvik; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Brexit; Electoral Cycles; Forecast Evaluation; Forecasting; Imperfect Information; Interest Groups; Political Selection; Voting; Economics; Nationalekonomi;

    Sammanfattning : Essay I (with Davide Cipullo): This essay introduces macroeconomic forecasters as new political agents and suggests that they use their forecasts to influence voting outcomes. The essay develops a probabilistic voting model in which voters do not have complete information about the future economy and rely on professional forecasters when forming beliefs. LÄS MER

  5. 24. Rainfall-Runoff Modelling Using Artificial Neural Networks (ANNs)

    Författare :Aman Mohammad Kalteh; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Self-organizing map; Feed-forward multilayer perceptron; Forecasting; Hydrological modelling; Missing values; Rainfall-runoff modelling; Estimation; Artificial neural networks;

    Sammanfattning : Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. LÄS MER

  7. 25. Essays in Quantitative Macroeconomics

    Författare :Pedro Soares Brinca; Martin Flodén; Ellen McGrattan; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Forecasting; Business Cycle Accounting; Fluctuations; Economics; nationalekonomi;

    Sammanfattning : In the first essay, Distortions in the Neoclassical Growth Model: A Cross Country Analysis, I show that shocks that express themselves as total factor productivity and labor income taxes are comparably more synchronized than shocks that resemble distortions to the ability of allocating resources across time and states of the world. These two shocks are also the most important to model. LÄS MER
