   Sammanfattning : This work aims to explore practical one-step-ahead forecasting of structurally changing data, an unstable behaviour, that real-life data connected to human activity often exhibit. This setting can be characterized as monitoring process. LÄS MER

3. 2. Back to a General Theory - An Essay in Persuasion

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Författare :Georg Meier; Petter Svärd; [2017]
   Nyckelord :Keynes; DSGE model; ergodicity; effective demand; tripartite economics;

   Sammanfattning : Many Western countries experience failing monetary policy after the 2008 financial crisis. The lack of alternatives to established rules, even when they appear to fail, motivates a close look at the economic ideas John Maynard Keynes developed in his crisis-ridden lifetime, to answer the question: What can Keynes' writings contribute to the contemporary macroeconomic discussion? We trace from the publication of the General Theory (1936) until our time how macroeconomics has narrowed down into theoretical consensus, elevating policy recommendations developed in moderate times to an exclusive status of optimality.

4. 3. Robust Optimization in Seasonal Planning of Hydro Power Plants

   Master-uppsats, KTH/Optimeringslära och systemteori

   Författare :Daniel Risberg; [2015]
   Nyckelord :Linear decision rules; Hydro power planning; Robust optimization;

   Sammanfattning : Hydro power producers are faced with the task of releasing water from the reservoirs in the right time. To do this there are tools using stochastic optimization that aims at maximizing the income of that producer. The existing methods have a high computing time and grow exponentially with the size of the problem. LÄS MER
