   Sammanfattning : The thesis consists of five self-contained papers. Paper 1: Social Capital vs Institutions in the Growth Process Is social capital a substitute or a complement to formal institutions for achieving economic growth? Research on the impacts of social capital and formal institutions on economic development have so far mainly emerged as two distinct …elds. LÄS MER

3. 12. Essays on Inflation Expectations, Monetary Policy and Tax Reform

   Författare :Kerstin Westergren; Nils Gottfries; Daria Finocchiaro; Stefan Pitschner; Mirko Wiederholt; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inflation expectations; Rational inattention; Frequency of purchase; Consumers; Monetary policy; Instrumental Variables; Event studies; Entrepreneurs; Wealth inequality; Dual taxation; Tax reform; Economics; Nationalekonomi;

   Sammanfattning : This thesis consists of three self-contained essays.Essay I: Why do consumers’ expenditure patterns matter for their inflation expectations? I propose a model of rational inattention where a consumer trades off paying attention between goods bought more or less frequently. LÄS MER

4. 13. On two methods for identifying dynamic errors-in-variables systems

   Författare :Mei Hong; Torsten Söderström; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

   Sammanfattning : Identification of dynamic errors-in-variables systems, where both inputs and outputs are affected by errors (measurement noises), is a fundamental problem of great interest in many areas, such as process control, econometrics, astronomical data reduction, image processing, etc. This field has received increased attention within several decades.

5. 14. Performance Assessment of Wastewater Treatment Plants : Multi-Objective Analysis Using Plant-Wide Models

   Författare :MAGNUS ARNELL; Ulf Jeppsson; Bengt Carlsson; Hans Bertil Wittgren; Diego Rosso; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; benchmarking; BSM; samrötning; energieffektivitet; växthusgasutsläpp; livscykelanalys; matematisk modellering; avloppsvattenrening; benchmarking; BSM; codigestion; energy efficiency; greenhouse gases; life cycle assessment; mathematical modelling; wastewater treatment; benchmarking;

   Sammanfattning : As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. LÄS MER

7. 15. Local and weighted regression. Bias reduction and model validation

   Författare :Astrid Lundgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Nonlinear systems might be estimated, using local linear models. If the estimation data is corrupted by strongly colored noise the local model will have a bias error. In linear system identification the bias error can be reduced by using instrumentalvariable methods. LÄS MER
