On the Design and Scalability of Distributed Shared-Memory Databases
(2013)Technical Report. Systems Group, Department of Computer Science, ETH ZurichTo scale-out databases today, partitioning data across several database instances is the common technique. This approach is typically referred to as shared-nothing architecture. In this paper, we propose a new alter- native architecture design for distributed relational databases based on two fundamental principles: We logically decouple query processing and transaction management from data storage and we share data across all query ...Report -
Explosive spalling of concrete in fire
(2013)IBK BerichtA sufficient resistance of concrete structures to fire was always taken for granted. The concrete’s low thermal conductivity ensures an overall good thermal protection of the concrete’s reinforcement, even during longer fire impact. In contrast to ordinary performance concrete used in most structures, the behavior of high (HPC) and ultra-high performance concrete (UHPC) at high temperatures exhibits an increased tendency to explosive ...Report -

Accounting for different uncertainties: Implications for climate investments
(2013)Economics Working Paper SeriesThe paper clarifies the link between changes in risk aversion and the effect on the consumption discount rate. In a general framework that can cope with various forms of uncertainty, it is shown that the response of the consumption discount rate to a change in risk aversion depends on some fundamental properties of the considered uncertainties. The application of this general result to specific forms of uncertainty extends existing results ...Working Paper -

Are Consumer Expectations Theory-Consistent? The Role of Macroeconomic Determinants and Central Bank Communication
(2013)KOF Working PapersUsing the microdata of the Michigan Survey of Consumers, we evaluate whether U.S. consumers form macroeconomic expectations consistent with different economic concepts. We check whether their expectations are in line with the Phillips Curve, the Taylor Rule and the Income Fisher Equation. We observe that 50% of the surveyed population have expectations consistent with the Income Fisher equation and the Taylor Rule, while 25% are in line ...Working Paper -

Optimum growth and carbon policies with lags in the climate system
(2013)Economics Working Paper SeriesWe study the effects of greenhouse gas emissions on optimum growth and environmental policy by using an expansion-in-varieties growth model with polluting non-renewable resources. Climate change harms the capital stock. Our main contribution is to introduce and extensively explore the naturally determined time lag between greenhouse gas emission and the damages due to climate change which proves to be crucial for the transition of the ...Working Paper
