Staring at Economic Aggregators through Information Lenses [PDF]
arXiv, 2008 It is hard to exaggerate the role of economic aggregators -- functions that summarize numerous and / or heterogeneous data -- in economic models since the early XX$^{th}$ century. In many cases, as witnessed by the pioneering works of Cobb and Douglas, these functions were information quantities tailored to economic theories, i.e.

From tools to theories: The emergence of modern financial economics [PDF]
It is shown that early research in modern financial economics had substantially been driven by the application of the research strategy of economics and the use of newly developed mathematical methods. For this purpose the professionalization of business

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Advanced Energy Materials, EarlyView.Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

The Value of Device Characterization for the Optimization of Organic Solar Cells
Advanced Energy Materials, EarlyView.Using the example of organic photovoltaics (OPV), this study examines whether and when additional measurements can be helpful in process optimization. A virtual laboratory based on real solar cells serves as a benchmark function to compare two different approaches for process optimization, namely black‐box optimization (black circle) and model‐based ...

Applied Economic Perspectives and Policy, EarlyView.Abstract The EU aims to reach 25% of the total agricultural area under organic farming by 2030. Interlinking a farm‐level and agro‐economic market model, we assess impacts of achieving the target either at Member State or aggregated EU level. Results show that flexible budget allocation across Member States would be more cost‐efficient and less ...

Do Zambian farmers manage climate risks?
Applied Economic Perspectives and Policy, EarlyView.Abstract This study investigates production responses to climate risk among farmers in Zambia by combining historical rainfall with nationally representative household data. After identifying the importance of January and February rainfall in maize production, we define these months' historical rainfall variations as the climate risk index.

Advanced Energy and Sustainability Research, EarlyView.The energy transition increases electrical demand, primarily met by renewable sources, potentially raising system costs. In this study, the economic effects of flexible demand on solar integration and generation costs in Italy for 2030 and 2040 are assessed.

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids
Advanced Energy and Sustainability Research, EarlyView.Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.
