How to meet this need is an open question, but “behavioral insights” are likely components of future policy designs. Applying well-established behavioral insights to low-income house- holds raises questions of transportability as they are typically underrepresented in the existing evidence base. We illustrate this problem by conducting a randomized field experiment on scalable, low-cost design elements to improve program take-up in one of the world’s largest en- ergy efficiency assistance programs. Observing investment decisions of over 1,800 low-income households in Germany’s “Refrigerator Replacement Program”, we find that the transportabil- ity problem is real and consequential: First, the most effective policy design would not have been chosen based on existing behavioral insights. Second, design elements favored by these insights either prove ineffective or even backfire, violating ‘do no harm’ principles of policy advice. Systematic testing remains crucial for addressing the transportability problem, partic- ularly for policies targeting vulnerable groups.\r\n"}],"type":"working_paper"},{"language":[{"iso":"eng"}],"ddc":["330"],"keyword":["Matching","School choice","College admission problems","Top trading cycles","Pareto efficiency","Strategy-proofness"],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":611017,"access_level":"closed","file_name":"1-s2.0-S0165489624000817-main.pdf","file_id":"56421","date_updated":"2024-10-08T11:53:39Z","creator":"nmaraun","date_created":"2024-10-08T11:53:39Z"}],"abstract":[{"text":"There are a number of school choice problems in which students are heterogeneous according to the number of seats they occupy at the school they are assigned to.

In order to reduce global energy consumption in production and industry along with the associated CO2 emissions, existing resources must be used more efficiently. This includes the energy-efficient and comprehensive recycling of a wide range of metals. Especially for the production of aluminium, there is a large potential for saving energy using efficient recycling processes. With regard to the recycling of aluminium studies have shown that solid-state recycling processes are significantly more efficient considering the used energy and resources compared to the conventional, smelting-metallurgical recycling process. In this paper, the direct and energy-efficient friction-induced recycling process (FIRP) based on the conform process is further described and analysed in terms of the temperature-property relationships. For this purpose, the influence of the processing temperature on the microstructure and properties of the recycled semi-finished products is investigated using the toll system that enables an ECAP forming. Specific sections of the (in theory) infinite, recycled semi-finished product are taken and analysed at different process temperatures of the solid state recycling process. Based on these sections, the properties in terms of mechanical hardness, strength, ductility and grain size are analysed and a degressive relationship between process temperature and mechanical hardness up to a temperature of 270 °C can be shown. Applying the Hall-Petch relationship, it is analysed whether there is a correlation between the strength and the microstructure in the form of the grain size. </jats:p>"}],"publication":"Materials Research Proceedings","type":"conference","language":[{"iso":"eng"}],"keyword":["Recycling","Aluminium","Friction-Induced","Energy Efficiency"],"department":[{"_id":"156"}],"user_id":"83141","_id":"44036"},{"_id":"24550","user_id":"28836","department":[{"_id":"53"}],"file_date_updated":"2022-01-06T13:20:31Z","type":"conference","status":"public","date_updated":"2022-01-06T13:22:03Z","author":[{"full_name":"Krauter, Stefan","id":"28836","orcid":"0000-0002-3594-260X","last_name":"Krauter","first_name":"Stefan"},{"last_name":"Bendfeld","id":"16148","full_name":"Bendfeld, Jörg","first_name":"Jörg"}],"doi":"10.4229/EUPVSEC20212021-4CO.3.4","conference":{"name":"38th European Photovoltaic Solar Energy Conference and Exhibition (EUPVSEC 2021)","start_date":"2021-09-06","end_date":"2021-09-10"},"publication_status":"published","publication_identifier":{"isbn":["3-936338-78-7"]},"has_accepted_license":"1","citation":{"mla":"Krauter, Stefan, and Jörg Bendfeld. “Module-Inverters (Microinverters): Influence of Module Size on Conversion Efficiencies and Energy Yields.” <i>Proceedings of the 38th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC 2021)</i>, 2021, pp. 659–63, doi:<a href=\"https://doi.org/10.4229/EUPVSEC20212021-4CO.3.4\">10.4229/EUPVSEC20212021-4CO.3.4</a>.","short":"S.

The inverters have been fed by identical and calibrated crystalline silicon PV modules of 215 Wp. To monitor accurately DC input, AC power output and energy yield, each of the micro-inverters has been equipped with a calibrated electricity meter. For micro-inverters requiring control units for grid-feeding that has been acquired also. The comparison covers efficiency-load characteristics as well as electrical energy yields. Purchase costs vary considerably between the models in comparison, sometimes inverter costs are higher than module costs, particularly if an additional grid-connection or interface device is needed for operation. The weighted conversion efficiency according to EU and CEC standards has been measured and calculated. While some inverters have been optimized for high irradiance levels, they ranked better at the CEC efficiency, others performed very well also for low irradiance levels, thus ranking higher at in the EU-efficiency tables. These results are deviating from the actual energy yield measurements, which show a slightly different ranking. At one inverter, an accurate, but very slow MPPT algorithm that barely could follow quickly changing irradiance levels could be the reason for this effect. Another inverter switched off after operation at high power output for a while. Apparently, some inverters are been optimized to show excellent EU and CEC efficiency ratings. Two of the inverters featuring two inputs did not show an exceptional performance at the EU- and CEC-ratings, but they achieved top ranks at the AC energy yield for the first years. For the customer, the AC yield is a major performance indicator of any microinverter and should be included in the datasheet."}]},{"page":"113-123","citation":{"bibtex":"@inproceedings{Koning_Polevoy_Meijer_de Laat_Grosso_2019, series={2019 6th IEEE International Conference on Cyber Security and Cloud Computing (CSCloud)/ 2019 5th IEEE International Conference on Edge Computing and Scalable Cloud (EdgeCom)}, title={Approaches for Collaborative Security Defences in Multi Network Environments}, DOI={<a href=\"https://doi.org/10.1109/CSCloud/EdgeCom.2019.000-9\">10.1109/CSCloud/EdgeCom.2019.000-9</a>}, booktitle={2019 6th IEEE International Conference on Cyber Security and Cloud Computing (CSCloud)/ 2019 5th IEEE International Conference on Edge Computing and Scalable Cloud (EdgeCom)}, author={Koning, Ralph and Polevoy, Gleb and Meijer, Lydia and de Laat, Cees and Grosso, Paola}, year={2019}, pages={113–123}, collection={2019 6th IEEE International Conference on Cyber Security and Cloud Computing (CSCloud)/ 2019 5th IEEE International Conference on Edge Computing and Scalable Cloud (EdgeCom)} }","short":"R.

We propose a new framework that uses SDNs and NFV to achieve this goal: Secure Autonomous Response Network (SARNET). In a SARNET, an agent running a control loop constantly assesses the security state of the network by means of observables. The agent reacts to and resolves security problems, while learning from its previous decisions. Two main metrics govern the decision process in a SARNET: impact and efficiency; these metrics can be used to compare and evaluate countermeasures and are the building blocks for self-learning SARNETs that exhibit autonomous response. In this paper we present the software implementation of the SARNET framework, evaluate it in a real-life network and discuss the tradeoffs between parameters used by the SARNET agent and the efficiency of its actions.","lang":"eng"}]},{"date_updated":"2022-01-06T06:53:16Z","publisher":"Springer","author":[{"first_name":"Gleb","id":"83983","full_name":"Polevoy, Gleb","last_name":"Polevoy"},{"last_name":"de Weerdt","full_name":"de Weerdt, M.M.","first_name":"M.M."}],"date_created":"2020-08-06T15:20:09Z","title":"Reciprocation Effort Games","year":"2017","citation":{"apa":"Polevoy, G., &#38; de Weerdt, M.

We find that a bank’s operational efficiency is priced in bank loan rates and alters interest-setting behavior. Specifically, we establish that a higher degree of operational efficiency leads to lower loan markups, which makes prices more competitive and smoothes the setting of interest rates. By employing state-of-the-art stochastic frontier efficiency measures to capture a bank’s operational efficiency, we take a look at the bank customers’ perspective and demonstrate the extent to which bor-rowers benefit from cost-efficient banking.

Online service providers may find themselves maxed out at peak operation levels during high-traffic timeslots but too little demand during low-traffic timeslots, although the latter is becoming less frequent. At this point not only deciding which user is allocated what level of service becomes essential, but also the magnitude of the service provided, can be controlled by pricing. Pricing is an important factor when efficient and acceptable allocation of resources between individuals must be reached. Without prices, transferring or sharing goods would be impossible. In sharing information, pricing a product however is not as simple as relatively pricing an apple or a pear. Often the costs, and hence the prices are simply unknown. Backed by this scenario, the online services market could be combined with the market design mechanism of diamonds. For this we propose an ultimatum pricing strategy which effectively allows for valuations to be accounted for, but no longer a necessity when pricing in grid, cloud or other online computing environments."}],"file":[{"file_size":247621,"access_level":"open_access","file_id":"6191","file_name":"Take it or leave it - ECIS - Proof.pdf","date_updated":"2018-12-13T15:20:13Z","date_created":"2018-12-11T15:22:41Z","creator":"hsiemes","relation":"main_file","content_type":"application/pdf"}],"status":"public","type":"conference","publication":"18th European Conference on Information Systems (ECIS 2010)"},{"publication":"Proceedings of the Workshop on Mobile Spatial Interaction at CHI 2007","type":"conference","status":"public","abstract":[{"text":"Location-aware services for private use such as GPS-\r\nbased navigation systems and GSM-based offerings\r\nhave become quite a success for outdoor applications,\r\nwhile indoor positioning systems are still mainly\r\nemployed for professional use only.
