Summary: According to recent studies, the demand for organic food is driven more by personal health concerns rather than environmental considerations. This raises concerns about the impact of conflicting health and environmental claims on consumer choices, particularly as new health-related allegations emerge. To examine this issue in the context of wine, which is currently considered harmful but still attracts health-conscious consumers due to the availability of new no-added-sulfites labels, an experimental market was created where Bordeaux wines were tasted. Surprisingly, the study reveals that the niche group of organic wine buyers penalizes the presence of sulfites in organic wines more than in conventional wines, which poses a threat to the credibility of organic certification.

Summary: Based on unique data from Swedish households, the study analyzes the price elasticity of electricity demand for households under a mandatory non-linear distribution tariff. The findings indicate that the price elasticity is smaller than expected, and that 2SLS estimates are not robust. This leads to discussions on alternative tariff designs to address weak incentives at the end of the month.

Summary: The study found that manipulating irrelevant anchors and providing different incentives only made a significant difference in hypothetical data, suggesting that hypothetical market research methods may provide lower quality data. This contributes to the discussion on the mechanism underlying the anchoring effect, indicating it may partly be caused by insufficient conscious effort to move away from the anchor.

Summary: Explaining complex or seemingly simple machine learning models is an important practical problem. The Shapley value framework is a game theoretic concept that can be used to explain individual predictions from such models. However, current methods like Kernel SHAP may produce misleading explanations when features are correlated.

Summary: Word-of-Mouth communication through online reviews is important for customers' purchasing decisions. This paper models customer preferences based on perceived service quality from Word-of-Mouth and integrates it into a retailer's operational problem. It analyzes the long-term behavior of customer demand and proposes that cyclic policies should be considered for optimal solutions. Published by Elsevier Ltd.

Summary: The study finds that the all-pay sealed-bid auction with revealed payments outperforms other mechanisms in terms of revenue, but it underperforms in efficiency compared to winner-pay auctions.

Summary: This study extends the symmetrical multi-unit auction to the asymmetric private value model by modelling the difference amongst bidders using valuation and marginal utility parameters. It solves the optimal strategy for different bidders, expanding the practical application of multi-unit auction theory. The study evaluates the yield and price volatility of different auction mechanisms under the 'two-group case', and the results show that Vickrey auction is generally superior to uniform price auction, while discriminatory price auction revenue has a larger fluctuation range.

Summary: This paper examines the impact of renewable energy auctions on innovation through a literature review, and finds that auctions are not effective in encouraging innovation compared to administratively-set feed-in tariffs.

Summary: Climate change is predicted to increase the frequency and intensity of extreme events, impacting the harshness of the environment and tree growth under natural conditions. Traditional single dose-effect approach is deemed inadequate in explaining the complex genotype-environment interactions in open field or forest stands. There is a need to develop new approaches and technologies to define suitable threshold responses of trees under suboptimal natural conditions.

Summary: This study investigates the optimal information disclosure policy in optimal and second-price auctions when the seller has information that adjusts the bidders' private values. It finds that in the optimal auction, the revenue function is convex in the additive adjustments, leading to a benefit from revealing information, while in the second-price auction, the revenue function is non-convex, suggesting a potential benefit from withholding information.

Summary: In an experiment on laying ducks involving an increased workload to access the nest, it was found that higher workloads and inability to access the nest had an impact on stress-induced hyperthermia, but not on egg corticosterone. The act of laying eggs in ducks may be due to frustration from the inability to access their preferred nest, leading to stress-induced hyperthermia.

Summary: This study investigates the spectral broadening and breathing behavior of transient dissipative structures produced asynchronously during the buildup process of dissipative solitons, revealing a novel dynamics of dissipative soliton generation including energy quantization, spectral broadening induced by self-phase modulation, structural dissipative soliton formation, and Raman soliton self-frequency shifting.

Summary: This paper investigates the impact of demands on system hazard rate, showing unexpected behavior in the intermediate to high demand regions. Depending on the SIS repair scheme, the calculation of PFH leads to conservative results in the high and continuous demand regions. New asymptotic equations are proposed for evaluating the PFH of kooN systems for all demand rates.

Summary: Research suggests that when people apply the term "likely" to continuous variables, it describes the most likely outcome or interval, regardless of actual probabilities. Participants tend to overestimate the chances of central, low-probability segments.

Summary: In this article, cost assumptions for solar and wind technologies in global, regional, and national energy scenario studies were systematically compared with actual costs and recent market auction prices. It was found that future energy scenario analyses tend to underestimate the rapid cost declines of renewable technologies, leading to an underestimation of their future role and deployment levels. The recommendation was made to establish an open database for renewable technology costs to enhance the accuracy and transparency of future energy scenarios.
