Abstract Built infrastructure for water and energy supply, transportation, and other such services underpins human well‐being and socioeconomic development. A fundamental understanding of how infrastructure design and user strategies interact can guide important design decisions as well as policy formulation for ensuring long‐term infrastructure viability in conjunction with improved individual user benefits. In this work, an agent based model (ABM) is developed to study this issue for the specific case of irrigation canals. Cooperatively maintained irrigation canals serve essential roles in sustaining agriculture‐based economies in many regions. Canal system design can strongly affect benefits derived by distributed users, regional agricultural output, and the long‐term viability of the shared infrastructure itself. Here, an ABM is used to investigate how an option to use an independent water source interacts with canal design to affect canal maintenance cooperation and farmer income. The independent water source is stylized as a well that provides access to groundwater and represents astrategically robustdesign option; a design option that reduces the implementer's utility vulnerability to unfavorable actions by other actors. Research in other systems has demonstrated that strategically robust designs can improve both implementer utility and the probability of collaboration. The results of this research, in contrast, demonstrate that the option of individual resource access, the strategically robust design option, as represented by a well, reduces cooperative maintenance in most cases. However, wells also improve farmer income, especially for downstream farmers that are most affected by water theft.

Coping With Unreliable Water Supply: An Experimental Study of Exit and Voice
Abstract Unreliable public water supplies cause human hardships and are still common worldwide. Households often deal with the issue by adopting various coping strategies that are representative of economic decentralization (e.g., using private wells, sourcing from third‐party vendors) and political decentralization (e.g., making petitions to a public provider). There is growing interest in these user‐level decentralized coping strategies, but their relative effects on provider's behavior and the long‐term sustainability of public water supply remain unclear. This puzzle has not been tackled using an experimental approach. This study reports a controlled behavioral experiment conducted to test the relative effectiveness of different coping strategies on infrastructure quality and users‐provider cooperation in the context of agricultural water supply. We tested experimental treatments involving two classes of coping strategies:exitandvoice. The exit option represents users' shift to an alternative water source. The voice option represents users' direct effort to influence a public irrigation service provider. We recruited 272 human subjects into our 4‐player experiment (one provider and three users) and observed and compared their decisions under four treatments (exit, voice, their combination, and no options). The results show that the voice option leads to improved outcomes compared to other choices that include the exit option, suggesting that contrary to previously thought, the exit option can be detrimental to users‐provider cooperation. We also observed that a user tends to cooperate more (pay and use the public service) when other users do the same.

Abstract Collective action among public officials is necessary for the effective delivery of many social services, but relatively little is known about how it can be fostered through policy reforms. In this article, we compare cooperation among public officials within decentralized versus centrally‐administered municipalities in Honduras. Leveraging a quasi‐experiment in health sector reform, coupled with behavioral games and social network surveys, we find that decentralization is associated with greater cooperation. When they are able to communicate, health sector workers in decentralized municipalities contribute more to a public good than their centrally‐administered counterparts. This increase in cooperative behavior results in part from the decentralization reform engendering greater numbers of interactions and stronger ties across different levels of government. These findings indicate that institutional reforms like decentralization can favorably reconfigure patterns of social interactions across public organizations, which is an important component of administrative capacity in developing countries.more » « less

In Location-Based Services (LBS), users are required to disclose their precise location information to query a service provider. An untrusted service provider can abuse those queries to infer sensitive information on a user through spatio-temporal and historical data analyses. Depicting the drawbacks of existing privacy-preserving approaches in LBS, we propose a user-centric obfuscation approach, called KLAP, based on the three fundamental obfuscation requirements: k number of locations, l-diversity, and privacy area preservation. Considering user's sensitivity to different locations and utilizing Real-Time Traffic Information (RTTI), KLAP generates a convex Concealing Region (CR) to hide user's location such that the locations, forming the CR, resemble similar sensitivity and are resilient against a wide range of inferences in spatio-temporal domain. For the first time, a novel CR pruning technique is proposed to significantly improve the delay between successive CR submissions. We carry out an experiment with a real dataset to show its effectiveness for sporadic, frequent, and continuous service use cases.more » « less

Voice assistants capable of answering user queries during various physical tasks have shown promise in guiding users through complex procedures. However, users often find it challenging to articulate their queries precisely, especially when unfamiliar with the specific terminologies required for machine-oriented tasks. We introduce PrISM-Q&A, a novel question-answering (Q&A) interaction termed step-aware Q&A, which enhances the functionality of voice assistants on smartwatches by incorporating Human Activity Recognition (HAR) and providing the system with user context. It continuously monitors user behavior during procedural tasks via audio and motion sensors on the watch and estimates which step the user is performing. When a question is posed, this contextual information is supplied to Large Language Models (LLMs) as part of the context used to generate a response, even in the case of inherently vague questions like What should I do next with this? Our studies confirmed that users preferred the convenience of our approach compared to existing voice assistants. Our real-time assistant represents the first Q&A system that provides contextually situated support during tasks without camera use, paving the way for the ubiquitous, intelligent assistant.more » « less

Smart speakers come with always-on microphones to facilitate voice-based interaction. To address user privacy concerns, existing devices come with a number of privacy features: e.g., mute buttons and local trigger-word detection modules. But it is difficult for users to trust that these manufacturer-provided privacy features actually work given that there is a misalignment of incentives: Google, Meta, and Amazon benefit from collecting personal data and users know it. What’s needed is perceptible assurance — privacy features that users can, through physical perception, verify actually work. To that end, we introduce, implement, and evaluate the idea of “intentionally-powered” microphones to provide users with perceptible assurance of privacy with smart speakers. We employed an iterative-design process to develop Candid Mic, a battery-free, wireless microphone that can only be powered by harvesting energy from intentional user interactions. Moreover, users can visually inspect the (dis)connection between the energy harvesting module and the microphone. Through a within-subjects experiment, we found that Candid Mic provides users with perceptible assurance about whether the microphone is capturing audio or not, and improves user trust in using smart speakers relative to mute button interfaces.more » « less
