Household Water Use For Circular Transitions: Elasticity Estimates And Circular Economy Signals From Metro Manila, Albert E. Lamberte, Abed Alaswad, Luciano C. Batista

Angelo King Institute for Economic and Business Studies (AKI)

The study examines household water demand in Metro Manila and evaluates how demand behavior and infrastructure access shape the transition from a linear to a circular water and wastewater economy. Estimated prices, ranging from -0.441 to 0.468, and income elasticities, which are between 0.550 and 0.572, for those with and without access to both water and sewerage systems reveal consistently inelastic demand. Thus, water is treated as a necessity with limited behavioral responsiveness to tariff changes. The similarity of elasticities across service groups suggests that behavioral factors are not the primary constraint to circularity. Instead, the findings highlight that infrastructure …

How Much Should A Conversational Recommender System Converse?, Akshit Kumar, Vahideh Manshadi, Akhilesh Tumu

Cowles Foundation Discussion Papers

Conversational recommender systems powered by generative AI can enhance personalization by facilitating information elicitation through follow-up questions. However, engaging in these conversations imposes a communication cost on users. As platforms with different objectives and monetization models deploy these systems, a central question is: how does the platform’s objective and sellers’ strategic response shape the design of these systems in terms of their elicitation strategy? We develop a parsimonious model of conversational elicitation in which interaction generates noisy preference information and imposes a communication cost borne by the user. A user-welfare-maximizing platform elicits more information when accurate niche matching yields large …
