Sludge and transaction costs

Abstract Behavioral scientists have begun to research ‘sludge,’ excessive frictions that make it harder for people do what they want do. Friction is also an important concept in transaction-cost economics. Nevertheless, sludge has been discussed without explicit referral transaction costs. Several questions arise from this observation. Is the analogy friction used differently both literatures? If so, are key differences? not, should we develop of when well-established literature on costs already exists? This conceptual article shows and related, but distinct, concepts, can benefit incorporating elements research. For example, suggest defining as aspects choice architecture lead experience costs, organize sludges using a typology inspired by literature, highlight specificity, uncertainty, frequency determinants ‘sludginess’ architecture, show audits be conducted methods developed literature.
