We experimentally test how the content of advice, namely, its alignment with common priors, influences beliefs about its quality and future demand for it. We reject the theoretical hypothesis that demand for advice can be increased by giving advice in alignment with common priors. We find,...

Invariant coordinate selection (ICS) is a dimension reduction method, used as a preliminary step for clustering and outlier detection. It has been primarily applied to multivariate data. This work introduces a coordinate-free definition of ICS in an abstract Euclidean space and extends the method...

Invariant Coordinate Selection (ICS) is a multivariate technique that relies on the simultaneous diagonalization of two scatter matrices. It serves various purposes, including its use as a dimension reduction tool prior to clustering or outlier detection. ICS’s theoretical foundation establishes...

We develop a leverage theory of tying in markets with network effects. When a monopolist in one market cannot perfectly extract surplus from consumers, tying can be a mechanism through which unexploited consumer surplus is used as a demand-side leverage to create a “quasi-installed base” advantage...

The frontier of artificial intelligence (AI) is constantly moving, raising fears and concerns whenever AI is deployed in a new occupation. Some of these fears are legitimate and should be addressed by AI developers-but others may result from psychological barriers, suppressing the uptake of a...

We study collusion among firms against imperfectly monitored environmental regulation. Firms increase variable profits by violating regulation and reduce expected noncompliance penalties by violating jointly. We consider a case of three German automakers colluding to reduce the effectiveness of...

Westudy the problem of bivariate discrete or continuous probability density estimation under low-rank constraints. For discrete distributions, we assume that the two-dimensional array to estimate is a low-rank probability matrix. In the continuous case, we assume that the density with respect to...

Women’s decision-making power within households is a critical aspect of gender equality, influencing the well-being of household members and family dynamics. This study examines women’s perceived autonomy in household decision-making among BaYaka hunter-gatherers and Bandongo fisher-farmers in a...

With AI now passing the bar, and with increasing court caseloads worldwide hampering access to justice, there are calls for judges to make use of chatbots to help expedite their work. Such calls pose a normative question: whether our ideal of the rule of law is consistent with judicial reliance on...
