A structure-conduct-performance approach to language complexity trade-offs

Coloma, Germán - 2026

In this paper, we present an approach to relate typological measures of language complexity (based on the grammars of different languages) with empirical measures of that complexity (based on actual texts). It is known as the "structure-conduct-performance paradigm", and we have taken it from...

Comparison of two types of topological networks for the foreign exchange market : one based on correlation coefficients and the other on the concept of causality

Landmesser-Rusek, Joanna - 2026

Topological networks make it possible to recognize structural properties of the currency market. Such networks can be constructed on the basis of the values of correlation coefficients between currency pairs, and the popular minimum spanning tree (MST) algorithm allows an understanding of...

Commonality of information and commonality of beliefs

Awaya, Yu; Krishna, Vijay - 2025

A group of agents with a common prior receive informative signals about an unknown state repeatedly over time. If these signals were public, agents' beliefs would be identical and commonly known. This suggests that if signals were private, then the more correlated these are, the greater the...

Information transmission and countervailing biases in organizations

Chiba, Saori - 2024

A decision maker (DM) must choose between two projects or decide on no project. The expected benefits of these projects are correlated. The DM seeks advice from an agent with private information about the projects' benefits. However, the agent's divergent preferences for projects and lack of...

The role of data and priors in estimating climate sensitivity

In Bayesian theory, the data together with the prior produce a posterior. We show that it is also possible to follow the opposite route, that is, to use data and posterior information (both of which are observable) to reveal the prior (which is not observable). We then apply the theory to...
