Clay weekly context brief for the Economics category (ISO week 2026-W31).

Clay tracks publications from the Economics feed list. Below are recent items from this category, each with its source and a short description of what the publication covers when one is available in the source feed.

Recent publications:
1. Monotonicity and Bracketing in Games
   Source: econ.TH (Theoretical Economics)
   Link: https://arxiv.org/abs/2502.11243
   We study solution concepts for normal-form games.
2. Educational Assortative Mating and Household Income Inequality: Evidence from Brazil, Indonesia, Mexico, and South Africa
   Source: econ.GN (General Economics)
   Link: https://arxiv.org/abs/2503.02713
   This paper presents new empirical evidence from four emerging economies on the relationship between educational assortative mating and household income inequality.
3. Robust Two-Sample Inference under Serial Dependence
   Source: econ.EM (Econometrics)
   Link: https://arxiv.org/abs/2512.11259
   We propose robust inference for two-sample comparison with time-series data under serial dependence and heterogeneous long-run variances.
4. Natural Invariant Measures for Chaotic Game Dynamics: Finding Order in Chaos
   Source: econ.TH (Theoretical Economics)
   Link: https://arxiv.org/abs/2607.21805
   We study the long-term behavior of the Multiplicative Weights Update (MWU) algorithm in game settings where learning dynamics frequently fail to converge to Nash equilibria and instead exhibit Li-Yorke chaos.
5. How Do Regulations and Technology Affect Service Allocation and Market Structure?
   Source: econ.GN (General Economics)
   Link: https://arxiv.org/abs/2410.22616
   The paper estimates the effects of Price Controls and Cost Controls on healthcare service quantity and their role in spatial restructuring of physician market.
6. Identification of Heterogeneous Peer Effects
   Source: econ.EM (Econometrics)
   Link: https://arxiv.org/abs/2410.14317
   We develop a model of peer effects where each peer has a separate effect depending on their rank in the distribution of peers' outcomes.
7. Latent Fragility and Clustered Withdrawals in Dynamic Banks Runs
   Source: econ.TH (Theoretical Economics)
   Link: https://arxiv.org/abs/2607.22317
   Using a mean-field game framework, we study a dynamic model of bank runs in which more withdrawals raise the risk of bank failure.
8. Unfit for stranding assessment: a panel-scale multimodal-LLM audit of building-decarbonisation disclosure (BeDA)
   Source: econ.GN (General Economics)
   Link: https://arxiv.org/abs/2607.22006
   Buildings account for roughly 34% of global final energy use and 37% of energy- and process-related CO$_2$ emissions.
9. CausalForge: A Formally Grounded, Self-Improving Agentic Framework for Automated Research in Causal Inference
   Source: econ.EM (Econometrics)
   Link: https://arxiv.org/abs/2607.22511
   Automating theoretical research is constrained not only by the generation of candidate results, but also by their reliable evaluation.
10. Strategic Exit and Unilateral Control
   Source: econ.TH (Theoretical Economics)
   Link: https://arxiv.org/abs/2607.21898
   Repeated-game strategies can impose global payoff relations by balancing controlled rewards across time.
11. Are cryptocurrencies real financial bubbles? Evidence from quantitative analyses
   Source: econ.GN (General Economics)
   Link: https://arxiv.org/abs/2607.21826
   The growth of peer-to-peer exchanges and the blockchain technology has led to a proliferation of cryptocurrencies and to a massive increase in the number of investors who actually negotiate digital money.
12. Interventional Score Geometry for Causal Inference
   Source: econ.EM (Econometrics)
   Link: https://arxiv.org/abs/2607.21914
   Let $p(x)$ be the joint density of variables $X$, and let $\psi(x)=\nabla_x\log p(x)$ be its score field.
13. A Revelation Principle for Rationalizability
   Source: econ.TH (Theoretical Economics)
   Link: https://arxiv.org/abs/2607.21851
   We establish a revelation principle for interim correlated rationalizability.
14. Nonlinear Boosting with Multiple Testing in High-Dimensional Generalised Linear Models with Binary Responses
   Source: econ.EM (Econometrics)
   Link: https://arxiv.org/abs/2607.22440
   This paper proposes a nonlinear boosting with multiple testing (BMT) approach to variable selection in high-dimensional generalised linear models with binary responses.
