A theoretical economics paper develops a common-unit framework for interpersonal utility comparisons. Its results are conditional on mathematical assumptions, and an illustrative tax example gives different policy choices under two welfare criteria.

A theoretical preprint develops a PDE-based hedge for general one-dimensional diffusion markets and reports minimum hedging capital when an equivalent local martingale measure exists, while a no-ELMM simulation does not establish minimality.

A model of a local service economy finds that payroll-supported demand can make firms' technology choices reinforce one another, leaving expectations to shape whether automation or augmentation takes hold.

A theoretical preprint gives equivalent ways to recognize weak acyclicity in finite pure-strategy games, while showing that some perfect-information games can cycle under best-improvement moves yet still reach equilibrium along another path.

A preprint analysis links dual-class recapitalizations with higher valuation and patent-citation output, while unification is associated with lower valuation and declining citation output.

A formal two-trader economy produces exact equilibrium and convergence results, but its welfare claims are tied to a narrow feasible set and an unproved conjecture about trading order.

The paper models strategic altruism as Berge equilibrium and reports that it rules out some social choice goals on an unrestricted preference domain, while a restricted matching domain provides an exception.

A methods preprint compares data-compression model selection with standard criteria across simulations and three economic reanalyses, finding different recovery rates and model rankings.

A theoretical economics preprint examines whether a principal can delegate robustly when an agent's information distribution is unknown but its mean is known. It finds that a randomized upper cap can beat deterministic caps in the model, while the result remains conditional on quadratic loss, constant bias and the paper's stated assumptions.

A theoretical analysis says directed Kullback–Leibler divergences can characterize dominance between finite binary experiments when stopping depends on observed evidence, but it does not settle the same question beyond two states.

An arXiv preprint reports that the pace of change in S&P 500 co-movement is associated with the paper’s noncanonical volatility-premium measure. The relationship appears first in implied variance and later in realized variance, but the index did not improve the study’s timing comparison or act as a crash hedge.

An arXiv preprint offers a formal characterization of objective functions for ordinal or interval-scaled data. Under a common affine transformation rule, it says an adequate function must rely on one unique component, while city block and Euclidean dissimilarity measures remain adequate under a narrower transformation group.

A preprint reports that a daily LLM importance score could not affect later forecasts after calibration set all four weights to zero. A post-hoc signed repair found no familywise-corrected improvement, while headline count improved one SPY variance endpoint.
