R parity violating supersymmetric explanation for the CDF Wjj excess

, 2011
Recently CDF has reported a 4.1 sigma excess in the distribution of the dijet invariant mass between 120-160 GeV in Wjj event sample in 7.3 fb^{-1} of data, which has generated considerable interest. We offer a possible explanation of this observation in

Adoption epidemics and viral marketing

Theoretical Economics, Volume 20, Issue 2, Page 453-480, May 2025.
An innovation (e.g., new product or idea) spreads like a virus, transmitted by those who have previously adopted it. Agents update their beliefs about innovation quality based on private signals and when they hear about the innovation. We characterize equilibrium adoption dynamics and the resulting lifecycle of virally‐spread innovations.

Should rational socioeconomic agents attempt to exert ‘control’ over the evolution of their preference or behavioral parameters?

Social Sciences and Humanities Open, 2023
Let a ‘heuristic’ be any preference or behavior that is anticipated to facilitate the achievement of some long-term objective, to wit, an objective which comprises of, at the very least, two sequential sub-objectives. The choice of any specific heuristic

Mental Models and Learning: The Case of Base-Rate Neglect

The American Economic Review
We experimentally document persistence of suboptimal behavior despite ample opportunities to learn from feedback in a canonical updating problem where people suffer from base-rate neglect. Our results provide insights on the mechanisms hindering learning

Symmetry breaking and restoration for interacting scalar and gauge fields in Lifshitz type theories

, 2012
We consider the one-loop effective potential at zero and finite temperature in field theories with anisotropic space-time scaling, with critical exponent $z=2$, including both scalar and gauge fields.

Initial conditions for evolution of double parton distributions [PDF]

, 2013
Double parton distribution functions (DPDFs) are used in the QCD description of double parton scattering. The DPDFs evolve with hard scales through relatively new QCD evolution equations which obey nontrivial momentum and valence quark number sum rules ...

An analytical model of search and bargaining with divisible money

Theoretical Economics, Volume 20, Issue 2, Page 713-761, May 2025.
We propose a standard search and bargaining model with divisible money, in which only the random matching market opens and the generalized Nash bargaining settles each trade. Assuming fixed production costs, we analytically characterize a tractable equilibrium, called a pay‐all equilibrium, and prove its existence. Each buyer pays all the money holding

Everyday Econometricians: Selection Neglect and Overoptimism When Learning from Others

American Economic Journal: Microeconomics
This study explores selection neglect in an experimental investment game where individuals can learn from others’ outcomes. Experiment 1 examines aggregate-level equilibrium behavior.

Multiple Pathways of Visual Adaptations for Water Column Usage in an Antarctic Adaptive Radiation

Ecology and Evolution, Volume 15, Issue 3, March 2025.
By investigating the diversification of the visual system in notothenioids, we reveal lineages at equivalent depths often depict extremes in eye size with striking convergences in tuning sites between distantly related species that are likely driven by the unusual environmental conditions of the Southern Ocean.
