$SL(2,R)$ symmetry and quasi-normal modes in the BTZ black hole
, 2011 With the help of two new intrinsic tensor fields associated with the $SL(2,R)$ quadratic Casimir of Killing fields, we uncover the $SL(2,R)$ symmetry satisfied by the solutions to the equations of motion for various fields in the BTZ black hole in a ...

Evidence and skepticism in verifiable disclosure games
Theoretical Economics, Volume 20, Issue 4, Page 1213-1246, November 2025.A key feature of communication with evidence is skepticism: a receiver will attribute any incomplete disclosure to the sender concealing unfavorable evidence. I study when a change in the receiver"s prior belief about the sender's evidence induces more skepticism, i.e., induces the receiver, regardless of his preferences, to take an equilibrium action ...

Loop gravity in terms of spinors
, 2011 We show that loop gravity can equally well be formulated in in terms of spinorial variables (instead of the group variables which are commonly used), which have recently been shown to provide a direct link between spin network states and discrete ...

Theoretical Economics, Volume 20, Issue 4, Page 1181-1211, November 2025.We study project selection and development by a principal, interacting with two agents, each of whom wants his respective project selected. When the best choice is uncertain, keeping both projects alive gives the principal the ability to adapt her choice in the future, but implies an efficiency loss of effort being spent on the project finally not ...

SAGE Open, 2023 Private information puts naïve traders at a significant trading disadvantage and at the same it provide crucial signals managers for investment adjustment. These two forces have opposing effects on the cost of equity, and the overall effect is determined

Theoretical Economics, Volume 20, Issue 4, Page 1285-1322, November 2025.Implementation theory is concerned with the existence of mechanisms in which, at each state of the world, all equilibria result in outcomes that are within a given social choice correspondence (SCC). However, if agents make mistakes, if their preferences or the solution concept are misspecified, or if the designer is limited in what can be used as ...

Theoretical Economics, Volume 20, Issue 4, Page 1323-1365, November 2025.How best to incentivize prompt disclosure? We study this question in a general model in which a technological breakthrough occurs at an uncertain time and is privately observed by an agent, and a principal must incentivize disclosure via her control of a payoff‐relevant physical allocation.

Greenwashing: Motivations, causes and consequences
International Review of Economics & FinanceWe discuss motives and outcomes of corporate greenwashing as well as factors that contribute to it. We argue that in the presence of benefits accrued to corporate social responsibility, economic agents with short-term horizons may be incented to engage ...

Probabilistic verification in mechanism design
Theoretical Economics, Volume 20, Issue 4, Page 1247-1284, November 2025.We introduce a model of probabilistic verification in mechanism design. The principal elicits a message from the agent and then selects a test to give the agent. The agent's true type determines the probability with which he can pass each test. We characterize whether each type has an associated test that best screens out all other types.

The lightest scalar meson in a simple approach [PDF]
, 2013 We study basic properties of scalar hadronic resonances within a quantum field theoretical toy model. In particular, we focus on the spectral function, the mass and the decay width of the resonance $f_{0}(500)$.
