On the limitations of data‐based price discrimination
Theoretical Economics, Volume 20, Issue 1, Page 303-351, January 2025.The classic third degree price discrimination (3PD) model requires the knowledge of the distribution of buyer valuations and the covariate to set the price conditioned on the covariate. In terms of generating revenue, the classic result shows that 3PD is at least as good as uniform pricing.

Razionamento del credito e dimensioni di impresa (Credit rationing and firm size)
Moneta e Credito, 2012 This paper examines the likelihood of credit rationing faced by firms of different size. Cantrary to common thought, several recent contributions on this topic argue that, when rationing credit, size alone is not a sufficient condition for ...

Two-photon decay of heavy hadron molecules [PDF]
Phys.Rev.D82:054010,2010, 2010 We discuss the two-photon decay width of heavy hadron molecules and study the dependence on the constituent meson masses and on the binding energy. In addition finite size effects due to the extended structure of the bound state are shown to have a strong influence on the predictions for this decay width.

Can Technology Solve the Principal-Agent Problem? Evidence from China's War on Air Pollution
Social Science Research Network, 2020 We examine the introduction of automatic air pollution monitoring to counter suspected tampering at the local level, a central feature of China’s “war on pollution.” Exploiting 654 regression discontinuity designs based on city-level variation in the day

Twenty-first Century Lattice Gauge Theory: Results from the QCD Lagrangian
, 2012 Quantum chromodynamics (QCD) reduces the strong interactions, in all their variety, to a simple nonabelian gauge theory. It clearly and elegantly explains hadrons at short distances, which has led to its universal acceptance.

Finance research over 40 years: What can we learn from machine learning?
International Studies of Economics, Volume 19, Issue 4, Page 472-507, December 2024.Abstract We apply machine learning models to a universe of 20,185 finance articles published between 1976 and 2015 on 17 finance journals, and objectively identify 38 research topics. The financial crisis, hedge/mutual fund, social network, and culture were the fastest growing topics, while market microstructure, initial public offering, and option ...

Uniqueness Theorem for Stationary Axisymmetric Black Holes in Einstein-Maxwell-axion-dilaton Gravity [PDF]
Phys.Rev.D82:044017,2010, 2010 We prove the uniqueness theorem for stationary axisymmetric black hole solution in Einstein-Maxwell-axion-dilaton gravity being the low-energy limit of the heterotic string theory. We consider both non-degenerate and extremal Kerr-Sen black hole solutions.

On the role of patience in an insurance market with asymmetric information [PDF]
, 2006 We analyse a 2-period competitive insurance market which is characterized by the simultaneous presence of standard moral hazard and adverse selection with regard to consumer time preferences.
