Integrated correlators in SYM beyond localisation
Augustus Brown, Paul Heslop, Congkao Wen +1
We study integrated correlators of four superconformal primaries with arbitrary charges in super Yang-Mills theory (SYM). The $ \langle \mat…
Grenander-type Density Estimation under Myerson Regularity
Haitian Xie
This study presents a novel approach to the density estimation of private values from second-price auctions, diverging from the conventional use of smoothing-based estimators. We i…
Employer Reputation and the Labor Market: Evidence from Glassdoor.com and Dice.com
Ke, Ma, Sophie Yanying Sheng +1
How does employer reputation affect the labor market? We investigate this question using a novel dataset combining reviews from Glassdoor.com and job applications data from Dice.co…
Generating functions and large-charge expansion of integrated correlators in supersymmetric Yang-Mills theory
Augustus Brown, Congkao Wen, Haitian Xie
We recently proved that, when integrating out spacetime dependence with a certain measure, four-point correlators $\langle \mathcal{O}_2\mathcal{O}_2\mathcal{O}^{(i)}_p \mathcal{O}…
Laplace-difference equation for integrated correlators of operators with general charges in SYM
Augustus Brown, Congkao Wen, Haitian Xie
We consider the integrated correlators associated with four-point correlation functions in four-…
Modular-invariant large- completion of an integrated correlator in supersymmetric Yang-Mills theory
Daniele Dorigoni, Michael B. Green, Congkao Wen +1
The use of supersymmetric localisation has recently led to modular covariant expressions for certain integrated correlators of half-BPS operators in supersymmetri…
On the limitations of data-based price discrimination
Haitian Xie, Ying Zhu, Denis Shishkin
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 covar…
Nonlinear and Nonseparable Structural Functions in Fuzzy Regression Discontinuity Designs
Haitian Xie
Many empirical examples of regression discontinuity (RD) designs concern a continuous treatment variable, but the theoretical aspects of such models are less studied. This study ex…
Personalized Subsidy Rules
Yu-Chang Chen, Haitian Xie
Subsidies are commonly used to encourage behaviors that can lead to short- or long-term benefits. Typical examples include subsidized job training programs and provisions of preven…
Uniform Convergence Results for the Local Linear Regression Estimation of the Conditional Distribution
Haitian Xie
This paper examines the local linear regression (LLR) estimate of the conditional distribution function . We derive three uniform convergence results: the uniform bias expa…
Strength in Numbers: Robust Mechanisms for Public Goods with Many Agents
Jin Xi, Haitian Xie
This study examines the mechanism design problem for public goods provision in a large economy with independent agents. We propose a class of dominant-strategy incentive compat…
Finite-Sample Average Bid Auction
Haitian Xie
The paper studies the problem of auction design in a setting where the auctioneer accesses the knowledge of the valuation distribution only through statistical samples. A new frame…
Global Representation of the Conditional LATE Model: A Separability Result
Yu-Chang Chen, Haitian Xie
This paper studies the latent index representation of the conditional LATE model, making explicit the role of covariates in treatment selection. We find that if the directions of t…
Efficient and Robust Estimation of the Generalized LATE Model
Haitian Xie
This paper studies the estimation of causal parameters in the generalized local average treatment effect (GLATE) model, a generalization of the classical LATE model encompassing mu…
