Admissibility under the Frequentist's Validity Constraint in Estimating the Loss of the Least-Squares Estimator

We consider the problem of estimating the sum of squared error loss L = [beta]-[beta]2 of the least-squares esitmator [beta] for [beta], the regression coefficient. The standard estimator L0 is the expected value of L.

Large‐Dimensional Cointegrated Threshold Factor Models: The Global Term Structure of Interest Rates

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT In this paper we extend the two‐level factor model to account for cointegration between group‐specific factors in large datasets. We propose two nonlinear specifications: (i) a threshold vector error correction model (VECM) that allows for asymmetric adjustment across regimes; and (ii) a band VECM that captures state‐dependent adjustment which

Detecting Sparse Cointegration

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We propose a two‐step procedure for detecting sparse cointegration in high‐dimensional single‐equation models. First, we employ the adaptive lasso to identify the subset of integrated covariates driving the long‐run equilibrium relationship.

Inequality of Opportunity in a Multiperiod Framework

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper offers a simple model to evaluate and measure inequality of opportunity in a multiperiod framework, in which both circumstances and effort may change over time. We adopt a norm‐based approach and an axiomatic methodology: we first characterise two alternative definitions of a ‘fair distribution’, associated respectively with the ex ...

AI in Public Decision‐Making: A Philosophical and Practical Framework for Assessing and Weighing Harm and Benefit

Public Administration, EarlyView.
ABSTRACT Artificial intelligence (AI) is increasingly used in public decision‐making; yet existing governance tools often lack clear definitions of harm and benefit, practical methods for weighing competing values, and guidance for resolving value conflicts.
