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

Tariff: The Most Beautiful Word in the Dictionary?
Review of International Economics, EarlyView.ABSTRACT We consider the welfare impacts of US tariff policy at levels proposed by President Donald J. Trump. General‐equilibrium simulations under a widely used transparent one‐sector trade model reveal sizable US welfare losses. When we extend the model to include bilateral firm selection and high resolution input–output linkages, the US losses ...

Markup Centrality and International Incidence in Global Production Networks
Review of International Economics, EarlyView.ABSTRACT This paper develops a framework to measure how markups amplify prices through global production networks and to attribute final‐demand price wedges to upstream country‐industry sources. The approach defines a compound markup as the ratio of observed prices to counterfactual pure‐cost prices that would prevail if all markups in the network were

Image of mathematics: A case study of two women's early mathematics experiences
School Science and Mathematics, EarlyView.Abstract People often view mathematics as abstract, cold, and irrelevant to real life, and their school experiences likely influence such views. In this case study, we investigated the mathematics experiences of two women who participated in an afterschool girls‐only STEM club 30 years ago when they were in fifth and sixth grades.

School Science and Mathematics, EarlyView.ABSTRACT This study investigates the impact of problem‐posing on the mathematical proficiency and engagement of 56 Developmental Mathematics (DM) students enrolled in a noncredit college mathematics course. Using a quasi‐experimental design, one of two existing classes was selected as the experimental group and received a 5‐week intervention focused on

School Science and Mathematics, EarlyView.ABSTRACT This study examines the predictive relationships among early mathematics and reading achievement, school discipline, and later mathematics performance for Black students. Using path analysis, we analyze a cohort of 36,668 Black students in Texas public schools from fourth to seventh grade.
