Inference in dynamic stochastic general equilibrium models with possible weak identification

Qu, Zhongjun - In: Quantitative economics : QE ; journal of the … 5 (2014) 2, pp. 457-494

This paper considers inference in log-linearized dynamic stochastic general equilibrium (DSGE) models with weakly (including un-) identified parameters. The framework allows for analysis using only part of the spectrum, say at the business cycle frequencies. First, we characterize weak...

Testing identifying assumptions in fuzzy regression discontinuity designs

Arai, Yoichi; Hsu, Yu-Chin; Kitagawa, Toru; Mourifié, … - In: Quantitative economics : QE ; journal of the … 13 (2022) 1, pp. 1-28

We propose a new specification test for assessing the validity of fuzzy regression discontinuity designs (FRD‐validity). We derive a new set of testable implications, characterized by a set of inequality restrictions on the joint distribution of observed outcomes and treatment status at the...

This method "leaves out the neighbors" when fitting nuisance components, and we …‐dimensional. In heterogeneous panel data settings, we model the unobserved unit heterogeneity as a weakly sparse deviation from …

Specification testing in random coefficient models

Breunig, Christoph; Hoderlein, Stefan - In: Quantitative economics : QE ; journal of the … 9 (2018) 3, pp. 1371-1417

In this paper, we suggest and analyze a new class of specification tests for random coefficient models. These tests allow to assess the validity of central structural features of the model, in particular linearity in coefficients, generalizations of this notion like a known nonlinear functional...

Improved inference on the rank of a matrix

Chen, Qihui; Fang, Zheng - In: Quantitative economics : QE ; journal of the … 10 (2019) 4, pp. 1787-1824

This paper develops a general framework for conducting inference on the rank of an unknown matrix Π0. A defining feature of our setup is the null hypothesis of the form . The problem is of first‐order importance because the previous literature focuses on by implicitly assuming away , which...

Sensitivity analysis using approximate moment condition models

Armstrong, Timothy B.; Kolesár, Michal - In: Quantitative economics : QE ; journal of the … 12 (2021) 1, pp. 77-108

We consider inference in models defined by approximate moment conditions. We show that near-optimal confidence intervals (CIs) can be formed by taking a generalized method of moments (GMM) estimator, and adding and subtracting the standard error times a critical value that takes into account the...

Specification tests for non-Gaussian maximum likelihood estimators

Fiorentini, Gabriele; Sentana, Enrique - In: Quantitative economics : QE ; journal of the … 12 (2021) 3, pp. 683-742

We propose generalized DWH specification tests which simultaneously compare three or more likelihood-based estimators in multivariate conditionally heteroskedastic dynamic regression models. Our tests are useful for Garch models and in many empirically relevant macro and finance applications...

Concave-monotone treatment response and monotone treatment selection : with an application to the returns to schooling

Okumura, Tsunao; Usui, Emiko - In: Quantitative economics : QE ; journal of the … 5 (2014) 1, pp. 175-194

This paper identifies sharp bounds on the mean treatment response and average treatment effect under the assumptions of both the concave-monotone treatment response (concave-MTR) and the monotone treatment selection (MTS). We use our bounds and the U.S. National Longitudinal Survey of Youth 1979...
