  File: Replication Package Paper Title: Measuring Corruption from Household Income and Consumption Micro-Data: An International Perspective Authors: Nicolas Sarullo (University of California, Berkeley) Prof. Yuriy Gorodnichenko (University of California, Berkeley) Prof. Tatyana Deryugina (University of Illinois, Urbana-Champaign) James Hodson (AI for Good) Ilona Sologoub (VoxUkraine) Prof. Anastassia Fedyk (University of California, Berkeley) Date: February 11, 2026 Overview: This replication package provides all publicly available data along with code and instructions required to reproduce the empirical results of the research paper. The data is sourced from numerous household and individual level country survey data which are harmonized for analysis. These data are utilized to construct an objective measure of corruption in the public sector for a broad spectrum of countries using consumption-income gaps for public sector workers relative to private sector workers. The package was created to allow independent verification of the statistical findings reported in the paper. Processed and shuffled data are included for confidential sources in order to fulfill confidentiality agreements and minimize user friction.

• Do Consulting Services Affect Audit Quality? Evidence from the Workforce

  The Accounting Review · 2026-02-03

  articleOpen access1st authorCorresponding

  ABSTRACT This paper investigates how consulting services affect audit quality, from the perspective of knowledge- and expertise-sharing between employees. Semistructured interviews with 16 audit partners reveal that consulting expertise is used in 60–80 percent of audit engagements, with the main rationale for such collaboration being knowledge-sharing and improved audit quality. We leverage a comprehensive office-level dataset of employment profiles covering 86 percent of all employees at large U.S. public accounting firms to systematically investigate the effect of consulting employees on audit quality. We document that a one standard deviation increase in the share of consulting employees in an office results in a 2.6 percentage point reduction in restatements (a decrease of 19 percent relative to the baseline). This effect is strongest when consulting employees have skills complimentary to auditors, e.g., technical and human resources skills, and when consultants have specific industry expertise in the same industry as the audit client. Data Availability: Data from common sources, such as Audit Analytics, can be purchased from the providers. Data on firm-level measures of workforce characteristics and skills are available from the authors upon request, conditional on approval from the data provider (Cognism). JEL Classifications: D22; E24; J24; M42.
