While most of the literature on measurement error focuses on additive measurement error, we consider in this paper the multiplicative case. We apply the Simulation Extrapolation method (SIMEX)-a procedure which was originally proposed by Cook and Stefanski (J. Am. Stat. Assoc. 89:1314Assoc. 89: -1328Assoc. 89: , 1994 in order to correct the bias due to additive measurement error-to the case where data are perturbed by multiplicative noise and present several approaches to account for multiplicative noise in the SIMEX procedure. Furthermore, we analyze how well these approaches reduce the bias caused by multiplicative perturbation. Using a binary probit model, we produce Monte Carlo evidence on how the reduction of data quality can be minimized.

Abstract Whereas the literature on additive measurement error has known a considerable treatment, less work has been done for multiplicative noise. In this paper we concentrate on multiplicative measurement error in the covariates, which contrary to additive error not only modifies proportionally the original value, but also conserves the structural zeros. Terms of use: Documents inThis paper compares three variants to specify the multiplicative measurement error model in the simulation step of the Simulation-Extrapolation (SIMEX) method originally proposed by Cook and Stefanski (1994): i) as an additive one without using a logarithmic transformation, ii) as the well-known logarithmic transformation of the multiplicative error model, and iii) as an approach using the multiplicative measurement error model as such. The aim of the paper is to analyze how well these three approaches reduce the bias caused by the multiplicative measurement error. We apply three variants to the case of data masking by multiplicative measurement error, in order to obtain parameter estimates of the true data generating process. We produce Monte Carlo evidence on how the reduction of data quality can be minimized.JEL classification: C13, C21

In the project "Combined firm data for Germany" (KombiFiD) firm data from different institutions were merged and made available for research for the first time. The institutions involved in the project faced considerable challenges both due to the narrow legal limits underlying such a merging procedure and as a result of the partial lack of a unique identifier. This paper provides an overview of the objectives associated with the project and its progress.
