Indicators of Product Sophistication and Factor Intensities: Measurement Matters
The widely used PRODY indicator by Hausmann et al. (J Econ Growth 12(1):1–25, 2007) allows the calculation of product sophistication and factor intensities at high levels of disaggregation. In this chapter I deal with its measurement, its conceptional limitations, its sensitivity to subjective decision making, its alternatives, and how to reap the best possible benefit from its usage. I introduce a theory-based alternative and investigate the sensitivity of empirical results with respect to different measures. In particular, I re-estimate the main results of Hausmann et al. (J Econ Growth 12(1):1–25, 2007) with 75 different measures. Small changes to the sample, the aggregation level, or the construction of the indicator can make a difference. Moreover, I offer two Stata programs that ease the calculation of various PRODY variants.
期刊介绍：
The Journal of Economic and Social Measurement (JESM) is a quarterly journal that is concerned with the investigation of all aspects of production, distribution and use of economic and other societal statistical data, and with the use of computers in that context. JESM publishes articles that consider the statistical methodology of economic and social science measurements. It is concerned with the methods and problems of data distribution, including the design and implementation of data base systems and, more generally, computer software and hardware for distributing and accessing statistical data files. Its focus on computer software also includes the valuation of algorithms and their implementation, assessing the degree to which particular algorithms may yield more or less accurate computed results. It addresses the technical and even legal problems of the collection and use of data, legislation and administrative actions affecting government produced or distributed data files, and similar topics. The journal serves as a forum for the exchange of information and views between data producers and users. In addition, it considers the various uses to which statistical data may be put, particularly to the degree that these uses illustrate or affect the properties of the data. The data considered in JESM are usually economic or social, as mentioned, but this is not a requirement; the editorial policies of JESM do not place a priori restrictions upon the data that might be considered within individual articles. Furthermore, there are no limitations concerning the source of the data.
