摘要

摘要本文研究了从网络爬行中获得的空缺人口与国家统计局（NSO）使用传统方法推断的经济空缺之间的关系。我们比较了荷兰统计局和一家网络抓取公司在2007年至2014年间获得的样本的时间序列特性。我们发现，网络和NSO空缺数据呈现出相似的时间序列特性，这表明两个时间序列都是由相同的潜在现象产生的：经济中新空缺的真实数量。我们的结论是，在我们的案例研究中，网络数据能够捕捉劳动力市场的总体经济活动。

Survey vs Scraped Data: Comparing Time Series Properties of Web and Survey Vacancy Data

Abstract This paper studies the relationship between a vacancy population obtained from web crawling and vacancies in the economy inferred by a National Statistics Office (NSO) using a traditional method. We compare the time series properties of samples obtained between 2007 and 2014 by Statistics Netherlands and by a web scraping company. We find that the web and NSO vacancy data present similar time series properties, suggesting that both time series are generated by the same underlying phenomenon: the real number of new vacancies in the economy. We conclude that, in our case study, web-sourced data are able to capture aggregate economic activity in the labor market.

期刊介绍： As of March 31, 2019, the IZA Open Access Journal Series will transfer to Sciendo. Please use the Springer Editorial Manager system for all submissions until February 28. During the transfer period in March 2019 you may direct your submissions to journals@iza.org. The IZA Journal of Labor Economics publishes scientific articles in all areas of labor economics. This refers to original high-quality theoretical and applied contributions on both microeconomic and macroeconomic labor-related topics. In particular, the IZA Journal of Labor Economics encourages submissions in subject areas that are closely linked to the various IZA Program Areas, ranging from education, family and environment to mobility, behavioral and personnel economics, and labor market institutions, among others. The IZA Journal of Labor Economics is part of IZA’s mission of contributing to social and economic discourse, enabling political decision-making to be based on the best available scientific knowledge. We want to stimulate research to close knowledge gaps. Hence, the IZA Journal of Labor Economics particularly welcomes contributions that provide scientifically sound answers to open and relevant questions of modern labor economics.
