9 3.Data Description and Empirical Specification 3.1 Data Description In light of our theory discussion of Section 2,the objective of our empirical work is to examine the impact of FDI on economic insecurity.Specifically,we will evaluate how individual self-assessments of economic insecurity correlate with the presence of mobile capital in the form of FDI in the industries in which individuals work.Our data cover Great Britain, which we think is an excellent case to examine both because inward and outward FDI have long figured prominently in the overall economy and because of the high quality of data available The individual data are from the British Household Panel Survey (BHPS)(2001).This survey is a nationally representative sample of more than 5,000 U.K.households and over 9,000 individuals questioned annually from 1991 to 1999.It records detailed information about each respondent's perceptions of economic insecurity,employment,wages,and many other characteristics.The most important pieces of survey information required for our analysis are a measure of economic insecurity,identification of the respondents'industry of employment,and repeated measurement of the same individual over time. We measure economic insecurity by responses to the following question asked in each of the nine years of the panel. "I'm going to read out a list of various aspects of jobs,and after each one I'd like you to tell me from this card which number best describes how satisfied or dissatisfied you are with that particular aspect of your own present job-job security.” 4 The BHPS is ongoing,but our data are through 1999 only.9 3.
