· Study Name: Korea Labor and Income Panel Study (KLIPS)

 

· Study Director: Dr. Kilsang Yoo

 

· Principal Investigators: Dr. Hanam Phang, Dr. Joyup Ahn, Dr. Jiyeon Chang

 

· Host Organization: Employment Research Center, Korea Labor Institute

 

· Year Initiated: 1998

 

· Governance

 

-          Funding Sources: The Ministry of Labor funds the activities of KLIPS out of the Employment Insurance Fund

-          Host Organization: This study is conducted by the Employment Research Center, KLI

-          Governing body and role of external research advisors: Formal governing body is the Project Management Committee (internal) seated by the President, Vice-President, and Directors of the KLI. External research advisory group is consisted mainly of scholars from academia in various fields (economics, sociology, survey method and statistics). They consult the panel team on questionnaire development, data analysis, and methodology.

 

· Sample Design

 

-          Sample Selection: The KLIPS sample is an equal probability sample of households from the 7 metropolitan cities and urban areas in 8 provinces (excluding Cheju Ireland) and was designated to yield 5000 households and their members (aged 15 and over) interviewed. The final number of individuals that we succeeded to finish 1^st-round interviewing amounted to 13,317 in 1998. These 5000 households and their members make the original panel households and household members. To sample primary sampling units and then household therein KLIPS used the sampling frame for the 1995 Korean (mid-term) census. Out of the census unit area (total = 21,938), total 951 sampling unit areas are finally selected and from each sampling unit, 5-6 households are randomly selected. The households and their members thus selected are designed to represent the adult population (aged 15 and over) residing in urban areas.

 

 

-          Follow Rules: The individuals that have blood and economic ties to the original panel members are added to the original sample since the 2^nd wave (1999). For example, if a panel member gets married and forms an independent household with his/her spouse, then, his/her spouse becomes a “new joiner” to the original panel and the couple is followed and is interviewed thereafter. In the opposite way, if one of our panel member moves into non-member household, on getting married for instance, he/she is also followed and his/her spouse’s household members are interviewed. In this way, the size of our sample members gets expanded over the waves. This way of incorporating related households and individuals into the sample is to let the expanded sample reflect on-going demographic dynamics of our original panel members. And when a panel member moves out of the original household, on divorce for instance, he/she is also followed as long as he/she lives with his/her children.

 

-          Oversampling: No oversampling currently. But in the future, might be considered (esp. to let more irregular workers in)

 

-          Weights and Attrition Bias: The sample is re-weighted every wave

-          Sample “refreshing”: We will evaluate sample attrition rate and patterns after the 3^rd wave and decide whether or not replacement of the dropped members be done

 

· Content

 

-          Driving policy needs: current and long-term labor-related and labor market issues, especially labor market dynamics and family economy

 

-          Research objectives: to explore employment and unemployment structure, family economy, and individual labor market performance

 

-          International comparisons: possible in many aspects (representative sample, labor force, questions) and survey items (esp. trying to replicate NLSY)

 

-          Content decisions: schooling and labor market transitions, working conditions and wage, childcare and investment in education, schooling history, socioeconomic background, family economy

 

-          Tradeoffs between continuity and the incentives for new directions

 

· Collection

 

-          Mode: The KLIPS is collected in face-to-face interviews using paper and pencil questionnaires. If face-to-face interview is not feasible, then, the questionnaire is left behind so that the designated individual self-report the questionnaire. We are planning to introduce CAPI from the 5^th wave (2002).

 

-          Instrument design (paper and pencil)

-          Dependent interviewing: None

-          Calendar year, survey year and point of survey measures: some of each (ex, household income = calendar year; employment and working conditions = point of survey)

 

· Processing

 

-          Jobs data is constructed out of 3 waves of survey data

-          Schooling and work history data will be produced

 

· Dissemination

 

-          Dissemination techniques (CD, Web): The 1^st and 2^nd wave data sets are available in CD (in ASCII, SPSS, SAS format) on charge through KLI (panel team). 20% sample data can be downloaded from the KLIPS web site. Codebooks and users’ guide are also available for each wave.

 

-          Improving contractual use of data (confidentiality and encryption): yes

 

-          Comparability of formats (evolution of data standards): Data are disseminated in ASCII, SPSS, and SAS format

 

-          Value of joint multinational analysis projects: highly valued
