1993-2000 The Survey of Labor and Income Dynamics (SLID) is a longitudinal household survey designed to follow the same respondents for several years. The sample is approximately 35,000 households located throughout all ten provinces. The survey gathers information on the economic well-being of individuals and families, and the changes that influence this well-being. SLID also collects information about other related topics such as education and disabilities. http://www.statcan.ca/english/survey/household/dynamic/income.htm Panel Study of Income Dynamics (PSID) Institute for Social Research at the University of Michigan 1968The Panel Study of Income Dynamics (PSID), is a longitudinal study of a representative sample of U.S. individuals and the family units in which they reside. Sample size has grown from 4,800 in 1968 to 6,434 in 1999. Core topics: Income sources and amounts, poverty status, public assistance in the form of food or housing, other financial matters (e.g., taxes, inter-household transfers), family structure and demographic measures, labor market work, housework time, housing, geographic mobility, socio-economic background, and health. Other supplemental topics: housing and neighborhood characteristics, achievement motivation, estimating risk tolerance, child care, child support, and child development, job training and job acquisition, retirement plans, health, kinship, wealth, education, military combat experience, risk tolerance, immigration history, and time use. http://www.isr.umich.edu/src/psid/index.html

National Longitudinal Survey (NLS) Census Bureau and the Center for Human Resource Research (CHRR) at Ohio State University 1966The first set of surveys, initiated in 1966, consisted of four cohorts. These four groups are referred to as the "older men," "mature women," "young men," and "young women" cohorts of the NLS, and are known collectively as the "original cohorts." In 1979, a longitudinal study of a cohort of young men and women aged 14 to 22 was begun. This sample of youth was called the National Longitudinal Survey of Youth 1979 (NLSY79). In 1986, the NLSY79 was expanded to include surveys of the children born to women in that cohort and called the NLSY79 Children. In 1997, the NLS program was again expanded with a new cohort of young people aged 12 to 16 as of December 31, 1996. This new cohort is the National Longitudinal Survey of Youth 1997 (NLSY97). Surveys include data about a wide range of events such as schooling and career transitions, marriage and fertility, training investments, child-care usage, and drug and alcohol use. The depth and breadth of each survey allow for analysis of an expansive variety of topics such as the transition from school to work, job mobility, youth unemployment, educational attainment and the returns to education, welfare recipiency, the impact of training, and retirement decisions. http://www.bls.gov/nls/ Chinese Longitudinal Healthy Longevity Survey (CLHLS) National Archive of Computerized Data on Aging (NACDA) 1998-2000 The largest sample size of centenarians and nonagenarians as compared to any other studies focusing on elders in the world, CLHLS was conducted among the most elderly population in counties and cities of 22 provences of China with the general goal of shedding light on the determinants of healthy human longevity and oldest-old mortality. Data are provided on the health, socioeconomic characteristics, family, lifestyle, and demographic profile of this aged population. NACDA seeks to contribute to the intellectual vitality of the gerontological sciences. http://www.icpsr.umich.edu/NACDA/archive.html

1.3. benefits and limitations of panel data a) controlling for individual heterogeneity b) panel data give more informative data, more variability, less collinearity among the variables, more degrees of freedom and more efficiency c) panel data are better able to study the dynamics of adjustment d) panel data are better able to identify and measure effects that are simply not detectable in pure cross-section or pure time-series data e) panel data models allow one to construct and test more complicated behavioral models than purely cross-section or time series data f) panel data are usually gathered on micro units, like individuals, firms and households g) design and data collection problems h) distortions of measurement errors i) self-selectivity problems j) nonresponse k) attrition l) short time-series dimension
