Panel Data in Research on Mobility and Migration: A Review of Recent Advances	2021	28	.pdf	application/pdf	13176	581	31	With panel data, truncation bias in spatial mobility studies is minimised as the prospective design enables mobile individuals to be followed over time. The fact that mobile individuals are also selected on unobservables (or factors that are diffi cult to measure, such as ability, personal traits, or motivation) is problematic because it induces individual unobserved heterogeneity in spatial mobility models and limits the ability of researchers to obtain unbiased estimates.	cache/cpos-441.pdf	txt/cpos-441.txt
