Analyse the relationship between unemployment and crime.
www.essex.ac.ukunemployment and crime is the potential endogeneity problem. Endogeneity may arise from both omitted variable bias and reverse causality. This is because both unemployment and crime are jointly determined i.e. a rise in unemployment can lead to a rise in crime and likewise an individual who commits a crime results in being unemployed.

econ.lse.ac.ukcreated an endogeneity problem instead. Note, however, that this regression is still useful because and y are negatively correlated so that d1= is biased downwards, implying an upward bias for b r = 1= 1d= . Thus the results from the standard regression and from the reverse regression will bracket the true coe¢ cient, i.e. plim b < < plim b r
