Measuring Wage Inequality Under Right Censoring
There is a growing literature documenting that the persistence of time series may change over time, and as a consequence, shifts in the long-run equilibrium of macroeconomic variables are expected. An important example is the significant increase in public debt in certain periods of time due to increases in government expenditures which are not matched by revenue counterparts. In this paper, new residual-based Wald-type tests are proposed which are designed to detect segmented cointegration, i.e., subsamples during which equilibrium relations exist.
