Popis: | We outline a procedure for unifying various cross sections of the German Sample Survey of Income and Expenditure in a pooled database, and discuss potential pitfalls of such a venture. Particularly, we investigate the consequences of a major break in the survey design for inter-temporal comparability of expenditure distributions: a reduction of the surveying period from twelve to three month taking place between the census years 1993 and 1998. We demonstrate that the shortened survey period impacts the commodity-specific expenditure distributions differently, and that different commodity-specific purchase frequencies are a likely explanation. Moreover, we suggest and empirically assess the suitability of several conversion procedures to ensure comparability of the expenditure distributions before and after the shortening of the surveying period. |
