Current school finance problems are discussed in three papers. The first presents an analysis of the Illinois school finance reform law, providing insights into the operation of the law and an evaluation method for examining finance laws in other states. In the second paper, the relationships between selected features of Michigan school districts that can explain some interdistrict cost differences are explored. An index measures price differences among school districts, and a first attempt is made to go beyond a simple cost-of-living index to adjust for district cost differences associated with location. The third paper explores special urban aid factors in state school aid formulas for selected cities with municipal overburdens. The effects of tax exporting on local taxes, urban school aid factors, and tax burdens of various school finance reforms are analyzed. The final section describes New Mexico, Georgia, and Kentucky school finance reform laws. (Author/DW)
