Time-series tools are often employed in competition law investigations to detect collusion, estimate damages and study post-merger market outcomes. Time-series data (including panel data) are also often employed in empirical industrial organisation (IO) models to estimate demand function and simulate mergers, as well as to delineate markets. To advance research in each of these subfields and to contribute to greater integration of the various fields, Stellenbosch University, is organising a workshop on 4-5 March 2013. The workshop, funded by Economic Research Southern Africa (ERSA), will offer researchers across South Africa and beyond to build networks and present current research involving time-series applications to competition policy problems.
