This dissertation pursues to find an answer empirically to the question of the revenue ranking between the multiple price auction and the single price auction. I also attempt to get empirical clues in terms of the efficiency ranking between the two. Under the assumptions of symmetric bidders and private independent value (PIV), I derive the optimal bidding conditions for both auction formats. Following the structural model estimation approach, I estimate the underlying distribution of market clearing price using the nonparametric resampling strategy and recover the bidders’ unknown true valuations corresponding to each observed bid point. With these estimated valuations of the bidders, I calculate what the upper bound of the revenue would have been under the Vickery auction to perform the counterfactual revenue comparison with the actual revenue. I find that, ex-post, the multiple price auction yields more revenue to the Korean Treasury than the alternative. I also investigate the efficiency ranking by comparing the number of bids switched and the amount of surplus change which would occur when the bidders are assumed to report their true valuations as their bids. I find that the multiple price auction is also superior to the alternative in efficiency which supports the current theoretical prediction. Finally, I investigate the robustness of my model and empirical results by relaxing the previous assumptions. I, first, extend the model and estimation to the case of asymmetric bidders where the bidders are divided into two groups based on their size. It shows that the model and estimation framework are still valid and that the empirical findings are very similar to the symmetric case. I also test for the presence of common value (CV) component in the bidders’ valuation function. I propose the simple regression model adopting the idea of the policy experimental approach. I obtain quite an inconclusive result in general but find some evidence supporting PIV for relatively higher bid prices while supporting CV for lower bid prices.

Summaries in Afrikaans and English / Text in Afrikaans / In the recent decision in Kellerman v South African Transport Services 1993 4 SA 872 (C) a claim for the loss of the use of a thing not utilised in the production of income was apparently allowed for the first time in South African law. A number of strict requirements were however set for such a claim. For a considerable time a claim has been recognised in English and German law even where a substitute was not hired and where the article was used for pleasure purposes. It is submitted that this should also be the position in South African law because the loss of the use of a thing per se has an independent value. It is further submitted that the interest on capital value method (as per English law) can be used as starting-point in the determination of quantum. A degree of flexibility is necessary to ensure fairness and equity. / In die onlangse beslissing in Kellerman v South African Transport Services 1993 4 SA 872 (K) is daar klaarblyklik die eerste maal in die Suid-Afrikaanse reg 'n eis om skadevergoeding weens gebruiksverlies van 'n saak wat nie in die produksie van inkomste gebruik is nie erken. Die hof stel egter 'n aantal streng vereistes vir so 'n eis. 'n Eis word al 'n geruime tyd in die Engelse en Duitse reg erken selfs waar 'n substituut nie gehuur is nie en waar sake bloot vir plesierdoeleindes gebruik is. Daar word submitteer dat dit ook die posisie in die Suid-Afrikaanse reg behoort te wees aangesien gebruiksverlies opsigself 'n selfstandige waarde het. Dit word verder aangevoer dat die rente-op-kapitaalwaarde-metode (soos in die Engelse reg) gebruik kan word as 'n uitgangspunt by kwantumbepaling.
