| Abstract | Multi-sourcing is a common procurement practice, especially for key products with low total costs because of risk considerations. In this context often split award auctions are applied. We develop two different descending split award auctions where the auctioneer buys a bundle of four different products. Each of the items is bought through two lots each with different sizes to different bidders. Firstly, we set up these auction formats in an iterative setting and find that the communication complexity differs significantly. One format is the Reverse Combinatorial Clock (RCC) auction. Combinatorial auctions have been suggested as a mean to raise efficiency in multi-item negotiations with complementarities among goods as they can be found in procurement, energy markets, transportation and the sale of spectrum auctions. The second format is the simultaneous Yankee auction (SY) which is a variation of the simultaneous multi-round auction (SMRA). We perform simulations in different treatments and find out that the RCC results in a better efficiency and auctioneer costs in most cases, especially using a combination of straight forward and power set bidding strategies. We conclude, that even in environments with complementarities an efficient bidding language using the right auction format and rules, as the configuration of our SY auction, can result in almost as efficient outcomes as a combinatorial auction with the advantage of being computational tractable. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
