We assume that there are two heterogeneous objects and two bidders, and that each bidder does not know the other bidder\u2019s material payoff structure. We conducted the laboratory experiments for eight payoff structures associated with complements and substitutes. We compare three types of auction formats, i.e., sequential first price auction, clock auction, and VCG mechanism. We also research questionnaires concerning the subjects\u2019 impressions about the performance of these formats. The experimental results imply that the VCG mechanisms generally function very well, while the performance of the clock auctions is pretty bad in some cases. These observations are in contrast with the results of the questionnaires.", "subitem_description_type": "Abstract"}]}, "item_4_description_6": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u8ad6\u6587/Article", "subitem_description_type": "Other"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "26682", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Matsushima, Hitoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "26683", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Teruyama, Hiroshi"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/00016789", "subitem_identifier_reg_type": "JaLC"}]}, "item_4_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5927\u5b66\u7d4c\u6e08\u5b66\u4f1a"}]}, "item_4_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00070411", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0022-9768", "subitem_source_identifier_type": "ISSN"}]}, "item_4_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "The Society of Economics, The University of Tokyo"}]}, "item_4_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u6771\u4eac\u5927\u5b66\u5927\u5b66\u9662\u7d4c\u6e08\u5b66\u7814\u7a76\u79d1"}, {"subitem_text_value": "\u4eac\u90fd\u5927\u5b66\u7d4c\u6e08\u7814\u7a76\u6240"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u677e\u5cf6, \u6589"}], "nameIdentifiers": [{"nameIdentifier": "26680", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u7167\u5c71, \u535a\u53f8"}], "nameIdentifiers": [{"nameIdentifier": "26681", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-08"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "econ0790103.pdf", "filesize": [{"value": "877.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 877300.0, "url": {"label": "econ0790103.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/16798/files/econ0790103.pdf"}, "version_id": "eb3226cc-05c2-4db2-9493-bed69ee8b13a"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u8907\u6570\u7a2e\u8ca1\u53d6\u5f15\u306e\u30aa\u30fc\u30af\u30b7\u30e7\u30f3\u306b\u3064\u3044\u3066\u306e\u7d4c\u6e08\u5b66\u5b9f\u9a13 : \u9010\u6b21\u4e00\u4f4d\u4fa1\u683c\u5165\u672d\uff0c\u6642\u8a08\u5165\u672d\uff0cVCG \u30e1\u30ab\u30cb\u30ba\u30e0\u306e\u6bd4\u8f03\u5206\u6790", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u8907\u6570\u7a2e\u8ca1\u53d6\u5f15\u306e\u30aa\u30fc\u30af\u30b7\u30e7\u30f3\u306b\u3064\u3044\u3066\u306e\u7d4c\u6e08\u5b66\u5b9f\u9a13 : \u9010\u6b21\u4e00\u4f4d\u4fa1\u683c\u5165\u672d\uff0c\u6642\u8a08\u5165\u672d\uff0cVCG \u30e1\u30ab\u30cb\u30ba\u30e0\u306e\u6bd4\u8f03\u5206\u6790"}]}, "item_type_id": "4", "owner": "1", "path": ["62/828/844/852", "9/504/831/846/853"], "permalink_uri": "https://doi.org/10.15083/00016789", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2014-10-30"}, "publish_date": "2014-10-30", "publish_status": "0", "recid": "16798", "relation": {}, "relation_version_is_last": true, "title": ["\u8907\u6570\u7a2e\u8ca1\u53d6\u5f15\u306e\u30aa\u30fc\u30af\u30b7\u30e7\u30f3\u306b\u3064\u3044\u3066\u306e\u7d4c\u6e08\u5b66\u5b9f\u9a13 : \u9010\u6b21\u4e00\u4f4d\u4fa1\u683c\u5165\u672d\uff0c\u6642\u8a08\u5165\u672d\uff0cVCG \u30e1\u30ab\u30cb\u30ba\u30e0\u306e\u6bd4\u8f03\u5206\u6790"], "weko_shared_id": null}
