In our framework, a person\u2019s self-esteem is determined by sampling his memories of ego-relevant outcomes in a fashion that in turn depends on how he feels about himself, potentially creating multiple fragile \u201cself-esteem personal equilibria.\u201d Self-esteem is especially likely to be fragile, as well as unrealistic in either the positive or the negative direction, if being successful is important to the agent. A person with a low self-view might exert less effort when success is more important. An individual with a high self-view, in contrast, might distort his choices to prevent a collapse in self-esteem, with the distortion being greater if his true ability is lower. We discuss the implications of our results for mental well-being, education, job search, workaholism, and aggression.<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>Takeshi Murooka\u3000<\/strong>coauthored with Takuro Yamashita \uff08Discussion Paper\uff09<br \/>\n&#8220;Optimal Trade Mechanisms with Adverse Selection and Inferential Mistakes&#8221; <br \/>\n<a href=\"https:\/\/www.osipp.osaka-u.ac.jp\/archives\/DP\/2021\/DP2021E006.pdf\">OSIPP DP-2021-E-006<\/a>(September 2021)<\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">Abstract: We study an adverse selection environment, where a rational seller can trade a good of which she privately knows its value to a buyer, and there are gains from trade. The buyer&#8217;s types differ in their degree of inferential abilities: A rational type correctly infers the value of the good from the seller&#8217;s offer, whereas a naive type under-appreciates the correlation between the seller&#8217;s private information and offer. We characterize the optimal menu mechanism that maximizes the social surplus. Notably, no matter how severe the adverse selection is (in particular, even when no trade is the unique possible outcome if all agents are rational), all types of buyers trade in the optimal mechanism. The rational buyer&#8217;s trade occurs at the expense of the naive buyer&#8217;s losses. We also investigate a consumer-protection policy of limiting the losses and discuss its implications.<\/p>\n<p>&nbsp;<\/p>\n<blockquote><p><strong>\u8d64\u4e95\u4f38\u90ce<\/strong>\uff08\u305d\u306e\u4ed6\u306e\u8a18\u4e8b\uff09<br \/>\n\u300c\u6301\u7d9a\u53ef\u80fd\u306a\u5730\u65b9\u8ca1\u653f\u6167\u904b\u55b6\u306b\u5411\u3051\u305f\u30ac\u30d0\u30ca\u30f3\u30b9\u300d\u300e\u5730\u65b9\u8ca1\u653f\u300fNo.721\u30012021\u5e748\u6708\u53f7\u3000p4-14(8\u6708\u767a\u884c\uff09<\/p><\/blockquote>\n<p style=\"padding-left: 10px;\">\u6982\u8981\uff1a\u904e\u53bb10\u5e74\u306b\u304a\u3051\u308b\u5730\u65b9\u8ca1\u653f\u5236\u5ea6\u306e\u81ea\u6cbb\u4f53\u3078\u306e\u30ac\u30d0\u30ca\u30f3\u30b9\u52b9\u679c\u3068\u6b8b\u3055\u308c\u305f\u8ab2\u984c\u3092\u6574\u7406\u3057\u3001\u30b3\u30ed\u30ca\u798d\u306b\u304a\u3051\u308b\u30b3\u30ed\u30ca\u5bfe\u5fdc\u3078\u306e\u30ac\u30d0\u30ca\u30f3\u30b9\u3068\u3001\u4eca\u5f8c\u306e\u30ac\u30d0\u30ca\u30f3\u30b9\u306e\u5728\u308a\u65b9\u306b\u3064\u3044\u3066\u691c\u8a0e\u3057\u3066\u3044\u308b\u3002\u30b3\u30ed\u30ca\u5bfe\u5fdc\u306f\u3082\u3061\u308d\u3093\u3067\u3042\u308b\u304c\u3001\u8ca1\u653f\u518d\u5efa\u5316\u3084\u8001\u673d\u5316\u7b49\u306b\u5bfe\u3057\u9577\u671f\u7684\u8996\u91ce\u3092\u6301\u3061\u3001\u91cd\u8981\u6027\u3092\u8a8d\u8b58\u3057\u3001\u4eca\u3059\u3050\u306b\u3067\u3082\u3067\u304d\u308b\u5bfe\u7b56\u304b\u3089\u59cb\u3081\u308b\u3053\u3068\u3092\u63d0\u6848\u3057\u3066\u3044\u308b\u3002<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>\u5ba4\u5ca1\u5065\u5fd7<\/strong>\uff08\u305d\u306e\u4ed6\u306e\u8a18\u4e8b\uff09<br \/>\n\u300c\u5ea7\u8ac7\u4f1a\uff1a\u6d88\u8cbb\u8005\u6cd5\u306e\u6539\u6b63\u52d5\u5411\u3092\u8ad6\u3058\u308b\u300d\u300e<a href=\"https:\/\/www.nippyo.co.jp\/shop\/magazine\/8606.html\">\u6cd5\u5f8b\u6642\u5831<\/a>\u300f2021\u5e749\u6708\u53f7\uff087\u670827\u65e5\u767a\u58f2\uff09<\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">\u6982\u8981\uff1a\u96a3\u63a5\u8af8\u79d1\u5b66\u3001\u3068\u304f\u306b\u7d4c\u6e08\u5b66\u3001\u884c\u52d5\u7d4c\u6e08\u5b66\u3001\u5fc3\u7406\u5b66\u3068\u6cd5\u5b66\u3068\u306e\u5354\u50cd\u3068\u3044\u3046\u8996\u70b9\u304b\u3089\u3001\u8fd1\u6642\u306e\u6d88\u8cbb\u8005\u6cd5\u306e\u7acb\u6cd5\u30fb\u6cd5\u6539\u6b63\u52d5\u5411\u306e\u4e2d\u304b\u3089\u3044\u304f\u3064\u304b\u306e\u30c8\u30d4\u30c3\u30af\u3092\u53d6\u308a\u4e0a\u3052\u3001\u5ea7\u8ac7\u4f1a\u65b9\u5f0f\u3067\u8b70\u8ad6\u3057\u305f\u3002<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>\u4e8c\u6749\u5065\u6597<\/strong>\uff08\u305d\u306e\u4ed6\u306e\u8a18\u4e8b\uff09<\/p>\n<p>\u300cICSID\u306b\u3088\u308b\u6295\u8cc7\u7d1b\u4e89\u89e3\u6c7a\uff0dEDF International S.A.\u307b\u304b\u4e8b\u4ef6\u300d\u68ee\u5ddd\u5e78\u4e00\u307b\u304b\uff08\u7de8\uff09<br \/>\n\u300e<a href=\"http:\/\/www.yuhikaku.co.jp\/books\/detail\/9784641115552\">\u56fd\u969b\u6cd5\u5224\u4f8b\u767e\u9078\u3014\u7b2c3\u7248\u3015<\/a>\u300f\uff08\u6709\u6590\u95a3\u30012021\u5e74\uff09186-187\u9801<\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">\u6982\u8981\uff1a\u672c\u7a3f\u306f\u3001\u5224\u4f8b\u6559\u6750\u300e\u56fd\u969b\u6cd5\u5224\u4f8b\u767e\u9078\u300f\u306e\u65b0\u7248\u306b\u63b2\u8f09\u3055\u308c\u305f\u5224\u4f8b\u89e3\u8aac\u3067\u3042\u308b\u3002\u300c\u56fd\u969b\u7d1b\u4e89\u51e6\u7406\u65b9\u5f0f\u300d\u306b\u95a2\u3059\u308b13\u7ae0\u672b\u306b\u7f6e\u304b\u308c\u305f\u672c\u7a3f\u3067\u306f\u3001\u6295\u8cc7\u7d1b\u4e89\u89e3\u6c7a\u56fd\u969b\u30bb\u30f3\u30bf\u30fc\uff08ICSID\uff09\u306b\u304a\u3051\u308b\u5916\u56fd\u6295\u8cc7\u5bb6\u3068\u6295\u8cc7\u53d7\u5165\u56fd\u3068\u306e\u9593\u3067\u306e\u7d1b\u4e89\u89e3\u6c7a\u65b9\u5f0f\u306e\u7279\u5fb4\u3092\u3001\u4ef2\u88c1\u4eba\u306e\u4e0d\u504f\u6027\u306e\u6b20\u5982\u7b49\u3092\u7406\u7531\u306b\u4ef2\u88c1\u5224\u65ad\u306e\u53d6\u6d88\u3057\u304c\u4e89\u308f\u308c\u305fEDF International\u307b\u304b\u5bfe\u30a2\u30eb\u30bc\u30f3\u30c1\u30f3\u4e8b\u4ef6\u3092\u984c\u6750\u3068\u3057\u3066\u89e3\u8aac\u3057\u3066\u3044\u308b\u3002<\/p>\n","protected":false},"excerpt":{"rendered":"<p>OSIPP\u57fa\u5e79\u8b1b\u5ea7\u6559\u54e1\u306e9\u6708\u306e\u7814\u7a76\u696d\u7e3e\u3092\u3054\u7d39\u4ecb\u3057\u307e\u3059\u3002 \u30fb\u5ba4\u5ca1\u5065\u5fd7\u5148\u751f \u30fb\u8d64\u4e95\u4f38\u90ce\u5148\u751f \u30fb\u4e8c\u6749\u5065\u6597\u5148\u751f &nbsp;
