We use data tracking mothers&#8217; employment status after childbirth, merging administrative data on the availability of both standard and nonstandard childcare centres. This is linked to each respondent via location identifiers based on their residential city and the nearest train station. The findings first show that an increase in unlicensed\/nonstandard daycare availability significantly raised the proportion of mothers who return to work by the time the child reaches the age of three, particularly in areas with limited access to licensed\/standard centres. Secondly, the effects may vary depending on the services offered by the centres. The results suggest that nonstandard centres, often more conveniently located and offering varied services, better meet the needs of working mothers, leading to higher employment rates. This research emphasizes that government efforts to expand childcare options in the 2010s may play a crucial role in promoting maternal labour\u2010force participation in Japan.<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>Takuro Yamashita <\/strong>\uff08\u8ad6\u6587\uff09<\/p>\n<p>Daniil Larionov, Hien Pham, Takuro Yamashita, Shuguang Zhu, &#8220;First Best Implementation With Costly Information Acquisition&#8221;, <em> Journal of Economics &amp; Management Strategy,<\/em>First published: 29 January 2025\uff08\u67fb\u8aad\u3042\u308a\uff09<a href=\"https:\/\/doi.org\/10.1111\/jems.12628\">https:\/\/doi.org\/10.1111\/jems.12628<\/a><\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">Abstract: We study mechanism design with flexible but costly information acquisition. There is one principal and four or more agents, who share a common prior belief over a set of payoff-relevant states. The principal proposes a mechanism to the agents, each of whom can then acquire information about the state by privately designing a signal device. As long as it is costless for each agent to acquire a signal that is independent of the state, there exists a mechanism that allows the principal to implement any social choice rule at zero information acquisition cost for the agents.<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>\u5927\u4e45\u4fdd\u90a6\u5f66<\/strong>\uff08\u8ad6\u6587\uff09<\/p>\n<p>\u300c\u76f8\u7d9a\u306e\u6839\u62e0\u300d\u300e\u962a\u5927\u6cd5\u5b66\u300f\u7b2c74\u5dfb\u7b2c5\u53f7\uff082025\u5e741\u6708\uff09<a href=\"https:\/\/doi.org\/10.18910\/100307\">https:\/\/doi.org\/10.18910\/100307<\/a><\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">\u6982\u8981\uff1a\u672c\u7a3f\u3067\u306f\u3001\u300c\u76f8\u7d9a\u306e\u6839\u62e0\u300d\u300c\u76f8\u7d9a\u5236\u5ea6\u306e\u5fc5\u8981\u6027\u300d\u3068\u3044\u3046\u9805\u76ee\u306e\u4e0b\u3067\u8ad6\u3058\u3089\u308c\u308b\u8af8\u554f\u984c\u306b\u691c\u8a0e\u3092\u52a0\u3048\u3001\u76f8\u7d9a\u5236\u5ea6\u306e\u80cc\u5f8c\u306b\u63a7\u3048\u3066\u3044\u308b\u6cd5\u539f\u7406\u3092\u660e\u3089\u304b\u306b\u3057\u3088\u3046\u3068\u8a66\u307f\u305f\u3002\u6700\u521d\u306b\u3001\u76f8\u7d9a\u5236\u5ea6\u5426\u5b9a\u8ad6\u3068\u3057\u3066\u3001\u30bd\u30d3\u30a8\u30c8\u306b\u304a\u3051\u308b\u76f8\u7d9a\u5ec3\u6b62\u306e\u793e\u4f1a\u5b9f\u9a13\uff08\u76f8\u7d9a\u5ec3\u6b62\u5e03\u544a\uff09\u3001\u6cd5\u54f2\u5b66\u8005\u30fb\u68ee\u6751\u9032\u306e\u898b\u89e3\u3001\u54f2\u5b66\u8005\u30fb\u30cf\u30ba\u30ec\u30c3\u30c8\u306e\u898b\u89e3\u306b\u691c\u8a0e\u3092\u52a0\u3048\u3001\u6b21\u306b\u3001\u300c\u76f8\u7d9a\u306e\u6839\u62e0\u300d\u306b\u95a2\u3059\u308b\u5f93\u524d\u306e\u5b66\u8aac\uff08\u610f\u601d\u8aac\u30fb\u6e05\u7b97\u8aac\u30fb\u6276\u990a\u8aac\u30fb\u53d6\u5f15\u5b89\u5168\u8aac\u30fb\u516c\u76ca\u8aac\uff09\u3092\u6982\u89b3\u3057\u305f\u3002\u4ee5\u4e0a\u306e\u8003\u5bdf\u3092\u8e0f\u307e\u3048\u3001\u76f8\u7d9a\u5236\u5ea6\u3092\u5426\u5b9a\u3057\u305f\u5834\u5408\u306b\u3069\u3046\u306a\u308b\u304b\u306b\u3064\u3044\u3066\u3001\u7a4d\u6975\u8ca1\u7523\u3068\u6d88\u6975\u8ca1\u7523\u306b\u5206\u3051\u3066\u601d\u8003\u5b9f\u9a13\u3092\u884c\u3063\u305f\u3002\u305d\u306e\u7d50\u679c\u3001\u76f8\u7d9a\u5236\u5ea6\u306e\u5ec3\u6b62\u306f\u5f0a\u5bb3\u304c\u5927\u304d\u304f\u3001\u73fe\u5b9f\u7684\u306a\u9078\u629e\u80a2\u3068\u3057\u3066\u306f\u63a1\u308a\u3048\u306a\u3044\u3068\u3044\u3046\u7d50\u8ad6\u306b\u9054\u3057\u305f\u3002\u7d50\u8ad6\u7684\u306b\u306f\u3001\u672c\u7a3f\u306f\u3001\u76f8\u7d9a\u6cd5\u306e\u4e3b\u76ee\u7684\u3092\u3001\u53d6\u5f15\u5b89\u5168\u306e\u305f\u3081\u306b\u907a\u7523\u7ba1\u7406\u6a5f\u69cb\u3092\u8a2d\u7f6e\u3059\u308b\u3053\u3068\u306b\u6c42\u3081\u3066\u3044\u308b\u304c\u3001\u5f93\u524d\u306e\u5b66\u8aac\u306e\u4e2d\u3067\u306f\u3001\u53d6\u5f15\u5b89\u5168\u8aac\u306b\u6700\u3082\u8fd1\u3044\u3002<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>\u8d64\u4e95\u4f38\u90ce<\/strong>\uff08\u8457\u66f8\uff09<\/p>\n<p>\u8d64\u4e95\u4f38\u90ce\u3001\u6c93\u6fa4\u9686\u53f8\u3001\u7af9\u672c\u4ea8\u300e\u90fd\u5e02\u306b\u304a\u3051\u308b\u7a7a\u9593\u7d4c\u55b6\u306e\u8ca1\u653f\u5b66 &#8212; \u30b3\u30f3\u30d1\u30af\u30c8\u30b7\u30c6\u30a3\u304c\u3082\u305f\u3089\u3059\u6301\u7d9a\u53ef\u80fd\u306a\u81ea\u6cbb\u4f53\u904b\u55b6\u300f\uff082025\u5e7402\u6708\u520a\u884c\uff09<br \/>\n<a href=\"https:\/\/www.yuhikaku.co.jp\/books\/detail\/9784641166400\">https:\/\/www.yuhikaku.co.jp\/books\/detail\/9784641166400<\/a><\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">\u6982\u8981\uff1a\u90fd\u5e02\u306e\u30b3\u30f3\u30d1\u30af\u30c8\u5316\u304c\u8ca1\u653f\u3084\u4f4f\u6c11\u306e\u884c\u52d5\u30fb\u5065\u5eb7\u306b\u5bfe\u3057\u3066\u3082\u3064\u52b9\u679c\uff0c\u305d\u3057\u3066\u5730\u57df\u306e\u653f\u7b56\u304c\u30b3\u30f3\u30d1\u30af\u30c8\u5316\u306b\u53ca\u307c\u3059\u5f71\u97ff\u306b\u3064\u3044\u3066\uff0c\u5b9f\u8a3c\u7684\u306b\u89e3\u660e\u3059\u308b\u66f8\u7269\u3002\u65b0\u578b\u30b3\u30ed\u30ca\u30a6\u30a4\u30eb\u30b9\u611f\u67d3\u75c7\u3084\u4eba\u53e3\u6e1b\u5c11\u306e\u5f71\u97ff\u306a\u3069\u591a\u69d8\u306a\u8ad6\u70b9\u3082\u89e3\u8aac\u3059\u308b\uff0c\u30b3\u30f3\u30d1\u30af\u30c8\u30b7\u30c6\u30a3\u3092\u8003\u3048\u308b\u305f\u3081\u306e\u57fa\u672c\u66f8\u3002<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>Kento Nisugi <\/strong>\uff08\u66f8\u8a55\uff09<\/p>\n<p>&#8220;Book Review: Corporate Environmental Responsibility in Investor-State Dispute Settlement: The Unexhausted Potential of Current Mechanisms, by Tomoko Ishikawa.

The review commends Ishikawa\u2019s thorough legal and empirical research, including her quantitative study of 1,000 investment agreements, which challenges the assumption that counterclaims are largely unfeasible. While recognizing the book\u2019s valuable insights into jurisdictional hurdles and investor obligations, the review also discusses its limitations, particularly the structural constraints of the investment law regime. It concludes that Ishikawa\u2019s work is a significant contribution to legal scholarship, offering both theoretical depth and practical reform proposals.<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>\u4e2d\u5d8b\u5553\u96c4<\/strong>\uff08\u66f8\u8a55\uff09<\/p>\n<p>\u66f8\u8a55\uff1a\u300c\u68ee\u53e3\uff08\u571f\u5c4b\uff09\u7531\u9999\u30fb\u5ddd\u5cf6\u771f\u30fb\u5c0f\u6797\u8061\u660e\u7de8\u300e\u6587\u5316\u51b7\u6226\u3068\u77e5\u306e\u5c55\u958b\u2015\u2015\u30a2\u30e1\u30ea\u30ab\u306e\u6226\u7565\u30fb\u6771\u30a2\u30b8\u30a2\u306e\u8ad6\u7406\u2015\u2015\u300f\uff08\u4eac\u90fd\u5927\u5b66\u5b66\u8853\u51fa\u7248\u4f1a\u30012022\u5e74\uff09\u300d\u300e\u897f\u6d0b\u53f2\u5b66\u300f\u7b2c278\u53f7\uff082024\u5e7412\u6708\uff09\u300189\uff5e91\u9801<\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">\u6982\u8981\uff1a\u56fd\u969b\u5171\u540c\u7814\u7a76\u306e\u6210\u679c\u3067\u3042\u308b\u4e0a\u63b2\u66f8\u306e\u5b66\u8853\u7684\u610f\u7fa9\u3092\u8ad6\u3058\u3001\u82e5\u5e72\u306e\u8ab2\u984c\u3092\u6307\u6458\u3057\u3066\u3044\u308b\u3002<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>OSIPP\u57fa\u5e79\u8b1b\u5ea7\u6559\u54e1\u306e2\u6708\u306e\u7814\u7a76\u696d\u7e3e\u3092\u3054\u7d39\u4ecb\u3057\u307e\u3059\u3002 \u30fb\u5c0f\u539f\u7f8e\u7d00 \u5148\u751f\u3000\u3000\u30fb\u5c71\u4e0b\u62d3\u6717 \u5148\u751f \u30fb\u5927\u4e45\u4fdd\u90a6\u5f66 \u5148\u751f\u3000\u30fb\u8d64\u4e95\u4f38\u90ce \u5148\u751f \u30fb\u4e8c\u6749\u5065\u6597 \u5148\u751f\u3000\u3000\u30fb\u4e2d\u5d8b\u5553\u96c4 \u5148\u751f &nbsp; &nbsp; Miki Kohara &#8230;<\/p>\n","protected":false},"author":2,"featured_media":5548,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[8,12],"tags":[],"jetpack_featured_media_url":"https:\/\/news.osipp.osaka-u.ac.jp\/wp-content\/uploads\/2020\/06\/Achievement-1.jpg","_links":{"self":[{"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/15612"}],"collection":[{"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=15612"}],"version-history":[{"count":7,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/15612\/revisions"}],"predecessor-version":[{"id":15619,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/15612\/revisions\/15619"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/media\/5548"}],"wp:attachment":[{"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=15612"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=15612"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=15612"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
