Treaty organs review the decision-making process of each type of state organ \u2013 courts, parliaments and administrative organs \u2013 and make remedial orders that are substantially addressed to specific state organs. Such phenomena go hand in hand with the relativization of the distinction between the legal spheres in which human rights treaty organs and state organs operate. This is the first study to address such phenomena as a totality. It constructs the \u2018separation of powers in a globalized democratic society\u2019 theory, thereby proposing how each type of state organ and the treaty organs should interact under human rights treaties. Its findings contribute, first, to the harmonious achievement of the effectiveness and democratic legitimacy of human rights treaties; second, to the reform of the classical paradigm of international law, in which monolithic states are the only relevant legal entities; and third, to the long-standing debates on the relationship between international and national laws from a new angle.<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>Azusa Katagiri<\/strong>\uff08\u8ad6\u6587\uff09<\/p>\n<p>\u201dRevisiting the puzzle of endogenous nuclear proliferation\u201d <em>Journal of Peace Research<\/em>\uff08\u67fb\u8aad\u6709\uff09 <a href=\"https:\/\/journals.sagepub.com\/doi\/10.1177\/00223433231177727\">https:\/\/journals.sagepub.com\/doi\/10.1177\/00223433231177727<\/a><\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">Abstract\uff1aNuclear proliferation literature typically differentiates supply-side and demand-side factors influencing the spread of nuclear weapons. These distinct approaches to the proliferation puzzle raise the following empirical questions: Does nuclear supply stimulate states\u2019 demand for nuclear weapons? Conversely, does the demand for nuclear weapons really facilitate the acquisition of nuclear supply? If such endogeneity exists between the demand-side and supply-side determinants, how would it cause empirical bias in the estimation of their effects on nuclear proliferation? This article aims to unpack endogenous mechanisms of nuclear demand and nuclear supply over the course of nuclear proliferation. In particular, it examines two potential sources of endogeneity: (1) simultaneous interactions between states\u2019 nuclear development decisions and nuclear technological capability and (2) selection bias in nuclear development. To address each source of endogeneity, simultaneous equation models and the duration models with selection are estimated, respectively. Contrary to what recent supply-side literature suggests, the empirical analyses reveal that states\u2019 nuclear demand is primarily driven by external security threats instead of their existing nuclear technology, and that their successful acquisition of nuclear technology mainly follows as the result of nuclear development efforts but does not necessarily depend on individual supply-side factors. This article addresses the typical inference issues in nuclear proliferation research and contributes to our synthetic understanding of proliferation mechanisms.<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>\u4e8c\ufa1e\u79c0\u548c<\/strong>\uff08\u305d\u306e\u4ed6\u306e\u8a18\u4e8b\uff09<\/p>\n<p>\u300c\u9577\u671f\u56fd\u50b5\u8cb7\u3044\u5165\u308c\u306b\u306f\u3069\u306e\u3088\u3046\u306a\u52b9\u679c\u304c\u3042\u308b\u306e\u304b\u300d\u300e<a href=\"https:\/\/str.toyokeizai.net\/magazine\/toyo\/20230821\/\">\u9031\u520a\u6771\u6d0b\u7d4c\u6e08<\/a>\u300f\u6771\u6d0b\u7d4c\u6e08\u65b0\u5831\u793e2023\u5e748\/26\u7b2c7131\u53f7<\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">\u6982\u8981\uff1a\u65e5\u672c\u9280\u884c\u306f\u30012013\u5e744\u6708\u304b\u3089\u30012%\u30a4\u30f3\u30d5\u30ec\u76ee\u6a19\u3092\u9054\u6210\u3059\u308b\u305f\u3081\u306b\u91cf\u7684\u30fb\u8cea\u7684\u91d1\u878d\u7de9\u548c\u653f\u7b56\u3092\u5b9f\u65bd\u3057\u3066\u3044\u308b\u3002\u3053\u306e\u9593\u3001\u65e5\u672c\u9280\u884c\u306f\u3001\u65e5\u9280\u5f53\u5ea7\u9810\u91d1\u3068\u5f15\u304d\u63db\u3048\u306b\u5927\u91cf\u306e\u9577\u671f\u56fd\u50b5\u3092\u8cfc\u5165\u3057\u3066\u304d\u305f\u3002\u672c\u7a3f\u3067\u306f\u3001\u4e2d\u592e\u9280\u884c\u306e\u9577\u671f\u56fd\u50b5\u8cb7\u5165\u308c\u306e\u52b9\u679c\u306b\u3064\u3044\u3066\u3001\u30de\u30af\u30ed\u7d4c\u6e08\u7406\u8ad6\u306e\u89b3\u70b9\u304b\u3089\u691c\u8a0e\u3059\u308b\u3002\u3068\u304f\u306b\u3001\u7269\u4fa1\u6c34\u6e96\u306e\u8ca1\u653f\u7406\u8ad6\u306b\u57fa\u3065\u3044\u3066\u8b70\u8ad6\u3059\u308b\u3002\u540c\u7406\u8ad6\u306f\u3001\u8ca8\u5e63\u7d4c\u6e08\u7406\u8ad6\u306e\uff11\u3064\u3067\u3042\u308a\u3001\u653f\u5e9c\u50b5\u52d9\u306e\u6301\u7d9a\u53ef\u80fd\u6027\u306e\u554f\u984c\u304c\u30a4\u30f3\u30d5\u30ec\u7387\u306e\u6c7a\u5b9a\u306b\u53ca\u307c\u3059\u5f71\u97ff\u306b\u3064\u3044\u3066\u8003\u5bdf\u3059\u308b\u3082\u306e\u3067\u3042\u308b\u3002<\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<p><strong>Takeshi Murooka\u3000<\/strong>coauthored with Yuichi Yamamoto\uff08Discussion Paper\uff09<\/p>\n<p>\u201cHigher-Order Misspecification and Equilibrium Stability\u201d DP-2023-E-002 (August 2, 2023)\u00a0 <a href=\"https:\/\/www.osipp.osaka-u.ac.jp\/archives\/DP\/2023\/DP2023E002.pdf\">https:\/\/www.osipp.osaka-u.ac.jp\/archives\/DP\/2023\/DP2023E002.pdf<\/a><\/p>\n<\/blockquote>\n<p style=\"padding-left: 10px;\">Abstract\uff1aThis paper considers a Bayesian learning problem where strategic players jointly learn an unknown economic state, and show that one&#8217;s higher-order misspecification (i.e., one&#8217;s misspecification about the opponent&#8217;s misspecification) can have a significant impact on the equilibrium outcome. We consider a simple environmental problem where players&#8217; production, as well as an unknown state, affects the quality of the environment. Crucially, we assume that one of the players is unrealistically optimistic about the quality of the environment. When this optimism is common knowledge, the equilibrium outcome is continuous in the amount of optimism, and hence small optimism leads to approximately correct learning of the state. In contrast, when the optimism is not common knowledge and each player is unaware of the opponent having a different view about the world, the equilibrium outcome is discontinuous, and even vanishingly small optimism leads to completely incorrect learning. We then analyze a general Bayesian learning model and discuss when such discontinuity arises.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>OSIPP\u57fa\u5e79\u8b1b\u5ea7\u6559\u54e1\u306e8\u6708\u306e\u7814\u7a76\u696d\u7e3e\u3092\u3054\u7d39\u4ecb\u3057\u307e\u3059\u3002 \u30fb\u677e\u6797\u54f2\u4e5f \u5148\u751f\u3000\u30fb\u9ad9\u7530\u967d\u5948\u5b50 \u5148\u751f \u30fb\u7247\u6850\u6893 \u5148\u751f\u00a0 \u3000 \u30fb\u4e8c\ufa1e\u79c0\u548c \u5148\u751f \u30fb\u5ba4\u5ca1\u5065\u5fd7 \u5148\u751f &nbsp; &nbsp; \u677e\u6797\u54f2\u4e5f\uff08\u8457\u66f8\uff09 \u300e\u4f55\u304c\u6295\u7968\u7387\u3092\u9ad8\u3081\u308b\u306e &#8230;<\/p>\n","protected":false},"author":2,"featured_media":5548,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[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\/13080"}],"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=13080"}],"version-history":[{"count":11,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/13080\/revisions"}],"predecessor-version":[{"id":13093,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/13080\/revisions\/13093"}],"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=13080"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=13080"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news.osipp.osaka-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=13080"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
