Vasnev, \u201cThe role of data and priors in estimating climate sensitivity,\u201d Journal of the Royal Statistical Society Series C: Applied Statistics, qlaf047, 12 September 2025\uff08\u67fb\u8aad\u3042\u308a\uff09https:\/\/doi.org\/10.1093\/jrsssc\/qlaf047 Abstract: In Bayesian theory, the data together with the prior produce a posterior. We show that it is also possible to follow the opposite route, that is, to use data and posterior information (both of which are observable) to reveal the prior (which is not observable). We then apply the theory to equilibrium climate sensitivity as reported by the Intergovernmental Panel on Climate Change (IPCC) in an attempt to get some insights into the prior beliefs of the IPCC scientists.

Personalized pricing, which is private in nature, cannot influence expectations regarding the network sizes, inducing the platforms to offer lower participation fees for developers. Those lower fees increase network benefits for consumers, allowing the platforms to exploit these benefits through personalized pricing. Personalized prices are higher when the network value for developers is high, benefiting competing platforms at the expense of consumers. These findings offer policy insights on personalized pricing.

Published online: 12 September 2025. \uff08\u67fb\u8aad\u3042\u308a\uff09https:\/\/doi.org\/10.1111\/ajps.70010 Abstract: A fast-growing literature indicates that firms\u2019 engagement in foreign direct investment (FDI) and trade is key to understanding deepening global value chains and their political implications. However, existing studies have mainly focused on the ramifications for FDI home countries while often overlooking the firm-product level interactions between FDI and trade, where their interdependencies manifest. This study examines how firms\u2019 FDI reshapes host countries\u2019 trade profiles at this level, empowering new political coalitions for trade liberalization. Analyzing greenfield FDI projects globally since 2003, we find that hosts experienced an average increase of over 45 export products in the following year. To overcome the challenges of connecting firms to products, we link FDI data with Vietnamese customs records. We find that Vietnamese export (import) volumes of FDI-related products increased by 90% (30%) within 4 years of initial investments. Importantly, these products also benefited from more substantial tariff cuts in bilateral Free Trade Agreements.

In a stylized adverse selection model, we show that hard information enables trade, even when the unique equilibrium outcome without it is no-trade. Takuro Yamashita \uff08\u8ad6\u6587\uff09 Takeshi Murooka, Takuro Yamashita (2025) &#8220;Optimal Trade Mechanisms with Adverse Selection and Inferential Naivety,&#8221; American Economic Journal: Microeconomics, \uff08\u67fb\u8aad\u3042\u308a\uff09Forthcominghttps:\/\/www.aeaweb.org\/articles?id=10.1257\/mic.20230019&amp;&amp;from=f Abstract: We study an adverse selection environment in which a buyer\u2019s inferential ability is heterogeneous: A rational type correctly infers the value of the good from a seller\u2019s offer, whereas a naive type is inattentive to the correlation between the seller\u2019s private information and the offer. We characterize the optimal menu mechanism that maximizes the seller\u2019s profits or trade surplus. Notably, no matter how severe the adverse selection is, all types of buyers trade. We then provide conditions under which the menu mechanism is optimal among all general mechanisms. A consumer-protection policy that limits the naive buyer\u2019s loss is also investigated. \u9ad9\u7530\u967d\u5948\u5b50 \uff08\u8457\u66f8\uff09 \u300c\u56fd\u5185\u4eba\u6a29\u6a5f\u95a2\u300dpp.13-14\u3001\u5c0f\u5742\u7530\u88d5\u5b50\u4ed6\u7de8\u300e\u30a2\u30af\u30c6\u30a3\u30d6\u30e9\u30fc\u30cb\u30f3\u30b0\u56fd\u969b\u4eba\u6a29\u6cd5\u300f\uff08\u6cd5\u5f8b\u6587\u5316\u793e\u30012025\u5e74\uff09https:\/\/www.hou-bun.com\/cgi-bin\/search\/detail.cgi?c=ISBN978-4-589-04434-1 \u6982\u8981\uff1a\u672c\u66f8\u306f\u3001\u5b66\u90e8\u751f\u3084\u5927\u5b66\u9662\u751f\u3092\u4e3b\u306a\u5bfe\u8c61\u3068\u3057\u305f\u56fd\u969b\u4eba\u6a29\u6cd5\u306e\u6559\u79d1\u66f8\u3067\u3042\u308b\u3002\u3053\u306e\u6559\u79d1\u66f8\u306b\u304a\u3051\u308b\u300c\u56fd\u5185\u4eba\u6a29\u6a5f\u95a2\u300d\u306e\u9805\u76ee\u3092\u57f7\u7b46\u3057\u3001\u30d1\u30ea\u539f\u5247\u3084\u56fd\u5185\u4eba\u6a29\u6a5f\u95a2\u30b0\u30ed\u30fc\u30d0\u30eb\u9023\u76df\u306a\u3069\u306e\u56fd\u5185\u4eba\u6a29\u6a5f\u95a2\u306b\u304b\u304b\u308f\u308b\u57fa\u672c\u4e8b\u9805\u306b\u3064\u3044\u3066\u8aac\u660e\u3057\u3001\u56fd\u9023\u306e\u4eba\u6a29\u6761\u7d04\u6a5f\u95a2\u306e\u95a2\u9023\u3059\u308b\u5b9f\u8df5\u3084\u3001\u65e5\u672c\u306b\u304a\u3051\u308b\u56fd\u5185\u4eba\u6a29\u6a5f\u95a2\u306e\u8a2d\u7f6e\u306b\u95a2\u3059\u308b\u52d5\u5411\u306b\u3064\u3044\u3066\u89e3\u8aac\u3057\u305f\u3002 Takafumi Kawakubo \uff08Discussion Paper\uff09 Takafumi Kawakubo, Takafumi Suzuki &#8220;Spillovers through Supply Chains: How large plant openings affect local supplier firms&#8221;, RIETI Discussion Paper Series 25-E-083, September 2025https:\/\/www.rieti.go.jp\/jp\/publications\/nts\/25e083.html Abstract: This study examines how becoming a supplier to a newly established large-scale plant influences the performance of incumbent small plants. Exploiting detailed plant-level data, records of new large plant openings, and supply chain information, we construct a quasi-experimental setting based on the spatial distribution of new entrants. Our event-study estimates show that while local supplier plants benefit significantly\u2014both statistically and economically\u2014from large-scale plants, non-supplier plants in the same region face negative impacts, likely due to intensified competition spurred by the newly-contracted suppliers. The results underscore that such entries create \u201cwinners and losers\u201d not only across different regions but also within the same locality. From a policy perspective, these insights highlight the importance of facilitating effective partnerships between large-scale entrants and local suppliers, as well as offering support to disadvantaged non-supplier firms. Overall, our findings illuminate the nuanced local economic consequences of large-scale plant entries and offer guidance for future industrial and regional policies."}
