Max Shen<i class=\"flaticon flaticon-next author-arrow\"><\/i><\/a><\/div><div class=\"article-content\">With the rapid growth of omnichannel retailing and the takeaway delivery economy, the classic point-to-point mode for on-demand delivery is deficient in delivery capacity, coverage area, dispatching efficiency, and courier safety assurance. Inspired by the success of Dabbawala, a historical Indian company for lunch delivery, we propose a novel\u00a0public on-demand delivery service system\u00a0that uses the public transit network to satisfy stochastic delivery demands. In particular, the proposed system includes a radial public transit network for intermediate transshipment, as well as couriers with e-bikes for terminal pick-up and drop-off. Our research aims to generate system design that minimizes the sum of penalty costs from lost sales and operational costs associated with courier terminal delivery distance. Solving the integrated system optimization problem relies on incorporating operational details, especially the allocation strategies of the lines\u2019 capacity and the couriers\u2019 terminal traveling modes. For the former, we propose a novel flexible design, called dual long-chain design, to improve flexibility. For the latter, we propose an elegant approximation of optimal service region partitioning that minimizes the expected terminal delivery distance and the resulting costs, without compromising delivery timeliness. Leveraging the theoretical results of the operational strategies, we simplify the integrated optimization problem and propose an efficient approximation algorithm. Finally, we validate the advantage of the proposed system over classic point-to-point delivery in satisfying demands and reducing costs through extensive numerical experiments, providing managerial insights in handling massive on-demand delivery demands and utilizing the idle capacity of the public transit system.<\/div><div class=\"blog-post_datetime\">May 2026<\/div><div class=\"blog-post_category\">Production and Operations Management<\/div><hr class='article-divider'><div class='article-links'><div class=\"links\"><i class=\"flaticon flaticon-next link-arrow\"><\/i><a href=\"https:\/\/doi.org\/10.1177\/10591478251394130\">External Link<\/a><\/div><\/div><\/div><\/div><\/div><\/div><div class='wgl_col-4 item fadeInUp animated' data-animate='fadeInUp' data-order=5><div class='blog-post format-gallery'><div class=\"blog-post_wrapper\"><div class=\"blog-post_media\"><div class=\"blog-post_media_part\"><span><a href=\"https:\/\/doi.org\/10.1016\/j.jpubeco.2026.105615\" class=\"blog-post_feature-link \"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"440\" src=\"https:\/\/www.hkubs.hku.hk\/wp-content\/uploads\/fly-images\/256865\/pub_202605_ECON_CaiH_ChenH_ZhangS_Cronies-680x440-c.jpg\" class=\"attachment-event-thumbnail\" alt=\"Cronies in the Courtroom: Political Interference and Judicial Reforms\" \/><\/a><\/span><\/div><\/div><div class=\"blog-post_content\"><div class=\"blog-post_title\"><a href=\"https:\/\/doi.org\/10.1016\/j.jpubeco.2026.105615\" class=\"blog-post_feature-link\">Cronies in the Courtroom: Political Interference and Judicial Reforms<\/a><\/div><div class=\"thought-leadership-item_researcher\"><a href=\"https:\/\/www.hkubs.hku.hk\/people\/heng-chen\/\">Prof. Heng CHEN<i class=\"flaticon flaticon-next author-arrow\"><\/i><\/a><a href=\"https:\/\/www.hkubs.hku.hk\/people\/sisi-zhang-3\/\">Dr. Sisi ZHANG<i class=\"flaticon flaticon-next author-arrow\"><\/i><\/a><\/div><div class=\"article-content\">Utilizing 1.54 million judicial judgments from enterprise-to-enterprise litigation between 2014 and 2019 in China, we provide evidence of municipal leaders exerting influence over the courts to favor enterprises connected to them. By leveraging variations in enterprise connections resulting from official turnover, we show that enterprises with connections to party leaders have higher chances of winning in business litigation than unconnected enterprises. We also examine the impact of the staggered roll-out of circuit courts, a top-down institutional reform, on cronyism in the courtroom. Our findings show that this reform has effectively reduced the judicial advantage enjoyed by connected enterprises by two-thirds. By contrast, the trial live-broadcasting reform increases visibility but is not associated with a reduction in the effect of political connections, suggesting that different forms of judicial bias require different monitoring approaches.<\/div><div class=\"blog-post_datetime\">May 2026<\/div><div class=\"blog-post_category\">Journal of Public Economics<\/div><hr class='article-divider'><div class='article-links'><div class=\"links\"><i class=\"flaticon flaticon-next link-arrow\"><\/i><a href=\"https:\/\/doi.org\/10.1016\/j.jpubeco.2026.105615\">External Link<\/a><\/div><\/div><\/div><\/div><\/div><\/div><div class='wgl_col-4 item fadeInUp animated' data-animate='fadeInUp' data-order=6><div class='blog-post format-gallery'><div class=\"blog-post_wrapper\"><div class=\"blog-post_media\"><div class=\"blog-post_media_part\"><span><a href=\"https:\/\/doi.org\/10.1016\/j.jinteco.2026.104238\" class=\"blog-post_feature-link \"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"440\" src=\"https:\/\/www.hkubs.hku.hk\/wp-content\/uploads\/fly-images\/256489\/pub_202605_FINA_LiuX_Preferential-680x440-c.jpg\" class=\"attachment-event-thumbnail\" alt=\"Preferential Credit Policy with Sectoral Markup Heterogeneity\" \/><\/a><\/span><\/div><\/div><div class=\"blog-post_content\"><div class=\"blog-post_title\"><a href=\"https:\/\/doi.org\/10.1016\/j.jinteco.2026.104238\" class=\"blog-post_feature-link\">Preferential Credit Policy with Sectoral Markup Heterogeneity<\/a><\/div><div class=\"thought-leadership-item_researcher\"><a href=\"https:\/\/www.hkubs.hku.hk\/people\/xuewen-liu\/\">Prof. Xuewen LIU<i class=\"flaticon flaticon-next author-arrow\"><\/i><\/a><\/div><div class=\"article-content\">Many emerging economies employ preferential credit policies that target selected sectors. This paper quantifies the implications of such policies for aggregate productivity and welfare. Using Chinese firm-level data from 2009\u20132020, we first document that sectors with higher markups receive larger credit subsidies and exhibit higher revenue-based productivity. Motivated by these facts, we develop a multi-sector quantitative model with endogenously determined markups and calibrate it to match the distribution of sales both within and across sectors. We find that preferential credit subsidies raise aggregate productivity and welfare by reallocating market shares toward high-markup sectors. These gains persist in an extended framework with endogenous firm entry.<\/div><div class=\"blog-post_datetime\">May 2026<\/div><div class=\"blog-post_category\">Journal of International Economics<\/div><hr class='article-divider'><div class='article-links'><div class=\"links\"><i class=\"flaticon flaticon-next link-arrow\"><\/i><a href=\"https:\/\/doi.org\/10.1016\/j.jinteco.2026.104238\">External Link<\/a><\/div><\/div><\/div><\/div><\/div><\/div><div class='wgl_col-4 item fadeInUp animated' data-animate='fadeInUp' data-order=7><div class='blog-post format-gallery'><div class=\"blog-post_wrapper\"><div class=\"blog-post_media\"><div class=\"blog-post_media_part\"><span><a href=\"https:\/\/doi.org\/10.1111\/1475-679X.70016\" class=\"blog-post_feature-link \"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"440\" src=\"https:\/\/www.hkubs.hku.hk\/wp-content\/uploads\/fly-images\/256855\/pub_202605_FINA_TangD_The-680x440-c.jpg\" class=\"attachment-event-thumbnail\" alt=\"The Determinants of ESG Ratings: Rater Ownership Matters\" \/><\/a><\/span><\/div><\/div><div class=\"blog-post_content\"><div class=\"blog-post_title\"><a href=\"https:\/\/doi.org\/10.1111\/1475-679X.70016\" class=\"blog-post_feature-link\">The Determinants of ESG Ratings: Rater Ownership Matters<\/a><\/div><div class=\"thought-leadership-item_researcher\"><a href=\"https:\/\/www.hkubs.hku.hk\/people\/dragon-yongjun-tang\/\">Prof. Dragon Yongjun TANG<i class=\"flaticon flaticon-next author-arrow\"><\/i><\/a><\/div><div class=\"article-content\">We examine whether and how common ownership affects Environmental, Social, and Governance (ESG) ratings\u2014an important research question given the increasing use of these ratings in investment decisions and corporate evaluations. We find that companies with major shareholders in common with the rating agency (\u201csister firms\u201d) tend to receive higher ESG ratings. When a company becomes a sister firm through a change in the rating agency's ownership structure, its rating from that agency is subsequently upgraded, whereas its ESG ratings from other agencies remain unchanged. Sister firms exhibit greater rating disagreements across agencies than other firms. The higher ESG ratings for sister firms are partly attributable to the transfer of immaterial positive ESG information through common owners. The common ownership effect is more pronounced when the owner can exert a greater influence on the rating agency. Moreover, sister firms with initially elevated ratings demonstrate poorer future ESG performance. Overall, our findings suggest that owners can affect ESG ratings of their portfolio companies in a way consistent with their influence and interest.<\/div><div class=\"blog-post_datetime\">May 2026<\/div><div class=\"blog-post_category\">Journal of Accounting Research<\/div><hr class='article-divider'><div class='article-links'><div class=\"links\"><i class=\"flaticon flaticon-next link-arrow\"><\/i><a href=\"https:\/\/doi.org\/10.1111\/1475-679X.70016\">External Link<\/a><\/div><\/div><\/div><\/div><\/div><\/div><div class='wgl_col-4 item fadeInUp animated' data-animate='fadeInUp' data-order=8><div class='blog-post format-gallery'><div class=\"blog-post_wrapper\"><div class=\"blog-post_media\"><div class=\"blog-post_media_part\"><span><a href=\"https:\/\/www.scmp.com\/opinion\/hong-kong-opinion\/article\/3351772\/how-hong-kongs-institutional-strengths-can-power-its-five-year-plan\" class=\"blog-post_feature-link \"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"440\" src=\"https:\/\/www.hkubs.hku.hk\/wp-content\/uploads\/fly-images\/259728\/adfs-f-680x440-c.jpg\" class=\"attachment-event-thumbnail\" alt=\"\u767c\u63ee\u9999\u6e2f\u5236\u5ea6\u512a\u52e2 \u52a9\u529b\u300c\u4e94\u5e74\u898f\u5283\u300d\u767c\u5c55\" \/><\/a><\/span><\/div><\/div><div class=\"blog-post_content\"><div class=\"blog-post_title\"><a href=\"https:\/\/www.scmp.com\/opinion\/hong-kong-opinion\/article\/3351772\/how-hong-kongs-institutional-strengths-can-power-its-five-year-plan\" class=\"blog-post_feature-link\">\u767c\u63ee\u9999\u6e2f\u5236\u5ea6\u512a\u52e2 \u52a9\u529b\u300c\u4e94\u5e74\u898f\u5283\u300d\u767c\u5c55<\/a><\/div><div class=\"thought-leadership-item_researcher\"><a href=\"https:\/\/www.hkubs.hku.hk\/people\/heiwai-tang\/\">Prof. Heiwai TANG<i class=\"flaticon flaticon-next author-arrow\"><\/i><\/a><\/div><div class=\"article-content\"><\/div><div class=\"blog-post_datetime\">30 Apr 2026<\/div><div class=\"blog-post_category\">\u6559\u5b78\u4eba\u54e1<\/div><hr class='article-divider'><div class='article-links'><div class=\"links\"><i class=\"flaticon flaticon-next link-arrow\"><\/i><a href=\"https:\/\/www.scmp.com\/opinion\/hong-kong-opinion\/article\/3351772\/how-hong-kongs-institutional-strengths-can-power-its-five-year-plan\">\u5357\u83ef\u65e9\u5831\uff08\u82f1\u6587\uff09<\/a><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"pagination acenter\"><span aria-current=\"page\" class=\"page-numbers current\">1<\/span><a class=\"page-numbers\" href=\"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages\/54483\/?pg=2&\">2<\/a><a class=\"page-numbers\" href=\"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages\/54483\/?pg=3&\">3<\/a><span class=\"page-numbers dots\">&hellip;<\/span><a class=\"page-numbers\" href=\"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages\/54483\/?pg=162&\">162<\/a><a class=\"next page-numbers\" href=\"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages\/54483\/?pg=2&\"><i class=\"arrow right\"><\/i><span class=\"sr-only\">\u4e0b\u4e00\u9801<\/span><\/a><input type=\"text\" aria-label=\"\u8f38\u5165\u9801\u6578\" class=\"page-textbox\"><div class=\"max-page-number\">\/162<\/div><\/div><\/section><\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":54463,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"thought-leadership-listing.php","meta":{"_lmt_disableupdate":"no","_lmt_disable":"","footnotes":""},"class_list":["post-54483","page","type-page","status-publish","hentry"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages\/54483","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/comments?post=54483"}],"version-history":[{"count":1,"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages\/54483\/revisions"}],"predecessor-version":[{"id":54484,"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages\/54483\/revisions\/54484"}],"up":[{"embeddable":true,"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/pages\/54463"}],"wp:attachment":[{"href":"https:\/\/www.hkubs.hku.hk\/tc\/wp-json\/wp\/v2\/media?parent=54483"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
