Chapter 1 summarizes the thesis. Chapter 2 shows that, contrary to common beliefs, the real options effect of uncertainty plays no role in the long run rate of investment. Real options and irreversibility, however, are shown to play an important role in the short run dynamics of investment and labor demand. Specifically, they reduce the short run response of investment and hiring to current demand shocks, and lead to a lagged response to past demand shocks. Chapter 3 derives robust empirical predictions on the effects of uncertainty on investment dynamics. This approach is based on an explicit aggregation across plants and lines of capital to the firm level, and is compatible with a general class of production functions and demand processes. An investment model is estimated on a panel of UK firms and finds that, as predicted, uncertainty significantly reduces firms&#8217; responsiveness to demand shocks. Chapters 4 extends these results by using a structural estimator of investment and labour demand at the plant level. Firms are modelled as operating a number of these separate production plants, which are subject to simulated plant level shocks and an observable firm level shock. Indirect inference is used to estimate the free parameters, and successfully match the time series and cross sectional behaviour of investment and hiring in a panel of US Compustat firms. Chapter 5 uses real options theory to model the investment in embodying newly patented products and processes. Patent data is collected for a panel of UK firms, and is shown to raises firms&#8217; market values and productivity. The effect on productivity, however, is reduced by higher levels of uncertainty, in line with predictions from the real options framework that uncertainty reduces the rate of embodiment of new-technologies.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>\u8ad6\u6587\u93c8\u63a5\uff1a<\/strong><\/p>\n<p><a href=\"https:\/\/www.proquest.com\/pqdtglobal\/docview\/1731947609\" target=\"_blank\" rel=\"noopener\">https:\/\/www.proquest.com\/pqdtglobal\/docview\/1731947609<\/a><\/p>\n<p>&nbsp;<\/p>\n<p><strong>ProQuest Dissertations &amp; Theses Global <\/strong><strong>\u7c21\u4ecb<\/strong><\/p>\n<p>ProQuest \u662f\u7f8e\u570b\u570b\u6703\u5716\u66f8\u9928\u6307\u5b9a\u7684\u6536\u85cf\u5168\u7f8e\u570b\u535a\u78a9\u58eb\u8ad6\u6587\u7684\u6a5f\u69cb\u3002 ProQuest \u5168\u7403\u535a\u78a9\u58eb\u8ad6\u6587\u5168\u6587\u8cc7\u6599\u5eab\uff08ProQuest Dissertations &amp; Theses Global\uff0c\u7c21\u7a31 PQDT Global\uff09\uff0c\u6536\u9304\u4f86\u81ea\u5168\u740360\u591a\u500b\u570b\u5bb6\/\u5730\u53404100\u9918\u6240\u5927\u5b78\u7684\u8d85\u904e400\u842c\u7bc7\u535a\u78a9\u58eb\u5b78\u4f4d\u8ad6\u6587\u5168\u6587\u53ca600\u842c\u7bc7\u6587\u6458\u7d22\u5f15\u8a18\u9304\u3002 \u5167\u5bb9\u8986\u84cb\u79d1\u5b78\u3001\u5de5\u7a0b\u5b78\u3001\u7d93\u6fdf\u8207\u7ba1\u7406\u79d1\u5b78\u3001\u5065\u5eb7\u8207\u91ab\u5b78\u3001\u6b77\u53f2\u5b78\u3001\u4eba\u6587\u53ca\u793e\u6703\u79d1\u5b78\u7b49\u9818\u57df\u3002<\/p>\n<p>\u5b58\u53d6\u7db2\u5740\uff1a<a href=\"https:\/\/www.proquest.com\/pqdtglobal\" target=\"_blank\" rel=\"noopener\">https:\/\/www.proquest.com\/pqdtglobal<\/a><\/p>\n<p>LibGuides: <a href=\"https:\/\/proquest.libguides.com\/pqdt\" target=\"_blank\" rel=\"noopener\">https:\/\/proquest.libguides.com\/pqdt<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>9\u670825\u65e5\uff0c\u79d1\u777f\u552f\u5b89\u516c\u4f48\u4e862025\u5e74\u5ea6\u5f15\u6587\u6842\u51a0\u734e\u540d\u55ae\uff0c\u7f8e\u570b\u65af\u4e39\u798f\u5927\u5b78\u7d93\u6fdf\u5b78\u7cfb William Eberl \u7d93\u6fdf\u5b78\u6559\u6388 Nicholas Bloom\uff0c\u56e0\u5728\u300c\u5206\u6790\u7d93\u6fdf\u8207\u653f\u6cbb\u4e0d\u78ba\u5b9a\u6027\u5c0d\u6295\u8cc7\u3001\u5c31\u696d\u8207\u589e\u9577\u7684\u5f71\u97ff\u300d\u7814\u7a76\u9818\u57df\u7684\u7a81\u51fa\u8ca2\u737b\uff0c\u7372\u5f972025\u5e74\u5ea6 \u7d93\u6fdf\u5b78 \u9818\u57df\u5f15\u6587\u6842\u51a0\u734e\u3002 &nbsp; Nicholas Bloom \u6559\u6388\/\u5716\u6e90\uff1aCitation Laureates \u5b98\u7db2 &nbsp; Nicholas Bloom\uff0c\u82f1\u570b\u502b\u6566\u5927\u5b78\u5b78\u9662\u535a\u58eb\uff0c\u5c0e\u5e2b\u70ba\u00a0John Van Reenen \u6559\u6388\u8207 Richard Blundell \u6559\u6388\u3002\u5176\u535a\u58eb\u8ad6\u6587\u984c\u76ee\u70ba\uff1aThe real options effects of uncertainty on investment&#8230;<\/p>\n","protected":false},"author":211,"featured_media":288884,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[928],"tags":[1213,1215],"class_list":["post-289317","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-academia-government","tag-citation-laureate-award","tag-pqdt-global","clarivate-industry-academia","clarivate-industry-government","clarivate-product-family-proquest","clarivate-product-proquest-dissertations-and-theses"],"acf":[],"lang":"zh","translations":{"zh":289317},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"pll_sync_post":[],"_links":{"self":[{"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/posts\/289317","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/users\/211"}],"replies":[{"embeddable":true,"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/comments?post=289317"}],"version-history":[{"count":7,"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/posts\/289317\/revisions"}],"predecessor-version":[{"id":289372,"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/posts\/289317\/revisions\/289372"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/media\/288884"}],"wp:attachment":[{"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/media?parent=289317"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/categories?post=289317"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/clarivate.com\/academia-government\/wp-json\/wp\/v2\/tags?post=289317"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
