We introduce lifetime uncertainty to the overlapping<br>generations model with heterogeneous households with varied<br>intertemporal preferences, where unintended bequests caused by death<br>are inherited by offspring. Aging can have both positive and negative<br>impacts on economic growth and fiscal sustainability: saving-enhancing<br>effects based on the life cycle theory and wealth-depletion effects<br>caused by extended longevity. When aging advances, saving-enhancing<br>effects are offset by wealth-depletion effects, which eventually<br>outweigh the former. The results show an \u201cinverted U-shaped\u201d<br>relationship between life expectancy and economic growth rate, or<br>fiscal sustainability. Numerical simulation reveals that aging can<br>produce a trade-off between economic growth and wealth inequality. We<br>also show that a rise in deficit or government expenditure ratio<br>exacerbates fiscal instability, economic growth, and wealth inequality<br>under certain conditions.<br>\u53f8\u4f1a\u8005\uff1a\u5c0f\u5ddd\u7fd4\u543e\uff08\u6a2a\u6d5c\u56fd\u7acb\u5927\u5b66\uff09<\/p>\n\n\n\n<p>\u25a114:00-14:40\u3000\u7b2c2\u5831\u544a<br>\u5831\u544a\u8005\uff1a\u52a0\u85e4\u60a0\u592a\uff08\u4eac\u90fd\u5927\u5b66\u5927\u5b66\u9662\u7d4c\u6e08\u5b66\u7814\u7a76\u79d1\u30fb\u4fee\u58eb\u8ab2\u7a0b\uff09<br>\u5831\u544a\u8ad6\u984c\uff1aEscaping the Middle Income Trap: The Role of Strategic Public<br>Investment and Industrial Structural Change<br>\u5831\u544a\u8981\u65e8\uff1aThis study examines how the middle-income trap occurs in<br>developing economies and how fiscal policies and development<br>strategies can help countries avoid or escape this development<br>challenge. Using a dual-sector model with public investment in<br>infrastructure and education, we analyze how different policy choices<br>affect growth trajectories and development outcomes. The findings<br>suggest that appropriate fiscal policies and investment strategies are<br>crucial for avoiding development traps and achieving sustainable<br>economic growth, but insufficient infrastructure investment and high<br>tax rate can lead to stagnation of industrialization and economic<br>development, potentially leading to a middle-income trap. The model<br>also reveals an important relationship between poverty traps and<br>middle-income traps, showing that even after escaping from initial<br>poverty through external assistance, countries need appropriate fiscal<br>policies to achieve sustainable development.<br>\u53f8\u4f1a\u8005\uff1a\u5ca1\u539f\u76f4\u4eba\uff08\u798f\u4e95\u770c\u7acb\u5927\u5b66\uff09<\/p>\n\n\n\n<p>\u25a114:50-16:10\u3000\u7b2c3\u5831\u544a<br>\u5831\u544a\u8005\uff1a\u4e8c\u5bae\u5065\u53f2\u90ce\uff08\u7acb\u6559\u5927\u5b66\uff09<br>\u5831\u544a\u8ad6\u984c\uff1aFinancial Structure and Monetary and Fiscal Policies<br>\u5831\u544a\u8981\u65e8\uff1aThe financial instability hypothesis of the heterodox economist<br>H.P.Minsky came to the fore as a result of the international financial<br>crisis triggered by the sub-prime mortgage crisis in the U.S. Many<br>post-Keynesian economists have developed Minsky&#8217;s arguments into<br>mathematical models that depict two types of Minskian financial<br>structures, which we identify as the lenders\u2019 risk type (LR) and the<br>hedge, speculative, and Ponzi type (HSP). We examine the effects of<br>monetary and fiscal policy in macrodynamic models that consider both<br>the LR and HSP financial structures. We demonstrate that the effects<br>depend on the significance of those structures. We emphasize the<br>significance of stable financial structures and the mix of monetary<br>and fiscal policies needed to stabilize the economy. However, we show<br>that the policy mix is not able to eliminate the fragility of the HSP<br>financial structure completely.<br>\u53f8\u4f1a\u8005\uff1a\u91d1\u5b50\u5275\uff08\u6771\u4eac\u90fd\u7acb\u5927\u5b66\uff09<\/p>\n\n\n\n<p>\u25a116:20-17:40\u3000\u7b2c4\u5831\u544a<br>\u5831\u544a\u8005\uff1a\u5e73\u91ce\u5609\u5b5d\uff08\u5bcc\u5c71\u770c\u7acb\u5927\u5b66\uff09<br>\u5831\u544a\u8ad6\u984c\uff1a\u30b9\u30e9\u30c3\u30d5\u30a1\u306e\u5b58\u7d9a\u53ef\u80fd\u6027\u3068\u5270\u4f59\u6982\u5ff5<br>\u5831\u544a\u8981\u65e8\uff1a\u7523\u51fa\u91cf\u3067\u6295\u5165\u91cf\u3092\u5272\u308a\u6280\u8853\u4fc2\u6570\u306b\u5909\u63db\u3059\u308b\u3053\u3068\u3092\u305b\u305a\u306b\u3001<br>\u7d4c\u6e08\u5206\u6790\u3092\u884c\u3046\u3053\u3068\u3092\u300c\u5546\u54c1\u306e\u751f\u7523\u56f3\u5f0f\u300d\u3092\u7528\u3044\u308b\u3068\u547c\u3076\u3053\u3068\u306b\u3059\u308b\u3002<br>\u300c\u5546\u54c1\u306e\u751f\u7523\u56f3\u5f0f\u300d\u3092\u5229\u7528\u3057\u3001\u4e3b\u306b\u6570\u5024\u4f8b\u3092\u7528\u3044\u3066\u3001<br>\u300c\u81ea\u5df1\u3067\u306a\u3044\u3082\u306e\u3092\u88dc\u586b\u3059\u308b\u300d\u72b6\u614b\u306e\u5206\u6790\u88c5\u7f6e\u3068\u3057\u3066\u306e\u610f\u7fa9\u3092\u554f\u3044\u76f4\u3059\u3002<br>\u307e\u305f\u3001\u6700\u5c0f\u5358\u4f4d\u306e\u4e3b\u4f53\u306f\u4ee3\u8868\u7684\u4f01\u696d\u3067\u306f\u306a\u304f\u3001\u5546\u54c1\u3067\u3042\u308b\u3053\u3068\u306e\u5206\u6790\u7684\u542b\u610f\u306b\u3082\u3075\u308c\u308b\u3002<br>\u4ee5\u4e0a\u306e\u5206\u6790\u3092\u8e0f\u307e\u3048\u3001\u30b9\u30e9\u30c3\u30d5\u30a1\u6587\u66f8\u3082\u5229\u7528\u3057\u3001\u30b9\u30e9\u30c3\u30d5\u30a1\u306e\u5270\u4f59\u6982\u5ff5\u3092\u518d\u8003\u3059\u308b\u3002<br>\u53f8\u4f1a\u8005\uff1a\u9ed2\u702c\u4e00\u5f18\uff08\u6771\u5317\u5927\u5b66\uff09<\/p>\n\n\n\n<p>\u25a117:45-17:55\u3000\u7dcf\u62ec<br>\u6d45\u7530\u7d71\u4e00\u90ce\uff08\u4e2d\u592e\u5927\u5b66\uff09<\/p>\n\n\n\n<p>\u25a117:55-18:00\u3000\u9589\u4f1a\u6328\u62f6<br>\u4f50\u3005\u6728\u5553\u660e\uff08\u4eac\u90fd\u5927\u5b66\uff09<\/p>\n\n\n\n<p>\u25a118:30-\u3000\u61c7\u89aa\u4f1a<\/p>\n\n\n\n<p>\uff08\u5171\u50ac\uff1a\u4eac\u90fd\u5927\u5b66\u5927\u5b66\u9662\u7d4c\u6e08\u5b66\u7814\u7a76\u79d1\u30fb\u7d4c\u6e08\u52d5\u5b66\u30bb\u30df\u30ca\u30fc<br><a href=\"http:\/\/www.econ.kyoto-u.ac.jp\/~sasaki\/economic_dynamics_seminar.html\" rel=\"noreferrer noopener\" target=\"_blank\">http:\/\/www.econ.kyoto-u.ac.jp\/~sasaki\/economic_dynamics_seminar.html<\/a>&nbsp;\uff09<\/p>\n\n\n\n<p>\u4f1a\u5834\u6e96\u5099\u306e\u90fd\u5408\u4e0a\u30016\u67089\u65e5\uff08\u6708\uff09\u307e\u3067\u306b\u3001\u7814\u7a76\u4f1a\u304a\u3088\u3073\u61c7\u89aa\u4f1a\u306e\u3054\u51fa\u6b20\u3092\u4f50\u3005\u6728\u5b9b\uff08sasaki.hiroaki.7x[@]<a href=\"http:\/\/kyoto-u.ac.jp\/\" rel=\"noreferrer noopener\" target=\"_blank\">kyoto-u.ac.jp<\/a>\uff09\u306b\u304a\u77e5\u3089\u305b\u3044\u305f\u3060\u3051\u307e\u3057\u305f\u3089\u5e78\u3044\u3067\u3059\u3002<br>________________________________<br>PK \u7814\u5e79\u4e8b: \u6e21\u8fba\u548c\u5247\u3001\u6d45\u7530\u7d71\u4e00\u90ce\u3001\u4f50\u3005\u6728\u5553\u660e\u3001\u5927\u91ce\u9686\u3001\u9ed2\u702c\u4e00\u5f18\u3001\u6c60\u7530\u6bc5\u3001\u5185\u85e4\u6566\u4e4b<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u30dd\u30b9\u30c8\u30fb\u30b1\u30a4\u30f3\u30ba\u6d3e\u7d4c\u6e08\u5b66\u7814\u7a76\u4f1a\u306e\u304a\u77e5\u3089\u305b\u3067\u3059\u3002\u4eca\u56de\u306f\u4eac\u90fd\u3067\u306e\u958b\u50ac\u3067\u3001\u4eac\u90fd\u5927\u5b66\u5927\u5b66\u9662\u7d4c\u6e08\u5b66\u7814\u7a76\u79d1\u30fb\u7d4c\u6e08\u52d5\u5b66\u30bb\u30df\u30ca\u30fc\u3068\u306e\u5171\u50ac\u3068\u306a\u308a\u307e\u3059\u3002 &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#038;
