Salvador Allende's development policy: Lessons after 50 years

Last year, 2020, was the 50th anniversary of the opening of the ‘Chilean road to socialism’ by Salvador Allende. Although the Allende government is the political reference for the 'socialism of the 21st century’ in Latin America, international supporters tend to disregard the primary cause of its downfall, focusing instead on the circumstances of Allende's death. This article explains the link between the Allende government's development policies and its macroeconomic outcomes between 1970 and 1973. It finds that Chile's economic collapse had an endogenous cause related to government policies. This supports the views of Mises and Hayek on the feasibility of socialist economic policies. Policymakers and commentators should recognise essential lessons from the Chilean experience to learn from past errors and effectively promote Latin America's economic development.     

关于企业成本管理的探讨

成本管理是预算管理和绩效管理的前提,企业需要正确地将成本进行分类、计量和归集。恰当的成本管理制度可以帮助企业提升运营效率和业务绩效,同时企业的流程改善、突破和优化与成本管理密不可分。另外,管理者需要令客户对产品和服务满意,并且有效控制各项成本。企业成本管理不是单纯地降低成本,而是通过利用成本分析工具,有效地管理和规划资源,进而提高总体运营效率,保证企业总体绩效的持续改善。论文通过成本计算制度的制定方法和业务流程改善分析技术两方面对成本管控进行探讨。     

疫情期间国际工程投标报价风险分析及费用计算方法研究

随着我国经济的快速发展和“走出去”、“一带一路”倡议的实施,越来越多的企业在政府的带动下开始进军国际市场,但是国际工程往往施工周期长、金额较大、技术复杂、政府干预较多、不确定性因素多,风险与机遇并存,针对2020年全球新冠病毒蔓延这一特殊的时期,企业更应在投标阶段做好风险分析、测算、管控工作,合理规避风险,总结经验教训,保证企业履约能力和竞争性。     

Economic planning must be polycentric,not monocentric: Introduction to a symposium on Mises and Hayek on socialism and knowledge

The roaring (20-) 20s are a decade of anniversaries and milestones. 2020 was the 100th anniversary of Ludwig von Mises's seminal article “Economic Calculation in the Socialist Commonwealth” and the 75th anniversary of F.A. Hayek's seminal article “The Use of Knowledge in Society.” 2022 brought a series of significant anniversaries: the 100th anniversary of Mises's Socialism: An Economic and Sociological Analysis as well as the 60th anniversary of James M. Buchanan and Gordon Tullock's The Calculus of Consent: Logical Foundations of Constitutional Democracy, Milton Friedman's Capitalism and Freedom, and Murray Rothbard's Man, Economy, and State. It was also the 20th anniversary of Vernon Smith's Nobel Prize. The works and milestones celebrating anniversaries in 2022 owe much to Mises's and Hayek's pathbreaking contributions. This paper summarizes and contextualizes Mises's and Hayek's arguments about socialism and knowledge and introduces a Southern Economic Journal symposium on the anniversaries of “Economic Calculation in the Socialist Commonwealth” and “The Use of Knowledge in Society.”

铁路三线大桥帽梁无支架法施工技术及受力检算

帽梁施工采用无支架法施工相对满堂支架法施工而言,具有施工简便,对地面承载力无要求,节约大量钢管,降低施工成本,缩短工期等优点。文章针对洛湛铁路旺甫1号三线大桥设计出穿心棒无支架法施工帽梁的支撑系统方案,成功地解决了三线大桥因帽梁砼重量大、跨度长而致使常用材料不适合做承托梁的问题,并对支撑系统进行了受力检算。     

Private Property or Several Control: A Rejoinder

Following Mises’s foundational paper, ‘Economic Calculation in the Socialist Commonwealth’, first published in 1920, writers in the Austrian tradition have argued that socialism is impossible, because under socialism there would be no private property in the means of production, and without that private property economic calculation could not take place. In the article ‘Economic Calculation: Private Property or Several Control?’, published in this journal in 2015, I argued that this was mistaken. Not private property, but several control, was required for economic calculation, and since several control is consistent with public ownership, this argument for the impossibility of socialism fails. Another article, ‘Private Property and Economic Calculation: A Reply to Andy Denis’, by Bylund and Manish, published in this issue of the Review of Political Economy, defends the traditional interpretation of Austrian reasoning, contending that my argument fails. My rejoinder re-states the issues, addressing, and, ultimately rejecting, the Bylund and Manish critique.
