Public credit and liquidity in James Steuart's Principles

Abstract

The aim of this article is to shed new light on the monetary and financial theory of James Steuart (1767) through his examination of the speculative bubbles of 1720: that is, the John Law System in France and the South Sea Bubble in England. In contrast to most contemporary writers – particularly David Hume and Adam Smith – Steuart had a balanced opinion about these two financial experiments. On the one hand, Steuart considered them worthwhile, since they were attempts at public debt restructuring by reducing its expense and increasing its liquidity. Moreover, according to Steuart, a well-managed public debt favours the liquidity of both banks and the financial market. These worked together for the growth of wealth. However, on the other hand, Steuart claimed that the failure of these experiments was due to: (i) a poor management of money; (ii) a violation of credit rules and its corollary, the weakness of banks; (iii) the adoption of contestable dividend and financial information policy. This article presents Steuart's proposals for creating the liquidity of both banks and the financial market via a well-managed public debt.     

聚隆煤矿2202工作面陷落柱导水性分析

聚隆煤矿2202工作面在掘进过程中揭露一岩溶陷落柱,结合对此陷落柱的探测成果和该矿的探放水试验资料,从陷落柱柱体和其周边裂隙带两方面进行导水性分析。由于陷落柱柱体具有明显的阻水性以及其所处的地下水流场径流条件较差所以柱体导水的可能性很小;而陷落柱周边裂隙带由于处在较高地下水压环境中,受采动影响可能活化导水,所以该工作面不宜直接推采,须采取必要的防治水措施过陷落柱。

强制责任保险能降低食品行业的股价崩盘风险吗?

利用中国食品安全强制责任保险制度的外生冲击,实证探究强制责任保险制度的实施对股价崩盘风险的影响。研究发现：基于保险机构的监管效应,强制责任保险制度的实施通过加强食品生产监管降低经营业绩波动,显著降低食品上市公司的股价崩盘风险;而且该政策效应在非国有上市公司、机构投资者持股较少以及信息不对称较高的上市公司更加显著。由此表明,公共与私营部门所形成的共同监管机制能有效加强食品安全监管。
