财政政策视角下非正规经济对就业影响的静态模型分析

非正规经济在我国呈急剧膨胀之势,而其对就业产生了重要的影响.本文从财政政策的角度,对非正规经济是如何通过政府的财政收支对就业产生影响进行了经济学分析,并得出结论:非正规经济会导致对失业率的高估.因此本文提出建议:非正规经济应在政策上予以引导和管理,使其在就业中发挥其应有的积极作用.     

技术进步效率测度模型的构建及应用

技术进步是影响经济增长的决定性因素,因此,技术进步的测度成为一个重要的研究问题。然而,技术进步的测度到目前为止还没有统一和令人信服的方法。本文使用DEA方法,基于理想生产前沿面构建了技术进步效率测度模型。技术进步效率测度模型是技术进步度量的一种新方法,是一个相对量的测量,规避了技术进步总量测算模型的一些缺陷。将模型用于测算我国1999～2008年的技术进步效率,测算结果表明我国大多数地区技术进步效率呈逐年上升的趋势,经济产出较高而同时消耗了较低资源投入的省份具有较高的技术进步效率。这说明低消耗的技术进步才是有效的,能够有效支撑经济的可持续发展。

Equilibria with nonstandard prices in vector lattice overlapping generations economies

The paper investigates overlapping generations (OLG) economies in vector lattices framework. Agents' preferences are assumed uniformly proper, though they may be nontransitive and incomplete. Existence is stated for the “equilibrium with nonstandard prices,” a notion that may be looked upon as a particular (or generalized, in other aspect) case of known “compensated equilibria” of OLG-economies. The difference is that compensated values are described via explicit formula given in nonstandard analysis terms. This approach enables more clear economic interpretation and shows some new properties of compensated values, such as their linearity over agents' endowments. Also it allows easy to prove the existence of equilibria under classical additional assumptions on agents' endowments.     

A Magnetically Separable Catalyst for Synthesis of 1‐Phenoxy‐2‐propanol Via Atom‐economic Reaction

A magnetically separable catalyst Al₂O₃‐MgO/Fe₃O₄ was prepared by Al₂O₃‐MgO supported on magnetic oxide Fe₃O₄ and charactered by FT‐IR, XRD and SEM. The mixed oxides afforded high catalytic activity and selectivity for synthesis of 1‐phenoxy‐2‐propanol from phenol and propylene oxide with 80.3% conversion and 88.1% selectivity to 1‐phenoxy‐2‐propanol. Especially, facile separation of the catalyst by a magnet was obtained and the catalytic performance of the recovered catalyst was unaffected even at the forth run.     

Using N‐Tosylhydrazone as a Double Nucleophile in the Palladium‐Catalyzed Cross‐Coupling Reaction To Synthesize Allylic Sulfones

Without extra addition of sulfinate salt, allylic sulfones were synthesized by palladium‐catalyzed cross‐coupling of aryl iodide with N‐tosylhydrazone. In this transformation, not only the diazo compound but also the sulfinate salt, which were both generated in situ from base‐mediated decomposition of the N‐tosylhydrazone, was used as nucleophilic partner.
