阻碍燃煤电厂烟气脱硫的症结及出路

燃煤电厂基本是高架源排放二氧化硫污染物，对本地区的污染贡献率不大，地方政府对其治理缺乏积极性；由于其脱硫成本远高于我国二氧化硫排污费征收标准，导致排污企业宁愿交纳排污费而不愿治理污染。因此控制燃煤电厂二氧化硫排污放应主要发挥中央政府的作用，尤其应重视采取阶梯式征收排污费等经济措施，以激发排污电厂脱硫的积极性。

循环流化床锅炉燃烧脱硫要求在温度830℃~ 875℃床锅炉中燃烧,在这个温度范围内运行,飞灰含碳量大,影响燃烧效率。本文提对循环流化床燃烧温度进行了研究。     

On measuring the wealth of nations: the US economy, 1964-2001

This paper examines the methodology of Shaikh and Tonak (Measuringthe Wealth of Nations, 1994) underlying their calculation ofestimates of productive labour in the US economy from 1964 to2001. The focus is not on the results but on the methods thatgenerate them. The paper finds that the compromises made byShaikh and Tonak because of data unavailability are unreliable,and that better approximations are possible. On this latterbasis, the Shaikh and Tonak methodology can be used to providethe labour and wage estimates needed for empirical investigationsin the surplus-based tradition.

Increasing returns to savings and wealth inequality

In this paper I present an explanation to the fact that in the data wealth is substantially more concentrated than income. Starting from the observation that the composition of households' portfolios changes towards a larger share of high-yield assets as the level of net worth increases, I first use data on historical asset returns and portfolio composition by wealth level to construct an empirical return function. I then augment an Overlapping Generation version of the standard neoclassical growth model with idiosyncratic labor income risk and missing insurance markets to allow for returns on savings to be increasing in the level of accumulated assets. The quantitative properties of the model are examined and show that an empirically plausible difference between the return faced by poor and wealthy agents is able to generate a substantial increase in wealth inequality compared to the basic model, enough to match the Gini index and all but the top 1 percentile of the US distribution of wealth.     

惯例经济到法制经济--从WTO的基本要求谈起

当前我们要建设规范的制度化的市场经济，重要的一点就是要促使我们的市场经济尽快实现从惯例经济到法制经济的过渡，而这与WTO的基本要求即开放市场，遵守规则是相符的。从惯例经济到法制经济的过渡是一种社会历史的进步，尽快实现这种过渡能促使我们从WTO中谋取更多的利益，而只有按照WTO的基本要求去做，才能更快地实现这种过渡。     

Smoking,wealth accumulation and the propensity to plan

We investigate the relationship between wealth, smoking, and individual propensities to plan. Planning propensity affects wealth but not smoking, suggesting that planning is not an all-purpose skill. Financial planning may draw on different abilities than those that facilitate smoking cessation.     

从国际比较看中国发展循环经济的机制建构与路径选择

当今世界,不论是发达的工业化强国还是新兴的工业化国家,都把发展循环型经济、建立循环型社会看作是实施可持续发展战略的重要途径和实现形式。国际经验表明,发展循环经济,社会机制建构是关键。中国循环经济的社会发展机制建构包括:宏观调控机制的建构、激励驱动机制的建构、社会参与机制的建构等。     

A systems approach to the relationship between consumption and wealth

The single-equation approach to the determination of consumption, due to Hendry and von Ungern-Sternberg (HUS), is extended to a multi-equation system which links decisions on consumption and the components of wealth. The original HUS approach has proved to be a very durable one, being applicable to a number of countries and macroeconomic models. This approach is extended to allow a role for rates of return as well as income, and it is shown how this extension results in an error correction system. The empirical analysis used is based on Johansen's maximum likelihood extension of the co-integration approach of Engle and Granger.     

Shareholder wealth responses to European legislation on bank executive compensation

This paper uses an event study approach to investigate the shareholder wealth responses to European legislation on bank executive compensation. Using a sample of 124 banks over 2009–2010 and over 20 legislative and related events, we find that in early stages bank shareholders react positively to broad discussion at the EU level on executive pay. When plans to regulate the pay process are considered, however, this results in a negative stockholder reaction. We also find that large bank shareholders are most affected by remuneration policy.     

Introduction to the share economy

This paper introduces the major ideas in Martin Weitzman's The Share Economy. It notes that a “share” economy is one in which the marginal cost of labor is less than the average cost of labor; moreover, this condition can be induced by sharing revenues or profits. According to share theory, such contracts will lead firms to create more vacancies and thereby lower the average unemployment rate. Weitzman proposes to induce more share arrangements by giving a tax preference to share-type income.
