宣纸燎草制作技艺完善者曹裔生考略

稻草作为宣纸原料是在曹大三迁居小岭后,在发明宣纸制作技艺过程中,在经历近50年宣纸青檀皮制作技艺基本成熟后,为扩大再生产引入的,其时间约在1330年左右。燎草制作技艺体系作为一项独特发明,是宣纸技艺中最具本质、最具标志性的发明,经历了从始迁祖曹大三到第七世约近100年的时间,到明永乐、宣德年间形成了基本成熟的燎草制作技艺体系。自此,整个宣纸传统制作技艺体系基本完善。经初步研究,宣纸燎草制作技艺体系的完善者或关键性传承人是曹大三第七世曹裔生。

Capital Allocation: Evidence,Analytical Methods,and Assessment Guidance

Capital allocation is one of top management's primary responsibilities. Although always important, it is critical today because corporate operating returns on invested capital are at an all‐time high, while recent growth and investment have been modest, and corporate balance sheets in the U.S. have substantial cash. Yet few senior executives are sufficiently well‐versed in finance theory and methods to allocate capital as effectively as possible. Further, incentive programs that focus on meeting earnings per share often encourage behavior that is not in the best interests of long‐term shareholders. In this report, the authors begin with the premise that the goal of corporate capital allocation is to build long‐term value per share; and with that view in mind, they examine the main sources and uses of capital by the largest 1,500 U.S. companies during the last 30 years. More specifically, the authors identify the amounts of capital allocated to each of seven important alternatives, including major uses of capital such as M&Amp;A, capital expenditures, R&D, and distributions of capital to investors such as dividends and stock repurchases. And after reviewing the past allocations of capital to each of these alternatives, the authors summarize the academic research on the effects on corporate values of each of these uses of capital. The authors report that U.S. corporations fund most of their investments internally, and that M&Amp;A and capital expenditures have long been, and continue to be, the largest operating uses of capital, though both capital expenditures and growth in assets have fallen in recent years. At the same time, both corporate cash holdings and distributions to shareholders in the form of dividends and stock buybacks are at record levels. But even with such high payouts, R&D spending as a percentage of revenue by U.S. companies has remained high, and actually increased during the past decade. Finally, the authors provide a framework that can be used either internally or by outsiders to evaluate the capital allocation practices and effectiveness of a management team. This framework asks management to assess its past performance, provide realistic projections of future returns on invested capital, and evaluate their own incentive programs—all while renewing their commitment to the five principles of thoughtful capital allocation: (1) zero‐based capital allocation; (2) funding of strategies, not projects; (3) no capital rationing; (4) zero tolerance for bad growth; and (5) continuous monitoring of the value of all assets and business, and willingness to take action if and when such values are larger outside than inside the firm.     

Foreign direct investment and inequality: Evidence from China's policy change

In this paper, we examine the impact of foreign direct investment (FDI) on local urban inequality in China. Specifically, we consider the FDI policy change as an exogenous shock on the local labour markets. We find that cities that have experienced a bigger policy change in promoting FDI between 1997 and 2002 are significantly more unequal in 2005. This pattern is mainly driven by the positive association between FDI liberalisation and skill premia. The result holds after we control for other policy changes, such as privatisation of state-owned enterprises, infrastructure and trade liberalisation. We then turn to investigate the mechanisms using firm and individual-level information. Our firm-level evidence shows that FDI firms not only hire relatively more high-skilled workers but also provide relatively higher wages to high-skilled workers compared to domestic firms. Moreover, the individual-level analysis shows that FDI has a significantly positive spillover effect on wages received by skilled workers employed by state-owned enterprises, but not wages of unskilled workers.

How much does tax erode fund excess returns?

We model the tax drag from active fund management based on reported monthly holdings of active equity funds. Tax drag erodes 65 percent of the 0.74 percent excess return in Broad Market funds, but only 21 percent of the 1.80 percent excess return in Small-Cap funds for Australian superannuation (pension) fund investors. Tax drag varies with investment style; market state, which is most detrimental during bull markets; and fund turnover. For high-income individual investors, tax drag is exacerbated to the extent that active management only generates meaningful after-tax excess return for Small-Cap funds of certain styles.

土壤污染防治中央财政支出:现状与建议

土壤污染防治中央财政支出主要包括土壤污染监测、重金属污染防治、测土配方施肥、土壤有机质提升、实施土壤污染防治行动计划、农村环境连片整治等方面,近年来力度逐年加大,但仍存在财政投入不足、部门各自为战、污染责任追究不到位、社会参与激励政策缺失等问题。建议立法明确责任主体、加大财政投入力度、加强专项资金整合、设立土壤防治基金、实施财税优惠措施、引入污染防治PPP模式。
