控制权性质影响税收敏感性吗?——基于企业劳动力需求的检验

西方学者研究表明企业所得税是劳动力需求的重要影响因素,这一理论在中国是否适用?中国大部分上市公司为国有控股企业,这一特殊的制度背景是否会影响企业所得税与劳动力需求的关系?本文基于2007年企业所得税改革这一外生政策变化,在检验西方企业所得税与劳动力需求关系的理论在中国是否适用的基础上,就不同控制权的性质是否会影响企业劳动力需求的税收敏感性进行了检验。研究发现企业所得税税率降低和"就业税盾"增加提高了企业劳动力需求,但这种税率和"就业税盾"的变化对国有控股企业劳动力需求变化的影响要显著小于非国有控股企业。这表明税收是影响企业劳动力需求的重要因素,但国有控制权使得这种税收敏感性变弱。本文的研究结果不仅丰富了相关领域的国际学术文献,而且对我国就业政策的制定具有政策含义。     

A model of multiple-unit ownership as a diffusion process

This paper develops and tests a new model for multiple-unit adoptions of durable goods based on the diffusion modeling tradition. Multiple-unit adoptions are a major component of sales for many consumer durable product categories. For instance, sales of multiple-unit adoptions for televisions have been higher than both first adoptions and replacement purchases since 1977, while for automobiles, they have represented more than 20% of sales since 1966 in Australia. The structural drivers of multiple-unit adoptions are quite different from either first purchase or replacement purchase. Hence, identifying and modeling the multiple-unit component of sales is important for aggregate sales forecasts. Moreover, consumer requirements for additional units of a product are likely to be considerably different than for the other components of sales (first purchases and replacement purchases). As such, the ratio of the first, multiple, and replacement sales components will strongly influence the product mix requirements of the market.

While forecasting and influencing multiple-unit sales are an important managerial issue, very little attention has been given to multiple-unit ownership in the diffusion modeling literature. The only model available was developed for the purpose of modeling relatively short-term behavior of multiple-unit adoptions, rather than the longer-term pattern of sales. We propose a model of multiple-unit adoptions as a diffusion process.

We apply the model to both color television and automobiles. Analysis of the model's long-term fit and forecasts in these applications provide support for the structure of the new model.     

"要素所有权"与"要素贡献"--论"按要素分配"问题的实质与衡量标准

我国实行的按生产要素分配，是根据不同生产要素的所有权关系，以及这些不同生产要素在财富的生产中所作的贡献产生的一种分配形式。“要素所有权”是生产方式的前提和起点，它决定生产资料和社会成员在各生产部门间的分配，是“按要素分配”原则存在的依据，“要素贡献”是按要素分配原则的最终决定因素。在按要素分配理论中，正确认识“要素所有权”与“要素贡献”两者间的内在联系和区别，是理解按生产要素分配问题的关键所在。     

股权结构、董事会治理与上市公司高管违规行为——我国上市公司高管人员"落马"现象的实证分析

本文采集了2004年1月～2006年1月期间公开披露高管人员违规落马现象的31家上市公司作为研究样本,通过逻辑回归模型对股权结构、董事会治理与上市公司高管违规行为进行了实证分析.研究表明,股权集中度与上市公司高管违规成显著正相关;董事会规模、高管薪酬、学历构成、内部人控制等因素与上市公司高管违规有显著相关关系.治理上市公司高管违规,应重点从股权结构和董事会治理上取得实效.     

The pricing of U.S. IPOs by seasoned foreign firms

We examine the pricing of U.S. initial public offerings (IPOs) by foreign firms that are already seasoned in their domestic countries. Presumably, these equity offers have less downside risk for investors than typical IPOs since domestic share prices can be used to help establish a preoffer value for the firm's equity. In spite of the presumed diminished downside risk, we find that offers by firms from countries that impose foreign ownership restrictions and capital controls are on average underpriced, experiencing an average first-day return in the United States of 12.7%. This result stems in part from the underwriter's failure to price the issue to fully reflect the postoffer premium that often arises for the U.S. shares. In contrast, offers by firms from countries without ownership restrictions have an average first-day return of 0.0%.     

股权结构的内生性：从我国基于控股股东的内部资本市场得到的证据

上市公司IPO时的股权结构是如何形成的?与先前文献只从业绩考察股权结构内生性不同的是,本文从基于控股股东的内部资本市场及其背后的利益动机出发,认为控股股东与上市公司IPO前的业务关联性、组织形式和产权性质等特征形成的内部资本市场,是上市公司IPO股权结构形成的主要影响因素。本文对1999—2004年IPO公司的研究有力地支持了上述假设。并且,股票发行制度改革前(国有企业、地方政府控制)相对于改革后(非国有企业、中央政府控制),其股权结构的形成更容易受政府干预和政策变化的影响,但很少受IPO前公司业绩的影响。这说明股票发行制度的改革确实有助于减少政府不合理干预,真正实现企业根据自身情况自主选择股权结构。     

上市公司股权结构与现金持有水平关系的实证分析

从公司治理视角出发,以中国上市公司为样本,对股权结构与企业现金持有决策关系进行了理论与实证分析.结果表明,经理人员持股比例、流通A股比例与企业现金持有水平显著正相关;法人股比例、股权集中度与企业现金持有水平显著负相关;第一大股东持股比例与企业现金持有水平正相关,但不显著;国有股比例与企业现金持有水平负相关,但极不显著.     

Insider Ownership and Firm Value: Evidence from Real Estate Investment Trusts

Real estate investment trust (REIT) provides a unique laboratory to study the relation between insider ownership and firm value. One, a REIT has to satisfy special regulations which weaken alternative mechanisms to control agency problems. Empirically, I find a significant and robust nonlinear relation between Tobin's Q and REIT insider ownership that is consistent with the trade-off between the incentive alignment and the entrenchment effect of insider ownership. Two, many REITs are Umbrella Partnership REITs (UPREITs) which have dual ownership structure. They have both common shares and Operating Partnership Units (OP units). Property owners can contribute their properties to the UPREIT in exchange for OP units. Their capital gains taxes remain deferred as long as they hold onto their OP units and the UPREIT does not sell the properties they contributed. OP units owners are locked in with the firm and have incentive to monitor firm management, but their interests diverge from the common shareholders because their tax bases are much lower. Consistent with the trade-off between positive monitoring effect of OP units and tax-induced agency costs, I find that UPREIT's firm value increases with the fraction of OP units, but the effect is significantly weaker for the UPREITs where insiders hold OP units.     

The impact of equity ownership groups on investment: Evidence from Ukraine

We empirically investigate the impact of different ownership groups on companies’ investment in Ukraine with a novel dynamic investment model where investment is based on present and historical levels of profitability (market-to-book value of equity) and lagged investment. Groups include state, insider, non-domestic, financial and financial and industrial group (FIG) ownership. Contrary to the literature, we find that the past level of profitability significantly affects investment; the majority presence of and increases in state ownership have a negative impact on firms’ investment, as is the case for non-domestic and financial companies’ ownership. Insider and FIG ownership have no impact on investment. We explain the results by the extent of liquidity concerns (hard and soft budget constraints), measured by cash flow interacted with a dummy variable of majority ownership of the respective group, and the extent of asset stripping for the corresponding ownership group and relate them to over- and under-investment, and to the free cash flow or cash constraint hypothesis.     

Private benefits from control block trades in the Spanish stock exchange

A control block trade can be explained by the expectation of financial gains, shared by all shareholders, or by the expectation of private benefits, exclusive to the buyer and possibly at the expense of other shareholders’ rents. The market for corporate control contributes to social welfare when it improves the efficiency of the allocation of resources. When the objective of a block transaction is private benefits, social welfare may be negatively impacted as minority shareholders could withdraw from the market. Therefore the estimation of private benefits would allow the efficiency of the market for corporate control to be assessed. Specifically, the aim of this paper is to calculate private benefits in the Spanish market for partial control. Using a sample of partial control transactions over the period 1990–2016, we find that the median of private benefits is negative, therefore it appears that there is no inefficient use of resources in the Spanish partial control market as a whole, however private costs are detected. The variability of private benefits is explained in a significant way by variables related to the control structure of the target firm, such as the controlling position of the buyer after the transaction, the contestability of control and the cross-shareholdings between the buyer and large shareholders. Performance and the size of the firm are significant as well.
