The Relation Between Financial and Tax Reporting Measures of Income

Abstract: We examine the magnitude and sources of difference between income for tax and financial reporting purposes using publicly available data from 1988 to 1998. We find evidence that the book-tax income spread has generally increased over time, but that a relatively small set of variables are able to explain this increase. We also find that these same variables explain a large percentage of the variation in the book-tax spread across firms. While neither supporting, nor disproving, the existence and growth in tax sheltering behavior, the results do suggest that financial statement-based measures of income have become less representative of firms' taxable income.

Photocatalysis: Basic Principles, Diverse Forms of Implementations and Emerging Scientific Opportunities

Abstract: Photocatalysis promises a solution to challenges associated with the intermittent nature of sunlight which is considered as renewable and ultimate energy source to power activities on Earth. This review aims to provide a broad overview of the field. Insight into natural photosynthesis is discussed first, which provides a scientific basis for most efforts on photocatalysis. Afterwards, the details of four existing types of photocatalysis are presented, namely photosynthesis by plants, photosynthesis by microalgae, photocatalysis by suspension and photoelectrocatalysis. Detailed analyses of simple photocatalysts and integrated photocatalytic systems are followed to shed light on the different functionalities of different components in a working photocatalyst. Special attention is given to the roles played by surface and interface chemical phenomena. Lastly, perspectives on artificial photosynthesis are discussed briefly at the end.

How Does Venture Capital Financing Improve Efficiency in Private Firms? A Look Beneath the Surface

Abstract: We use the Longitudinal Research Database (LRD) of the U.S. Census Bureau, which covers the entire universe of private and public U.S. manufacturing firms, to study several related questions regarding the efficiency gains generated by venture capital (VC) investment in private firms. First, do VCs indeed improve the efficiency (total factor productivity, TFP) of private firms, and if so, are certain kinds of VCs (high reputation vs. low reputation) better at generating such efficiency gains than others? Second, do VCs invest in more efficient firms to begin with (screening), or do they improve efficiency after investment (monitoring)? Third, do efficiency improvements due to VC backing arise from increases in sales or reductions in costs? Fourth, does VC backing and the associated efficiency gains affect the probability of a successful exit (IPO or acquisition)? Our analysis shows that the overall efficiency of VC-backed firms is higher than that of non-VC-backed firms at every point in time. This efficiency advantage of VC-backed firms arises from both screening and monitoring: the efficiency of VC-backed firms prior to receiving financing is higher than that of non-VC-backed firms, and further, the growth in efficiency subsequent to VC financing is greater for such firms. The above increases in efficiency of VC-backed firms are spread over the first two rounds of VC financing after which the TFP of such firms remains constant until exit. Additionally, we show that while the TFP of firms prior to receiving financing is lower for high-reputation VC-backed firms, the increase in TFP subsequent to financing is significantly greater for these firms, consistent with high-reputation VCs having greater monitoring ability. We disentangle the screening and monitoring effects of VC backing using three different methodologies: switching regression with endogenous switching, regression discontinuity analysis, and propensity score matching. We show that while overall efficiency gains generated by VC backing arise primarily from improvements in sales, the efficiency gains of high-reputation VC-backed firms arise also from lower increases in production costs. Finally, we show that VC-backing and the associated efficiency gains positively affect the probability of a successful exit.

The salience of 'culture's consequences' : The effects of cultural values on top executive commitment to the status quo

Abstract: While top executives are argued to play a central role in strategic adaptation, evidence suggests that they are not equally open to organizational change. This study extends earlier investigation of the determinants of top executive commitment to the status quo (CSQ) to the international arena, examining the influence of cultural values on executive open-mindedness toward change. Using data from a survey of top managers in 20 countries, analyses reveal that values of individualism, uncertainty avoidance, power distance, and long-term orientation are significantly related to executives’ adherence to existing strategy and leadership profiles. Further, while confirming earlier findings that industry tenure is positively related to strategy CSQ, results show that tenure does not significantly affect leadership CSQ once cultural values are controlled. In summary, the findings reveal that culture has an important impact on executive mindsets, as demonstrated by the fact that executives of differing cultural background are not equally open to change in organizational strategy and leadership profiles. Second, the findings suggest that executives’ views of appropriate leadership profiles reflect the imprint of cultural socialization moreso than professional experience. Finally, and more broadly, the study offers empirical support for the view that values figure prominently in shaping executives’ strategic and leadership orientations. © 1997 by John Wiley & Sons, Ltd
