ABSTRACT

The paper probes into an antithetical aspect of China’s economic reforms in the global context by focusing on the recent developments of China’s intellectual property regime. By analyzing this cutting-edge legal system, it highlights China’s political divergence against its economic convergence in its decade-long reforms, in particular, its state-oriented innovation system as against the world’s neo-liberal economic order. The last decade witnessed China’s preeminent transformation from a passive follower to a proactive advocator of IP standards. However, certain entrenched limits characterizing China’s state-oriented economy and cultural systems such as information blockade and coercive technology transfer serve as catalysts that are apt to provoke acrimonious confrontation between China and major economies. In this sense, China’s incomplete reforms have taken on a new form: as China’s influence on the global economy grows, conflicts of diverse national priorities become more palpable than simple-minded economic cooperation.  相似文献

This field study examines the workings of multiple performance measurement systems (PMSs) used within and between a division and Headquarters (HQ) of a large European corporation. We explore how multiple PMSs arose within the multinational corporation. We first provide a first‐order analysis which explains how managers make sense of the multiplicity and show how an organization's PMSs may be subject to competing processes for control that result in varied systems, all seemingly functioning, but with different rationales and effects. We then provide a second‐order analysis based on a sense‐making perspective that highlights the importance of retrospective understandings of the organization's history and the importance of various legitimacy expectations to different parts of the multinational. Finally, we emphasize the role of social skill in sense‐making that enables the persistence of multiple systems and the absence of overt tensions and conflict within organizations.  相似文献

We investigate whether tax avoidance and manager diversion are complementary when the costs of diversion are low by comparing dividend payouts, performance, and overinvestments of tax haven firms versus other multinational firms based in countries with weak and strong investor protections. Desai and Dharmapala (2006, 2009a, b) and Desai et al. (2007) set forth a theory of tax avoidance within an agency framework (the D&D theory) based on the assumption that tax avoidance and manager diversion are complementary when the corporate governance system is “ineffective” (i.e., the manager's expected costs of diversion are low). Tax haven firms are corporate groups whose parent firms are incorporated in tax haven countries that are not the countries where the groups’ headquarters or primary operations are located (i.e., their “base” countries). We argue that tax haven incorporation potentially lowers the costs of diversion for managers of firms based in countries with weak investor protections. Using a sample from 28 base countries, we provide evidence that manager diversion and tax avoidance are complementary for tax haven firms based in countries with weak investor protections but not for tax haven firms based in countries with strong investor protections. Our results are consistent with the complementarity assumption underlying the D&D model and provide additional insights into the potential impact of the decentralization of the global firm.  相似文献

Demand for disclosures on environmental, social, and governance (ESG) issues has increased dramatically. Using corporate political spending disclosures as our setting, we conduct a detailed inquiry of 541 political spending‐related shareholder proposals from 2004 to 2012 to highlight the role of shareholder activism as a mechanism to motivate ESG disclosure. Unlike earlier studies, we examine both proposals that went to a vote and proposals that were withdrawn by the activist, allowing us to assess more comprehensively the success of shareholder activism. We find that 20 percent of firms targeted by disclosure proposals begin disclosing in the subsequent year, although implementation rates vary by proposal type—8 percent for proposals subject to a vote versus 56 percent for proposals withdrawn. The sponsor is also important: unions and public pension funds are less likely than other activists to target firms with agency problems and are less successful in having proposals withdrawn, and the implementations they obtain are viewed more negatively by the broader investor base. Our findings highlight shareholder proposals as one mechanism through which investors can successfully express their preferences for corporate disclosure policies. Given activists' long‐standing interest in environmental and social disclosure policies, we believe our findings generalize to a broader set of ESG disclosures.  相似文献

We gain unique insights into materiality judgments about accounting errors by examining SEC comment letter correspondence. We document that managers typically use multiple quantitative benchmarks in their materiality analyses, with earnings being the most common benchmark. In most of the cases we review, managers deem the error immaterial despite its exceeding the traditional “5 percent of earnings” rule of thumb, often in multiple periods and by a large degree. Instead of attempting to conceal these overages, managers tend to forthrightly acknowledge them, often asserting that the benchmark is abnormally low during the violation period. We find that 17–26 percent of these “low benchmark” assertions are suspect (although none of these “low benchmark” assertions are challenged by the SEC). We also document substantial variation in the extent to which qualitative factors are mentioned as considerations. The SEC generally is deferential toward managers' arguments and judgments but is more likely to challenge immateriality claims when managers admit there are qualitative factors that indicate errors are material.  相似文献

Previous studies have found evidence that experiencing a traumatic event during childhood or adolescence can interfere with the acquisition of human capital. Drawing on data from the National Longitudinal Study of Adolescent Health, we estimate the effects of being the victim of forced intercourse on the mental health, academic performance, and educational attainment of young women paying careful attention to the role of unobservables at the individual, family, and community levels. Our results suggest that forced intercourse is strongly related to depression. Moreover, there is evidence that the psychological damage caused by forced intercourse leads to reduced academic performance and educational attainment.  相似文献

Abstract

From 1949 through 1979, China had no insurance industry, as the state self-insured. Government policy was cautious and growth slow for the next 15 years, but since the early 1990s the pace of policy change has accelerated and the industry has grown at more than twice the gross domestic product. Nevertheless, the industry's development and market penetration, particularly in general insurance, remains extremely low by international standards, and continues to be retarded by a mix of forces. This paper examines the drivers for and against the long emergence of China's insurance industry, followed by a projection of the future development of the industry in China.  相似文献

We analyze exports along five margins to observe the changes of newly exported products, products removed from the export market, and continuously traded products to new, old, and exited destinations on export growth. We find export shares differ between developing and developed countries: 1) entering and exiting products are an important source of export value, but more so for developing than developed countries, 2) that continuously exported products to new destinations are a more important source of export value for developing than developed countries, 3) that though the removal of exiting products has a large impact on export value, the removal of products from one destination that continue to be exported elsewhere results in little loss to total export value, and 4) that larger and richer exporting countries have less opportunity to increase exports from new destinations than smaller and poorer exporting countries. Understanding the change in these margins across different types of countries may be important for formulating trade agreements and targeting of new trade partners.  相似文献
