We analyse why the Chinese government sets restrictions on foreign direct investment (FDI). We focus our analysis on the percentage of shares in relocated firms that the government allows to be foreign‐owned. The government's decision on this percentage depends on the entry cost, the number of firms that relocate and the weight of the consumer surplus in the objective function of the government. We show that by its choice of this percentage, the Chinese government may restrict or encourage FDI to its country. We also find that if the government may subsidise the fixed entry cost, it provides a subsidy only when the producer surplus has a greater weight than the consumer surplus in weighted welfare. In that case, the subsidy encourages relocation by both firms and permits the government to allow a lower percentage of shares to be foreign‐owned in relocated firms.  相似文献

This article provides the limit theory of real‐time dating algorithms for bubble detection that were suggested in Phillips, Wu, and Yu (PWY; International Economic Review 52 [2011], 201–26) and in a companion paper by the present authors (Phillips, Shi, and Yu, 2015; PSY; International Economic Review 56 [2015a], 1099–1134. Bubbles are modeled using mildly explosive bubble episodes that are embedded within longer periods where the data evolve as a stochastic trend, thereby capturing normal market behavior as well as exuberance and collapse. Both the PWY and PSY estimates rely on recursive right‐tailed unit root tests (each with a different recursive algorithm) that may be used in real time to locate the origination and collapse dates of bubbles. Under certain explicit conditions, the moving window detector of PSY is shown to be a consistent dating algorithm even in the presence of multiple bubbles. The other algorithms are consistent detectors for bubbles early in the sample and, under stronger conditions, for subsequent bubbles in some cases. These asymptotic results and accompanying simulations guide the practical implementation of the procedures. They indicate that the PSY moving window detector is more reliable than the PWY strategy, sequential application of the PWY procedure, and the CUSUM procedure.  相似文献

Investors globally prefer dividend‐paying stocks over nondividend‐paying stocks more in declining than in advancing markets, even accounting for firm‐level growth opportunities, size and risk effects. Dividend‐paying stocks outperform nondividend‐paying stocks, from 0.63% (China) to 3.79% (Canada) more per month in declining than in advancing markets. In declining markets, dividend‐paying firms outperform by more than any underperformance in advancing markets. The results are robust across dividend taxation regimes, legal environments, emerging and developed markets, periods prior to and after the 2008 global financial crisis, the exclusion of the dividend declaration month and in respect to segmented or integrated international capital markets.  相似文献

We use data from internal assessments of audit quality in a Big 4 firm to investigate the impact of audit firm tenure and auditor‐provided non‐audit services (NAS) on audit quality. We find that first‐year audits receive lower assessments of audit quality and that quality improves shortly thereafter and then declines as tenure becomes very long. Partitioning our sample between SEC registrants and private clients, we find that the decline in audit quality in the long tenure range is attributable to audits of private clients. For audits of SEC registrants, the probability of a high quality audit reaches its maximum with very long tenure. We also find that audit fees are discounted for first‐year audits but auditor effort is higher than in subsequent years. We find no association, on average, between total NAS fees and audit quality in the full sample but observe that total NAS fees are positively associated with quality for SEC registrants and negatively associated with quality for privately held clients. Our findings are important for regulatory policies related to audit firm tenure and auditor‐provided NAS.  相似文献

This research tests the role of perceived support from multinational corporations and host-country nationals for the adjustment of expatriates and their spouses while on international assignments. The investigation is carried out with matched data from 134 expatriates and their spouses based in foreign multinationals in Malaysia. The results highlight the different reliance on support providers that expatriates and their accompanying spouses found beneficial for acclimatizing to the host-country environment. Improved adjustment in turn was found to have positive effects on expatriates' performance. The research findings have implications for both international human resource management researchers and practitioners.  相似文献

This study explored whether the relationship between perceived training intensity and knowledge sharing is prone to combined moderating influences. We operationalized perceived training intensity as a challenge stressor, in accordance with the challenge‐hindrance framework of work stressors. The results of a study of 129 employees from three Norwegian service industries revealed a positive relationship between perceived training intensity and supervisor‐rated knowledge sharing for employees reporting high levels of perceived job autonomy and high levels of perceived supervisor support. In contrast, we found a negative relationship between perceived training intensity and supervisor‐rated knowledge sharing for employees reporting high levels of perceived job autonomy and low levels of perceived supervisor support. These findings suggest that supervisors are of vital importance in facilitating knowledge sharing among employees in settings where developmental challenges are prevalent and perceptions of job autonomy are high. Implications for future research and practice are also discussed. © 2014 Wiley Periodicals, Inc.  相似文献

The article determines pricing and order-up-to level S inventory decisions over an infinite planning horizon from the point of view of a risk-averse decision maker. The demand is assumed to be stochastic but influenced by the selling price which is a decision variable. Shortages are allowed and backordered partially. We calculate the present value of the cash flow over the entire planning horizon and incorporate the notion of risk aversion into the model using a concave utility function. We numerically demonstrate the model and investigate the impact of different model-parameters on the optimal decisions. It is observed that the optimal selling price for a risk-averse decision maker is not less than the optimal selling price of a risk-neutral decision maker while the optimal order level for the risk-averse decision maker is always less than that of the risk-neutral decision maker.  相似文献
