The relationship of mentoring and network resources with career success in the Chinese organizational environment

The relationship of mentoring and network resources, the two components of social capital, with career success was investigated in a sample of 113 Chinese white-collar workers. The findings suggested that the prevalence of mentoring in the Chinese workplace is substantially higher than in the Anglo-Saxon workplace, and that Chinese employees do not distinguish their network ties or Guanxi into expressive and instrumental. These results were in line with the presumption that mentoring is an integral part of the Chinese culture and with the view that network ties or Guanxi in the Chinese society cannot exist in a purely instrumental form. In contrast to hypotheses, however, the findings suggest a limited relationship between social capital and career success. In particular, the amount of mentoring, participants reported they had received, was related to their intrinsic career success but not to their extrinsic career success; and the amount of network resources or Guanxi was related neither to extrinsic nor to intrinsic career success. These results were largely at odds with the accumulated knowledge on the benefits of social capital for career success. The findings are discussed with respect to the changing nature of the Chinese business and organizational environment, and their implications for human resource practices.     

An investigation on the attitudes of Chinese workers towards individually based performance-related reward systems

The study investigated the attitudes of Chinese workers towards individually based performance-related reward systems (IBPRRS). Participants were 106 white-collar workers employed in a Chinese new state-owned enterprise. In line with hypotheses, attitudes towards equality and equity-based rewarding were negatively and positively related, respectively, with attitudes towards IBPRRS. Also in line with expectations, both concern for loosing face (‘Mianzi’) and the belief that performance evaluations are affected by interpersonal relationships (‘Guanxi’) were negatively related to the attitude towards IBPRRS. However, in contrast to hypotheses, participants reported a more positive attitude towards equity than towards equality-based rewarding. Furthermore, in sharp contrast to the relevant hypothesis, the attitude of participants towards IBPRRS was positive. Ad hoc interviews with middle managers corroborated these findings and, furthermore, suggested that Guanxi and Mianzi were indeed impacting evaluations of performance, especially where there was an absence of objective performance criteria. The implication of the study is that although the views of Chinese employees towards IBPRRS are in principle positive, the cultural characteristics of China, and in particular Guanxi and Mianzi, must be taken into account for the successful design and functioning of such systems in the Chinese organizational context.     

International graduate students' perceptions and interest in international careers

This research developed and tested a comprehensive model of the antecedents of international graduate students' interest in an international career. Based largely on Social Cognitive Career Theory (SCCT), the model included elements that pertain to perceptions of external constraints (perceptions of the labor market, family pressure to return), international student experience (adjustment in the foreign country during graduate studies, exposure and immersion to the international context) and individual factors (self-efficacy with respect to working abroad and outcome expectancy). Participants were 139 international graduate students in the UK. Individual factors and perceived constraints were directly related to interest in an international career. The factors that comprised current international student experience were indirectly related to interest via their relationship with self-efficacy, while adjustment moderated the relationship between self-efficacy and interest. Although the hypothesized moderating role of family pressure to return did not materialize, the findings suggest that perceptions of constraints play a more substantial role in the formation of interest than has been assumed by SCCT theory thus far. The findings are discussed with respect to their implications for the literature and for the policies of host country stakeholders.     

Modeling the fiscal costs and benefits of alternative treatment strategies in the United Kingdom for chronic hepatitis C

Background: Hepatitis C (HCV) infection causes substantial direct health costs, but also impacts broader societal and governmental costs, such as tax revenue and social protection benefits. This study investigated the broader fiscal costs and benefits of curative interventions for chronic Hepatitis C (CHC) that allow individuals to avoid long-term HCV attributed health conditions.

Methods: A prospective cohort model, assessing the long-term fiscal consequences of policy decisions, was developed for HCV infected individuals, following the generational accounting analytic framework that combines age-specific lifetime gross taxes paid and governmental transfers received (i.e. healthcare and social support costs). The analysis assessed the burden of a theoretical cohort of untreated HCV infected patients with the alternative of treating these patients with a highly efficacious curative intervention (ledipasvir/sofosbuvir [LDV/SOF]). It also compared treating patients at all fibrosis stages (Stages F0–F4) compared to late treatment (Stage F4).

Results: Based on projected lifetime work activity and taxes paid, the treated cohort paid an additional £5,900 per patient compared to the untreated cohort. Lifetime government disability costs of £97,555 and £125,359 per patient for treated cohort vs no treatment cohort were estimated, respectively. Lifetime direct healthcare costs in the treated cohort were £32,235, compared to non-treated cohort of £26,424, with an incremental healthcare costs increase of £5,901 per patient. The benefit cost ratio (BCR) of total government benefits and savings relative to government treatment costs (including LDV/SOF) ranged from 1.8–5.6. Treating patients early resulted in 77% less disability costs, 43% lower healthcare costs, and 33% higher tax revenue.

Conclusion: The ability to cure Hepatitis C offers considerable fiscal benefits beyond direct medical costs and savings attributed to reduced disability costs, public allowances, and improved tax revenue. Changes in parameters, such as productivity, wage growth, and tax rates, can influence the conclusions described here.

Network modeling approaches for calculating wholesale NGA prices: A full comparison based on the Greek fixed broadband market

According to the European Commission Recommendation for setting copper and fiber wholesale prices where cost orientation is imposed as a remedy, National Regulatory Authorities (NRAs) should adopt a Bottom-UP Long-Run Incremental Cost Plus (BU LRIC+) costing methodology that estimates the current cost that a hypothetical efficient operator would incur to build a modern efficient Next Generation Access (NGA) network. The starting point of modeling an efficient operator investing in NGA networks is the network modeling approach. In this paper, we compare the most widely adopted network modeling approaches in terms of wholesale fiber-to-the-home (FTTH) prices. In particular, the modified scorched node approach is compared to the extreme cases of the scorched node and the scorched earth approaches. The comparison between the aforementioned scenarios sheds light on the impact of each approach on the wholesale FTTH prices. The main finding of this paper is that the scorched earth approach leads to a maximum of 10% reduction in the short-term access prices compared to the most inefficient scorched node approach, whereas further extending its optimizations by optimizing the number of central offices, both the short-term and long-term wholesale price reductions are quite significant (more than 20%) regardless of service speeds. Consequently, NRAs should consider a geographically differentiated modeling approach when regulating the wholesale market by adjusting the level of scorching in each area and network segment according to the investment plans of telecom operators. An appropriate variation of the modeled network operator's efficiency is expected to more accurately represent the costs of a reasonably efficient operator based on the real market conditions and a forward-looking perspective. These findings provide valuable information to both network operators and telecom regulators.     

The Association Between Operating Cash Flows and Dividend Changes: An Empirical Investigation

The Association between earnings and dividend changes has been established since Lintner's (1956) pioneering work. Subsequent research attempted to establish an association between operating cash flows and dividend changes, given earnings, without success (Simons, 1994). Recently, there has been increased attention in cash flow reporting. Regulatory bodies worldwide have stressed the significance of cash flow information in capital markets. Research on the association between cash flows and dividends has been limited, yielding inconclusive results. The purpose of this study is to re-evaluate and extend prior studies by examining the incremental ability of cash flows to explain dividend changes, given earnings. We argue that a positive relationship between cash flows and dividend changes should exist due to liquidity and accruals management considerations. The empirical evidence of this study supports that the dividend changes-cash flow relationship is significantly positive (a) when operating cash flows are low compared to earnings, and (b) when firm growth is moderate.     

Reverse stock splits and earnings performance

This paper presents evidence that reverse stock splits are preceded by significantly poorer earnings performance for splitting firms compared to a sample of matched control firms. Interestingly, the overall earnings-returns relationship becomes significantly stronger following the reverse stock split. I interpret this as evidence that reverse splits communicate to market participants that sub-par earnings performance before the split is not transitory and that it is expected to persist in the future. Together, the evidence in this paper provides an explanation as to why reverse splits, which are employed for reasons that are seemingly beneficial to shareholders, are assessed negatively, on balance, by market participants.     

Is there selection bias in laboratory experiments? The case of social and risk preferences

Laboratory experiments are frequently used to examine the nature of individuals’ social and risk preferences and inform economic theory. However, it is unknown whether the preferences of volunteer participants are representative of the population from which the participants are drawn, or whether they differ due to selection bias. To answer this question, we measured the preferences of 1,173 students in a classroom experiment using a trust game and a lottery choice task. Separately, we invited all students to participate in a laboratory experiment using common recruitment procedures. To evaluate whether there is selection bias, we compare the social and risk preferences of students who eventually participated in a laboratory experiment to those who did not, and find that they do not differ significantly. However, we also find that people who sent less in a trust game were more likely to participate in a laboratory experiment, and discuss possible explanations for this behavior.     

The formation of forward freight agreement rates in dry bulk shipping: Spot rates,risk premia,and heterogeneous expectations

We examine the formation of forward rates in the dry bulk shipping industry. We illustrate that the bulk of basis volatility can be attributed to expectations about future physical market conditions rather than expectations about future risk premia. However, there exists significant predictability of risk premia by both price-based signals and economic variables. To explain this finding, we develop a dynamic asset pricing framework where, apart from having different objective functions, agents might also differ in the way they form expectations about future market conditions. Accordingly, we argue that the average investor should hold “near-rational” but slightly contrarian beliefs.
