This paper contributes to the home (market) bias literature where administrative or political borders limit trade across borders. Home bias is well documented at the national and subnational level. To sort out macro (e.g., location characteristics) and micro (e.g., enterprise characteristics) factors behind home bias, we use small and medium‐sized enterprise (SME) data from Vietnam. Using the fractional multinomial logit model, we find that the proportion of SME sales outside of their home markets is positively associated with enterprise size, age, number of business association memberships and the distance of SMEs' most important supplier. In contrast, the proportion of SME sales to neighbouring provinces is negatively associated with the share of SME production for final consumption. Besides enterprise‐level frictions, market characteristics matter too. The proportion of SME sales to customers in their home markets is negatively associated with home or neighbouring provinces' governance quality, while the proportion of sales to customers in neighbouring provinces is positively associated with these areas' governance quality. These suggest that good governance frees SME resources for use in selling to less familiar markets. 相似文献
This study examines the link between information spread by social media bots and stock trading. Based on a large sample of tweets mentioning 55 companies in the FTSE 100 composites, we find significant relations between bot tweets and stock returns, volatility, and trading volume at both daily and intraday levels. These results are also confirmed by an event study of stock response following abnormal increases in the volume of tweets. The findings are robust to various specifications, including controlling for traditional news channel, alternative measures of volatility, information flows in pretrading hours, and different measures of sentiment. 相似文献
Corporate sustainability is a dynamic, socially constructed concept. Relatedly, to understand the variations in the disclosure of corporate sustainability activities across countries, we need to inherently explore their underlying sociopolitical contexts. At present our understanding in this regard, is deficient. We respond to this extant research gap by adopting a multi‐country approach to investigate the relationship between countries' institutional environments and firms' sustainability disclosure (SD) practices, across six countries in the Southeast Asian region. Our findings reflect a common focus of Southeast Asian firms on community and human resources (HRs) related disclosures. Nevertheless, nuanced differences in their overall SD levels confirm the influence of differing legal, normative, and sociocultural systems in engendering greater disclosure and transparency at a national level. By quantifying the institutional environment and identifying external influencing factors, our study provides a useful framework grounded in neo‐institutional theory to widen the existing understanding of how institutional pressures can be measured and compared across different contexts. 相似文献
Purpose: The purpose of this study is to develop a model of motives and career choice based on learning styles in order to apply the model in teaching business. Although the relationship between learning and McClelland’s (1961) three motives (achievement, affiliation, and power) as confirmed that motives are “learned,” little research has examined if learning styles are the key factor to classify motivation into three different implicit motives and whether those motives affect students’ career choice.
Design: The article first examines the Kolb’s (Kolb, 1984, 1999; Kolb & Kolb, 2005) learning styles including active experimentation (AE), reflective observation (RO), abstract conceptualization (AC), and concrete experience (CE). It then measures the learning styles and Holland’s (1985) six career types including realistic, investigative, artistic, conventional, enterprising, and social by the three McClelland (1985) motives including achievement, power, and affiliation using Linguistic Inquiry and Word Count (LIWC) 2015 software (Pennebaker, Booth, Boyd, & Francis, 2015). Finally, the article compared the factors of learning styles and career types against each other based on the three motives in order to discuss the teaching strategies for students in their career choice.
Methodology: The study has used LIWC 2015 (Pennebaker et al., 2015) software to find the scores of achievement, power, and affiliation motives in the four Kolb’s learning styles (Kolb, 1984, 1999; Kolb & Kolb, 2005), and the six career interests (Holland, 1985). Correlation analysis was conducted among the motive values to find the relations among the learning styles, motives, and career choice.
Findings: (a) The two learning styles of AC and AE stimulate the need for achievement; (b) the learning style of RO stimulates the need for power; (c) the learning style of CE stimulates the need for affiliation; (d) people with a high achievement motive would be fit in artistic, investigative, and realistic careers; (e) people with a high power motive would be fit in conventional and enterprising careers; (f) people with a high affiliation motive would be fit in a social career.
Originality of the research: Efficient teaching techniques applied based on the study findings indicate that (a) teaching high achievement students will use more challenge techniques such as assignments and projects for thinking and doing training, (b) teaching high power students will use more control techniques such as discussions and presentations for observation training, and (c) teaching high affiliation students will use more socially oriented techniques such as writing tasks for emotion training. 相似文献
In Vietnam, women have poorer access to formal credit than men. This article determines the extent to which borrowing constraints restrict women’s access to formal credit and identifies the socioeconomic characteristics that determine formal credit discrimination. The study used secondary data from the Vietnam Access to Resources Household Survey (VARHS) published in 2013–14, and analysis was undertaken by econometric approaches such as logistic and multiple linear regression models and propensity score matching methods. The results show that among those participants who successfully obtained credit, approximately 85 per cent of women obtained less credit than men; and the amount of credit that women obtained was also less (on average, approximately 1.8 per cent less). Gender, number of years of schooling, marital status, participation in agricultural activities, off‐farm employment, and ownership of agricultural land for a male‐headed household positively influenced discrimination in obtaining credit and the amount of credit obtained. Moreover, the propensity score matching results found that the average increase in the credit obtained by males was 220,000 Vietnamese Dong (VND) and this is mainly due to discrimination in favour of men. The results suggest that policy action is needed to avoid discrimination in credit disbursement on the basis of gender. 相似文献
We examine the effect of herding behaviour on the credit quality of bank loans in Australia. We find that bank herding varies with different types of loans. It tends to be more prevalent in owner‐occupied housing loans and credit cards than other types of loans. During the global financial crisis period, herding in owner‐occupied housing loans was most pronounced due to the flight‐to‐quality phenomenon in the housing sector. Furthermore, we find that the big four banks tend to herd more than smaller and regional banks. Bank herding behaviour is countercyclical, as it is negatively related to real GDP growth and the cost of funding but is positively related to market risk. Regulatory capital requirements may also encourage herding as banks are required to hold less risk‐weighted capital for residential loans. Most importantly, bank herding is related to higher impaired assets and therefore lower loan quality. Our findings may have implications for policymakers and bank regulators. 相似文献
Background:Venous thromboembolism (VTE), comprised of deep vein thrombosis (DVT) and pulmonary embolism (PE), is commonly treated with a low-molecular-weight heparin such as enoxaparin plus a vitamin K antagonist (VKA) to prevent recurrence. Administration of enoxaparin?+?VKA is hampered by complexities of laboratory monitoring and frequent dose adjustments. Rivaroxaban, an orally administered anticoagulant, has been compared with enoxaparin?+?VKA in the EINSTEIN trials. The objective was to evaluate the cost-effectiveness of rivaroxaban compared with enoxaparin?+?VKA as anticoagulation treatment for acute, symptomatic, objectively-confirmed DVT or PE.Methods:A Markov model was built to evaluate the costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios associated with rivaroxaban compared to enoxaparin?+?VKA in adult patients treated for acute DVT or PE. All patients entered the model in the ‘on-treatment’ state upon commencement of oral rivaroxaban or enoxaparin?+?VKA for 3, 6, or 12 months. Transition probabilities were obtained from the EINSTEIN trials during treatment and published literature after treatment. A 3-month cycle length, US payer perspective ($2012), 5-year time horizon and a 3% annual discount rate were used.Results:Treatment with rivaroxaban cost $2,448 per-patient less and was associated with 0.0058 more QALYs compared with enoxaparin?+?VKA, making it a dominant economic strategy. Upon one-way sensitivity analysis, the model’s results were sensitive to the reduction in index VTE hospitalization length-of-stay associated with rivaroxaban compared with enoxaparin?+?VKA. At a willingness-to-pay threshold of $50,000/QALY, probabilistic sensitivity analysis showed rivaroxaban to be cost-effective compared with enoxaparin?+?VKA approximately 76% of the time.Limitations:The model did not account for the benefits associated with an oral and minimally invasive administration of rivaroxaban. ‘Real-world’ applicability is limited because data from the EINSTEIN trials were used in the model. Also, resource utilization and costs were based on the US healthcare system.Conclusion:Rivaroxaban is a cost-effective option for anticoagulation treatment of acute VTE patients. 相似文献
ABSTRACTThis paper proposes a hybrid collaboration recommendation method that accounts for research similarities and the previous research cooperation network. Research cooperation is measured by combining the collaboration time and the number of co-authors who already collaborated with at least one scientist. Research similarity is based on authors’ previous publications and academic events they attended. A weighted directed graph is built to discover new collaborators by using direct and indirect connections between scientists. Moreover, a consensus-based system is built to integrate bibliography data from different sources. The experimental results show that our method improves the recommendation performances over other methods. 相似文献
Eco‐innovations are an effective way for companies to strategically align themselves with customers’ growing environmental concerns. Despite their crucial role, scant research has focused on eco‐innovative product designs. Drawing from the sustainability and innovation literature, this article proposes that in the design of an eco‐innovation, its degree of innovativeness, level of eco‐friendliness, and detachability significantly affect consumers' adoption intentions. This article develops various conceptual models tested through three independent online experiments with U.S. consumers. The findings support the hypotheses and provide useful insights into the underlying mechanisms of how and why consumers respond to eco‐innovative product designs across various high‐tech product categories. Specifically, the results show (1) a positive effect of innovativeness degrees of eco‐innovative attributes on consumers' perceptions of product eco‐friendliness and on their adoption intentions as well as a significant moderating role of consumers' need for cognition (Study 1); (2) a positive influence of eco‐friendliness levels of eco‐innovative attributes on consumer adoption intentions in the case of high‐complexity products but not for low‐complexity products, emphasizing the need to adopt different approaches when developing eco‐innovations to ensure favorable consumer reactions (Study 2); and (3) a significant impact of the detachability of eco‐innovative attributes on consumers' perceptions of trade‐offs between environmental benefits and product functionality and on their intentions to adopt eco‐innovations (Study 3). These findings add to existing theoretical knowledge, provide actionable managerial implications, and identify fruitful avenues for future research. 相似文献
