Spillovers from foreign direct investment and firm growth: technological,financial and market structure effects

This article examines spillover effects from inward investment on domestic firm growth in the case of a developed host country. The emphasis is placed on the role of the technological gap between domestic and foreign firms in identifying the importance of technology diffusion from the presence of multinationals. An augmented production function is employed to account for technological, financial and market structure effects. Based on a sample of 2589 manufacturing firms operating in Greece between 1992 and 1997, the analysis provides evidence that the significance of spillovers varies with the relative technological position of domestic firms and is higher in the middle and upper quantiles of the growth distribution. It was estimated that a unit increase in the foreign presence in Greek industry raises output growth by 7% on average, in a five‐year period, after controlling for technological differences among firms. This result is consistent with the ‘absorptive capacity’ hypothesis that the technological capability of the host country relates positively to FDI spillover benefits.     

Separating uncertainty from heterogeneity in life cycle earnings

This paper develops and applies a method for decomposing crosssection variability of earnings into components that are forecastableat the time students decide to go to college (heterogeneity)and components that are unforecastable. About 60% of variabilityin returns to schooling is forecastable. This has importantimplications for using measured variability to price risk andpredict college attendance.

Exploring the multi-dimensionality of authenticity in dining experiences using online reviews

The quest for authenticity in dining experiences has become increasingly important. This paper explores authenticity dimensions that are of value to customers in dining experiences, and by that gains a multi-dimensional understanding of authenticity in this context. Following an integrated learning approach using text mining and classification techniques, this paper explores and confirms different dimensions of authenticity by identifying and classifying authenticity judgements in online restaurant reviews. The results suggest that authenticity is a multi-dimensional concept encompassing Authenticity of the Other, Authenticity of the Producer, and Authenticity of the Self as first-level dimensions. Additionally, besides historical and categorical authenticity which have been previously explored in the literature, a new type of authenticity - Deviated Authenticity - emerged as a second-level dimension falling under Authenticity of the Other. This paper enhances existing conceptualisations of authenticity and establishes avenues for exploring the multi-dimensionality of other consumer research concepts using user-generated content.     

New development: A new COFOG for South Korea

The South Korean government's Classification of the Functions of Government (COFOG) is grounded in the System of National Accounts (SNA), rather than Government Finance Statistics (GFS). This article explains why a GFS-based classification might be beneficial to South Korea for the purposes of fiscal management and the comparison of government expenditures with other countries.     

知识活动视角下企业大学类型及其支撑能力体系

基于知识视角，任何组织开展的活动均可视为知识活动。企业大学所从事的知识活动不仅包括知识转移活动，还包括知识创造活动和应用孵化活动，不同企业大学开展的知识活动不同，对以上3类知识活动的主导程度也不同。借鉴扎根分析流程，通过多案例研究梳理企业大学的里程碑事件，对企业大学的知识活动类型进行理论提炼并总结相应能力支撑体系。结果发现：①企业大学模式类型并不绝对而是多元的，随着企业大学知识活动的不断丰富和延伸，逐渐演化为不同模式类型;②知识转移活动并非是企业大学唯一的知识活动路径，不宜忽视企业大学知识活动的全息性特征;③企业大学为了更好地履行职能，还应树立支撑能力组合观念，尤其应该按照企业大学知识活动特性和规律构建相应关键能力支撑体系。     

How household food shopping behaviors changed during COVID-19 lockdown period: Evidence from Beijing,China

The COVID-19 pandemic has had a great impact on food shopping behavior. However, changes in food shopping behavior and related decision-making mechanisms remain unexplored. This study conducted a face-to-face questionnaire survey with 900 residents in three communities in Haidian, Beijing, China, to analyze food shopping behavior during the periods of pre-lockdown, lockdown (January–March 2020), and post-lockdown. Our results indicated that the preference for fresh food e-commerce shopping was accelerated by the lockdown with the usage rate increasing by 48%; the wet markets were seriously hit by the lockdown policy and had not fully recovered by the post-lockdown period (with a 75% reduction in the usage rate during lockdown). The psychological mechanisms of changes in food shopping behavior revealed that the context (e.g., community facilities) and the perceived risk of COVID-19 were two significant factors impacting the four shopping choices investigated. Specifically, the context factors affected behavior directly for supermarkets and convenience stores and indirectly for e-commerce and wet markets. The findings are expected to help in guiding emergency responses during a future pandemic as well as the long-term construction of food supply facilities.

Transferring knowledge across sub-genres of the ABC implementation literature

In the last decade, a continuous stream of empirical articles has investigated how various implementation process factors (including, top management support, adequate resources, and ABC training) influence ABC implementation success. However, at the same time, a growing number of researchers have criticised this ‘mainstream approach’ for, among other things, neglecting issues of power and politics and for viewing ABC implementations as something inherently positive. Based on Lukka and Granlund's [Lukka, K., Granlund, M., 2002. The fragmented communication structure within the accounting academia: the case of activity-based costing research genres. Acc. Organ. Soc. 27, 165–190] call for communication between various streams of ABC research, the purpose of this paper is to discuss how the ‘mainstream’ implementation literature may benefit from insights made in the politically oriented literature. A key conclusion is that such an analysis not only provides us with enriched explanations of the relatively strong and coherent findings in the ‘mainstream’ ABC implementation literature, but has also the potential to explain ‘unexpected’ and ‘contradictory’ results found in this stream of research. Based on these observations, a number of directions for future research are proposed.
