The determinants of market-wide issue cycles for initial public offerings

This paper identifies the determinants of market-wide issue cycles for initial public offerings (IPOs) using an autoregressive conditional count model. We consider whether IPO volume is related to business conditions, investor sentiment, and time variation in adverse selection costs caused by asymmetric information between managers and investors. We provide evidence indicating that time variation in business conditions and investor sentiment are important determinants of monthly issue activity. By contrast, time variation in adverse selection costs does not significantly affect IPO volume.     

¿Hay evidencia de ciclo político-económico en el empleo sectorial de México, 1998-2013?

This paper looks for evidence of political-business cycles associated to the presidential elections in the Mexican sectorial employment over the period 1998-2013. By estimating panel data models, and controlling for the effects of the major determinants of employment, no evidence consistent with the predictions of the theoretical opportunistic model is found, i.e. whereas employment shows an expansion before and during the elections periods, the estimates are neither statistically significant nor robust. Furthermore, employment does not experience contractions after the elections or the office taking periods. Notwithstanding, the evidence suggests that employment is positively and negatively affected by output and real wages, respectively.     

Economic integration,economic crises and economic cycles in Mexico

This article analyzes the peculiarity of the dynamics of economic fluctuations of the Mexican economy, within the framework of its integration with the US and Canada; the article demonstrates how the Mexican economy make endogenous the macroeconomic crises from the USA (2001 and 2007), and how the business cycles of both countries became more aligned to each other.Based on the heterodox economic theory of crises and cycles, we check the “empirical law of economic dynamics” of the Mexican capitalist system according to the logic of the multiplier–accelerator theory that allowed us to study the dynamics of business cycles for the period of the study (1993–2013). To do this, we construct and estimate a stationary VAR model and utilize the Granger causality tests and quarterly data.     

Rational Inattention in Uncertain Business Cycles

The paper proposes endogenous information choice as a channel through which uncertainty affects price dynamics. I consider a rational inattention model with volatility uncertainty and endogenous information processing capability. According to the model, firms' learning and optimal attention exhibits inertia and asymmetry in response to volatility changes. Firms choose to process more information when uncertainty rises, especially about aggregate conditions, and their pricing behavior changes accordingly. Using a Markov‐switching factor‐augmented vector autoregression (MS‐FAVAR), the paper also documents a significant positive correlation between volatility and firms' responsiveness to macro‐ and microlevel shocks, consistent with model predictions.     

Factors contributing to business actions in response to climate change in Korea

Climate change is a growing problem and has been highlighted as a global issue. Empirical evidence increasingly indicates its obvious potential risks to humans and society. As members of this society, business organizations face greatly diverse climate change-related risks that they must recognize and respond to. However, gaps exist between scientific evidence and the actions of business organizations. Few empirical studies have examined the business organizations’ actions taken in response to climate change in Korea. This paper addresses this critical gap in the climate change literature by examining business organizations’ behaviors and identifying the factors influencing their actions. We employ statistical models to compare corporate climate change actions, and we explain their variations using survey data. The results indicate that despite increasing concerns about climate change, businesses have implemented very limited precautionary mitigation and adaptation actions. In addition, the concerns of the businesses about future climate change impact, organizational capacity (leadership, staff capacity, existence of a relevant division or department), and business size are significant factors with respect to the implementation of climate change actions.     

Validity and Reliability of Satisfaction as a Mediator between Quality Constructs in Manufacturer–Supplier Relationships Through Time and Across Contexts

Purpose: The main objective is to test and assess a research model through time and across contexts in which satisfaction is a mediator between quality constructs in manufacturer–supplier relationships. Satisfaction is positioned as a mediator between trust and commitment (i.e., causes) on the one hand, and cooperation, coordination and continuity expectancy (i.e., outcomes) on the other. The objective is also to provide a substantiation and contribution through time and across contexts, to business theory of supplier-manufacturer relationships

Methodology/approach: One out of eight samples selected for additional empirical substantiation for this study comprises a total of 600 small and medium-sized Spanish enterprises from various industrial sectors. A total of 259 usable questionnaires were returned, generating a response rate of 43.2%. The study is positioned (and compared) in relation to seven other samples that have been tested within the same research model in Canada, Finland, Norway (twice), South Africa, Sweden, and Taiwan. The total number of useable questionnaires is 1641, the average number of useable questionnaires per study is 205 and the average response rate is 37.4% in the studies assessed of this article.

Findings: The research model tested and assessed in the eight studies meets the requirements for satisfactory convergent, discriminant and nomological validity, as well as for construct reliability. The measurement and structural metrics support validity and reliability over time and across contexts, which is rare in marketing research.

Research implications: The theoretical framework contributes, through time and across contexts, to the business theory of supplier–manufacturer relationships. The tested research model demonstrates properties of validity and reliability across countries and company sizes. Implications and suggestions for further research are provided.

Practical implications: The empirical findings indicate key factors that contribute to satisfaction in manufacturer–supplier relationships in different countries and companies.

Originality/value: The article makes a contribution to theory relating to supplier–manufacturer relationships, providing evidence that the tested, hypothesized relationships are generally applicable. The validation or falsification of empirical findings in previous research is crucial in building valid and reliable theory over time and across contexts. Otherwise, theory becomes fragmented and undermines the credibility of marketing research.     

基于双重属性的商业模式构念化与研究框架建议

商业模式是创业研究的新兴主题,既有研究文献增长迅猛,但研究结论高度零散、矛盾甚至冲突,不少学者认为缺乏概念明确性是导致商业模式研究喧嚣混沌状况的根源,但鲜有研究对此做出积极的理论探索。本文首先梳理并提炼商业模式概念的演变及其理论逻辑,发现既有研究的不足并提炼商业模式如何创造价值的架构属性,基于不同理论视角形成了不同的概念维度,特别是对于商业模式如何塑造竞争优势的价值属性研究不足。进一步地,本文构建了基于双重属性的商业模式构念化与分类模型,目的在于整合并澄清学术界对于商业模式概念的学理性认识,同时基于该模型重新审视商业模式研究框架并提出未来研究亟待关注的关键问题,以期对商业模式形成、调整及其效应机制的理论发展和实证检验起到推动作用,最后提出了国内学者开展商业模式研究的启示和建议。

着重探讨了价值模块整合双元性对物联网商业模式的影响,分析了利用性价值模块整合和探索性价值模块整合两类相互冲突的活动在物联网商业模式构建过程中的可能关系。利用来自142家企业的问卷调查数据,运用层次回归分析方法检验了相关假设。结果显示:价值模块整合双元性的组合维(利用性价值模块整合与探索性价值模块整合的交互)对物联网商业模式具有显著的正向影响;网络嵌入强化了价值模块整合双元性的平衡维(利用性价值模块整合与探索性价值模块整合的平衡)对物联网商业模式的影响。
