外来者劣势与海外并购企业的生产率提升

海外并购已成为新兴经济体企业对外投资和实现国际化扩张的重要战略选择。外来者劣势是中国企业海外并购活动面临着的诸多困难之一。“外来者”身份会对企业并购后的整合与生产率提升这一关键问题产生负面影响,化解负面影响需作深入的细化研究。选取2008-2015年中国上市企业共计197起海外并购事件,以制度距离、文化距离以及地理距离分别作为外来者劣势中合法性缺失和信息不对称的替代变量,分析外来者劣势对海外并购企业生产率提升的作用机制。结果显示,合法性缺失导致的外来者劣势对海外并购企业的生产率提升有显著负影响,但信息不对称对生产率的影响并不显著。调节效应检验结果表明,国内投资能显著弱化制度距离和文化距离引致的外来者劣势对海外并购企业生产率的负影响,国际化经验和出口能克服制度距离带来的合法性问题,但对文化距离带来的合法性缺失的弱化效果并不明显。     

Consumer engagement behaviors in the online wildlife trade: Implications for conservationists

This study investigates consumer engagement behaviors in the online wildlife trade, drawing implications for conservationists. The first study undertook a quantitative content analysis of 500 Facebook posts in wildlife trade lateral exchange markets to show how creative strategies, media type and persuasion tactics influence the number of likes and comments that posts receive. The second study then undertook a thematic discourse analysis to develop a rich understanding of the culture, beliefs and motivations that influence how consumers engage in the markets. Findings showed that an overwhelming majority of posts use a functional or informational strategy and that when posts use overt persuasion tactics the number of comments decrease. A conceptual model of how cultural factors may impact the success of marketing strategies is then proposed. These findings have implications for conservationists who seek to build engagement with wildlife trade consumers online.     

When profession trumps potential: The moderating role of professional identification in employees’ reactions to talent management

Abstract

This study aimed to investigate the role that a professionalized context plays in shaping employee reactions to talent management decisions. We examined the mediating role of felt obligation in the relationship between talent ratings and organizational citizenship behavior. Further, the study tested whether professional identification moderates the relationship between talent ratings and felt obligation towards the organization. Five hundred and ninety-eight teachers that had recently received ratings of their talent status responded to a survey questionnaire. Felt obligation mediated the relationship between talent ratings and organizational citizenship behavior. Furthermore, professional identification moderated the relationship between ratings of potential and felt obligation in such a way that the relationship was strongest for the teachers expressing the lowest professional identification. At high levels of professional identification, the relationship was not significant. These results indicate that conventional talent management might be less effective for increasing favorable attitudes and behaviors among employees in highly professionalized contexts, such as the education sector.     

How does the availability and use of flexible leave influence the employer–employee relationship?

In this article, we develop, and empirically test, a moderated mediation model of the effects of flexible leave on employees' organizational attachment. Drawing on a social exchange framework and signaling theory, we explore how the material and non-material nature of exchange between the employer and employee shapes their relationship. First, we show that the relationship between the availability of flexible leave and organizational attachment is shaped by two competing mediators, perceived organizational support (POS) and perceived flexibility stigma. Second, we delineate between availability and use of the policy, to show how the effect of POS is enhanced and perceived flexibility stigma reduced, with use. Our findings demonstrate that the relationship between the availability of flexible leave and organizational attachment is complex, but is enhanced through use of flexible leave. We contribute toward HRM scholarship about the relationship between employees' experience of HR practices and their corresponding impact on employees' subsequent behavior.     

The effect of oil price shocks on asset markets: Evidence from oil inventory news

We quantify the reaction of U.S. equity, bond futures, and exchange rate returns to oil price shocks driven by oil inventory news. Across most sectors, equity prices decrease in response to higher oil prices before the 2007/2008 crisis but increase after it. Positive oil price shocks cause a depreciation of the U.S. dollar against a broad range of currencies but have only a modest effect on bond futures returns. The evidence suggests that changes in risk premia help to explain the time-varying effect of oil price shocks on U.S. equity returns.     

Effects of CSR on affective organizational commitment via organizational justice and organization-based self-esteem

This study examined how employee perceptions of corporate social responsibility (CSR) influenced their affective organizational commitment (AOC) via procedural justice and organization-based self-esteem (OBSE). Using survey data collected from 203 employees working for a hospitality company, hypotheses were tested using structural equation modeling. The results showed that economic and philanthropic CSR did not have significant effects on procedural justice, but had significant direct effects on AOC. The findings also showed that procedural justice had a significant effect on OBSE, and both procedural justice and OBSE had significant effects on AOC. In addition, the results suggested that ethical CSR programs can have a positive impact on employees’ AOC via their procedural justice and OBSE. This study contributed to the literature by developing a CSR-procedural justice-OBSE-AOC model, guided by social exchange and self-consistency theories, and empirically testing it within a hospitality context.

On the robustness of the competitive equilibrium: Utility-improvements and equilibrium points

We show that the set of competitive equilibrium points of a pure exchange economy are the equilibrium points of a broader class of better-response demands than the usual utility-maximizing demand functions. The better-response demands are derived from assigning weights to all commodity bundles with higher utility than the current commodity bundle, with the greatest weights being placed on the commodity bundles with the highest utility gain. The usual utility-maximizing demand functions are then those in which the weight on the utility-maximizing bundle is one. We also show that these better-response demands belong to a large class of response maps that are generated by monotonic transformations of the utility functions and/or monotonic transformations of the weights assigned to the commodity bundles.     

Investigating first‐stage exchange rate pass‐through: Sectoral and macro evidence from euro area countries

In this paper, we evaluate the first‐stage pass‐through, namely the responsiveness of import prices to the exchange rate changes, for a sample of euro area (EA) countries. Our study aimed to shed further light on the role of microeconomic factors versus macroeconomic factors in influencing the extent of the exchange rate pass‐through (ERPT). As a first step, we conduct a sectoral analysis using disaggregated import prices data. We find a much higher degree of pass‐through for more homogeneous goods and commodities, such as oil and raw materials, than for highly differentiated manufactured products, such as machinery and transport equipment. Our results confirm that cross‐country differences in pass‐through rates may be due to divergences in the product composition of imports. The higher share of imports from sectors with lower degrees of pass‐through, the lower ERPT for an economy will be. In a next step, we investigate for the impact of some macroeconomics factors or common events experienced by EA members on the extent of pass‐through. Using the system generalised method of moments within a dynamic panel‐data model, our estimates indicate that decline of import‐price sensitivity to the exchange rate is not significant since the introduction of the single currency. Our findings suggest instead that the weakness of the euro during the first 3 years of the monetary union significantly raised the extent of the ERPT. This outcome could explain why the sensitivity of import prices has not fallen since 1999. We also point out a significant role played by the inflation in the Eurozone, as the responsiveness of import prices to exchange rate fluctuations tends to decline in a low and more stable inflation environment. Overall, our findings support the view that the extent of pass‐through is comprised of both macro‐ and microeconomic aspects that policymakers should take into account.     

Positive asymmetric information in volatile environments: The black market dollar and sovereign bond yields in Venezuela

PurposeWe test the informational efficiency of Venezuelan USD sovereign bond yields when the black market exchange-rate premium (BMERP) changes.DesignWe use a non-parametric, asymmetric, Granger causality test to test our hypothesis.FindingsWe find that the bond market with less than or equal to 5 years of maturity seems to be efficient when good news is released on the BMERP. However, this market is not informationally efficient, and when combined with unbiased bad news regarding the BMERP, arbitrage opportunities are created.Originality/valueCapital controls that restrict free exchange-rate mechanisms create arbitrage opportunities with negative news as opposed to positive news.
