Acquiring control in emerging markets: Foreign acquisitions in Eastern Europe and the effect on shareholder wealth

This paper examines stock market reaction to cross-border acquisition announcements that involve Eastern European emerging-market targets. Using a unique and a manually collected dataset, we identify 125 cross-border acquisitions in which developed-market firms from France, Germany, Netherlands, and the United Kingdom acquire ownership stakes in emerging as well as developed-markets in Europe during the period January 2000 through December 2011. In line with previous findings on foreign cross-border merger and acquisitions (M&As) in emerging-markets, evidence suggests that when the target firm is located in either the Czech-Republic, Hungary, Poland, or Russia, cumulative abnormal return (CAR) to the acquiring developed-market firm shows a statistically significant increase of 1.26% over a three day event window, following the announcement. Thereby, the relative size of the acquirer to the target appears to be the only significant factor that contributes to positive acquirer returns. The result is robust to the inclusion of controls for country, industry, as well as acquirer, target, and firm specific characteristics. Moreover, cross-border M&As involving an emerging-market target result in higher value creation for the acquiring shareholders than cross-border transactions into developed-markets.     

The impact of product market competition on training provision: Evidence from Canada

While standard models of training focus on how input market affects firms' training decisions, this paper investigates the impact of product market competition on training provision. Using the longitudinal data from Statistics Canada's Workplace and Employee Survey, we find that increased competition is strongly associated with more training provision. This association is unlikely to be driven by unobserved heterogeneity, specific measures used and other relevant factors. To the extent that training is a significant source of human capital and industry competitiveness, our results suggest that increasing training is an important channel through which competition raises productivity.     

我国企业海外并购提升了公司价值吗——以吉利并购沃尔沃为例

汽车企业海外并购有利于谋求市场和技术,实现全球资源配置和新的利润增长点。以吉利汽车并购沃尔沃汽车这一特有的"蛇吞象"式海外并购事件为例,从市场反应和财务绩效两方面来研究吉利并购沃尔沃能否提升公司价值:从市场反应发现其累积超常收益率并没有跑赢市场;从财务指标变动趋势发现,盈利能力并不稳健,成长能力逐年减弱,风险水平比较高,长期来看将会使股东的财富受到损失。最后从微观和宏观层面上对我国海外并购提出几点建议。     

从基尼系数看M2与GDP的合理比例

基尼系数和GDP/M2都可以看作是衡量收入分配的指标。通过一元线性回归分析,可以建立两者之间的关系函数,并能从中看出,要维持基尼系数的值在国际标准内,GDP/M2也应该保持在一定区间,为此,需要维持权力系统的内部制衡。     

Tourists' spending and adherence to shopping plans: The case of the christmas market in Merano,Italy

The present paper investigates the determinants of tourists' expenditure by categorizing tourists based on their mental budgets. Individuals can be divided into three categories based on the difference between their mental budget and actual expenditure: underspenders, on-budget spenders, and overspenders. Estimation of the empirical model is performed based on data collected through a survey of visitors to the Christmas Market in Merano, Italy during Advent in 2011. The estimation is performed with the Heckman estimator, ordered probit selection rule, and linear regression. We find that the spending patterns of visitors belonging to the three identified categories differ significantly. Analyzing visitors’ expenditure based on the proposed categorization allows us to identify category-specific factors and develop management strategies for each category. The managerial and theoretical implications of the results are discussed.     

The impact of board capital and board characteristics on firm performance

The purpose of this study is to investigate the effects of board capital on the relationship between CEO duality, board dependence, managerial share ownership and performance. We argue that board capital (the ability of board members to perform manager-monitoring activities and to provide advice and counsel to management) varies across board members. Highly qualified board members will be better at monitoring management and constitute a more valuable resource for firms. Based on a sample of U.S. companies listed in the Compustat S&P 500 and using both resource dependence and agency theories, we predict and find that CEO duality and board dependence negatively affect performance and that board capital mitigates the negative effects. We also predict and find that managerial share ownership positively affects performance and that board capital strengthens this positive relationship. The results are consistent with the view that firms benefit from board capital in terms of outside directors' ability to monitor managers and provide advice and counsel to managers.     

Business Life Cycle and Capital Structure: Evidence from Chinese Manufacturing Firms

This paper uses a panel data‐fixed effect approach and data collected from Chinese public manufacturing firms between 1999 and 2011 to investigate the impacts of business life cycle stages on capital structure. We find that cash flow patterns capture more information on business life cycle stages than firm age and have a stronger impact on capital structure decision‐making. We also find that the adjustment speed of capital structure varies significantly across life cycle stages and that non‐sequential transitions over life cycle stages play an important role in the determination of capital structure. Our study indicates that it is important for policy‐makers to ensure that products and financial markets are well‐balanced.     

Small Firms and the Strategy of the First Mover

Timing of entry and the decision to be a leader or follower in products or markets is a complex decision and empirical evidence suggests that first movers do not always 'capture' all the potential benefits from being first. Small firms in particular are faced with problems when deciding on whether to be a first or later mover. Their strategies were examined using a sample of 264 firms in chosen industry sectors and specific external and internal factors were found to explain much of the variation in timing of entry strategies by these firms. In particular a composite measure of the technological turbulence that firms faced in their supply chain was seen as a crucial determinant of early entry whilst uncertainty as to general business conditions explained much of the late and non pioneering strategies. Even within this group of small firms, size also played an important role with the smallest companies tending to be the most pioneering
