Bank mergers and acquisitions in emerging markets: evidence from Asia and Latin America

Following a global wave of consolidation in the banking industry, this study analyses 132 mergers and acquisitions (M&As) involving banks in emerging markets in Asia and Latin America between 1998 and 2009. An event study measures the change in shareholder value for acquirers and targets; and a multivariate regression identifies the drivers of the change in shareholder value for acquirers. On average M&As create shareholder value for target firms, while acquirer firms do not lose shareholder value. Geographical diversification creates shareholder value for acquirers. Acquirer shareholders benefit from the acquisition of underperforming targets; from transactions settled by cash rather than exchange of equity; and from government-instigated M&A transactions.     

A nonlinear long memory model, with an application to US unemployment

Two important empirical features of US unemployment are that shocks to the series seem rather persistent and that it seems to rise faster during recessions than that it falls during expansions. To jointly capture these features of long memory and nonlinearity, we put forward a new time series model and evaluate its empirical performance. We find that the model describes the data rather well and that it outperforms related competitive models on various measures of fit.     

论“公正”重于“关护”———对中国就业弱势群体税收支持政策的哲学反思

随着我国就业弱势群体的出现,财政部和国家税务总局陆续出台了一系列促进就业的税收政策,但由于这些税收政策在“公正”与“关护”两个基本原则运用上存在侧重点的偏差,导致这些政策的作用效果并不明显。“公正”与“关护”同属人类伦理学理论资源中的两个基本道德诉求。在就业弱势群体税收支持政策制定中,两者缺一不可、互相关联,但从国家宏观就业指导方针、道德原则的稳定性、持久性以及普遍性的角度看,应该坚持“公正”重于“关护”。     

MUTUAL FUND MORTALITY, 12B‐1 FEES,AND THE NET EXPENSE RATIO

The Securities and Exchange Commission is currently reviewing Rule 12b‐1, which governs how fund advisors may pay for the distribution of fund shares. We provide evidence that even after adjusting for economies of scale, funds with 12b‐1 fees have higher expense ratios net of the 12b‐1 fees than do funds without such fees. This finding suggests that 12b‐1 fees are more than just a deadweight cost. We also demonstrate that 12b‐1 fees are highest for funds that ultimately fail, that the proportion of funds with 12b‐1 fees is increasing over time, and that the level of those fees is also increasing over time.

赤道原则-国际金融公司政策的延伸

赤道原则是国际项目融资的环境与社会的最低行业标准。它的制订与执行由国际金融公司主导,它的核心内容基本上援引了国际金融公司的政策和指南,国际金融公司环境与社会政策的评审结果关乎着赤道原则的命运。国际金融公司也帮助赤道银行培训赤道原则专家,国际金融公司的政策与实践直接影响赤道原则的性质。它把自己定位为开发性金融规则的提倡者,是由于现实因素的推动,客观上提高了银行的公众形象,也提高了国际金融公司自身的形象。     

The determinants of rural and urban household poverty in the North West province of South Africa

Based on standard poverty measures, the extent of poverty in the North West province is on average worse than in South Africa. For instance, the poverty gap ratio for North West is twice that of the South African average, and the FGT index is three times as high. This article therefore aims to identify the determinants of rural and urban poverty in the North West province of South Africa. Using data gathered from a survey of 593 black households across the province, probit model estimates suggest that the major significant determinants of household poverty in both rural and urban areas are education and household size. A difference between rural and urban poverty is, first, that extra female adults in a rural household raise the probability of poverty. Secondly, having a migrant (out) worker as head of the household in rural areas lowers the probability of poverty, while this does not apply to urban households. A sensitivity analysis for the robustness of the results over a range of poverty lines reveals that the impact of education is much stronger for poorer households than for more wealthy households.     

Absence management and the issues of job retention and return to work

Strategies aimed at facilitating the job retention and return to work of sick and injured workers are currently the subject of growing attention. In this article the authors examine the nature and potential significance of such strategies to absence management and utilise interview findings to shed light on current employer policies and practices relating to the management of long‐term absences. They conclude that at the national level a large proportion of working days lost through sickness absence stem from relatively long spells of absence and that the adoption of a proactive approach to supporting the return to work of ill and injured workers can have beneficial consequences. However, they further conclude that few organisations appear to have comprehensive arrangements in place to handle cases of long‐term absence. A number of areas where present employer arrangements could usefully be reviewed are therefore identified.
