Bilateral political relations and sovereign wealth fund investment

We examine the role of bilateral political relations in sovereign wealth fund (SWF) investment decisions. Our empirical results suggest that political relations play a role in SWF decision making. Contrary to predictions based on the FDI and political relations literature, we find that relative to nations in which they do not invest, SWFs prefer to invest in nations with which they have weaker political relations. Using a two-stage Cragg model, we find that political relations are an important factor in where SWFs invest but matter less in determining how much to invest. Inconsistent with the FDI and political relations literature, these results suggest that SWFs behave differently than rational investors who maximize return while minimizing risk. Consistent with the trade and political relations literature, we find that SWF investment has a positive (negative) impact for relatively closed (open) countries. Our results suggest that SWFs use—at least partially—non-financial motives in investment decisions.     

Experience, information asymmetry, and rational forecast bias

This study examines whether it is ever rational for analysts to post biased estimates and how information asymmetry and analyst experience factor into the decision. Using a construct where analysts wish to minimize their forecasting error, we model forecasted earnings when analysts combine private information with consensus estimates to determine the optimal forecast bias, i.e., the deviation from the consensus. We show that the analyst??s rational bias increases with information asymmetry, but is concavely related with experience. Novice analysts post estimates similar to the consensus but as they become more experienced and develop private information channels, their estimates become biased and deviated from the consensus. Highly seasoned analysts, who have superior analytical skills and valuable relationships, need not post biased forecasts.     

The Volatility of Foreign Portfolio Investment and the Access to Finance of Small Listed Firms

This paper examines the impact of foreign portfolio investment (FPI) volatility on the access to capital of small listed firms. The volatility of FPI is significantly associated with decreased access to finance for small listed firms only in years when nations are considered less “creditworthy.” Even in these times, however, the benefits of FPI are not completely depleted. These results underscore the significance of both a good financial system that minimizes capital flow volatility and national creditworthiness in inspiring confidence in foreign investors.     

Spin‐outs: knowledge diffusion through employee mobility

In many industries, one important method of diffusion is through employee mobility: many of the entering firms are started by employees from incumbent firms using some of their former employer's technological know‐how. This article explores the effect of incorporating this mechanism in a general industry framework by allowing employees to imitate their employers' know‐how. The equilibrium is Pareto optimal because the employees “pay” for the possibility of learning their employers' know‐how. The model's implications are consistent with data from the rigid disk drive industry. These implications concern the effects of know‐how on firm formation and survival.     

The impact of competition on the operations of foreign banks in Australia in the post-deregulation period

In 1985, Australia removed its long-standing embargo on the entry of foreign banks. The Australian market therefore provides an opportunity to study the factors influencing multinational bank expansion in a new host country. This paper tests a model of the size of multinational banking operations in Australia in the post-embargo period. One major finding is that a push for market share in a highly competitive environment led to risky lending practices in the global boom-bust economic climate of the late 1980s, which adversely affected the foreign banks’ performance. Another is that competition from home country banks had a significantly negative effect on foreign banks’ asset volumes.     

Corroborating social media echelon in cancer research

Worldwide medical facilities differ, and for this reason, the causes of death can vary. Cancer is considered the second leading cause of death after heart disease worldwide, and the same causes of death are observed in the United States (US). Therefore, the purposes of this study are to explore worldwide research levels in the field of cancer and the social collaboration of researchers and institutions in this field. This article examines the structural patterns of international co-authors and co-institutions in science citation index papers in cancer research. The study uses measures from the social network analysis method, including degree centrality, betweenness centrality, eigenvector centrality, and effectiveness, to investigate the effects of social networks in the area of cancer research. Empirical analysis results identify the US is the most central country, followed by Germany, Italy, France, and China, in terms of co-authored networks in this research field. Institutional analysis results indicate that the University of Milan is at the top in terms of degree centrality. The Gustave Roussy Cancer Campus in France and German University of Düsseldorf occupy the second and fourth positions, respectively. The University of California in Los Angeles and Harvard University, both in the US, are at third and fifth positions, respectively.     

Return Performance Surrounding Reverse Stock Splits: Can Investors Profit?

We examine the long-run return performance of over 1,600 firms with reverse stock splits. These stocks record statistically significant negative abnormal returns over the three-year period following the month of the reverse split. The sample firms experience poor operating performances over the four years that include and follow the year of the reverse split, which suggests informational inefficiencies. Because these stocks have unique financial characteristics, we also show that they would be very difficult to sell short. Thus, arbitrageurs would be restricted in their ability to earn abnormal profits, even if they correctly anticipated a price decline.     

Internal governance mechanisms and firm performance in China

Corporate governance issues arising from concentrated ownership structure in emerging economies have received growing attention. Adopting a principal–principal perspective, this paper employs structural equation modeling to evaluate the independent and interdependent effects of internal governance mechanisms in enhancing firms’ value in China. Based on a 3-year dataset covering 304 publicly listed companies over 2003–2005, our findings suggest that ownership concentration has the most significant governance effect and has impacted negatively on firm performance. Furthermore, the governance role of the board of directors and supervisory boards is found to have been hindered by ownership concentration, rendering them unable to improve firm performance at present.     

Evidence of short-term household change in South Africa from the National Income Dynamics Study

We use longitudinal data from the National Income Dynamics Study to document the extent of recent short-term residential and household compositional change in South Africa. We analyse the demographic correlates of these transitions, including population group, age, urban/rural status, and income. We examine educational and labour-market transitions among movers and the prevalence of the four major types of compositional change – births, addition of joiners, deaths, and loss of leavers. We find that short-term household change is prevalent in South Africa. During a two-year period from 2008 to 2010, 10.5% of South Africans moved residence and 61.3% experienced change in household composition. We find that moving is more common among blacks and whites, very young children, young adults, urban individuals, and those with higher incomes. Among non-movers, compositional change is more likely for blacks and coloureds, young adults and children, females, urban individuals, and individuals with lower incomes.
