Are expansions cost effective for stock exchanges? A global perspective

This paper investigates the existence and extent of economies of scale and scope among the stock exchanges. Evidence from 38 exchanges in 32 countries and 4 continents around the world for the years 1989–1998 portrays the existence of significant economies of scale and scope. The degree of such scale and scope however differs across size and regions. The largest exchanges show an increasing trend of cost effectiveness. The exchanges in North America and Europe report substantially higher economies of scale relative to the exchanges in the Asia-Pacific regions.     

Water flow risks and stakeholder impacts on the choice of a dam site

This study evaluates three alternative locations for building a fresh water dam in the Yeşilirmak Valley of North Cyprus. Each of the three sites has different investment costs, water storage capabilities and socio-political repercussions. These kinds of trade-offs have in recent years characterised much of the worldwide debate surrounding the construction of electricity and irrigation dams. Another issue raised in this paper is the appropriate treatment of the risk and variability associated with the availability of water to fill the dam through time. This paper demonstrates how an integrated financial-economic-stakeholder analysis can provide the inputs needed by decision-makers in such situations to make rational political and economic choices.     

The effects of two directions of conflict and facilitation on frontline employees’ job outcomes

This study investigated the effects of two directions of conflict and facilitation simultaneously on job performance, job satisfaction, and affective organisational commitment based on data obtained from frontline hotel employees in Northern Cyprus. As expected, family–work conflict dimished job performance, while family–work facilitation enhanced job performance. Contrary to our prediction, conflict between work and family domains intensified job performance. The results of the path analysis revealed that work–family facilitation increased job satisfaction, while family–work facilitation triggered affective organisational commitment. The findings pertaining to the relationships between job performance, job satisfaction, and affective organisational commitment were in the hypothesised directions. Also, the results of the confirmatory factor analysis demonstrated that the four-factor model that consisted of work–family conflict, family–work conflict, work–family facilitation, and family–work facilitation was superior compared with other models tested. Implications of the empirical findings and their future research directions are discussed in our study.     

An IT professional’s dilemma: be an entrepreneur or a consultant?

Using a simple model, this paper examines the behavior of an IT professional who faces the choice between becoming an entrepreneur or an employee. To our knowledge, this is the first formal study of the dilemma facing an IT professional. IT professionals are somewhat unique in that they embody enough labor input/intellectual property that even a single professional can deliver a viable product/service. An incentive contract is auctioned to attract the highest bid in return for partial ownership from venture capitalists. Failure to raise venture finance results in the professional seeking employment. Both venture finance and employment are uncertain. The comparative-static effects of changes in project size and VC competition are determined. We find that under certain conditions a larger project is associated with a cost-plus contract, while greater VC competition results in a fixed-price contract being offered. The agent’s effort is lower in a larger project, but non-negative under greater VC competition.     

Data mining in road crash analysis: the context of developing countries

The recent advancements in the field of data mining have made vast progress in extracting new information and hidden patterns from large datasets which are often overlooked by the traditional statistical approaches. These methods focus on searching for new and interesting hypothesis which were previously unobserved. Road safety researchers working with the crash data from developed world have seen encouraging success in obtaining new insight into crash mechanism through data mining. An attempt was made in this study to apply these advance methods and evaluate their performance in manifesting crash causes for Bangladesh. The study applies hierarchical clustering to identify hazardous clusters, random forest to find important variables explaining each of these clusters, and classification and regression trees to unveil their respective crash mechanisms for the road crash data of Bangladesh. The results identified several new interesting relationships and acknowledged issues related to quality of data.     

The US bankruptcy law and private equity financing: empirical evidence

The generous personal bankruptcy law in the United States is important to entrepreneurs because failed entrepreneurs can resort to this system to shelter part of their wealth against negative consequences of business failure. Fan and White (Journal of Law and Economics XLVI:543–567, 2003) documented that high bankruptcy exemptions provide incentives for entrepreneurs to start/own new businesses. The partial wealth insurance effect provided by the bankruptcy exemptions also has a significant and negative impact on the entrepreneurs’ access to bank credits (Berkowitz and White, The Rand Journal of Economics 35(1):69–84, 2004; Gropp Scholz and White, The Quarterly Journal of Economics 112(1):217-251, 1997). In this article, we investigate whether and to what extent the US bankruptcy law has any effect on venture capital (VC) investment. Making use of company level information, we document that the amount of venture financing received is negatively related to the bankruptcy exemption levels, and the number of rounds of financing as well as the number of VC funds involved is negatively associated with bankruptcy exemptions. Further, we report consistent evidences based on state level data with regard to the effects of the US personal bankruptcy law.

Russian Roulette at the Trade Table: A Specific Factors CGE Analysis of an Agri‐food Import Ban

In the summer of 2014 Russia imposed a ban on most agri‐food products from countries enforcing Ukraine‐related sanctions against Russia. We use a specific factors computable general equilibrium (CGE) model to simulate the short‐run impact of this retaliatory policy. The baseline is carefully designed to isolate the impacts of the ban on the European Union (EU), Russia itself and a selection of key trade partners. The modelling of the ban follows a novel approach, where it is treated as a loss of established trade preferences via reductions in consumer utility in the Armington import function. Not surprisingly, the results indicate that Russia bears the highest income loss (about €3.4 billion) while the EU recovers part of its lost trade through expansion of exports to other markets. An ex‐post comparison between simulation results and observed trade data reveals the model predictions to be broadly accurate, thereby validating the robustness of the modelling approach.     

An Experimental Analysis of Face to Face versus Computer Mediated Communication Channels

Experimental research on Group Decision Support Systems (GDSS) has generally focused on democratic groups whose members typically share the same objectives. In organizations, however, there are many situations where groups have a leader who has the power to override the group's recommendation, the objective of the leader may not be the same as the objective of each member, and not everyone may have the same information. This paper reports the results of an experiment in which the groups, having a designated leader, worked on a mixed-motive task. Within this context, we analyze group decision outcomes and processes for groups that use a face-to-face channel of cormnunication and those that utilize computer mediated communication. We compare performance of the leader and members with respect to an objective measure of performance, the efficient frontier. The results indicate that for this task groups using face-to-face channel outperform groups using computer mediated communication.     

Measuring Takeover Premiums in Cross-Border Mergers and Acquisitions: Insights from Turkey

We investigate whether the merger announcement dates provided in a popular mergers and acquisitions (M&A) database, SDC, serve as accurate event dates for estimating the wealth effects of mergers on target firms located in Turkey. We find that 74 percent of SDC’s merger announcement dates are preceded by merger-related events such as merger rumors, target firms’ search for potential acquirers, and early-stage merger negotiation announcements. Target cumulative abnormal return (CAR) estimates around these early dates are almost twice as large as the CAR estimates around SDC’s merger announcement dates. We argue that our findings have implications for the recently flourishing cross-border M&A literature.     

Value relevance of banks: global evidence

Using 28,785 observations of 813 banking institutions in 38 countries during the 1993–2004 period, this study investigates among others, the role of transparency, accounting standards, legal, financing, corporate, and banking environments at the country level and size, risk, and organization form at the bank-specific level affecting the extent of value relevance. The evidence indicates that at the macro-level, the extent of mandated accounting disclosure, differences in accounting measurement practices, and type of legal environment, were the most influencing factors affecting the extent of value relevance of earnings and book values. At the bank-level, the organizational form and risk had the most impact.
