Stock exchange mergers and market efficiency

The aim of this article is to examine the impact of stock exchange mergers on the degree of informational efficiency. For this purpose, we apply the generalized spectral shape test for the martingale difference hypothesis to the stock returns before and after the 31 domestic and cross-border mergers completed from 1997 to 2011. The test is conducted with moving subsample windows, allowing us to detect the periods of (in)efficiency, and thus to conduct a comparative analysis for pre-merger and post-merger periods. We find that higher levels of efficiency are less frequent than lower levels of efficiency after a stock exchange merger. We also find that the impact on the level of efficiency depends on a range of merger characteristics such as the level of development, size, geographical diversification and industrial diversification of stock exchange.     

Who shapes network neutrality policy debate? An examination of information subsidizers in the mainstream media and at Congressional and FCC hearings

Recognizing policy-making process as a communicative process, this study examines who has subsidized information relating to the net neutrality policy debate. Empirical data has been collected from net neutrality stories published in four national newspapers, as well as from hearings by Congress and the Federal Communications Commission (FCC), during the period of February 2004 through January 2009. Study findings reveal that corporate interests have played a significant role in subsidizing information on net neutrality, both to the public through the mainstream media and to legislators through Congressional hearings. Furthermore, study results show that experts played a larger role in defining net neutrality through the mainstream media and FCC hearings than they did through Congressional hearings. Finally, the role of advocacy group representatives was more apparent at Congressional hearings than via the other two available information channels.     

A marginal analysis guided technology evaluation and selection

Making decisions on strategic investments, such as early stage manufacturing technology (MT), is a complicated task. Early stage technologies are usually costly, and surrounded by uncertainty. The potential benefits are often hard to quantify prior to implementation. Thus, how could managers make good decisions in a high-risk, technically complex business when the information they need to make those decisions comes largely from the project champions who are competing against one another for resources? Traditionally, in this problem domain, decisions are made based upon gut-feeling and past experience, sometimes with the support of some multi-criteria decision-support tools. The criteria evaluation process is very subjective and relies heavily on managers’ experience, knowledge, as well as intuition. Thus, the evaluation approach is often not effectively carried out as there is lack of visibility and traceability in the decision making process. The impact of this scenario is that managers are not confident that resources are being optimised and applied to a mixed portfolio of projects to maximise benefits. This paper proposes a marginal analysis directed branch and bound approach for evaluating and selecting early stage manufacturing technology (MT) projects. A case study is used to demonstrate the application of the proposed approach. Implications of the proposed approach to practitioners and academia are discussed and future research outlined.     

Statistical manipulability of social choice functions

We consider the proportion of profiles at which an anonymous neutral social choice function cannot be manipulated to any coalition's advantage. We fix the number of alternatives and consider the limit as the number of individuals goes to infinity, and assume that the limit of the fraction of all profiles in the domain is 1. We show that there is a continuous function on “profile vectors’ which gives the maximum probability of strategy-proofness, and that this is strictly between 0 and 1 for three alternatives. We also analyze a number of common social choice functions along these lines.     

Doing business in Poland: What U.S. managers need to know

Poland has been and continues to be the leader of the transition economies of Eastern Europe. This study provides an in‐depth look at the ongoing economic, legal, and administrative policies of the Polish government in laying the ground‐work for a free‐market society. With the smaller business in mind, we first examine how the government of Poland moved decisively to lay the cornerstone for a private‐sector economy. Next, we demonstrate how Poland redirected its political and legal processes for long‐term global business. Finally, we describe what the U.S. government is doing to help Poland become a better trading partner and what this means to interested American firms. While there are many deep‐seated positive changes throughout Poland as it becomes a more significant global business player, there also are many challenges that must be understood by interested U.S. businesses if their investments in Poland are to be successful. © 2004 Wiley Periodicals, Inc.     

Value Congruence Awareness: Part 2. DNA Testing Sheds Light on Functionalism

Part 1 of this exploratory study demonstrated that for terminal, instrumental, and work values, supervisors could only accurately assess the extent to which their terminal values are congruent with their employees, whereas, employees could only accurately describe degrees of alignment with their supervisors' work values. Thus, supervisors appear to possess conscious awareness of the terminal values held by their employees and employees similarly possess conscious awareness of their supervisors' work values. Part 2 of the study examined what each of these two parties might do with their conscious knowledge concerning value congruence with the other member. Supervisor ratings and employee self-ratings concerning employee job performance, citizenship, climate fit, working relationship (LMX), and other issues, were correlated with supervisor terminal value congruence estimates and employee work value congruence estimates respectively. For supervisors, only one significant finding was noted, indicating a positive relationship between the supervisors' awareness of terminal value congruence with the employee and the supervisors' estimate of the employee's potential for future promotion. For employees, seven hypotheses received support demonstrating relationships between the employees' 0awareness of supervisor/employee work value congruence and self-ratings of work behaviours, citizenship behaviours, volunteerism behaviours, work climate behaviours, work climate attitudes, work climate organizational-wide attitudes, and the supervisor/employee working relationship. Implications for management and future research are discussed.     

Do Capital Inflows Matter to Asset Prices? The Case of Korea*

In the present paper, we investigate whether capital flows induce domestic asset price hikes in the case of Korea. This issue is relevant for crisis‐hit economies trying to prevent a boom–bust cycle as well as in the formulation of macroeconomic policy objectives in emerging market economies. Korea has recently experienced large capital inflows, in particular a surge in portfolio inflows. Furthermore, asset prices, including stock prices, land prices and nominal and real exchange rates, have also appreciated. The empirical results, obtained using a vector autoregression model, suggest that capital inflow shocks have caused stock prices but not land prices to increase. The effects on the nominal and real exchange rates have been limited, which relates to the accumulation of foreign exchange reserves.     

Specialization,diversification, and productivity: a panel data analysis of rice farms in Korea

This article examines the microeconomics of productivity associated with specialization/diversification in production activities, with an application to Korean rice farms. Korean rice farms tend to be very small and highly specialized. Our analysis examines the productivity effects associated with both farm size and farm specialization/diversification in Korean agriculture. Relying on farm‐level panel data, the analysis studies farm productivity in a multi‐input multi‐output context, accounting not only for changes in inputs and technical change in rice production, but also for the role of diversification in the production of other crops in current and previous periods. We find positive but small productivity gains from farm diversification. These gains come mostly from complementarity effects across farm outputs, with minimal effect of scale economies. The positive complementarity effects work against nonconvexity effects, which provide strong productivity incentives for rice farms to specialize.     

Vertical Specialization and Trade Growth in Northeast Asia

As the global economy has become further integrated, the international production chain has become more sophisticated, with diversified stages of production located in different countries. Economic theorists have argued that the fragmentation of the global production chain is partly attributable to the high growth in international trade over the past several decades. In this study, we examine vertical specialization in China, Japan and Korea, and its contribution to these nations' trade. Using a multilevel model, it is illustrated that vertical specialization has encouraged increases in trade among all three countries. In particular, China's outcome is remarkable considering how recently it became a member of the WTO.
