Simulating the Effects of Railroad Mergers

The purpose of this paper is to add to the empirical literature regarding merger simulation analysis by examining the effect of railroad mergers on railroad market power. This is done by measuring railroad profits and revenue/variable cost ratios corresponding to different degrees of intrarailroad competition for movements of Kansas export wheat to Houston, Texas. Two models are developed to achieve the objectives of the study. A network model of the wheat logistics system is used to identify the least cost transportation routes from the Kansas study area to the market at Houston. A profit improvement algorithm, which identifies Nash equilibrium prices, is developed to measure the amount by which railroads can profitably raise their prices above variable cost. The results of the study have implications for U.S. railroad merger policy. The paper indicates that railroad mergers do not necessarily increase railroad market power or make railroad shippers worse off. Instead, the study demonstrates that the impact of railroad mergers on shippers and railroads depends on factors that vary geographically, such as the degree of intrarailroad and intermodal competition in the area.     

What factors of early-stage innovative projects are likely to drive projects’ success? A longitudinal analysis of Korean entrepreneurial firms

Previous studies have identified the factors affecting successful technology commercialization as outcomes of R&D projects. However, most of them have used cross-sectional data, whereas there is a dearth of literature using longitudinal data analysis. Longitudinal analysis is essential for investigating the characteristics of early-stage innovative projects due to the inherent time lag between project evaluation and commercialization. Therefore, this study examines the early-stage project characteristics that can be used as meaningful evaluation criteria for predicting success, particularly in technology commercialization. We collected data on the ex-ante evaluation results and ex-post commercialization results of R&D projects pursued by entrepreneurial firms. We then conducted a logistic regression analysis and identified three market-related factors as significant in driving technology commercialization success in the early stages of technology development: market potential, commercialization plan, and market condition.     

On financial guarantee insurance under stochastic interest rates

We extend the financial guarantee insurance literature by modeling, under stochastic interest rates, private financial guarantees when the guarantor potentially defaults. By performing numerical simulations under plausible parameters values, we characterize the differential impact of the incorporation of stochasticity of interest rates on the valuation of both public and private guarantees.     

Food Security and Agricultural Protection in South Korea

South Korea has been pursuing food self-sufficiency using high tariffs and high administrative prices in key agricultural and food markets. Using a dual approach to trade and trade restrictiveness indices, we analyze the impact of these market distortions on welfare and trade volume. Then, we compute second-best distortions, which minimize the welfare cost of meeting observed levels of self-sufficiency and production. We rationalize these second-best distortions to what could be claimed as legitimate protection under a "food security" (FS) box in World Trade Organization (WTO) negotiations. FS-box protection is sensitive to changes in the definition and the extent of the FS objectives. We show that FS via production targets and reliance on imports would be more palatable to consumers and trade partners, while preserving income transfer to the farm sector.     

Option pricing: A general equilibrium approach

This article examines option valuation in a general equilibrium framework. We focus on the general equilibrium implications of price dynamics for option valuation. The general equilibrium considerations allow us to derive an alternative option valuation formula that is as simple as the Black and Scholes formula, and that exhibits different behavior with respect to the exercise price and time to expiration. They also help us clarify comparative-statics properties of option valuation formulas in general and of the Black and Scholes model in particular.     

Beyond absorptive capacity in open innovation process: the relationships between openness,capacities and firm performance

The literature has shown that open innovation (OI) can be a winning strategy in improving firm performance. However, in order to adopt and implement it, managers need to resolve practical problems, such as understanding the role played by OI capacities and openness on firm performance. In response to these needs, this study aims to investigate the hierarchical relationships between openness, OI capacities and performance using a structural equation model approach. This paper also attempts to compare the levels of openness between firms in different industries to discover similarities and differences in OI phenomena. The analysis of data obtained from a survey of Korean firms shows significant interrelations between openness, OI capacities and firm performance. Our results go further in developing understanding of the building blocks on which successful OI is built and particularly suggest that desorptive capacity which underpins the out-bound OI process, is in turn strongly supported by knowledge management capacity. It is hoped that the results of this study can enrich our understanding of the OI mechanism and provide managerial and policy implications.     

Editors’ introduction transitional economies: Progress and pitfalls

Many Asian countries are undergoing transition from centrally planned to market-oriented economies. The People's Republic of China (PRC) and Viet Nam have been going through this transition since the 1980s, while Mongolia and the former Soviet republics of Armenia, Azerbaijan, Georgia, Kazakhstan, Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan began their transition in the 1990s with the dissolution of the Soviet Union in 1991. On the other hand, Cambodia, the Lao People's Democratic Republic, and Myanmar, while they have begun reforms, are still in the early stages of transition. North Korea has probably made the least progress in this regard. This Special Issue on Transitional Economies aims to provide valuable insights for Asia's developing countries still in transition and to provide them with policy recommendations for avoiding the pitfalls of transition experienced in the 1990s.     

Interdisciplinarity in design education: understanding the undergraduate student experience

Interdisciplinarity is becoming a critical issue of concern for design schools across East Asia in their attempts to provide industry graduates with the skills and competences to make creative contributions in a global economy. As a result, East Asian higher education institutions are aggressively endeavouring to provide interdisciplinary undergraduate curriculum that combine traditional designerly skills with engineering knowledge and methods. The current study takes an interdisciplinary undergraduate course as case-study to examine how the pedagogic strategy of team teaching influences student learning experience. Two surveys of student learning were conducted for this research purpose. The first provided an indication of the holistic student learning experience, while the second explored the conditions of team and non-team teaching as influence upon learning experiences specifically. Results showed how students taught by a single instructor provided a more positive overall opinion of course quality and experienced significantly more encouragement to participate compared to team taught respondents. However, findings also indicated how team teaching significantly increased the students’ experience of a balanced contribution from different disciplinary perspectives and how the team teaching approach was significantly more effective in providing students with greater opportunities to understand the relevance of the different disciplines to the course subject. We conclude with a discussion of results in terms of the effective use of team teaching at undergraduate level as strategy for interdisciplinary learning experiences.
