Modeling and optimization of a container drayage problem with resource constraints

This paper investigates the problem faced by firms that transport containers by truck in an environment with resource constraints. The considered area is export-dominant. As a result, there are three types of container movements as inbound full, outbound full, and inbound empty movements. Both the time windows at the terminal and at the customers’ places and the operation times are considered. Empty containers are also regarded as separate transportation resources besides trucks. The total operating time including waiting time of all the trucks in operation is minimized. The problem is first formulated as a directed graph and then mathematically modeled based on the graph. It falls into a multiple traveling salesman problem with time windows (m-TSPTW) with resource constraints. An algorithm based on reactive tabu search (RTS) is developed to solve the problem. A number of randomly generated examples indicate that the algorithm can be applied to the real world.     

What attracts foreign direct investment into autocratic states? Regime time horizon and institutional design

States play a critical role in designing institutions to facilitate international business. We study the effect of autocratic states' time horizons on their attraction of foreign direct investment (FDI) through designing domestic and international institutions. We argue that autocrats with a long time horizon tend to build credible domestic commitment-institutions that attract foreign investors; however, they are also likely to affect the design of commitment carve-outs in international institutions, in particular bilateral investment treaties, thus weakening their institutional effect on foreign investment. We test these dual effects of regime time horizon on FDI inflow using data from 80 autocratic states over a 33-year period and find substantial support for our arguments.     

Distance education in the future: Exploring the application of distributed group support systems

Distributed Group Support Systems (DGSS) provide a means for several individuals to interact with one another from different geographic locations using telecommunications and Group Support Systems (GSS) technologies. As this technology emerges, new applications will be sought to utilize the tremendous capabilities for long distance interaction and communication. One potential application of DGSS is its use in the delivery of Distance Education. Distance Education (DE) involves the delivery of education (or training) from one site to one (or more) geographically dispersed sites. The capability of DGSS to add an additional communications channel, one by which all students could interact with one another at the same time, provides an exciting array of opportunities for the application of DGSS. This article explores ways in which DGSS could be utilized to improve the delivery of education and training to dispersed locations. Background information of GSS and DE are provided Results of a case, study in which a fiber optic cable network was used for delivering a DE class on Information Systems are briefly highlighted, along with suggestions for future research in this area.A previous version of this article appears in the Proceedings of the Twenty-Seventh Annual Hawaii International Conference on Systems Sciences, Volume IV, pp. 142–148.     

Dissecting Foreign Bank Lending Behavior During the 2008–2009 Crisis

This paper analyzes the lending behavior of foreign‐owned banks during the recent global crisis. Using bank‐level panel data for 51 countries, the paper explores the role of affiliate and parent financial characteristics, host location, as well as the impact of parent geographic origin and reach on foreign banks’ credit growth. Overall, the analysis finds robust evidence that foreign banks curtailed the growth of credit relative to other banks, independent of the host region in which they operate. Banks from the United States reduced loan growth less than other parent banks. Neither the global nor regional reach of parent banks influenced the lending growth of foreign affiliates. Parent capitalization and not parent funding explained the behavior of foreign bank credit growth during the global crisis. However, funding did affect the lending behavior of domestic and foreign banks in host countries, with those relying more heavily on deposits suffering a smaller decline in bank lending. Although not the focus of the paper, we also find that government‐owned banks played a countercyclical role in all regions.     

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.     

Investment strategies by foreign automobile firms in China: A comparative study of Volkswagen,Honda, and Hyundai

The paper uses rolling sample tests to investigate time-varying calendar effects in the Chinese stock market, based on the GARCH (1, 1)-GED model. The Friday effect existed with low volatility at the early stage, but it seems to have disappeared since 1997. The positive Tuesday effect began to appear then. There is a small-firm January effect with high volatility. The turn-of-the month effect has also disappeared in the Chinese stock market since 1997.     

The effect of buyer feedback scores on internet auction prices

One of the major roles of Internet intermediaries is to help build trust between buyers and sellers for efficient and safe transactions. The buyer feedback system started in online auctions as one of the trust‐building mechanisms on the Internet. As the buyer feedback system is becoming a standard trust‐building mechanism in other e‐commerce sites as well as in online auction, there is an increasing interest about the impact of the buyer feedback system. On the top of recent studies investigating the effects of buyer feedback scores on auction prices, we provide empirical validations using more sophisticated methods. In this study, we tested the relationship between buyer feedback scores and bidding prices using an empirical data set from a leading consumer‐to‐consumer (C2C) Internet auction site. Data analysis results show a strong empirical validation of previous studies. Negative feedback is a significant price discount factor in the final auction price on the C2C Internet auction market. The results also show that potential buyers are more sensitive to negative feedback when they are considering buying inherently risky products such as used or refurbished products.     

Users' intentions to employ a Point-Of-Sale system

This study proposes that task, technology, and individual characteristics affect the Point-Of-Sale (POS) utilization of employees in service industry, specifically in restaurants. The integrated technology acceptance model and task–technology fit (TTF) model is appropriate for explaining service employees' behavioral intentions to use POS. Data were obtained from 167 service employees. The hypothesized model resulted in a good fit, supporting all eight proposed hypotheses. The TTF construct was confirmed to be a mediator of task, technology, and individual characteristics affecting intention to use. Our integrated model is expected to help researchers and practitioners better understand why service employees choose POS for their tasks and, further, how the technology characteristics of POS and its fit-with-task characteristics in a service sector lead to service employee choices.     

Equilibrium unemployment as a discipline device when finding employment is costly

Abstract In this paper, we study a model that incorporates costly job search into an efficiency wage model. We show that the relationship between wages and detection rates is ambiguous in this framework. The model can generate a positive relationship, consistent with empirically reasonable values for unemployment rates, job finding rates, and employment duration.     

CEO Ownership and Discretionary Investments

Abstract:  This study investigates empirically the relationship between CEO ownership and discretionary investments such as R&D and capital expenditures. We assert that the under-investment problem is high for R&D-intensive projects, while the over-investment problem is high for capital expenditures because of differences in risk between the two types of investments. Building on the linkages between investments and investment-related agency problems, we hypothesize that the relationship between CEO ownership and investments depends on whether increasing ownership mitigates or exacerbates the under- or over-investment problem. We find a non-linear association between CEO stock ownership and R&D investments; R&D investments increase and then decline across increasing levels of ownership. Further, we find that R&D investments and CEO stock options are positively associated at high levels of option holdings. In contrast, capital expenditures do not vary with CEO ownership (stock or options). Finally, consistent with our underlying assumption, we find that the influence of R&D investments on future firm risk is significantly larger than that of capital expenditures. Our findings indicate that managerial risk aversion affects discretionary investments.
