(In)determinacy, increasing returns, and the optimality of the Friedman rule in an endogenously growing open economy

This paper sets up a monetary endogenous growth model with Benhabib–Farmer production externalities for an open economy, and then uses it to investigate the possibility of indeterminacy. Moreover, the paper examines how the monetary authorities will set its optimal anchor of the money growth rate from the viewpoint of welfare maximization. Several main findings emerge from the analysis. First, when investment does not involve adjustment costs, the monetary equilibrium is locally determinate regardless of the strength of the labor externality and the extent of world capital market imperfections. Second, in the presence of investment adjustment costs, the monetary equilibrium may exhibit indeterminacy when the aggregate increasing returns-to-scale in production is sufficiently strong. Third, in the presence of world capital market imperfections, the Friedman rule of a zero nominal interest rate fails to be optimal. Fourth, in the face of perfect world capital markets, the optimal nominal money growth rate is maintained at the rate that is conformable to the Friedman rule, regardless of whether investment involves adjustment costs or not.     

Earnings forecast disclosure regulation and earnings management: evidence from Taiwan IPO firms

This study examines whether the Taiwanese regulation requiring disclosure of earnings forecasts in the IPOs resulted in disclosure of more optimistic earnings forecasts and whether the forecast error was reduced more by manipulating the reported earnings rather than revising the earnings forecasts to meet the forecast error threshold. The study is based on 759 forecasts issued by the Taiwanese IPO firms from 1994 to 2001, i.e. 8-year period after the regulation was modified to increase the forecast error threshold to 20%. The findings show that the disclosure regulation resulted in more optimistic forecasts than conservative forecasts, especially for firms expecting better performance in the forecast year compared to the previous year. Firms disclosing optimistic earnings forecasts engaged more in manipulation of reported earnings than revision of forecasts to meet the forecast error threshold. These findings thus suggest that the disclosure regulation resulted in earnings manipulation, which reduced the quality of reported earnings. We received valuable comments at the 2003 American Accounting Association and 2004 Euorpean Accounting Association annual meetings. We also thank the participants at the research seminars at Rutgers University, City University of Hong Kong, and Pace University, for their insightful comments. Picheng Lee especially thanks Pace University for 2003 summer research grant.     

Exploring Factors Influencing the Use of Enterprise Social Networks in Multinational Professional Service Firms

ABSTRACT

Organizations are increasingly implementing enterprise social networks (ESNs) for improved communication and collaboration, as well as enhanced knowledge sharing and innovation among employees. However, the paradoxical relationship between ESN implementation and the promised benefits has been attributed to employees’ underutilization. Our research focuses on factors influencing employees’ decision to use ESN in their work role and draws on case studies of two multinational professional service firms (PSFs) based in Australia. Qualitative data were collected during ten semi-structured interviews with employees from both organizations, to determine their perceptions of ESN usage and capture the factors that influence their use behavior. The findings illustrate that the likelihood of ESN use is significantly influenced by technological, organizational, social and individual factors. A successful ESN use within an organization involves the nexus between these four factors and recommendations are made, as guidelines for organizational actors about how ESNs usage can be increased.     

Testing the validity of the monetary model for ASEAN with structural break

This study examines the validity of the long run structural relations underlying the monetary exchange rate model for Malaysia, Singapore, The Philippines and Thailand. Take into consideration the possibility of structural change, we examined the models using recent developed techniques of testing unit root and cointegration with a structural break. Our findings of three cointegrating relations among the variables in the system were further identified by testing theoretical restrictions on the cointegrating equations. The long run relationships were able to be interpreted according to the theory, hence, support the long run validity of the monetary exchange rate model.     

Multiphase Assessment of Project Risk Interdependencies: Evidence from a University ISD Project in Taiwan

Project risks evolve dynamically, so variations in risk influences during the life cycle of an information system development project require analyses to devise risk management strategies cost effectively and at the appropriate stages. This study extends the Decision Making Trial and Evaluation Laboratory technique, using network theory, to assess the risk interdependencies for distinct project phases. A multiphase observation of a university information system development project in Taiwan provides a more in‐depth understanding of the key risk factors. To enhance risk assessments, this study proposes integrating an interdependency indicator with risk exposure measures.     

Relationships among project manager’s leadership style, team interaction and project performance in the Taiwanese server industry

The purpose of this study was to investigate the relationships of the project manager’s leadership style with team interaction, and their impact on project performance. The second objective was to determine whether the effect of leadership style on project performance may be mediated by team interaction. To address the primary aims, a questionnaire-based survey was used to measure the project manager’s leadership style, team communication and collaboration, and overall performance of research and development (R&D) projects in the Taiwanese server industry. The analyses suggest that transformational leadership may be positively related to team communication and collaboration. Additionally, levels of team communication and collaboration are positively associated with projects’ levels of performance. The results also indicate that team communication and collaboration may serve as mediators between transformational leadership and project performance.     

Factors affecting investors’ intention to purchase gold and silver bullion: evidence from Malaysia

Gold and silver prices have surged since the 1980s, and they have been used as a store of value for fear of a financial meltdown. However, gold and silver in the form of bullion are still not so popular compared with other gold and silver products (jewellery) and other financial instruments in Malaysia. Limited study has actually verified the factors that affect the investors’ intention to purchase bullion. Thus, this study explores factors affecting investors’ behaviour and their intention to purchase bullion based on the Theory of Planned Behaviour. This study also examines the moderating effect of scepticism between investors’ behaviour and their intention to purchase bullion. A total of 208 sets of data collected in a self-administered online structured survey was analysed using PLS-SEM. This study finds that investors’ behavioural belief and control belief significantly and positively affect their respective attitude towards behaviour and perceived behavioural control and, thus, intention to purchase bullion. Results are found insignificant for normative belief, normative attitude and intention to purchase bullion and the moderating effect of scepticism in affecting investors’ intention to purchase bullion. The findings of this study hope to provide insight and deeper understanding to bullion traders and financial advisors in improving their marketing strategies in growing interest in the bullion market.

     

Real exchange rate shocks and new product margins in the export market

This study examines the impact of industry real exchange rate (RER) shocks on plant and product exports using a comprehensive dataset for South Korea from 1990 to 1996. We find that RER changes have heterogeneous effects on real exports of existing exporters in terms of their productivity, and the positive RER depreciation effect on exports is more pronounced for less productive plants. At a product level, we find new evidence that a weak home currency prompts exporters to introduce new products to the export market, especially more remarkable for low-productivity plants. In contrast, a strong home currency leads to product exit with less significance.     

Employees striving for innovation in social enterprises: The roles of social mission and commitment-based human resource management

Social enterprises, promising organizations for solving societal problems with innovative approaches, rely upon their members’ active roles for workplace innovation. However, we still have a limited understanding about how social enterprises can foster employees’ endeavors for innovation. By focusing on employee learning and innovative behavior, we investigate the influences of perceived social mission, value congruence, and human resource management (HRM) practices in social enterprises. We conducted two complementary studies to answer our research questions. In Study 1, with a survey of 369 employees from 68 social enterprises, we examined a multilevel moderated mediation model with firm-level and individual-level data. We found that perceived social mission promoted learning and innovative behavior by increasing value congruence, and that commitment-based HRM practices enhanced the overall process from mission to employee efforts for innovation. In Study 2, with 300 daily surveys from 60 employees participating in an experience sampling study, we found that those with high-value congruence showed a significantly more stable pattern with less variance in innovative behavior than in learning behavior. Our study adds novel implications to the underdeveloped literature on employee innovation and HRM in social enterprises by uncovering the positive effects of social mission and value facets for boosting learning and innovative behaviors. Our research also suggests that social enterprises should benefit from pursuing and emphasizing the social mission and commitment-based HRM bundle together, which will promote the prosperity and well-being of business and society.
