Internet professionals: job skills for an on-line age

The paper explores the increasing popularity of the Internet technology Singapore. It argues that the diffusion of Internet technology to South-East Asia would create new duties and responsibilities for human resource (HR) managers. One such duty is the identification of the skills which professional Internet staff would need to perform their work effectively in organizations. Using a triangulation research method, empirical study has identified the new professional Internet jobs which have emerged the IT industry in Singapore and the skills that professional Internet personnel require do their jobs effectively. Analysis of the findings indicates that professional Internet skills involve both technical and creative abilities and that, in explaining or defining professional Internet skills, it is necessary to use both the technical and the social conceptions of skill. This argument is based on the view that the creative skills include tacit skills so that a definition based solely on the technical conception of skill cannot capture the various dimensions of Internet skills. The implications of the research findings for human resource managers are raised.     

Is quality accreditation effective? Evidence from the childcare market

The ineffectiveness of a quality accreditation mechanism can be attributed to the inability of the accreditation status to provide consumers with information they do not already possess. I present a structural model of demand allowing consumers to infer quality from both accreditation status and firm reputation. I then estimate this model to assess the effectiveness and the impact of the national accreditation system for childcare centers on consumer welfare. My results suggest that disregarding the endogeneity of firms' accreditation choices significantly underestimates the effectiveness of the accreditation system. However, on average consumers do not gain much information beyond what they have inferred from a firm's reputation. The estimates of structural parameters are then used to quantify the value of this information to consumers.     

Bargaining frictions, labor income taxation, and economic performance

This paper is an attempt to explain differences in economic performance between a subset of OECD countries. We classify countries in terms of their degree of rigidity in the labor market, and use a matching model with labor/leisure choice, bargaining frictions, and labor income taxation to capture these rigidity differences. Added flexibility improves economic performance in different ways depending on whether income taxation is high or low. Feeding income taxation rates estimated from the countries at hand, we find that the model is able to replicate the observed rigidity levels. The model is also shown to reproduce well cross-country differences in non-employment population ratios and the share of part-time jobs. In the absence of rigidity differences, taxation shows little promise to replicate cross-country differences, as it has insufficient quantitative effects on production and productivity. However, the interaction of rigidity and income taxation is crucial in explaining the empirical patterns of the non-employment rate and of the share of part-time jobs.     

The bullwhip effect on inventory: a perspective on information quality

In recent years, there has been a vast increase in the quantity of information shared across supply chain. We investigate how the timeliness and accuracy of information quality affect the value of information sharing. We use the inventory bullwhip effect (BWE) to measure the value of information sharing in a two-level supply chain consisting of one retailer and one manufacturer. The retailer faces a price-sensitive demand and the price is an AR (1) process. Our study shows if customer demand and retailer’s immediate order are delayed, using retailer’s historical order quantity to forecast can decrease manufacturer’s BWE. If information errors happen, during delivery and utilization, information sharing is not always valuable for the manufacturer. Sometimes, no information sharing can decrease much more of BWE. If information errors occur when the retailer collects demand information, value of information sharing is more significant than when there are no information errors.     

Jobs with different wage determination mechanisms, social efficiency and unemployment

The purpose of this paper is to construct a theoretical framework for the labor market, which is composed of a variety of jobs with different wage determination mechanisms. We identify an equilibrium in which some firms post a wage and others bargain with workers. This paper shows that the proportion of firms adopting wage bargaining in a decentralized equilibrium is below the socially optimal level. We identify policies to increase this proportion and to improve social efficiency. Furthermore, we examine the impact of those policies on unemployment. The results of this study will determine the direction of employment policy on the labor market with various employment styles.     

论信息经济发展与信息化水平测算方法

信息经济是以现代信息技术为手段,以信息资源为劳动对象而形成的以信息产业为主导产业的经济。判定一个国家或一个地区是否进入信息经济社会,主要应遵循产业结构演进的规律性、信息产业产值的大小及其年增长率高低等三条标准。由于现代信息技术的快速发展已引起了社会信息化测算对象发生了极大变化,所以必须根据这种变化研究社会信息水平测算的新方法,以便定量的测算社会信息化状态。     

Information asymmetry,mutual funds and earnings management: Evidence from China

This paper investigates how information asymmetry and mutual fund ownership affect listed companies’ earnings management. We show that (1) reducing information asymmetry improves firms’ earnings management behavior; (2) relative to short-term mutual funds, long-term mutual funds promote earnings quality by adopting a monitoring role; and (3) by dividing firms into high/low information asymmetry groups, we find that the information environment significantly increases the effect of long-term mutual funds on firms’ earnings management. In this paper, we provide new evidence for the role that institutional investors play in a typical emerging capital market. Our results have clear policy implications: to increase earnings quality, it is essential to improve information transparency and develop long-term institutional investors.     

A study of the internal control structure for electronic data interchange systems using the analytic hierarchy process

Electronic data interchange (EDI) systems involve the direct exchange of structured business data between trading partner computer systems. A reliable internal control structure is the primary means of providing assurance of information integrity in EDI systems. This paper reports the results of a study that examined information system (IS) managers' and computerised information system (CIS) auditors' judgements of the relative importance of elements of the internal control structure for EDI systems, using the analytic hierarchy process (AHP). It then assessed the degree of consensus in their judgements. Generally consensus was found to be high. However, the areas where there was lack of consensus may indicate potential areas of control weakness in EDI systems.     

The market microstructure approach to foreign exchange: Looking back and looking forward

Research on foreign exchange market microstructure stresses the importance of order flow, heterogeneity among agents, and private information as crucial determinants of short-run exchange rate dynamics. Microstructure researchers have produced empirically-driven models that fit the data surprisingly well. But FX markets are evolving rapidly in response to new electronic trading technologies. Transparency has risen, trading costs have tumbled, and transaction speed has accelerated as new players have entered the market and existing players have modified their behavior. These changes will have profound effects on exchange rate dynamics. Looking forward, we highlight fundamental yet unanswered questions on the nature of private information, the impact on market liquidity, and the changing process of price discovery. We also outline potential microstructure explanations for long-standing exchange rate puzzles.
