On the optimal mix of corporate hedging instruments: Linear versus nonlinear derivatives

We examine how corporations should choose their optimal mix of linear and nonlinear derivatives. We present a model in which a firm facing both quantity (output) and price (market) risk maximizes its expected profits when subjected to financial distress costs. The optimal hedging position generally is comprised of linear contracts, but as the levels of quantity and price‐risk increase, the use of linear contracts will decline due to the risks associated with overhedging. At the same time, a substitution effect occurs toward the use of nonlinear contracts. The degree of substitution will depend on the correlation between output levels and prices. Our model also allows us to provide insight into the relation between a firm's derivatives usage and its transaction‐cost structure. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:217–239, 2003     

The effect of trust on value on travel websites: enhancing well-being and word-of-mouth among the elderly

Despite older adults’ potential for engagement in e-commerce, there is limited understanding of what makes them achieve well-being while using a travel website. In addressing this research gap relating to older adults’ travel website experiences, this study highlights the important role of trust generating value in the context of travel websites. Specifically, this paper examines the relationships between trust, functional and hedonic values, well-being, and word-of-mouth (WOM). We analyzed 300 older adults in the United States (US) who used travel websites and purchased package tours, employing the structural equation modeling technique. The results show that trust significantly influences both functional and hedonic values, both of which result in well-being. Interestingly, hedonic value has a stronger effect on well-being than functional value, leading to WOM.     

Determining factors for the adoption of e-business: the case of SMEs in Korea

This study investigates the determining factors of the successful adoption of e-business by small and medium enterprises (SMEs) in Korea using survey data. After the major determining factors were identified from the innovation adoption literature and were extracted by applying the principal component analysis to the survey data and by adding the country-specific characteristics of Korea, we conducted empirical analyses to determine the critical success factors for the adoption of e-business by Korean firms. The empirical results which are based on t-tests of the differences between adopters and non-adopters, the linear probability model, and the logit model, all suggest that the important determinants of the successful adoption of e-business by SMEs in Korea are: the CEO's knowledge of information technology (IT)/e-business, relative advantages and benefits from implementing e-business, governmental support, globalization strategy and the North Korean factor. Business size, the cost of e-business adoption and competitive pressure of the industry do not seem to play an important role in the adoption of e-business by Korean SMEs. The policy implications of this study on promoting e-business adoption by SMEs in emerging economies, such as Korea, are also discussed.     

How foreign direct investment promote institutional quality: Evidence from Vietnam

Using a unique dataset from a provincial competitiveness survey and the rising foreign direct investment (FDI) from joining the World Trade Organization (WTO), I find that variations in economic institutions across the provinces of Vietnam are associated with the flow of foreign investment. To overcome endogeneity problems, I use the minimum distance from each province to a main economic centre as an instrument for foreign investment inflows. The instrumental variable approach shows that the direction of influence is from greater foreign investment to better institutions. These results hold after controlling for various additional covariates, and are also robust to various alternative measures of institutions. I also find that foreign direct investment has greater short-term impacts on institutional quality in the northern provinces.     

Financial distress and bankruptcy prediction: An appropriate model for listed firms in Vietnam

This paper aims to develop a comprehensive model, the first of its kind in Vietnam, for the purpose of predicting financial distress and bankruptcy at Vietnamese listed firms. The period 2003–2016 is used to study the likelihood of financial distress in different scenarios. Various factors are utilized, including (1) accounting factors in the emerging market score model; (2) market factors in the distance-to-default model; and (3) macroeconomic indicators. The area under the receiver operating characteristics (AUC) curve is used to compare the usefulness of various models that predict financial distress and bankruptcy. Empirical findings from this study show that accounting and market factors, together with macroeconomic fundamental factors, both affect financial distress when they are considered in isolation. However, in a comprehensive model, the effects from accounting factors appear to be more significant than those from market-based factors. The default prediction model, which includes accounting factors with macroeconomic indicators, appears to perform much better than the model comprising market-based factors with macroeconomic fundamentals.     

中国与越南增值税制比较

中越两国都是在建设社会主义市场经济,实现经济体制转轨的大背景下引进增值税这一税种的,现在都已成为各自的第一大税种.同时两国在增值税纳税人、征税对象、税率、增值税类型、计算方法、进项税额的确定等方面都存在诸多差异.从比较中可以得到一些有益的思考,对于推动我国的增值税改革有着借鉴意义.     

An alternative approach to evaluating the agreement between financial markets

This research investigates that the price relationship between a stock index and its associated nearby futures markets can be explained by the cost-of-carry model using the concordance correlation (CC) coefficient in the US financial markets. The main purpose of this research is to confirm that the CC coefficient is an appropriate methodology to determine ex post arbitrage opportunities and to maximize ex ante arbitrage profits through the analysis of the price relationship derived from the cost-of-carry model. To increase the robustness of the results and to enable us to generalize our conclusions, this analysis is carried out in consideration of external uncertainty, including the marking-to-market procedure of futures contracts and the transaction cost on the stock index and its futures markets, under several assumptions related to the conditions of transactions. Examining transaction price data on the S&P 500 stock index and its futures markets shows that the CC coefficient gives a good result for ex ante arbitrage profits and is appropriate for analyzing the relationship between the observed stock index futures market price and its theoretical price derived from the cost-of-carry model.     

Exploring the Attitudes of Bottled Wine Distributors Toward Wine Producers in the Portuguese Wine Sector

The wine sector has unique features that have not been deeply studied. This study aims to explore the attitudes of bottled wine distributors toward wine producers in the Portuguese wine sector. Eleven interviews (about 60 min each) were carried out with all major wine distributor managers. The transcribed interviews were analyzed using qualitative software. Content analysis shows that distributors develop six main attitudes toward producers: (a) Long-term Relationship, (b) Cooperation, (c) Interdependence, (d) Product Quality, (e) Trust, and (f) Brand Image. Findings may help managers of the wine sector and promote favorable relationships with the distributing customers.     

The Role of NSOs in Assuring National Prosperity: A Case Study of Korea

As changes in the socio-economic environment become more rapid, so the role of statistics in society becomes more important. At the same time, the role of a national statistical office (hereafter NSO) as a provider of official statistics attracts increasing interest because the function of an NSO in a country assuredly depends on changes in the economic and social surroundings in pursuit of national prosperity.
In this paper, the strong relationship between the social and economic development of a country and the development of a national statistical office will be explicated using the example of Korea, which has experienced dynamic take-off in both economic and social sectors during the last 40 years. The progress of the Korean NSO will be studied in three time periods by looking at the socio-economic changes in each period, and how the NSO responded. In addition, as the Global Age emerged in the late 1990s, the Korean NSO started to encounter new demands at a time of limited resources and a worsening statistical environment. In light of this, several current issues and corresponding strategies for NSOs will be suggested.     

Inflation and Structural Change in 50 Developing Countries

This study provides evidence on whether the inflation rate is stationary or nonstationary using quarterly inflation rate data from 50 developing countries. As Johansen [Johansen, Soren. “Testing Weak Exogeneity and Order of Cointegration in UK Money Demand Data,” Journal of Policy Modeling, 14, 3, June 1992, pp. 313–334] put it, “some time series such as the log of prices (P), have the property that even the inflation rate ΔP is nonstationary, whereas the second difference Δ²P is stationarity.” Results from fractional integration analyses provide evidence of long memory and confirm that the nonstationarity threshold of d³0.5 is satisfied in the majority of the cases. Results from recursive analyses indicate that, despite the finding that structural changes influence the behavior of the estimated integration parameters, evidence of long memory and nonstationarity can be found in each subsample as well as the full sample data.
