Understanding Japanese tourists’ shopping preferences using the Decision Tree Analysis method

This study was designed to assess the factors affecting Japanese tourists’ shopping preference and intention to revisit Korea. The analytical method applied in this study was Decision Tree Analysis, which is under-utilized in tourism studies. A total of 300 questionnaires were collected on the basis of on-site survey method and used for data analysis. Among interesting findings, three groups including ‘respondents who were satisfied, accompanied, and spent US$50–300 on shopping’, ‘respondents who were satisfied, accompanied, and had a shopping expenditure of US$300–1000’ and ‘respondents who were satisfied, accompanied, and had a shopping expenditure of US$1000–5000,’ showed a high level of intention to return to Korea for the purpose of shopping. In addition, two groups ‘those who were interested in shopping in Korea, preferred a shopping mall as a shopping destination, and had an educational level of below high school’ and ‘those who were interested in shopping in Korea, preferred a shopping mall as a shopping destination, and had an educational level of a college graduate or above’ showed a higher level interest in merchandise than in shopping venue attractiveness.     

Associated consistency and equal allocation of nonseparable costs

Summary. We modified the definition of associated game with respect to Hamiache (2001) to characterize the equal allocation of nonseparable costs (EANS) by means of Pareto Optimality(PO), Translation Covariance (TC), Symmetry (SYM), Associated Consistency(AC) and Continuity(CONT).Received: 8 April 2004, Revised: 9 May 2005, JEL Classification Numbers: C71.The author is indebted to Clement Wen for many helpful comments and he is also very grateful to a referee who proposed several helpful comments to improve the paper.     

Market overreaction and investment strategies

We investigated the overreaction of the Korean market in response to shocks in the US stock market, and analysed the dynamic relationship between these two markets since 1996. We found that the KOSPI 200 index futures overreacted to the S&P 500 index returns during the period from 2000 to 2009 when the Korean market was in its growth stage. As the Korean market matured and the KOSPI 200 overnight futures were introduced in 2009, the overreaction disappeared. When investors employed the Kelly model or Value-at-Risk to exploit the overreaction, their trading strategies produced significant profits during the growth stage even after considering transaction costs and risk, but the profits attenuated once the overnight futures market was launched in 2009.     

The Role of Central Government in Tax Competition Between Heterogenous Regions

This paper analyzes the role of central government in a Nash tax competition between two heterogenous regions, which differ in their endowments of two production factors. Regional governments use a source-based unit tax on mobile capital to finance their public service expenditures. The central government employs excise subsidies and lump-sum taxes to induce the two regions to efficient resource allocations. We answer to the question that whether the central government can induce an efficient equilibrium, and investigate the effects of endowments difference on the optimum subsidy rates. We find that there exists a unique tax rate under which the efficiency is achieved. We identify the set of endowment allocations for which the subsidy rate to one region is higher (or lower) than the subsidy rate to the rival. The large poor region receives a higher subsidy than the small rich region, but the subsidy to the small poor region may be higher or lower than that to the large rich region. [H2]     

A form of government organization from the perspective of transaction cost economics

Taking the approach of the superfirm, we characterize government organization through six different features. First, citizens are viewed as sovereign owners of a superfirm; elected officials are employees of the sovereign citizens. Second, in analogy to the economic principle of the division of labor and specialization, a division of labor between five independent branches of government is advocated: the legislative, the budgetary, the executive, the law enforcement, and the judiciary branch. Third, we do not suggest a mechanism of checks and balances between government branches but deal with the threat of tyranny using the principle of separation of decision control and decision management developed by Eugene Fama and Michael Jensen. Fourth, with election as a decision control device, we demarcate the constituency of the budgetary branch by age groups to provide an explicit control mechanism for intertemporal and intergenerational trades. Fifth, to strengthen sovereign citizens' decision control, the powers to recall elected chief public servants, to declare emergency and war, to sign into international treaties, and to amend the constitution are vested with a national assembly. Sixth, there is no head of state.     

A NICE agenda for IMP research

The IMP (Industrial Marketing and Purchasing) Group has engaged in a number of interesting developments in the past few years. Particularly adventurous have been the agendas of ‘pictures’ and sense-making and of time. In this paper we argue that borrowing and combining contemporary foci within social science on narratives, identity, culture and epoché temporality (for which we use the acronym N.I.C.E) allows the construction of an approach that can integrate these IMP agendas into a new research direction for the group that will keep it at the leading edge of marketing research. The purpose of our paper is to introduce and integrate discursive and temporal elements into the understanding and research of business networks to develop a more dynamic and hermeneutic approach. Our purpose is to provide a contribution to the field in exploring how identities are formed within business networks through narrative episodes in interconnecting relationships over time. We bring together all of the elements of a NICE agenda in an attempt to provide an integrative, ‘multi-lens’ theory of business networks focussed within the IMP research tradition. In doing so, we construct meaning as itself networked; sense-making involves relating presently narrated episodes to symbolic and material aspects of other narrative network episodes and events through emplotment and storying.     

A bootstrap test for jumps in financial economics

An i.i.d. bootstrap is applied for the ratio test of Barndorff-Nielsen and Shephard (2006) for jumps in jump diffusion processes. Asymptotic validity is established for the bootstrap test both under the null of no jump and under the alternative of jumps. Finite sample simulation shows that the bootstrap test has more stable size than the ratio test of Barndorff-Nielsen and Shephard (2006).     

External knowledge search,innovative performance and productivity in the Korean ICT sector

In recent years, Korea’s Information and Communication Technology (ICT) industry has grown rapidly. The prosperity of the ICT industry has brought growing recognition that rising productivity and innovative performance have made major contributions to ensuring competitive advantage in international markets. In this context, recent studies stress the importance of external knowledge for improving both innovative performance and productivity. This paper empirically investigates the effects of firms’ external knowledge search behavior on their productivity as well as their innovative performance in the Korean ICT manufacturing sector. Based on firm-level data from the Science and Technology Policy Institute (STEPI), this study indicates that incremental innovation and productivity are both related to external knowledge search.     

International Trade Finance and Exports: Evidence from Korean Bank-Intermediated Trade Finance Instruments

This paper investigates the effects of trade finance shocks on real exports by using novel data on two bank-intermediated instruments of trade finance in Korea: foreign trade loans extended by commercial banks and documentary bills purchased by them. Using a vector autoregression (VAR) model, the results show that a negative shock to both instruments adversely affects exports, particularly the exports of small and medium-sized enterprises (SMEs). The trade financing condition explains as much as 10–14 % of the variation in exports, which is comparable to the estimates in previous studies. Noteworthy is that the effects of trade finance on SME exports vary upon whether it is pre- or post-shipment financing.
