Human capital and FDI: Development process of the developing country in an overlapping generation model

We construct an overlapping generation model with human capital accumulation to analyze the effect of human capital level on foreign direct investment (FDI) in a small open developing country. In particular, we assume that manufactured goods have the human capital intensive technology and young agents choose whether to work or to educate themselves. When the human capital level in the developing country is sufficiently small, manufactured goods firms do not conduct FDI and the economy in the developing country is trapped in poverty. If the government of the developing country levies a tariff on the imports of manufactured goods, manufacturers conduct FDI, and the economy in the developing country can escape from the poverty trap.     

Why Tour Guiding is Important for Ecotourism: Enhancing Guiding Quality with the Ecotourism Promotion Policy in Japan

The Ecotourism Promotion Policy in Japan requires tour guiding to be employed, although it provides little rationale for it. This paper reviews the literature to illustrate why tour guiding is important for achieving policy and ecotourism goals in order to support this requirement. An overview of ecotourism policy in Japan is provided, contributions of tour guiding to achieving the policy and ecotourism goals are described, and approaches to strengthening current practices along with the policy are discussed. It is suggested that non-profit organizations offer training to impart knowledge about guiding roles and interpretation at a national level and that ecotourism promotion councils teach knowledge about ecotour products and tourists at a regional level.     

Real interest rate equalization: some empirical evidence from the three major world financial markets

This article examines the linkage of real interest rates of the three major world financial markets (USA, Japan and the UK) with the use of cointegration methods. Unlike previous works, the investigation uses a trivariate vector autoregressive (VAR) model in which a constant term in the common stochastic trends space is excluded. Based on data generated after the liberalization of Japan's foreign exchange market at the end of 1980 (1981:1–1998:12), the article finds some empirical evidence indicating that the extent of the departure from the long-run real interest rate equalization (RIE) is not very large, although the null hypothesis of the long-run RIE is rejected in most cases.     

Application of Homotopy Analysis Method to Option Pricing Under Lévy Processes

Option pricing under the Lévy process has been considered an important research direction in the field of financial engineering, where a closed-form expression for the standard European option is available due to the existence of analytically tractable characteristic function according to the Lévy–Khinchin representation. However, this approach cannot be applied to exotic derivatives (such as barrier options) directly, although a large volume of exotic derivatives are actively traded in the current options market. An alternative approach is to solve the corresponding partial integro-differential equation (PIDE) numerically, which is, in fact, time-consuming and is not computationally tractable in general. In this paper, we apply the so-called homotopy analysis method (HAM) to solve the corresponding PIDE in a semi analytic form, being obtained from the following three steps: (1) Apply the Fourier transform to convert the PIDE to an ordinal differential equitation (ODE), and construct a differential system of ODEs. (2) Solve the system of ODEs, where each differential equation is shown to have an analytical solution. (3) Express the option price using the sum of infinite series, where each term may be expressed analytically and derived by applying Steps (1) and (2) recursively. To illustrate our technique more precisely, we take the variance gamma model as an example and provide the semi-analytic form. Numerical examples demonstrate a fast convergence of our proposed method to the prices of European and down-and-out call options with a few number of terms. Note that this method is easy to implement and can be applied to other types of options under general Lévy processes.     

Reputation and turnover

We consider a repeated duopoly game where each firm privately chooses its investment in quality, and realized quality is a noisy indicator of the firm's investment. We focus on turnover equilibria in which a low‐quality realization is penalized by lowering future demand of the firm that delivered this quality. We determine when a turnover equilibrium that gives higher welfare than the static equilibrium exists and how this relates to market fundamentals. We also derive comparative statics properties, and we characterize a set of investment levels and, hence, payoffs that turnover equilibria sustain.     

A politically feasible social security reform with a two-tier structure

This paper investigates the welfare implications and political feasibility of social security reforms with a two-tier structure in Japan. We evaluate social security reforms from two points of view: (i) the ex-ante expected value of future generations, and (ii) whether current generations prefer reform to the status-quo system, which we call political feasibility. To evaluate the reforms, we use a large-scale overlapping generations model with idiosyncratic income risk and a two-tier structure. The first tier guarantees a basic pension and the second tier consists of the earnings-related part. Calibrating the parameters of the model to the Japanese economy, we compute the transition path and the two welfare criteria. We find that, given the two-tier structure in Japan, an increase in the basic pension and the abolition of the earnings-related part of the social security system improve the welfare of future generations, and ensures political feasibility when a consumption tax is the source of revenue.     

Bi-objective decision support system for routing and scheduling of hazardous materials

This paper presents a Pareto-based bi-objective optimization of hazardous materials vehicle routing and scheduling problem with time windows and shows its application to a realistic hazardous material logistics instance. A meta-heuristic solution algorithm is also proposed, which returns a set of routing solutions that approximate the frontier of the Pareto optimal solutions based on total scheduled travel time and total risk of whole transportation process. It works in a single-step fashion simultaneously constructing the vehicle route and selecting the optimal paths connecting the routed locations from a set of non-dominated paths obtained in terms of travel time and risk value.     

Predicting the intentions of tourism major students in a Korean University to acquire foreign language skills

The theory of planned behaviour was used to examine intentions of Korean tourism major students to acquire foreign language skills (FLS) and uncover the beliefs that contribute to that intention. Belief elicitation and belief measurement questionnaires were collected from 38 and 242 students at Woosong University in November and December 2010. Attitudes and subjective norms were found to be significant contributors to the sample students' intention to acquire FLS. Favourable attitudes and perceived social pressure should be maintained by targeting the behavioural beliefs and normative beliefs to heighten the intention level.     

Saying Sayonara to the Farm: Hierarchical Bayesian Modeling of Farm Exits in Japan

Off‐farm employment opportunities are thought to have an effect on farm exit rates, though evidence on the sign of this effect has been mixed. Examining this issue in the context of Japanese agriculture, we find that farm exits are related to off‐farm income as a share of household income, and more specifically to the nature of off‐farm work. Two econometric models are developed: a hierarchical Bayesian linear model and a hierarchical Bayesian Poisson model. Both models perform well in predicting exit rates across the towns and prefectures of Japan.     

Why does the trend extracted by the Hodrick–Prescott filtering seem to be more plausible than the linear trend?

Why does the trend extracted by the Hodrick–Prescott (HP) filtering (HP trend) seem to be more plausible than the linear trend estimated by OLS? This article provides an answer for it. Because the HP filtering is a basic econometric tool, it is necessary to have a precise understanding of the nature of it. This article concludes that the HP trend is calculated by adding the low-frequency component (the long-term periodic fluctuation) of the linearly detrended series to the linear trend, which leads to that the HP trend seems to be more plausible than the linear trend. Other than this key result, this article shows that the HP cycle, which is defined as the residuals of the HP filtering, can be interpreted as the high-frequency component (the short-term periodic fluctuation) of the linearly detrended series. An empirical illustration is also provided.
