Cave Tourism: Tourists' Characteristics,Motivations to Visit,and the Segmentation of Their Behavior

Geotourism is one among many types of ecotourism or nature tourism. Cave tourism within geotourism has gained popularity in Korea. The study's objectives include cave tourists' characteristics, segmenting them according to motivation factors, and finally identifying who they are. The sample population for this research consisted of tourists who have visited the Hwansun Cave in Samchuk City. Among a total of 547 questionnaires distributed, 537 questionnaires were used for further data analyses. On the basis of cluster analysis using the motivation factors, cluster 1 was named an “escape-seeking group”, cluster 2 was termed a “knowledge- and novelty-seeking group”, cluster 3 was called a “novelty-seeking group” and cluster 4 was termed a “socialization group”. Differences in socio-demographic variables, beliefs about cave tourism resources, preferred cave tourism products, satisfaction with this tour, willingness to participate in another cave tour and belief in the value of cave tourism resources were found among the four clusters. The study's findings were expected to be helpful in understanding who they are.

Optimal excess-of-loss reinsurance and dividend payments with both transaction costs and taxes

In this paper we study the optimal excess-of-loss reinsurance and dividend strategy for maximizing the expected total discounted dividends received by shareholders until ruin time. Transaction costs and taxes are required when dividends occur. The problem is formulated as a stochastic impulse control problem. By solving the corresponding quasi-variational inequality, we obtain analytical solutions for the optimal return function and the optimal strategy.     

Some results on the compound Markov binomial model

Abstract

Some years ago, in the course of an analysis of upper and lower limits for incomplete moments of statistical distributions I established an elementary summation formula¹ which proved rather useful for the purpose I had in view. Subsequently the formula was generalized by professor Steffensen, who showed² that the formula in question could be looked upon as giving the first term of an expansion in a certain type of series. Professor Steffensen established recurrence formulae for the coefficients of the series and computed the second, third and fourth term and the corresponding remainders¹, but did not arrive at a general, explicite expression for the coefficient of the n-th term and the corresponding remainder. A year later I found these expressions accidentally while I was working on some other problem. I also discovered the real nature of the procedure in question which proved to be a certain kind of least square fitted polynomial approximation. I did not, however, at the time publish the result. Taking the question up again later I found that the whole problem could be considerably generalized. The type of generalization in question is analogous to the generalization from polynomials to arbitrary functions.     

On indeterminacy and growth under progressive taxation and productive government spending

We examine the theoretical interrelations between equilibrium (in)determinacy and economic growth in a one‐sector representative‐agent model of endogenous growth with progressive taxation of income and productive flow of public spending. We analytically show that, if the demand‐side effect of government purchases is weaker, the economy exhibits an indeterminate balanced‐growth equilibrium and belief‐driven growth fluctuations when the tax schedule is sufficiently progressive or regressive. If the supply‐side effect of public expenditures is weaker, indeterminacy and sunspots arise under progressive income taxation. In sharp contrast to traditional Keynesian‐type stabilization policies, our analysis finds that raising the tax progressivity may destabilize an endogenously growing economy with fluctuations driven by agents’ self‐fulfilling expectations.     

资产价格、货币政策与相关政策协调

本文扩展了最优货币政策规则模型,考察了货币政策与其它逆周期调控政策的配合问题.通过理论分析和数字模拟,结果显示多种政策工具的配合确实能够更有效地稳定资产价格及宏观经济;我们的研究还表明,即使在有其它工具配合的情况 下,货币政策仍需要对资产价格波动进行适当反应.     

Are consumers' financial needs and values common across cultures? Evidence from six countries

Are consumers' financial needs, and financial values, the same or different across cultures? Two studies, with student (Study 1; n = 988) and non‐student (Study 2; n = 959) participants, explore the extent of equivalence, across six countries (Brazil, Russia, China, Taiwan, Tunisia and US), in financial need belief, and financial value, measurement models. The financial need beliefs, derived from self‐determination theory (SDT) principles, include financial self‐efficacy, financial autonomy, financial community trust and support; the financial values include materialism and financial altruism. Both the financial need and financial value constructs evidence configural invariance (similar factor structure), and factor invariance among student but not non‐student samples. The financial need constructs evidence full, and the financial value constructs evidence partial, metric (factor loading) invariance. Factor covariance invariance obtains for the financial need beliefs constructs but not the financial value constructs. Finally, neither financial need nor financial value constructs evidence scalar (intercept) invariance. These results provide partial support for extending SDT's hypothesis of universal human needs to the financial domain. In contrast, the financial value constructs of altruism and materialism are largely instable across cultures, suggesting that consumer views of giving, and the role of wealth in social status, differ between countries.
