This paper presents a series of path models that were developed to test whether financial risk tolerance mediates the association between the following four variables and investing behavior: (a) male and married, (b) female and married, (c) male and single, or (d) female and single. Data for this study were obtained from a proprietary consumer survey of risk-tolerance attitudes. Four path models were developed to test relationships among the variables in 2008, 2009, 2010, and 2011. These years were chosen to represent the depth and recovery periods in the Great Recession. The total number of respondents was 29,641. Findings showed that financial risk tolerance was positively associated with risky investing behavior (i.e., equity ownership) in each of the four periods. The associations among the gender-marital status variables and investing behavior were mixed; however, findings did indicate that risk tolerance mediates these relationships by sometimes amplifying and occasionally attenuating risky behavior. Based on the findings, implications and limitation are presented.

The focus of this article is on the process of cultivating students' interests so that they come to view mathematics as an activity worthy of their engagement. We first define and operationalize the notion of interests, in the process developing a perspective in which they are seen to be generative, to evolve, and to be deeply cultural. We concretize this perspective by presenting an analysis of a classroom design experiment that documents both the process by which the students' interests evolved and the means by which these developments were supported. We then frame the analysis as a case in which to tease out the implications for a nascent design theory of mathematical interests and in doing so give particular attention to the issue of equity in students' access to significant mathematical ideas

This Study examines the implications for event studies using the daily stock data. The output present the event study results. The event period is defined from 30 days before through 30 days after the event date, and is broken into four "windows" for abnormal return cumulation: the pre-event period, days -30 through -2; dajys -1 and 0, a period commonly investigated for the immediate impact of the event; and the post-event period, days +1 through +30. It shows how firm's information offerings affect the price process and consequent issues. The Patell Z test is an examples of a standardized abnormal return approach, which estimate a separate standard error for each security-event and assumes cross-sectional independence. The generalized sign test adjusts for the fraction of positive abnormal returns in the estimation period instead of assuming 0.5.

This study examines the implications on the valuations of privately held firms when stakes are acquired by venture capitalists in India. In addition, the effect of fund size and revenue multiple is considered as a determinant of firm value. The study is based on a sample of 1229 rounds of funding during the period 2007-2015. The data was obtained from Venture Intelligence. Three major observations emerged based on an OLS regression. Firstly, it is observed that the stake acquired by venture capitalists has a negative effect on firm value. It supports the belief that when a firm reaches its maximum valuation from the promoter's perspective, there is a tendency to liquidate additional stakes. Secondly, a positive association between the revenue multiple and valuation is recognized. Thirdly, the convex relationship (U-shaped) between the fund size and firm valuations as seen in the case of developed economies, appears to be non-existent in India.

Purpose - We investigate whether a potential missing pricing factor plays a significant role in the idiosyncratic volatility puzzle. Design/methodology/approach - We theoretically show how a missing pricing factor can affect the idiosyncratic volatility puzzle, and also show how to get around the problem empirically. We adopt the Fama-French five factor model for the estimation of the idiosyncratic risk and use randomly constructed portfolios as test assets. Findings - We find that a missing factor does not drive the idiosyncratic volatility puzzle. Thus, we conclude that the idiosyncratic volatility does affect the risk premium of its stock. Research implications or Originality - The Fama-French five factor model does a pretty good job in explaining the risk premiums of stocks, and it can be used to reliably estimate idiosyncratic risk of stocks.

This study is to understand how why users fail to service and how users use service recovery strategics. This study use equity theory to understand how perceived justices have influence on trust and to identify how trust has influence on service quality. This study used scenario techquie to get user experience of service failure in smartphone application. Scenario is composed of 16 sub scenario and we conducted survey with each case. The results show that interpersonal justice and distributed justice have significantly influence on trust. However, procedural justice has not influence on trust. Service quality is influenced by trust. This paper conclude with statements of implications and limitations of the study results.

This study examines the mobility of the disadvantaged population groups in terms of public transportation using the 2014 smart card data in Seoul, Korea. Particularly, we focus on the disadvantaged population such as senior group, junior group, and low-income population group. Based on the spatial distributions of public transportation mobility levels and the disadvantaged population groups, we identify specific areas where public transportation service should be improved for the disadvantaged population. As a result, we identify 15 administrative-dongs where the ratio of the disadvantaged population is high while the mobility index of public transit is low. The main contributions of this study are as follows. First, we use the smart card data which contains the information of actual trip made by individuals and develop the evaluation process of urban mobility for the disadvantaged population groups. Second, we identify the specific areas where public transportation service should be improved for the different group of the disadvantaged population. Lastly, we discuss policy implications to improve the urban mobility of the disadvantaged population.

Venture capital companies and funds play the following roles: to find small and medium-sized enterprises(SMEs) which face equity gap but possess high-growth potential, to make equity investment in such SMEs, and to intensively support the invested firms' growth in order to gain the maximum profits from the investment via maximization of the firms' values. This work discusses the issue of how such roles of venture capital can be used in a stable manner within individual non-Capital regions of Korea for fostering the start-up and growth of promising SMEs and thereby advancing local/regional economic development. The principal portion of my discussion deals with Regional Venture Capital Fund(RVCF) of UK and its policy implications for the Korean context. Additionally, the work conceptually explores roles of venture capital and local/regional development, and it empirically examines how such venture capital's functions are recently used for the business start-up and growth in the non-Capital regions of Korea.

Balanced regional development' is rehabilitated as contemporary national agenda by Roh government. The regional equity policies has been justified as insuring more 'even development opportunity'. It is required further examination that the intrinsic relationships between spatial equity and 'the participatory democracy' of the government. The participatory democracy was estimated an important method to achieve 'the alternative development' of the new social movement. But the rapid evolution of transportation and electronic nudes of communication technology strengthened spatial concentration, especially concentration of authoritative resources. These concentrations have a tendency of participation exclusion in the symbolic social practice such as ideological and political decision-making. In order to realize participatory democracy, It is not sufficient to decentralize administration authorities. The reallocation and upbringing policies of symbolic practices such as cultural industries and education facilities is very important.

Although educational facilities are important considerations from a social equity standpoint, the educational environment generally found in rural areas has been continuously deteriorated due to numerous social problems following birth rate declines and school abolition numbers. The purpose of this study is to evaluate the commuting accessibility changed by the abolition of elementary schools. The village-level accessibility is assessed following physical accessibility criteria based on legally defined commuting distances. Moreover, this study shows the implications of commuting accessibility by school district zones through comparing the minimum commuting distances with real commuting distance. The target area is the Gangwon state, the coverage area in which for schools is the widest in South Korea (44.1 ㎢/school). We evaluated the commuting distances to the nearest elementary school for 992 rural villages and 74 urban villages. Of the 1,066 villages in urban and rural areas evaluated, most of the villages (about 77%) are exposed to commutes to elementary schools were the marginal distance is over 1,000 meters. The annual rate of increase of commuting distance for 1,066 villages in Gangwon state has steadily increased by 2.8%p since 2000, average commuting distance from 2.8 km to 3.6 km. By the designation of the school districts, elementary school students have to go to a faraway school located within administrative district, even though there is a school nearby. It is expected that the results of this study will be made use of as basic data for the establishment of policies such as a reasonable basis for closing schools measurements considering the locally unique environment.
