Abstract This study analysed the effect of an increase in the supply of youth college graduates, in terms of the return on education. The rate of return on education in Korea substantially dropped from 1983 to 1994. Since then, however, the declining trend of the rate of return on education stopped and turned upward. The rate of return has declined especially for college graduates, and such a decline has been most prominent for young cohorts, among college graduates, since 1987. The observed trend of the rate of return appears to be related to the sharp increase of labour supply of college graduates since the mid 1980s. The elasticity of substitution between education levels and age groups was estimated in this study, using a generalized demand-supply model. The effects of relative supply of college graduates (as a whole and by age) on the relative wages of college graduates by age were analysed under the assumption of constant skill-biased technological change. As it turned out, the relative college graduates’ labour supply of each age group had large bearings upon relative wages of each corresponding group, while the relative labour supply of all college graduates did not. It implies that labour is an imperfect substitute, not only between education levels but also between age groups. Thus, as youth college graduates’ supply increases, there needs to be a corresponding demand increase for them, to avoid the drop in the wage or employment level for them. Therefore, to tackle with the issues of youth labour market, such as youth unemployment, separate policies targeting the youth group are called for. 相似文献

We study the dynamic general equilibrium effects of introducing a social pension program to elderly informal sector workers in developing countries who lack formal risk sharing mechanisms against income and longevity risks. To this end, we formulate a stochastic dynamic general equilibrium model that incorporates defining features of developing countries: a large informal sector, private transfers as an informal safety net, and a non-universal social security system. We find that the extension of retirement benefits to informal sector workers results in efficiency losses due to adverse effects on capital accumulation and the allocation of resources across formal and informal sectors. Despite these losses recipients of social pensions experience welfare gains as the positive insurance effects attributed to the extension of a social insurance system dominate. The welfare gains crucially depend on the skill distribution, private intra-family transfers and the specific tax used to finance the expansion. 相似文献

We empirically analyze both free and paid products on the top 100 Free and Grossing charts in the Korea App Store using Weibull parametric survival analysis on the product level. The findings are as follows: First, influences of ranking, customer ratings, and contents size on product survival are different for free and paid products. Customer ratings and contents size critically affect product survival when the price is zero. Second, the early entrant advantage exists in App Store, which results from a ranking system in the App Store and consumer learning. However, the effect of early entrant advantage differs between the Free and Grossing charts; the benefit of early entrant advantage is greater on the Free chart than that on the Grossing chart. Finally, we provide a competitive profit model that is related to free products. 相似文献

This paper empirically investigates market behavior and firms?? lobbying in a unified structural setup. In a sequential game, where firms lobby for regulation before they compete in the product market, we derive a testable measure of lobbying coordination. Applying the setting to the early U.S. cellular services industry, we find that lobbying expenditures, as measured by campaign contributions, and market conduct were consistent with a one-shot Nash equilibrium and that price caps were binding on average. Furthermore, campaign contributions from cellular firms effectively lowered the burden of the price caps and reduced production costs. 相似文献

This study compares the size and nature of the gender earnings differentials for the self-employed and wage earners in Korea, taking into account the workers’ self-selection of each employment type. The two-stage estimates of the earnings equation, corrected for worker selectivity, are used to decompose the gender earnings differentials into productivity-related and discriminatory factors. Our results suggest that the size of the gender earnings gap is larger in the wage sector than in the self-employment sector, but not by large margin, and so is the discrimination effect when not controlled for worker selectivity. With worker selectivity controlled, the discrimination effect is greatly intensified in the wage sector, while it becomes not significant in the self-employment sector. These findings imply that the observed gender earnings gap in the wage sector is largely ascribed to discrimination against women, while the gender earnings gap in the self-employment sector is mostly due to productivity difference that, in part, is caused by worker selectivity. 相似文献

To explore the attitudes towards risky career choices of young people in highly competitive environments, we surveyed almost 1000 football players in the youth academies of German professional clubs (Bundesliga), who must generally decide early in their careers whether or not to risk quitting school to focus solely on a professional football career. Based on the survey responses, we empirically analysed which factors influence these youths’ tendencies to choose a high-risk career option over a lower risk one. Our results seem to indicate that such risk taking in competitive environments can be explained by potential benefits expected from this decision, as well as judgments about the likelihood of achieving the desired career. Risk attitudes towards career choices vary by differences in individuals’ estimates of the potential benefits and in particular, in their own assessments of the likelihood of success, which is an important driver of risk acceptance. We also found that opportunity cost considerations influence risk acceptance: the better the low-risk option, the less willing the individual to give it up for a high-risk alternative. In addition, both national origin and level of cultural integration play a role in attitudes towards risky career choices, with reductions in the latter increasing the risk premium of quitting school. 相似文献

This study examined factors (e.g., ad values and social networking advertising characteristics) influencing consumers' attitudes and behavioural intention towards three types of social networking advertising (SNA) on Facebook – home page ad, social impression ad, and organic impression ad. Findings demonstrate that peer influence had the most significant impacts on attitude and behavioural intention across all types of SNA. The significant interaction term of invasiveness and privacy concern indicates that both attitude and behavioural intention were diminished, particularly when perceived invasiveness and privacy concern were high simultaneously. In addition, results suggest that attitudes towards the ad played a mediating role between SNA characteristics and behavioural intention. Lastly, among the types of SNA, consumers preferred organic impression ads that featured friends' names on their newsfeed more than paid ads located on the sidebar of their Facebook pages. 相似文献

Amenity values of spatial configurations of forest landscapes over space and time in the Southern Appalachian Highlands 总被引:1,自引:0,他引:1
This research analyzes amenity values of spatial configurations of forest landscapes over space and time in the Southern Appalachian Highlands using geographically weighted regression (GWR) in a hedonic housing-price framework with a census-block group (CBG) dataset. Results show that housing-price response to mean forest-patch size and forest-patch density increased substantially between 1990 and 2000 in a few specific areas with economically significant amenity values. The spatial and temporal dynamics of the resulting amenity-value estimates are evaluated for potential use as site-selection indicators for implementation of forest conservation programs. 相似文献

Ethical Commitment,Financial Performance,and Valuation: An Empirical Investigation of Korean Companies 总被引:1,自引:0,他引:1
A variety of stakeholders including investors, corporate managers, customers, suppliers, employees, researchers, and government
policy makers have long been interested in the relationship between the financial performance of a corporation and its commitment
to business ethics. As a subject of research, the relations between business ethics and corporate valuation has yet to be
thoroughly quantified and investigated. This article is an effort to amend this inadequacy by demonstrating a statistically
significant association between ethical commitment and corporate valuation measures. Consistent with anecdotal evidence, we
have found a significant association between the ethical commitment of Korean companies and their valuation on the Korean
stock market. However, the result reveals that the association between ethical commitment and financial performance is not
significantly supported.
