Social signals predict contemporary art prices better than visual features, particularly in emerging markets.

What determines the price of an artwork? This article leverages a comprehensive and novel dataset on art auctions of contemporary artists to examine the impact of social and visual features on the valuation of artworks across global markets. Our findings indicate that social signals allow us to predict the price of artwork exceptionally well, even approaching the professionals' prediction accuracy, while the visual features play a marginal role. This pattern is especially pronounced in emerging markets, supporting the idea that social signals become more critical when it is more difficult to assess the quality.

Integration of Pakistan's stock market with the stock markets of top ten developed economies.

This study examines the integration of Pakistan's Stock Market with the stock markets of the top ten largest economies in the world-USA, China, Japan, Germany, the UK, India, France, Italy, Brazil, and Canada-from January 2015 to October 2020. To examine long- and short run integration, this study employed Johansen and Juselius co-integration and pair-wise Granger causality tests. In the long run, the results indicated that Pakistan's Stock Market is not integrated with these markets.

Economic development, intergenerational mobility, and health in South Korea.

A growing number of studies reported the association between social mobility and health. However, few studies investigated whether the association varies by age group. Drawing on the economic environment that facilitated social mobility in South Korea, we postulate each age group had a different extent of social mobility, which would vary with the extent of economic growth and affect the association between social mobility and health.

Impacts of the COVID-19 crisis on single-person households in South Korea.

Using nationally representative income and expenditure data from South Korea, we show that single-person households suffered a much greater decrease in household income and expenditure compared to multi-persons households during the COVID-19 pandemic in 2020. Negative effects on income were largest for the single-person households in ages 50-64, mostly driven by decreases in earned income rather than business income. There was no corresponding decrease in consumption expenditures, however, other than on transportation expenditure for young men.

Demand risk transfer and government's cost efficiency: Focusing on Korean waste treatment PPP cases.

This study aimed to examine the government's cost efficiency considering the high-risk/high-return mechanism of PPP. Faced with increasing demand but with limited budget, the Korean government has relied on the Public-Private Partnership (PPP) to provide waste treatment services for the last couple of decades to expand fiscal space. However, most of waste treatment facilities projects have been promoted using the BTO (Build-Transfer-Operate) method with high rate of return due to the demand risk that is transferred to the private.

The long-term effects of labor market entry in a recession: Evidence from the Asian financial crisis.

This study investigates the long-term effects of initial labor market conditions by comparing cohorts who graduated from college before, during, and after the 1997-1998 Asian financial crisis in South Korea. We measure the overall welfare effect by examining their labor market activities, family formation, and household finances. Using data from 20 waves of the Korean Labor and Income Panel Study, we find a substantial and persistent reduction in employment, earnings, marriage, fertility, and asset building among men who graduated during the recession.

Collaborative accountability for sustainable public health: A Korean perspective on the effective use of ICT-based health risk communication.

The sustainability of public health practices requires collaboration between the government and its citizens. On the government's side, social media can provide a conduit for communicating health risk information in an effective and timely fashion, while also engaging citizens in informed decision-making. On the citizen's side, information communication technology (ICT)-based practices cannot function unless citizens recognize and act on their responsibility to actively engage with government social media platforms.

The impact of employment protection on health: Evidence from fixed-term contract workers in South Korea.

In this paper, we examine the impact of increased employment protection on the self-rated health of workers. We utilize the recent labor reform in South Korea which sharply increased the employment protection level of fixed-term contract workers meeting certain criteria. By applying a difference-in-differences framework to longitudinal data, we explore the causal impact of employment protection.

Hypertension and Health-Related Quality of Life (HRQoL): Evidence from the US Hispanic Population.

Background And Objective: Little evidence exists regarding the marginal decrease in health-related quality of life (HRQoL) in relation to the presence of hypertension among a Hispanic population based on US population-based research.

Method: This cross-sectional study used data from the 2014 to 2015 Medical Expenditure Panel Survey (MEPS). The target population was comprised of Hispanic community-dwelling residents with hypertension in the USA.

Measuring the Effects of Employment Protection Policies: Theory and Evidence from the Americans with Disabilities Act.

Title I of the Americans with Disabilities Act (ADA) is an employment protection policy for disabled workers. By exploiting cross-state variation in pre-ADA legislation, we measure the effects of the law on transition rates of disabled workers. We find a decline in employment-to-non-employment transitions after the ADA, with an insignificant change in flow into employment.

Developing a Basic Scale for Workers' Psychological Burden from the Perspective of Occupational Safety and Health.

Background: Organizations are pursing complex and diverse aims to generate higher profits. Many workers experience high work intensity such as workload and work pressure in this organizational environment. Especially, psychological burden is a commonly used term in workplace of Republic of Korea.

Oral Cholera Vaccination Delivery Cost in Low- and Middle-Income Countries: An Analysis Based on Systematic Review.

Background: Use of the oral cholera vaccine (OCV) is a vital short-term strategy to control cholera in endemic areas with poor water and sanitation infrastructure. Identifying, estimating, and categorizing the delivery costs of OCV campaigns are useful in analyzing cost-effectiveness, understanding vaccine affordability, and in planning and decision making by program managers and policy makers.

Objectives: To review and re-estimate oral cholera vaccination program costs and propose a new standardized categorization that can help in collation, analysis, and comparison of delivery costs across countries.

How Was the Weekend? How the Social Context Underlies Weekend Effects in Happiness and Other Emotions for US Workers.

In this paper we estimate the size of weekend effects for seven emotions and then explore their main determinants for the working population in the United States, using the Gallup/Healthways US Daily Poll 2008-2012. We first find that weekend effects exist for all emotions, and that these effects are not explained by sample selection bias. Full-time workers have larger weekend effects than do part-time workers.
