Professor Changsoo Kim's research lab focuses on the intersection of behavioral economics, environmental health, and social inequality, with a particular emphasis on how macro-level environmental factors—such as air pollution—affect cognitive health and mental well-being, especially among aging populations. The lab also investigates the socio-economic implications of corporate marketing practices, particularly the 'customer is king' paradigm, and its impact on power dynamics in high power distance cultures. Research spans empirical macroeconomic modeling of corporate liquidity decisions and epidemiological analysis of environmental exposures. The lab integrates economic theory with public health and behavioral science to address pressing societal challenges.

We model the firm's decision to invest in liquid assets when external financing is costly. The optimal amount of liquidity is determined by a tradeoff between the low return earned on liquid assets and the benefit of minimizing the need for costly external financing. The model predicts that the optimal investment in liquidity is increasing in the cost of external financing, the variance of future cash flows, and the return on future investment opportunities, while it is decreasing in the return
Conclusions: A transient increase in particulate matter was associated with increased suicide risk, especially for individuals with preexisting cardiovascular disease.
<b>Background/Aim:</b> Given a fast-growing aging population in South Korea, the prevalence of cognitive impairment in elderly is increasing. Despite growing evidence of air pollution exposure as one of the risk factors for declining cognition, few studies have been conducted on gender difference in the relation of cognitive function associated with outdoor air pollution. The aim of this study is to investigate the effect modification of gender difference in the association between cognitive fun
Purpose This study aims to examine how the modern marketing expectation of treating the customer like a king can become a source of power differential in societies that already have a predisposition for hierarchical structures. The authors explore how this marketing-generated power differential might have an adverse impact on service providers in Eastern cultures with high power distance. Design/methodology/approach Four studies involving receivers and providers of services in Canada and South K
