Research Papers in Progress
Job Market Paper: “Irrationality under Uncertainty: how you can make better forecast” with Dr. Keith Gamble
The present is easier to “forecast” than the future. Many researchers have theoretically
emphasized the importance of the discount rate in evaluating present versus future
utility and many experiments have been devised to investigate what Kahneman and Tversky
(1973, 1979, 1986) claim in the prospect theory. This study aims at understanding
the role of subjective probabilistic inference in updating information for decision-making
procedures under uncertainty. Using hypothetical survey experiments, we investigate
the effects of subjective probabilistic inference on intertemporal choices. By adding
uncertainty on trade-offs in decision-making criteria, it induces more inconsistent
present preferences. We find that subjective probabilistic inference had an effect
on a given acquisition of information.
Subjective probabilistic inference plays a central role in many everyday cases of
forecasting, and as a result of forecasting exert substantive constraints on cognitive
processes, shaping a type of restriction or stimulus in decision-making procedures.
Under uncertainty, time preference is based on the hidden choice criteria formed by
subjective probabilistic inference and result from shaping the combination of "fear
of losses" and "capability of applying information".
Working Paper: “Subjective Inferences” with Dr. Keith Gamble
The purpose of this study is to build a foundation that allows us to draw possible explanations of choice behaviors which can be represented by time preferences or risk preferences. To conduct a dynamic preference reversal experiment is also the goal of this study. Using subjective Bayesian update analysis, each agent's different foresight ability for future returns is the key possibility in intertemporal choices. We focus on statistical inference abilities based on the Bayesian analysis. We find that base-rate fallacy negatively affects people's ability to update information which results in different foresight. These effects are thought to be unconsciously reflected in the results chosen by each individual. Our framework presents the conditions of preference arising from incomplete predictions for the future. It explains that the risk preference due to uncertainty and the individual’s probabilistic inference influence the difference in forecasts for each individual’s future reward, which reveals the present preference or reversal of time preference.
Working Paper: “Mortgage: should I buy this mortgage points?”
The disease epidemic has plagued human society, at least from the beginning of record-breaking history. As COVID-19 began to spread throughout the United States in 2020, each household have to adjusted how they live and work in response to uncertainty and they have to also quickly changed how and where they spend their money. Despite the Coronavirus (COVID-19) pandemic, U.S. mortgage performance has continued to improve, with the delinquency rate falling for 27 consecutive months and the serious delinquency rate and foreclosure rate hitting record lows, but the unemployment rate hit a record high in more than 80 years in April 2020, causing homeowners to lose their ability to pay back their monthly mortgage loans. With low interest rates creating a financially bright spot in the COVID-19 pandemic, many households are refinancing their mortgage loans to save money. Although positive factors of ultra-low interest rates have occurred, financial options such as various financial fees and time horizons that households might evaluate, have many different attributes. During decision-making procedures, they may improperly weigh these factors. Many mistakes can result from not considering good financial choices. This paper notes what characteristics of each household judge given information appropriately or improperly. I concentrate on the behavior of homeowners with mortgage, especially refinancing.
Working Paper: “Trade Liberalization and Job Polarization”, with W. Suwanprasert [submitted]
In this paper, we extend Yeaple (2005) to study the effects of trade liberalization on the job polarization phenomenon in the labor market. We show that trade liberalization causes a reallocation of workers between sectors that results in the job polarization phenomenon, and margins of change in technology and wage distribution resulting in income inequality. Additionally, this study investigates how much a reduction in transportation costs benefits high-skill and low-skill workers, while it hurts middle-skill workers. In conclusion, international trade raises the average wage in the economy, while also deepening income inequality.
