This paper studies how tax-and-transfer progressivity influences aggregate fluctuations when interacting with household heterogeneity. Using a simple static model of the extensive margin labor supply, we analytically characterize how a degree of progressivity influences differential labor supply...

A government plan was announced to expand the share of renewable energy to 20 percent by 2030 in Korea and to construct additional pumped hydro storage (PHS) to prepare for the uncertainty of renewable generation. However, due to the distortion of the Korean electricity market, pumped storage...

We develop the theory of stability for aggregate matchings used in empirical studies and establish fundamental properties of stable matchings including the result that the set of stable matchings is a non-empty, complete, and distributive lattice. Aggregate matchings are relevant as matching...

We study a dynamic matching environment where individuals arrive sequentially. There is a tradeoff between waiting for a thicker market, allowing for higher-quality matches, and minimizing agents' waiting costs. The optimal mechanism cumulates a stock of incongruent pairs up to a threshold and...

This paper investigates how effective safety education reduces workforce risks by using an establishment-level dataset in South Korea. We focus on identification and estimation of causal effects. Since provision of safety education depends on establishment’s decision, the main variable of...

We consider the impacts of a new information and communications technology, referred to as the Fourth Industrial Revolution (4IR) technology, on firm productivity by using a Korean dataset. We estimate the total factor productivity (TFP) of each firm using the control function approach for...

Intermittent demand refers to the specific demand pattern with frequent periods of zero demand. It occurs in a variety of industries including industrial equipment, automotive and specialty chemicals. In some industries or some sectors of industry, even majority of products are in intermittent...

Purpose: This study aims to investigate whether CEO future focus leads to improvements in the CSP. Although there has been extensive research on the antecedents of CSP, little has addressed the role of CEOs' subjective biases in determining how future time frames affect CSP. This study fills...
