This study develops cluster robust inference methods for panel quantile regression (QR) models with individual fixed effects, allowing for temporal correlation within each individual. The conventional QR standard errors can seriously underestimate the uncertainty of estimators and, therefore,...

This paper establishes monotonicity of the chi-square test statistic. As the more efficient parameter estimator is plugged into the test statistic, the degrees of freedom of the resulting chi-square test statistic monotonically increase.

Demsetz and Lehn (1985), Morck, Shleifer, and Vishny (1988), and McConnell and Servaes (1990) report different empirical findings regarding ownership structure and corporate profitability. In this paper, we re-estimate the relation between management ownership and firm's value after controlling...

This paper empirically analyzes the call timing of callable bonds to see how refunding opportunity, cost of financial distress, agency cost of debt, and private information affect the call decision. The empirical results show that firms issue callable bonds, convertible or not, to enjoy future...

This article develops parametric and semi-parametric, maximum likelihood estimation methods of the proportional hazard model for the case when durations are grouped and heterogeneity is not fully measured. This article also extends Ryu's (1994b) specification tests for the proportional hazard...

Workers who lose their jobs can become re-employed either by being recalled to their previous employers or by finding new jobs. Workers' chances for recall should influence their job search strategies, so the rates of exit from unemployment by these two routes should be directly related. We...

This paper studies the issue of designing an optimal organizational form: design for sub-units' task allocation, decision-making structure, and incentive schemes for organizational members. Depending on the way tasks are allocated between the sub-units, and whether decision-making is centralized...

Economic forecasts are quite essential in our daily lives, which is why many research institutions periodically make and publish forecasts of main economic indicators. We ask (1) whether we can consistently have a better prediction when we combine multiple forecasts of the same variable and (2)...

This paper addresses the issue of catching and convergence at the level of firms, and investigates whether Korean firms tend to converge toward mature firms represented by the US firms in terms of their behavior and performance as well as firm-level innovations systems. It conducts regression...
