This article is part of an ongoing investigation of the combinatorics of $q,t$-Catalan numbers $\textrm{Cat}_n(q,t)$. We develop a structure theory for integer partitions based on the partition statistics dinv, deficit, and minimum triangle height. Our goal is to decompose the infinite set of partitions of deficit $k$ into a disjoint union of chain...

Sixty companies on the inaugural “Fortune 500” list still remained on this list in 2020 and they have monotonically increased their leverage (median debt to total assets ratio rose from 0.5% to 20.4%) over the past 70 years. This study applies factors from classic capital structure theories to this sample and explains the dynamic choice of debt usa...

This study investigates the speed of adjustment (SOA) to target leverage for different industry sectors in Malaysia. Using the two-step system generalized method of moments for 415 non-financial firms from 2010 to 2021, we found that the SOA for the overall sample is 38.6% and 22.0% for total debt and long-term debt, respectively. Our paper reveals...

In a cluster of news texts on the same event, two sentences from different documents might express different multi-document phenomena (redundancy, complementarity, and contradiction). Cross-Document Structure Theory (CST) provides labels to explicitly represent these phenomena. The automatic identification of the multi-document phenomena and their...

This paper analyzes the impact of capital structure on financial performance of listed firms in the Hanoi stock exchange. The panel data of 383 listed firms in the period 2015-2019 were regressed by pooled least squares regression model (Pooled OLS), fixed effect model (FEM) and random effect model (REM). The results show that capital structure neg...
