Cross-shareholding network and corporate bond financing cost in China

This study examines the effect of cross-shareholding network centrality on the cost of corporate bond financing. Based on a sample of Chinese A-share listed firms that issued general corporate bonds from 2007 to 2018, we adopt a social network analysis method and use three indicators (Degree, Betweenness, and Eigenvector) and the principal factor (Composite) extracted from them to measure the firms’ centrality in the cross-shareholding network. We find that bondholders’ demand lowers bond yield spreads for firms with higher cross-shareholding network centrality. In further analyses, we explore the impact mechanisms using mediator models and find that such centrality promotes resource accessing, information disclosure, and corporate governance, thus decreasing corporate bond financing cost. In addition, we incorporate the moderate effect of geographical location and find that the relationship between cross-shareholding network centrality and corporate bond financing cost is more significant in firms located in remote places.     

Short-term disability in solid tumor patients with bone metastases and skeletal-related events

Abstract

Objective:

The skeleton is a common site of metastasis in patients with solid tumors. These patients often experience pain and reduced quality-of-life. This analysis evaluated the time and costs associated with short-term disability use among solid tumor patients with bone metastases (BM) and skeletal-related events (SREs).

Methods:

Data from patients 18–64 years old with solid tumors and BM, eligible for short-term disability benefits between January 1, 2002 and December 31, 2010, were extracted from MarketScan Research Databases. Short-term disability hours and costs associated with BM and SREs were evaluated.

Results:

Overall, 1098 patients met the criteria. For all patients with BM, the monthly mean short-term disability hours were 17.7?h pre-BM diagnosis and increased to 60.2?h post-BM diagnosis (p?<?0.001). The corresponding mean monthly short-term disability costs were $277 and $963 in the pre- and post-BM diagnosis periods, respectively (p?<?0.001). Monthly mean short-term disability hours were higher for the cohort of patients with SREs (21.2?h pre-SRE diagnosis and 67.4?h post-SRE diagnosis) than for those without an SRE (8.6?h pre-SRE diagnosis and 14.4?h post-SRE diagnosis) (p?<?0.001). Similarly, the corresponding monthly mean short-term disability costs were higher for patients with SREs ($625 and $1259 pre- and post-SRE diagnosis, respectively) than for patients without an SRE ($452 and $612 pre- and post-SRE diagnosis, respectively) (p?<?0.001). Results of a multivariate analysis indicated that SREs were associated with an additional 39.4 short-term disability hours and $613 in short-term disability costs per month (p?<?0.001).

>Conclusion:

Short-term disability hours and costs increased significantly when patients with solid tumors developed BM and SRE.     

A coupled Markov chain approach to credit risk modeling

We propose a Markov chain model for credit rating changes. We do not use any distributional assumptions on the asset values of the rated companies but directly model the rating transitions process. The parameters of the model are estimated by a maximum likelihood approach using historical rating transitions and heuristic global optimization techniques.We benchmark the model against a GLMM model in the context of bond portfolio risk management. The proposed model yields stronger dependencies and higher risks than the GLMM model. As a result, the risk optimal portfolios are more conservative than the decisions resulting from the benchmark model.     

Convexity theory for the term structure equation

We study the convexity and model parameter monotonicity properties for prices of bonds and bond options when the short rate is modeled by a diffusion process. We provide sharp conditions on the model parameters under which the convexity of the price in the short rate is guaranteed. Under these conditions, the price is decreasing in the drift and increasing in the volatility of the short rate. We also study the convexity properties of the logarithm of the price and find simple conditions on the coefficients that guarantee that the price is log-convex or log-concave.      

The use of credit default swaps by bond mutual funds: Liquidity provision and counterparty risk

Corporate bond mutual funds increased their selling of credit protection in the credit default swaps (CDS) market during the 2007–2008 financial crisis. This trading activity was primarily in multi-name CDS, greater among larger and established funds, and directed toward counterparty dealers in financial distress. Funds that sold credit protection during the crisis experienced greater credit market risk and superior post-crisis performance, consistent with higher expected returns from liquidity provision. Funds using Lehman Brothers as a counterparty experienced abnormal outflows and returns of –2% immediately following Lehman's bankruptcy, suggesting that funds’ opportunistic trading in CDS exposed investors to counterparty risk.     

Inflation and the stock market: Understanding the “Fed Model”

The so-called Fed model postulates that the dividend or earnings yield on stocks should equal the yield on nominal Treasury bonds, or at least that the two should be highly correlated. In US data there is indeed a strikingly high time series correlation between the yield on nominal bonds and the dividend yield on equities. This positive correlation is often attributed to the fact that both bond and equity yields comove strongly and positively with expected inflation. Contrary to some of the extant literature, we show that this effect is consistent with modern asset pricing theory incorporating uncertainty about real growth prospects and habit-based risk aversion. In the US, high expected inflation has tended to coincide with periods of heightened uncertainty about real economic growth and unusually high risk aversion, both of which rationally raise equity yields.     

International portfolio flows and exchange rate volatility in emerging Asian markets

This paper investigates the effects of equity and bond portfolio inflows on exchange rate volatility using monthly bilateral data for the US vis-a-vis seven Asian developing and emerging countries (India, Indonesia, Pakistan, the Philippines, South Korea, Taiwan and Thailand) over the period 1993:01–2015:11. GARCH models and Markov switching specifications with time-varying transition probabilities are estimated in addition to a benchmark linear model. The evidence suggests that high (low) exchange rate volatility is associated with equity (bond) inflows from the Asian countries toward the US in all cases, with the exception of the Philippines. Therefore, capital controls could be an effective tool to stabilise the foreign exchange market in countries where flows affect exchange rate volatility.     

A preliminary model of spouse influence on managerial global assignment willingness

Using family systems theory as a conceptual framework, this research study proposes and tests a preliminary model that explains spouse willingness to relocate internationally and manager willingness to assume a global assignment. Previous research from the global assignments, international job relocation and dual-career couples' literatures has found that spouse attitudes often influence the attitudes of expatriates. However, few research studies have been conducted to determine the factors that influence spouse attitudes toward both short- and long-term global relocation opportunities. The present study attempts to build understanding in this under-researched area of international human resource management. By understanding more about this important phenomenon, top decision-makers and international human resource professionals can better identify and select those candidates who have family situations that will predispose them to accept global assignments. Data from questionnaires completed by 427 global managers and 167 spouses were used to test hypotheses that examined the relationships between individual, family and organizational, factors and spouse criterion variables. An additional hypothesis was tested to measure spouse influence on manager global assignment willingness. The data in the study were analysed by conducting structural equation modelling. Theoretical, methodological and practical contributions from the present study are provided.

Capital flight from the countries in transition: Some empirical evidence

This paper presents empirical evidence suggesting that the transition economies have tended to experience capital flight during periods of macroeconomic instability, such as high inflation and sharply declining output. The timing of these outflows, however, has differed somewhat across countries. Poland and Czechoslovakia experienced significant capital flight early in the transition process, but as reforms have progressed, capital outflows have slowed. By contrast, Russia registered a relatively steady flow of capital flight from 1991-94, with cumulative outflows totalling about $40 billion. Finally, capital flight from Hungary has been subdued, paralleling the gradual course of economic reforms and the country's comparative political stability.
