Disappointment aversion and the equity premium puzzle: new international evidence

Drawing upon the seminal study of Ang, Bekaert, and Liu [2005. “Why Stock May Disappoint?” Journal of Financial Economics 76 (3): 471–508], we incorporate disappointment aversion (DA, that is, aversion to outcomes that are worse than prior expectations) within a simple theoretical portfolio-choice model. Based on the results of this model, we then empirically address the portfolio allocation problem of an investor who chooses between a risky and a risk-free asset using international data from 19 countries. Our findings strongly support the view that DA leads investors to reduce their exposure to the stock market (i.e. DA significantly depresses the portfolio weights on equities in all cases considered). Overall, our study shows that in addition to risk aversion, DA plays an important role in explaining the equity premium puzzle around the world.     

Modeling the business risk of financially weakened firms: A new approach for corporate bond pricing

Most structural models of default risk assume that the firm's asset return is normally distributed, with a constant volatility. By contrast, this article details the properties that the process of assets should have in the case of financially weakened firms. It points out that jump-diffusion processes with time-varying volatility provide a refined and accurate perspective on the business risk dimension of default risk. Representative Arrow-Debreu state price densities (SPD) and term structures of credit spreads are then explored. The credit curves show that the business uncertainties play a major in the pricing of corporate liabilities.     

Bond pricing in a hidden Markov model of the short rate

Abstract. We consider a diffusion type model for the short rate, where the drift and diffusion parameters are modulated by an underlying Markov process. The underlying Markov process is assumed to have a stochastic differential driven by Wiener processes and a marked point process. The model for the short rate thus falls within the category of hidden Markov models.     

Exploring the components of credit risk in credit default swaps

In this paper, we test the influence of various fundamental variables on the pricing of credit default swaps. The theoretical determinants that are important for pricing credit default swaps include the risk-free rate, industry sector, credit rating, and liquidity factors. We suggest a linear regression model containing these different variables, especially focusing on liquidity factors. Unlike bond spreads which have been shown to be inversely related to liquidity (i.e., the greater the liquidity, the lower the spread), there is no a priori reason that the credit default swap spread should exhibit the same relationship. This is due to the economic characteristics of a credit default swap compared to a bond. Our empirical result shows that all the fundamental variables investigated have a significant effect on the credit default swap spread. Moreover, our findings suggest that credit default swaps that trade with greater liquidity have a wider credit default swap spread.     

Pseudo resilient supply chains: concept,traits, and practices

Supply chain vulnerability (SCV) and its counterpart supply risk management are increasingly researched in recent years. SCV is often quantifiable and can be effectively monitored if practices are implemented on a systematic basis. It is essentially more important to extend the research in supply chain risk management so as to address certain traits where the companies perform poor or areas where they overlook their performances. Here, we introduce the concept and property, the so-called pseudo resilience in supply chains where supply chains pretend to perform better in its risk management capabilities, but are essentially vulnerable. Pseudo resilience is an incessant nature of many supply chains to overlook concomitant risks. Typical traits of pseudo resilience were identified in this research and a brief analysis of the disruptions and its effects was done. This research is a maiden effort in the direction of addressing the property of pseudo resilience in supply chains. It is imperative for managers to identify the traits of pseudo resilience in their supply chains so as to avoid the ill effects resulting from it. Further quantitative and qualitative researches are recommended for evincing the property of pseudo resilience in supply chains.     

w-MPS risk aversion and the shadow CAPM: theory and empirical evidence

This paper presents the shadow capital asset pricing model (CAPM) of Ma [2011a. Advanced Asset Pricing Theory. London: Imperial College Press] as an intertemporal equilibrium asset pricing model, and tests it empirically. In contrast to the classical CAPM – a single-factor model based on a strong behavioral or distributional assumption – the shadow CAPM can be represented as a two-factor model, and only requires a modest behavioral assumption of weak form mean-preserving spread risk aversion. The empirical tests provide support in favor of the shadow CAPM over the classical CAPM, the consumption CAPM, or the Epstein and Zin [1991. “Substitution, Risk Aversion and the Temporal Behavior of Consumption and Asset Returns: An Empirical Analysis”. Journal of Political Economy 99, 263–286] model. Moreover, the shadow CAPM provides a consistent explanation for the cross-sectional variations of expected returns on the stocks and for the time-varying equity premium.     

Foreign debt supply in an imperfect international capital market: Theory and evidence

We investigate the determinants of foreign borrowing costs in a stochastically growing economy. We find that these increase with the debt-wealth ratio, depending also upon the volatilities of domestic and foreign origin, and the length of debt contract. In addition, the sensitivity of the short-term debt supply to the debt-wealth ratio exceeds that of long-term debt, and the effects of volatility on the borrowing premium, growth of wealth, and its volatility, depend on the relative size of a direct effect and a secondary portfolio-adjustment effect of the initial shock, as well as the length of the debt contract. Panel regressions suggest that the empirical evidence generally support the theoretical predictions.     

Locational effects and the cost of corporate bonds: the role of information

The public yield spreads of bonds vary widely between Chinese provinces/municipalities, with the average for the highest province double that of the lowest one. Although we find that these patterns are mainly attributable to economic and legal conditions, locational effects like geographic distance and public firm credit ratings also appear to be contributory. We show that these effects are induced by different regional informational environments and are robust to controlling for potential endogenous location choices.     

Bond market development and bank stability: Evidence from emerging markets

We investigate how bond market development shapes banks’ risk taking in terms of portfolio structure, liquidity risk, and overall bank risk. Exploiting a bank-level database of 26 emerging markets, we find that larger bond markets are associated with stronger bank liquidity positions, lower portfolio risk of banks, and higher overall stability of banks. The effect of bond market development on bank risk taking remains robust across different levels of bank size and capital sufficiency. Overall, we find new evidence of a complementary relationship between bond market development and bank soundness.     

Institutions,banking structure and the cost of debt: new international evidence

This paper analyses the effect of institutions and the structure of the banking system on the cost of debt for a sample of firms from 37 countries. The cost of debt decreases with the rule of law, the protection of creditors’ rights and the weight of banks in the economy. Bank financing and bank concentration have a positive differential effect on the cost of debt in those countries where the financial difficulties of banks are greater. Legal enforcement, the protection of creditors’ rights and the weight of bank financing have a greater influence in countries with a lower degree of economic development.     

The role of no-arbitrage on forecasting: Lessons from a parametric term structure model

Parametric term structure models have been successfully applied to numerous problems in fixed income markets, including pricing, hedging, managing risk, as well as to the study of monetary policy implications. In turn, dynamic term structure models, equipped with stronger economic structure, have been mainly adopted to price derivatives and explain empirical stylized facts. In this paper, we combine flavors of those two classes of models to test whether no-arbitrage affects forecasting. We construct cross-sectional (allowing arbitrages) and arbitrage-free versions of a parametric polynomial model to analyze how well they predict out-of-sample interest rates. Based on US Treasury yield data, we find that no-arbitrage restrictions significantly improve forecasts. Arbitrage-free versions achieve overall smaller biases and root mean square errors for most maturities and forecasting horizons. Furthermore, a decomposition of forecasts into forward-rates and holding return premia indicates that the superior performance of no-arbitrage versions is due to a better identification of bond risk premium.     

The estimation and determinants of emerging market country risk and the dynamic conditional correlation GARCH model

Country risk assessment is central to the international investment, which recently has increasingly focused on emerging markets (EM). In this paper we proxy for country risk in EM by using time-varying beta. We extend existing literature by applying a dynamic conditional correlation GARCH model. After confirming beta is time varying in twenty EM over the period January 1995 to December 2008 we investigate the GARCH (1,1) model and find the t-distribution generates the lowest forecast errors compared to the normal error distribution and a generalised error distribution. In a comparison of previous modelling techniques the results of our modified Diebold-Mariano test statistics suggest that the Kalman Filter model outperforms the GARCH model and the Schwert and Seguin (1990) model. Using a DCC-GARCH model our evidence suggests that considering dynamic betas can improve beta out-of-sample predicting ability and therefore offers potential gains for investors. Finally, we find dynamic betas across EM are strongly associated with each nation's interest rates, US interest rates and the Consumer Price Index (CPI) and to a lesser extent the exchange rates. Our results have some similarities to those in previous studies of developed markets in the economic determinants of time-varying beta but differences exist in the results on best model to forecast time-varying beta. These findings have implications for estimating country risk for investment and risk management purposes in EM.     

Sovereign debt spreads in EMU: The time-varying role of fundamentals and market distrust

This paper provides further analysis on the determinants of sovereign debt spreads for peripheral Eurozone countries since the start of EMU, paying special attention to episodes that characterized the global financial crisis aftermath starting in 2007. More specifically, the purpose of our research is to disentangle the role of fundamental variables and market perception about variations on risk in order to explain the evolution of sovereign spreads in EMU during the recent crisis. Our results, in line with previous literature, show the importance of three groups of observable variables, namely, changes in risk-aversion of creditors, fiscal indebtedness and liquidity variables. In addition, our model includes unobserved components that are estimated through the Kalman filter as time-varying deviation from fixed-mean parameters of spread determinants. This shows the importance of expectations (market sentiments), amplifying (or reducing) the relative importance of the spread determinants over time through the time-varying behavior of the parameters around their steady-state estimates.     

State ownership and the cost of debt: Evidence from corporate bond issuances in China

Corporate credit risk can be reduced through implicit government guarantees. State-owned enterprises (SOEs) in China provide a distinctive setting to investigate government roles in corporate debt financing. We find that non-SOEs’ corporate bond issuance costs are significantly higher than those of SOEs. We also observe relatively lower bond issuance costs for firms controlled by the central government (CSOEs) than those controlled by local governments (LSOEs). In addition, we demonstrate that compared with SOEs, non-SOEs’ financial constraints are mitigated to a larger extent after the bond issuances. Overall, we show that state ownership plays an important role in determining corporate bond issuance costs.     

Cross‐Border Bank M&As and Risk: Evidence from the Bond Market

The impact of cross‐border bank M&As on bank risk remains an open question. Though geographically diversifying bank M&As have the potential to reduce the risk of bank insolvency, they also have the potential to increase that risk due to the increase in risk‐taking incentives by bank managers and stockholders following these transactions. This paper empirically investigates whether cross‐border bank M&As increase or decrease the risk of acquiring banks as captured by changes in acquirers' yield spreads. This paper also investigates how differences in the institutional environments between bidder and target countries affect changes in yield spreads following M&A announcements. The study finds that bondholders, in general, perceive cross‐border bank M&As as risk‐increasing activities, unlike domestic bank mergers. Specifically, on average, yield spreads increase by 4.13 basis points following the announcement of cross‐border M&As. This study also finds that these yield spreads are significantly affected by the differences in investor‐protection and deposit insurance environments between the transacting countries. However, the study does not find that the regulatory and supervisory environment in the home countries of the transacting parties significantly affects the changes in yield spreads. The overall evidence suggests that regulators should judge the relative environment in both the home and the host countries in evaluating the associated risks of an active multinational financial institution and in setting the sufficiency of the banks' reserve positions.     

Social compliance audits and multinational corporation supply chain: evidence from a study of the rituals of social audits

This study investigates the use of social compliance audits in the supply chain of multinational corporations (MNCs). Particularly, we explore the use of such audits in assessing and managing the working conditions of factory workers in the garment industry in a developing nation. Through a range of interviews with MNCs’ internal auditors, with commissioned external auditors and with representatives of the suppliers in Bangladesh, this study finds that social compliance audits become ritual strategies and are not a primary means of advancing workers’ rights. Drawing on the concept of surrogate accountability, the study suggests that to create real change in workers’ conditions and in order to hold MNCs and their suppliers accountable, some form of surrogate (government, non-governmental organisations or media) intervention is necessary. This is, we argue, preferable to leaving it in the hands of ‘markets’ and simply waiting for another major incident such as Rana Plaza to stir public concern. This study contributes to the literature by investigating how social compliance audits are undertaken by MNCs sourcing products from a developing nation, what motivations drive the adoption of such audits, and what, if anything, are the likely outcomes from the process.     

Analyzing interest rate risk: Stochastic volatility in the term structure of government bond yields

We propose a Nelson–Siegel type interest rate term structure model where the underlying yield factors follow autoregressive processes with stochastic volatility. The factor volatilities parsimoniously capture risk inherent to the term structure and are associated with the time-varying uncertainty of the yield curve’s level, slope and curvature. Estimating the model based on US government bond yields applying Markov chain Monte Carlo techniques we find that the factor volatilities follow highly persistent processes. We show that yield factors and factor volatilities are closely related to macroeconomic state variables as well as the conditional variances thereof.     

Coupon and tax effects on new and seasoned bond yields and the measurement of the cost of debt capital

A model of the tax structure of interest rates is developed and simple approximate expressions relating yield to coupon are derived. The effect on these simple expressions of alternative assumptions about holding period length, expectations of future interest rates, and other factors, is evaluated. It is shown that with recent U.S. yield averages the new-seasoned yield spread varies with the new-seasoned coupon spread as the theory prescribes. It is concluded that new issue yield averages should provide a more reliable measure of the cost of debt capital than is provided by seasoned yield averages.     

The Co‐movement of Credit Default Swap,Bond and Stock Markets: an Empirical Analysis

We analyse the relationship between credit default swap (CDS), bond and stock markets during 2000–2002. Focusing on the intertemporal co‐movement, we examine monthly, weekly and daily lead‐lag relationships in a vector autoregressive model and the adjustment between markets caused by cointegration. First, we find that stock returns lead CDS and bond spread changes. Second, CDS spread changes Granger cause bond spread changes for a higher number of firms than vice versa. Third, the CDS market is more sensitive to the stock market than the bond market and the strength of the co‐movement increases the lower the credit quality and the larger the bond issues. Finally, the CDS market contributes more to price discovery than the bond market and this effect is stronger for US than for European firms.
