Renminbi Going Global

The present paper evaluates the international status of the Chinese currency, the renminbi (RMB), by examining its use in the global market. Specifically, the discussion focuses on the recent developments of RMB trading in the global foreign exchange market, cross‐border trade settlement in RMB, the Hong Kong offshore market and China's policies relating to the RMB. The evidence suggests that the use of the RMB overseas, especially in trade financing and in the off‐shore market, has increased rapidly in recent years. However, compared with the size of the Chinese economy, the current scale of the use of the RMB is quite small. Although the RMB has great potential to become an international currency, its acceptance in the global economy is affected by both economic and political factors. Attaining a fully fledged international RMB is still a distant goal.     

European asset swap spreads and the credit crisis

We examine time-varying behaviour and determinants of asset swap (ASW) spreads for 23 iBoxx European corporate bond indexes from January 2006 to January 2009. The results of a Markov switching model suggest that ASW spreads exhibit regime-dependent behaviour. The evidence is particularly strong for Financial and Corporates Subordinated indexes. Stock market volatility determines ASW spread changes in turbulent periods, whereas stock returns tend to affect spread changes in calm periods. While market liquidity affects spreads only in turbulent regimes the level of interest rates is an important determinant of spread changes in both regimes. Finally, we identify stock returns, lagged ASW spread levels, and lagged volatility of ASW spreads as major drivers of the regime shifts. The results are robust in the extended sample (January 2006 to October 2013) that includes a post-crisis period.     

Does gold offer a better protection against losses in sovereign debt bonds than other metals?

It is a commonly held view that gold protects investors’ wealth in the event of negative economic conditions. In this study, we test whether other metals offer similar or better investment opportunities in periods of market turmoil. Using a sample of 13 sovereign bonds, we show that other precious metals, palladium in particular, offer investors greater compensation for their bond market losses than gold. We also find that industrial metals, especially copper, tend to outperform gold and other precious metals as hedging vehicles and safe haven assets against losses in sovereign bonds. However, the outcome of the hedge and safe haven properties is not always consistent across the different bonds. Finally, our analysis suggests that copper is the best performing metal in the period immediately after negative bond price shocks.     

The Effect of Corporate Social Responsibility on Cost of Corporate Bond: Evidence from China

This article examines the link between corporate social responsibility(CSR) and cost of bond(COB) in China. We find that there exists a negative relationship between CSR and COB. In particular, when the bond issuer is a state-owned enterprise, or when the credit rating of bond is high, the negative association between CSR and COB is strengthened. The findings indicate that CSR plays a significant role in reducing the risk premium of corporate bonds through an insurance-like effect. Moreover, the effect of CSR on COB also depends on contextual factors such as firm ownership and bond credit rating.     

Contingent capital conversion under dual asset and equity jump–diffusions

We model contingent capital with market trigger under dual jump–diffusion processes in asset values and equity prices. Under the dual jump–diffusions, we show that the conversion ratio is no longer deterministic under the jump–diffusion. The conversion ratio becomes a stochastic process related to the jump process of the underlying equity and the conditional expectation of the contingent capital at the conversion time. Thus, making the implementation of contingent capital impossible. The best we can hope to practically implement this conversion design, is to give the minimal conversion ratio (at least the portion required to convert) to conform with Basel III.     

How much can illiquidity affect corporate debt yield spread?

We present a structural method for measuring the upper bound for the illiquidity risk of liabilities issued by a levered firm. The method calculates the upper bound of illiquidity spread of a corporate bond given its duration and the issuing firm’s asset risk and leverage ratio. Consistent with the empirical literature the illiquidity spread is positively related to the issuing firm’s asset risk and leverage ratio and the illiquidity component increases with a bond’s credit quality. The term structure of illiquidity spread has a humped shape, where its maximum level depends on the firm’s leverage ratio. Finally, we demonstrate how the method’s implied restricted trading period can be used as a measure for illiquidity in the bonds’ market.     

The cross section of international government bond returns

Volatility risk, credit risk, value effect, and momentum are major return drivers in the fixed-income universe. This study offers a four-factor pricing model for international government bonds. The model thoroughly explains the variation of government bond returns and covers a range of more than 60 cross-sectional return patterns in government bond markets, verifying its usefulness for asset pricing. The research was conducted within a sample of bonds from 25 developed and emerging markets for the years 1992 to 2016.     

Co-Production and Value Co-Creation in Outcome-Based Contracting in Public Services

This paper contributes to theorizing and analysing different processes of co-production and value co-creation within outcome-based contracting (OBC). It investigates how different OBC mechanisms are implemented in practice, and with what implications for public service users’ experiences and outcomes. Using realist synthesis techniques, the paper analyses existing evaluations that focus on users’ experiences of OBC in welfare-to-work services and a homelessness project. It highlights how OBC can affect equality, effectiveness and innovation within public services. The paper also exemplifies the importance of analysing how the political and policy context of public services affects both service pathways and their outcomes.
