Rigid payment breaking,default spread and yields of Chinese treasury bonds

While the existence of implicit payment guarantees has long characterized Chinese bond market, recent market oriented reforms in the country have gradually broken this regime. In this context, we examine how the breaking of rigid payment regime influences the yields of Chinese treasury bonds. We argue that the rigid payment breaking affects the yields of treasury bonds by influencing investors’ setup of default risk premiums and the demand for “flight-to-quality” and “flight-to-liquidity”. Our analysis of the daily data of Chinese treasury bond transactions over the period of 2009–2019 support our theoretical arguments, indicating that rigid payment breaking has a negative impact on the yields of Chinese treasury bonds. However, this impact is heterogeneous across the bonds with different maturities and the significant effect exists only for medium and long-term treasury bonds. Our findings advance understanding of how the breaking of rigid payment regime influences the yields of financial products, providing guidelines for how investors should optimize their investment portfolios in the bond market.     

Dynamic interaction of risk–return trade-offs between oil market and China’s stock market: An analysis from the risk preferences perspective

The risk–return trade-off refers to the compensation required by investors for bearing risks, which can be viewed as the risk preference of investors in a market. The current study investigates the dynamic interdependence of risk–return trade-offs between China’s stock market and the crude oil market from the perspective of risk preference of investors, which is designed to explore the transmission process of investors’ risk preference in both markets. Specifically, this study applies the time-varying parameter GARCH-M model, namely TVP-GARCH-M model, to characterize the time-dependent risk–return trade-offs (investors’ risk preferences) in the crude oil and China’s stock markets, then examines their relationship through Granger causality tests. Results show that a variation in risk preferences of the oil market investors can dramatically cause a variation in risk preferences of the Chinese stock market investors, while the risk preference of investors in the Chinese stock market does not lead to that in the crude oil market, which is in accordance with expectations. The dynamic effect of investors’ risk appetite in the crude oil market is further examined by the TVP-VAR model. The findings of this work suggest that there generally exists a positive impact of investors’ risk preference in the oil market and that the effect is time-varying to a greater degree during the short and medium term. Moreover, responses of the Chinese stock market investors’ risk preference were more significant during the 2008 financial crisis. Additionally, the empirical results remain robust when applying alternative crude oil prices and China’s stock prices.     

Multiple equilibria in two-sector monetary economies: An interplay between preferences and the timing for money

In this paper, we study the occurrence of local indeterminacy in two-sector monetary economies. We consider a general MIUF model with two alternative timings in monetary payments: the Cash-In-Advance timing, in which the cash available to buy goods is money in the consumers’ hands after they leave the bond market but before they enter the goods market, and the Cash-After-the-Market timing, in which agents hold money for transactions after leaving the goods market. We consider three standard specifications of preferences: the additively separable formulation, the Greenwood–Hercovitz–Huffman (GHH) (Greenwood et al., 1988) formulation and the King–Plosser–Rebelo (KPR) (King et al., 1988) formulation. First, we show that for all the three types of preferences, local indeterminacy occurs under the CIA timing with a low enough interest rate elasticity of money demand. Second, we show that with the CAM timing, although determinacy always holds under separable preferences, local indeterminacy can occur with GHH and KPR preferences. We thus prove that compared to aggregate models, two-sector models provide new rooms for local indeterminacy when non-separable standard preferences are considered.     

Institutions and preferences in settings of causal complexity: foreign institutional investors and corporate restructuring practices in France

In this article, we illustrate how the interaction between institutional arrangements and the presence of different categories of firm stakeholders with specific preferences provides important insights to understand the conditions under which corporate restructuring practices are introduced. Institutions shape the range of actors' strategic options and mediate the translation of the preferences of firm stakeholders into corporate policies. Nonetheless, strategic choice remains possible since firm stakeholders constitute subgroups with different interests and incentives that influence how they operate in an institutional framework. In particular, we examine under what conditions UK/US-based institutional investors and equity-based compensation incentives are associated with the implementation of asset divestitures and employee layoffs in France. We uncover three key findings. First, the presence of hedge funds and equity-based pay influence the likelihood of French companies undertaking asset divestitures. Second, the impact of hedge funds on employee layoffs is contingent on the ownership structure of firms. Third, layoffs in France are driven by inferior performance – a result that contrasts with the American experience whereby employee layoffs are also used as a strategic mechanism to deal with institutional investors in good times. Our findings demonstrate the importance of the institutional constraints of (national level) employment protection and the moderating effects of ownership structure (firm level) on the strategic and employment policies of French companies.     

The impact of individual and institutional investor sentiment on the market price of risk

We examine the effect of individual and institutional investor sentiment on the market price of risk derived from DJIA and S&P500 index returns. Consistent with behavioral asset pricing models, we find significant positive response of rational sentiment suggesting greater incentive for rational investors to engage in arbitrage when the compensation for taking risk is greater. Further, an increase in irrational optimism leads to a significant downward movement, but an increase in rational sentiment does not lead to a significant change market price of risk. These results are robust for both market indexes, DJIA and S&P500 and for both individual and institutional investor sentiment.     

Informal investors - A categorization,with policy implications

A number of studies concerning informal investors have been carried out over the last two decades. One main conclusion from previous research has been that the informal venture capital market is very heterogeneous, and that classifications for informal investors are needed in order to more accurately depict the informal venture capital market. In this paper we propose that the market could be divided in accordance with the informal investors' investment activity and competence. The study is based on a sample of 425 active informal investors, divided into four different categories: (1) Lotto investors; (2) Traders; (3) Analytical investors; and (4) Business angels. The empirical findings show that there are considerable differences between the four categories of informal investors; differences regarding the information sources used, the level of firm involvement, co-investing, investment horizons, and geographic preferences, to name some examples. As a consequence, each of the various informal investor types responds differently to private and public prospects or motivators. It is suggested, therefore, that the informal venture capital market could be more effectively analysed and depicted by using the proposed classifications and applying differing measures to each informal investor category.     

Risk aversion for variational and multiple-prior preferences

The objective of this paper is to identify variational preferences and multiple-prior (maxmin) expected utility functions that exhibit aversion to risk under some probability measure from among the priors. Risk aversion has profound implications on agents’ choices and on market prices and allocations. Our approach to risk aversion relies on the theory of mean-independent risk of Werner (2009). We identify necessary and sufficient conditions for risk aversion of convex variational preferences and concave multiple-prior expected utilities. The conditions are stability of the cost function and of the set of probability priors, respectively, with respect to a probability measure. The two stability properties are new concepts. We show that cost functions defined by the relative entropy distance or other divergence distances have that property. Set of priors defined as cores of convex distortions of probability measures or neighborhoods in divergence distances have that property, too.     

Extracting market information from equity options with exponential Lévy processes

Lévy processes have been successfully applied in the modeling of financial assets. Useful information such as implied volatility, skewness, and risk-preferences can be derived from market option prices. In this paper, we advocate using Esscher conjugate Lévy processes to estimate risk-neutral and empirical densities. More specifically, we employ the exponential Meixner and NIG processes to calculate in closed form the pricing kernel in the equity market and then study the evolution of equity market behavior between 2002 and 2010. Our empirical analysis using S&P 500 options shows that the risk preferences of equity investors were signalling an anomaly in the market well before the subprime prime mortgage crisis (August 2007) and the crisis of confidence that followed, anticipating the downfall in equity markets in 2008, but then returning to normal levels in 2009.     

Quality Diversity and Prices in Markets for Experience Goods

We analyze vertical product differentiation in a model where a good’s quality is unobservable to customers before purchase, a continuum of quality levels is technologically feasible, and minimum quality is supplied by a competitive fringe of firms. After purchase the true quality of the good is revealed. To provide firms with incentives to actually deliver promised quality, prices must exceed unit variable costs. We show that for a large class of customer preferences there is “quality polarization,” that is, only minimum and maximum feasible quality are available in the market. For the case without quality polarization we derive sufficient conditions for the incentive constraints to completely determine equilibrium prices, regardless of demand, for all intermediate quality levels.     

Probabilistic assignments of identical indivisible objects and uniform probabilistic rules

We consider a probabilistic approach to the problem of assigning k indivisible identical objects to a set of agents with single-peaked preferences. Using the ordinal extension of preferences we characterize the class of uniform probabilistic rules by Pareto efficiency, strategy-proofness, and no-envy. We also show that in this characterization no-envy cannot be replaced by anonymity. When agents are strictly risk averse von Neumann-Morgenstern utility maximizer, then we reduce the problem of assigning k identical objects to a problem of allocating the amount k of an infinitely divisible commodity.     

Platform market competition with endogenous side decisions

This paper develops a framework to analyze platform competition in two‐sided markets in which agents endogenously decide on which side of a platform to join. We characterize the equilibrium pricing structure and perform a comparative statics analysis on how the distribution of agents’ preferences affects the platforms’ profits. We also show that the market equilibrium under profit‐maximizing platforms leads to the first best social surplus, which illustrates the importance of the price mechanism to induce more balanced participation across the two sides. This framework can be applied to analyze market competition for “rental” or “sharing” platforms. In addition, we extend our analysis to consider an initial investment stage, which makes participants the owner of some durable goods to rent out.     

The Economic Consequences of Increased Disclosure: Evidence from Cross-Listings of Chinese Firms

In this paper, we investigate the impact of cross‐listings on information asymmetry risk, the cost of capital and firm value of a group of cross‐listed Chinese companies. Our paper is the first to examine the effect of cross‐listing on information asymmetry risk. Because cross‐listed firms are subject to increased disclosure requirements, increased regulatory scrutiny and increased legal liability, we propose that Chinese cross‐listed firms have lower information asymmetry risk, lower cost of capital and higher firm value than their non‐cross‐listed counterparts. We find in both univariate and multivariate tests that cross‐listed firms enjoyed lower information asymmetry risk in the domestic market compared with the non‐cross‐listed firms. We also find that cross‐listed firms have lower cost of capital in the cross‐listing market than non‐cross‐listed firms in the domestic markets. Finally, we find that cross‐listed firms are associated with higher firm value as measured by Tobin's Q. These results have implications for international investors and companies seeking cross‐listing opportunities.     

Heterogeneous beliefs with herding behaviors and asset pricing in two goods world

We construct a incomplete information equilibrium model with heterogeneous beliefs and herding behaviors to identify their joint effects on the dynamics of asset prices. Herding behaviors make investors revise some of their estimations about expected growth rates of goods streams toward to the other one’s by a manner of weighted average of their own forecast and the other’s. As we expected, herding behaviors generate influences on the Radon Nikodym derivative, that is so-called “sentiment” as in Dumas et al. (2009), and in turn not only impact the dynamics of asset prices but also generate influences on investors’ survivals. We also show that introducing heterogeneous beliefs with herding behaviors permits to explain both the Backus–Smith puzzle and the mixed results about the influences of herding behaviors on asset prices. Moreover, we uncover that herding behaviors have positive influences on stocks’ risk premiums.

Return and Risk Premium Seasonalities in three Emerging Asian Markets: Hong Kong,Korea and Taiwan*

In this study, we find that seasonal return patterns differ from that implied by risk premiums in three emerging Asian markets; namely, Hong Kong, Korea and Taiwan. Positive January seasonal returns are found in the Hong Kong and Taiwan markets, while positive February seasonal returns are also found in Taiwan. These findings suggest that investors should place their money in these markets during January but not for the months of June and December in Korea, and for the months of May and November in Taiwan. Corporate managers should also be aware of the need to adjust for such seasonal variations when they use market data to evaluate the risk premium or required rate of return for projects in these markets. The results also show that the size effect may also be priced in some of these markets.     

Re-examining risk premiums in the Fama–French model: The role of investor sentiment

This paper reconstructs the Fama–French three-factor (F–F) model as a panel smooth transition regression (PSTR) framework to investigate the differentiated effects of investor sentiment proxies-the volatility index (VIX), credit default swap (CDS), and TED spread-on the three risk premiums. Sample period spans from 2003: 1Q to 2013: 4Q. Sample objects are 58 semiconductor companies listed on Taiwan Security Exchange Corporation. The empirical results report that stock returns display a nonlinear path, and the three risk premiums are time-varying, depending on different proxies of investor sentiment in different regimes. Market premiums fall as investors in stock markets show extreme optimism or extreme pessimism. Except in rare situations, the size premium is significant and decreases with the increase in the VIX. Returns in holding growth stocks dominate holding value stocks when the investors show extreme pessimism or optimism. However, in normal sentiment of investment, value stocks earn more returns than growth stocks.     

Portfolio choice,behavioral preferences and equity home bias

We provide a plausible explanation of aggregate portfolio behavior, in a framework where economic agents have behavioral (narrow framing) preferences. The representative agent derives utility not only from consumption (standard models) but also from risky financial wealth fluctuations. Moreover, the investor frames the stock market risk narrowly and has loss averse preferences. We numerically solve, for the foreign equity share, a simple model of international portfolio choice, providing a possible explanation for the equity home bias puzzle. Only economic agents able to process correctly information deriving from stock markets exploit the diversification opportunities provided by international financial markets.     

INFORMATION IN THE YIELD CURVE: A MACRO‐FINANCE APPROACH

We use a macro‐finance model, incorporating macroeconomic and financial factors, to study the term premium in the US bond market. Estimating the model using Bayesian techniques, we find that a single factor explains most of the variation in bond risk premiums. Furthermore, the model‐implied risk premiums account for up to 40% of the variability of one‐ and two‐year excess returns. Using the model to decompose yield spreads into an expectations and a term premium component, we find that, although this decomposition does not seem important to forecast economic activity, it is crucial to forecast inflation for most forecasting horizons.

An analytical solution for the robust investment-reinsurance strategy with general utilities

In financial markets, different investors have different attitudes or preferences on the investment policies and reinsurance problems. For investors with different investment utilities, how to provide an optimal investment strategy is not only a very hard problem, but also an urgent problem to be solved. In this paper, we derive an analytical solution for the optimal allocation problem of investment-reinsurance with general-form utility function. The general utility function allows for varying relative risk aversion coefficient, which is an important feature in finance theory. However, obtaining analytical solutions for general utility function has been difficult or impossible. The solution presented in this paper is constructed through the homotopy analysis method (HAM) and written in the form of a Taylor series expansion. The fully nonlinear Hamilton–Jacobi–Bellman (HJB) equation is decomposed into an infinite series of linear PDEs, which can be solved analytically. In the end, three examples are presented to illustrate the convergence and accuracy of the method, it also demonstrates that different risk reference investors have different investment-reinsurance strategies.
