What Prompts the People＇s Bank of China to Change Its Monetary Policy Stance？ Evidence from a Discrete Choice Model

In the present paper, we model the policy stance of the People＇s Bank of China （PBC） as a latent variable, and the discrete changes in the reserve requirement ratio, policy interest rates, and the scale of open market operations are taken as signals of movement of this latent variable. We run a discrete choice regression that relates these observed indicators of policy stance to major trends of macroeconomic and financial developments, which are represented by common factors extracted from a large number of variables. The predicted value of the estimated model can then be interpreted as the implicit policy stance of the PBC. In a second step, we estimate how much of the variation in the PBC＇ s implicit stance can be explained by measures of its policy objectives on inflation, growth and financial stability. We find that deviations of CPI inflation from an implicit target and deviations of broad money growth from the announced targets, but not output gaps, figure significantly in the PBC＇s policy changes.     

American Parisian options

In this article, we describe the various sorts of American Parisian options and propose valuation formulae. Although there is no closed-form valuation for these products in the non-perpetual case, we have been able to reformulate their price as a function of the exercise frontier. In the perpetual case, closed-form solutions or approximations are obtained by relying on excursion theory. We derive the Laplace transform of the first instant Brownian motion reaches a positive level or, without interruption, spends a given amount of time below zero. We perform a detailed comparison of perpetual standard, barrier and Parisian options.     

Learning from peers' stock prices and corporate investment

Peers' valuation matters for firms' investment: a one standard deviation increase in peers' valuation is associated with a 5.9% increase in corporate investment. This association is stronger when a firm's stock price informativeness is lower or when its managers appear less informed. Also, the sensitivity of a firm's investment to its stock price is lower when its peers' stock price informativeness is higher or when demands for its products and its peers' products are more correlated. Furthermore, the sensitivity of firms' investment to their peers' valuation drops significantly after going public. These findings are uniquely predicted by a model in which managers learn information from their peers' valuation.     

Engineering Hedonic Attributes to Generate Perceptions of Luxury: Consumer Perception of an Everyday Sound

For the last twenty years, the perception of hedonic attributes has been a problematic matter in consumer research. We argue that the perception of a hedonic product attribute should not be considered as an irreducible holistic experience, but rather as a complex set of sensory experiences, the components of which are identifiable and quantifiable. We provide evidence for this position by proposing a reliable method linking the features of product-related sound stimuli to consumer perception of hedonic attributes. To our knowledge, this study is the first of its kind offering a detailed investigation of consumer perception of everyday sounds (as opposed to music). We discuss managerial and consumer-level implications of the findings and provide an agenda for future research.     

Liquidity and Arbitrage in Options Markets: A Survival Analysis Approach

This paper examines the determinants of the time it takes foran index options market to return to no arbitrage values afterput-call parity deviations, using intraday transactions datafrom the French index options market. We employ survival analysisto characterize how limits to arbitrage influence the expectedduration of arbitrage deviations. After controlling for conventionallimits to arbitrage, we show that liquidity-linked variablesare associated with a faster reversion of arbitrage profits.The introduction of an Exchange Traded Fund also affects thesurvival rates of deviations, but this impact essentially stemsfrom the reduction in the level of potential arbitrage profits.     

Central bank interventions and jumps in double long memory models of daily exchange rates

In this paper, we estimate ARFIMA–FIGARCH models for the major exchange rates (against the US dollar) which have been subject to direct central bank interventions in the last decades. We show that the normality assumption is not adequate due to the occurrence of volatility outliers and its rejection is related to these interventions. Consequently, we rely on a normal mixture distribution that allows for endogenously determined jumps in the process governing the exchange rate dynamics. This distribution performs rather well and is found to be important for the estimation of the persistence of volatility shocks. Introducing a time-varying jump probability associated to central bank interventions, we find that the central bank interventions, conducted in either a coordinated or unilateral way, induce a jump in the process and tend to increase exchange rate volatility.     

Robust estimation of intraweek periodicity in volatility and jump detection

Opening, lunch and closing of financial markets induce a periodic component in the volatility of high-frequency returns. We show that price jumps cause a large bias in the classical periodicity estimators and propose robust alternatives. We find that accounting for periodicity greatly improves the accuracy of intraday jump detection methods. It increases the power to detect the relatively small jumps occurring at times for which volatility is periodically low and reduces the number of spurious jump detections at times of periodically high volatility. We use the series of detected jumps to estimate robustly the long memory parameter of the squared EUR/USD, GBP/USD and YEN/USD returns.     

Nonlinear pricing and exclusion: I. buyer opportunism

We study the exclusionary properties of nonlinear price‐quantity schedules in an Aghion‐Bolton style model with elastic demand and product differentiation. We distinguish three regimes, depending on whether and how the price charged by the dominant firm depends on the quantity purchased from the rival firm. We find that the supply of rival good is distorted downward. Moreover, given the quantity supplied from the rival, the buyer may opportunistically purchase inefficiently many units from the dominant firm to pocket quantity rebates. We show that the possibility for the buyer to dispose of unconsumed units attenuates the opportunism problem and limits the exclusionary effects of nonlinear pricing.     

Bond offerings in China

This study appraises the value created by a bond offering in China, where high levels of state ownership and insider ownership raise concerns about the use of the proceeds. To estimate the impact of a bond issue on the firm's value, we apply an event‐study methodology on a sample of 481 issues of 347 Chinese companies over the period 2009–2013. It turns out that state ownership has a positive impact on the value of a bond offering for shareholders, which is consistent with an implicit guarantee of the issue by the state. For privately owned companies, insider ownership exerts a nonlinear impact on the firm's value, supporting an aligning effect in the use of the proceeds. Overall, the study confirms the key role of ownership structure in Chinese firms.
