试论商业银行适应性的货币创造

本文从商业银行在创造货币过程中的主动性与被动性入手,分析商业银行是如何创造(收缩)货币的,其适应性创造货币能力的大小,一方面取决于法定存款准备金率的高低,另一方面还取决于创造货币的成本和风险。在实践中,中、西方商业银行在不同经营方针下的适应性货币创造行为各不相同。

Can Japan or China replace the US as the monetary anchor for Hong Kong and Macau?

This contribution attempts to examine the relative importance of the US, Japan and China to Hong Kong and Macau, two effective dollar-based currency boards today, by evaluating the economic potentiality of Japan or China as an alternative monetary anchor country against the US. The assessment is made according to the criteria prescribed by the optimum currency areas (OCA) theory. In addition to that, a subsidiary analysis is done to evaluate in general the suitability of their fixed exchange rate regimes, regardless of the anchor country. Amidst the existing dollar linked arrangement and the rising dominance of China, significant evidence suggests that Japan, despite its lacklustre domestic conditions, might be at least as good a monetary anchor as the US for Hong Kong. In the meantime, China seems to be a more promising monetary anchor alternative for Macau. The features of Hong Kong and Macau also appear to broadly and endogenously support their fixed exchange rates, but not all the features of Macau, a HK-dollar-based currency board, are consistently symmetrical with those of Hong Kong.     

HIGH‐ORDER SHORT‐TIME EXPANSIONS FOR ATM OPTION PRICES OF EXPONENTIAL LÉVY MODELS

The short‐time asymptotic behavior of option prices for a variety of models with jumps has received much attention in recent years. In this work, a novel second‐order approximation for at‐the‐money (ATM) option prices is derived for a large class of exponential Lévy models with or without Brownian component. The results hereafter shed new light on the connection between both the volatility of the continuous component and the jump parameters and the behavior of ATM option prices near expiration. In the presence of a Brownian component, the second‐order term, in time‐t, is of the form , with d₂ only depending on Y, the degree of jump activity, on σ, the volatility of the continuous component, and on an additional parameter controlling the intensity of the “small” jumps (regardless of their signs). This extends the well‐known result that the leading first‐order term is . In contrast, under a pure‐jump model, the dependence on Y and on the separate intensities of negative and positive small jumps are already reflected in the leading term, which is of the form . The second‐order term is shown to be of the form and, therefore, its order of decay turns out to be independent of Y. The asymptotic behavior of the corresponding Black–Scholes implied volatilities is also addressed. Our method of proof is based on an integral representation of the option price involving the tail probability of the log‐return process under the share measure and a suitable change of probability measure under which the pure‐jump component of the log‐return process becomes a Y‐stable process. Our approach is sufficiently general to cover a wide class of Lévy processes, which satisfy the latter property and whose Lévy density can be closely approximated by a stable density near the origin. Our numerical results show that the first‐order term typically exhibits rather poor performance and that the second‐order term can significantly improve the approximation's accuracy, particularly in the absence of a Brownian component.
