We give an example of a subspace K of such that , where denotes the closure with respect to convergence in probablity. On the other hand, the cone C ≔ K − L ∞ + is dense in L ∞ with respect to the weak-star topology σ( L ∞ , L 1 ) . This example answers a question raised by I. Evstigneev. The topic is motivated by the relation of the notion of no arbitrage and the existence of martingale measures in Mathematical Finance. 相似文献

The paper uses micro‐level price data from the European car market to examine why there are deviations from the law of one price. The absolute law of one price is strongly rejected, but there is convergence to its relative version. Two sets of explanations are considered: (i) price‐setting in segmented markets, and (ii) arbitrage barriers. Overall, the determinants of arbitrage costs have more explanatory power. The single most important factor is the distance between markets. Evidence for Belgium and Luxembourg suggests that a single currency lowers price differences significantly. 相似文献

We examine the industrial organization and institutional development of the asset management industry in Asian developing economies—specifically in China, Indonesia, Korea, Malaysia, Singapore, Philippines, and Thailand. We focus on the size and growth of the buy‐side of the respective financial markets, asset allocation, the regulatory environment, and the state of internationalization of the fund management industry in its key components—mutual funds, pension funds, and asset management for high net worth individuals. We link the evolution of professional asset management in these environments to the development of the respective capital markets and to the evolution of corporate governance. We find that the fund management industry occupies a very small niche in domestic financial systems that are dominated by banks. At the same time, we find that its growth has been very rapid in the early 2000s and we suggest that this is likely to persist as the demand for professional management of financial wealth in the region develops and as the pension fund sectors of the respective economies are liberalized to allow larger portions of assets to be invested in collective investment schemes. 相似文献

In this paper we attempt to describe both the data sources and organizational methods that allow for effective and easily created SAMs and regional computable general equilibrium (CGE) models. Small cities of around 100,000 people will face very different constraints than a town of 2000 people. Unfortunately, most CGE models typically describe relatively large geographical areas and are therefore not able to capture the uniqueness of individual cities within the region. An illustrative example using these methods demonstrates that the economic impacts vary substantially over different municipalities to the same economic shock. 相似文献

The automotive industry is undergoing a strategic transition. Cost pressure from rising stock levels in the market and increasing incentives needed to sell these vehicles are forcing vehicle manufacturers to rethink their prevalent “stock‐push” approach, building vehicles against a forecast and selling from stock, in favor of a stock‐less “build‐to‐order” order fulfillment strategy. More responsive order fulfillment at the vehicle manufacturer level however will not only require flexible and responsive component supply, but will also have wide ramifications for the logistics operations. Based on three case studies of major inbound logistics operations, this exploratory study assesses their ability to support such a build‐to‐order approach, as well as the potential implications of such transition. The paper concludes with a set of general strategies for how these implications could be mitigated. 相似文献
