Small dimension PDE for discrete Asian options 总被引:1,自引:0,他引:1
This paper presents an efficient method for pricing discrete Asian options in presence of smile and non-proportional dividends. Using an homogeneity property, we show how to reduce an n0 dimensional problem to a one- or two-dimensional one. We examine different numerical specifications of our dimension reduced PDE using a Crank–Nicholson method (interpolation method, grid boundaries, time and space steps) as well as the extension to the case of non-proportional discrete dividends, using a jump condition. We benchmark our results with Quasi Monte-Carlo simulation and a multi-dimensional PDE 相似文献

This article investigates both the marketing and the production activities of a multinational enterprise (MNE) operating in the Brazilian chemical industry. The case chosen illustrates how the MNE has managed to adapt or to upgrade some of its main policies, programs, production activities, and products in conformity with both its long-term strategic positioning and the host country's environmental regulatory policy. The company established two effective environmental programs that deserve mention. One of the programs has been set up to generate receipts through the provision of environmental services for a price. The other one pursued systematic procedures to better serve clients through customized applications of waste reduction practices. The latter reveals how proactive companies may profit from effectively envisaging the whole product cycle along their value chain. © 1995 John Wiley & Sons, Inc. 相似文献

This paper shows that abnormal stock price returns around the date of open market repurchase announcements are four times higher in Germany than in the USA (12 ver. 3%). We hypothesize that this observation can be explained by national differences in repurchase regulations. Our empirical evidence indicates that German managers primarily buy back shares to signal an undervaluation of their firm. We demonstrate that the stringent repurchase process prescribed by German law attributes a higher credibility to undervaluation signals than do the lax US regulations, and thereby corroborates our hypothesis.Financial support from the E-Finance Lab, Frankfurt am Main, and from Freitag & Co., Frankfurt am Main, is gratefully acknowledged.

We examine the stock price reactions of four Swiss banks to negotiations between Switzerland and the European Union and between
Switzerland and the United States to (i) obtain an estimate of the value of banking secrecy to Swiss banks, and (ii) distinguish
between tax evasion and genuine privacy concerns as sources of that value. We find that the value of banking secrecy to the
private banks is large, accounting for 8 to 14% of their market value; in contrast, the value of banking secrecy to the universal
banks is small. We further find that tax evasion may be less important and privacy concerns more important a source of value
of banking secrecy than might previously have been thought. 相似文献

Regulation (EU) 2015/848 (Recast European Insolvency Regulation/Recast EIR) contains a set of articles dedicated to the insolvency proceedings relative to members of groups of companies. No substantial consolidation or any procedural nature is envisaged. Article 2(13) of Regulation 2015/848 clarifies that, for the purposes of the same, a “group of companies” must be understood as “a parent undertaking and all its subsidiary undertakings.” However, many doubts arise when one goes deeper into that definition. The author deals with some of those problems and gives some suggestions to overcome them. 相似文献

This paper studies how automation impacts the structure of decision-making in organizations. We develop a theoretical model of a firm, where a principal makes a decision about how much to prioritize the new product development division when the division is led by a manager who holds private information specific to this division and has misaligned preferences with the principal. The principal chooses whether to decentralize this decision by delegating it to the manager, resulting in more informed but unbiased decision. In this setting, we investigate how automation which reduces operational variability may alter this choice of organizational structure. The findings from our analysis show that firms deploy automation resources differently depending on their organizational structure: centralized firms choose to automate divisions that face more uncertainty, while decentralized firms do the opposite. Moreover, increasing access to automation results in higher centralization of decision-making in firms. In the extensions, we show that the strategic use of automation reduces the informativeness of intrafirm communication, and also, that automation can be a strategic substitute to monetary contracts. 相似文献

This paper develops a firm‐level measure of myopic market pricing, which captures the extent to which the market overvalues short‐term expected abnormal earnings relative to longer‐term ones. The empirical analysis shows that myopically priced firms manage earnings more actively and invest less in R&D. The impact of myopic market pricing is concentrated in firms where managers cater more to market pricing, that is, in firms with greater short‐term investor ownership, with CEO compensation that is more sensitive to the firm share price, and with higher equity dependence. Additional tests show that these findings are robust to the consideration of market (under)overpricing. The results suggest that when managers cater to market pricing, market myopia encourages managerial myopia. 相似文献

A continuous model for supply planning of assembly systems with stochastic component procurement times 总被引:1,自引:1,他引:0

This paper studies a customized product assembly scenario where some components cannot be stocked due to high component cost and risk. We consider the case where these key components are ordered after a demand has been registered with a promised delivery date. Component lead-times are stochastic and associated distribution function is known in advance. The objective is to determine the ordering time for each component such as to minimize the sum of expected holding and backlogging costs. An approach to solve this problem is proposed and the algorithm is tested on a randomly generated data set. 相似文献

AbstractThis article examines the impact of the British expatriate entrepreneur, and his processes of knowledge transfer, on the industrialization and economic development of Brazil between 1875 and 1914. It focuses on the textiles industry, and combines original trademark data with conventional trade and investment statistics, and also case study analysis about firms and their entrepreneurs. It argues that British investment in Brazil was higher and had a deeper impact on economic development than considered by existing research, as expatriate entrepreneurs ‘disguised’ a substantial amount of foreign investments by acting as shareholders and top managers of newly established local businesses. 相似文献
