We study the equilibrium accounting and transfer pricing policies in a multinational duopoly with price competition in the final product market. We find that the firms in a duopoly can benefit from strategically using the same transfer price for tax and managerial purposes instead of using separate transfer prices for both objectives. According to our results, the practice of one set of books should be the prevalent accounting method in markets with a small number of competitors and similar products.  相似文献

This paper proposes a class of locally stationary diffusion processes. The model has a time varying but locally linear drift and a volatility coefficient that is allowed to vary over time and space. The model is semiparametric because we allow these functions to be unknown and the innovation process is parametrically specified, indeed completely known. We propose estimators of all the unknown quantities based on long span data. Our estimation method makes use of the property of local stationarity. We establish asymptotic theory for the proposed estimators as the time span increases, so we do not rely on infill asymptotics. We apply this method to interest rate data to illustrate the validity of our model. Finally, we present a simulation study to provide the finite-sample performance of the proposed estimators.  相似文献

A sizeable percentage of investors are using social media to obtain information about companies (Cogent Research [2008]). As a consequence, social media content about firms may have an impact on stock prices (Hachman [2011]). Various studies utilize social media content to forecast stock market-related factors such as returns, volatility, or trading volume. The objective of this article is to investigate whether a bidirectional intraday relationship between stock returns and volatility and tweets exists. The study analyzed 150,180 minute-by-minute stock price and tweet data for the 30 stocks in the Dow Jones Industrial Average over a random 13-day interval from June 2 to June 18, 2014 using a BEKK-MVGARCH methodology. Findings indicate that 87% of stock returns are influenced by lagged innovations of the tweets data, but there is little evidence to support that the direction is reciprocal, with only 7% of tweets being influenced by lagged innovations of the stock returns. Results further show that the lagged innovations from 40 percent of stock returns affect the current conditional volatility of the tweets, while 73 percent of tweets affect the current conditional volatility of stock returns. Moreover, there is strong evidence to suggest that the volatility originating from the returns to the tweets persists for 33 percent of stocks; the volatility originating from the tweets to the returns persists for 73 percent of stocks. Last, 53 percent of stocks exhibit both immediate and persistent impacts from returns to tweets, while 90 percent of stocks exhibit both immediate and persistent impacts from tweets to returns. These results may help traders achieve superior returns by buying and selling individual stocks or options. Also, asset and mutual fund managers may benefit by developing a social media strategy.  相似文献

We develop and empirically test a model of expatriate managers' work adjustment. In this model we relate the fit between work-related abilities and needs of expatriate managers as well as the fit between the job requirements of, and incentives associated with, an international assignment to the level of expatriate managers' work adjustment. We test this model with data gathered by means of an electronic survey among 118 German expatriate managers. The empirical findings largely support our theoretical model. The paper enhances our understanding of expatriate managers' work adjustment and its antecedents and contributes to the theoretical and empirical basis of research into expatriate management.  相似文献

Among the numerous factors that influence decisions on prices, consumer behaviour has special significance. This paper reviews and analyses relevant studies conducted during the last few decades. On the basis of our analysis, four categories of factors that determine consumer behaviour have been identified. Additionally, we have developed an experimental research design to analyse the influence that the following factors have on price perception: price structure (i.e. price level, order of presentation and price differences), purchase context (i.e. reason for purchase or product use) and demographic characteristics (i.e. gender). Results reveal a significant influence of these variables on consumer behaviour.  相似文献

We present three scenarios concerning access to documents in three real world fields of application, which have in common that they are very difficult to support with classical anticipative access control systems. We show, how - based on a highly configurable notification and negotiation service, which is tightly integrated with a classical access control system - the common permission and denial options can be extended with awareness and negotiation and how this approach supports the three initial access scenarios. We also introduce our implementation of the notification and negotiation service in the PoliTeam project.  相似文献

Intervention analysis is proposed as a method for estimating the effects of anti-dumping actions in the presence of a domestic cartel. Data requirements and modelling effort compare favourably with traditional structural model approaches. The method is applied to an anti-dumping action brought to the European Commission and in which the European producers of the product were fined after an anti-cartel action by the Commission covering an overlapping period. Interven tion analysis is applied to distinguish the effects of the anti-dumping action from those of changes in cartel behaviour  相似文献
