联合确定基数合约:对魏茨曼模型的一个改进

本文针对国内外委托代理理论主要局限于理论分析层面而实用性不强的特点,在概要评论有关利润基数确定的相关文献的基础上,通过对美国一家公司委托代理实际案例的研究,提出了旨在能够解决实际委托代理关系的"联合确定基数法"。文章分析了联合确定基数法与棘轮效应模型的区别和联系,以数学方法论证了联合确定基数法的若干命题,描述了公司利润基数确定的利益诱导机制,并对比分析了联合确定基数法与西方教科书中的"激励设计模型"。本文试图以联合确定基数法为核心内容的一次性动态模型,代替蕴含着讨价还价过程的多次性动态模型。     

Asymmetric wealth gains in joint ventures: Theory and evidence

I examine the causes of asymmetric wealth gains (instances where one partner gains and the other partner loses) and the extent of these gains in joint ventures. I argue that asymmetric gains arise as the common benefits created by the venture are offset by the negative wealth effects of resource appropriation for one parent. Using a sample of 412 joint ventures I find that in 42% of the ventures one parent gained and the other lost. In addition, I find that when the abnormal returns of parents within a venture were compared, firms that gained more from forming the venture experienced [−1,0] returns of +3.22% and firms that gained less experienced [−1,0] returns of −1.37%. Additional analyses showed that asymmetric wealth gains tended to occur in ventures where one parent had relatively high valued resources and the other parent had relatively lower valued resources thus suggesting that resource appropriation may be an important cause of this pattern of gains.     

Sales channel integration after mergers and acquisitions: A methodological approach for avoiding common pitfalls

This article addresses the integration of sales channels after mergers and acquisitions (M&A) by appraising the strengths, weaknesses, and biases associated with the four most common frameworks for evaluating sales channels (sales management, historical performance, strategic fit, and customer choice) for their appropriateness in a post-M&A context. The authors develop a methodological approach that uses a balanced-scorecard framework to guide managers through the sales channel integration process, and then apply this approach to the merger of two industrial firms' sales organizations across 21 territories. In so doing, they reveal various pitfalls and propose and test some analytical corrections. Longitudinal performance data support comparisons across the different evaluative frameworks; in particular, the sales management and customer choice frameworks provide the most insight into channel partners' post-integration performance. The results support the premise that channel integration can be improved by accounting for factors unique to the M&A context and using an approach that triangulates multiple perspectives.     

Speculative attacks to currency target zones: A market microstructure approach

This paper develops a simple optimization model to characterize the behaviour of market participants during currency attacks and tests it empirically. Specifically, we test for the determinants of the timing, magnitude and chance of success of an attack. The empirical part is carried out using Mexican data, as this market provides us with an appropriate target zone framework and with a very rich dataset. We find empirical support for a set of microeconomic determinants which include: daily order flow, inventory management, intra-day price volatility, and the forward intervention-price differential. Finally, we test for the role of central bank reserves in speculative attack dynamics.     

Regime-switching and interest rates in the European monetary system

This paper examines the impact that a currency target zone has on short-term interest rates. For a number of countries in the European Monetary System, we characterize the short rate using a regime-switching model that allows for a differently parameterized mean-reverting square-root process in each regime. We find that the volatility, the level, and the speed-of-adjustment are all higher in the regime that is operative during speculative attacks and currency crises. Moreover, we allow the conditional probability of being in each regime to be state-dependent so the model can be used to examine questions relating to the likelihood of realignments and the stability of the target zone system.

Human resources in Sino-foreign joint ventures: selected case studies in Shanghai,compared with Beijing

This article examines HRM in joint ventures (JVs) in Shanghai compared with those in Beijing using a case-study approach. It focuses primarily on issues relating to labour contracts, rewards and benefits, social insurance, trade unions and personnel policies, and describes current developments in China in each of these areas. In order to place these JV human resource practices in context, we also draw on interviews in state-owned enterprises (SOEs) in Shanghai and Beijing. Taking as a starting point a summary of traditional SOE 'iron rice-bowl' ( tie fan wan ) practices in the management of personnel, we ask to what extent HRM in the present JV sample differs from traditional methods and to what extent 'iron rice-bowl' practices continue despite foreign ownership. The extent to which HR practices in JVs are distinct from those in contemporary SOEs is also examined. We conclude that, although, as one would expect, foreign ownership has modified traditional practice, the degree and extent to which this is true varies widely. There is strong evidence of institutional and organizational continuity in 'iron rice-bowl' practices in both JVs and SOEs. Finally we propose a framework for categorizing the companies investigated in terms of their distance from traditional 'iron rice-bowl' HR practices and proximity to 'imported' practices. This consists of two 'pure' and two hybrid categories: pure 'iron rice-bowl'; hybrid I (predominantly local); hybrid II (predominantly imported): and, finally, pure imported. In this schema, the companies examined do not however group neatly according to whether they are JVs or SOEs.     

Multi-cultural leadership teams and organizational identification in international joint ventures

Many international joint ventures (IJVs) fare poorly. An important factor is that members of an IJV top management team (TMT), which generally comprises people from different cultures, often find it difficult to work together. In this paper we argue that social identity theory and organizational identification processes can help us understand why this is so. We propose that factionalism in a TMT is a significant hazard posed by member identification with different parents. In addition, identification with both the IJV and a parent firm can lead to significant role conflict for IJV top managers. Factionalism and role conflict in turn can result in poor intra-TMT communications and inefficient decision making. Literature in social identity theory and organizational identification suggests that the relative status and power of parents as well as successes of IJVs can affect TMT members' identification with the IJV or the parent company. Preliminary field interviews provide general support for these propositions. Our analysis suggests that organizational identity and identification can be a valuable tool to facilitate the understanding of TMT functioning and IJV performance.
