Despite an extensive market segmentation literature, applied academic studies which bridge segmentation theory and practice remain a priority for researchers. The need for studies which examine the segmentation implementation barriers faced by organisations is particularly acute. We explore segmentation implementation through the eyes of a European utilities business, by following its progress through a major segmentation project. The study reveals the character and impact of implementation barriers occurring at different stages in the segmentation process. By classifying the barriers, we develop implementation "rules" for practitioners which are designed to minimise their occurrence and impact. We further contribute to the literature by developing a deeper understanding of the mechanisms through which these implementation rules can be applied.

Using Triad-based multinational enterprises as their empirical setting, influential scholars in international management uncovered key organizational characteristics needed to create globally integrated and locally responsive multinationals. They proposed a “modern” theory of multinationals' organization (Hedlund, 1994). But recently, a new generation of multinationals from emerging markets has appeared. Little is known about their organizational choices and some scholars even doubt that they leverage organizational capabilities altogether. Does the “modern” theory still hold in their case? This exploratory study of three emerging-market multinationals (EMNEs) discloses that for reasons related to their origin in emerging economies and to the competitive specificities of these economies, EMNEs approach the global and local conundrum in ways which are both similar – and vastly different – from recommendations of the “modern” theory. We inductively develop a new theory that accounts for the evolution of organizational capabilities in EMNEs to reconcile global integration and local responsiveness. We discuss its implications for the executives of both emerging and Triad-based multinationals.

This paper examines the determinants of cross-platform arbitrage profits. We develop a structural model that enables us to decompose the likelihood of an arbitrage opportunity into three distinct factors: the fixed cost to trade the opportunity, the level at which one of the platforms delays a price update and the impact of the order flow on the quoted prices (inventory and asymmetric information effects). We then investigate the predictions from the theoretical model for the European Bond market with the estimation of a probit model. Our main finding is that the results found in the empirical part corroborate strongly the predictions from the structural model. The event of a cross market arbitrage opportunity has a certain degree of predictability where an optimal ex ante scenario is represented by a low level of spreads on both platforms, a time of the day close to the end of trading hours and a high volume of trade.

The Indigenous art market plays a significant role both in promoting appreciation for the accomplishments of Aboriginal culture and within broader concepts of the export of a national culture.[1] Despite the growth in status and impact of Indigenous art over the past decade, very little scholarship or resources exist to assist their development and analyse their impact on economic or social wellbeing. This paper canvasses new ways of operating the Indigenous art market to better support emerging and established artists in a globalised economy and suggests that there is a pressing need for future research to develop a new framework for its operation.

This study revisits the capital structure theory and test Pecking Order Hypothesis (POH) and Static Order Trade-off theory (STOT) using Malaysian Listed firms over a period from 1999 to 2002. The evidence from pecking order model suggests that the internal fund deficiency is the most important determinant that possibly explains the issuance of new debt in Malaysian capital market despite the lower predicting power.  While static trade off-model is not fit to explain the issuance of new debt issue in Malaysian capital market. This is an interesting findings that confirm the fact that Malaysian firms do not too much care about tax-shield benefit derive from employ both debt and non-debt tax-shield. The finn's size, which is used to neutralize the size effect, appears to provide some explanation for the variation in its capital structure policy choice; however asset structure and growth no evidence of static-order-trade-off is observed in Malaysian capital market.

An essential function of derivative markets is price discovery. A model is proposed to incorporate a comprehensive dynamic interaction between price size coordinates of orders and trades. An example of application of the model and its effect on price discovery is discussed.

Most empirical evidence suggests that the efficient futures market hypothesis, henceforth referred to as EFMH, stating that spot and futures prices should cointegrate with a unit slope on futures prices, does not hold, a finding at odds with many theoretical models. This article argues that these results can be attributed in part to the low power of univariate tests, and that the use of panel data can generate more powerful tests. The current article can be seen as a step in this direction. In particular, a newly developed factor analytical approach is employed, which is very general and, in addition, free of the otherwise so common incidental parameters bias in the presence of fixed effects. The approach is applied to a large panel covering 17 commodities between March 1991 and August 2012. The evidence suggests that the EFMH cannot be rejected once the panel evidence has been taken into account. © 2014 Wiley Periodicals, Inc.

Purpose– This paper aims to explore the issue of corporate governance mechanisms by including the importance of stakeholders, primary objectives of the firm and the ownership of top financial managers of listed firms in Kuwait in the survey tool. It attempts to investigate whether theory aligns with the behaviour of financial managers in practice in an emerging market case.Design/methodology/approach– A survey was developed to focus primarily on the current corporate finance practices implemented by CFOs in listed companies in Kuwait. The target respondents are listed firms in the Kuwaiti Stock Exchange (KSE). The survey includes questions on topics that are closely related to capital budgeting, capital structure, cost of capital and dividend policy. For example, the survey asks the managers how they estimate their cost of equity (CAPM or other methods) and whether the impact of the weighted average cost of equity is taken into consideration in their capital structure choices.Findings– A surprising number of firms are now widely using IRR for decision making. CAPM is also in use, whereas WACC remains the most popular method used. There is some support for the “bird‐in‐hand” dividend theory in the tax‐free environment. Firms in Kuwait do not have any particular source of capital structure choices when it comes to how best to finance their projects as is the case in the US market. Firms in Kuwait are consciously striving for maximizing profits and those managers are regarded as their most important stakeholders. This may indicate the existence of agency problems.Research limitations/implications– The limitation of this study lies in the absence of empirical investigation on how corporate finance decisions may affect firms' performance in Kuwait. Hence, empirical validation will be performed by the authors in the next stage of this research, which will form the basis for further research. Empirical validation for the impact of corporate governance on performance is needed.Practical implications– This research may benefit managers and decision makers in many aspects, including having an understanding of applying popular and the most suitable corporate finance and corporate governance techniques in the management of their companies. In this research, the authors have identified the gap between practice and academia.Originality/value– To the best of the authors' knowledge, this is the first study to examine comprehensively major areas of financial policies and practices and corporate governance in an emerging market case, especially in the Middle East. Kuwait provides a unique institutional setting in its taxation system. Therefore, this study will make a contribution to the general literature in this field.

We develop a framework to explain the private capital flows between the rest of the world and an emerging economy. The model, based on the monetary premium theory, relates an endogenous supply of foreign capitals to an endogenous differential of interest rates; its estimation uses the econometric techniques initiated by Heckman. Four questions regarding the capital flows phenomenon are explored, including the statistical process that governs the events of default and the impact of the probability of default on the interest rate differential. Using the methodology, we analyse the dynamics of foreign capital movements in Brazil during the 1991- 1998 period.

This thesis is focused on the financial model for interest rates called the LIBOR Market Model. In the appendixes, we provide the necessary mathematical theory. In the inner chapters, firstly, we define the main interest rates and financial instruments concerning with the interest rate models, then, we set the LIBOR market model, demonstrate its existence, derive the dynamics of forward LIBOR rates and justify the pricing of caps according to the Black’s formula. Then, we also present the Swap Market Model, which models the forward swap rates instead of the LIBOR ones. Even this model is justified by a theoretical demonstration and the resulting formula to price the swaptions coincides with the Black’s one. However, the two models are not compatible from a theoretical point. Therefore, we derive various analytical approximating formulae to price the swaptions in the LIBOR market model and we explain how to perform a Monte Carlo simulation. Finally, we present the calibration of the LIBOR market model to the markets of both caps and swaptions, together with various examples of application to the historical correlation matrix and the cascade calibration of the forward volatilities to the matrix of implied swaption volatilities provided by the market.

dall'avvento della liberalizzazione, aeroporti e vettori hanno vissuto cambiamenti. Il maggior miglioramneto nella gestione degli aeroporti è una gestione più commerciale ed efficiente. Le forme di regolazione economica e le caratteristiche della gestione manageriale sono state indagate. Dodici paesi sono stati scelti per indagare la situazione del trasporto aereo mondiale, fra questi sia paesi con un sistema maturo sia paesi emergenti. La distribuzione del traffico è stata analizzata con l'indice HHI per evidenziare aeroporti con concentrazione maggiore di 0,25 (in accordo con la normativa statunitense); il sistema aeroportuale è stato analizzato con l'indice di Gini e con l'indice di dominanza. Infine, la teoria dei giochi si è dimostrata un valido supporto per studiare il mercato del trasporto aereo anche con l'uso di giochi di tipo DP
