The Spatial Mobility of Corporate Knowledge: Expatriation, Global Talent, and the World City
Expatriation, and other forms of transnational labor mobility within and between firms, is a crucial organizational strategy for the spatial mobility of knowledge in the world economy. For firms, transnational mobility is a process that stretches tacit and codified knowledge across time and space, and allows them to deliver specialist know-how, skills, expertise, and outside experience to subsidiaries, suppliers, and clients outside of their host country. Beyond the firm, expatriation feeds into the competitiveness of cities, acting as a conduit to replenish knowledge, skills, and competences, and has become a significant factor of production for world cities to “win the global war for talent.” In this chapter the author seeks to examine the agency of expatriation as an organizational strategy for the spatial mobility of knowledge and as a global process that enhances the competiveness of world cities. The chapter draws on case studies of expatriation within global accountancy firms and London’s financial district.

Expatriation, and other forms of labor mobility that cross international borders within and between firms is a crucial organizational strategy for the spatial mobility of knowledge in the world economy. At the organizational level, firms deploy their knowledge-rich, managerial, and expert human capital to circulate both tacit and explicit (codified) knowledge between subsidiaries, clients, and suppliers; to develop the organization; and to service existing and new clients outside of the home country. Expatriation is a process that stretches tacit knowledge across time and space (Beaverstock, 2004; Faulconbridge, 2008) because of the importance of “being (there)” (Gertler, 2003) to manage, engage in the production system, and service clients in co-location. Far from being on the wane in these times of advanced information technology and communication, expatriation is a strategic mechanism for a firm to deliver knowledge, skills, expertise, and experience to a particular point in space and time (e.g., an office, subsidiary, or gas extraction field) (Beaverstock, 2004; Edström & Galbraith, 1977; Millar & Salt, 2009; PricewaterhouseCoopers, 2010a; Scullion & Collings, 2006).
Expatriation is a vital global organizational strategy for knowledge-intensive professional services in sectors such as accountancy, consulting, and law in which the delivery of knowledge, tailor-made solutions, and value is embodied in the employee, especially if the reputation and credentials of the firm rests on the success of the professional employee-client relationship (Beaverstock, 2004; Faulconbridge, 2008; Jones, 2008). Beyond the firm, expatriation feeds into the competitiveness of cities and regions acting as a conduit to replenish knowledge, skills, and know-how in local labor markets. Indeed, many world city boosterists and commentators suggest that attracting and retaining global talent is a significant factor of production in the success of a world city in the network society (Beaverstock, 2010; Castells, 1996; Florida, 2002; Wigley, 2008).
The contribution of this chapter is to advance the theoretical and empirical understanding of contemporary forms of expatriation as an organizational strategy for the spatial mobility of knowledge and as a global process that enhances the competiveness of the world city in an age of highly integrated, global information, communication, and telecommunication (ICT) systems. Accordingly, the rest of this chapter is divided into seven parts. Following this introduction, parts two, three, and four focus on explaining the significant concepts that underpin the strategy of expatriation as a physical medium of knowledge creation, transfer, and exchange within organizations and between different spatial contexts. In part two, I examine the structural organization of firms and their mechanisms for creating, sharing, and exchanging knowledge within the multilocation organization, drawing primarily on the work of transnational management theorists, Bartlett and Ghoshal (1998). Part three is a review of human resource perspectives that explain the organizational strategy of expatriation and their role in the firm’s global knowledge management system. I look in part four at the agency of place, the world city, in concentrating and reproducing knowledge management within the network society (Castells, 1996) and enhancing the expatriate’s spatial knowledge networks and career paths (Beaverstock, 2005, 2010). In parts five and six I introduce case studies of expatriation within global accountancy firms and discuss the agency of foreign workers in the competitiveness of London’s financial district (Beaverstock, 2007a, 2010; Beaverstock & Hall, 2012). I conclude in part seven and argue that expatriation will continue to be a significant form of knowledge development, transfer, and exchange within organizations, and an essential driver for spatial economic development and competiveness.
The Firm, International Business Strategy, and Knowledge Management
,…thick web of communication possibilities vertically and horizontally…[where]…[m]anagers’ careers would be varied and involve movement across different subsidiaries as well as into head office. Senior management would reflect a wider group of nationalities and experiences than in the multinational enterprise. Learning would be dispersed, often disorganized but usually multi-directional in terms of its effect. (Morgan, 2001, p. 120)
However, in order to get a more refined and structural explanation of how knowledge is created and shared between a firm’s international subsidiaries, at a conceptual level, one can draw on the writings of two eminent management theorists, Christopher Bartlett and Sumantra Ghoshal, in their widely acclaimed Managing Across Borders: The Transnational Solution (1998). Bartlett and Ghoshal (1998) provide a conceptual model to analyze how corporate knowledge, both tacit and codified, is developed and disseminated within the international multilocational firm which can provide a framework to account for the strategy of firms that engage in global staffing and expatriation.
Organizational characteristics of the transnational firm
Configuration of assets and capabilities
Decentralized and nationally self-sufficient
Centralized and globally scaled
Sources of core competences centralized, others decentralized
Dispersed, interdependent, and specialized
Role of overseas operations
Sensing and exploiting local opportunities and strategies

Differentiated contributions by national units to integrated, worldwide operations
Development and diffusion of knowledge
Knowledge developed and retained within each unit

Knowledge developed at the center and transferred to overseas units
Knowledge developed jointly and shared worldwide
In a similar vein to Bartlett and Ghoshal (1998), Nohria and Ghoshal (1997, p. 4) define the firm as a “differentiated network” reflecting the network structure of the organization made up of a multitude of linkages, chains, and relationships: (a) the local linkages within each national subsidiary; (b) the linkages between headquarters and the subsidiaries; and (c) the linkages between headquarters and the subsidiaries themselves”, with the latter, unlike (b), also including linkages between the subsidiaries.
There is now sufficient evidence to suggest that firms manage their knowledge development and diffusion through complex systems of knowledge management that draw upon a combination of physical and virtual dissemination and exchange, regardless of whether they exhibit Bartlett and Ghoshal’s (1998) international or transnational organizational characteristics (Faulconbridge, 2008; Mellahi, Frynas, & Finlay, 2005). Firms are relational entities with sophisticated knowledge management systems to develop, share, and exchange explicit and codified knowledge through electronic transmission and virtual proximity using efficient and confidential transmission systems and ICT, including videoconferencing software and, latterly, intra-firm social networking systems. But if one considers the development, diffusion, and exchange of tacit knowledge, which is often very sticky and embodied in the experience, competences, expertise, skills, and learning capacities of an individual, the most efficient—and possibly cost-effective—mechanism to transfer those embodied attributes cross-border from subsidiary A to subsidiary B is to move the individual physically through, for example, business travel (Faulconbridge, Beaverstock, Derudder, & Witlox, 2009) or an international assignment (Brewster & Scullion, 1997; Collings, McDonnell, Gunnigle, & Lavelle, 2010; Scullion & Collings, 2006).
Moreover, the advent of the transnational form of the contemporary firm has created the conditions for the development of a globally functioning, international division of highly skilled executive, established professional and managerial, and high-value scientific labor (in fields such as medicine, technology, R&D, and engineering). This global labor market is inherently reproduced through local labor markets, but importantly also through the burgeoning number of international assignments and other types of cross-border hypermobile work (for example, those involved in regular business travel, short-term rotations, and fly-in and fly-out time-specific contract work) present in many industrial sectors of the world economy, such as aerospace and mineral extraction (Millar & Salt, 2009), professional services (Beaverstock, 2004; Faulconbridge, 2008; Jones, 2010), executive education (Hall, 2009), banking and financial services (Beaverstock & Hall, 2012), high technology (Harvey, 2008), and IT and R&D (Mahroum, 2000; Saxenian, 2007). In order to examine further the significance of inter- and intra-firm international assignments as a mechanism for knowledge management and exchange within and between firms, it is important to draw on the International Human Resource Management (IHRM)discipline and to discuss the organizational strategy of expatriation and global staffing systems.
Expatriation, Global Talent, and Knowledge Exchange
Irrespective of significant advancements in global ICT, TNCs use international assignments as a fundamental internationalization strategy to transfer and exchange knowledge, expertise, and learning to and among foreign subsidiaries or other forms of global investment. These international assignments are synonymous with the organizational label expatriation (Brewster, 1991; Tung, 1988). In the discipline of business studies an entirely new branch of management science with the apt name of International Human Resource Management (IHRM) developed in the late 1960s to focus on this segment of a firm’s internal labor market. The crux of this new field is the organizational strategies posited to explain why TNCs use expatriates rather that locally recruited staff in their foreign subsidiaries, whether these are mineral/energy extraction sites in the BRICS (Brazil, Russia, India, China, and South Africa) economies, manufacturing plants in Southeast Asia, or offices in world cities.
as a direct mechanism to fill positions and vacancies in foreign locations facing a lack of locally recruitable, qualified staff
as part of their internal global management development program to enhance the experience, skills, and competences of junior and mid-rank managers and professionals—irrespective of the supply of locally qualified managers in the host location; and
as a way to develop the global organization in regard to corporate strategy, command and control systems, and the sharing of best practice, learning, and knowledge.
Edström and Galbraith’s (1977) study of the rationale for the international transfer of managers within TNCs to fill positions and to develop managers as well as the firm still resonates strongly with contemporary analyses of expatriation (Collings et al., 2010) and, more latterly, scholarship on firms’ global staffing regimes and global talent management (Scullion & Collings, 2006).
In Collings and Scullion’s (2006) review of global staffing and expatriation, they synthesized the findings of other contemporary IHRM scholars in order to interrogate further Edström and Galbraith’s (1977) writings on the foundations of international assignments within TNCs. For example, drawing on Sparrow, Brewster, and Harris’s (2004) research on globalizing human resource management, they note that the TNCs’ organizational strategy for sending staff on an international assignment is sixfold: for career development; to establish an international cadre of managers; to fill local vacancies resulting from a lack of qualified home-country nationals; to transfer expertise; to manage and control foreign assets; and to control global strategy and policy. Furthermore, Collings and Scullion (2006) disaggregate the purpose of expatriation into two conceptual frames (after Evans, Pucik, & Barsoux, 2002). First, they are demand-driven assignments, which resonates with the organizational requirement to fill vacancies, manage new investments, or solve problems in situ because of a dearth of locally qualified home country nationals. Second, they are learning-driven assignments intended to drive individual career development and serve as a mechanism to transfer, share, and exchange knowledge between the expatriate and home country nationals. Most empirical studies of the social characteristics of corporate-transferee expatriates from the United States, Europe, and Japan derived from research by scholars of IHRM indicate these workers are predominately male, with men holding an average of 85 % of such positions across all industrial sectors, as much as 95 % in construction and engineering, and a relatively low 70 % in not-for-profit and charity employment (Shortland, 2009).1
Assignments in the past were typically categorised by organisations as being either short-term or long-term. Today we see many more varied requirements from businesses and assignees and alignment with the organisation’s talent management objectives. Along with short-term and long-term assignments, we have frequent travellers, commuters, intra-regional, and virtual secondments to customers and supplier sites, as well as various assignee and talent types, such as executive, skill set and project-based, developmental, and employee initiated, all creating a need for robust global assignment policy framework. (p. 16)
PricewaterhouseCoopers (2010a, p. 6) predicts that the average number of international assignments worldwide at 900 companies listed in its sample database will have grown 50 % from 2009 levels by 2020 to approximately 400,000. Significantly, PricewaterhouseCoopers suggests that much of this growth in global mobility will be generated by and in the emerging markets, as more skilled employees from these countries enter the global talent pool. Therefore, expatriation as an organizational strategy is an increasingly important facet of the TNC’s portfolio of global talent mobility (Beaverstock, 2010; Faulconbridge et al., 2009; Millar & Salt, 2009). The role of international assignments reflect on the one hand the requirements of the firm to be competitive in a highly globalized world, both in terms of business systems and location, and on the other, the expectations of talent to have high-value-added, mobile careers enhancing promotion prospects, personalremuneration, and a cosmopolitan sense of well-being (Beaverstock, 2011; Beaverstock & Hall, 2012). But it must be acknowledged that more assignees will necessitate “more business travel, more virtual tools, and especially more quick, short-term, and commuter assignments” (PricewaterhouseCoopers, 2010a, p. 4).
World Cities, Expatriation, and the Spatial Mobility of Knowledge
Invariably, in the manufacturing and service sectors of the world economy, the organizational structure and location of the firm provides an overwhelmingly urban working and living experience for the expatriate. Expatriates are city dwellers throughout the globe. But there is a growing body of evidence to suggest their agency, practice, and performativity are crucial processes accounting for the geoeconomic sustainability, competiveness, and relationalities of world cities (Beaverstock, 1994, 2011; Ewers, 2007; Friedmann, 1986; Sassen, 2001a, 2006). Indeed, many commentators have discussed the role of highly skilled international migrants (Beaverstock, 1994, 2005, 2007b), “transnational elites” (Friedmann & Wolff, 1982), the “new international professionals” (Sassen, 2001b), and “dominant managerial elites” (Castells, 1996) in the making of world cities and their complex intercity relations and networks. In many ways, organizational processes of expatriation, talent management, and global staffing are nourishing the knowledge bases of world cities, providing a continuous throughflow of talent into these places that secures them high rankings in the many commercial, highly influential global urban hierarchies, such as Z/Yen’s Global Financial Center Index 11 (2012), Mastercard’s (2008) Worldwide Centers of Commerce Index, or the Mercer Group’s (2011) Quality of Living Worldwide City rankings.
The expatriate, like home country elites, is pulled into world cities and their organizational networks through intra- or inter-company transfers initiated by the firm or potential employer, or through other migratory paths, such as those of free-movers, or European Union (EU) citizens able to migrate at will throughout the EU single market (Favell, 2008). The structural position of world cities in the new international division of labor (Cohen, 1981; Hymer, 1972; Friedmann, 1986) ensures that their spatial economies have unprecedented “global reach” and “command and control” (Sassen, 2001a) derived from high concentrations of corporate headquarters; significant agglomeration economies (clusters) in international finance, professional services, media, and education; health service, medicine, biotechnology, R&D, and creative and cultural industries; cutting-edge information technology and communication; and state-of-the-art infrastructure (Cook, Pandit, Beaverstock, Taylor, & Pain, 2007; Olds, 2007; Sassen, 2006). The firms in these high-value world city economies, whether TNCs or small and medium-sized enterprises in manufacturing or services, create the unprecedented conditions driving demand for highly skilled labor that are articulated in a globally functioning, spatial division of labor (Beaverstock & Boardwell, 2000). Moreover, during the last 40 years or so, the growth of the producer service “complex” in world cities (Sassen, 2006), particularly in those of the Global North—London, New York, Chicago, Boston, Los Angeles, Paris, Frankfurt, Brussels, Madrid, and Amsterdam—have shaped the circumstances for brisk labor market demand in sectors such as advertising, banking, financial services, professional services (accounting, consulting, legal, real estate), and information technology (City of London, 2011). But the growth of the producer complex has not been limited to European and North American cities. For example, in Singapore approximately one million jobs were created in the service sector between 1991 and 2008, of which a third (some 320 thousand) were in financial and professional services, such as accounting, legal, and real estate (Ministry of Manpower, 2009). Similar structural changes are occurring in Moscow (Kolossov, Vendina, & O’Loughlin, 2002), Hong Kong (Meyer, 2000), Shanghai (Lai, 2009), and Mumbai (Patel, 2007).
World city economies are important structural agents in the spatial mobility of knowledge. Their internal structure, global reach, and economic authority, which are manifested in complex intra- and inter-city networks, are perpetuated through the high-value, knowledge-rich labor force attracted to work and live in these places (Beaverstock, 2005). Essentially, world cities are the global melting pots for highly talented workers of all nationalities, both internal and international, who fill vacancies and labor market demand in the high-value-added, knowledge-intensive complexes of the city (whether in finance, professional services, creative industries, the media, or R&D). The bottom line is that expatriation and other forms of mobility such as business travel are key organizational strategies to deliver skills and expertise and to learn at the point of demand, often through the medium of face-to-face interaction. “Face-time” remains a very efficient and valued mechanism to exchange tacit knowledge over time and space, in working environments that depend on direct interaction with clients to ensure quality of service and leadership as well as to deliver tailor-made solutions, problem solving, and complex management systems (Beaverstock, 2007a, 2007b; Faulconbridge, 2008; Jones, 2008).
Finally, it is also important to acknowledge that world cities have significant agency in enhancing an expatriate’s career aspirations, wealth creation, and living experience (Beaverstock, 2005). Spatial career paths facilitate the accumulation and exchange of knowledge and learning within and between different employers and world city postings and living experiences. Expatriate career paths are a conduit in which knowledge is created and consumed in world city networks, particularly in an expatriate’s everyday life experiences and transnational spaces (work, home, social spaces, etc.). The everyday, world-city life-worlds of expatriates supplying knowledge-intensive skills and competencies to the workplace and in “transnational social spaces” (Smith, 1999, p. 120) through “ephemeral networks and practices” (Beaverstock, 2011, p. 711) reproduce specific epistemic communities, whose life courses significantly enhance careers and the accumulation of financial, social, and cultural capital.
Global Staffing and Expatriation in Professional Service Firms
In the international service economy, the World Trade Organization acknowledges that people can deliver services to clients across borders through physical movement. This is an integral part of the General Agreement on Trade in Services (defined as GATS Mode 4) (Organization for Economic Cooperation and Development [OECD], 2003). In professional services, which encompass knowledge-intensive, often tailor-made and highly idiosyncratic services built on reputation and established credentials, the liberalization of trade in “natural persons” (GATS Mode 4) is essential for the firm to circulate knowledge and expertise across borders, embodied in the tacit professionalism and expertise of the archetypal “professions” like architects, accountants, or lawyers (Greenwood & Lachman, 1996; Morris & Empson, 1998; Lowendal, Revang, & Fosstenlokken, 2001). The key asset of a service firm (PSF) is the knowledge capacity of its labor force of both managers and professionals, with capital accumulated, clients courted and serviced, and revenues and profits ultimately accrued through the performance of this workforce and its successful interaction with the client. Morris and Empson (1998) suggest that a PSF is “an organization that trades mainly on the knowledge of its human capital, that is, its employees and the producer-owners, to develop and deliver intangible solutions to client problems” (p. 610). Thus, in PSFs, one of the most efficient mechanisms to deliver knowledge, including the tacit form embodied and stuck to established professionals, is through the physical movement of such professionals from the firm to the client or within the global structure of the firm (Lowendahl, 1997). PSFs supply tailor-made knowledge and expertise to their clients and suppliers and maintain internal organizational control through co-location using personal interaction, expatriation, and hypermobility (Beaverstock, 2007a, 2007b; Faulconbridge, 2008; Faulconbridge, Beaverstock, Taylor, & Nativel, 2011; Jones, 2008; Nachum, 1999).

Global Talent in London’s Financial District
London’s financial district, composed of the City of London and, since the late 1980s, Canary Wharf, has been a magnet for expatriates in banking, finance, and professional services since the end of the twentieth century following the influx of U.S., European, and Japanese banks (Michie, 2000). At the onset of the decade of the 2010s, London is the premier global financial center, ahead of New York, Singapore, and Hong Kong (Z/Yen, 2012). London’s competiveness rests on its ability to attract major U.S., European, and Asian global financial institutions; the quality of its financial environment and regulation; and, importantly, its ability to attract and retain an international, talented labor force in fierce competition with other leading financial centers (Beaverstock, 2010; Cook et al., 2007; Jones, 2010; Z/Yen, 2012). London has a truly deep international talent pool of elite foreign workers of all nationalities from the European Economic Area (EEA) and non-EEA countries (City of London, 2011; Wigley, 2008).
The nature and function of occupations in London’s financial district are very knowledge intensive and essentially cannot be supplanted by information technology or mass recruitment from the local, regional, or national labor market. As research has shown elsewhere (Beaverstock, 1994, 2007b; Jones, 2010; Thrift, 1994), these jobs are highly prized and require a specific set of explicit and tacit knowledge bases, which often require experience working in other financial centers or directly with global clients in secondment arrangements. The cornerstone of these high-value banking and financial services jobs is the ability to work in situ, with a leading process for knowledge exchange and transfer remaining face-to-face contact (Amin & Thrift, 1992; Thrift, 1994). Consequently, a significant driver of the competitiveness and complementariness of London as a global financial center is the continual supply of elite, expatriate labor that comes to work in its burgeoning global banks, financial institutions, and professional services firms. Many of those workers coming into London from outside of the EEA enter as inter-company transfers (ICTs) for specific time periods to fill vacancies, for training, to develop their professional and management skills in formal programs, and to enhance the global culture of the firm (Beaverstock & Hall, 2012).

In this chapter, I have argued that expatriation, also more commonly known as international assignments, remains a key strategy for a firm to transfer and exchange knowledge between subsidiaries and clients alike, irrespective of rapid improvements in ICT and travel. TNCs that engage in international production through foreign direct investment, whether in mineral extraction, manufacturing plant, or office networks, explicitly use expatriation and other modes of corporate mobilities as an organizational strategy to deepen, broaden, and enlarge intrinsic and generic knowledge within the firm. But gone are the days of one way flows of knowledge and people between the headquarters and subservient, knowledge-poor subsidiaries. As Bartlett and Ghoshal (1998) and others (e.g., Morgan, 2001), have quite rightfully acknowledged, contemporary firms are highly transnational in scope, with knowledge being shared among all subsidiaries and people flowing in multiple directions for learning, knowledge transfer and exchange, and the sharing of best practice, whether in management systems or for the rolling out of corporate policy and strategy. In the knowledge-intensive sectors of the economy, which encompass banking, finance, accounting, and legal services, as well as other activities such as advertising, the arts, and even elite sports, expatriation and corporate mobilities are a key modus operandi of the TNC, because idiosyncratic knowledge, skills, expertise, and competences are embodied in the individual worker, a function that can seldom be accomplished by ICT or other forms of technological transmission. As an organizational strategy, expatriation still facilitates the colocation, or immediate proximity of the knowledge-rich employee, of whatever nationality, to the specific client or work colleague to deliver, transfer, or exchange knowledge, which is often in tacit form and sticky. As the study of global accounting firms has shown, international assignments remain a major strategy by which a firm can engage with its clientele and build the knowledge capacity of its worldwide labor force, which is increasingly labeled global talent. Moreover, expatriation and other forms of corporate mobility have become a vital component of firms’ global talent management and global staffing regimes.
Secondly, it is important to acknowledge that world cities are the nodes in society where knowledge is created, co-produced, and circulated within and between firms in similar sectors and agglomeration economies, or clusters. Many leading theorists acknowledge that world cities have economic agency through their command and control functions and global reach (Sassen, 2001b, 2006), with such agency being orchestrated through the strategic operations and everyday decision-making of boardroom executives, fee-earning professionals, and expert scientific labor. Importantly, the composition of this highly skilled labor market is global in scope, composed of both home country nationals and expatriates, who are at the forefront of knowledge production, transfer, and exchange. Indeed, as I have suggested, the world city’s incumbent knowledge economy is continually being nourished by the labor processes of very highly qualified and experienced individuals of all nationalities who bring a degree of depth to the city’s global talent pool. World cities are the places where global talent pools are created, sustained, and, for the very successful cities, such as London, New York, Hong Kong, and Singapore, nurtured and developed. Without such internationally focused and spatialized labor markets being reproduced through expatriation and corporate mobilities, the spatial mobility of both tacit and codified knowledge would circulate very inefficiently between firms and cities, because they are simply just not “being (there)” (Gertler, 2003).
As to the future, the management and capture of global talent is going to be highly competitive for both firms and cities. At the organizational level, corporate mobilities will consist of an array of global talent systems, from expatriation to the hypermobilities of flexipatriation with its business travel and commuting. Firms’ human resource policies will respond more to clients demands for more globally flexible professionals and talented labor to deliver tailor-made solutions and expertise. With respect to world cities, competition to “win the war for talent” (Beaverstock & Hall, 2012) will become rife as cities try to outbid each other with metrics such as high rankings in quality of life indices, remuneration, and sustainability to secure talent to create economic growth and stimulus through highly efficient production and consumption systems.
Research on expatriates in subjects such as their household formation, employment, identity, gender, ethnicity, sexuality, community formation, and mobility also has gathered significant interest across the social sciencesdisciplines, including human geography, sociology, and, of course, migration studies (e.g., Fechter & Walsh, 2012; Smith & Favell, 2006).
