The determinants of firm diversification in UK quoted companies

This paper examines the role of resource-based and governance factors in determining the boundaries of UK quoted companies, measured by both the probability and intensity of market diversification. Using a panel of over 2000 firms for the period 1988 to 2001 it is found that firm-level heterogeneity and industry characteristics account for the variability in diversification behaviour and that resource-based and governance factors interact in a complex manner not necessarily fully explained by the theoretical literature. The results also indicate that the degree of data aggregation has significant implications for the empirical modelling of market diversification.     

Postmodernity,globalisation and nationalist conflict in the former Yugoslavia

During the 1990s, several of the conflicts that have demanded most media attention have been associated with the disintegration of the Yugoslav Federation. A number of attempts have been made to outline the main causes of these, but these causal factors remain difficult to describe definitively, largely owing to the complexity of the post‐Yugoslav political landscape. This paper studies the validity of employing a postmodern paradigm for investigating the conflicts in former Yugoslavia, as well as other current conflicts, arguing that the present cultural and philosophical context has to be addressed. After an outline of some of the key aspects of postmodernity, the focus centres on the importance of the media and the postmodern perspective on the issue of the nation state. Key theories related to postmodern conflict, with relation to economic and cultural factors, are outlined. These are evaluated as regards their applicability to the Yugoslav conflicts and ‐ by extension ‐ to all future wars in the postmodern era.     

Habit persistence in assets demand

Habit persistence is examined for six asset demand categories using U.S. data and a dynamic forward-looking model. We find habit persistence is greater for more liquid assets compared to riskier assets and may in part explain low holdings of riskier assets. Cash assets are found to be substitutes with other liquid assets under habit formation. Consistent with portfolio analysis, the riskier asset categories of money market mutual funds and bonds are found to be complements in use. The three more risky asset categories have budget elasticities greater than unity indicating that in the long run consumers are more likely to turn to these assets as their wealth increases.     

Econometric Methods for Modelling Systems With a Mixture of i(1) and i(0) Variables

This paper considers structural models with both I(1) and I(0) variables. The structural shocks associated with either set of variables could be permanent or transitory. We classify the shocks as (P1,P0) and (T1,T0), where P/T distinguishes permanent/transitory, while 1/0 means they are attached to structural equations with either I(1) or I(0) variables as their ‘dependent’ variable. We show that P0 shocks can affect cointegration analysis and provide a formula to compute the permanent component if they are present. Finally, we reformulate a well‐known empirical structural vector autoregression showing the impact of P0 shocks when there are just long‐run parametric and sign restrictions.

Discretionary technology bootlegging tensions in institutional healthcare work

We explore individuals who take some of their technology use ‘underground’, described as ‘bootlegging’, to enhance healthcare work. We find that healthcare professionals’ informal use of mobile applications in healthcare work sometimes ‘sticks out’ and this produces professional identity tensions: (1) conflict with perceptions of professional behaviour, and (2) defilement of expert judgment. Our analysis, moreover, reveals that identity work (i.e. ‘accepting’ and ‘sensemaking’) provides a coping mechanism to deal with these unresolved professional identity tensions. This paper contributes to a better understanding of the constitutive entanglements and two‐way interactions of discretionary technology bootlegging, professional identity and autonomy in institutional healthcare work.     

Online customer experience in e-retailing: implications for web entrepreneurship

Providing consumers with unique experiences and immersing them in original contexts are the goals of web entrepreneurs. Researchers and web entrepreneurs have expressed a particular interest in the online customer experience, agreeing on its importance in creating satisfaction, revisiting intention, e-trust and e-loyalty. This paper explores customer experience in the online retail context. The online customer experience is central in forming customers’ perceptions of expectations of online retailers because this experience is highly personal. However, empirical research on the online customer experience remains scarce. The objectives of this unique study are twofold. The first is to compare the effect of online customer experience on the responses of Romanian and Tunisian customers. The comparative analysis is based on two dimensions of the online customer experience assessment tool. These dimensions are cognitive experiential state (flow) and affective experiential state. The second objective is to examine the contribution of each of these two dimensions in explaining overall perceived value, e-satisfaction, e-trust and repurchase intention in the online context, as well as their effects on web entrepreneurial initiatives. The findings reveal the impact of cultural influences on the constructs embedded in the research framework. The implications for practice relate to the increasing importance of online customer experience in tailoring online marketing campaigns. The implications for web entrepreneurship are clearly emphasised by the pathways from online customer experience to entrepreneurial initiatives. These pathways capture the value of customer-generated content in designing innovative business models.

     

Tourism,changing architectural styles,and the production of place in Itacaré, Bahia,Brazil

This article examines changing architecture in Itacaré, Brazil, as it transitions from a fishing village to an international tourist destination. Tourism, as an assemblage of practices and perspectives, recreates places in specific ways that structure social and environmental relationships. Through an examination of historical architectural styles, tourist architecture, and popular architecture in Itacaré, this article analyses the ways a tourist economy has physically and socially rebuilt the city. Socially, the changing architecture marks and creates differences between class, racial, and regional identities while also providing an idiom through which public conversations about these changing economic systems and demographics are articulated. At the same time, the expansion of the city has led to racial-, regional-, and class-based segregation. Environmentally, tourist architecture creates new relationships to nature through re-imagining Itacaré’s position in relation to other rural and urban places and a new emphasis on the aesthetic value of nature.     

Cambium non est mutuum: exchange and interest rates in medieval Europe

A major gap in our understanding of the medieval economy concerns interest rates, especially relating to commercial credit. Although direct evidence about interest rates is scattered and anecdotal, there is much more surviving information about exchange rates. Since both contemporaries and historians have suggested that exchange and rechange transactions could be used to disguise the charging of interest in order to circumvent the usury prohibition, it should be possible to back out implied interest rates from exchange rates. The analysis presented in this article is based on a new dataset of medieval exchange rates collected from commercial correspondence in the archive of Francesco di Marco Datini of Prato, c. 1383–1411. It demonstrates that the time value of money was consistently incorporated into market exchange rates. Moreover, these implicit interest rates are broadly comparable to those received from other types of commercial loan and investment. Although on average profitable, the return on any individual exchange and rechange transaction did involve a degree of uncertainty that may have justified their non‐usurious nature. However, there were also practical reasons why medieval merchants may have used foreign exchange transactions as a means of extending credit.
