Foreign Direct Investment Liberalization Between Canada and the USA: A CGE Investigation

In this paper, we develop a computable general equilibrium (CGE) model to shed quantitative light on the implications of a scenario of deeper economic integration between Canada and the United States, where the barriers for foreign direct investment are preferentially eliminated. Our model distinguishes between the activities of domestic and foreign-owned firms at the microeconomic level, both in terms of demand and production characteristics. Overall our findings suggest that further investment liberalization between the two countries will accelerate the shaping of Canada’s industrial structure, as manifested by recent trends.

University–firm competition in basic research: Simultaneous versus sequential moves

This paper studies the endogenous timing of moves in a game with competition in basic research between a university and a commercial firm. It examines the conditions under which the two entities end up investing in innovation at equilibrium, both under simultaneous and sequential moves. It argues that when the innovation process is not too costly, under any timing, the firm conducts research despite the opportunities for complete free-riding. The two sequential move games with either player as leader emerge as equilibrium endogenous timings, with both entities realizing higher profits in either outcome than in a simultaneous move game. Each entity also profits more by following than by leading. Finally, as a proxy for a welfare analysis, we compare the propensities for innovation across the three scenarios and find that university leadership yields a superior performance. This may be used as a selection criterion to choose the latter scenario as the unique outcome of endogenous timing.     

Assessing output and productivity growth in the banking industry

This paper assesses the evolution of output and productivity in the Greek banking industry for the period 1990–2006. Three main categories of bank output were estimated based on modern theoretical approaches, while for the estimation of output and productivity (partial and total factor) we relied on the index number method (Tornqvist index). We also considered the effect of labor quality on banks’ productivity and the contribution of total factor productivity to bank output growth. Bank output and labor productivity outpaced considerably the respective GDP growth and labor productivity of the Greek economy during the period under examination. Capital and total factor productivity have also improved remarkably mainly since 1999, due to the structural changes that took place within the industry, capital (mainly IT) investments and improvement in the quality of human capital.     

Other voices,other rooms: differentiating social identity development in organisational and Pro‐Am virtual teams

This paper advocates a social identity approach as a way to overcome the normative limitations of existing virtual team identity research. We also explore how social identity understandings of virtual team identity could benefit from incorporating comparisons between organisational and professional amateur virtual teams; and a focus on technologically mediated dialogues.     

On the Use of the Moving Average Trading Rule to Test for Weak Form Efficiency in Capital Markets

The examination for the possible existence of predictive power in the moving average trading rule has been used extensively to test the hypothesis of weak form market efficiency in capital markets. This work focuses mainly on the study of the variation of the moving average (MA) trading rule performance as a function of the length of the longer MA. Empirical analysis of daily data from NYSE and the Athens Stock Exchange reveal high variability of the performance of the MA trading rule as a function of the MA length and on some occasions the series of successive trading rule total returns is non‐stationary. These findings have direct implications in weak form market efficiency testing. Indeed, given this high variability of the performance of the MA trading rule, by just finding out that trading rules with some specific combinations of MA lengths can or cannot beat the market, as is the case in most of the published work thus far, is not enough evidence for or against the existence of weak form market efficiency. Results also show that on average in about three out of four cases trading rule signals are false, a fact that leaves a lot of space for improved trading rule performance if trading rule signals are combined with other information (e.g. filters, or volume of trade). Finally, some evidence of enhanced trading rule performance for the shorter MA lengths was found. This enhanced performance is partly attributed to the higher probability that a trading rule signal is not a whipsaw, as well as to the larger number of days out‐of‐the‐market which are associated with shorter MA lengths.     

Emotions and the spatialisation of social relations in text‐based computer‐mediated communication

This paper advances our knowledge of emotions in virtual teams using text‐based computer‐mediated communication. The literature's preoccupation with the absence of physical cues of emotion has meant we lack both an understanding of how emotions are co‐constructed through interaction and an explanation of their role in the social relations of virtual teams. Adopting a communicative view of emotion, we present the findings of a longitudinal study of a virtual team within a transnational collaborative project. We present three aspects of interaction that demonstrate how team members' experience and understanding of the emotions expressed through, and suppressed from, text‐based messages are influenced by the styles and patterns of interaction enabled by technology. Where our three aspects tend towards stasis, we argue that emotion provides a temporal dimension to a process of ‘spatialising’ social relations by connoting what should change, or what should endure, between people.     

Macroeconomic outcomes,collective bargaining and intersectoral productivity differentials: a panel approach

Using a sample of 19 advanced countries from 1990 to 2014 and an Arellano–Bover/Blundell–Bond linear dynamic GMM estimator along with a bootstrap-based bias correction fixed effects estimator for dynamic panels, the paper examines the macroeconomic impact of collective bargaining structures in a context of varying intersectoral heterogeneity in productivity growth among the exposed and sheltered sectors of the economy. Results show a dampening impact of pattern and centralized bargaining structures on unemployment. However, strong domestic demand is a key precondition for such a favourable effect to materialize. Uncoordinated and centralized bargaining structures are the most efficient in terms of labour cost restraint while industry bargaining moderates labour cost growth as intersectoral productivity differentials widen.     

Economic aspects and the Summer Olympics: a review of related research

As the Summer Olympics are growing with larger media coverage and sponsorship, host cities have started to attach great importance to the tourism and other likely economic effects that occur by staging such a special event. As a result, a number of studies have been conducted to consider the various economic implications on the hosts. This paper examines and evaluates methods and assumptions used by the economic studies. It also compares ex‐ante models and forecasts with the ex‐post approach. The aim is to improve the information available to policy makers and potential future hosts of Summer Olympics and other mega‐events. Copyright © 2003 John Wiley & Sons, Ltd.
