Leveraging micro‐ and macro‐structures of embeddedness in alliance networks for exploratory innovation in biotechnology

Researchers agree that alliance networks can be an important instrument in a firm's innovation process, but there is limited empirical evidence on actually how they facilitate the creation of new knowledge for exploratory innovation. The research question is what alliance network configuration is optimal for exploratory innovation. The present study investigated the interaction between a firm's alliance portfolio structure (the micro‐level) and the industry alliance network structure (the macro‐level), and it empirically tested how their interaction may be affecting the exploratory innovation outcome of network participating firms in the biotechnology industry. The paper uses data from exploratory patents filed by 455 dedicated biotechnology firms in 1986–1999 and an overall network comprising 2,933 technological alliances over the same period. The results indicate that, in the case of biotechnology, firms with high exploratory innovation output have short path indirect access to many other firms (micro‐level), and operate in dense industry alliance networks centralized around a few key firms (macro‐level), and that these effects are curvilinear.     

Episodic Nonlinearity in Leading Global Currencies

We perform non-linearity tests using daily data for leading currencies that include the Australian dollar, British pound, Brazilian real, Canadian dollar, euro, Japanese yen, Mexican peso, and the Swiss franc to resolve the issue of whether these currencies are driven by fundamentals or exogenous shocks to the global economy. In particular, we use a new method of testing for linear and nonlinear lead/lag relationships between time series, introduced by Brooks and Hinich (J Empir Finance 20:385–404, 1999), based on the concepts of cross-correlation and cross-bicorrelation. Our evidence points to a relatively rare episodic nonlinearity within and across foreign exchange rates. We also test the validity of specifying ARCH-type error structures for foreign exchange rates. In doing so, we estimate Bollerslev’s (J Econom 31:307–327, 1986) generalized ARCH (GARCH) model and Nelson’s (1988) exponential GARCH (EGARCH) model, using a variety of error densities [including the normal, the Student-t distribution, and the Generalized Error Distribution (GED)] and a comprehensive set of diagnostic checks. We apply the Brooks and Hinich (1999) nonlinearity test to the standardized residuals of the optimal GARCH/EGARCH model for each exchange rate series and show that the nonlinearity in the exchange rates is not due to ARCH-type effects. This result has important implications for the interpretation of the recent voluminous literature which attempts to model financial asset returns using this family of models.     

Too scared to go sick? The management and the manifestations of workplace attendance in the food retail sector

This article is a response to Taylor et al’s (2010) call for further research regarding workplace attendance. It examines the new politics of absence management in the UK and Cyprus in food retail sector, identifying a dual approach in managing attendance across the two countries. The first approach suggested the penalization of absence, whilst the second focused on the prevention of absence through accommodation. The article argues that ‘coercion’ is not the sole vehicle to tackle high absence in food retailing rather it suggests the development of other practices to enhance cooperation to regular attendance. The research identifies significant differences regarding the formality of these processes between the two countries, and suggests the generation of a particular attendance culture within the organisations, one that is not merely a culture of fear, as Taylor et al (2010) suggest, but rather a culture that includes accommodation and cooperation.     

New entry,strategic diversity and efficiency in soccer betting markets: the creation and suppression of arbitrage opportunities

ABSTRACT

We find that prices offered by competing bookmakers within the same quote-driven soccer (football) betting market provide arbitrage opportunities. However, the management practices of bookmakers prevent informed bettors exploiting these in practice. We identify two groups of bookmakers, ‘position-takers’ and ‘book-balancers’. Position-takers alter their odds infrequently, while actively restricting informed traders. Book-balancers actively manage inventory by adjusting odds, and place few restrictions on their customers. We identify 545 arbitrage portfolios, and find that around 50% would require a bet on the favourite at the position-taking bookmaker. The management practices of position-takers generally prevent these opportunities being exploited in practice.     

The spatial impact of EU Pan-European transport axes: City clusters formation in the Balkan area and developmental perspectives

This article explores the spatial and development implications of the Pan-European Transport Axes in the Balkans. For that purpose, the potential Development Poles and Axes are determined, on the basis of size, the location of cities, their interconnection and their role as hubs of the Pan-European axes. This is achieved by means of the formation and implementation of a methodology based on the use of special statistical applications. According to data analysis, three geographical units arise: Central Core, Peripheral Zone, Perimetric Zones. In the analysis that follows, Advantages, Weaknesses, Opportunities and Threats are examined in each case and suggestions are made as regards the policies required.     

Human resource involvement,job-related factors,and their relation with firm performance: experiences from Greece

A great deal of debate exists regarding the relationship between human resource (HR) practices and firm performance. The purpose of this paper is to examine the relationship between HR involvement in firm's strategic planning, job-related constructs (job characteristics, workplace characteristics, and satisfaction), and their impact on firm performance. A new research model is proposed exploring the above-mentioned relationships. The validity of this model is tested using data from 106 chief executive officers (CEOs), top managers, and managing directors of Greek small medium enterprises (SMEs)), using the structural equation modeling approach. The results indicate that job characteristics and workplace characteristics directly affect satisfaction and firm performance, while HR involvement has a direct impact on job characteristics and workplace characteristics and an indirect effect on satisfaction and firm performance. It is suggested that managers should emphasize on the HR involvement in the process of strategic planning which actually affects the job-related constructs, in order to improve employees' satisfaction and achieve higher firm performance levels.     

A multi-criteria game theory and real-options model for irreversible ICT investment decisions

The information and communication technology (ICT) industry is one of the most capital intensive among the high-technology industries. ICT business analysis, especially after the industry deregulation, has become a difficult task. Traditional quantitative cost–benefit analysis concerning investment decisions is by no means sufficient for capturing the complexity of the problem in its entirety. This work combines quantitative and qualitative analyses for modeling competitive interactions between players in the ICT business field. The proposed decision analysis model combines real options, game theory, and analytic hierarchy process for analyzing ICT business alternatives under the threat of competition. The proposed model is applied to a real broadband technology business case, showing how it can be formulated and solved.     

Equilibrium conditions in corporate tax competition and Foreign Direct Investment flows

We consider a collection of countries which attempt to maximize their corporate tax revenue, the latter being viewed as a function of Foreign Direct Investment (FDI) inflow and the Effective Average Tax Rate (EATR) which each country sets for itself. Under a model that assumes a direct influence of tax differentials on the flow of FDI, each country's decisions are naturally ‘coupled’ to those of others, leading to a non-cooperative game in which countries–players compete for FDI inflows by sequentially altering their tax rates. Their decisions are made via a differential equation-based model used to predict the effect of tax rate changes on a player's share of FDI inflows. Our model, calibrated using empirical data from 12 OECD countries for the period 1982–2005, combines FDI inflow and tax-rate differentials to arrive at a “steady-state” FDI inflow share for each player, given its competitors' corporate tax rates. We explore the game's equilibrium, including the question of whether equilibrium necessarily implies a ‘race to bottom’, with low corporate tax rates for all players.     

Economic Crisis and its Impact on Promotion and Media in Cyprus

ABSTRACT

The economic crisis has redounded sharply upon marketing communications and media vehicles in Cyprus. In recession periods, communication and marketing budgets can contract while companies seek to obtain the best communication outcomes with more limited resources, both the size and the distribution of the communication mix can alter rapidly. This qualitative paper reveals that Cypriot advertising agencies now place greater emphasis upon marketing public relations (MPR) as it is perceived to be cost effective and efficient in achieving campaign objectives. The empirical data also indicates a shift towards the use of internet marketing and social media as more and more businesses are realizing the importance of consumer generated marketing and word-of-mouth/mouse marketing (WOMm).     

Asset Prices and the Financial Crisis of 2007–09: An Overview of Theories and Policies

The financial crisis of 2007–09 has led to a rethinking of the role of monetary and financial regulatory policy. It has also called into question the benefits of financial innovation and monetary policy that focuses solely on inflation and the output gap. This paper discusses financial instabilities in general, the recent financial crisis as well as the appropriate role of monetary and financial regulatory policy in dealing with asset bubbles. The paper concludes by evaluating appropriate policies to reduce the economic impact of future financial crises.
