Social Media in Organizations: Leveraging Personal and Collective Knowledge Processes

By using social media, many companies try to exploit new forms of interaction, collaboration, and knowledge sharing through leveraging the social, collaborative dimension of social software. The traditional collective knowledge management model based on a top-down approach is now opening up new avenues for a bottom-up approach incorporating a more personal knowledge management dimension, which could be synergized into collective knowledge using the social-collaborative dimension of social media. This article addresses the following questions: (1) How can social media support the management of personal and collective knowledge using a synergetic approach? (2) Do the personal and collective dimensions compete with each other, or can they reinforce each other in a more effective manner using social media?

Our findings indicate that social media supports both the personal and collective dimensions of knowledge, while integrating a social collaborative dimension. The article introduces a framework that classifies social software into four categories according to the level of interaction and control. With certain tools, individuals are more in control. With other tools, the group is in control, resulting in a higher level of interaction and a diversity of knowledge and mindsets brought together. However, deploying and adopting these new tools in an organizational context is still a challenging task for management, owing to both organizational and individual factors.     

Competition and ownership structure: Substitutes or complements? Evidence from the Warsaw Stock Exchange

In this paper we analyse the impact of product market competition and ownership structure on firm performance. Our results show that product market competition has a positive and significant impact on performance. Concerning the effect of ownership concentration, we find a U–shaped relationship with performance. Firms with relatively dispersed and relatively concentrated ownership have higher productivity growth than firms with an intermediate level of ownership concentration. This correlation between concentration of ownership and productivity growth is not explained by the type of the controlling shareholder. Finally, product market competition and good governance tend to reinforce each other rather than to be substitutes. Competition has no significant effect on performance for the firms with ‘poor’ governance; on the contrary, it has a significant positive effect in the case of firms with ‘good’ corporate governance.

Aid and trade

This paper surveys the recent theoretical and empirical literaturethat explores the relations between aid and trade and asks aboutthe complementarity or substitution effects at work. We distinguishbetween the effects of aid on trade flows and on trade policies,of the donor as well as the recipient countries. Special focusis given on trade facilitation, or ‘aid for trade’.     

Trade in the Triad: how easy is the access to large markets?

Abstract. In this paper, we measure market access between the United States, the EU, and Japan (the Triad), using the effect of national borders on trade patterns. We investigate overall and industry‐level trends of bilateral trade openness and provide explanations for those using proxies for bilateral observed protection (tariffs and NTBs), home bias of consumers, product differentiation, and levels of FDI. The explanations related to actual protection, home bias and substitutability of goods put together explain a large part of the border effect between blocs of the Triad, although they do not explain the whole of the border effect puzzle.

Amazon's evolving ecosystem: A cyber-bookstore and Application Service Provider

Amazon.com has been through several stages of development: first as a cyber-bookstore, then a cyber-market, and now an Application Service Provider (ASP). I apply the concept of “business ecosystem” to describe the evolution of Amazon.com, and highlight the role of web services in the shaping of its ecosystem. The company plays a central role in the ecosystem, working with a network of partners to bring products and services to customers. By continually trying to improve the health of its ecosystem, Amazon ensures its own survival and prosperity. The mechanisms through which Amazon has created its ecosystem are discussed and ideas for firms looking to create analogous business communities are advanced. Copyright © 2009 ASAC.

Testing Mundell's Intuition of Endogenous OCA Theory*

This paper presents an empirical assessment of the endogenous optimum currency area theory. Frankel and Rose (1998 ) study the endogeneity of a currency union through the lens of international trade flows. Our study extends Frankel and Rose's model by using FDI flows to test the original theory developed by Mundell in 1973. A gravity model is used to empirically assess the effectiveness of the convergence criteria by examining location‐specific advantages that guide multinational investment within the European Union. A fixed effects model based on a panel data of foreign direct investment (FDI) flows within the EU‐15 shows that horizontal investment promotes the diffusion of the production process across the national border. Specifically, our results suggest that economic convergence ensured by belonging to the common currency area helps double FDI flows.     

EMU: Optimal Fiscal Strategy and the Punishment Effectiveness

This paper investigates the ability of the Stability and Growth Pact to prevent governments in the "euro zone" from running excessive budget deficits. It is shown that in a static two-country game, the Pareto-optimal strategy of no excess deficits cannot be systematically enforced, whatever the toughness of the sanction under the Pact. However, in a multiperiod setting, the Pareto-optimal configuration of no excess deficits would prevail even if no sanctions were applied to deviant governments. In this case, neither a heavily punitive SGP, nor a centralized budget appears to be helpful in the EMU context.     

Are Older Workers Harmful for Firm Productivity?

This paper investigates the effects of the workforce age structure on the productivity of large Belgian firms. More precisely, it examines different scenarios of changes in the proportion of young (16–29 years), middle-aged (30–49 years) and older (more than 49 years) workers and their expected effects on firm productivity. Using detailed matched employer–employee data, we find that young workers are significantly more productive than older workers. Yet, results also show that age structure effects on productivity: (i) have substantially decreased over time and (ii) are much stronger in ICT than in non-ICT firms.     

When NGOs go global: Competition on international markets for development donations

Why are many large non-governmental organizations (NGOs) becoming multinational entities? What are the welfare implications of this integration of markets for development donations? To answer these questions, we build a simple two-country model with horizontally differentiated NGOs competing in fundraising. We find that NGOs become multinational if the economies of scale in fundraising are sufficiently large. In that case, national NGOs in the smaller country disappear, while some national NGOs remain in the larger country only if country sizes are sufficiently different. Social welfare is higher in the regime with multinationals than under autarky.
