Drivers of Knowledge Contribution in Open Fora: Findings from Wikipedians

Abstract: Today’s social computing platforms include many open content fora where users voluntarily create and edit content online. This has opened up a new mechanism for knowledge acquisition raising related research questions, including identification of the reasons why people contribute to open fora. While altruism is mentioned most frequently, it has been suggested that there may be additional drivers in play. To explore this possibility, we examine contribution behavior in the Wikipedia context using qualitative data from two focus groups of Wikipedians. Content analysis of the data reveals a number of different drivers of contributor behavior which we then map into the Motivation-Ability-Opportunity (MAO) theoretical framework developed in the organizational behavior literature on work performance. The mapping can provide a theoretical basis for quantitative examination of contributor behavior and lead to more effective methods of managing collective knowledge in other open forum settings, such as corporate wikis.

SEZs as Growth Engines - India vs China

Abstract: Foreign direct investment (FDI) as tool to boost growth of economy has been recognized by several developing countries like Brazil, China, India, Taiwan etc. According to IMF, FDI is an international investment to obtain a lasting interest by a resident entity in one economy in an enterprise resident in another economy. It results in a long-term relationship between the direct investor and the enterprise and a significant degree of influence by the investor in the management of the enterprise including management control. FDI is usually preferred over FII as FIIs are assumed to be attracted by short term gains and tend to leave during times of trouble. In contrast to it, FDI investor cannot be pull out quickly, due to lasting interest in the investment made and hence, more stable. Developing countries though are trying to attract FDI but bulk of the FDI is still absorbed by the developed countries ($1.5 trillion in US in 2004). China and India are two Asian giants which have lately been on the forefront of FDI investments and both countries have evolved policies and implemented reforms to attract investments. This is mainly achieved through the establishment of Special Economic Zones in both the countries. This Paper is aimed at identifying the efficacy of the SEZs and their contribution towards achieving the double digit growth in both the countries.

Impact of information arrival on volatility of intraday stock returns

Abstract: In this empirical study we have considered the impact of information flow on the volatility of a particular stock using high frequency return and news data on the Eu- rostoxx 50 market. In addition to using volume as a proxy for information flow, we have included company specific announcements, to the conditional variance of the Gen- eralized Autoregressive Conditional Heteroscedastic model (GARCH). For this purpose we have constructed five measures of the impact of public information flow in the mar- ket transforming commonly available news scores through dierent techniques such as linear and exponential decreasing weight, impact function etc. We have analyzed the behaviour of volatility, estimated by squared returns for the next 4 hours after arrival of a non overlapping news, having a significant impact on the firm's stock return. A signif- icant impact of the information flow accessed by the news score coecient is observed for majority of in our analysis. Furthermore, the inclusion of the news scores variable improves the overall model in the sense that it increases the likelihood value of the model. However we do not observe any significant change in the volatility persistence due to inclusion of our news variable.
