In this paper we examine the effect of technology on economic growth in Zimbabwe over the period 1975–2014 whilst accounting for structural breaks. We use the extended Cobb–Douglas type Solow (Q J Econ 70(1):65–94, 1956) framework and the ARDL bounds procedure to examine cointegration and short run and long run effects. Using unit root tests, we note that structural changes in Zimbabwe are generally marked by the period 1982 onwards. We find that mobile technology has a positive short-run (0.09 %) and long-run (0.08 %) impact on the output per capita. The structural changes post-1982 periods show positive impact in the short-run (0.06) and the long-run (0.09), whereas the coefficient of trend in the short-run (−0.03) and the long-run (−0.04) is negative. The Granger non-causality test shows a unidirectional causality from capital stock (investment) per capita to output per capita and a bi-directional causality between mobile cellular technology and output per capita. The plausible reasons for estimated magnitude effects and the direction of causality are explained for policy deliberation.

The use of social media has spread into many different areas including marketing, customer service, and corporate disclosure. However, our understanding of the timely effect of financial reporting information on Twitter is still limited. In this paper, we propose to examine the timely effect of financial reporting information on Twitter in Australian context, as reflect in the stock market trading. We aim to find out whether the level of information asymmetry within the stock market will be reduced, after the introduction of Twitter and the use of Twitter for financial reporting purpose

The use of social media has spread into many different areas including marketing, customer service, and corporate disclosure. However, our understanding of the timely effect of financial reporting information on Twitter is still limited. In this paper, we examine the timely effect of financial reporting information on Twitter in the Australian context, as reflected in the follow-up stock market reaction. With the use of event methodology and comparative setting, we find that financial reporting disclosure on Twitter reduces the information asymmetry level. This is evidenced by reduction of bid-ask spread and increase of share trading volume. The results of this study imply that financial reporting disclosure on social media assists the dissemination of information and the stock market response to this information

In this paper I examine how one political actor–former Prime Minister Kevin Rudd–proposes to use education for the purpose of securing national productivity and foreign policy. I work with Foucault’s suggestion that the apparatus of security is the essential technical instrument of governmentality and that the production of milieu, made up of human, spatial, temporal and cultural objects, and the government of risk are key strategies in the bio-politicisation of security. The discourse analysis also draws on Bacchi to problematise statements that (a) represent both the nation and regional neighbours as governable milieu within the ambit of a whole of government approach, and (b) locate literacy and education as both risk and solution in a security apparatus. My examination of the emergence of literacy and education as security technologies, takes account of the discursive effects of Rudd’s representation of the spaces and scale of national, geopolitical and global policy problems. I argue that in these examples of policy texts, education is used as a discursive tool to secure education workers and youth as subjects of economic interest and sovereign rule.
