“…In a similar fashion, Aker (2010) analyzes the introduction of cellular phones among grain traders in Niger. She finds that phones allow traders to search for price information over larger areas and sell grains in more markets.…”

The growing use of ICTs around the world, particularly cellular phone technology, provides a significant development opportunity. Under certain situations, ICTs can improve rural households’ agricultural production, farm profitability, job opportunities, adoption of healthier practices, and risk management. All these effects have the potential to increase wellbeing and food security in rural areas of developing countries. Several challenges to effectively scaling up the use of ICTs for development remain, however. Taking advantage of the opportunities provided by ICTs depends on increased connectivity of marginalized population groups, the content and usefulness of the information provided through ICTs, and the capacity of households in rural areas to understand and act on the information that they receive. We need innovative ways to bring together the public and private sectors to ensure that the three Cs (connectivity, content, and capacity) are addressed as a whole.

Access to information and knowledge has always been a challenge for illiterate or low literate learners in developing nations. As a consequence, pedagogical advances, for low literate learners, have lagged behind, as compared to educational strategies for literate or highly literate learners. The technological revolution based on access to Internet and cell-phones has brought new opportunities to one billion low literate learners in the planet. There is evidence that cell-phones are becoming easily available for users in developing nations. "Scientific Animations Without Borders" (SAWBO) creates educational animations that can be watched on cell-phones and other devices and can be transmitted from mobile phone to mobile phone through Bluetooth® technology. In this article we report the results of a short survey conducted by students from Maradi (Niger) with different groups; farmers, teachers in rural areas, informal entrepreneurs and women in which several 3 D animations were showed on mobile phones: cholera prevention, neem seed extract for insects pest control and triple bagging for storage to prevent post harvest looses. The objectives were to find out the perception of usefulness of the content and easiness of the technology used as a mode of transmission of information and knowledge.

“…The empirical approach used for analysis in this paper is most closely related to the work of Jensen (2007), Aker (2008Aker ( , 2010 and to Svensson and Yanagizawa (2009) who all analyze effects of an improved information infrastructure on market efficiency. Utilizing a quasiexperimental setting caused by a gradual roll-out, Jensen (2007) shows that the introduction of mobile phones in the Indian region Kerala increased local fishermen's profits and reduced catchment waste and price dispersion.…”

“…More specifically, we use that warehouses connected to the ECX were gradually implemented across regions in Ethiopia, and analyze differences in difference between regions with and without access to these warehouses. As Aker (2010) and Jensen (2007), we use price spreads between markets as a measure of market efficiency. However, in contrast to Jensen (2007), Aker (2008; and Svensson and Yanigizawa (2009), our focus is not solely on information but rather on the compound effect of warehouses and the presence of a centralized commodity exchange.…”

Terms of use: Documents in 2 AbstractIn this article, we study the impact of an institutional intervention on market efficiency in Ethiopia. More specifically, we study whether regional warehouses that are connected to a national commodity exchange reduce transaction cost and price dispersion between regions. In order to identify the causal effect we take advantage of the fact that the warehouses that are connected to the Ethiopian Commodity Exchange were sequentially rolled out. Using retail price data and information about warehouse operation from 2007-2012, we find that the average price spread between market pairs is reduced by 0.86-1.775 ETB when both markets have an operating warehouse. This is a substantial reduction considering that the average price spread over the full period is 3.33 ETB.
