India is predominantly an agricultural country and its 65% of the population resides in villages. Spread of technology in those areas has been a difficult task because the tools for spread of technology in those areas are lacking. However the announcement of Reserve Bank of India on 12.06.2008 permitting banks to use latest technology like v-Set etc. and formulating long term planning for the same is a welcome step. Internet banking is becoming one of the most convenient ways of delivering financial services in the future. The information technology is becoming an important factor in the future development of financial services industry and specially banking industry in India and may become a convenient tool to attain financial inclusion. Banks are faced with a number of important questions, for example, how to take full advantage of new technology opportunities, how e-developments change the ways customers interact with the financial services provider etc. If we go through the data, we will find that India has a internet penetration of over 3.7% only which requires attention. We have some of our limitations which need to be reviewed and necessary strategy is to be sorted out to make the facility more popular and more reachable among the general masses. Some of limitations are given below. Higher rural population. Late adoption of technology by India. Lack of long term planning by Banks. Lack of awareness among potential users. Optimum utilization of technology in hand. On the other hand, there are some drivers of change like cost effectiveness, competition etc. Latest econometric survey of Dec. 2007 indicates to contradict the hypothesis that public sector banks in India per se are inefficient. Increasing proliferation of mobile services and ATMs in rural areas of India has created a new opportunity to attain financial inclusion. A very high percentage in rural areas is capable to handle new technology if presented to them in their mother tongue. We cannot ignore the fact that the one way of implementation also goes through rural India and the public sector banks already having deep penetration in rural areas have that capability and potential to accomplish this project.

The airline industry is currently undergoing radical changes in how it operates. Nowhere is this shake-up more apparent than with Delta Air Lines and its competitors.Company History and Background The longest-running airline carrier, Delta Air Lines began in 1924 as a crop-dusting company called Huff Daland Dusters. Delta has since become a world leader in providing efficient, on-time air travel. Since 1941, the company has been based in Atlanta, where Hartsfield-Jackson International Airport serves as its largest domestic hub and primary base for flights to over 57 countries. The airline also operates four other hubs in major U.S. cities, notably Los Angeles which it has recently reestablished. Depending on which measure is used, Delta is either the second or third largest airline in the world. Due to competition from low-cost airlines, the negative effects of 9/11 on travel and skyrocketing fuel prices, the company held over $20 billion in debt as of Sept. 2005 and declared bankruptcy. Delta was able to emerge from bankruptcy in 2007, achieving profitability that same year. In April 2008, Delta announced its intention to purchase Northwest Airlines; the two companies combined would create the world's largest airline.

The Internet interface poses a difficulty for buyers in evaluating products online, particularly physical experience and durable goods, such as used cars. This increases buyers' product uncertainty, defined as the buyer's perceived estimate of the variance in product quality based on subjective probabilities about the product's characteristics and whether the product will perform as expected. However, the literature has largely ignored product uncertainty and mostly focused on mitigating buyer's seller uncertainty. To address this void, this study aims to conceptualize the construct of product uncertainty and propose its antecedents and consequences in online auction marketplaces. First, drawing upon the theory of markets with asymmetric information, we propose product uncertainty to be distinct from, yet affected by, seller uncertainty. Second, based on auction pricing theory, we propose that product uncertainty and seller uncertainty negatively affect two key success outcomes of online marketplaces: price premium and transaction activity. Third, following information signaling theory, we propose a set of product information signals to mitigate product uncertainty: (1) online product descriptions (textual, visual, multimedia); (2) third-party product certifications (inspection, history report, warranty); (3) auction posted prices (reserve, starting, buy-it-now); and (4) intrinsic product characteristics (book value and usage). Finally, we propose that the effect of online product descriptions and intrinsic product characteristics on product uncertainty is moderated by seller uncertainty. The proposed model is supported by a unique dataset comprised of a combination of primary (survey) data drawn from 331 buyers who bid upon a used car on eBay Motors, matched with secondary transaction data from the corresponding online auctions. The results distinguish between product and seller uncertainty, show the stronger role of product uncertainty on price premiums and transaction activity compared to seller uncertainty, empirically identify the most influential product information signals, and support the mediating role of product uncertainty. This paper contributes to and has implications for better understanding the nature and role of product uncertainty, identifying mechanisms for mitigating product uncertainty, and demonstrating complementarities between product and seller information signals. The model's generalizability and implications are discussed.

We present the application of network theory to the Dutch payment system with specific attention to systemic stability. The network nodes comprise of domestic banks, large international banks and TARGET countries, the links are established by payments between the nodes. Traditional measures (transactions, values) first show payments are relatively well behaved through time and that the system does not contain a group of significant structural net receivers or payers among the participant institutions. Structural circular flows do, however, exist in the system, most prominently a large circular net flow between TARGET countries. Analysis of the properties of prominent network measures over time shows that fast network development takes place in the early phase of network formation of about one hour and slower development afterwards. The payment network is small (in actual nodes and links), compact (in path length and eccentricity) and sparse (in connectivity) for all time periods. In the long run, a mere 12% of the possible number of interbank connections is ever used and banks are on average only 2 steps apart. Relations in the network tend to be reciprocal. Our results also indicate that the network is susceptible to directed attacks. In a final section we show that the recent sub prime' turmoil in credit markets has not materially affected the network structure.

Virtual education is a concept which requires being debated for a long time, before being taken over or transformed according to your own principles or possibilities. The internet economy is strongly connected with its developing modalities. A society desiring to be developed must be initially educated, in order to understand the benefits of the new modality of social integration.

The United States now spends around $7 billion on universal service programs-subsidies intended to ensure that the entire country has access to telecommunications services. Most of this money supports telecommunications service in high cost (primarily rural) areas, and the High Cost fund is growing quickly. In response to this growth, policymakers are considering using reverse auctions, or bids for the minimum subsidy, as a way to reduce expenditures. While the U.S. has not yet distributed funds for universal service programs using reverse auctions, the method has been used widely. First, reverse auctions are akin to standard government procurement procedures, which call for firms to bid on government contracts to keep prices down. Sending contracts out for bid is common in both simple and complex government contracting. Second, many countries around the world have used reverse auctions for distributing universal funds. This paper reviews global experiences with reverse auctions and discusses their implications for the U.S. In particular, I review reverse auctions in Australia, Chile, Colombia, India, Nepal, and Peru. Not all of the auctions were successful, but they clearly demonstrate that reverse auctions can be an effective tool for revealing information about the true cost of providing universal coverage and for reducing expenditures on subsidies.

Private firms may not have efficient incentives to allow third-party producers to access their platform or develop extensions for their products. Based on a two-sided market model, I discuss two reasons for why. First, a private firm may not be able to internalize all benefits from cross-group externalities arising with third-party extensions. Second, firms may have strategic incentives to shut out third-parties because it relaxes competition.

Remedial or developmental courses are the most common instruments used to assist postsecondary students who are not ready for college-level coursework. However, despite its important role in higher education and substantial costs, there is little rigorous evidence on the effectiveness of college remediation on the outcomes of students. This study uses a detailed dataset to identify the causal effect of remediation on the outcomes of nearly 100,000 college students in Florida. Using a Regression Discontinuity design, we provide causal estimates while also investigating possible endogenous sorting around the policy cutoff. The results suggest math and reading remedial courses have mixed benefits. Being assigned to remediation appears to increase persistence to the second year and the total number of credits completed for students on the margin of passing out of the requirement, but it does not increase the completion of college-level credits or eventual degree completion. Taken together, the results suggest that remediation might promote early persistence in college, but it does not necessarily help students on the margin of passing the placement cutoff make long-term progress toward earning a degree.

Covert organizations are constantly faced with a tradeoff between secrecy and operational efficiency. Lindelauf, Borm and Hamers (2008) developed a theoretical framework to deter- mine optimal homogeneous networks taking the above mentioned considerations explicitly into account. In this paper this framework is put to the test by applying it to the 2002 Jemaah Islamiyah Bali bombing. It is found that most aspects of this covert network can be explained by the theoretical framework. Some interactions however provide a higher risk to the network than others. The theoretical framework on covert networks is extended to accommodate for such heterogeneous interactions. Given a network structure the optimal location of one risky interaction is established. It is shown that the pair of individuals in the organization that should conduct the interaction that presents the highest risk to the organization, is the pair that is the least connected to the remainder of the network. Furthermore, optimal networks given a single risky interaction are approximated and compared. When choosing among a path, star and ring graph it is found that for low order graphs the path graph is best. When increasing the order of graphs under consideration a transition occurs such that the star graph becomes best. It is found that the higher the risk a single interaction presents to the covert network the later this transition from path to star graph occurs.

Epinets presents a new way to think about social networks, which focuses on the knowledge that underlies our social interactions. Guiding readers through the web of beliefs that networked individuals have about each other and probing into what others think, this book illuminates the deeper character and influence of relationships among social network participants.Drawing on artificial intelligence, the philosophy of language, and epistemic game theory, Moldoveanu and Baum formulate a lexicon and array of conceptual tools that enable readers to explain, predict, and shape the fabric and behavior of social networks. With an innovative and strategically-minded look at the assumptions that enable and clog our networks, this book lays the groundwork for a leap forward in our understanding of human relations.
