E-cash algorithms offer strong protection on principal anonymity, transaction authenticity and quota enforcement of credit dispense but as of now there is no study on how to integrate them with the resource allocation schemes. In this paper, we propose a hypercube based tracking system for both credit dispense and resource allocation of computing assets using E-cash algorithms. Hypercube is cho...

Access to credit markets is generally considered a hallmark of developed economies. In the United States, most households appear to have substantial ability to borrow; indeed, households in the United States have an average of over $23,000 in nonmortgage debt alone. Nevertheless, economists often point to limited borrowing opportunities for lower-income households to explain anomalous findings ...

T he Internet gives vendors an easy way to set up shop for electronic commerce throughout the world. In an extension of mailand phone-order transactions, customers usually pay for e-commerce goods and services through a credit card. The transmission of credit card numbers requires vendor sites to support encryption through the Secure Sockets Layer1 or Transport Layer Security2 protocols. SSL ca...

a r t i c l e i n f o Paying particular attention to the degree of banking market concentration in developing countries, this paper examines the effect of credit information sharing on bank lending. Using bank-level data from African countries over the period 2004 to 2009 and a dynamic two-step system generalised method of moments (GMM) estimation , it is found that credit information sharing i...

The expansion of the electronic commerce, together with an increasing confidence of customers in electronic payments, makes of fraud detection a critical factor. Detecting frauds in (nearly) real time setting demands the design and the implementation of scalable learning techniques able to ingest and analyse massive amounts of streaming data. Recent advances in analytics and the availability of...

This paper provides, and empirically estimates, a structural model of sovereign default risk on external debt. The sovereign endogenously determines its level of foreign debt and default policy. Consistent with default crisis episodes, the sovereign and its lenders bargain at default over a reduction of the debt service. The potential for debt restructuring o¤ers the sovereign greater incentive...

The paper considers a general approach for classifying objects using mathematical programming algorithms. The approach is based on optimizing a utility function, which is quadratic in indicator parameters and is linear in control parameters (which need to be identified). Qualitative characteristics of the utility function, such as monotonicity in some variables, are included using additional co...

This paper provides an economic assessment of export credit guarantee commitments by the Austrian export credit agency, using firm-level data on a cross-section of 178 Austrian exporting firms for the year 2008. In a first step, we estimate the relative importance of various determinants of export guarantee usage. Results suggest that the most crucial determinants are: firm size, whether or not...

A systematic cross-country analysis of e-commerce activity reveals that although physical infrastructure explains much of the variation in basic Internet use, e-commerce activity also depends significantly on the "rule of law" and, secondarily, on availability of credible payment channels such as credit cards. These results suggest that an institutional environment that facilitates the building...
