    ABSTRACT We use primary data from Bangladesh to examine whether the strength of bank-borrower relationships affects the process of transition from joint liability to individual liability loans in the microcredit sector. Using instrumental variables in survival analysis, we show that borrowers who maintain a non-mandatory savings account with the microfinance institution (MFI), and those who borrow from a single MFI, graduate from joint liability to individual liability loans with relatively short repayment records. The results are robust across a range of non-parametric and parametric specifications. Our findings imply that MFIs have incentives to invest in relationship development with their clients in order to expedite the process of transition from joint liability to individual liability loans, which in turn, can reduce the incidence of voluntary drop outs by the matured borrowers.

    Abstract Prefix delegation-based schemes have been proposed to solve the route optimization problem in NEtwork MObility where multiple IP-enabled hosts move together as a mobile network. Differences in the route optimization for hosts at the cost of increased signaling will result in performance difference of the schemes depending on parameters, such as speed of the mobile network, its distance from the home network (the network to which mobile network usually belongs), and the number of hosts in the mobile network. ...

    Among the schemes, proposed in the literature to solve the route optimization problem in NEtwork Mobility (NEMO), the prefix delegation-based schemes perform better than other schemes. Depending on the way the prefix are delegated, the prefix delegation-based schemes result in difference in performance under different speed at various distance from the home network (network to which mobile network usually belongs). Therefore, there is a need to evaluate the performance of individual prefix delegation-based scheme to find ...
