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...

The impact of community-based family planning programs and access to credit on contraceptive use, fertility, and family size preferences has not been established conclusively in the literature. We provide additional evidence on the possible effect of such programs by describing the results of a randomized field experiment whose main purpose was to increase the use of contraceptive methods in ru...

Financial innovations are a common explanation for the rise in credit card debt and bankruptcies. To evaluate this story, we develop a simple model that incorporates two key frictions: asymmetric information about borrowers’ risk of default and a fixed cost of developing each contract lenders offer. Innovations that ameliorate asymmetric information or reduce this fixed cost have large extensiv...

The rural finance of China is still weak in the Chinese financial system. Without the support of the capital factor, the new rural construction of socialism could not be realized, but the investment of the capital factor and the enhancement of the humanistic morality must be based on the good credit information resource. The rural financial departments should fully support the construction of t...

Tt is widely believed that closed-loop per-VC flow control is needed to effectively deal with congestion for ABR traffic in ATM networks. The many ATM flow control mechanisms that have been proposed can be divided in two classes. A first class consists of roundtrip-based rate control algorithms in which a source selects a transmit rate for each VC, based on feedback from the switches along its ...

As link speeds increase in datacenter networks, existing congestion control algorithms become less effective in providing fast convergence. TCP-based algorithms that probe for bandwidth take a long time to reach the fair-share and lead to long flow completion times. An ideal congestion control algorithms for datacenter must provide 1) zero data loss, 2) fast convergence, and 3) low buffer occup...

Abstract In this paper we provide a stock price model that explicitly incorporates credit risk, under stochastic optimal control system. The also the managerial of risk through policy in We explicit conditions on existence feedback controls for with risk. prove continuity value function, and then dynamic programming principle our Finally, Viscosity Solution Hamilton–Jacobi–Bellman equation. Thi...

The article proposes a model of credit risk assessment on the basis of factor analysis of retail clients / borrowers in order to ensure predictive control of the level of risk posed by potential clients in commercial banks engaged in consumer lending. The aim of the study is to determine the level of risk represented by different groups (classes) of retail clients (borrowers) in order to reduce...
