Risk-based capital adequacy requirements are the main tool employed by government regulators to assure bank stability. This approach allows banks to choose from a number of alternative methods for calculating the required capital. Many systems for measuring risk differ significantly in cost, precision, and in the potential “capital savings”. We develop a statistical model for evaluating risk me...

In this paper, we reexamine the question “Why doesn’t capital ‡ow from rich to poor countries?” posed, most recently, by Lucas (1990). We build a simple contracting framework where costly intermediation together with an adverse selection problem have quantitatively important e¤ects on capital ‡ows. When intermediation costs are ignored, the model behaves much like the neoclassical model in term...

This paper explains the BEA methodology for computing historical cost and replacement cost measures of the net stock of capital in the U.S. economy. It is demonstrated that there exists a threshold rate of inflation in the price of capital goods that keeps the percentage difference between the two capital stock measures constant. Hence, over periods when average inflation in the price index for...

In this research study, energy, exergy and economic analyses is performed for a combined cycle power plant (CCPP) with a supplementary firing system. The purpose of this analyses is to evaluate the economic feasibility of a CCPP by applying an optimization techniques based on Evolutionary algorithms. Actually, the evolutionary algorithms of Firefly, PSO and NSGA-II are applied to minimize the c...

A regulator resolving a bank faces two audiences: depositors, who may run if they believe the regulator will not provide capital, and banks, which may take excess risk if they believe the regulator will provide capital. When the regulator’s cost of injecting capital is private information, it manages expectations by using costly signals: (i) A regulator with a low cost of injecting capital may ...

Optimal design of high-speed valve trains requires the use of an accurate analytical model. While the governing differential equations are important, the coefficients (or parameters) used in these equations are equally as important. Since many of the parameters used in valve train models are difficult to measure directly, parameter identification based on experimental data is required to assure...

The cost of public investment is not the value of public capital. Unlike with private investors, there is no plausible behavioral model in which every dollar that the public sector spends as “investment” creates capital in an economic sense. While this simple analytic point is obvious, it has so far been uniformly ignored in the empirical literature on economic growth which uses, at best, cumul...

in this paper we have proposed an approach for emotion detection in implicit texts. we have introduced a combinational system based on three subsystems. each one analyzes input data from a different aspect and produces an emotion label as output. the first subsystem is a machine learning method. the second one is a statistical approach based on vector space model (vsm) and the last one is a key...

sedimentation is one of the most important problems in harbors that results in considerable economic costs. harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. in the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...
