The standard intertemporal model of open economy with a dynamic budget constraint predicts that investment and saving should be cointegrated as long as the economy does not violate its budget constraint. Recent empirical studies of the long run investment-saving comovement for the 1947:1–1987:3 period US data, however, report conflicting findings: some studies find that the time series of inves...

An augmented Lagrangian (AL) can convert a constrained optimization problem into a sequence of simpler (e.g., unconstrained) problems, which are then usually solved with local solvers. Recently, surrogate-based Bayesian optimization (BO) sub-solvers have been successfully deployed in the AL framework for a more global search in the presence of inequality constraints; however, a drawback was tha...

Data envelopment analysis (DEA) mainly utilizes envelopment technology to replace production function in microeconomics. The input and output of decision making units (DMUs) are projected into the attributes to evaluate or measure their performance. However, if the inputs and outputs are linguistically termed or are fuzzy-numbered, conventional DEA can not easily measure the performance. Theref...

Increasing the amount of buffering for MPI sends is an effective way to improve the performance of MPI programs. However, for programs containing non-deterministic operations, this can result in new deadlocks or other safety assertion violations. Previous work did not provide any characterization of the space of slack elastic programs: those for which buffering can be safely added. In this pape...

To solve computationally expensive problems, multiple processor SoCs (MPSoCs) are frequently used. Mapping of applications to MPSoC architectures and scheduling of tasks are key problems in system level design of embedded systems. In this paper, a cluster slack optimization algorithm is described, in which the tasks in a cluster are simultaneously mapped and scheduled for heterogeneous MPSoC ar...

This paper presents the idea of managing the comprising computations of an application performed by an embedded networked system. An efficient algorithm for exploiting the timing slack of building blocks of the application is proposed. The slack of blocks can be utilized by replacing them with slower but cheaper, i.e. better, modules and by assigning the computations to the proper resources. Th...

Bank of Japan May 2011 The earthquake that struck Japan in March 2011 has reduced the supply capacity of the economy, which works in the direction of tightening the output gap. At the same time, however, if weak household and corporate sentiment lead to a decline in aggregate demand, this will work in the direction of increasing the slack in the economy. Moreover, developments in supply and dem...

Most of the corporate governance literature rests on a premise that the interests of various stakeholder groups conflict and that managerial loyalty is more likely to be captured by shareholders than any other constituency. Yet, stakeholder interests do converge in the objective of controlling managerial slack and non-equity constituents have substantial influence over firm decisions. Although ...

This paper is aimed to give an illustration on the application of Data Envelopment Analysis (DEA) as a tool to assess Quality Management (QM) efficiency. A variant of DEA, slack based measure (SBM) is used for this purpose. From this study, it is found that DEA is suitable to measure QM efficiency and give improvement suggestions to the inefficient QM. Keywords—Quality Management, Data Envelopm...
