Defective capital assets may be quickly restored to their operational condition by replacing the item that has failed. The item that is replaced is called the Line Replaceable Unit (LRU), and the so-called LRU definition problem is the problem of deciding on which item to replace upon each type of failure: when a replacement action is required in the field, service engineers can either replace ...

Aims: This paper examines the performance of commercial banks in Taiwan, in terms of their ability to provide maximum outputs by the given input utilization. There seems to be important concern hanging on the ability of commercial banks to provide output-base for the available input utilization in Taiwan. Study Design: This study has been divided into four parts to investigate the DEA model suc...

We examine how the criteria for choosing estimation samples (peer firms) affect the ability to detect discretionary accruals, using several variants of the Jones (1991) model. Researchers commonly estimate accruals models in cross-section, and define the estimation sample as all firms in the same industry. We examine whether firm size performs at least as well as industry membership as the crit...

This work extends the contagion model introduced by Nier et al. (2007) to inhomogeneous networks. We preserve the convenient description of a financial system by a sparsely parameterized random graph but add several relevant inhomogeneities, namely well-connected banks, financial institutions with disproportionately large interbank assets, and big banks focusing on wholesale and retail customer...

Quantitative portfolio allocation requires the accurate and tractable estimation of covariances between a large number of assets, whose histories can greatly vary in length. Such data are said to follow a monotone missingness pattern, under which the likelihood has a convenient factorization. Upon further assuming that asset returns are multivariate normally distributed, with histories at least...

This paper describes the Italian real estate investment funds industry, providing an overview of the distinctive features and risk factors of this sector. By using accounting and supervisory data, we: (1) compute the returns of the real estate assets in the portfolio of these funds; (2) construct a price index and a total return index of the real estate assets held by the Italian funds; (3) def...

In this work, we present a proof-of-concept Automated Asset Locating System (AALS) for enhancing inventory management. AALS integrates LIDAR and RFID sensor measurements into a Rao-Blackwellized particle filter for simultaneously localizing its pose with the positions of assets in the environment. We present significant experimental results where the proof-of-concept system successfully travele...

It is now well established that the volatility of asset returns is time varying and highly persistent. One leading model that is used to represent these features of the data is the stochastic volatility model. The researcher may test for non-stationarity of the volatility process by testing for a unit root in the log-squared time series. This strategy for inference has many advantages, but is n...
