TL;DR: In this article, a general class of empirical statistics, including generalized empirical exponential family likelihood statistics, generalized empirical likelihood statistics and empirical statistics arising from Bayesian considerations, and Bartlett-type adjusted versions of ED statistics, are investigated.
Abstract: We consider a very general class of empirical statistics that includes (a) empirical discrepancy (ED) statistics, (b) generalized empirical exponential family likelihood statistics, (c) generalized empirical likelihood statistics, (d) empirical statistics arising from Bayesian considerations, and (e) Bartlett-type adjusted versions of ED statistics. With reference to this general class, we investigate higher order asymptotics on power and expected lengths of confidence intervals. For (b)-(e), such results have been hitherto unexplored. Furthermore, our findings help in understanding the presently known results on the subclass (a) from a wider perspective.

01 Jan 2015TL;DR: This paper employs cases of e-Government projects to demonstrate the framework proposed and demonstrates how this classification can act as a handle for deciding on certain important aspects of project management.
Abstract: The extant literature on management of e-Government projects discusses success factors in detail. However, it is observed that the contingency aspects of management of these projects have not been given sufficient attention. The classification of e-Government projects based on specific project attributes is an area where the current understanding is rather inadequate. The relationship between certain eGovernment project attributes and different management strategies has also not been explored adequately. In this paper, we examine the impact of two important project attributes on certain important aspects of project management. This paper employs cases of e-Government projects to demonstrate the framework so developed. A classification of such projects based on the mandatory/optional nature of concerned service and the mandatory/optional nature of intermediaries - two important project attributes - has been proposed. We have also demonstrated how this classification can act as a handle for deciding on certain important aspects of project management.

TL;DR: This article shows somewhat surprisingly that, following a cyber-attack, the effect of a network interconnection topology and a wide range of loss distributions on the probability of a Cyber-blackout and the increase in total service-related monetary losses across all organizations are mostly very small.
Abstract: Service liability interconnections among globally networked IT- and IoT-driven service organizations create potential channels for cascading service disruptions worth billions of dollars, due to modern cyber-crimes such as DDoS, APT, and ransomware attacks. A natural question that arises in this context is: What is the likelihood of a cyber-blackout?, where the latter term is defined as the probability that all (or a major subset of) organizations in a service chain become dysfunctional in a certain manner due to a cyber-attack at some or all points in the chain. The answer to this question has major implications to risk management businesses such as cyber-insurance when it comes to designing policies by risk-averse insurers for providing coverage to clients in the aftermath of such catastrophic network events. In this article, we investigate this question in general as a function of service chain networks and different cyber-loss distribution types. We show somewhat surprisingly (and discuss the potential practical implications) that, following a cyber-attack, the effect of (a) a network interconnection topology and (b) a wide range of loss distributions on the probability of a cyber-blackout and the increase in total service-related monetary losses across all organizations are mostly very small. The primary rationale behind these results are attributed to degrees of heterogeneity in the revenue base among organizations and the Increasing Failure Rate property of popular (i.i.d/non-i.i.d) loss distributions, i.e., log-concave cyber-loss distributions. The result will enable risk-averse cyber-risk managers to safely infer the impact of cyber-attacks in a worst-case network and distribution oblivious setting.

TL;DR: In this paper, the authors examined the degree of efficiency of Indian ADRs and their underlying stocks trading in NSE/BSE from an adaptive markets hypothesis (AMH) perspective that is theoretically grounded in nonlinear serial dependence.
Abstract: This paper examines the degree of efficiency of Indian ADRs and their underlying stocks trading in NSE/BSE from an adaptive markets hypothesis (AMH) perspective that is theoretically grounded in nonlinear serial dependence. For this purpose, the authors employ the windowed as well as the rolling hinich bicorrelation test procedures on ADRs and the underlying stocks issued by Indian firms such as, and limited to, Dr. Reddy’s Laboratories, HDFC Bank, ICICI Bank, Infosys, Wipro, Tata Motors, and Sterlite Industries. The study’s findings indicate that the degree of market efficiency witnessed at the level of individual scrips (ADRs or underlying domestic stocks) differs considerably from the degree of efficiency of the broader stock market in which such scrips trade. Further, the degree of efficiency witnessed amidst all US and Indian scrips considered for this study was found to be heterogeneous in nature and in-turn warrants a ranking approach. Lastly, the degree of efficiency witnessed in certain (not all) dually-listed Indian scrips was found to be homogenous across trading locations. However, this does not happen to be the case for all other dually-listed scrips considered for this study. The study’s findings bring to light the need for disaggregated, firm level market efficiency studies aimed at examining firm-level market efficiency at different trading locations and in-turn identifying the antecedents behind homogeneity (or lack-thereof) in firm-level market efficiency across multiple trading locations.
