On stochastic comparisons of minimum order statistics from the location–scale family of distributions

We consider stochastic comparisons of minimum order statistics from the location–scale family of distributions that contain most of the popular lifetime distributions. Under certain assumptions, we show that the minimum order statistic of one set of random variables dominates that of another set of random variables with respect to different stochastic orders. Furthermore, we illustrate our results using some well-known specific distributions.     

Property Condition Disclosure Law: Why Did States Mandate ‘Seller Tell All’?

Thirty-four US states have already enacted some form of seller’s Property Condition Disclosure Law. At a time when there is a movement in this direction nationally, this paper attempts to ascertain the factors that lead states to adopt disclosure law. Motivation for the study stems from the fact that not all states have yet adopted the law, and states that have enacted the law have done so in different years. The analytical structure employs hazard models, using a unique set of economic and institutional attributes for a panel of 50 US States spanning 21 years, from 1984 to 2004. The proportional hazard analysis of law adoption reveals that greater number of disciplinary actions tends to favor passage of the law. Greater broker supervision, implying generally higher awareness among real estate agents, seems to have a negative impact on the likelihood of a state adopting a Property Condition Disclosure Law.

Multimarket trading and market liquidity

When a security trades at multiple locations simultaneously,an informed trader has several avenues in which to exploit hisprivate information. The greater the proportion of liquiditytrading by 'large' traders who can split their trades acrossmarkets, the larger is the correlation between volume in differentmarkets and the smaller is the informativeness of prices. Weshow that one of the markets emerges as the dominant locationfor trading in that security. When informed traders can usetheir information for more than one trading period, the timelyrelease of price information by market informed traders expectto make subsequently at other locations. Markets makers, competingto offer the lowest cost of trading at their location, consequentlydeter informal trading by voluntarily making the price informationpublic and by 'cracking down' on insider trading.     

Taking stock or cashing in? Shareholder style preferences,premiums and the method of payment

We develop and test hypotheses on the impact of target shareholders' investment style preferences on the method of payment and premiums in acquisitions. Stock offers (unlike cash offers) allow target shareholders to defer capital gains taxes. This deferral value, however, depends on target shareholders' willingness to retain acquirer stock. The empirical findings support our hypotheses. Bid premiums in stock offers are negatively and jointly related to target shareholder tax liabilities and to variables proxying for target shareholder willingness to hold acquirer stock. Moreover, the difference between predicted cash and stock premiums due to these factors significantly explains the method of payment choice.     

Private Label Vendor Selection in a Supply Chain: Quality and Clientele Effects

We model a supply chain consisting of a national brand manufacturer and an independent manufacturer, both of whom are potential suppliers of store brand to a single retailer. The retailer serves two customer segments—a quality sensitive segment (high type) and a price sensitive (low type) segment. The retailer serves these two segments by targeting the national and store brands to the quality and price sensitive segments, respectively. When the national brand manufacturer supplies the store brand he internalizes the effect of store brand quality on the national brand's retail prices. This leads the national brand manufacturer to choose a lower store brand quality than the independent manufacturer. This decrease in store brand quality has the benefit of increased revenues from the high type customers along with an associated cost of decreased revenues from the low type customers. Thus, when the benefit outweighs the cost the retailer chooses the national brand manufacturer to supply the store brand. We show that the retailer will choose the national brand manufacturer to supply the store brand when (a) the size of the high type customer segment is large relative to the low type customer segment, (b) the valuations of the high type customer segment is large relative to the low type customer segment, and (c) the retailer's margin requirement on the store brand is not very high. Overall, these results suggest that retailers who serve a bigger sized quality (price) sensitive clientele would have the national brand (independent) manufacturer supply the store brand.     

Shannon's Entropy and Its Generalisations Towards Statistical Inference in Last Seven Decades

Starting from the pioneering works of Shannon and Weiner in 1948, a plethora of works have been reported on entropy in different directions. Entropy‐related review work in the direction of statistical inference, to the best of our knowledge, has not been reported so far. Here, we have tried to collect all possible works in this direction during the last seven decades so that people interested in entropy, specially the new researchers, get benefited.     

Macroeconomic impacts of remittances in Bangladesh: The role of reverse flows

Das and Serieux (2010; 2015) and Serieux (2011) used the term “reverse flows” to define the part of external resources that is not domestically absorbed; instead used to finance debt obligations, capital flight, and accumulate reserves. While there is a vast literature on the growth and development impact of remittances in developing countries, the existing empirical literature has mostly ignored the potential diversion of remittances to reverse flows. This paper bridges the gap in the literature by estimating the reverse flows in the case of Bangladesh, which is one of the top remittance recipient countries in the world. The data set runs from 1976 to 2015. Econometric results obtained by employing the Autoregressive Distributed Lag (ARDL) approach show that almost 13–14% of remittances (as the ratio of gross domestic product, GDP) are diverted to finance reverse flows. In other words, the effects of remittances (as the ratio of GDP) on consumption and investment rates are no more than 86–87%. Therefore, the underlying assumption made in the existing literature that all remittances are used to increase consumption and/or investment overstates the impact of this external resource flow in Bangladesh. Findings from this study have important policy implications not only for Bangladesh but for other remittance recipient developing countries. Our findings will help the government to design policies to ensure the optimum allocation of remittances in the domestic economy.     

Regulation and Systematic Risk in the Electric Utility Industry: A Test of the Buffering Hypothesis

In this paper, the authors test Peltzman's [19] buffering hypothesis—whether regulatory environment impacts systematic risk for regulated electric utilities. The paper differs from previous research in that an exogenously defined measure of regulatory environment, a large sample, and a method that controls for time-series and crosssectional autocorrelation are used. The results are consistent with the buffering hypothesis but only in years of increasing input factor prices for the utilities. Using causality tests, the results also show that it is the regulatory environment that influences systematic risk and not vice versa.     

overview of OR techniques for airline revenue management

With the increasing interest in decision support systems and the continuous advance of computer science, revenue management is a discipline which has received a great deal of interest in recent years. Although revenue management has seen many new applications throughout the years, the main focus of research continues to be the airline industry. Ever since LITTLEWOOD (1972) first proposed a solution method for the airline revenue management problem, a variety of solution methods have been introduced. In this paper we give an overview of the solution methods presented throughout the literature.     

Development and application of the Leadership Archetype Questionnaire

The leadership assessment questionnaire (LAQ) is a 360 degree survey instrument designed to help organizational leaders identify their own style of leadership and formulate appropriate development objectives. It is designed to provide avenues for development of an executive team in which multiple leadership archetypes are represented. The LAQ is based on eight leadership archetypes – strategist, change-catalyst, transactor, builder, innovator, processor, coach, and communicator. These archetypes are representations of ways of leading in a complex organizational environment. In this article, we discuss the development, design, and psychometric analysis of the LAQ. We detail the conceptual foundations of the questionnaire and the psychometric methods used to confirm the validity and reliability of the instrument. We conclude with avenues for future research.
