Estimation of the mean of the selected population under asymmetric loss function

This paper is concerned with the comparison of seven estimators of the mean of the selected population from two normal populations with unknown means and common known variance under an asymmetric loss namely the LINEX loss function. The proposed estimators are invariant under location transformation. The bias and risks of the seven estimators are computed and compared. The conclusion recommend the use of δ_P (σ) which is simple to use and it is minimax. Received: January 1999     

Are good financial advisors really good? The performance of investment banks in the M&;A market

The study examines whether prestigious investment banks deliver quality gains to their clients in a sample of 6,379 US M&A deals. It finds that acquirers advised by tier-one advisors lost more than $42 billion, whereas those advised by tier-two advisors gained $42 billion, whereas those advised by tier-two advisors gained 13.5 billion at the merger announcement. The results were mainly driven by the large loss deals advised by tier-one advisors. The evidence indicates that investment banks might have different incentives when they advise on large deals vs. small deals. The results imply that market share based reputation league tables, could be misleading and therefore, the selection of investment banks should be based on their track record in generating gains to their clients. The findings were consistent with the superior deal hypothesis as tier-one target advisors outperformed tier-two advisors and the existence of a prestigious advisor on at least one side of an M&A transaction resulted in higher wealth gains to the combined entity. Target advisors were able to extract more wealth gains for their clients, which led to higher combined gains at the expense of the acquirer.     

Take it or leave it: Using regulatory fit theory to understand reward redemption in channel reward programs

Channel Reward Programs (CRPs) facilitate relationship management within reseller networks in distribution channels, yet a persistent problem is that rewards are not seen as valuable, which can reduce program investment. By applying Regulatory Fit theory, to understand how to sustain goal orientation (promotion or prevention) and stimulate task engagement through a match with the manner of goal pursuit, this study demonstrates that the presentation style suppliers adopt influences resellers' perceptions of reward value and their rate of point redemption with respect to CRPs. Two field studies demonstrate the mechanisms driving this effect. First, fit effects result from the interaction between reward type and presentation format (i.e., verbal vs. numerical) and affect perceived reward values and investment decisions. Second, cognitive engagement and “feeling right” about reward redemption mediate the effects of fit on investment opportunity evaluations. In turn, the findings demonstrate that CRP efficacy can be enhanced by stimulating regulatory orientations that match the presentation formats of the reward and that the dual affective–cognitive processes affect probabilistic judgments of rewards. This additional mechanism can further stimulate resellers' engagement with and investment in CRPs within complex decision-making contexts.     

Entrepreneurial Characteristics,Motives, and Business Challenges: Exploratory Study of Small- and Medium-Sized Hotel Businesses

ABSTRACT

The purpose of this study is to gather information about the determinants and characteristics of the owners/managers of small- and medium-sized hotels (SMSHs) and identify various issues in starting up and operating businesses in the United Arab Emirates. The results of this study reveal that the majority of the owners/managers of SMSHs in the United Arab Emirates are male, young and middle age, and relatively new to the tourism industry. The motivations for the business ventures of the entrepreneurs include wanting to be financially independent, become one’s own boss, involvement in family business and the opportunities of the hotel business. Among the key business challenges highlighted by the owners/managers of SMSHs are stiff competition in the hotel industry, increased operating costs, reduced demand, and lack of skilled employees. Several key strategies have been employed to face these challenges. These include offering competitive pricing, improving the marketing and channels of promotion, enhancing the quality of service and providing superior customer service.     

Import-content of exports and J-curve effect

This article investigates how the response to devaluation of trade balance is affected, compared to J-curve hypothesis, by the presence of imported inputs in the production of exports. Using first the Almon lag technique and then the cointegration and the generalized impulse response function analysis, the J-curve effect is examined in two sectors of Turkish economy (manufacturing and mining), which use imported inputs at different rates. Based on the data covering the period from the first quarter of 1986 to the third quarter of 1998, our results indicate that in neither sector J-curve exists and that the violation of the J-curve effect is more severe in the sector with higher import content     

On the advantages of economically designed variable sample sizes and sampling intervals T2 control chart: double warning lines scheme

Faraz and Parsian (Stat Pap 47:569–593, 2006) have shown that the double warning lines (DWL) scheme detects process shifts more quickly than the other variable ratio sampling schemes such as variable sample sizes (VSS), variable sampling intervals (VSI) and variable sample sizes and sampling intervals (VSSVSI). In this paper, the DWL T² control chart for monitoring the process mean vector is economically designed. The cost model proposed by Costa and Rahim (J Appl Stat 28:875–885, 2001) is used here and is minimized through a genetic algorithm (GA) approach. Then the effects of the model parameters on the chart parameters and resulting operating loss is studied and finally a comparison between all possible variable ratio sampling (VRS) schemes are made to choose the best option economically.     

A model for total quality management in higher education

Total quality management (TQM) is widely recognised as a management philosophy for improving customer satisfaction and organisational performance. However, there is no consensus over the critical success factors of TQM, in particular, in higher education (HE) and developing countries. Literature shows mixed results on the success and applicability of TQM principles in education, thus, underlining the need to revisit the application of TQM principles in HE. This paper identifies the critical success factors of TQM in Pakistani universities. Data was collected from faculty members of universities through questionnaires. The findings reveal that ‘leadership’, ‘vision’, ‘measurement and analysis’, ‘process control and evaluation’, ‘programs design and resources allocation’ and ‘stakeholder focus’ emerge as the critical success factors of TQM in HE. The findings have implications at macro, meso, and micro levels of HE.     

Monetary Policy in the Industrial World: Reflections on some Basic Issues

Abstract

This paper is a general assessment of monetary policy in major OECD countries during the 1990s. Within a simple policy framework that combines money growth, nominal income, and an open economy IS-LM type Mundell-Fleming model, the paper discusses the major strands in the conduct of monetary policy in developed industrial economies. It throws light on such problems as “rules versus discretion”, management of exchange rates, the effect of monetary changes on income and prices, and the rupture of monetary policy with other instruments of economic policy that also affect the economy.     

The Effect of Exchange Rate on Bilateral Trade Balance: New Evidence from Malaysia and Thailand

This paper attempts to identify the major economic factors that influence the bilateral trade balances of Malaysia and Thailand with the US and Japan. To this end, an unrestricted VAR model was estimated using quarterly frequency data from 1980: I to 1996: IV. The Johansen results indicate a stable long-run relation between trade and three macro variables: exchange rate, domestic income and foreign income. The main findings of this paper are: (i) the real effective exchange rate is an important variable in the trade balance equation and devaluation improves the trade balances of both economies in the long-run; (ii) the other important variables that determine trade balance include domestic and foreign incomes; (iii) the results indicate no J-curve effect and causal run from exchange rate to trade balance, (iv) the real effects of devaluation are distributed over a period of eight to nine quarters.
