Interest rate determination in India: domestic and external factors

This paper examines the determinants of interest rates in India in the post-reform period in the context of a model that takes into account both domestic and external factors. The short- and long-run behavior of interest rates (commercial paper rate, 3-month Treasury bill rate, 12-month Treasury bill rate) is studied. The empirical results are robust across interest rates and indicate the existence of a cointegrating relationship between real interest rates, real government expenditure, real money supply, foreign interest rates and the forward premium. The estimations also show that movements in interest rates are Granger caused by both domestic and external factors.

Distribution-free tests for independence against positive quadrant dependence: A generalization

A class of distribution-free tests based on two matched pairs is considered for testing independence against positive quadrant dependence. The class of tests proposed by Kochar and Gupta (1990) is a member of the proposed class. The performance of the proposed class is evaluated in terms of Pitman asymptotic relative efficiency for Block-Basu (1974) model and Woodworth family of distributions. The small sample performance of few members of the proposed class is also studied by finding empirical powers. Unbiasedness and consistency of the proposed class of tests have been established.     

Participant Supervision: Supervisor and Supervisee Experiences of Cotherapy

Participant supervision is a unique application of live supervision in which a supervisor and supervisee see clients conjointly. Although minimally discussed in the family therapy literature, it has notable advantages, chief among them being a shared clinical experience that increases attunement to supervisee skill and development, the modeling of skillful intervention, and a higher degree of collegiality. However, it is not without its challenges, including supervisee vulnerability and anxiety, diffusion of responsibility, and limited time for case discussion. This article highlights the experience of one supervisor and three doctoral‐level supervisees engaging in participant supervision over the course of a 2‐year period. Using illustrative examples, we discuss our experience of the advantages and challenges of participant supervision, and provide recommendations for establishing a collaborative relational context within which supervisory benefits can be maximized.     

On testing exponentiality against new better than used of specified age

R.M. Hollander, D.H. Park and F. Proschan [A class of life distributions for aging, J. Amer. Statist. Assoc. 81 (1986) 91–95] introduced the concept of the larger class of life distributions called new better than used of specified age. In practice, one might be interested in the new better than used behaviour at an unknown but estimable age t₀. Here, we investigate the testing of new better than used of specified age t₀ (NBU-t₀) alternatives. A class of test statistics for testing NBU-t₀ (t₀ is known) based on a U-statistic whose kernel depends on sub-sample minima is proposed. A member of the class of tests proposed by N. Ebrahimi and M. Habbibullah [Testing whether the survival distribution is new better than used of specified age, Biometrika 77 (1990) 212–215] for this problem belongs to the class of tests proposed here. The distributional properties of the class of test statistics are studied. The performances of a few members of the proposed class of tests are studied in terms of Pitman asymptotic relative efficiency. The Pitman ARE values show that the members of the class perform well in comparison with the N. Ebrahimi and M. Habbibullah [Testing whether the survival distribution is new better than used of specified age, Biometrika 77 (1990) 212–215] tests. The proposed class of tests is shown to be consistent for NBU-t₀ alternatives.     

Market channel selections by US nursery plant producers: a multivariate nonparametric fractional regression analysis

Availability of market channel alternatives has helped the growth of ornamental plant sales in the United States. To identify the factors affecting the choice and allocation of outputs to different market channels by nursery producers, we first use a mixture of experts model to select clusters of homogenous subpopulations of US nursery producers based on a 2009 National Nursery Survey. The impact of growers’ business characteristics on shares of sales to these channels was estimated using multivariate parametric and nonparametric fractional regression models. Specification tests indicated a nonparametric model was superior to a parametric model in some clusters. Important explanatory variables affecting the sales volume to different channels were sales of plant groups, kinds of contract sales, promotional expenses, and farm size. Results indicated the existence of clear market segmentation of nursery producers in the United States.     

On a new distribution arising in decaying inventory systems

This paper considers the number of de~ands for a good item during a cycle of an inventory system with initial stock Q and with the items in stock deteriorating stochastically over time. The demands occur as a Poisson process, and the lot is replenished with zero lead time, making the cycle time itself a random variable. The probability distribution of the number of demands is developed; also tabulated is the minimal reorder quantity Q(k,δ) to assure meeting a minimum of k demands in a cycle with a confidence of (1-δ) .     

Social media led co-creation of knowledge in developing societies: SME’s roles in the adoption,use and appropriation of smartphones in South Asia

Abstract

Social media supports the creative economy through its involvement in the adoption and appropriation of new innovation and accelerates economic growth. The current paper expands on this notion by identifying and analyzing the interaction between social media-based communities and small and medium enterprises (SMEs), as it examines how social media contributes to the knowledge co-creation and supports the adoption, use and appropriation of smartphones in South Asian countries, which are inhabited by approximately 1.6 billion people. The findings obtained through virtual ethnography (VE) provide insights into the dynamics and kinetics of knowledge co-creation and how that benefits large multinationals, small local businesses and consumers in developing societies. As such, we advance the knowledge management scholarship by presenting a holistic model of co-creation of knowledge involving multiple stakeholders.
