Multi-attribute analysis of confidence,convenience and price functions of customers of financial services firms: A GLS systems model

The paper examines attributes of customers for modelling the dimensions of confidence, convenience and affordability of services offered by financial services firms (FSFs) by applying a generalised least square (GLS) systems model to a cross-section of customers in Dubai. These three dimensions have become major drivers of long-run viability and survivability in the last 15–20 years, because of dynamic and competitive macroeconomic forces faced by the FSFs. Earnings stability, longevity of relationship and liquidity attributes significantly explain the confidence level of customers across FSFs. Core, tangible and relational attributes besides ambience and ATM network, positively significantly explained the convenience level of customers in FSFs. Home loans, credit cards, savings accounts, term deposits and insurance services are significant products that are affordable and valued by customers. The systems model was validated using a holdout sample. The study findings have implications for customer relationship management, customer insight and production/transaction processing competencies of FSFs in the study area and are equally applicable to FSFs in other developed and developing economies.     

Models of Multi-Category Choice Behavior

Given the advent of basket-level purchasing data of households, choice modelers are actively engaged in the development of statistical and econometric models of multi-category choice behavior of households. This paper reviews current developments in this area of research, discussing the modeling methodologies that have been used, the empirical findings that have emerged so far, and directions for future research. We also motivate the use of Bayesian methods to overcome the computational challenges involved in estimation.     

On Measuring the Quality of Survey Estimates

The quality of survey estimates is directly affected by survey errors that include sampling errors due to selecting a sample rather than the whole population, and non-sampling errors arising from data collection and processing procedures. The latter include frame error, measurement error and non-response. This paper addresses design issues related to total survey error and its components. Methods for handling frame problems and non-response are also presented.

Revisiting the Link Between Stock Prices and Goods Prices in OECD Countries

Fisher hypothesis postulates positive relation between stock return and inflation; however early studies document negative relationship between the two and they conclude that stock cannot be used as a hedge against inflation. In this paper we explore long‐run nonlinear relationship between stock price and goods price. Our sample consists of 19 OECD countries; all or some of these countries have been studied before with the findings of linear cointegration between the stock index and goods price index. Based on unit root tests and linear cointegration test, we apply threshold cointegration tests, Autoregressive Distributed Lag (ARDL) cointegration test and panel VAR method. With all these econometric methods we arrive at heterogeneous findings as follows: two countries have linear cointegration, five countries have threshold cointegration, nine countries do not have any cointegration and finally two countries provide inconclusive results. Estimates of Fisher coefficient provided by linear and nonlinear cointegration methods, which range between 1.27 and 1.86, are consistent with previous studies. Impulse response analysis from panel VAR for countries having no cointegrating relation shows that shock to inflation produces negative response in stock return, which supports findings of earlier studies.     

Inferring Market Structure from Customer Response to Competing and Complementary Products

We consider customer influences on market structure, arguing that market structure should explain the extent to which any given set of market offerings are substitutes or complements. We describe recent additions to the market structure analysis literature and identify promising directions for new research in market structure analysis. Impressive advances in data collection, statistical methodology and information technology provide unique opportunities for researchers to build market structure tools that can assist real-time marketing decision-making.

A note on some properties of the hypergeometric function with the last argument unity

Abstract

In this note some interrelationships between, and inequalities involving, the gamma and beta functions and the hyper geometric function with the last argument unity are established.     

The Potluck Problem

This paper proposes the Potluck Problem as a model for the behavior of independent producers and consumers under standard economic assumptions, as a problem of resource allocation in a multi-agent system in which there is no explicit communication among the agents.
