Why do Banks Fail?

Banks advance loans in the absence of precise knowledge in relation to the outcome of borrowers' projects. Consequently, uncertainty in relation to loan repayment emerges. Thus, banks introduce the 'credit standard' as insurance against loans, so that should borrowers' projects fail, borrowers have an alternative means of honouring their debt obligations. It is argued in this paper that in the competitive atmosphere under which this sector operates, it is not possible to secure the entire loan portfolio by introducing the credit standard, and in recent years this difficulty has been further exacerbated by financial liberalisation, which may have caused bank failures.     

Customer loyalty: Toward an integrated conceptual framework

Customer loyalty is viewed as the strength of the relationship between an individual’s relative attitude and repeat patronage. The relationship is seen as mediated by social norms and situational factors. Cognitive, affective, and conative antecedents of relative attitude are identified as contributing to loyalty, along with motivational, perceptual, and behavioral consequences. Implications for research and for the management of loyalty are derived. His research interests include consumer decision making, information processing, and consumer loyalty. He has published in theJournal of Consumer Research andAdvances in Consumer Research. His research interests are consumer information processing, persuasion cues in advertising, and international marketing. His articles have appeared in theJournal of Consumer Research, Journal of Marketing Research, Journal of Consumer Psychology, andCanadian Journal of Administrative Sciences as well as in a number of conference proceedings.     

What drives the cross‐country growth and inequality correlation?

Abstract.  We present a neo‐classical model that explores the determinants of growth‐inequality correlation and attempts to reconcile the seemingly conflicting evidence on the nature of the growth‐inequality relationship. The initial distribution of human capital determines the long‐run income distribution and the growth rate by influencing the occupational choice of the agents. The steady‐state proportion of adults that innovates and updates human capital is path dependent. The output elasticity of skilled‐labour, barriers to knowledge spillovers, and the degree of redistribution determine the range of steady‐state equilibria. From a calibration experiment we report that a skill‐intensive technology, low barriers to knowledge spillovers, and high degrees of redistribution characterize the industrial countries with a positive growth‐inequality correlation. A negative correlation between growth and inequality arises for the group of non‐industrial countries with the opposite characteristics. JEL classification: E1, O4     

Redistributive Tax and Growth in a Model with Discrete Occupational Choice

An optimal redistributive tax-subsidy formula is derived for a growth model where income inequality is endogenously driven by an adult's choice of occupation between work and management. Investment in human capital is the engine of growth. The world's stock of exploitable knowledge as well as the economy's average human capital determine the potential rate of return from investment in human capital in an economy. How much available knowledge would be exploited in the economy depends on the proportion of innovators in our model. A redistributive tax reform impacts growth as well as income inequality via its influence over the occupational choice. The optimal redistributive tax rate is path-dependent in the sense that it depends on the initial wealth distribution. The normative implication of the model is that the optimal capital income tax rate could very well be positive if the initial wealth inequality exceeds a threshold. The optimal capital income tax rate depends inversely on the initial wealth inequality.     

Another Look at Wage Distortion in a Developing Dual Economy

The paper focuses on an endogenous wage distortion in a developing dual economy where an efficiency wage in the urban sector triggers rural-urban migration. Because of the endogenous nature of the distortion, this migration reduces the severity of distortion by creating more jobs and reducing the actual wage differential between the sectors. These results are in sharp contrast to the outcomes of an exogenous wage distortion (minimum wage) where rural-urban migration increases the severity of unemployment and calls for costly policy mechanisms that might be either politically or economically difficult to implement. Furthermore, in contrast to the case of an exogenous distortion, interregional migration with endogenous wage distortion increases urban industrial output and structural transformation works its way into the development process. This structural transformation is maintained even when this dual economy engages in the production of non-traded goods. Although this paper does not engage in policy ranking to bring in zero unemployment equilibrium, it shows that it is possible to achieve socially desirable level of migration by influencing detection rate of shirking or disutility of work effort instead of using costly distributive parameters such as taxes and subsidies.     

Trends and Future Directions in Online Marketing Research

Over the last decade, the increased adoption of the Internet in public life as well as in developing businesses has led to a phenomenal rise in academic research on online marketing. This article is set to extensively review scholarly articles appearing from 2000 to 2014 on the topic from 10 top-tier academic journals to understand the research trends in the domain. A literature review has reported eight major subjective categories with an analysis of online marketing effectiveness framework. This review found three most significant subject categories: (1) online marketing issues; (2) Internet usage, perception, and attitude; and (3) online shopping and e-commerce. Additionally, some new online marketing research topics such as word-of-mouth, user-generated content, and social network are also highlighted. Finally, a selection of research topics that got the maximum attention of researchers is presented along with discussion of the future research directions in the online marketing space.     

Bias of OLS Estimators due to Exclusion of Relevant Variables and Inclusion of Irrelevant Variables

In this paper, I discuss three issues related to bias of OLS estimators in a general multivariate setting. First, I discuss the bias that arises from omitting relevant variables. I offer a geometric interpretation of such bias and derive sufficient conditions in terms of sign restrictions that allows us to determine the direction of bias. Second, I show that inclusion of some omitted variables will not necessarily reduce the magnitude of bias as long as some others remain omitted. Third, I show that inclusion of irrelevant variables in a model with omitted variables can also have an impact on the bias of OLS estimators. I use a running example of a simple wage regression to illustrate my arguments.     

The appropriateness of default investment options in defined contribution plans: Australian evidence

For participants in defined contribution (DC) plans who refrain from exercising investment choice, plan contributions are invested following the default investment option of their respective plans. Since default investment options of different plans vary widely in terms of their benchmark asset allocation, the most important determinant of investment performance, participants enrolled in these options face significantly different wealth outcomes at retirement. This paper simulates the terminal wealth outcomes under different static asset allocation strategies to evaluate their relative appeal as default investment choice in DC plans. We find that strategies with low or moderate allocation to stocks are consistently outperformed in terms of upside potential of exceeding the participant's wealth accumulation target at retirement as well as downside risk of falling below that target outcome by aggressive strategies whose allocation to stocks approach 100%. The risk of extremely adverse wealth outcomes for plan participants also does not appear to be very sensitive to asset allocation. Our evidence suggests the appropriateness of strategies heavily tilted towards stocks to be nominated as default investment options in DC plans unless plan providers emphasize predictability of wealth outcomes over adequacy of retirement wealth.
