Business models and their relationship with marketing: A systematic literature review

The purpose of this paper is to identify the degree to which the marketing discipline has hitherto engaged with business model literature. The results of a systematic review of business model literature are presented and utilise both the citation counts and the h-index to objectively demonstrate the limited engagement that the marketing discipline has had with business model literature, and the limited degree that the discipline has influenced that literature. The key findings reveal a growing, but formative body of literature that, hitherto, has been dominated by non-marketing disciplines and which has only just begun to be addressed by present day marketing scholars. Using the most influential articles identified in the analysis, the paper concludes with a case for the empirical development of the business model concept with industrial marketing scholarship. Such development is argued to be grounded in the potential of open business models, co-created with multiple stakeholders in a supply chain and the end users of a value proposition.

Empirical analysis of the average asset correlation for real estate investment trusts

The credit risk capital requirements within the current Basel II Accord are based on the asymptotic single risk factor (ASRF) approach. The asset correlation parameter, defined as an obligor's sensitivity to the ASRF, is a key driver within this approach, and its average values for different types of obligors are to be set by regulators. Specifically, for commercial real estate (CRE) lending, the average asset correlations are to be determined using formulas for either income-producing real estate or high-volatility commercial real estate. In this paper, the value of this parameter was empirically examined using portfolios of U.S. publicly-traded real estate investment trusts (REITs) as a proxy for CRE lending more generally. CRE lending as a whole was found to have the same calibrated average asset correlation as corporate lending, providing support for the recent U.S. regulatory decision to treat these two lending categories similarly for regulatory capital purposes. However, the calibrated values for CRE categories, such as multi-family residential or office lending, varied in important ways. The comparison of calibrated and regulatory values of the average asset correlations for these categories suggests that the current regulatory formulas generate parameter values that may be too high in most cases.     

Analysis of the complexity of writing used in accounting textbooks over the past 100 years

The Accounting Education Change Commission (AECC) and the large international accounting firms have all emphasized that accountants must be able to work with unstructured problems to be successful in today's business environment. Measures of this ability are essential if accounting educators are to assist students in improving their abilities to work with unstructured problems. However, there appears to be no measure that has been widely accepted as being the ‘best’ measure. This study considers whether two linguistic performance measures might be usable by accounting educators for this purpose. We use data obtained from a student assessment centre to consider two measures of linguistic performance, idea density and grammatical complexity. We incorporate five criteria in deciding whether these measures could be usable: (1) whether the measures are related to students' performance when solving unstructured problems; (2) whether the measures distinguish between the ability to work with unstructured compared to structured problems; (3) ease of obtaining necessary information from students; (4) ease of scoring, and (5) robustness of the findings after considering other variables that may have an effect. Our results indicate that subjects' linguistic performance as measured by idea density meets these five criteria. However, grammatical complexity is not related to performance for either type of problem. These results were found even after controlling for the effects of other variables such as grade point average (GPA), experience, and personality variables. Because the measures can be obtained from virtually any written work produced by students, the information to be scored is relatively easy to obtain. Scoring is also relatively straightforward.

Bank business models and liquidity creation

Using a large panel of US bank holding companies from 2001 to 2015, this study investigates the association between functional diversification and bank liquidity creation. I document evidence of lower liquidity creation for higher diversification. The effect of moving into nontraditional activities on liquidity creation is more apparent with large banks and less pronounced with small banks. The impact of diversification on liquidity creation is less significant during the late stage of crisis and is more clearly observed in small and medium-sized banks. Low liquidity creation banks, leveraged by a higher share of non-interest income, are more likely to further decrease their liquidity creation. The study is of interest to regulators and policymakers who are concerned about bank business models.     

Investigation of factors affecting the diffusion of mobile telephone services: An empirical analysis for Vietnam

This paper analyzes the diffusion of mobile telecommunications services in Vietnam and examines how telecommunications regulation and potential substitute/complement services affect the growth of the number of mobile telephone subscribers. Using a logistic diffusion model, it is found that fixed telephone services are a complement while data services have a negative relation to mobile telephone services in Vietnam. As for regulation, the policy of introducing competition has been found to be the most effective in influencing the adoption of mobile services. Another important result is that the estimated potential market is roughly 76% of the total population. The findings suggest that suitable regulation that guarantees competition in the mobile telecommunications market in a developing country such as Vietnam is one of the most important factors for a positive diffusion process.     

ASSESSING THE IMPACT OF DISTRIBUTIVE POLICIES ON THE BRAZILIAN ECONOMY USING AN SCGE MODEL

This study investigates the impact of macroeconomic policies on the Brazilian economy. We present a two-sector, open-economy, Structuralist Computable General Equilibrium model that distinguishes among three economic classes and assumes no financial sector. The Social Accounting Matrix for Brazil in 2006 serves as a benchmark for our model. We compare the medium-run effects of five experiments: an income transfer towards formal workers, a transfer to informal labour, an investment shock, an exchange rate depreciation, and a policy mix that combines (exchange rate) depreciation with income transfer towards modern (sector) workers. The policy measures reinforce each other in terms of their potential to enhance growth. Our findings underscore the importance of redistributive policies to foster economic expansion.
