Does bank competition promote financial inclusion? A cross-country evidence

The idea of financial inclusion has recently been discussed as one of the key strategies to enhance economic development (World Bank 2014). We move this discussion forward by examining if bank competition is a crucial component enforcing financial inclusion, which is arguably a finance supply-side driven process. In this study, we compute the financial inclusion index built on Sarma (2008) approach to better reflect banks’ willingness and capability to provide financial services. Applying System Generalized Method of Moments to the panel of 93 countries, we find that bank competition promotes financial inclusion.     

Involuntary excess reserve and bankers’ remuneration: evidence from Chinese banks

This article analyses the effects of involuntary excess reserves (IER) on bankers’ remuneration and the penalty associated with bank risk-taking if discovered. The study finds that IER help conceal tail risks, improves bankers’ performance and remuneration. However, the risks once discovered result in heavy penalties on bankers’ remuneration. The study extends the agency theory to the context where banks hold large IER.     

The need for a strategic approach on the railways to the management of the vehicle–track interface

Network Rail's decision in 2003 to bring track maintenance back in-house was long-overdue recognition that responsibility for safety on Britain's railways cannot be abdicated – but there was more to it than that. The accidents at Hatfield and Potter's Bar (both in Hertfordshire, UK), in particular, had exposed very vividly how privatisation had encouraged each now separated and competing part of the industry to operate in its own interests: records, data and expertise were fragmented, and track and train operators alike each sought to minimise their individual costs in isolation. This paper argues from a systems analysis perspective that, on vehicle and track maintenance at least, the overall costs to the industry are in such circumstances likely to be higher than if the various parties were to work together towards minimising total track and train maintenance costs between them. Far from increasing efficiency, privatisation had the effect of reducing it.     

Information and Communication Technology (ICT) and Singapore’s economic growth

Singapore’s remarkable success in economic development has been strongly associated with the country’s vigorous efforts to embrace the Information and Communication Technology (ICT) revolution to promote economic growth. This study provides a comprehensive investigation of the contributions of ICT to Singapore’s economic growth during the 1990–2008 period. It documents three key findings. First, there is a strong positive association between the intensity of ICT use and value-added and labor productivity growth at the sector level. Second, ICT investment contributed approximately 1 percentage point to Singapore’s GDP during 1990–2008, and its role in driving economic growth has become increasingly important over time. Third, the contribution of the ICT manufacturing sector to Singapore’s growth was notable, but it was on the decline and faced difficult restructuring challenges. This paper also provides valuable policy lessons and strategic insights for governments in both developed and developing countries that aspire to embrace ICT to promote economic growth.     

Prescribed conditional interaction structure models with application to the analysis of mobility tables

The present paper considers some new models for the analysis of multidimensional contigency tables. Although the theoretical background used here appeared already in Haberman (1974), prescribed conditional interaction (PCIN) models were introduced by Rudas (1987) and their mathematical properties were worked out by Leimer and Rudas (1988). These models are defined by prescribing the values of certain conditional interactions in the contingency table. Conditional interaction is defined here as the logarithm of an appropriately defined conditional odds ratio. This conditional odds ratio is a conditional version of a generalization of the well known odds ratio of a 2×2 table and that of the three factor interaction term of a 2×2×2 table and applies to any number of dimensions and any number of categories of the variables. The well known log-linear (LL) models are special PCIN models. Estimated frequencies under PCIN models and tests of fit can be computed using existing statistical software (e.g. BMDP). The paper describes the class of PCIN models and compares it to the class of association models of Goodman (1981). As LL models are widely used in the analysis of social mobility tables, application of more general PCIN models is illustrated.
