The Journal of Risk and Insurance: A 75-Year Historical Perspective

This research provides a comprehensive historical analysis of articles published in The Journal of Risk and Insurance over the 75‐year period from 1932 to 2006. Historical statistics are provided including the number of articles, number of authors per article, geographic location of contributors, leading contributors, author affiliation (industry or academic), the proportion of articles that are theoretical and empirical, and topics covered. Statistics relating to the entire 75‐year period are provided as well as breakdowns by decade. The results indicate that the contributors to The Journal of Risk and Insurance have become more international over time, average article length and average number of authors per article have increased over time, and empirical articles appear more frequently than theoretical articles.     

Empirically based modeling in financial economics and beyond, and spurious stylized facts

The discovery of the dynamics of a time series requires construction of the transition density. We explain why 1-point densities and scaling exponents cannot determine the class of stochastic dynamics. Time series require some sort of underlying statistical regularity to provide a basis for analysis, and we construct an exhaustive list of such tests. The condition for stationary increments, not scaling, determines the existence of long time pair autocorrelations. We conjecture that for a selfsimilar process neither the pair correlations 〈x(t)x(s)〉 nor the 2-point density scales in both times t and s except in a pathological case, and give examples using three well-known Gaussian processes. An incorrect assumption of stationary increments can generate spurious stylized facts, including fat tails. When a sliding window is applied to nonstationary, uncorrelated increments then a Hurst exponent H_s = 1 / 2 is generated by that procedure even if the underlying model scales with a Hurst exponent H ≠ 1/2. We explain how this occurs dynamically. The nonstationarity arises from systematic unevenness in the traders' behavior in real time. Spurious stylized facts arise mathematically from using a log increment with a ‘sliding window’ to read the series. In addition, we show that nonstationary processes are generally not globally transformable to stationary ones. We also present a more detailed explanation of our recent FX data analysis and modeling.     

A comparative analysis of proxies for an optimal leverage ratio

Previous studies that test the tradeoff theory commonly use one of the following debt ratio measures to proxy for a firm's hypothesized optimal ratio: firm's time-series mean leverage, moving average leverage based on a firm's historical debt ratios, industry median leverage, and predicted leverage ratio based on cross-sectional regressions. We find that these alternative proxies yield results that are significantly different from each other. Further, regression results of models that use the optimum target leverage and the conclusions drawn from the findings are sensitive to the model's proxy. Of the proxies that are commonly used in the literature, the moving average debt measure exhibits characteristics that are most consistent with the theoretical optimal leverage ratio.     

Comparing Malta and USA police officers’ individual and organizational support on outcomes

This paper investigates the quality of support for police officers in the USA and Malta to use as protection against stress. The authors found a significantly different organizational work context for police officers doing the same tasks. Police officers in both countries would benefit from upskilling in psychological capital and police managers require upskilling in management training as a means of increasing support for police to reduce the impact of stress.     

Corporate greed: its effect on customer satisfaction,corporate social responsibility and corporate reputation among bank customers

Corporate greed has received increasing attention in recent years with various stories hitting the headlines, particularly after the global financial crisis and the ensuing negative attitudes toward banks. Customer satisfaction and corporate social responsibility are known to have a positive effect on corporate reputation among customers, but perceived corporate greed is likely to impede their effect. Corporate greed, customer satisfaction, corporate social responsibility and corporate reputation are considered, and a research model is proposed. Results indicate that the effect of corporate greed is stronger on corporate social responsibility than on customer satisfaction, implying that corporate social responsibility activities may be futile if the company is perceived to be acting greedily by its customers. Thus, perceptions of corporate greed need to be dealt with swiftly, to enable management to enhance the corporate reputation of the firm.
