The impact of AACSB accreditation: A multiple case study of Canadian university business schools

Over the last two decades there has been a significant increase in the number of university business schools seeking accreditation from the Association to Advance Collegiate Schools of Business (AACSB International). Despite this remarkable growth there has been limited empirical research on this phenomenon. Using a qualitative multiple case study approach, this research explores the impact of accreditation on four Canadian university business schools. Participants reported seven main effects, with the most important being enhanced reputation, leverage for change, increased management efficiencies, and focus on research. These impacts were influenced by the context in which accreditation took place. Environmental uncertainty as a contextual dimension is discussed. Copyright © 2013 ASAC.

Strategic human resource management: a conceptual approach

In this paper conceptual issues associated with strategic human resource management are addressed. The rapidly expanding international interest in strategic human resource management is first highlighted. The article then explores some of the broader issues around the debate on SHRM that can inform thinking at a macro level. Firstly, the progress made towards understanding the meaning of SHRM is analysed, then a brief overview of the major models of SHRM to date is presented. This overview is used to highlight the key variables and interrelationships that need to be included in a model of SHRM, and a more detailed critical analysis of the contribution of the literature in each of these areas follows. A summary of the most important research questions arising out of the literature is followed by a model of the SHRM process, which attempts to remedy the major weaknesses in existing models of SHRM. The ways in which this model may be used as a basis for empirical research are then noted.

Is Privately‐provided Electronic Money Next?

To survive, any new electronic money will need to provide some advantage to its users, such as lower transaction costs, increased privacy, a greater ability to avoid taxes, or a more stable value than its government-provided competitors. Any successful new money will have to overcome substantial barriers to entry, however. These barriers to entry occur primarily in the form of the costs of switching to a different means of payment and require an understanding of the role played by 'network economics.' Unless a substantial number of the individuals and businesses with whom a person trades use the same money, any new means of payment will have little value. A temptation facing government regulators will be to extend and expand regulations to apply to new means of payment and forms of money. A more productive role of governments is to attempt to protect their own money-creation franchises by minimising the advantages offered by privately-provided alternatives. Governments should enforce contracts and punish fraud while remaining vigilant with respect to inflation, keep tax rates low and protect the privacy of their citizens.     

Risk, Wealth, and Sectoral Choice in Rural Credit Markets

We model the role of the informal credit sector in developing countries. The informational advantage of informal lenders is portrayed as the ability to monitor borrowers. Monitoring reduces the incentive problem and allows for contracts with lower collateral. This enables informal lenders to serve both individuals who cannot post the collateral required by the formal sector and those who are able but do not want to post collateral. The model is consistent with the conventional view of the informal sector as recipient of spillover demand from the formal sector. It also shows that the informal sector may provide partial insurance as the lower collateral requirement implies greater consumption smoothing for borrowers.     

Increasing correlations or just fat tails?

Increasing correlation during turbulent market conditions implies a reduction in portfolio diversification benefits. We investigate the robustness of recent empirical results that indicate a breakdown in the correlation structure by deriving theoretical truncated and exceedance correlations using alternative distributional assumptions. Analytical results show that the increase in conditional correlation could be a result of assuming conditional normality for the return distribution. When assuming a popular alternative distribution – the bivariate Student-t_r – we find significantly less support for an increase in conditional correlation and conclude that this is due to the presence of fat tails when assuming normality in the return distribution.     

Beware of ‘Good’ Outliers and Overoptimistic Conclusions*

The main goal of this paper is to warn practitioners of the danger of neglecting outliers in regression analysis, in particular, good leverage points (i.e. points lying close to the regression hyperplane but outlying in the x‐dimension). While the types of outliers which do influence regression estimates (vertical outliers and bad leverage points) have been extensively investigated, good leverage points have been largely ignored, probably because they do not affect the estimated regression parameters. However, their effect on inference is far from negligible. We propose a step‐by‐step procedure to identify and treat all types of outliers. The paper of Persson and Tabellini [American Economic Review (2004) Vol. 94, pp. 25–46] linking the degree of proportionality of an electoral system to the size of government is discussed to illustrate how the choice of a measure and the existence of atypical observations may substantially influence results.     

Real-world evidence of improved healthcare utilization in patients with schizophrenia or schizoaffective disorder after early treatment of paliperidone palmitate once-monthly treatment in Hong Kong

Background: Very few data are available to demonstrate the economic benefit of early paliperidone palmitate once-monthly long-acting injectable (PP1M) treatment in patients with schizophrenia or schizoaffective disorder.

Methods and materials: This study has retrospectively compared the healthcare utilization and associated costs of pre- and post-PPIM treatment in 413 patients with schizophrenia or schizoaffective disorder recruited from three major public hospitals providing psychiatric services in Hong Kong. Patients were categorized into early treatment (≤3 years since diagnosis) and chronic (>3 years) groups, and also whether they were receiving polypharmacy (POP).

Results: It was found that patients who were started on early therapy with no POP had the most favourable outcomes. Overall results of the entire cohort, including both early and late treatments, indicate that there was a slight increase in annual in-patient days (IP) per patient and outpatient visit (OP) by 3.18 and 1.87, respectively, and a decrease in emergency room visit (ER) of 0.9 (p?p?p?p?Conclusions: From the 413 patients studied, potential annual savings is higher by early administration of PPIM in patients with NP. Analysis using multivariate linear regression based on generalized estimating equations and sensitivity analysis using a linear mixed model supported the findings.     

Immigrants’ Wage Performance in a Routine Biased Technological Change Era: France 1994–2012

Over the period 1994–2012, immigrants’ wage growth in France outperformed that of natives. We investigate to what extent changes in task‐specific returns to skills contributed to this wage dynamics differential through two channels: changes in the valuation of skills (price effect) and occupational sorting (quantity effect). We find that the wage growth premium of immigrants is mainly explained by the progressive reallocation of immigrants toward tasks whose returns increase over time. Immigrants seem to have taken advantage of labor demand restructuring driven by globalization and technological changes.
