Linguistic sleuthing for innovators

Quality & Quantity - For centuries “innovation” has been a topic of book authors and academic researchers as documented by Ngram and Google Scholar search results. In contrast,...     

Why leaders don't learn from success

What causes so many companies that once dominated their industries to slide into decline? In this article, two Harvard Business School professors argue that such firms lose their touch because success breeds failure by impeding learning at both the individual and organizational levels. When we succeed, we assume that we know what we are doing, but it could be that we just got lucky. We make what psychologists call fundamental attribution errors, giving too much credit to our talents and strategy and too tittle to environmental factors and random events. We develop an overconfidence bias, becoming so self-assured that we think we don't need to change anything. We also experience the failure-to-ask-why syndrome and neglect to investigate the causes of good performance. To overcome these three learning impediments, executives should examine successes with the same scrutiny they apply to failures. Companies should implement systematic after-action reviews to understand all the factors that led to a win, and test their theories by conducting experiments even if "it ain't broke."     

Service Science Management Engineering and Design (SSMED): a semiautomatic literature review

ABSTRACT

SSMED (Service Science, Management Engineering and Design) is multidisciplinary by nature. However, some authors stated that SSMED publications remain focused on single scientific domains. This paper proposes a Semiautomatic Literature Review (SALR) using integrated techniques for knowledge extraction –‘Time Aware Knowledge Extraction’ (TAKE) – to analyse the interdisciplinarity of SSMED publications and the potential for transdisciplinarity based on the actual adoption of Service-Dominant Logic as the foundation of SSMED research. Findings reveal that: 1) most SSMED publications are not interdisciplinary and are mainly related to Management; 2) Service-Dominant Logic has been adopted very often in SSMED publications, paving the way for SSMED transdisciplinarity.

This paper offers theoretical and practical insights by enhancing the knowledge about SSMED literature and enriching the state of the art related to techniques to perform literature reviews. Furthermore, it stimulates the expansion of scholars’ and managers’ views of holistic approaches to service systems while fostering SSMED viability.     

Principal components at work: the empirical analysis of monetary policy with large data sets

The empirical analysis of monetary policy requires the construction of instruments for future expected inflation. Dynamic factor models have been applied rather successfully to inflation forecasting. In fact, two competing methods have recently been developed to estimate large‐scale dynamic factor models based, respectively, on static and dynamic principal components. This paper combines the econometric literature on dynamic principal components and the empirical analysis of monetary policy. We assess the two competing methods for extracting factors on the basis of their success in instrumenting future expected inflation in the empirical analysis of monetary policy. We use two large data sets of macroeconomic variables for the USA and for the Euro area. Our results show that estimated factors do provide a useful parsimonious summary of the information used in designing monetary policy. Copyright © 2005 John Wiley & Sons, Ltd.     

Reimbursing Preventive Care

The paper focuses on secondary prevention, such as diagnostic screening, medical examinations and checks-up, which refers to the early detection of disease. Secondary prevention is analyzed as a self-insurance activity reducing the negative shock of illness and can be either complement or substitute to illness treatment. This paper analyses the optimal reimbursement scheme for both prevention and treatment when each activity receives either a linear subsidy (i.e. cost sharing) or tax. Although optimal reimbursement systematically encourages treatment, it positively affects prevention if and only if prevention reduces the cost of treatment, that is in the case the two activities are substitutes.     

Removing Homeownership Bias in Taxation: The Distributional Effects of Including Net Imputed Rent in Taxable Income

The income tax systems of most countries entail a favourable treatment of homeownership, compared to rental‐occupied housing. Such ‘homeownership bias’ and its consequences for a wide range of economic outcomes have long been recognised in the economic literature. Although a removal of the homeownership bias is generally advocated on efficiency grounds, its distributional implications are often neglected, especially in a cross‐country perspective. In this paper, we aim to fill this gap by investigating the first‐order effects, in terms of distribution of income and work incentives, of removing the income tax provisions favouring homeownership. We consider six European countries – Belgium, Germany, Greece, Italy, the Netherlands and the UK – that exhibit important variation in terms of income tax treatment of homeowners. Using the multi‐country tax benefit model EUROMOD, we analyse the distributional consequences of including net imputed rent in the taxable income definition that applies in each country, together with the removal of existing special tax treatments of incomes or expenses related to the main residence; thus, we provide a measure of the homeownership bias. We implement three tax policy scenarios. In the first, imputed rent is included in the taxable income of homeowners, while at the same time existing mortgage interest tax relief schemes and taxation of cadastral incomes are abolished. In the two further revenue‐neutral scenarios, the additional tax revenue raised through the taxation of imputed rent is redistributed to taxpayers, through either a tax rate reduction or a tax exemption increase. The results show how including net imputed rent in the tax base might affect inequality in each of the countries considered. Housing taxation appears to be a promising avenue for raising additional revenues, or lightening taxation of labour, with no inequality‐increasing side effects.     

Consolidation in the public sector: a cross-country comparison

This article analyses consolidated annual accounts in the public sector in six countries (Sweden, the UK, the USA, Canada, New Zealand and Australia) highlighting the differences and similarities in approaches. The authors also examine international trends and take an in-depth look at the International Public Sector Accounting Standards Board (IPSASB).     

Scrutinizing local public service provision

Set in the context of an expansion of scrutiny by local authorities of local service provision, this article explores the key challenges ahead for managers and politicians in this area of local governance. Drawing on an evaluation of the development of health scrutiny, it outlines the different types of activities health scrutiny committees are engaging in to fulfil their legislative commitments and suggests lessons for the expansion of external scrutiny.
