Wage bargaining,productivity growth and long-run industry structure

This paper studies the innovation dynamics of an oligopolistic industry. The firms compete not only in the output market but also by engaging in productivity enhancing innovations to reduce labor costs. Rent sharing may generate productivity dependent wage differentials. Productivity growth creates intertemporal spillover effects, which affect the incentives for innovation at subsequent dates. Over time the industry equilibrium approaches a steady state. The paper characterizes the evolution of the industry's innovation behavior and its market structure on the adjustment path.     

The case for gender mainstreaming Botswana's privatisation process

Botswana embarked on privatisation in 2000 but the programme is yet to be implemented. The objectives of privatisation are to promote citizen economic empowerment and to benefit all. Admittedly, these are well-intended objectives. However, we pose a question: ‘How are these objectives going to be achieved?’ To answer this question, this paper audits the Privatisation Policy of Botswana and Privatisation Master Plan to assess the extent to which they are gender inclusive, and concludes that they are gender blind and do not address the gender dimensions of privatisation. The paper also reviews secondary data such as poverty maps and concludes that women suffer socio-economic disenfranchisement and would not equally benefit from privatisation. In addition, women would disproportionately suffer its adverse effects. For privatisation to produce fair outcomes, there is a need to make it gender inclusive. Making it gender inclusive would ensure the participation and empowerment of socio-economic minorities such as women.     

Robust adaptive rate-optimal testing for the white noise hypothesis

A new test is proposed for the weak white noise null hypothesis. The test is based on a new automatic selection of the order for a Box–Pierce (1970) test statistic or the test statistic of Hong (1996). The heteroskedasticity and autocorrelation-consistent (HAC) critical values from Lee (2007) are used, allowing for estimation of the error term. The data-driven order selection is tailored to detect a new class of alternatives with autocorrelation coefficients which can be o(n^−1/2)$o\left(n^{-1/2}\right)$ provided there are sufficiently many of such coefficients. A simulation experiment illustrates the good statistical properties of the test both under the weak white noise null and the alternative.

Service sabotage: The dark side of service dynamics

While many aspects of services research assume that employees are largely compliant to management prescribed service standards, a number of recent studies have highlighted the deliberate sabotage by service workers as a key issue. We contend that service sabotage is important not simply because of the pervasiveness of such behaviors, but also because of the impact that such acts can have on firm growth and profitability. Consequently, we seek to achieve three inter-linked objectives in this article. First, we highlight how service saboteurs harm customers’ service experiences and negatively affect the performance of the firm. Second, in order to assist managers in recognizing these behaviors, we identify the most common types of service saboteurs and forms of sabotage. Specifically, we classify and describe four main types of service saboteurs: Thrill Seekers, Apathetics, Customer Revengers, and Money Grabbers. Finally, and most importantly, we provide a series of suggestions regarding how managers might effectively address service sabotage in their firms. These include gathering information and exploiting existing data to establish the extent and nature of sabotage, recruiting the right quality of service staff, training and rewarding employees, enriching and empowering employees, developing a service culture, and initiating better monitoring systems and procedures.     

Using Elasticities to Derive Optimal Income Tax Rates

This paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates. A simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution. In the general non-linear income tax problem, this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of Mirrlees. The optimal non-linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution. These formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters.     

Distribution of Marketing Research Material to Universities: The Case of Archive of Market and Social Research (AMSR)

ABSTRACT

The aim of this note is to understand how content relating to marketing and market research is distributed to and within universities. The focus of the study includes the behavior of all those in this market for information, namely suppliers (whether content generators, aggregators, packagers, or distributors of content) of marketing research, university staff, and students. The case study method was implemented to collect data. The case study focuses on UK Higher Education. Specifically, the authors use the case study of the newly developed Archive of Market and Social Research (AMSR) to explore how content relating to marketing and market research is distributed to and within universities. The research involved personal interviews with 15 librarian senior managers selected from 14 universities.

The interviews with librarians provided insight into how AMSR could be distributed to university libraries and how it could be accessed. The findings highlight the role of university academics in specifying the content of marketing and market research. They focus on ‘real world’ management problems to deliver research with impact and relevant teaching. Therefore, they need company and industry information and are more likely to use current sources. The study maps the process of acquisition of marketing and market research content by universities and identifies the different roles involved in this process. The study is in line with the emerging literature that focuses on the role of education in explaining the relevance gap in marketing research. The study contrasts between the situation in the university market and industrial buying and adds to our understanding of the complexities associated with the distribution of the marketing research material. The result is expected to be a much sharper focus for the marketing of the archive material, leading to greater use of recent high-quality market research by marketing educators, and changes to marketing and market research syllabuses.

This note provides insight into how suppliers (whether content generators, aggregators, packagers, or distributors of content) of market and marketing research should market to universities and ensure the use of their information resources by students and teachers and how they should. The findings of the study contribute to understanding customer needs and shaping a new service product proposition. In addition, the study provides insight into how university students and staff access and should access commercial research on marketing from the market research industry (in particular from the Archive of Market and Social Research) and use it in their learning, so that their knowledge will be more up to date and their employability will be increased. Adding several insights to the issue of distribution of marketing research material to universities. The paper relates to the marketing of information resources to universities, specifically to the work of the Archive of Market and Social Research, in marketing their information assets to universities, and more specifically the relationship between the “push” of suppliers, libraries, journal and textbook suppliers and information aggregators (such as EBSCO and JISC) and the pull coming from academic researchers and lecturers, who might use this information in their teaching and research. The present study can be seen as a classic case study of understanding buyer behavior, but in a modern world of information platforms, aggregation, and the digital economy.     

Risk arbitrage and hedging to acceptability under transaction costs

The classical discrete-time model of proportional transaction costs relies on the assumption that a feasible portfolio process has solvent increments at each step. We extend this setting in two directions, allowing convex transaction costs and assuming that increments of the portfolio process belong to the sum of a solvency set and a family of multivariate acceptable positions, e.g. with respect to a dynamic risk measure. We describe the sets of superhedging prices, formulate several no (risk) arbitrage conditions and explore connections between them. In the special case when multivariate positions are converted into a single fixed asset, our framework turns into the no-good-deals setting. However, in general, the possibilities of assessing the risk with respect to any asset or a basket of assets lead to a decrease of superhedging prices and the no-arbitrage conditions become stronger. The mathematical techniques rely on results for unbounded and possibly non-closed random sets in Euclidean space.

     

Compound trend renewal process with discounted claims: a unified approach

We derive recursive formulas for the moments of compound trend renewal sums with discounted claims. An integral expression for the moment generating function of this risk process is then obtained, from which particular distribution functions are found. We extend the compound (deterministic) trend renewal process by assuming a stochastic trend, a stochastic force of net interest and a stochastic dependence between the inter-occurrence times and the severities of the claims. Finally, stochastic dominance ordering is also observed between the compound trend renewal process and an associated non-homogeneous Poisson process.     

Adjusting an institutional framework to a globalising world: the creation of new institutions in the EEC, 1957-1992

ABSTRACT

This article explores the development of all new EEC institutions between 1957 and 1992 within policy areas relevant to the possible development of a European single currency. It argues that if most institutions created pre-1992 were not crisis management institutions as would be the case post-2008, some important institutions were created in response to the perception of a structural international banking/political/economic crisis, particularly in the 1970s. This comparison in time underlines the continuity of reflections about the missing elements of a functioning single currency area, the obstacles to reform, and sheds light on the radical institutional changes that occurred post-2008.
