This paper deals with two problems in transport network planning and control: trip matrix estimation and traffic signal optimisation. These two problems have both been formulated as bi-level programming problems with the User Equilibrium assignment as the second-level programming problem. One currently used method for solving the two problems consists of alternate optimisation of the two sub-problems until mutually consistent solutions are found. However, this alternate procedure does not converge to the solution of the bi-level programming problem. In this paper, a new algorithm will be developed and will be applied to two road networks.

The paper considers a discrete-time, Markov, stochastic process model of drivers' day-to-day evolving route choice, the evolving ‘state’ of such a system being governed by the traffic interactions between vehicles, and the adaptive behaviour of drivers in response to previous travel experiences. An approximating deterministic process is proposed, by approximating both the probability distribution of previous experiences—the “memory filter”—and the conditional distribution of future choices. This approximating process includes both flow means and variances as state variables. Existence and uniqueness of fixed points of this process are examined, and an example used to contrast these with conventional stochastic equilibrium models. The elaboration of this approach to networks of an arbitrary size is discussed.

The purpose of this paper is to identify five quality improvement initiatives for healthcare system leaders, produced by such leaders themselves, and to provide some guidance on how these could be implemented.

A multi-stage modified-Delphi process was used, blending the Delphi approach of iterative information collection, analysis and feedback, with the option for participants to revise their judgments.

The process reached consensus on five initiatives: change information privacy laws; overhaul professional training and work in the workplace; use co-design methods; contract for value and outcomes across health and social care; and use data from across the public and private sectors to improve equity for vulnerable populations and the sickest people.

Information could not be gathered from all participants at each stage of the modified-Delphi process, and the participants did not include patients and families, potentially limiting the scope and nature of input.

The practical implications are a set of findings based on what leaders would bring to a decision-making table in an ideal world if given broad scope and capacity to make policy and organisational changes to improve healthcare systems.

This study adds to the literature a suite of recommendations for healthcare quality improvement, produced by a group of experienced healthcare system leaders from a range of contexts.

Attempts to theorize the relationship between the informal and the illegal sectors of the economy. States that there are significant behavioural similarities. Proposes an emergent paradigm based on dual labour market theory to explain the similarites and differences in order to guide future research in each area. Applies the theory to the production and marketing of crack cocaine and shows how the model helps us to understand issues of exploitation and risk makagement within the drug market.

Evidence suggests habitual entrepreneurs (i.e. those with prior business ownership experience) are a widespread phenomenon. Appreciation of the existence of multiple entrepreneurial acts gives rise to the need to examine differences between habitual and novice entrepreneurs (i.e. those with no prior business experience as a founder, inheritor or purchaser of a business). This paper synthesizes human capital and cognitive perspectives to highlight behavioral differences between habitual and novice entrepreneurs. Issues relating to opportunity identification and information search, opportunity exploitation and learning are discussed. Avenues for future research are highlighted.

The purpose of this paper is to explore the value of oral history for marketing historians and provide case studies from projects in the Australian context to demonstrate its utility. These case studies are framed within a theme of market research and its historical development in two industries: advertising and retail property.

This study examines oral histories from two marketing history projects. The first, a study of the advertising industry, examines the globalisation of the advertising agency in Australia over the period spanning the 1950s to the 1980s, through 120 interviews. The second, a history of the retail property industry in Australia, included 25 interviews with executives from Australia’s largest retail property firms whose careers spanned from the mid-1960s through to the present day.

The research demonstrates that oral histories provide a valuable entry port through which histories of marketing, shifts in approaches to market research and changing attitudes within industries can be examined. Interviews provided insights into firm culture and practices; demonstrated the variability of individual approaches within firms and across industries; created a record of the ways that market research has been conducted over time; and revealed the ways that some experienced operators continued to rely on traditional practices despite technological advances in research methods.

Despite their ubiquity, both the advertising and retail property industries in Australia have received limited scholarly attention. Recent scholarship is redressing this gap, but more needs to be understood about the inner workings of firms in an historical context. Oral histories provide an avenue for developing such understandings. The paper also contributes to broader debates about the role of oral history in business and marketing history.

This study aims to investigate the effect of public corruption on the performance and risk of financial institutions domiciled in the USA..

This study uses the US Department of Justice’s (DOJ) Public Integrity Section Reports to proxy corruption. The analysis is performed by bank size and includes robustness checks for omitted variables and endogeneity concerns.

The results show that a corrupt environment is associated with lower bank performance without a reduction in risk. Larger banks tend to underestimate the increase in credit risk. Small- and medium-size banks seek to “re-capture” returns in corrupt districts by reducing their liquidity.

The implication of this research is that financial institutions do not thrive in corrupt environments and are unlikely to participate in corrupt practices. Overall, this study documents the tangible harm inflicted by corrupt practices.

A practical implication is that banks may attempt to re-capture lower returns resulting from corrupt environments by extending more risky loans, specifically, commercial real estate loans.

This study demonstrates the costly impact of corruption on large and small banks. While larger banks report higher share of non-performing loans, smaller banks show an increase in the provision for loan and lease losses, suggesting that smaller banks may be more risk averse.

Prior studies investigate corruption in US firms while excluding financial institutions. This study fills this gap by investigating the effect of public corruption on the performance and risk of financial institutions domiciled in the USA.

Corruption was ranked among the top five biggest obstacles affecting the operation of enterprises in Africa and was rated as a severe obstacle by close to 40 percent of firms in the sample. Consequently, the purpose of this paper is to investigate the relationship between corruption and firm level productivity.

This paper uses the Enterprise Survey Data Set of the World Bank and employs an instrumental variable (IV) approach to deal with the potential endogeneity of corruption in a productivity equation. The authors use industry-country averages of the bribe tax and time tax as well as a dummy of female ownership as IVs.

Using three different measures of corruption, the authors find evidence that corruption “sands the wheels of commerce” and hence dampens firm-level productivity even when the endogeneity of corruption is controlled for. The authors find no evidence to support the trade-off between bribe payments and the red tape suggesting that government officials deliberately use bureaucracy as a mechanism of trapping the most productive firms that can afford to pay higher bribes. Hence this study lends no support to the “greasing” hypothesis.

The results thus suggest that in the second best choice environment firms are still not better off paying bribes rather mitigating corruption could be ideal. Therefore alongside existing regulatory corruption mitigants in the respective African countries, the paper suggests that government through public information dissemination ought to enlighten firms that corruption is not productivity enhancing. Thus firms are better-off evading corruption tendencies than propagating them.

The contribution to empirical literature is that much of the empirical studies have overly concentrated on Europe and Asia and with very limited evidence available for African countries. Therefore in terms of extending the work of McAuthar and Teal (2002) and Fisman and Svensson (2007), the authors argue that by using a new data set stretching from 2006 to as recent as 2017 the paper is rightly placed to make an empirical contribution about the relationship between corruption and firm-level productivity.

President Bill Clinton has had many opponents and enemies, most of whom come from the political right wing. Clinton supporters contend that these opponents, throughout the Clinton presidency, systematically have sought to undermine this president with the goal of bringing down his presidency and running him out of office; and that they have sought non‐electoral means to remove him from office, including Travelgate, the death of Deputy White House Counsel Vincent Foster, the Filegate controversy, and the Monica Lewinsky matter. This bibliography identifies these and other means by presenting citations about these individuals and organizations that have opposed Clinton. The bibliography is divided into five sections: General; “The conspiracy stream of conspiracy commerce”, a White House‐produced “report” presenting its view of a right‐wing conspiracy against the Clinton presidency; Funding; Conservative organizations; and Publishing/media. Many of the annotations note the links among these key players.
