Winecon: An Evaluation

This paper presents the results of an evaluation of the WinEcon computer-based learning (CBL) software released into the academic community in September 1995. The focus of the paper is the impact of continued and directed WinEcon use on students' learning as measured by their examination results. The subjects of the study were the 240 Leicester University students enrolled on the 1995/96 introductory microeconomics course who were categorised by their use of WinEcon. Using traditional regression and decomposition techniques, we show that directed use of WinEcon can enhance exam performance by a small but significant proportion, enough to improve the pass rate of the overall course.

Crime and Racial Composition in Contiguous Communities as Negative Externalities: Prejudiced Household's Evaluation of Crime Rate and Segregation Nearby Reduces Housing Values and Tax Revenues

Abstract . How the level of amenities in surrounding communities affects the residential location decisions of households is considered. The amenities specifically taken into account are the crime and racial composition of the household's community and the contiguous communities. The theory of the household's valuation of neighborhood amenities through a housing value equation is expanded to include how the household's valuation of amenities is affected by the amenities in surrounding areas. An empirical model using data for 71 suburban communities in the Chicago Standard Metropolitan Statistical Area is specified to measure the simultaneous interaction between housing values, crime, and police effort. A revenue equation is included to determine how the household's valuation of crime and racial composition could affect the community's revenue-raising ability. The empirical results indicate that the crime and racial composition of surrounding communities as well as within the household's community have a statistically significant negative effect on housing values. While the magnitude of the effect is small, the empirical results suggest that households consider the crime rate and racial composition of surrounding communities as negative externalities.

Australia's Carbon Tax: An Economic Evaluation

Australia's carbon tax has been in place since July 2012. Following the 2013 federal election and change of government, it is likely that the tax will be abolished. This paper evaluates Australia's carbon tax experience and draws lessons for policymakers in other jurisdictions who may be considering following the Australian example and implementing their own carbon taxes or cap and trade schemes. Overall, the policy was poorly thought through, badly implemented, and lacked majority public support before it began. Australia's carbon tax experience is an interesting case study in how not to go about implementing climate change policy.     

Synergy Evaluation in Mergers and Acquisitions: An Attention-Based View

A core objective of corporate development relates to scope decisions, which regularly involve mergers and acquisitions (M&A). The dominant idea behind M&A is often captured by the umbrella term ‘synergy’. Yet, while performance is the key variable of most M&A studies, how firms arrive at a particular synergetic value for a target firm is not well understood. In this article, we contribute to this body of research. We argue that understanding the determination of synergies in M&A requires a look at the mechanisms that guide managerial attention towards specific valuation practices and synergy types. Specifically, by drawing on the attention-based view of the firm, we show that the evaluation of synergies cannot be divorced from the underlying attention structure in the M&A context and the various valuation practices that constitute different synergy types. Our analysis suggests that synergies often do not reflect the true potential of acquisitions. We reveal that this is due to an attentional crowding-out effect: The congruence of M&A attention structures with valuation practices for functional synergies crowd out the attention allocation to business models and strategic synergies. We describe the characteristics of this crowding-out effect as well as its implications.     

Trust in Business to Business Relationships: An Evaluation of its Status

The concept of trust has been used in a growing number of empirical and theoretical marketing studies of business to business relationships. Examination of a number of influential studies indicates a lack of clarity in their conceptualization of trust. The nature of this lack of clarity is examined and it is proposed that there are a number of features of trust which account should be taken of when conducting such studies.     

Crime in urban areas: New evidence and results

Crime supply functions are reestimated in this paper using data corrected for victim underreporting. It is found in both a mean-variance specification and a conventional crime supply function, which includes measures of the offender's gains and losses involved in property crimes, that certainty and severity of punishment still deter. When correction for underreporting is made, the effects on the rates of robbery, burglary, larceny, and auto theft of increases in prison admission rates and prison sentence lengths remain negative. This seeming support for the “deterrence hypothesis” must be balanced against the strong evidence that improved legitimate opportunities have a negative effect on crime. Use of improved crime data and a more intuitive economic specification of the offense supply function leads to the conclusion that higher income is a better deterrent to some crimes than increased punishment.

Evaluation of efficiency in Colombian hospitals: An analysis for the post-reform period

In this study we analyze the performance of 602 level 1 Colombian hospitals for the period 2009–2013. The analysis is carried out from both static and temporal perspectives in order to evaluate the evolution of total factor productivity (change in hospital performance) and its components throughout the period. The study also explores a question relevant not only to the Colombian health system, but to many others around the world, of whether primary care centers excessively refer patients to high-level hospitals, thereby negatively affecting the quality, efficiency, and effectiveness of all healthcare service provision. The results demonstrated that adjusted production (service provision) and levels of quality and referrals to higher-level hospitals could be improved, on average, by 44%. This increase in health service provision levels and their quality can be achieved by reducing personnel expenditure (by an average of 22%), expenditure on medicines (by 20%), and purchasing expenses (by 11%). The temporal analysis shows that total factor productivity (hospital performance change) worsened by 1% during the period, mainly due to the technological backlash experienced despite a slightly positive evolution in efficiency.     

Advances in the Analysis of Non-stationary Time Series: An Illustration of Cointegration and Error Correction Methods in Research on Crime and Immigration

Time series data of interest to social scientists often have the property of random walks in which the statistical properties of the series including means and variances vary over time. Such non-stationary series are by definition unpredictable. Failure to meet the assumption of stationarity in the process of analyzing time series variables may result in spurious and unreliable statistical inferences. This paper outlines the problems of using non-stationary data in regression analysis and identifies innovative solutions developed recently in econometrics. Cointegration and error-correction models have recently received positive attention as remedies to the problems of ``spurious regression' arising from non-stationary series. In this paper, we illustrate the relevant statistical concepts concerning these methods by referring to similar concepts used in cross-sectional analysis. An historical example is used to demonstrate how such techniques are applied. It illustrates that ``foreign' immigrants to Canada (1896–1940) experienced elevated levels of social control in areas of high police discretion. ``Foreign' immigration was unrelated to trends in serious crimes but closely related to vagrancy and drunkenness. The merits of cointegration are compared to traditional approaches to the regression analysis of time series.     

Ayres' Theory of Economic Progress: An Evaluation of Its Place in Economic Literature

A bstract . Clarence E. Ayres was unfortunate in certain of his critics; they missed the point. With the publication of a new edition of his classic. The Theory of Economic Progress , the time is ripe to re-evaluate Ayres' contributions. Ayres, like Thorstein Veblen before him, assimilated into economics the findings of other social science and humanistic disciplines, particularly anthropology. Both portrayed clearly the role in the economy of what Veblen called the matter-of-fact and Ayres 'technology,' The understanding of the role of technology and its extension in economic progress , implicit in Veblen, is made explicit by Ayres. Similarly the insight that certain entrepreneurial and financial activities which are ceremonial are non-essential to the technological process and hence dispensable is a contribution by Ayres to the one by Veblen that enables us to distinguish the scientific elements in economic theory from the theological.

An Evaluation of Keynes's Projected Possibilities

Abstract . At the onset of the Great Depression, John Maynard Keynes made some startlingly optimistic predictions about the economic possibilities his grandchildren might face a century later. Within the next 100 years, Keynes proclaimed, technological progress would solve the economic problem facing human beings, individuals would devote themselves to noneconomic pursuits instead, and no one would continue to strive for relative goods. Was Keynes right? This article examines each of Keynes's three main prophecies and concludes that, even though over 75 years have transpired since they were made, and even though they were founded in part on the belief held by most classical economists in the value of technological progress and economic growth, not one of Keynes's predictions has been realized.
