Some empirical evidence on offender time discount rates

The conventional wisdom is that offenders have very high discount rates not only with respect to income and fines but also with respect to time incarcerated. These rates are difficult to measure objectively and the usual approach is to ask subjects hypothetical questions and infer time preference from their answers. In this article, we propose estimating rates at which offenders discount time incarcerated by specifying their equilibrium plea, defined as the discount rate, which equates the time and expected time spent in jail following a guilty plea and a trial. Offenders are assumed to exhibit positive time preference and discount time spent in jail at a constant rate. Our choice of sample is interesting because the offenders are not on bail, punishment is not delayed and the offences are planned therefore conforming to Becker’s model of the decision to commit a crime. Contrary to the discussion in the literature, we do not find evidence of consistently high time discount rates, and therefore cannot unequivocally infer that the prison experience always results in low levels of specific deterrence.

The energy consumption - real GDP nexus revisited : empirical evidence from 93 countries

In this paper, we analyse the long-run relationship between energy consumption and real GDP for 93 countries. We find mixed results on the impact of energy consumption on real GDP, with greater evidence at the country level supporting energy consumption having a negative causal effect on real GDP. For the G6 panel of countries, we find significant evidence that energy consumption negatively Granger causes real GDP. This means that for countries where energy consumption has a negative long-run causal effect on real GDP, energy conversation policies should not retard economic growth. We identify these countries and regional panels. We argue that these countries/regions should play a greater role in reducing carbon dioxide emissions.

An empirical analysis of colour image segmentation using fuzzy c-means clustering

In this paper, an empirical analysis to examine the effects of image segmentation with different colour models using the fuzzy c-means (FCM) clustering algorithm is conducted. A qualitative evaluation method based on human perceptual judgement is used. Two sets of complex images, i.e., outdoor scenes and satellite imagery, are used for demonstration. These images are employed to examine the characteristics of image segmentation using FCM with eight different colour models. The results obtained from the experimental study are compared and analysed. It is found that the CIELAB colour model yields the best outcomes in colour image segmentation with FCM.

An empirical analysis of the effects of the exchange rate on Canadian tourism

The effects of depreciation of the Canadian dollar on the Canadian tourist industry are estimated, and it is shown that the exchange rate had a modest impact in attracting U. S. visitors to Canada. However, the favorable exchange rate effects seem to be offset by other factors.

Profile information and business outcomes of providers in electronic service marketplaces : an empirical investigation

Electronic service marketplaces (ESMs) have become major exchange platforms for the online outsourcing of different services – especially software development – to providers. Provider profiles on ESMs encompass extensive information regarding the activities and transactions of providers and they are a main source of information for customers. Such profile information significantly facilitates the relationship development between customers and providers. The existing literature has focused on the impact of the ratings of providers, but so far has not investigated the impact of the other available profile information. Building on the integrated information response model, this study investigates how information presented by providers as well as information provided by the ESM influences the business outcomes of the providers. Based on data collected from one of the major ESMs, we found that profile information indeed has a significant impact on the business outcomes of providers.

What drives the adoption of electronic markets in Australian small-and-medium sized enterprises? – an empirical study

This paper reports a study of the critical determinants for adopting electronic markets (e-Market) in Australian small-and-medium sized enterprises (SMEs) within the technology-organization-environment (TOE) framework. Structural equation modelling and logistic regression are used for identifying the critical determinants for the adoption of e-Markets by Australian SMEs through testing a proposed conceptual model and proposing an alternative model. This study contributes to existing research by enriching an understanding of the critical determinants of adopting an e-Market in Australian SMEs and by providing a validated model for the interrelationships of the determinants in technology adoption.

The effects of website quality on adoption of e-government service : an empirical study applying UTAUT model using SEM

In today’s global age, e-government services have become the main channel for online communication between the government and its citizens. They aim to provide citizens with more accessible, accurate, real-time and high quality services. Therefore, the quality of government websites which provide e-services is an essential factor in the successful adoption of e-government services by the public. This paper discusses an investigation of the effect of the Website Quality (WQ) factor on the acceptance of using e-government services (G2C) in the Kingdom of Saudi Arabia (KSA) by adopting the Unified Theory of Acceptance and Use of Technology (UTAUT) Model. Survey Data collected from 400 respondents were examined using the structural equation modelling (SEM) technique and utilising AMOS tools. This study found that the factors that significantly influenced the Use Behaviour of e-government services in KSA (USE) include Performance Expectancy (PE), Effort expectancy (EE), Facilitating Conditions (FC) and Website Quality (WQ), while the construct known Social Influence (SI) did not. Moreover, the results confirm the importance of quality government websites and support systems as one of the main significant and influential factors of e-government services adoption. The results of this study can be helpful to Saudi’s governmental sectors to adjust their corporate strategies and plans to advance successful adoption and diffusion of e-government services (G2C) in KSA.

Enabling innovation in information technology outsourcing : an empirical study

Information technology outsourcing has become a pervasive and important phenomenon in business organizations and there is substantial evidence about its benefits and pitfalls. Initially, firms used outsourcing as a way to lower costs, gain access to expertise and focus on core activities. Recently, there is a shift in focus and more firms are outsourcing to attain innovative products and services. However, current research is still unclear about how innovation can be achieved through outsourcing. Drawing predominantly from the dynamic capability theory, the objective of this paper is to explore how absorptive capacity unfolds as a process within and between firms when client firms outsource their information technology services with expectations of innovation generation. In this paper, we propose a research model that links absorptive capacity to innovation generation. We draw on three case studies to focus on how absorptive capacity, as a process, impacts innovation generation. Results show that assimilation and transformation stages are critical in generating radical innovation while acquisition and exploitation play a key role in incremental innovation. The implications of these findings for both researchers and practitioners are discussed.

Effectiveness of e-recruiting : empirical evidence from the Rosebank business cluster in Auckland, New Zealand

This article focuses on the background of the 'conventional' or 'old' way of recruiting, it reviews different 'new' ways; e-recruiting and its effectiveness; advantages such as accessibility and disadvantages such as transgression of some legislation in e-recruiting and the impact it has on management. Face-to-face interviews were conducted with 102 companies within that population. A 36- question questionnaire was used and we employed random stratified cluster sampling. Research done in Auckland's Rosebank Business Precinct (New Zealand) revealed that for certain job categories e-recruitment is effective. E-recruitment is revolutionising the way employers hire employees. Some implications for managers are pointed out such as the need to be trained for these changes; it can save a lot of money on advertisements; the savings could be used to develop careers or training for employees. The recommendations suggest that the HR objectives have to align with the organisational objectives to ensure that they recruit, select and employ the right candidate for the right job. A flow diagram for e-recruiting was developed by the authors for use by employers.
