Artificial decision-making and artificial ethics: A management concern

Expert systems are knowledge-based information systems which are expected to have human attributes in order to replicate human capacity in ethical decision making. An expert system functions by virtue of its information, its inferential rules, and its decision criteria, each of which may be problematic. This paper addresses three basic reasons for ethical concern when using the currently available expert systems in a decisions-making capacity. These reasons are (1) expert systems' lack of human intelligence, (2) expert systems' lack of emotions and values, and (3) expert systems' possible incorporation of intentional or accidental bias. For these reasons artificial ethics seems to be science fiction. Consequently, expert systems should be used only in an advising capacity and managers should not absolve themselves from legal and ethical responsibility when using expert systems in decision making.Omar E.

PPP in the medium run: The case of Norway

Existing studies generally reject purchasing power parity (PPP) on data sets from countries that have been affected by large real shocks, including Norway. However, we offer strong evidence of PPP between Norway and its trading partners during the post-Bretton Woods period, in which the Norwegian economy has experienced numerous real shocks such as discoveries of large petroleum reserves and oil price shocks. In particular, the behavior of the Norwegian real and nominal exchange rates appears remarkably consistent with the PPP theory. Moreover, convergence towards PPP is relatively rapid; the half-life of a deviation from parity is just about 1.5 years. We show that such deviations are primarily eliminated by adjustments in the nominal exchange rate and we offer some explanations for the relatively rapid convergence towards PPP.     

BOOK REVIEW

Using panel data methods to analyze data from 14 Latin American countries from 1978 to 2003, this paper empirically examines the links between foreign direct investment (FDI), local conditions, and economic growth. The results suggest that FDI plays an important role in contributing to economic growth. However, the effect of FDI on economic growth is dependent on host economy–based conditions. The empirical results from this study show that there is a positive interaction effect of FDI with technology gap and a negative interaction effect of FDI with the level of school attainment on economic growth. Furthermore, the empirical results from the FDI equation suggest that inflation, trade, school attainment, and telephone lines are the most determinant of location decisions for foreign investors. To explore the relationship between FDI and economic growth further, this paper examines Granger-causality between FDI and economic growth. Our empirical evidence shows that the direction of causality is from economic growth to FDI and not the reverse for Asian countries. Therefore, the causal link between FDI and economic growth is unidirectional. We also provide evidence that the link between FDI and economic growth is bidirectional for Latin American countries, which indicates that economic growth initially could attract more FDI, which, in turn, would then result in accelerated economic growth.     

Weak-Form Market Efficiency of the Nigerian Stock Market in the Context of Financial Reforms and Global Financial Crises

The weak-form efficient market hypothesis for the Nigerian Stock Market (NSM) is explored using different statistical tests. The analyses use overall stock market returns collected over the period 2000–2010. It is shown that the NSM is not weak-form efficient which questions the benefits of the 2004 financial reforms. It is also shown that the degree of market inefficiency varies across the periods corresponding to the financial reforms and 2007 global financial crisis, for daily and monthly returns. The results are important to security analysts, investors, and security exchange regulatory agencies in their investment, stock market development, and policy-making decisions.     

Income and Fiscal Incidence by Age and Gender: Some Evidence from New Zealand

With many fiscal policies likely to have quite different age/gender incidences, this paper examines age and gender dimensions of income distribution and fiscal incidence in New Zealand using Household Economic Survey data for 2010. Applying, and testing, an intra‐household income sharing rule, our evidence suggests strong life‐cycle and gender aspects to fiscal incidence. Net tax liabilities are found to be low and negative, at younger and older ages but positive during much of the “working age.” Notwithstanding considerable within‐gender heterogeneity, women are found on average to have systematically and persistently lower net fiscal liabilities than men, especially at older ages.     

Sustainable fisheries development in the tropics: trawlers and licence limitation in Malaysia

Sustainable fisheries development requires sound fisheries management. Area licence limitation programmes may form the cornerstone for most tropical multispecies fisheries management programmes. An empirical analysis of Peninsular Malaysian fishing trawlers is used to design an area licence limitation programme that conforms to the multiproduct production technology, and cost and revenue structures to best accommodate condtions of asymmetric information between the regulator and fishing vessels.     

Developing country fisheries and technical efficiency: the Java Sea purse seine fishery

The analysis of technical efficiency in developing country agriculture is well established but has been overlooked for developing country commercial marine fisheries. Policies raising technical efficiency in agriculture are viewed as uniformly positive but are a mixed blessing in fisheries due to the open-access property right and common-pool resource. This study explores this contradiction and policies aimed to promote sustainable development and management of renewable common pool resources through a case study of the Java Sea purse seine fishery. Season of the year rather than fisher or vessel characteristics primarily determines technical efficiency. The results are contrasted with developing country agriculture and conclusions drawn for fisheries development strategies.     

Peginterferon beta-1a versus other self-injectable disease-modifying therapies in the treatment of relapsing-remitting multiple sclerosis in Scotland: a cost-effectiveness analysis

Aims: Peginterferon beta-1a 125?mcg administered subcutaneously every 2 weeks, a new disease-modifying therapy (DMT) for relapsing-remitting multiple sclerosis (RRMS), was approved in January 2015 by the Scottish Medicines Consortium. This study assesses long-term clinical and economic outcomes of peginterferon beta-1a compared with other self-injectable DMTs (interferon beta-1a [22?mcg, 30?mcg, and 44?mcg], interferon beta-1b, and glatiramer acetate 20?mg) in the treatment of RRMS, from the National Health Service and Personal Social Services perspective in Scotland.

Methods: A previously published, validated Markov cohort model was adapted for this analysis. The model estimates changes in patient disability, occurrence of relapses, and other adverse events, and translates them into quality-adjusted life years and costs. Natural history data came from the ADVANCE trial of peginterferon beta-1a, the London Ontario (Canada) database, and a large population-based MS survey in the UK. The comparative efficacy of each DMT vs placebo was obtained from a network meta-analysis. Costs (2015 British Pounds) were obtained from public databases and literature. Clinical and economic outcomes were projected over 30 years and discounted at 3.5% per year.

Results: Over 30 years, peginterferon beta-1a was dominant compared with interferon beta-1a (22, 30, and 44?mcg), and interferon beta-1b, and cost-effective compared with glatiramer acetate 20?mg. Results were most sensitive to variations in each DMT’s efficacy and acquisition costs. Deterministic and probabilistic sensitivity analyses confirmed the robustness of the results.

Limitations: The impact of improved adherence with peginterferon beta-1a on clinical and economic outcomes and the impact of subsequent DMTs after treatment discontinuation were not considered. Oral and infused DMTs were not included as comparators.

Conclusion Long-term treatment with peginterferon beta-1a improves clinical outcomes, while its cost profile makes it either dominant or cost-effective compared with other self-injectable DMTs for the treatment of RRMS in Scotland.     

China??s banking system, market structure, and competitive conditions

This paper presents an empirical assessment of the market structure and the competitive conditions of the Chinese banking sector. We applied the Panzar-Rosse H-statistic on the data collected from a panel including 16 most significant Chinese banks for the period 2004–2007. Equilibrium tests and the competitive conditions tests were applied on the data. From the pooled regression in the whole period, we found that the banking sector in China for 2004–2007 was monopolistically competitive. We also show that the Chinese banks were not able to achieve high records of profitability in monopolistically competitive markets.
