Intellectual property: what do teachers and students know?

As society changes from an industrial to a knowledge era increasing importance and value is being placed on intellectual property rights. Technology teachers need to have pedagogical content knowledge of intellectual property if they are to incorporate it into their learning programmes to enable students to consider how to respect others’ intellectual property rights, how to protect their own ideas and how they can legitimately make use of others’ intellectual property. A survey of technology teachers and a small sample of students was undertaken to ascertain their knowledge of intellectual property and any misconceptions which may exist. The findings reflect an awareness of relevant concepts but confusion between key terms such as patent, copyright and registered design.     

Do all countries follow the same growth process?

We estimate finite-mixture models in which countries are sorted into groups based on the similarity of the conditional distributions of their growth rates. We observe countries growth experiences over the 1970–2000 period and find evidence for a model in which there are two classes of countries, each with its own distinct growth regime. Group membership does not conform to the usual categories used to address parameter heterogeneity such as region or income. We find strong evidence that the quality of institutions and specifically, the degree of law and order, helps to sort countries into different regimes. Once we control for institutional features of the economy, we find no evidence that geographic features such as latitude and being landlocked play a role in determining the country groupings.     

Stable Laws and the Present Value of Fixed Cash Flows

Abstract

In this paper, the authors consider the present value of a series of fixed cash flows under stochastic interest rates. To model these interest rates, they don’t use the common lognormal model, but stable laws, which better fit in with reality. Their main intention is to derive a result for the distribution function of such a present value. However, due to the dependencies between successive discounted payments, the calculation of an exact analytical distribution is impossible. Therefore, use is made of the methodology of comonotonic random variables and the convex ordering of risks, introduced by the same authors in some previous papers.

The present paper starts with a brief overview of properties and features of stable laws, and of the possible application of the concept of convex ordering to sums of risks, which is also the situation for a present value of future payments. Afterwards, the authors show how, for the present value under investigation, an approximation in the form of a convex upper bound can be derived. This upper bound has an easier structure than the original present value, and they derive elegant calculation formulas for the distribution of this bound. Finally, they provide some numerical examples that illustrate the precision of the approximation. Due to the design of the present value and the construction of the upper bound, these illustrations show great promise concerning the accuracy of the approximation.     

Evidence on the cross-country transmission of monetary shocks

The international transmission of monetary shocks between the US and Canada is explored. Focusing on real variables such as consumption, investment, employment, and the bilateral trade balance, along with measures of US and Canadian money, the empirical analysis examines the impact of a monetary shock in one country on real activity in both countries. The long-run analysis provides evidence of cointegration among the variables and suggests that money plays an important role in the equilibrium relationships between the two countries. Variance decompositions and impulse response functions reveal interesting avenues of real transmission in the short run. The short-run analysis provides strong evidence that US monetary shocks affect real activity in both the USA and Canada. The analysis also indicates that Canadian monetary disturbances affect Canadian and US real activity, and that many of these effects are similar in magnitude to the effects of US monetary shocks. The importance of the nominal exchange-rate regime is also discussed.     

Portfolio performance with controlled variables in the Singapore Stock Market

Recently, many stock return ‘anomalies’ have been identified. This leads to increasing agreement among researchers that these anomalies are relevant to enhancing investment performance. This study examines the existence of stock return anomalies on the Stock Exchange of Singapore in the period 1979–87, using a behavioural approach. The results reveal that the impact of anomalies on stock returns is unstable, with the direction of the impact determined by the strength of the stock market. This phenomenon and other observed anomalies may be partially explained by investors' psychology.     

Exploring adoption difficulties in mobile banking services

Factors associated with adopting and resisting mobile banking technologies were investigated among university students in Taiwan. Adoption factors included the belief that mobile banking helps fulfill personal banking needs, provides location-free conveniences, and is cost effective. The primary factors associated with resistance included concerns over system configuration security and basic fees for mobile banking web connections. The theoretical and applied implications of these findings are discussed. Copyright © 2009 ASAC. Published by John Wiley & Sons, Ltd.
