Annuity Values in Defined Contribution Retirement Systems: Australia and Singapore Compared

Annuities promise to play an increasingly important role in countries with national defined contribution retirement systems. In this article we examine life annuities in two countries, Singapore and Australia, each of which has a national mandatory pension program. Exploiting data on annuity pricing and purchase behaviour, we compare the money's worth of life annuity products across these two nations. Our results indicate that, after controlling on administrative loadings, there are important differences in measured adverse selection. Part of the explanation may be due to the different structures of the two countries’retirement systems.     

Patent Breadth, Patent Life, and the Pace of Technological Progress

In active investment climates where firms sequentially improve each other's products, a patent can terminate either because it expires or because a non-infringing innovation displaces its product in the market. We define the length of time until one of these happens as the effective patent life, and show how it depends on patent breadth. We distinguish lagging breadth, which protects against imitation, from leading breadth, which protects against new improved products. We compare two types of patent policy with leading breadth: (1) patents are finite but very broad, so that the effective life of a patent coincides with its statutory life, and (2) patents are long but narrow, so that the effective life of a patent ends when a better product replaces it. The former policy improves the diffusion of new products, but the latter has lower R&D costs.     

Comparing theories to explain e-commerce adoption

E-commerce is a strategy for rapid growth, especially by small and medium sized businesses (SMEs). However, the adoption rate of e-commerce by SMEs in Latin America is still undersized. The authors compare the theory of planned behavior (TPB) and the theory of reasoned action (TRA) using structural equation modeling to determine which is better at predicting e-commerce adoption intentions among 210 SME managers/owners in Chile. Contrary to previous research with American respondents, the study does not find significant differences between the two theories. Thus, academics should select the more parsimonious model (TRA) to study e-commerce adoption issues in developing countries.
