South Africa in the Australian mirror: per capita real GDP in the Cape Colony,Natal, Victoria,and New South Wales, 1861–1909

This article compares the real GDP per capita of the Cape Colony and Natal between 1861 and 1909 with that of Australia's two most developed colonies, Victoria and New South Wales. Estimates of European and non‐European GDP per capita for both South African colonies are also provided. Together, this information allows for the first time an evaluation of the growth performance of these important parts of the South African economy in the colonial era. The article concludes that South African performance in this period was stronger than often assumed and that by the beginning of the twentieth century European South Africans, now more fully integrated into a British World economy, operated at a level of GDP per capita that matched and in some places may have exceeded that of Australians. Non‐European South Africans, however, did not share in these same advances.     

Technology-based design and sustainable economic growth

This paper seeks to analyze how design creates economic value. The literature on knowledge-based economic development has primarily focused on innovation as the analytical lens, whereas design is the original action that leads to innovation. Despite the fundamental importance of design, existing design research has offered few insights and little guidance for national strategies due to the lack of focus on and analysis of design in an economic context. This paper addresses such gaps by linking design research and economic development theory. We first elaborate on the relationship among design, invention and innovation, describing the necessity of design activity for invention and innovation. Our analysis of the fundamental characteristics of design across contexts sheds light on the strategic importance of the accumulative nature of technology-based design for sustaining economic growth. Through the lens of technology-based design, we further quantitatively compare Singapore and three similarly-sized countries (South Korea, Finland and Taiwan). Based upon interview data, we also qualitatively examine Singapore's national strategy focusing on design. The quantitative and qualitative results align well with the Singaporean government's use of design as a strategic lever to pursue innovation-driven economic growth, and also reveal its achievements and shortfalls which indicate possible directions for strategic adjustment.

How many singularities are near and how will they disrupt human history?

This paper reviews a large number of approaches that have been used for considering technologically driven profound societal change. We agree with Vinge's suggestion for naming events that are “capable of rupturing the fabric of human history” (or leading to profound societal changes) as a “singularity”. This is a useful terminology especially since a mathematically rigorous singularity seems impossible for technological and related societal change. The overview of previous work is done within the context of a broader look at the role of technological change within human history. The review shows that a wide variety of methods have been used and almost all point to singularities in the present century particularly in the middle of the century. The diversity of the methods is reassuring about the potential robustness of these predictions. However, the subjectivity of labeling events as singularities (even well studied past events) is a concern about all of the methods and thus one must carefully pause when relying in any way on these predictions. The general lack of empirical research in this area is also a concern.Quantitative considerations (by proponents and opponents) about past singularities or future singularities often confound two types of metrics. The first type is essentially related to diffusion of technologies (or bundles of technologies) where the logistic curve is empirically well established as the proper time dependence. The second type of metric is for technological capability where hyper-exponentials are empirically well established for their time dependence. In this paper, we consider two past singularities (arguably with important enough social change to qualify) in which the basic metric is alternatively of one type or another. The globalization occurring under Portuguese leadership of maritime empire building and naval technological progress is characterized by a metric describing diffusion. The revolution in time keeping, on the other hand, is characterized by a technological capability metric. For these two cases (and thus robust to the choice of metric type), we find that:

• • 

  People undergoing profound technologically-driven societal change do not sense a singularity.

• • 

  The societal impacts depend in complicated ways on human needs, institutional variables and other more uncertain factors and thus are particularly hard to project;

• • 

  The societal impact is apparently not determined by the rate of progress on either type of metric or by projections to mathematical points with either kind of metric. This finding supports the existing concept that social change due to technology is a more holistic phenomenon than can be characterized by any technical metric.

In the final section, we use these empirical findings as the basis for exploring the possibilities for and nature of future singularities. In this we speculate that the potential for a future strong singularity based upon computational capability does not appear particularly probable but that one may already be occurring and is not fully noticed by those (us) going through it. Other possible 21st century singularities (life extension and fossil fuel elimination are two examples considered) may also be already underway rather than waiting for the predicted mid-century changes.     

Declining Industries and Persistent Tariff Protection

The paper uses a political economy framework to explain the empirical observation that trade protection is persistent. The assumptions that are shown to generate endogenous tariff persistence in the model are quite plausible: agents are uncertain about future prices, tariffs are affected by political pressure, and producers of the import–competing good own sector–specific human capital that may be lost if they exit the industry. The model also reveals that, under the conditions listed above, industries decline gradually in response to a price shock even when producers do not face increasing costs of adjustment.     

Four Simple Tests of Campaign Contributions and Trade Policy Preferences

This paper uses campaign contribution data to examine trade policy preferences among political action committees. With perfect factor mobility, as the Heckscher–Ohlin (HO) model assumes, interest group trade positions should depend on their factor of production but not on their industry. We show, consistent with the 2 × 2 HO model, that capital groups consistently back representatives supporting trade liberalization while labor groups favor protectionists. Unlike previous work, we also measure the variation in trade policy preferences within capital and labor groups. We find evidence that the industry net export position significantly affects labor unions' trade policy preferences. Industry characteristics have no impact on capital group lobbying. The former result suggests that empirical analyses of labor PAC contributions that exclude industry characteristics may be misspecified.     

Do Professors’ Opinions Affect Students?

This paper estimates the effect that professors’ opinions have on changes in student opinions during introductory economics classes. The paper shows that students are more likely to change their opinion during the course of the semester if their initial response differs from that of the professor, and this result emerges even after controlling for students’ tendency to move toward the consensus opinion held by all the economics professors. Students are also more likely to change their opinions if they differ from the opinions of their classmates, and the estimates show that in the aggregate, classmate opinions matter more than professor opinions do. The data also show that students choose which section to attend at least partly based on how closely their pre-class opinions match those of the professor. These results have important implications for both heterodox and orthodox economists.     

Application of the DIERS methodology to the study of runaway polymerization: Validation of the DIERS methodology using blow-down tests

The Design Institute for Emergency Relief Systems (DIERS) and more recently the DIERS Users Group have been investigating various aspects of emergency relief for more than 12 years. The DIERS programs have given rise to an in-depth understanding of the basic mechanism of how runaway thermal reactions are safely vented. In concert with the development of the understanding of the venting mechanism, DIERS also developed experimental procedures and computational techniques for estimating emergency vent sizes.
