Competitive pressure,innovation and trade protection: Evidence from US patent data

Recent theoretical models have suggested that the relationship between competition and innovation may best be characterised as an inverted‐U shape: firms in industries with low levels of competition are more likely to innovate in the wake of increased competition as they attempt to escape competition, while those in highly competitive industries will decrease innovation in the wake of increased competition as the profit incentive to innovate dissipates. Results from other studies have found positive as well as negative relationships between innovation and competition. In a parallel literature, trade economists have produced conflicting results regarding the impact of trade liberalisation on innovation. One stream of research has shown that increased access to imported intermediate goods increases productivity, suggesting a positive relationship between imports and innovation. Others have hypothesised that firms may use the technology embodied in intermediate inputs as a substitute for domestic innovation. In this paper, we merge these divergent literatures and investigate whether innovation, as measured by the production of patents by US manufacturers, has been impacted by market competition and tariff reductions. Our empirical findings indicate that insulation from imports in the form of higher tariffs on final goods was associated with innovation until the late 1980s, while falling tariffs on intermediate goods appear to have facilitated innovation during the 1990s. We also find evidence of the inverted U‐shaped relationship between market competition and innovation.     

Earnings inequality and unemployment in South Africa

Unemployment and earnings inequality have moved together remarkably closely in South Africa in recent years. This article explores the relationship between unemployment and earnings inequality in South Africa, investigating the extent to which changes in unemployment can account for changes in earnings inequality. Static and dynamic decompositions of earnings inequality by employment status reveal the centrality of unemployment in accounting for the both level and trend of earnings inequality. The distribution of employment in the formal and informal sectors is found to be of lesser importance in explaining earnings inequality, as is wage dispersion within each of these categories. The findings point to the central importance of reducing unemployment in South Africa if the extremely high levels of inequality are to be reduced.     

Women's Enterprise and Business Development Lessons from targeted women's programmes in Glasgow

This paper contributes to the debate on gender and small business, examining two women's enterprise policies and three initiatives developed in Glasgow in the mid 1990s. Responding to concerns about the low rate of women's business start-up and growth in Glasgow, local authorities and the Local Enterprise Company developed a number of policy recommendations. Subsequent implementation by local business development agencies was piecemeal and small scale, due in part to the pressures from output related funding, and to the funders' priority for businesses with high growth potential. The most significant women's enterprise initiative has been the establishment of the Wellpark Enterprise Centre, providing a targeted range of integrated services for women's business start-up and growth.     

Toward High Reliability Project Organizing in Safety‐Critical Projects

High reliability organizations claim to be special organizations that have consistently demonstrated safe performance in operating environments, which are simultaneously of high technical complexity, high consequence, and high tempo. This article argues that the literature on high reliability organizing, which emerged through studying day‐to‐day operations in the nuclear industry, air traffic control industry, and U.S. navy aircraft carriers, might hold important lessons for how the project management community can approach the management of safety‐critical projects—projects in which safety is of paramount importance. Its aim is to consider how high reliability organizing might be realized in these safety‐critical projects.     

Strategies for cross-national comparisons: Matching research issues and analysis objectives

Comparisons across different national economies can make a major contribution to understanding the role of entrepreneurial activity and new firm foundings in economic growth and change. At least four cross-national strategies are possible: (1) direct comparisons; (2) historical or time series correlations; (3) comparison of cross-market analyses; or (4) comparison of cross-regional analyses. The distinctive value of cross-regional analyses is considered and illustrated with a comparison of the effects of manufacturing births on economic growth in the U.S. and Japan.Original research on the U.S. discussed in this paper is from projects, conducted with Professor Wilbur Maki of the University of Minnesota, sponsored by the U.S. Small Business Administration (contract SBA 3067-OA-88) and the Rural Poverty and Resources Program of the Ford Foundation. Professor Yoshio Sato of Keio University (Tokyo) provided the data on Japan.     

Subsidizing rent-seeking: Antidumping protection and the Byrd Amendment

This paper argues that a recent U.S. law, which distributes the tariff revenue resulting from successful antidumping petitions to firms that supported the petitions, increases the amount of antidumping protection requested by U.S. firms in two ways. First, by increasing the total benefits accruing to industries filing successful petitions, the law subsidizes rent-seeking. Second, by awarding these subsidies only to those firms that actively support the petition, it mitigates the free rider problem traditionally associated with collective actions. Empirical results provide strong evidence that industries have filed more antidumping petitions under the new law. Moreover, the average proportion of firms in the industry filing these petitions increased under the law, suggesting that the law at least partially alleviates free riding incentives.     

Consumer preference among fluid milks: low‐fat vs. high‐fat milk consumption in the United States

The present study uses data from the Continuing Survey of Food Intakes by Individuals 1994–1996, 1998 in order to analyse milk consumption by type, specifically high‐fat milk vs. low‐fat milk. Whereas trend analysis displays an overall increase in low‐fat milk consumption over the last few decades in the United States, a number of individuals still consume high‐fat milk varieties, and overall dietary intakes have yet to achieve recommended levels. In light of recent research regarding fat intakes, it is important to understand what factors might cause consumers to purchase high‐fat options given the number of low‐fat options available in the market. Through the use of Logistic regression, key socio‐economic and demographic variables are analysed in order to determine their impacts on the probability of consuming low‐fat milk vs. high‐fat milk. The results indicate that a number of factors do influence probability of low‐fat milk consumption as compared with high‐fat milk consumption. Most notably, probability of low‐fat milk consumption appears to be positively related to age, education level, and income level. African Americans and other minorities had a lower probability of consuming low‐fat milk when compared with White people in the sample population. Also, those respondents designated as low income or living in the South were less likely to consume low‐fat milk.     

Sustainable development and profit? A sensemaking perspective on hybrid organisations and their founders

This article explores the sensemaking process of the individual entrepreneurs behind hybrid organisations that seek to both initiate environmental/social change and also generate profit. The work sheds light on how founders of six such organisations set-up initially in between 1978 and 1991 make sense of themselves and their firm and how this impacts on their business strategies. We examine the life-stories of these individuals to illuminate their perspectives on their experiences, motives and values. We suggest that both ambition and altruism motivate individuals to become involved in these firms, echoing the paradox of firms seeking both social change and value creation. The work enhances our understanding of both sensemaking theory and success factors for hybrid organisations and strategizing more broadly.     

A Case of Mistaken Identity? Measuring Rates of Improved Seed Adoption in Tanzania Using DNA Fingerprinting

Studies of improved seed adoption in developing countries are almost always based on household surveys and are premised on the assumption that farmers can accurately self-report their use of improved seed varieties. However, recent studies suggest that farmers’ reports of seed varieties planted, or even whether the seed is local or improved, are sometimes inconsistent with the DNA fingerprinting results of those crops. We use household survey data from Tanzania to test the alignment between farmer-reported and DNA-identified maize seed types planted. In the sample, 70% of maize seed observations are correctly reported as local or improved, while 16% are type I errors (falsely reported as improved) and 14% are type II errors (falsely reported as local). Type I errors are more likely to have been sourced from other farmers, rather than formal channels. An analysis of input use, including seed, fertiliser, and labour allocations, reveals that farmers tend to treat improved maize differently, depending on whether they correctly perceive it as improved. This suggests that errors in farmers’ seed type awareness may translate into suboptimal management practices. The average yield of seed that is correctly identified as improved is almost 700 kg per hectare greater than that of type I errors. This indicates that investments in farmers’ access to information, seed labelling, and seed system oversight are needed to complement investments in seed variety development.
