The Geography of Innovation in China and India

The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.

“一带一路”框架下的中拉绿色产品贸易:特征、比较优势与出口潜力

在“双循环”背景下,加强“一带一路”建设对中国深化对外开放意义重大,促进中拉绿色贸易符合双方利益,可为“一带一路”延伸至拉美创造新的合作增长点。本文使用2002年至2018年的货物贸易数据,分析了中拉共建“一带一路”过程中中拉绿色产品贸易的特征和趋势,并重点研究了中国绿色产品对拉美的出口潜力。通过使用双边显示性比较优势指数和出口潜力矩阵,文章发现,在现有的中拉货物贸易结构中,绿色产品贸易所占比重较低,贸易对象高度集中,但随着双方经贸合作的全面深化、特别是“一带一路”延伸至拉美,双边绿色产品贸易金额和种类都在稳定上升。尽管中国绿色产品在拉美市场面临着地理距离遥远、市场竞争激烈等客观困难,但中国的优势产品已成功出口到拉美。中国的出口潜力更多地取决于拉美地区的市场需求,一旦拉美对绿色产品的需求提升,那么中国就具备进一步扩大向拉美出口该类产品的潜力。此外,出口潜力矩阵也找出了部分对拉美市场而言具备不可替代性的中国产品,这也将成为中国潜在的对拉出口重点绿色产品。

School Kids and Oil Rigs: Two More Pieces of the Post‐Katrina Puzzle in New Orleans

Shortly after Hurricane Katrina's landfall in August 2005 and the reports of rampant looting of businesses in the city, we became curious about the extent of Katrina looting as compared to that after other major storms that hit New Orleans in 1947 and in 1965. Using burglary as a proxy variable for looting, we discovered that the burglary rates in the month before and the month after Katrina were significantly higher than those before and after the other two hurricanes. We then investigated the socioeconomic conditions in the city in an effort to explain these numbers. Population loss and high unemployment rates, coupled with a decline in high‐paying manufacturing jobs and an increase in low‐wage food and hotel service jobs generated severe economic inequality in the city that exacerbated the situation created by Katrina. Our current analysis of the impact of public school desegregation and the oil bust suggests that both events contributed to population loss and the increase in low‐wage jobs prior to the storm. We believe that this type of research can assist in the recovery of New Orleans by providing an understanding of the city's pre‐Katrina social and economic conditions and make clearer which post‐Katrina changes are desirable.

Recontextualising a strategic concept within a globalising company: a case study on Carlsberg's ‘Winning Behaviours’ strategy

A corporate strategy is often formulated on the executive floor at headquarters. However, in order to make it live in an organisation, middle management and employees must be involved and make sense of it. These actors thus contribute to, participate in and enact the strategy in processes where it may take on new meanings and forms. This article investigates how ‘Winning Behaviours’, a strategic concept developed on the initiative of top management at the Carlsberg Group in order to improve global integration in the multinational organisation, was recontextualised. It draws upon interviews and observations as well as documents collected at the company headquarters in Denmark and in its subsidiaries in China and Malaysia. Here, expatriate and local managers tried to give sense to the Winning Behaviours in various ways, and employees brought their own local leadership ideals into play when they tried to make sense of the preferred behaviours and turn them into daily practices. The process of creating a new strategic concept and making it live in other sociocultural contexts was facilitated by headquarters staff in the Human Resources and Communications departments, who thus played an important role as change agents in the ‘glocal’ strategy process.     

Human resource management and industrial relations in multinational corporations in and from China: Challenges and new insights

The purpose of this article is to provide an overview on the state of research in the field in human resource management (HRM) issues in multinational corporations (MNCs) in and from China. We integrate previous studies from multiple disciplines to articulate the contextual importance of research on this topic, and suggest overarching themes to expand the field of research. HRM research in the intercultural, interinstitutional context of MNCs in and from China has the potential to provide contextualized insights for longstanding debates in the field such as HRM standardization versus localization and convergence versus divergence and contextual factors behind these patterns. To this end, we call for future research to center on the changing cultural, institutional, technological, and globalization context in understanding HRM and industrial relations issues in these MNCs. Practically, knowledge in this area can help global managers and top management teams in multinational organizations navigate various context complexity, foster more productive coordination and cooperation across borders, and gain legitimacy and MNCs in and from China additional competitive edge in the global marketplace.

Measuring a boom and bust: The Sydney housing market 2001–2006

The Sydney housing market peaked in 2003. The period 2001–2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in broad agreement regarding the timing of the turning point in the housing market, some important differences also emerge. In particular, we find evidence of sample selection bias in our hedonic and repeat-sales data sets (with the former focusing more on better quality dwellings and the latter more on lower quality dwellings). These sample selection biases could in turn cause bias (in opposite directions) in our hedonic and repeat-sales indexes. Median indexes may likewise be biased as a result of an apparent decline in the average quality of dwellings sold in the latter part of the sample. We also find evidence of convergence in prices across regions during the boom and divergence in the subsequent bust.

Using extreme value theory to measure value-at-risk for daily electricity spot prices

The recent deregulation in electricity markets worldwide has heightened the importance of risk management in energy markets. Assessing Value-at-Risk (VaR) in electricity markets is arguably more difficult than in traditional financial markets because the distinctive features of the former result in a highly unusual distribution of returns—electricity returns are highly volatile, display seasonalities in both their mean and volatility, exhibit leverage effects and clustering in volatility, and feature extreme levels of skewness and kurtosis. With electricity applications in mind, this paper proposes a model that accommodates autoregression and weekly seasonals in both the conditional mean and conditional volatility of returns, as well as leverage effects via an EGARCH specification. In addition, extreme value theory (EVT) is adopted to explicitly model the tails of the return distribution. Compared to a number of other parametric models and simple historical simulation based approaches, the proposed EVT-based model performs well in forecasting out-of-sample VaR. In addition, statistical tests show that the proposed model provides appropriate interval coverage in both unconditional and, more importantly, conditional contexts. Overall, the results are encouraging in suggesting that the proposed EVT-based model is a useful technique in forecasting VaR in electricity markets.     

A Conversation with James O. Ramsay

Jim Ramsay was born on September 5, 1942, in Prince George, British Columbia. He pursued undergraduate studies at the University of Alberta, where he completed a BEd in 1964 with a major in English and a minor in mathematics. He then specialized in statistics and psychometry, earning a PhD in psychology from Princeton University in 1966. After holding a temporary lectureship in the Department of Psychology at University College London for one year, he joined the Department of Psychology at McGill University, where he rose through the academic ranks. He was chair of his department from 1986 to 1989 and spent sabbatical leaves in Cambridge, Grenoble, and Toulouse. He was named professor emeritus upon his retirement in 2007. Jim is the author of four influential books and over 100 peer‐reviewed articles in statistical and psychometric journals. He developed much of the statistical theory behind multidimensional scaling and is widely recognized as the founder of functional data analysis. Three of his papers were read to the Royal Statistical Society, and another won The Canadian Journal of Statistics 2000 Best Paper Award. The Statistical Society of Canada (SSC) awarded him a Gold Medal for research in 1998 and an honorary membership in 2012. Jim was president of the Psychometric Society in 1981–82 and president of the SSC in 2002–03. The following conversation took place at Jim's home in Ottawa, Ontario, on March 14 and April 4, 2012.     

Corroborating social media echelon in cancer research

Worldwide medical facilities differ, and for this reason, the causes of death can vary. Cancer is considered the second leading cause of death after heart disease worldwide, and the same causes of death are observed in the United States (US). Therefore, the purposes of this study are to explore worldwide research levels in the field of cancer and the social collaboration of researchers and institutions in this field. This article examines the structural patterns of international co-authors and co-institutions in science citation index papers in cancer research. The study uses measures from the social network analysis method, including degree centrality, betweenness centrality, eigenvector centrality, and effectiveness, to investigate the effects of social networks in the area of cancer research. Empirical analysis results identify the US is the most central country, followed by Germany, Italy, France, and China, in terms of co-authored networks in this research field. Institutional analysis results indicate that the University of Milan is at the top in terms of degree centrality. The Gustave Roussy Cancer Campus in France and German University of Düsseldorf occupy the second and fourth positions, respectively. The University of California in Los Angeles and Harvard University, both in the US, are at third and fifth positions, respectively.     

Longitudinal analysis of self-employment follow-through

The Hungarian economy was based on central planning for several decades and in comparison with the dominance of the great organizations that consisted of many smaller units, the role of small-sized enterprises was marginal. The change in the political climate involved recognition of and belief in entrepreneurship and the new legal system increased the opportunity for setting up new enterprises established on private and joint capital. Nevertheless, the changes in the organizational system of companies within the national economy appear to concentrate in time and territory in Northern Hungary. Increasing unemployment inspires the start of numerous enterprises even when the experience of entrepreneurship is missing and, in addition, the inclination towards it. This may result in difficulties and danger and a study of North Hungarian small businesses is therefore useful.

The aim of this research is to examine the position of SMEs in the North Hungarian industrial area, concentrating on questions that can not be answered by means of traditional statistics. Data were collected by surveying questionnaires. The questions referred to the development of SMEs in North Hungary.

Finally, the elements in the economic environment that may hinder or help successful operation of the enterprises were analysed. With the experience gained by our investigation we would like to help in the reinforcement of SMEs working in Northern Hungary.
