Examining the growth patterns of Brazilian cities

The share of urban population in Brazil increased from 58 to 80 percent between 1970 and 2000 and all net population growth over the next 30 years is predicted to be in cities. This paper explores population growth and its implications for economic dynamics and income generation among 123 urban agglomerations. Incomes are higher in larger agglomerations and in the South, but there is some indication of regional convergence with higher rates of income growth in poorer areas. In particular, agglomerations in the North and Central-West are growing faster than the more established urban centers in the South. Economic dynamics point to a process of increased diversification among larger cities, and greater specialization among medium-sized agglomerations. In bigger centers there is a trend toward deconcentration toward the periphery. The paper provides a simple analysis of correlates of labor supply, as measured by population growth and economic productivity, which is proxied by changes in per capita income.

Managing ubiquitous eco cities: the role of urban telecommunication infrastructure networks and convergence technologies

A successful urban management system for a Ubiquitous Eco City requires an integrated approach. This integration includes bringing together economic, socio-cultural and urban development with a well orchestrated, transparent and open decision making mechanism and necessary infrastructure and technologies. Rapidly developing information and telecommunication technologies and their platforms in the late 20th Century improves urban management and enhances the quality of life and place. Telecommunication technologies provide an important base for monitoring and managing activities over wired, wireless or fibre-optic networks. Particularly technology convergence creates new ways in which the information and telecommunication technologies are used. The 21st Century is an era where information has converged, in which people are able to access a variety of services, including internet and location based services, through multi-functional devices such as mobile phones and provides opportunities in the management of Ubiquitous Eco Cities. This paper discusses the recent developments in telecommunication networks and trends in convergence technologies and their implications on the management of Ubiquitous Eco Cities and how this technological shift is likely to be beneficial in improving the quality of life and place. The paper also introduces recent approaches on urban management systems, such as intelligent urban management systems, that are suitable for Ubiquitous Eco Cities

NAFTA at 20: Overview and Trade Effects

[Excerpt] The North American Free Trade Agreement (NAFTA) has been in effect since January 1, 1994. Signed by President George H.W. Bush on December 17, 1992, and approved by Congress on November 20, 1993, the NAFTA Implementation Act was signed into law by President William J. Clinton on December 8, 1993 (P.L. 103-182). NAFTA continues to be of interest to Congress because of the importance of Canada and Mexico as U.S. trading partners, and also because of the implications NAFTA has for U.S. trade policy. This report provides an overview of North American trade liberalization before NAFTA, an overview of NAFTA provisions, the economic effects of NAFTA, and policy considerations

Innovation in Services - Theoretical Approach

The aim of this article is to present the evolution of theoretical studies on service innovation. The author also attempts to put these different approaches to service innovation into order and to indicate the possible forms of service innovation that emerge from these researches. In further part of the article the issue of the availability of statistical data and its relevance to the possible forms of service innovation, as well as some changes that has been implemented recently in order to improve this relevance, are discussed.Celem artykułu jest przedstawienie ewolucji teoretycznych badań nad innowacjami w usługach. Autorka podejmuje również próbę uporządkowania różnych podejść do kwestii innowacji usługowych oraz wskazać możliwe formy tych innowacji, wyłaniające się z analizowanych badań. W dalszej części artykułu, podejmowana jest kwestia dostępności danych statystycznych oraz ich adekwatności, jeśli chodzi o możliwość zastosowania do analizy różnych form innowacji usługowych. Omawiane są również wprowadzone ostatnio zmiany, mające na celu poprawę adekwatności tych danych

The North American Free Trade Agreement (NAFTA)

[Excerpt] The North American Free Trade Agreement (NAFTA) has been in effect since January 1, 1994. NAFTA was signed by President George H. W. Bush on December 17, 1992, and approved by Congress on November 20, 1993. The NAFTA Implementation Act was signed into law by President William J. Clinton on December 8, 1993 (P.L. 103-182). NAFTA continues to be of interest to Congress because of the importance of Canada and Mexico as trading partners, and because of the implications NAFTA has for U.S. trade policy under the Administration of President Donald J. Trump. During his election campaign, President Trump stated his desire to renegotiate NAFTA and that he would examine the ramifications of withdrawing from the agreement once he entered into office. He has also raised the possibility of imposing tariffs or a border tax on products from Mexico. This report provides an overview of North American market-opening provisions prior to NAFTA, provisions of the agreement, economic effects, and policy considerations

Energy-intensity developments for 19 OECD countries and 51 sectors

This paper presents stylized facts on energy-intensity developments for 19 OECD countries and 51 sectors over the period 1980âËâ2005. A principal aim of this paper is to introduce and discuss a new database that combines the recently launched ‘EU KLEMS Growth and Productivity Accounts’ with physical-energy data from the International Energy Agency (IEA). We do so by means of an empirical analysis consisting of the following components at various levels of sectoral detail. First, we document per country the growth rates of energy use, value added and energy intensity (i.e. the ratio of energy use to value added). Second, we compare levels of energy intensity across countries and analyze the evolution of the observed cross-country differences over time. Third, by means of a decomposition analysis we calculate for each country to what extent aggregate energy-intensity trends can be explained from, respectively, shifts in the underlying sectoral structure and efficiency improvements within individual sectors. Finally, we identify issues and areas of research within the field of energy economics where these data may be applied fruitfully.
