Endogenous growth with capital in R&D production functions

[eng] In this paper we claim that capital is as important in the production of ideas as in the production of final goods. Hence, we introduce capital in the production of knowledge and discuss the associated problems arising from the public good nature of knowledge. We show that although population growth can affect economic growth, it is not necessary for growth to arise. We derive both the social planner and the decentralized economy growth rates and show the optimal subsidy that decentralizes it. We also show numerically that the effects of population growth on the market growth rate, the optimal growth rate and the optimal subsidy are small. Besides, we find that physical capital is more important for the production of knowledge than for the production of goods.

R&D poverty traps

In this paper we show that the R&D effort of a country and its economic growth are highly correlated. In order to analyze this relationship, we study the nature of the researching activity. In particular, we focus on the following characteristics of research: the inherent uncertainty of researching, the existence of a wage premium associated to innovative activities, and moral hazard. Assuming that a higher R&D effort translates into a higher R&D success probability, we show that when the R&D success probability is low, the economy is not willing to bear the risk associated to R&D activities. As a consequence, few researchers are hired and the economy stays in an R&D poverty trap, a situation where the economy is stacked in a low growth environment due to the uncertainty associated with the researching activity.

F/OSS to promote vendor independence/avoid lock-in in the enterprise

This paper focuses on the use of FLOSS to promote vendor independence/avoid lock-in in the enterprise. It looks at how FLOSS projects follow open standards, how forking prevents lock-in if a project threatens to migrate to a closed-source strategy and how FLOSS lowers the barrier to entry for SMEs wishing to implement and support software. However it also looks at how the adoption of policies mandating open standards instead of FLOSS and how the success of cloud computing threatens to erode those benefits. It discusses ways in which cloud computing can be adopted in the enterprise without forfeiting those advantages and urge corporate and government policy makers to mandate FLOSS rather than be satisfied with open standards.

De què vas, tio?

My study is based on an ethnography of two groups of young people from working-class neighbourhoods in Barcelona. I was interested in researching the impact of Catalan language policies on the identities of young people of Spanish-speaking immigrant families. I sought to go beyond the constraints of traditional structuralist approaches in Sociolinguistics in order to make my analysis relevant to people working for gender equality, the promotion of the Catalan language, or other social causes. I combine ideas from Bakhtin, Bourdieu, Fairclough, Foucault and Goffman to build a dialectical, historical, process-centred perspective that conceptualises practices in terms of social and political struggles.I analyse young people's peer-group activities in terms of their significance for the construction of gender identities. I propose a variety of forms of masculinity and femininity according to the various ways in which members organised their gender displays in face-to-face interaction.I also show how their use of argot and dialectal Spanish was part of the processes whereby members defined their relationships, constructed particular subject positions in interaction and struggled to legitimate their own values.I explore the meanings constructed through Catalan and Spanish by looking into the code-switching practices of my participants. I analysed their talk in terms of narratives that present particular sequential dramatisations of events for conversational audiences. These narratives follow the expressive intention of the author, and are populated with multiple voices of animated characters. I argue that, in the groups I studied, Catalan was generally not used to animate the voices that were central to the identities of the peer-group, and particularly to masculine identities.In order to contextualise these practices within the wider society, I also look into the processes of language choice in face-to-face encounters. I argue that existing conventions made it difficult for people to find opportunities to speak Catalan. I also pointed to the difficulties that my participants had to find employment, which were particularly acute amongst the more politically aware individuals. I conclude that these young working-class people had little possibilities of investing in more egalitarian forms of identity given their lack of resources and opportunities to develop their identities in other social spaces, such as the workplace.

The effects of unemployment benefits on migration in lagging regions

[spa] En este trabajo se analizan los efectos sobre la movilidad geográfica de una política pública (SIPTEA) que aumenta la protección por desempleo en Extremadura y Andalucía. Utilizando la discontinuidad geográfica en la política estudiada y datos de los Censos de Población de 1981 y 1991 a nivel municipal, se estima el efecto de SIPTEA en el crecimiento de la población y en las probabilidades de emigrar e inmigrar en áreas rurales que experimentan elevadas tasas de paro y de emigración. Los resultados del trabajo indican que la política mitigó estas pérdidas de población aunque los efectos son cuantitativamente moderados. También se exploran los efectos de dicha política en el ámbito laboral, encontrándose un incremento de la tasa del desempleo asociado a la implementación de la política de entre 10 y 13 puntos porcentuales.

Maritime transportation in the Gulf of Finland in 2007 and in 2015

The Gulf of Finland is said to be one of the densest operated sea areas in the world. It is a shallow and economically vulnerable sea area with dense passenger and cargo traffic of which petroleum transports have a share of over 50 %. The winter conditions add to the risks of maritime traffic in the Gulf of Finland. It is widely believed that the growth of maritime transportation will continue also in the future. The Gulf of Finland is surrounded by three very different national economies with, different maritime transportation structures. Finland is a country of high GDP/per capita with a diversified economic structure. The number of ports is large and the maritime transportation consists of many types of cargoes: raw materials, industrial products, consumer goods, coal and petroleum products, and the Russian transit traffic of e.g. new cars and consumer goods. Russia is a large country with huge growth potential; in recent years, the expansion of petroleum exports has lead to a strong economic growth, which is also apparent in the growth of maritime transports. Russia has been expanding its port activities in the Gulf of Finland and it is officially aiming to transport its own imports and exports through the Russian ports in the future; now they are being transported to great extend through the Finnish, Estonian and other Baltic ports. Russia has five ports in the Gulf of Finland. Estonia has also experienced fast economic growth, but the growth has been slowing down already during the past couples of years. The size of its economy is small compared to Russia, which means the transported tonnes cannot be very massive. However, relatively large amounts of the Russian petroleum exports have been transported through the Estonian ports. The future of the Russian transit traffic in Estonia looks nevertheless uncertain and it remains to be seen how it will develop and if Estonia is able to find replacing cargoes if the Russian transit traffic will come to an end in the Estonian ports. Estonia’s own import and export consists of forestry products, metals or other raw materials and consumer goods. Estonia has many ports on the shores of the Gulf of Finland, but the port of Tallinn dominates the cargo volumes. In 2007, 263 M tonnes of cargoes were transported in the maritime traffic in the Gulf of Finland, of which the share of petroleum products was 56 %. 23 % of the cargoes were loaded or unloaded in the Finnish ports, 60 % in the Russian ports and 17 % in the Estonian ports. The largest ports were Primorsk (74.2 M tonnes) St. Petersburg (59.5 M tonnes), Tallinn (35.9 M tonnes), Sköldvik (19.8 M tonnes), Vysotsk (16.5 M tonnes) and Helsinki (13.4 M) tonnes. Approximately 53 600 ship calls were made in the ports of the Gulf of Finland. The densest traffic was found in the ports of St. Petersburg (14 651 ship calls), Helsinki (11 727 ship calls) and Tallinn (10 614 ship calls) in 2007. The transportation scenarios are usually based on the assumption that the amount of transports follows the development of the economy, although also other factors influence the development of transportation, e.g. government policy, environmental aspects, and social and behavioural trends. The relationship between the development of transportation and the economy is usually analyzed in terms of the development of GDP and trade. When the GDP grows to a certain level, especially the international transports increase because countries of high GDP produce, consume and thus transport more. An effective transportation system is also a precondition for the economic development. In this study, the following factors were taken into consideration when formulating the future scenarios: maritime transportation in the Gulf of Finland 2007, economic development, development of key industries, development of infrastructure and environmental aspects in relation to maritime transportation. The basic starting points for the three alternative scenarios were: • the slow growth scenario: economic recession • the average growth scenario: economy will recover quickly from current instability • the strong growth scenario: the most optimistic views on development will realize According to the slow growth scenario, the total tonnes for the maritime transportation in the Gulf of Finland would be 322.4 M tonnes in 2015, which would mean a growth of 23 % compared to 2007. In the average growth scenario, the total tonnes were estimated to be 431.6 M tonnes – a growth of 64 %, and in the strong growth scenario 507.2 M tonnes – a growth of 93%. These tonnes were further divided into petroleum products and other cargoes by country, into export, import and domestic traffic by country, and between the ports. For petroleum products, the share of crude oil and oil products was estimated and the number of tanker calls in 2015 was calculated for each scenario. However, the future development of maritime transportation in the GoF is dependent on so many societal and economic variables that it is not realistic to predict one exact point estimate value for the cargo tonnes for a certain scenario. Plenty of uncertainty is related both to the degree in which the scenario will come true as well as to the cause-effect relations between the different variables. For these reasons, probability distributions for each scenario were formulated by an expert group. As a result, a range for the total tonnes of each scenario was formulated and they are as follows: the slow growth scenario: 280.8 – 363 M tonnes (expectation value 322.4 M tonnes)

Treinta años de cooperación al desarrollo en España: análisis de la continuidad y cambio en las políticas públicas

A partir del análisis de la red de actores (policy network) y de la teoría del equilibrio interrumpido desarrollado por Baumgartner y Jones (1993), en este trabajo se analiza el caso de la política de cooperación al desarrollo de España desde la transición democrática hasta el presente. El objetivo es analizar la continuidad y cambio de esta política desde la perspectiva del análisis de las políticas públicas. Se demuestra que, al igual que en otros casos, la estabilidad más que el cambio caracteriza su evolución. Al mismo tiempo, se señala que las características propias del subsistema político de la cooperación al desarrollo afectan la magnitud y la frecuencia de los cambios en la política.

A utilização de etanol em célula a combustível de óxido sólido

This work reports a review on the status and technical feasibility of the application of ethanol as fuel for Solid Oxide Fuel Cells (SOFC), presenting both external reform and cell with direct utilization of ethanol. Based on this survey, both experimental results and mathematical modeling indicated the technical feasibility of power generation by ethanol SOFC, with cell units producing 450 mW/cm², sufficient for scale up to large stationary plants. The quantitative assessments in the literature show this field to be promising for researchers and private sector investment as well being a strategic technology for government policy in the short and long term.

A discussion of the current world scenario ensues and some perspectives regarding the prospection, market and government policy concerning the rare earth elements in Brazil are given.

A regulamentação dos preços dos planos individuais de saúde

Aggregate price indices measure variations in nominal prices. In this paper, we compare the inflation rates of the general economy and those of the health sector and private health insurance market between 2001 and 2005, based on the indices of Departamento Intersindical de Estatística e Estudos Socioeconômicos, of Fundação Instituto de Pesquisas Econômicas, of Instituto Brasileiro de Geografia e Estatística and IPEADATA database, to the private health insurance readjustment applied by the National Private Health Insurance Agency (ANS). The health sector inflation rate was found stable and inferior to the general one, what would validate applying lower readjustments derived from official price indices.

Partnership, politics and public administration: a case study of the Ontario Ministry of Natural Resources

Efforts to reform the public sector reflect the social, political and economic environment within which government must function. The recent demands by the public for more consensual decision-making, as well as more efficient, effective and responsive public service, have resulted in a number of reform initiatives, including an emphasis on partnership development. The purpose of this thesis is to examine partnership arrangements within the public sector. Specifically, the thesis will assess the value of partnerships and their impact on government by examining six partnership arrangements involving the Ontario Ministry of Natural Resources (OMNR). The OMNR, having recently been awarded the 1992 Institute of Public Administration of Canada Award for Innovative Management, on the theme of partnership development, is being lauded as an example for other government agencies considering similar alliances. The thesis begins by introducing the concept and practice of partnership within the public sector in general and the OMNR specifically. Descriptive analysis of six OMNR partnerships is provided and a number of criteria are used to determine the success of each of these arrangements. Special attention is paid to the political implications of partnerships and to those attributes which appear to contribute to the successful establishment and iii maintenance of partnership arrangements. The conclusion is drawn that partnerships provide the government with an opportunity to address public demands for greater involvement in decision-making while accommodating government's limited financial resources. However, few truly collaborative partnerships exist within the public sector. There are also significant political implications associated with partnerships which must be dealt with both at the political and bureaucratic levels of government. Lastly, it is argued that while partnerships within the OMNR are experiencing some difficulties, they constitute a genuine attempt to broaden the base of decision-making and to incorporate the concerns of stakeholders into resource management.
