Neste artigo é desenvolvido um modelo de crescimento baseado no progresso tecnológico endógeno, em que o crescimento econômico é induzido por melhorias contínuas na qualidade de cada produto diferenciado. A inovação, "motor" do crescimento, tem como "combustível" essencial o capital humano. Partindo dos modelos de base de Grossman e Helpman (1991a, 1991b), mas considerando, diferentemente, um índice de consumo constituído por bens diferenciados e um bem homogêneo, o modelo proposto destaca a influência determinante da procura no crescimento econômico, aspecto negligenciado pela literatura do crescimento endógeno. Do esforço de modelização decorre que consumidores pouco sofisticados, com reduzida preferência por produtos diferenciados em termos de qualidade, geram, seguramente, incentivos insuficientes para a investigação, enquanto que consumidores mais sofisticados podem gerar excesso de incentivos. Assim, se a quota dos produtos diferenciados na procura estiver positivamente correlacionada com o nível de desenvolvimento do país, então países menos desenvolvidos tendem a apresentar taxas de inovação relativamente reduzidas, ao contrário de países mais desenvolvidos, em que essas taxas podem até ser (socialmente) demasiado elevadas.

The commercialization of research done by universities and research institutes is seen as a key element of entrepreneurship, justifying a better understanding of the entrepreneurial process within those institutions. Despite efforts in recent decades, there remains a widespread ignorance about who are the individuals with a greater vocation for research and marketing of knowledge. Focusing on a relatively unexplored context — the field of life sciences in a moderate innovator country, Portugal — this study adds new empirical evidence to the precedents of academic entrepreneurship. The results, based on 247 responses, evidence that entrepreneurship (including patent production, consultancy work and creation of start-up companies) is still very incipient. The econometric analysis of the "Index of entrepreneurial activity," shows that: (1) the phenomenon of academic entrepreneurship is within everyone's reach, but embraced by very few; and (2) academic entrepreneurship feeds on the exchange of knowledge and resources among universities and research institutes and their socio-economic environment. Thus, to increase academic entrepreneurship in life science in Portugal, the mechanisms to facilitate the interactions between universities and the business community must be strengthened, promoting the development of business clusters with the integration of the academic world, which will enable the transformation of knowledge into market products and services.

Abstract
This paper assesses Brazil's real convergence (1822–2019) through unit root tests and Markov Regime-Switching (MS) models in three different scenarios: towards (i) other six Latin American countries (LA6); (ii) Portugal; and (iii) the technological frontier country, the US. The extended unit root test results favour Brazil's very long-run real convergence towards LA6 and Portugal, but not the US. The estimated MS models, involving two different regimes, real convergence and real non-convergence/divergence, capture institutional quality's positive effect in promoting Brazil's real convergence.

Scientific publications tend to influence policymakers significantly. Despite the scientific and social importance of poverty today, the attention the top economic journals (American Economic Review; Econometrica; International Economic Review; Journal of Economic Theory; Journal of Political Economy; Quarterly Journal of Economics; Review of Economic Studies) pay to the matter is not clear, particularly in the so‐called "Blue Ribbon" journals (and Review of Economics and Statistics). On the basis of bibliometric techniques, we analyzed all 27,322 articles published in the "Blue Ribbon" journals from 1970 to 2018. This is the first study on the scientific attention paid to poverty by the most influential journals in the field of economics. Two main findings can be highlighted: (i) the scientific attention paid to poverty in the Blue Ribbon journals is relatively meager, but it has observed a positive trend, increasing from a modest 0.36 percent of the total articles published in the 1970s to 1.92 percent of total publications in the 2010s; and (ii) the relative weight of specific poverty subtopics has significantly changed over the last 50 years, shifting from a focus on defining and measuring poverty in the earlier decades to policy‐related issues in the most recent period (2000 onward).

The present study assesses the perceptions of female entrepreneurs in Tanzania regarding the access to bank loans and the difficulties experienced in the process of financing their businesses. Focusing on small-scale businesses, face-to-face interviews were conducted with 75 female entrepreneurs from the Dar es Salaam area. Resorting to double-hurdle estimation models, we conclude that: 1) women who perceive higher discrimination and/or inequality in accessing bank loans, but who also recognize that female entrepreneurs often lack relevant business skills, tend to apply more often for bank loans; 2) women running larger business, operating in the tailoring industry, face fewer difficulties; 3) although highly educated female entrepreneurs apply less for bank loans, formal education acts as a shield to the difficulties faced by women when applying to bank loans; 4) more autonomous and money seeking female entrepreneurs are less likely to report difficulties during the bank loan application process.

The onset of the global crisis has emphasised the persistence of substantial differences in development and social progress within the euro area. The specific case of countries located in the southern periphery region has come to the centre stage, due to the harsh economic conditions that all these countries have experienced in the recent past.In the aftermath of the American subprime credit bubble, these countries' high indebtedness raised doubts as to their ability to sustain public finances, with the financial crisis developing and gaining momentum due to the fragilities presented in the ec

Entrepreneurs are critical for countries' industrial dynamics and economic growth. Although there are several studies focusing on the attitudes, cognitions and traits of entrepreneurs, only a few have explored the link between entrepreneurship and the job features entrepreneurs most value in the work setting. Taking a longitudinal perspective, over two periods of time, 1990–1993 and 2008–2010, the present study resorted to the European Value Study dataset, encompassing 27 European countries and more than 100 thousand individuals. Based on logistic estimates, we found that, compared with non-entrepreneurs, entrepreneurs consider work more important than other life dimensions (except family). Moreover, some work values associated with entrepreneurship (e.g., use initiative, achieving something, responsible job, meeting abilities, have a say, and learning new skills) are indeed mentioned the most by entrepreneurs and emerged significantly related with entrepreneurial propensity. Finally, some work values (e.g., have a say) are associated with entrepreneurship propensity regardless of country's culture, whereas others (e.g., interesting job) are strongly influenced by culture.

Empirical studies are scarce on the usefulness of state trade missions as a way to promote the internationalization of firms. The results of applying an econometric model — involving 136 participations in twelve state trade missions that occurred between 2005 and 2008 — indicate that a company's size, foreign capital, export intensity, innovation intensity and experience in the market visited are relevant variables in an assessment of the results of state trade missions. Investment in the simple organization of trade state missions is not enough. It is necessary to select the most competent companies and to add more structured programmes to the organization of a mission in order to create and improve firms' competences.
