Abstract
Most empirical research on the effects of the economic downturns has been a-spatial and overlooked the location choices of creative industries (CIs). The present study addresses an open debate on whether economic downturns have pushed a change in the relative importance of resilience-based versus traditional CIs location factors. Considering the location choices of 6332 CIs Portuguese start-ups in the period 2005-2012, we found that: (1) the crisis brought changes in the relative importance of location factors, enhancing traditional CI location factors such as technology and diminishing the relevance of resilience-based factors related to regions industrial specialisation; (2) resilience-based factors, such as industrial diversity, higher education, cultural and social networking and traditional CI factors, namely lower social inequality and life quality, were robust drivers for the emergence of new start-ups all over the period; and (3) although cultural policy significantly and positively support the emergence of new CIs start-ups in the crisis period, the austerity period reversed that role. Our results suggest that the sustainable development of regions implies encompassing public stimulus to the generation of a diversified, interdependent network of creative activities, able to enhance innovation through their own synergies and linkages with the rest of the economy.

Abstract
The issue of population ageing is no longer exclusively centred on developed countries. Empirical studies have proven that the rise in the proportion of the older age group has been already visible in the least developed countries (LDCs). The primary concern of population ageing in LDCs is that ageing is approaching LDCs even faster than approaching developing and developed countries. We found that despite the common factors such as human capital development, female participation in the labour market and economic growth, the annual growth rate of the ageing of LDCs highly depends on international aids (health care and development) and the rising number of emigrations over the working-age population. Our empirical results suggest that the existence of the ageing population in LDCs determine by the involvement of international bodies in supporting the welfare system of the country and the policy initiatives of developed countries in attracting migrant workers of LDCs to overcome the ageing problem in their countries.

Abstract
Purpose This study aims to understand why young people are interested in buying frugal innovations. Design/methodology/approach Data were collected with a survey administered to 534 university students enrolled in various fields of study (e.g. sciences, technology, economics and fine arts). Using the Tata Nano car as an example of frugal innovation, a model based on the unified theory of acceptance and use of technology was developed using partial least squares structural equation modeling. Findings The model's results reveal that effort expectancy, performance expectancy and facilitating conditions are critical factors that explain university students' intention to buy Tata Nano. Originality/value Although frugal innovations are often introduced first in developing countries, frugal innovations could be highly relevant to users in developed nations as these innovations can provide market opportunities in terms of cost-conscious, relatively low-income and sustainability-conscious consumers.

Abstract
Objective: We aim to answer four questions. First, with the increasing number of publications, is there a concentration in specific subjects, or on the contrary, a dispersion, amplifying the span of themes related to entrepreneurship? Second, is there a hierarchy of subjects, in the sense that some of them constitute the “core” of entrepreneurship? Third, are they connected with other established research areas? Finally, it is possible to identify papers that are influential, acting as hubs in the cluster’s formation? Method: We developed an original version of the computational procedure proposed by Shibata et al (2008), which allows us to understand the diversity of the different sub-areas of the topic investigated, reducing the need for specialist supervision. Originality/Relevance: We developed and applied a method to capture the formation and evolution of research areas in entrepreneurship literature, via direct citation networks, allowing us to understand the iteration between the different research sub-areas. Results: The dispersion is a feature of entrepreneurship as field research, with a hierarchy between research areas, indicating an emergent organization in the expansion processes. We concluded that research on entrepreneurship consists of specialization, that is, by application in niches. © 2022, Associacao Nacional de Estudos em Empreendedorismo e Gestao de Pequenas Empresas - ANEGEPE.

Abstract
The relevance of international research collaboration (IRC) in bolstering intellectual capital, in-creasing embeddedness in networks, and promoting innovation has been acknowledged by sci-entists and policymakers. However, large-scale studies involving different scientific domains and periods aimed at exploring the factors that influence IRC are missing, which could deepen our understanding of the factors affecting IRC. Based on a novel dataset of 193 countries over three periods, 1990-1999, 2000-2009 and 2010-2018, we have examined the impact of geographical, socioeconomic, political, cultural, intellectual, and excellence distances on the propensity to engage in IRC at the global level, by scientific domain and over time. In general, all the distances considered obstruct IRC, with geographical and cultural distance emerging as the barriers with the highest impact. Two exceptions are worthwhile noting: excel-lence distance fosters IRC in the Medical & Health Sciences (MHS) and intellectual distance fosters IRC in the Agricultural Sciences (AS). At the global level, the negative impact of socioeconomic, political, and intellectual distances on IRC has increased over time, whereas the negative impact of geographical and cultural dis-tances has decreased.

Abstract
ABSTRACT The reconstruction of the economic history of Brazil since independence from Portugal (1822) may lead to a new understanding of its economic growth. The deep-rooted idea that Brazil could have done better means there is a need to delve into each phase of its development. In this paper, we provide a very long-run perspective (1822-2019) of Brazil’s economic growth and process of real convergence. On the one hand, this review indicates that structural changes observed in the middle of the 20th century were crucial in promoting the country’s growth and real convergence with technologically advanced countries. On the other hand, poor institutional conditions and deficient human capital formation have emerged since colonial times as critical factors underlying Brazil’s inability to establish robust and sustainable economic growth.
