What quantitative lessons can we learn from models of endogenous technical change through innovative investments by firms for the impact of changes in the economic environment on the dynamics of aggregate productivity in the short, medium, and long run? We present a unifying model that nests several canonical models in the literature and characterize both their positive implications for the transitional dynamics of aggregate productivity and their welfare implications in terms of two sufficient statistics. We review the current state of measurement of these two sufficient statistics and discuss the range of positive and normative quantitative implications of our model for a wide array of counterfactual experiments, including the link between a decline in the entry rate of new firms and a slowdown in the growth of aggregate productivity. We conclude with a summary of the lessons learned from our analysis to help direct future research aimed at building models of endogenous productivity growth that are useful for quantitative analysis.

The factors required to achieve sustainable economic growth in a country are debated for decades, and empirical research in this regard continues to grow. Given the relevance of the topic and the absence of a comprehensive, systematic literature review, we used bibliometric techniques to examine and document several aspects in the empirical literature related to growth, from 1991 to 2020. Five main results are worth highlighting: (a) the share of empirical articles on economic growth show a clear upward trend; (b) among all the groups of countries considered, the emerging economies (EEs) have received the most scientific attention; (c) the economic growth processes of the Latin American and Caribbean EEs have observed negligible scientific attention; (d) the very long-run studies comprise a residual share among the empirical literature on growth; (e) the extant empirical studies on economic growth have addressed mainly the impact of “macroeconomic conditions.” Our findings suggest there is a need to redirect the empirical growth agenda, so as to encourage more scientific attention devoted to the analysis of key determinants of economic growth in the very long run. There should also be increased scrutiny of the processes of economic growth in Latin American and Caribbean EEs

Introduction. Today, almost the only industry in the country that Ukraine can really be proud of and which is considered one of the most technologically advanced in the world is the development of card technologies, payment technologies and card infrastructure. The purpose of the article is to analyze the current state of electronic payment systems in Ukraine and highlight development trends. Results. The modern fintech directions in Ukraine are analyzed and examples of the impact of COVID-19 on the market of electronic payment systems for the last period are given. A number of trends are highlighted for further research in the field of electronic payment systems, which are now quite promising. Perspectives. Given the significant increase in non-cash payments, the problem of developing financial technologies and spreading awareness among the population has become especially urgent. It is necessary to improve not only the financial technologies themselves, but also the ways of providing them to clients and promoting modern financial technologies. Electronic payment systems can still be considered one of the most promising areas for future research.

Arthritis is ranked among the top causes of disability in the United States and worldwide. Despite recent improvements in medications and medical treatment, there is no known cure for arthritis. Providing evidence-based psychoeducation and counseling services to people with arthritis lessens the impact of pain-related symptoms and disability on the individual and society. The purpose of this chapter is to provide an overview of the most common arthritic conditions, co-occurring physical conditions, and psychosocial factors associated with arthritis. Barriers to self-management and existing self-management programs are also discussed along with the current state of scientific evidence. The chapter concludes with some questions for future research.

This chapter examines the challenge of ending extreme poverty and attaining the Millennium Development Goals (MDGs) in fragile and conflict-affected countries by 2030. It first describes the background context in which fragility and conflict exist before discussing the current state of lessons learned as well as policy agreement and divergence regarding international approaches to peace and security. It then considers the centrality of institutions both as constraints and as foundations to development. It also offers suggestions on what key elements are needed in laying institutional foundations for development in countries emerging from conflict, and how responsibilities for implementing the goals might be assigned in practice. The chapter concludes with an assessment of the impact of the MDGs in fragile and conflict-affected settings, along with the implications of current understandings of conflict and fragility for the objectives of the Post-2015 Development Agenda.

Multi-cohort management that creates or maintains an uneven structure within forest stands has been widely advocated as a means to attenuate the impact of forest harvesting. An experimental network was put in place in black spruce forests of northwestern Québec to test this assertion. Here we synthesize the biodiversity results in two main lessons: (1) at least 40% to 60% retention of pre-harvest basal area was required to maintain pre-harvest conditions for most species groups; (2) partial harvests showed the potential to be efficient deadwood delivery systems. In addition to these two main general conclusions, we emphasise that future research should examine whether partial harvest may be able to advance forest succession.

This essay sketches the current state of fieldwork-based studies of Christianity in China, focusing on monographs published from 2008 to 2018. It discusses strengths and gaps in research paradigms (religious economy or market theory; rational-actor bargaining; institutional theory; religious ecology), levels of analysis (macro- or national level; meso- or regional level; micro- or congregational level), and modes of interaction (resistance-domination; negotiation; cooperation) in an effort to point out areas rich for future research: the impact of theologies and denominations, the existence of regional models of Christianity, and the study of money, real estate, social service, syncretism, and religious decline.

In the global economy, tourism is one of the most noticeable and growing sectors. Thissector plays an important role in boosting a nation’s economy. An increase in tourism flow canbring positive economic outcomes to the nations, especially in gross domestic product (GDP) andemployment opportunities. In South Asian countries, the tourism industry is an engine ofeconomic development and GDP growth. This study investigates the impact of tourism onPakistan’s economic growth and employment. The period under study was from 1990 to 2015. Tocheck whether the variables under study were stationary, augmented Dickey–Fuller andPhillips–Perron unit root tests were applied. A regression technique and Johansen cointegrationapproach were employed for the analysis of data. The key finding of this study shows that there isa positive and significant impact of tourism on Pakistan’s economic growth as well as employmentsector and there is also a long‐run relationship among the variables under study. This studysuggests that legislators should focus on the policies with special emphasis on the promotion oftourism due to its great potential throughout the country. Policy implications of this recent studyand future research suggestions are also mentioned.

This paper seeks to explore the aspects of being made homeless or Internally Displaced person (IDP) and how the team attempted to assess this. The team of 10 psychological researchers and statisticians spent a day at 5 camps in 4 locations within Kegalle, Sri Lanka. The languages within the team are Tamil, English and Sinhalese. The aim to find out if depression, anxiety and trauma symptoms are evident within child, adolescents and adults categories, 3 months after the landslide triggered by the storm Roanu May 2016. The participants volunteered to be interviewed using self report measures. The psychological researchers did have undergraduate and post graduate degrees in psychology. Whilst the project lead had clinical experience, the researchers did not and so this was their first field trip. The research was granted ethical clearance by the ethics board at CIRP – Colombo. Unfortunately, due to low numbers, significance is problematic and so this paper addresses the experience and lessons learned by implication for professional growth and future research with IDP. But the impact upon men’s health becomes clear as the team discovers the psychosocial aspects of being homeless.

IntroductionGiven the reach and influence of social media, the National Children’s Study Vanguard Study evaluated the feasibility, acceptability, and cost of using social media to support participant retention.MethodsWe describe a social media experiment designed to assess the impact of social media on participant retention, discuss several key considerations for integrating social media into longitudinal research, and review factors that may influence engagement in research-related social media.ResultsUser participation varied but was most active when at launch. During the short life of the private online community, a total of 39 participants joined. General enthusiasm about the prospect of the online community was indicated. There were many lessons learned throughout the process in areas such as privacy, security, and Institutional Review Board clearance. These are described in detail.ConclusionsThe opportunity to engage participants in longitudinal research using online social networks is enticing; however, more research is needed to consider the feasibility of their use in an ongoing manner. Recommendations are presented for future research seeking to use social media to improve retention in longitudinal research.
