Most empirical papers on threshold effects between debt and growth focus on developed countries or a mix of developing and developed economies, often using public debt. Evidence for developing economies is inconclusive, as is the analysis of other threshold effects such as those probably caused by the level of relative development or the repayment capacity. The objective of this study was to examine threshold effects for developing economies, including external and total debt, and identify them in the debt-growth relation considering three determinants: debt itself, initial real Gross Domestic Product (GDP) per capita and debt to exports ratio.

We used a panel threshold regression model (PTRM) and a dynamic panel threshold model (DPTM) for a sample of 47 developing countries from 1970 to 2019.

We found (1) no evidence of threshold effects applying total debt as a threshold variable; (2) one critical value for external debt of 42.32% (using PTRM) and 67.11% (using DPTM), above which this factor is detrimental to growth; (3) two turning points for initial GDP as a threshold variable, where total and external debt positively affects growth at a very low initial GDP, it becomes nonsignificant between critical values, and it negatively influences growth above the second threshold; (4) one critical value for external debt to exports using PTRM and DPTM, below which external debt positively affects growth and negatively above it.

The outcome suggests that only poorer economies can leverage credits. The level of the threshold for the debt to exports ratio is higher than that found in previous literature, implying that the external restriction could be less relevant in recent periods. However, the threshold for the external debt-to-GDP ratio is lower compared to previous evidence.

This paper aims to provide information about the structure of collaborative work among Argentinian economics. The study provides specific applied research of social network analysis focus on this profession in this specific country.

The contribution opted for applying social network analysis tools to papers presented in a congress and published in its proceedings. The authors focus in detecting main actors, groups of co-authorship, professionals acting as bridges between groups and differences between genders.

The paper provides empirical insights about how co-authorship has evolved between Argentine economists. The authors find that structural properties of the network, main actors, both male and female, main universities or center that affiliates them, a gender gap that might be closing out.

The paper focuses on the network for the period 1964-2014 without a more detailed dynamic. It also does not explain main topics worked by the authors.

The work provides knowledge about how groups are created in Economics in Argentina, how cooperation has evolved and what has been the role of women in this development. It also shows how different departments and entities collaborate with diverse success in the creation of new knowledge in Economics in Argentina.

The paper works with data from a source of information non-previously studied and contributes in explaining a particular type of collaborative work in a profession in Argentina.

This paper enquires into general trends of China's International Development Cooperation over the past decade in Latin America and provides insights into the challenges with the Belt and Road Initiative.

This paper analyses quantitative data for Chinese Official Development Assistance (ODA) and Other Official Flows (OOF) for projects in Latin America based on recent data contributions including Bluhm et al. (2018) and Gallagher & Myers (2019).

Based on the data available, it can be concluded that the cooperation between China and Latin America has been increasing. For instance, the value of China's cooperation increased by 4.5% per year on average from 2000 to 2014. Moreover, China's economic and political motivations in the region indicate that the cooperative relationship has been changing from a South–South to a North–South framework. Two main factors are involved in this transition: the evolution of China from a developing country to a global emerging power and the implementation of the Belt and Road Initiative to strengthen political and economic ties with the governments of the region.

This investigation suggests that the increasing number of loans in the region and Beijing's growing interest in trade and natural resources are structural factors that guide the Chinese foreign policy.

There are few analyses of China's cooperation for development in Latin America that involve the evaluation of concessional and non-concessional loans for projects in the region in the last decade. This paper also analyses the challenges and opportunities that the implementation of the Belt and Road Initiative represents for the region.
