This paper aims to analyze the volatility transmission between an energy stock index and a financial stock index in emerging markets during recent high instability periods. The study considers the impact of both the period under analysis and the data frequency on the direction and intensity of the contagion, as well as the effect of the potential spillovers on the risk measures. These questions still lack definitive answers and have become more relevant in a context of financially unsettling events such as COVID-19 crises.

This study employs an extension of the dynamic conditional correlation (DCC) model that allows for the time-varying dependence relationship between the variables. This dependence is analyzed at daily, weekly and monthly basis using data from the Bloomberg platform on energy and stock market indices for emerging markets between 2001 and 2021.

The results for a sample spanning from 2001 to mid-2021 show bidirectional volatility transmission on a daily basis, whereas only evidence of volatility transmission from the financial to the energy exists for weekly and monthly frequencies. However, considering different subsamples of daily data, the authors only find volatility transmission from financial (energy) index to the energy (financial) during the Great Recession (COVID-19) as a consequence of the different source of the shock and transmission channels.

This study reveals that volatility transmission between energy and stocks in emerging markets has changed and presents a unidirectional pattern from energy to financial markets during the COVID-19 period in contrast to calm and the sub-prime crisis intervals. These results differ from previous studies, focused on global markets, that show bidirectional spillovers during this period.

Uncertainty is one of the principal features of public administration in Colombia. Therefore, presenting a clear and consistent analysis is difficult. This uncertainty exists alongside interesting efforts to modernize institutions. Among the challenges faced by public administration in Colombia, we find corruption, illegal bands of drug traffickers, and the lack of trust between critical actors involved in governance. The aim of this chapter is to share an analysis that illustrates the difficulties and contradictions faced by those working in the public sector.

“Colombia is a legal social state organized in the form of a unitary republic, decentralized, with the autonomy of its territorial units, democratic, participatory, and pluralistic, based on respect of human dignity, on the work and solidarity of the individuals who belong to it, and the predominance of the general interest” (National Constitution, 1^st Article).

This chapter explores how the capacity of different sectors of the government influences which topics are prioritized in the legislative agenda. We focus on the complex and challenging topic of agriculture and the environment in Brazil and analyze how it's framed in both the media and the legislature. Our analysis shows that, in normal circumstances, the governmental actors with the highest state capacity prevent threatening topics from entering the legislative agenda, biasing it toward the status quo. However, we find that the media can act as a tool for sectors with lower capacity to bring their priorities to the forefront and trigger a legislative response.

Although researchers have proposed a shift in digital divide studies toward a focus on Internet use and skills, it is still relevant to talk about access as autonomy of use, as some individuals in both developing and developed countries still face barriers and do not have the freedom to choose how to connect to the Internet.

We look at the relationship between autonomy of use and online interaction with government and the relationship between the latter and individuals’ perceptions of the government. Data for this study was collected in 10 cities in Colombia between August 29 and September 17 of 2012 and represented Colombia’s urban adult population.

Results showed that autonomy of use had a positive relationship with online interaction with government. This online activity was positively related with individuals’ trust in government and negatively with perceptions of government corruption.

Findings suggest that certain uses have a higher probability of emerging as individuals’ environments become saturated with a broad set of connectivity options. Redundant efforts to increase connectivity can be valuable in assisting internet users. Public policy projects focused only on one access alternative might not be as beneficial as those that facilitate more varied types of Internet use. Additionally, the results could be interpreted to mean that that those high-trust individuals who perceive the government as less corrupt, tend to interact online more with it because they are part of an elite which has benefited from the government in some way.

The purpose of this paper is to examine the adoption of e-banking in Colombia, including a comprehensive analysis of consumer trust in this type of transaction and of the impact of the current government policy to promote e-commerce.

An empirical investigation based on the UTAUT2 model collected data from throughout the country to develop 600 online questionnaires.

The proposed model was validated in that the factors hypothesised to build trust in the use of electronic banking were shown to be significant: trust, performance expectancy and effort expectancy had a positive impact on the use of financial websites in Colombia, while government support did not have a significant impact.

The study explains the antecedents to trust, as well as the government support variable, and concludes by producing a model that is highly successful in predicting financial customers’ online behaviour.

The results can help Colombia’s Government and private banks to further develop trust and other conditions necessary for e-banking.

Studies on the adoption of electronic banking provide users of these services solutions for their needs. Government policies to support the development of e-banking are not viewed favourably by Colombians.

This study is one of the first to present empirical findings on the acceptance of e-banking in Latin America; it further presents a model that integrates the most important variables needed for an analysis of the acceptance of e-banking.
