The rapid increase in cross-border trade promises economic prosperity, especially for countries with good soft and hard infrastructures and macroeconomic conditions. This has spurred a strand of literature examining how these factors enhance or hinder a country’s effective participation in cross-border trade or its ability to gain the economic prosperity associated with cross-border trade. This dissertation contributes to this literature by focusing on four important threads that have gained traction in recent times, including intellectual property rights, export quality, capital controls, and foreign intermediate inputs. Along this line, the first substantive chapter of the essay examines how capital controls affect participation in cross-border trade. Results from the analysis show that capital controls adversely affect exports by increasing the cost of external capital. The second substantive chapter examines the impact of imported intermediate inputs on exported variety, further examining the role of absorptive capacity. The results show a significant positive effect of imported intermediate inputs on exported variety irrespective of whether it is sourced from developed or developing countries. However, the exported variety effects of imported intermediate inputs from developed countries depend on absorptive capacity. The third substantive chapter examines the effect of patent enforcement on the quality of exported products. The results show that effective patent enforcement increases the quality of exported products, with the effect being higher in R&D-intensive industries. Overall, the findings of the thesis imply that imported intermediate inputs, national policies, and institutions matter for cross-border trade, but sector and country characteristics influence the nature of their relationships. The dissertation highlights more specific policy options based on the findings.

Avenyo, Elvis & Gideon Ndubuisi, 2020, Coping During COVID-19: Family Businesses and Social Assistance in Nigeria, The COVID-19 pandemic and the consequent Government-imposed restrictions have altered the way of life around the globe. Using the newly “Nigeria Baseline COVID-19 National Longitudinal Phone Survey 2020”, this paper contributes to the nascent literature on the Economics of COVID-19 by examining the impact of changes in income and social assistance due to the pandemic on the coping strategies of family business owners. We find that family business owners who experienced a reduction in income and those that received social assistance due to the pandemic are likely to increase their coping level. We discuss the policy implications of these findings, More information

We also evaluate Nigeria’s country-wide response to Covid-19, while drawing inference from its past success on EVD to underpin factors that may have impeded the country’s from mimicking its successful erstwhile country-wide response in the fight against EVD. We complement this analysis with recent surveys for Nigeria to assess the spatial disparities in terms of vulnerability and shocks to Covid-19 and explore the spatial distribution of government and non-government assistance across the different regions
