To understand the beef industry’s response to the COVID-19 pandemic, I proposed a three-sector model of the beef supply-chain and estimated it econometrically. Based on their definitions, it is found that panic, stay-at-home procedures, and expectations are not significant explanatory variables. However, there is strong evidence that COVID-19 spread in a set of counties with large meatpacking plants has the effect of increasing wholesale beef prices, while country-wide spread has the effect of reducing wholesale prices. The results further imply differences in competition across the market levels, with wholesalers responding as if they face less competition than retailers and farmers.
In South Africa’s apartheid regime a white minority controlled the black African majority from 1948 until 1994, creating income and wealth inequalities between the different races that linger today. This paper uses data from the 2008 and 2014 National Income Dynamics Survey (NIDS) to understand income inequalities within and between racial categories, to examine how different income sources contribute to overall income inequality, and to study how the interaction between race and poverty shapes the inequality between African households when decomposing into subgroups above and below the poverty line. For this study, I use Gini coefficients to measure inequality. My findings demonstrate that Africans have continually earned less than their white counterparts, with an increase in inequality in all racial groups except for Africans. The Gini coefficient for government income in both years is relatively low, suggesting that it serves as redistributive income. Finally, for African households, wage income is a big contributor to the overall inequality, while government income can be seen more clearly as a redistributive source of income. This has implications for future government policies designed to address inequality.
Despite 97% of scientists believing that climate change is occurring, a far smaller proportion of ordinary citizens agree with this statement and the proportion of those who do greatly diverge by political affiliation. This paper lays out a dynamic information updating model with adaptation choice as the final outcome, linking information perception, belief perception, and behavioral implementation. Furthermore, this paper examines how various behavioral and environmental factors affect the agent’s adaptation choices by means of such cognitive processes. This research has implications for further research on climate change preference formation and effective communication strategies, such as informative or normative nudges.
