The Unassuming Economist

From a paper by Roubyou Said and Ouakil Hicham:

“In this study, we aimed to assess the effectiveness of monetary policy in influencing housing prices in Morocco. Bayesian estimation over the period 2007Q2–2017Q2 of a dynamic stochastic general equilibrium model allowed us to reveal a significant impact of the increase in policy interest rates on the prices of residential goods. Indeed, the implementation of a restrictive monetary policy in Morocco will drive the prices of this type of asset downward. Despite this empirical finding, the historical decomposition of shocks impacting the inflation of residential property prices shows that interest rates explain only a small portion of the variations in housing prices in this country. Our results also indicate that an increase in the share of borrowers extends the time required for economic and financial variables to return to their equilibrium state. This is a sign of the potential dangers of fueling housing bubbles through credit booms.”

“The Russia-Ukraine invasion presents one of the most trending news in 2022. Economies having solid ties with Russia are exposed to the contagion effects of the crisis. The South African economy is strongly linked to Russia via international trade and the Brazil, Russia, India, China and South Africa (BRICS) alliance. This study investigates the impact of the Russia-Ukraine invasion on daily and monthly commodity prices in South Africa for the 2015-2023 period. The study applies descriptive statistics, dummy regression model and sub-period analysis to evaluate wheat prices, oil prices and inflation rate before and during the Russia-Ukraine invasion. The descriptive analysis and regression results indicate an increase in wheat prices, oil prices and inflation rates during the post-invasion period compared to the pre-invasion period. This implies a significant impact of the Russia-Ukraine invasion on these economic indicators in South Africa. Policy implications of the findings are highlighted in the concluding section.”

From a paper by Joan Crespo & Jesús Peiró-Palomino:

“This article studies the dynamics of innovation in the US Core-Based Statistical Areas over a long period (1860–2019), with the production of patents used as a proxy for innovation. The results show that innovation has always been highly concentrated, albeit with alternating periods of greater and lesser concentration. Despite the relative stability of the distribution of innovation, cities have experienced notable movements inside the distribution, which are the result of progressive long-run tendencies. Moreover, a remarkable change in the innovation landscape is found due to cities in the Northwest and Midwest gradually losing ground to cities in the South and the West. Finally, the technological specialization of cities changes rapidly, and the technological life cycle phase conditions cities’ mobility within the innovation distribution. Specialization in growing technologies helps cities to improve their relative position in the distribution, while the opposite is the case for cities that specialize in mature technologies.”

From a paper by Mohamed Ben Omar Ndiaye, Ebrima K Ceesay, and Yahaya M Moussa:

“In the theoretical literature, the relationship between primary producer commodity prices and economic change has been confirmed. Therefore, this paper examines sub-Saharan African countries’ experiences pertaining to commodity price variation. The main purpose of this article is to examine the impact of commodity price instability in sub-Saharan Africa. To do so, panel data models are used to solve the problems of unobserved variables. The results reveal that the current growth of commodity prices has a positive effect on the growth of the economy. However, the logs of the lags and logs of the leads of the commodity price have negative impacts on the growth of the economy. That means that commodity price variations will continue to harm the economies of sub-Saharan African countries.”

From a paper by Johnson Worlanyo Ahiadorme:

“The question of the implication of the macroeconomic policy environment for welfare may be an empirical one, and the answer may well differ amongst economies. In this paper, we evaluate the role of monetary policy toward inclusive growth. The evidence from a large sample of countries shows that in both the short and long terms, low inflation and stable economic growth are associated with lower income inequality, improved well-being of the poor and greater inclusion. Both short-term and long-run effects are statistically significant and show that monetary policy that aims at low inflation and stable economic growth is most likely to improve permanently growth inclusiveness and the conditions of the poor. However, in advanced economies where inflation rates are considerably lower, disinflation hurts the poor and equity, ignites greater unemployment cost, and worsens growth inclusiveness. In any case, price and output stability is necessary for greater growth inclusiveness. Thus, the twin objectives of macroeconomic stability and inclusive growth offer no trade-offs.”
