Fiscal and Monetary Policies Interactions in Nigeria and South Africa: Dynamic Stochastic General Equilibrium Approach
Authors: Sanusi Kazeem Abimbola , Dickason-Koekemoer Zandri
Published: September 2023

The interaction between fiscal and monetary policies in achieving macroeconomic goals has been a subject of debate, particularly on whether they complement or substitute each other. This issue arises when both policy authorities are independent of each other. This study aims to revisit the interaction of fiscal and monetary policies in Nigeria and South Africa using a dynamic stochastic general equilibrium model (DSGE) and calibration technique. The model consists of 20 equations that illustrate the behaviour of endogenous variables. The parameters are obtained from relevant DSGE literature and economic intuitions about the two economies. The findings reveal that fiscal and monetary policy variables interact in both economies. Inflation responds to fiscal policy shocks such as government spending, revenue and borrowing shocks. Monetary authorities’ decisions such as interest rates and inflation also affect fiscal policy variables. However, the performance of monetary and fiscal policy variables is better in South Africa than in Nigeria. The study recommends closer coordination between the monetary and fiscal authorities in both economies to resolve policy design and implementation issues. Government monitoring and assessment units should also be strengthened to track the implementation and delivery of policies decided upon at coordination meetings.

Liver cancer has become a common cancer in Viet Nam and in the world. The in vitro study of the cytotoxicity on hepatocellular carcinoma cell line HepG2 is important for testing for active substances that are actually useful in treating liver cancer. In this study, based on literature and folk herbal knowledge in the use of Vietnamese medicinal herbs to treat cancer and liver diseases, we have evaluated cytotoxicity against HepG2, antioxidant capicity, total flavonoid and phenol content of methanol extracts from Luvunga scandens leaves (RLD1), Hyptis suaveolens (L.) roots (RLD9), Solanum torvum (Sw.) leaves (RLD10) and Zingiber zerumbet (L.) rhizomes (RLD7R). As a result, at 100 mg/L concentration of the extracts, RLD1 and RLD9 demonstrated the highest cytotoxicity with cell survival rate less than 27%. While RLD1 sample showed weak antioxidant capacity (IC50 = 426.275 0.005 mg/L), RLD9 possessed the stronger antioxidant activity (IC50 = 24.320 0.031 mg/L) as well as the highest total phenol content (97.441.46 mg GAE/g extract). Although RLD7R sample did not show any cytotoxic activity against HepG2 cells, it exhibited a strong antioxidant potential (IC50 = 21.326 0.083 mg/L), associated with the highest total flavonoid content (63.13 14.30 mg QE/g extract). This study has demonstrated that Luvunga scandens leaves and Hyptis suaveolens roots have potential in liver cancer treatment.

Aims Programmed cell death protein-1 (PD-1) is a membrane receptor expressed on the surface of T and B lymphocytes, monocytes, natural killers, and dendritic cells. In cancer, the PD-1/PD-L1 system prevents the proliferation of T lymphocytes and causes the release of cytokines and cytotoxicity, which leads to the apoptosis of tumor-specific T cells, thereby preventing the immune response to cancer cells. Methods & Materials In this study, the extracellular part of the humanized PD-1 protein was cloned and expressed, and the protein was injected as an antigen into a camel (Camelus dromedarius) to obtain a camel polyclonal antibody against PD-1 protein. Findings The obtained results indicate the proper expression of the protein in the prokaryotic system. Also, using various tests, such as ELISA and western blot, it was confirmed that the polyclonal antibody obtained from camel can identify PD-1 protein. Conclusion This study showed that because of the advantages, such as the ability to bind multiple epitopes, camel polyclonal antibodies can be used in antibody-based research for effective and strong molecular applications to detect PD-1 receptors.

Background: The natural origin of medicinal plants does not guarantee their safety, as there are no sufficient studies on the safety, efficacy, and toxicity to support their benefit claims. Objectives: This study aimed at investigating the oral acute toxicity of Adansonia digitata L. (A. digitata) fruit shell extract in mice. Methods: The maceration method was employed for the extraction of the A. digitata fruit shell using methanol. The extract was then screened for its phytochemical constituents both qualitatively and quantitatively. Lorke’s method was followed for the toxicity study, and the mice were observed for clinical signs of toxicity and mortality. Further, serum was analyzed for liver and kidney function biomarkers besides the histology of the liver, kidney, and cerebellum. Results: No single death was recorded and no sign of toxicity persisted for more than 2 hours post-administration to the extracts up to 5000 mg/kg. Therefore, the - of A. digitata fruit shell is above 5000 mg/kg. Additionally, no changes were observed in the weights as well as the relative organ weight of the mice. Further, no statistically significant changes were seen in their liver and kidney function biomarkers, besides the relatively intact histological appearance of their liver, kidney, and cerebellum. Conclusion: The oral acute toxicity of methanol extract of A. digitata fruit shell is above 5000 mg/kg; hence, it is relatively safe to use it for medicinal purposes. However, a longer study duration is recommended to evaluate its toxic effects on fertility, teratogenicity, and carcinogenic potentials.

Introduction: The growth of the divorce rate is considered as one of the severe harms of the change in the family institution, which brings with it the expansion of numerous social problems. The status of the economic factor is an influencing factor in divorce because economic disturbances cause quarrels and conflicts between the spouses, other effective factors are social and culture status, etc. There is a parallel relationship between the trends of macroeconomic developments in Iran and the trend of divorce. On the one hand, the unfavorable situation of Iran’s macroeconomic variables and on the other hand, the significant increase in the number of divorces in Iran for the past few decades, make it important and necessary to examine the impact of macroeconomic indicators on divorce. Method: The two-stage least squares method has been used to investigate the effect of economic variables on the divorce process in Iran (1370-1400; 1991-2021). The estimation of the equations has been done in a systematic way. This issue has been analyzed with the help of simultaneity bias and diagonality test. From identification problem over specified equations are confirmed. Findings: The results show that the effect of unemployment and inflation on divorce is likely to be significant, their coefficients are equal to 0.70 and 0.14. There is a direct relationship between women’s participation in the market and the divorce rate; its coefficient is 0.74. Also, there is a simultaneous relationship between the average age of women at first marriage, this variable, and the divorce rate. Discussion: The economy is an influential factor in couples’ decision to get divorced. Therefore, to reduce its rate, the unfavorable situation of economic variables should be improved. The role of women’s participation rate in the labor market is significant, but it should be noted that part of it can be due to the previous context. That is, couples have decided to divorce, due to bad economic conditions, social disturbances, personal factors, etc., but women’s lack of independence has been an obstacle to divorce, with the woman’s employment, ultimately, divorce takes place.

Пшениця – одна з найважливіших сільськогосподарських культур у світі, виробництво якої є важливим для людства. Несприятливі умови навколишнього середовища негативно впливають на фізіологічні процеси росту і розвитку пшениці та призводять до зниження урожайності. Одним із найгостріших екологічних факторів є водний дефіцит, спричинений посухою. Рослини розвивають різні складні механізми стійкості та адаптації до водного дефіциту, включаючи фізіологічні реакції. Водний потенціал рослин підтримується на високому рівні за рахунок добре сформованої кореневої системи. Питання щодо вивчення посухостійкості зернових культур, є актуальними, оскільки вони орієнтовані на вивчення реакцій рослин на водний стрес та впровадження методів підвищення стійкості рослин до посухи. Одним з таких методів є застосування метаболічно активних речовин. У статті наведено порівняльну характеристику впливу метаболічно активних речовин та їх комбінацій на механізми формування потужної кореневої системи та зниженню водного потенціалу коренів проростків пшениці м’якої (Triticum aestivum L.) в умовах водного дефіциту, змодельованого за допомогою ПЕГ 6000. Встановлено, що попередня обробка насіння розчинами убіхінону – 10 та магній сульфату (MgSO4), комбінаціями: вітамін Е + метіонін + параоксибензойна кислота (ПОБК), вітамін Е + метіонін + параоксибензойна кислота (ПОБК) + магній сульфат (MgSO4) стимулювала розвиток кореневої системи на 16,9 %, 8,9 %, 14,2 % та 10,2 % відповідно, порівняно з насінням яке знаходилося в умовах водного дефіциту, змодельованого за допомогою ПЕГ 6000. За обробки насіння пшениці T. аestivum розчином вітаміну Е та комбінацією вітамін Е + метіонін + параоксибензойна кислота (ПОБК) + магній сульфат (MgSO4) посилюють водозатримуючу здатність коренів в умовах уповільненого надходження води. Обробка насіння метаболічно активними речовинами сприяє підвищенню посухостійкості пшениці м’якої та може бути використана як елементи технології вирощування зернових культур в умовах водного дефіциту.
УРОЖАЙНІСТЬ КУКУРУДЗИ НА ЗЕРНО ЗАЛЕЖНО ВІД ФОРМ І НОРМ ВНЕСЕННЯ АЗОТНИХ ДОБРИВ В УМОВАХ ПІВНІЧНОГО СХОДУ УКРАЇНИ

У статті наведено результати досліджень щодо вивчення впливу різних форм та норм внесення азотних добрив на урожайність зерна кукурудзи в умовах північного сходу України. Виявлено найкращі параметри використання мінеральних добрив в удобренні кукурудзи. Встановлено, що серед досліджуваних форм азотних добрив, найвищою ефективністю відзначився безводний аміак, який, в середньому за роки досліджень, забезпечував рівень урожайності 8,55–10,2 т/га залежно від норми внесення азоту. Дещо меншою ефективністю відзначився карбамід, збір зерна кукурудзи при внесенні якого становив 7,97–9,70 т/га. Найменш ефективною формою азотних добрив в умовах північного сходу України виявився КАС-32. Його застосування в якості джерела мінерального азоту забезпечило урожайність досліджуваної культури 7,40–9,15 т/га. Встановлено оптимальну норму внесення азотних добрив в умовах північного сходу України. При використанні безводного аміаку, карбаміду та КАС-32 найвищою зерновою продуктивністю відзначився варіант досліду, на якому було внесено N150 на фосфорно-калійному фоні Р60К60. Залежно від форми азотних добрив, з 1 га було отримано від 9,15 до 10,2 т зерна кукурудзи. Використання як нижчих 90 та 120 кг/га д.р., так і вищих 180 та 210 кг/га д.р. норм внесення азотних добрив забезпечило значно нижчу ефективність, порівняно із вищезазначеним варіантом. Доведено, що в умовах північного сходу України найефективнішим способом азотного удобрення кукурудзи є внесення безводного аміаку в нормі N150. Приріст урожаю порівняно із контрольним варіантом без добрив становить 4,81 т/га або 89,2 %. Встановлено, що в середньому на формування 1 т зерна кукурудзи витрачається 16,1 кг азоту при використанні безводного аміаку,16,8 кг при внесенні карбаміду та 18,1 кг при застосуванні КАС-32. В той же час, кожна внесена одиниця мінерального азоту у формі безводного аміаку забезпечує формування 67,5 кг зерна кукурудзи, карбаміду – 64,1 кг та КАС-32 – 59,3 кг.
