The Unassuming Economist

From a paper by Omang Ombolo Messono, Fabrice Assoumou Zambo, and Alexandre Turpin Iroume A. Bouebe:

“While many studies have highlighted the influence of the degree of central bank independence on economic and financial dynamics, less is known about its importance for economic vulnerability. The objective of this paper is to examine, for the first time, the effect of central bank independence on economic vulnerability in Africa. Based on the hypothesis that countries with more independent central banks are less vulnerable to external shocks, we estimate a dynamic panel model using the system generalised method of moments in a sample of 44 African countries between 1990 and 2017. Our results show that an independent central bank can significantly reduce the economic vulnerability of African countries by allowing monetary policy decisions to be made outside political influence, promoting financial stability, and strengthening the credibility of economic policy. These results remain robust to alternative measures of the main variables. Furthermore, the analysis of transmission mechanisms reveals that central bank independence has a negative effect on economic vulnerability in Africa through channels such as GDP growth, financial development, exchange rate misalignments and budget balance. We suggest that policymakers promote central bank independence in the development of public policies to address economic vulnerability in Africa.”

“This paper provides an overview of issues related to fiscal consolidation drawing on the literature; it distills some lessons from fiscal consolidation episodes using a new database covering 196 countries from 2000 to 2023. The paper discusses the motives, timing, design, and political economy of fiscal consolidation, as well as its macroeconomic and social impacts. We find that fiscal consolidation is often necessary and successful in restoring fiscal sustainability by stopping debt accumulation, but less successful in lowering debt levels; moreover, it can also entail significant costs and trade-offs in terms of growth, poverty, and inequality. Composition also matters, as expenditure-based consolidations tend to be more successful than revenue-based consolidations and less likely to cause a deterioration in poverty rates or inequality. However, revenue gains usually play an important role starting in the second year of consolidation. Overall, the paper suggests that successful fiscal consolidation requires careful consideration of the economic context, the composition of adjustment, complementary economic policies, and communication and credibility of the strategy. The best way to implement fiscal adjustment is to establish a consolidation strategy in normal/non-crisis times} to ensure that governments do not have to rely on abrupt, pro-cyclical adjustments that may exhaust all buffers in the aftermath of a shock.”

From a paper by Munseob Lee, Claudia Macaluso, and Felipe Schwartzman:

“Our paper addresses the heterogeneous effects of monetary policy on households of different races. The cyclical volatility of real income differs significantly for households of different races and income levels, reflecting differential exposure to fluctuations in employment and consumer prices. All Black households are disproportionately affected by employment fluctuations, whereas price volatility is only particularly pronounced for Black households with income above the national median. The latter face 40 percent higher price volatility than both poorer households of the same race and white households of similar income. To evaluate the effects of policy, we propose a New Keynesian framework with heterogeneous exposure to employment and price volatility. We find that an accommodative monetary stance generates asymmetric outcomes within race groups. Low-income households experience unemployment stabilization benefits, while high income ones incur real income volatility costs. Differences are especially large among Black households. Reducing the volatility of unemployment by 1 percentage point engenders a 1.17 percentage point reduction in overall income volatility for poorer Black households, but an increase of 0.6 percentage points in income volatility for richer Black households.”

From a paper by Won Joong Kim, Juyoung Ko, Won Soon Kwon, and Chunyan Piao:

“Different crises, such as the GFC, COVID-19 pandemic, and RU-UA war, lead to the common economic consequences: fluctuations in global inflation. In a globalized world, global inflation matters because it also affects the national economy. Although the literature provides determinants of inflation at national and regional levels, no studies have measured global inflation and analyzed its sources of fluctuations during the GFC, COVID-19, and RU-UA war periods. To fill this void, we measure monthly global inflation and estimate its dynamics using a time-varying parameter structural vector autoregression model with stochastic volatility. The results from global data show that global inflation during crisis periods is greatly affected by the monetary and the oil price shocks. Finally, the application to the EMU member countries implies that high EMU inflation rates in recent years were dominantly caused by excessive expansionary monetary policy in the EMU system.”
