This paper contributes to the research on the macroeconomic origins of conflict. Based on a sample of 133 low- and middle-income countries over a 30-year period, it analyses to what extent changes in a country’s commodity terms-of-trade (ToT) can explain an increase in the incidence and intensity of conflicts through their effect on aggregate income. While the evidence from previous studies on the link between macroeconomic conditions and conflict is rather inconclusive, we find a significant relationship. Our baseline model finds that a negative commodity ToT shock leads to an increase in the number of conflict events and fatalities. Moreover, the effect plays out over several years albeit with decreasing strength after the second year; and its magnitude is twice as large for Low-Income Countries and Fragile and Conflict-affected States when compared with the sample average. In addition, our results show that macroeconomic shocks are creating more violence in countries with higher inequality and in cases where fiscal policy faces relatively stronger constraints on financing a response to the initial shock to incomes. Our results are robust to a number of plausible variations in model specification. The paper’s results, in conjunction with previous studies that emphasize the economic cost of conflicts, suggest the presence of a fragility trap—a vicious cycle of worsening economic conditions and deteriorating conflicts. Effective policies and well-tailored external financial support could be expected to help countries address this challenge.
The use of cash for payments is not well measured. We view the value of cash withdrawn from ATMs, or as a share of all payments, as a more accurate and timely measure of cash use compared to the standard measure of currency in circulation, or as a ratio to GDP. These two measures are compared for 14 advanced and emerging market economies. When aggregated, the trend in cash use for payments is currently falling for half the world’s population. Such a measure can help inform policy decisions regarding CBDC and regulatory decisions concerning access to and use of cash.
Central bank digital currencies (CBDCs) promise many benefits but, if not well designed, they could have undesired consequences, including for monetary policy. Issuing an unremunerated CBDC or a wholesale CBDC does not change the objectives of monetary policy or the operational framework for monetary policy. CBDCs can, however, induce changes in the retail, wholesale and cross border payments that have negative spillover effects on monetary policy, through their effects on money velocity, bank deposit disintermediation, volatility of bank reserves, currency substitution, and capital flows. Countries most vulnerable are those with banking systems dominated by small retail deposits and demand deposits, low levels of digital payments and weak macro fundamentals. Proposed CBDC design features, such as caps on CBDC holdings and unremunerating the CBDC can moderate disintermediation risks, but they are not sufficient. Central banks will need to ensure that unintended macroeconomic risks are comprehensively identified and mitigated.
We use randomized controlled trials in the US, UK, and Brazil to examine the causal effect of public debt on household inflation expectations. We find that people underestimate public debt levels and increase inflation expectations when informed about the correct levels. The extent of the revisions is proportional to the size of the information surprise. Confidence in the central bank considerably reduces the sensitivity of inflation expectations to public debt. We also show that people associate high public debt with stagflationary effects and that the sensitivity of inflation expectations to public debt is considerably higher for women and low-income individuals.
We compile a novel database on average public and private sector wages and public-private wage differentials, which we use to analyze how average public-private wage differentials vary according to gender and skill level as well as over time. We further examine the dynamic relationship between public and private wage levels and the implications for inflation. On average, public-sector workers earn around 10 percent more relative to comparable private sector workers, with the premium being higher for women, low-skilled workers, and in developing countries. The average public sector wage premium varies counter-cyclically, increasing during economic downturns, and increases prior to elections. Both private sector wages and inflation respond positively to changes in public wages, albeit with significant heterogeneity in the effects across countries reflecting differences in labor market characteristics and prevailing macroeconomic conditions.
