Central Bank Governance and Reserve Portfolios Investment Policies: An Empirical Analysis (2024)

This paper examines the drivers of fluctuations in global inflation, defined as a common factor across monthly headline consumer price index (CPI) inflation in G7 countries, over the past half-century. It estimates a Factor-Augmented Vector Autoregression model where a wide range of shocks, including global demand, supply, oil price, and interest rate shocks, are identified through narrative sign restrictions motivated by the predictions of a simple dynamic general equilibrium model. The authors report three main results. First, oil price shocks followed by global demand shocks explained the lion’s share of variation in global inflation. Second, the contribution of global demand and oil price shocks increased over time, from 56 percent during 1970–1985 to 65 percent during 2001–2022, whereas the importance of global supply shocks declined. Since the pandemic, global demand and oil price shocks have accounted for most of the variation in global inflation. Finally, oil price shocks played a much smaller role in global core CPI inflation variation, for which global supply shocks were the main source of variation. These results are robust to various sensitivity exercises, including alternative definitions of global variables, different samples of countries, and additional narrative restrictions.

This study assesses the short-term impact of fiscal policy, and its individual elements, on poverty and inequality in Cambodia as of 2019. It applies the Commitment to Equity methodology to data from the Cambodia Socio-economic Survey of 2019/20 and fiscal administrative data from various government ministries, departments, and agencies for the assessment. The study presents among the first empirical evidence on the impact of taxes and social spending on households in Cambodia. The study finds that: (i) Cambodia’s 2019 fiscal system reduces inequality by 0.95 Gini index points, with the largest reduction in inequality created by in-kind transfers from spending on primary education; (ii) while Cambodia’s fiscal system reduces inequality, the degree of inequality reduction is small in international comparison; and (iii) low-income households pay more in indirect taxes than they receive in cash benefits in the short term to offset the burden. As a result, the number of poor and vulnerable individuals who, in the short term, experience net cash subtractions from their incomes is greater than the number of poor and vulnerable individuals who experience net additions. Fiscal policy can deliver more net benefits to poor and vulnerable households through expanding social assistance spending. Cambodia has embarked on this expansion during the coronavirus pandemic, bringing it closer in line with comparators.

Most developing economies rely on foreign capital to finance their infrastructure needs. These projects are usually structured as long-term (25–35 years) franchises that pay in local currency. If investors evaluate their returns in terms of foreign currency, exchange rate volatility introduces risk that may reduce the level of investment below what would be socially optimal. This paper proposes a mechanism with very general features that hedges exchange rate fluctuation by adjusting the concession period. Such mechanism does not imply additional costs to the government and could be offered as a zero-cost option to lenders and investors exposed to currency fluctuations. This general mechanism is illustrated with three alternative specifications and data from a 25-year highway franchise is used to simulate how they would play out in eight different countries that exhibit diverse exchange rate trajectories.

Inequality of opportunity leads to misallocation of human capital and can affect economies via its impact on individual economic decision making. This paper studies the impact of inequality of opportunity on investment, using a laboratory experiment. The experiment randomized inequality of opportunity, then subjects chose to invest in a risky asset or savings. The results suggest that inequality of opportunity impacts investment choices only for people who are penalized by their circ*mstances and only once they learn the impact of inequality of opportunity on their relative position in the income distribution. This disadvantaged group invests more often and invests higher shares of their earnings than the control and advantaged groups. The fact that both inequality of opportunity and knowledge of relative position need to be present for the impact on investment to materialize points to the importance of peer effects. More broadly, the paper highlights the relevance of social preferences for understanding the effects of inequality of opportunity on individual decision making.

Despite substantial progress in closing the gender gap, women’s labor force participation in the Middle East and North Africa remains one of the lowest globally, at a mere 18 percent. This paper investigates the effect of the introduction of unilateral divorce laws on women’s labor outcomes, using data from the Demographic and Health Survey program that spans decades and a quasi-experimental difference-in-differences design in three countries: Morocco, the Arab Republic of Egypt, and Jordan. The results highlight that no-fault divorce legislation was associated with a modest increase in mothers’ labor outcomes, measured by current employment, a few years after the reform. These findings are likely induced by a power shift and anticipatory effects that drive women into the labor force. However, when a longer time window is considered, 10 or more years after the reform, the study documents a negative effect of the reform on women’s labor outcomes in Morocco, and a positive effect in the Arab Republic of Egypt and Jordan. These differences can be attributed to a set of countervailing effects, including social norms, labor market dynamics, and evolution of the legislation, that make the derived utility from marriage, in some cases, more attractive than that derived from employment, and vice versa. These findings partially confirm results from previous research on the relationship between no-fault divorce and women’s agency and empowerment in the Middle East and North Africa region, but, at the same time, contrast with prominent perspectives on legislation that aims at reducing gender-based discrimination. Instead, they show that there might be undesired effects of legislation and provide a policy relevant discussion on that basis.
