This study investigates the growth and welfare effects of monetary policy in a Schumpeterian economy featuring cash-in-advance (CIA) constraints and two engines of growth: innovation from R&D and human capital accumulation from endogenous fertility. Our theoretical analysis considers the cases of various CIA constraints. When the CIA constraint is only on consumption, higher inflation retards economic growth by weakening human capital accumulation. When the CIA constraint is only on R&D, higher inflation would generate a negative or U-shaped effect on economic growth, depending on the interplay between inflationary effects on innovation and human capital accumulation. When the CIA constraint is only on manufacturing, the growth effect of inflation could be positive (negative) if the positive growth effect from technological progress dominates (is dominated by) the negative effect from human capital accumulation. Our quantitative analysis finds a generally negative inflation-growth relationship in the calibrated economy. Moreover, the welfare effect of inflation is also negative, implying that the Friedman rule is optimal.

Empirical evidence on the relationship between aid and economic growth is mixed and inconclusive. This paper proposes a theory to explain these contradictory findings. We build an endogenous growth model with a productive public good and homogeneous agents who allocate their time to both work and the appropriation of public resources. Aid increases public resources, raising the provision of the productive public good, but promotes rent-seeking. As recent empirical evidence suggests, a hump-shaped relationship between aid and growth emerges: too much aid is counterproductive for growth, particularly when institutions are weak. Aid transmits growth from the donor to the recipient country but harms income convergence and even prevents convergence among ex-ante identical countries when aid exceeds a certain threshold. Institutional improvements raise such a threshold. Thus, countries with lower income and lower institutional quality should receive less aid, unless an institutional reform is taken as a previous step to receive that aid.

Developing economies often borrow abroad in foreign currency, which exposes them to the problem of “original sin.” Although the literature on the issue is relatively extensive, there is limited discussion about the role of fiscal frameworks, such as fiscal rules, in addressing original sin. Using a panel of 59 developing countries from 1990-2020 and applying the entropy balancing method, this study reveals that fiscal rules play a crucial role in reducing government debt in foreign currency, and that the effects are statistically and economically significant and robust. Furthermore, we find that the effectiveness of fiscal rules in curbing original sin is enhanced by factors such as the strengthening of the rule itself, improved fiscal discipline before the reform’s adoption, financial development, financial openness, exchange rate flexibility, the level of economic development, and sound institutions. Finally, transmission channels analysis reveals that the effect of fiscal rules on original sin is driven by fiscal and monetary policy credibility.

A Constant Elasticity of Substitution (CES) aggregator of domestic and foreign goods is assumed in virtually any model of international macroeconomics with multiple traded goods. If baskets of traded goods are allocated optimally across countries, the CES aggregator links trade flows to exchange rate dynamics implying a condition for optimal allocation of individual traded goods across countries. The condition holds irrespectively of assumptions about preferences or endowment processes. This paper analyzes optimal allocation of traded goods empirically for 9 OECD countries and finds that it is mostly rejected by data. The finding casts doubts on the ability of international macroeconomic models to jointly explain dynamics of consumption and exchange rates.

In this paper, we study the relationship between economic uncertainty, households’ credit situations, and educational outcomes. Using the System Generalized Methods of Moments (SYS-GMM) on educational and economic data from the World Bank and IMF, we find that economic uncertainty and households’ access to credit have positive impacts on higher education. Further analyses suggest that economic uncertainty and households’ access to credit have heterogeneous effects on educational outcomes at the tertiary level, by gender and development status. Specifically, we find that economic uncertainties expand enrollments in developed countries and contract them in developing economies. In addition, access to credit has a more pronounced positive impact on educational outcomes in developing nations compared to developed ones. Furthermore, our analysis indicates that household credit coupled with economic uncertainty decreases women’s educational outcomes in higher education, posing a serious threat to gender equality in higher education. Lastly, we find that monetary policy appears to play a role in these results. These findings remain robust to alternative proxies of economic uncertainty and approach such as the Instrumental Variable (IV) regression method, which uses a political database on government changes and ideological gaps between cabinets as instruments. In general, the findings emphasize the enduring influence of economic uncertainties, typically associated with business cycles, on long-term aspects such as education.

By constructing a two-country model with asymmetry in price-setting behavior between home and foreign intermediate goods firms, vertical production and trade, and endogenous entry of three types of final goods firms, this paper examines the effects of a home government spending shock. In particular, it focuses on the role of asymmetry in price-setting behavior between home and foreign intermediate goods firms. A home government spending shock is shown to result in the entry of multinational firms from both countries, an increase in the aggregate outputs of both countries, a deterioration in home welfare, and an improvement in foreign welfare. In addition, with an increase in the ratio of home and/or foreign intermediate goods firms setting their export prices in the local currency, the effects of this shock on the entry of home multinational firms, the increase in aggregate foreign output, the deterioration in home welfare and the improvement in foreign welfare are shown to be weakened, while the effects of this shock on the entry of foreign multinational firms and the increase in aggregate home output are intensified.

This study presents an analytical framework to investigate the use of reserve requirements as an indirect instrument to manage CBDC flows in an environment with significantly positive rates. This would complement two other possible instruments: hard limits, whose sole use may raise some concerns, and CBDC remuneration, which in a positive rate environment is not considered a viable option. As in the case of emerging market economies with a flexible exchange rate, in a CBDC framework reserve requirements could be used as a countercyclical tool for macroeconomic stabilization to influence bank lending/funding conditions consistently with the monetary policy stance. In an ample-reserves regime, the effectiveness of this tool would be favored by retaining the interest rate on required reserves and the interest rate on excess reserves (the real key policy rate) as two distinct policy instruments, with the former remaining stable below the latter.

This paper identifies supply and demand curves for bank reserves and a Divisia aggregate of monetary services within a structural vector autoregressive time-series model. Estimated over four sample periods spanning 1967 through 2020, the model illustrates how monetary policy actions can be interpreted with reference to their initial impact on bank reserves and the federal funds rate and their subsequent effects on Divisia money, nominal consumption spending, the aggregate nominal price level, and the unemployment rate. Model estimates attribute strong inflationary effects to monetary policy in the late 1960s and 1970s and also show that changes in the supply of reserves associated with the Fed's large-scale asset purchases since 2008 worked, as intended, to offset deflationary pressures and reduce unemployment. The model describes a much richer monetary policy process than one focused on interest rates alone.

This paper provides a new insight into the price puzzle using a new Keynesian (NK) model with household heterogeneity. To do this, we adopt a tractable heterogeneous-agent NK (THANK) model that nests the two-agent NK (TANK) and representative-agent NK models. We first demonstrate that when the share of liquidity-constrained (LC) consumers is high, the degree of inflation stabilization in the Taylor rule crucially affects whether the price puzzle occurs in the TANK model. Second, we show that regardless of the share of LC consumers, the price puzzle disappears in the THANK model with a discounted dynamic IS (DIS) curve. In contrast, for a compounded DIS curve, a higher share of LC consumers generates the price puzzle. Finally, we find that even in the case of a compounded DIS curve, reinforced interest rate smoothing can prevent the price puzzle.

Why are balance of payments crises, characterized by Sudden Stops of capital inflows, more frequent in emerging economies than advanced economies? This paper argues that differences in the composition of the financial account flows explain 30 percent of the gap in the probability of a crisis. I document that although advanced economies have, on average, zero net foreign direct investment (FDI), they have sufficient FDI outflows to act as buffer savings during financial distress. To quantify the effect of this FDI channel on the probability of a crisis, I propose a small open economy model with a loan-to-value collateral constraint and FDI vulnerable to government confiscation risk. The calibrated model suggests that if an emerging economy increases its capital-to-GDP ratio and eliminates government confiscation risk, it would reduce the probability of a Sudden Stop from 2.9 to 2.7 percent, while simultaneously increasing its debt-to-GDP ratio from 47 to 65 percent.
