We study a wide range of hybrid inflation–targeting (IT) and managed exchange rate regimes, analyzing their implications for inflation, output and the exchange rate. To this end, we develop an open economy new–Keynesian model featuring sterilized interventions as an additional central bank...

We study the role of the exchange rate regime, reserve accumulation, and sterilization policies in the macroeconomics of aid surges. Absent sterilization, a peg allows for almost full aid absorption—an increase in the current account deficit net of aid—delivering the same effects as those of...

We develop a model to study the macroeconomic effects of public investment surges in low-income countries, making explicit: (i) the investment-growth linkages; (ii) public external and domestic debt accumulation; (iii) the fiscal policy reactions necessary to ensure debt-sustainability; and (iv)...

We develop a semi-structural new-Keynesian open-economy model, with separate food and non-food inflation dynamics, for forecasting and monetary policy analysis in low-income countries and apply it to Kenya. We use the model to run several policy-relevant exercises. First, we filter international...

Natural resource revenues provide a valuable source to finance public investment in developing countries, which frequently face borrowing constraints and tax revenue mobilization problems. This paper develops a dynamic stochastic small open economy model to analyze the macroeconomic effects of...

Many low-income countries continue to describe their monetary policy framework in terms of targets on monetary aggregates. This contrasts with most modern discussions of monetary policy, and with most practice. We extend the new-Keynesian model to provide a role for “M†in the conduct...

We develop a model to analyze the macroeconomic effects of a scaling-up of aid and assess the implications of different policy responses. The model features key structural characteristics of low-income countries, including varying degrees of public investment efficiency and a learning-by-doing...

Natural resource revenues provide a valuable source to finance public investment in developing countries, which frequently face borrowing constraints and tax mobilization problems. This paper develops a dynamic stochastic model to analyze the macroeconomic effects of investing resource revenues,...

We develop a tractable open-economy new-Keynesian model with two sectors to analyze the short-term effects of aid-financed fiscal expansions. We distinguish between spending the aid, which is under the control of the fiscal authorities, and absorbing the aid-using the aid to finance a higher...

We develop a DSGE model with a banking sector to analyze the impact of the financial crisis on Zambia and the role of the monetary policy response. We view the crisis as a combination of three related shocks: a worsening in the terms of the trade, an increase in the country’s risk...
