We show that explicitly modeling primary commodities in an otherwise totally standard incomplete markets open economy model can go a long way in explaining the Mussa puzzle and the Backus-Smith puzzle, two of the main puzzles in the international economics literature.

Financial inclusion is strikingly low in emerging economies. In only a few years, financial technologies (fintech) have led to a dramatic expansion in the number of non-traditional credit intermediaries, but the macroeconomic and credit-market implications of this rapid growth of fintech are not...

We study the role of multinationals (MNCs) in facilitating firm-level and aggregate structural transformation. Using a stylized model of multinational production and trade, we show that an inward multinational liberalization in the manufacturing sector raises employment in host country firms,...

This paper introduces a novel monetary policy framework where the exchange rate becomes the central instrument. Using Singapore as a case study, it explores the Monetary Authority's adoption of the exchange rate as the primary tool since 1981, diverging from conventional approaches centered on...

We study the welfare and macroeconomic implications of simple and implementable fiscal policy rules in commodity-dependent economies, where a large share of output, exports, and government revenues depend on exogenous and volatile commodity prices. Using a multi-sector New Keynesian model...

Singapore's unique monetary policy consists of a managed exchange rate framework that can be characterized as a Taylor-like reaction function with the nominal devaluation rate instead of the nominal interest rate as the main policy instrument. We build a small open economy New Keynesian model to...

This paper studies whether policymakers should wait to intervene until a financial crisis strikes or rather act in a preemptive manner. This question is examined in a relatively simple dynamic stochastic general equilibrium model in which crises are endogenous events induced by the presence of...

In the aftermath of the global financial crisis, a new policy paradigm has emerged in which old-fashioned policies such as capital controls and other government distortions have become part of the standard policy tool kit (so called macro- prudential policies). On the wave of this seemingly...

This paper analyzes the macroeconomic impact of China's 2009-2010 fiscal stimulus package by simulating a dynamic general equilibrium multi-country model of the world economy, showing that the effects on China's economic activity are sizeable: absent fiscal stimulus China's GDP would be 2.6 and...

This paper reviews the recent experience of a half-dozen Latin American inflation targeting (IT) nations. Repeated and large deviations from the standard IT framework are documented: exchange market interventions have been lasting and widespread; the real exchange rate has often become a target of...
