Fiscal Stimulus under Sovereign Risk

The excess procyclicality of fiscal policy is commonly viewed as a central malaise in emerging economies. We document that procyclicality is more pervasive in countries with higher sovereign risk and provide a model of optimal fiscal policy with nominal rigidities and endogenous sovereign default that can account for this empirical pattern. Financing a fiscal stimulus is costly for risky countries and can render countercyclical policies undesirable, even in the presence of large Keynesian stabilization gains. We also show that imposing austerity can backfire by exacerbating the exposure to ...

Pricing-to-market and optimal interest rate policy

I study optimal interest rate policy in a small open economy with consumer search in the product market. When there are search frictions, firms price-to-market, with implications for the design of monetary policy. Country-specific shocks generate deviations from the law of one price for traded goods which monetary policy acts to stabilize by influencing firm markups. However, stabilizing law of one price deviations results in greater fluctuations in output.

International Reserves and Rollover Risk

We study the optimal accumulation of international reserves in a quantitative model of sovereign default with long-term debt and a risk-free asset. Keeping higher levels of reserves provides a hedge against rollover risk, but this is costly because using reserves to pay down debt allows the government to reduce sovereign spreads. Our model, parameterized to mimic salient features of a typical emerging economy, can account for a significant fraction of the holdings of international reserves, and the larger accumulation of both debt and reserves in periods of low spreads and high income. We ...

Remittances and COVID-19: A Tale of Two Countries

Looking at the effects of the COVID-19 pandemic on workers’ remittances flowing from the United States, this article focuses on the experiences of two countries, El Salvador and Mexico, which account for approximately 30 percent of all immigrants currently residing in the United States. Following the second quarter’s economic lockdown, transfers to these countries experienced perplexing dynamics.Specifically, remittances to El Salvador witnessed a record 40 percent sudden drop, while Mexico recorded an unexpected 35 percent increase. We discuss some of the narratives proposed to explain ...

Monetary Policy in Small Open Economies: The Role of Exchange Rate Rules

Understanding the costs and benefits of alternative monetary policy rules is important for economic welfare. Within the context of a small open economy model and building on the work of Mihov and Santacreu (2013), the author analyzes the economic implications of two monetary policy rules. The first is a rule in which the central bank uses the nominal exchange rate as its policy instrument and adjusts the rate whenever there are changes in the economic environment. The second is a standard interest rate rule in which the central bank adjusts the short-term nominal interest rate to changes in ...

Missing Import Price Changes and Low Exchange Rate Pass-Through

A large body of empirical work has found that exchange rate movements have only modest effects on inflation. However, the response of an import price index to exchange rate movements may be underestimated because some import price changes are missed when constructing the index. We investigate downward biases that arise when items experiencing a price change are especially likely to exit or to enter the index. We show that, in theoretical pricing models, entry and exit have different implications for the timing and size of these biases. Using Bureau of Labor Statistics (BLS) microdata, we ...

Modeling Time-Variation Over the Business Cycle (1960-2017): An International Perspective

In this paper, I explore the changes in international business cycles with quarterly data for the eight largest advanced economies (U.S., U.K., Germany, France, Italy, Spain, Japan, and Canada) since the 1960s. Using a time-varying parameter model with stochastic volatility for real GDP growth and inflation allows their dynamics to change over time, approximating nonlinearities in the data that otherwise would not be adequately accounted for with linear models (Granger et al. (1991), Granger (2008)). With that empirical model, I document a period of declining macro volatility since the 1980s, ...

Optimal monetary policy in open economies revisited

This paper revisits optimal monetary policy in open economies, in particular, focusing on the noncooperative policy game under local currency pricing in a two-country dynamic stochastic general equilibrium model. We first derive the quadratic loss functions which noncooperative policy makers aim to minimize. Then, we show that noncooperative policy makers face extra trade-offs regarding stabilizing the real marginal costs induced by deviations from the law of one price under local currency pricing. As a result of the increased number of stabilizing objectives, welfare gains from cooperation ...

Capital Controls and the Global Financial Cycle

Capital flows into emerging markets are volatile and associated with risks. A common prescription is to impose counter-cyclical capital controls that tighten during economic booms to mitigate future sudden-stop dynamics, but it has been challenging to document such patterns in the data. Instead, we show that emerging markets tighten their capital controls in response to volatility in international financial markets and elevated risk aversion. We develop a model in which this behavior arises from a desire to manipulate the risk premium. When investors are more risk-averse or markets are ...

Closing Small and "Sufficiently" Large Open Economies with Different Asset Structures

There are two important dimensions that matter when we write down a model economy of a country that is open to international financial markets. The first one is its size, and the second one is its asset market structure. Small open economies are price takers so the analysis happens in partial equilibrium, while countries that are “sufficiently" large can affect international prices and the analysis happens in general equilibrium. The second important dimension is the asset market structure. If markets are complete there is full risk sharing, while if markets are incomplete there is not. In ...
