Emerging Market Business Cycles: The Cycle is the Trend

Emerging market business cycles exhibit strongly countercyclical current accounts, consumption volatility that exceeds income volatility, and “sudden stops” in capital inflows. These features contrast with developed small open economies. Nevertheless, we show that a standard model characterizes both types of markets. Motivated by the frequent policy regime switches observed in emerging markets, our premise is that these economies are subject to substantial volatility in trend growth. Our methodology exploits the information in consumption and net exports to identify the persistence of productivity. We find that shocks to trend growth—rather than transitory fluctuations around a stable trend—are the primary source of fluctuations in emerging markets. The key features of emerging market business cycles are then shown to be consistent with this underlying income process in an otherwise standard equilibrium model.

International Prices and Exchange Rates

We survey the recent empirical and theoretical developments in the literature on the relation between prices and exchange rates. After updating some of the major findings in the empirical literature, we present a simple framework to interpret this evidence. We review theoretical models that generate insensitivity of prices to exchange rate changes through variable markups, both under flexible prices and nominal rigidities, first in partial equilibrium and then in general equilibrium.

Fire-Sale Foreign Direct Investment and Liquidity Crises

In placing capital market imperfections at the center of emerging market crises, the theoretical literature has associated a liquidity crisis with low foreign investment and the exit of investors from the crisis economy. However, a liquidity crisis is equally consistent with an inflow of foreign capital in the form of mergers and acquisitions (M&A). To support this hypothesis, we use a firm-level data set to show that foreign acquisitions increased by 91 in East Asia between 1996 and 1998, while intranational merger activity declined. Firm liquidity plays a significant and sizable role in explaining both the increase in foreign acquisitions and the decline in the price of acquisitions during the crisis. This contrasts with the role of liquidity in noncrisis years and in noncrisis economies in the region. This effect is also most prominent in the tradable sector. Quantitatively, the observed decline in liquidity can explain 25 of the increase in foreign acquisition activity in the tradable sectors. The nature of M&A activity supports liquidity-based explanations of the East Asian crisis and provides an explanation for the puzzling stability of FDI inflows during the crises.

Fire-Sale FDI and Liquidity Crises

In placing capital market imperfections at the center of emerging market crises, the theoretical literature has associated a liquidity crisis with low foreign investment and the exit of investors from the crisis economy. However, a liquidity crisis is equally consistent with an inflow of foreign capital in the form of mergers and acquisitions (M&A). To support this hypothesis, we use a firm-level dataset to show that foreign acquisitions increased by 88% in East Asia between 1996 and 1998, while intra-national merger activity declined. Firm liquidity plays a significant and sizeable role in explaining both the increase in foreign acquisitions and the decline in the price of acquisitions during the crisis. This effect is most prominent in the tradable sectors and represents a significant departure from the pattern of M&A observed both before and after the crisis. Quantitatively, the observed decline in liquidity can explain nearly 30% of the increase in foreign acquisition activity in the tradable sectors. We argue that the nature of M&A activity during the crisis contradicts productivity-based explanations of the East Asian crisis.

In Search of Real Rigidities

The closed and open economy literatures both work on evaluating the role of real rigidities, but in parallel. This paper brings the two literatures together. We use international price data and exchange rate shocks to evaluate the importance of real rigidities in price setting. We show that, consistent with the presence of real rigidities, the response of reset-price inflation to exchange rate shocks exhibits significant persistence. Individual import prices, conditional on changing, respond to exchange rate shocks prior to the last price change. At the same time, aggregate reset-price inflation for imports, like that for consumer prices, exhibits little persistence. Competitor prices affect firm pricing, and exchange rate pass-through into import prices is greater in response to trade-weighted, as opposed to bilateral, exchange rate shocks. We quantitatively evaluate sticky-price models (Calvo and menu cost) with variable markups at the wholesale level and constant markups at the retail level, consistent with empirical evidence. Variable markups alone generate price sluggishness at the aggregate level, while they fall short of matching price persistence at the micro level. Finally, variable markups magnify the size of the contract multiplier, but their absolute effects are modest unless they are coupled with exogenous sources of persistence.

Estimating the Border Effect: Some New Evidence

To what extent do national borders and national currencies impose costs that segment markets across countries? To answer this question the authors use a dataset with product-level retail prices and wholesale costs for a large grocery chain with stores in the United States and Canada. They develop a model of pricing by location and employ a regression discontinuity approach to estimate and interpret the border effect. They report three main facts: One, the median absolute retail price and wholesale cost discontinuities between adjacent stores on either side of the U.S.-Canadian border are as high as 21 percent. In contrast, within-country border discontinuity is close to 0 percent. Two, the variation in the retail price gap at the border is almost entirely driven by variation in wholesale costs, not by variation in markups. Three, the border gaps in prices and costs co-move almost one-to-one with changes in the U.S.-Canadian nominal exchange rate. They show these facts suggest that the price gaps they estimate provide only a lower bound on border costs.

Efficient expropriation: sustainable fiscal policy in a small open economy

We study a small open economy characterized by two empirically important frictions— incomplete financial markets and an inability of the government to commit to policy. We characterize the best sustainable fiscal policy and show that it can amplify and prolong shocks to output. In particular, even when the government is completely benevolent, the government’s credibility not to expropriate capital varies endogenously with the state of the economy and may be “scarcest” during recessions. This increased threat of expropriation depresses investment, prolonging downturns. It is the incompleteness of financial markets and the lack of commitment that generate investment cycles even in an environment where first-best capital stock is constant.

Investment Creation and Real Exchange Rates in a Model with Search Frictions

Foreign Investment is modeled as the outcome of a search process that emphasizes the distinction between investment creation and investment destruction processes which underlie net flows. The optimal q is shown to equal the difference between a naive net present value calculation and the call option of further search. The investment mechanism is embedded in a two-sector dynamic small open-economy model to derive the response of the economy to a capital market liberalization. The presence of an option value to search is shown to generate dynamics in investment inflows, which when combined with the saving-production decisions of households, generates co-movement in real exchange rates, consumption, current account deficits and non-traded sector output which closely resembles the experience of several Latin-American countries, starting in the late nineteen eighties. The search approach to investment contrasts with the standard q-theory approach which generates counterfactual predictions in this framework. Lastly, the paper evaluates the effect of cyclical shocks on direct investment decisions and provides an argument for the observed stability of these flows.

Banking, Trade, and the making of a Dominant Currency

We explore the interplay between trade invoicing patterns and the pricing of safe assets in different currencies. Our theory highlights the following points: 1) a currency’s role as a unit of account for invoicing decisions is complementary to its role as a safe store of value; 2) this complementarity can lead to the emergence of a single dominant currency in trade invoicing and global banking, even when multiple large candidate countries share similar economic fundamentals; 3) firms in emerging-market countries endogenously take on currency mismatches by borrowing in the dominant currency; 4) the expected return on dominant-currency safe assets is lower than that on similarly safe assets denominated in other currencies, thereby bestowing an “exorbitant privilege�? on the dominant currency. The theory thus provides a unified explanation for why a dominant currency is so heavily used in both trade invoicing and in global finance.

Global Trade and the Dollar

We document that the U.S. dollar exchange rate drives global trade prices and volumes. Using a newly constructed data set of bilateral price and volume indices for more than 2,500 country pairs, we establish the following facts: 1) The dollar exchange rate quantitatively dominates the bilateral exchange rate in price pass-through and trade elasticity regressions. U.S. monetary policy induced dollar fluctuations have high pass-through into bilateral import prices. 2) Bilateral non-commodities terms of trade are essentially uncorrelated with bilateral exchange rates. 3) The strength of the U.S. dollar is a key predictor of rest-of-world aggregate trade volume and consumer/producer price inflation. A 1 percent U.S. dollar appreciation against all other currencies in the world predicts a 0.6–0.8 percent decline within a year in the volume of total trade between countries in the rest of the world, controlling for the global business cycle. 4) Using a novel Bayesian semiparametric hierarchical panel data model, we estimate that the importing country’s share of imports invoiced in dollars explains 15 percent of the variance of dollar pass-through/elasticity across country pairs. Our findings strongly support the dominant currency paradigm as opposed to the traditional Mundell-Fleming pricing paradigms.
