Real exchange rates and real interest rate differentials: A present value interpretation

Although the real exchange rate-real interest rate (RERI) relationship is central to most open economy macroeconomic models, empirical support for the relationship is generally found to be rather weak. In this paper we re-investigate the RERI relationship using bilateral US real exchange rate data spanning the period 1978-2007. Instead of testing one particular model, we build on Campbell and Shiller [1987. Cointegration tests of present-value models. Journal of Political Economy 95, 1062-1088] to propose a metric of the economic significance of the relationship. Our empirical results provide robust evidence that the RERI link is economically significant and that the real interest rate differential is a reasonable approximation of the expected rate of depreciation over longer horizons.     

Sudden stops and the Mexican wave: Currency crises,capital flow reversals and output loss in emerging markets

Sudden stops are the simultaneous occurrence of a currency/balance of payments crisis with a reversal in capital flows. We investigate whether sudden-stop crises are a unique phenomenon and whether they entail an especially large and abrupt pattern of output collapse (a “Mexican wave”). Using a panel data set over 1975–1997 and covering 24 emerging-market economies, we distinguish between the output effects of currency crises, capital inflow reversals, and sudden-stop crises. Sudden-stop crises have a large negative, but short-lived, impact on output growth over and above that found with currency crises. A currency crisis typically reduces output by about 2–3%, while a sudden stop reduces output by an additional 6–8% in the year of the crisis. The cumulative output loss of a sudden stop is even larger, around 13–15% over a 3-year period. Our model estimates correspond closely to the output dynamics of the ‘Mexican wave’ (such as seen in Mexico in 1995, Turkey in 1994 and elsewhere), and out-of-sample predictions of the model explain well the sudden (and seemingly unexpected) collapse in output associated with the 1997–1998 Asian Crisis.     

External wealth, the trade balance, and the real exchange rate

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.     

Deforestation and the real exchange rate

Deforestation is a phenomenon that has largely been concentrated in the developing world. We construct a theoretical model of deforestation that focuses on the factors affecting the incentives to transform forested land into agricultural land. We show that: (i) lower discount rates and stronger institutions decrease deforestation; (ii) a depreciation in the real exchange rate increases deforestation in developing countries whereas the opposite obtains in developed countries; (iii) paradoxically, better institutions may exacerbate the deleterious impact of a depreciation in developing countries. These hypotheses are tested on an annual sample of 101 countries over the 1961–1988 period, and are not rejected by the data. Our results suggest that short-term macroeconomic policy, institutional factors, and the interaction between the two, are potentially important determinants of environmental outcomes.     

Sudden stops: Determinants and output effects in the first era of globalization, 1880-1913

We study the determinants and output effects of sudden stops in capital inflows during an era of intensified globalization from 1880 to 1913. Higher levels of exposure to foreign currency debt and large current account deficits associated with reliance on foreign capital greatly increased the likelihood of experiencing a sudden stop. Trade openness and strong reserve positions had the opposite effect. Sudden stops accompanied by financial crises are associated with drops in output per capita below trend equal to three to four percent. Frictions in the international capital markets of the day are a likely candidate for these output losses. Sudden stops connected with crises do not seem to bring trend growth downwards. Sudden stops not connected with crises appear to be associated with significant declines in trend growth.     

Non linear and asymmetric linkages between real growth in the Euro area and global financial market conditions: New evidence

This paper deals with transition mechanisms through which financial market conditions affect real economic growth in the Euro area. The informational content of financial variables for predicting real economic growth is assessed, allowing for asymmetric responses to shocks. A nonlinear framework is developed based on a smooth transition model for which the effects of shocks can vary across business cycles when financial indicators modify both the endogenous and state variables. Global financial variables are shown to significantly affect real growth in the Euro area, particularly during periods of recession. Changes in stock market index and yield slope have asymmetric effects on real growth. In recessionary periods, the slope of the US yield curve does not have a significant impact on growth in the Euro area.     

Fertility and the real exchange rate

Abstract .  We use a quinquennial data set covering 87 countries between 1975 and 2005 to investigate empirically the relationship between fertility and the real effective exchange rate. Theoretically, a country experiencing a decline in its fertility rate can be expected to experience a real depreciation. We test and confirm this hypothesis, controlling for a number of other potential determinants. We find a statistically significant and robust link between fertility and the exchange rate. Our point-estimate is that a decline in the fertility rate of one child per woman is associated with a depreciation of approximately 15% in the real effective exchange rate.     

Bankruptcy costs, liability dollarization, and vulnerability to sudden stops

Countries with intermediate levels of institutional quality suffer larger output contractions following sudden stops of capital inflows than less developed nations. However, countries with strong institutions seldom experience significant falls in output after capital flow reversals. We reconcile these two observations using a calibrated DSGE model that extends the financial accelerator framework developed in Bernanke, Gertler and Gilchrist (1999). The model captures financial market institutional quality with creditors' ability to recover assets from bankrupt firms. Bankruptcy costs affect vulnerability to sudden stops directly but also indirectly by affecting the degree of liability dollarization. Simulations reveal an inverted U-shaped relationship between bankruptcy costs and the output loss following sudden stops.     

Globalization, rent protection institutions, and going alone in freeing trade

We construct a two-country North-South Product-cycle model of trade with endogenous growth and trade barriers. We remove the scale effects on growth by incorporating rent protection activities by Northern incumbents. We examine the effects of two forms of globalization - an expansion of the relative size of the South and unilateral trade liberalization by either country. We find that the location of rent protection institutions and the sectoral trade structure determine whether or not globalization raises steady-state economic growth. We demonstrate that for accelerating worldwide economic growth, contrary to conventional wisdom, unilateral Northern trade liberalization is preferable to bilateral trade liberalization.     

Financial constraints,firm entry,and exchange rate pass-through

Using a heterogeneous firm model with firm entry and endogenous markups, I study how the financial constraints of exporting firms affect exchange rate pass-through behaviors. I find that the financial constraints increase the degree of exchange rate pass-through.     

Increasing Returns,Financial Capital Mobility and Real Exchange Rate Dynamics*

The late 1990s saw a US IT investment boom, large capital flows into the USA and an appreciation of the US$. At the time, this appeared to be driven by expectations of continued IT‐related knowledge spillover externalities and associated productivity and profit growth. Using a two‐region dynamic general equilibrium model with externalities, we find a once‐off productivity shock leads to capital inflow and a real appreciation only in the short term. In the long term, capital flows stabilise and the real exchange rate depreciates. For a single shock to trigger long‐term growth in capital flows requires unrealistically large externalities.     

Currency crises and the real economy: The role of banks

This paper attempts to explain the divergent output effects of currency crises through a very simple and intuitive model that relates the effects of a devaluation not only to the financial fragility of banks, but also to the degree of financial market imperfection. The model shows that countries with higher degrees of financial market imperfection and/or a banking sector whose balance sheets are weak, in terms of having low net worth and high foreign currency exposure, are much more likely to suffer a contraction in the wake of a currency crisis.     

International trade, exhaustible-resource abundance and economic growth

Countries with oil and other natural resources have grown less rapidly than those countries without. This phenomenon is known as the “natural resource curse”. We develop an infinite-horizon, two-country model of trade in which countries are identical, except that one country is endowed with deposits of an exhaustible resource and the other is not. Within the context of the model, we show that this phenomenon can be explained in part by an inelastic demand for the exhaustible resource that increases growth in trade revenues and induces the resource-abundant country to invest relatively less than the country lacking in exhaustible resources. These results are derived analytically and illustrated by an empirical analysis based on plausible parameters obtained from data.     

Panel cointegration and the monetary exchange rate model

This paper re-examines the validity of the monetary exchange rate model during the post-Bretton Woods era for 18 OECD countries. Our analysis simultaneously considers the presence of both cross-sectional dependence and multiple structural breaks, which have not received much attention in previous studies of the monetary model. The empirical results indicate that the monetary model emerges only when the presence of structural breaks and cross-country dependence has been taken into account. Evidence is also provided suggesting that the breaks in the monetary model can be derived from the underlying purchasing power parity relation.     

Cross‐border mergers and acquisitions: does the exchange rate matter? Some evidence for Canada

Abstract.  Theoretical and empirical studies investigating the relationship between the exchange rate and FDI have generated mixed results. Using bilateral Canadian-U.S. industry level count data on cross-border mergers and acquisitions (M&As) and conditioning on industry tariff rates, value added share of industries, industry M&A trend activity, and the number of establishments, we find evidence that a real dollar depreciation of the home currency leads to an increase in the probability of foreign M&As but only in high R&D industries. These empirical results are consistent with Blonigen's asset acquisition hypothesis. Results on European M&As of Canadian firms also lean towards this result.     

Limited asset market participation and the consumption‐real exchange rate anomaly

Abstract Under efficient consumption risk sharing, as assumed in standard international business cycle models, a country's aggregate consumption rises relative to foreign consumption, when the country's real exchange rate depreciates. Yet empirically, relative consumption and the real exchange rate are essentially uncorrelated. This paper shows that this ‘consumption‐real exchange rate anomaly’ can be explained by a simple model in which a subset of households trade in complete financial markets, while the remaining households lead hand‐to‐mouth (HTM) lives. HTM behaviour also generates greater volatility of the real exchange rate and of net exports, which likewise brings the model closer to the data.     

Sudden stops, financial frictions, and labor market flows: Evidence from Latin America

While the aggregate effects of sudden stops and international financial crises are well known, the disaggregated channels through which they work are not well explored yet. In this paper, using job flows from a sectoral panel dataset for four Latin American countries, we find that sudden stops are characterized as periods of lower job creation and increased job destruction. Moreover, these effects are heterogeneous across sectors: we find that when a sudden stop occurs, sectors with higher dependence on external financing experience lower job creation. In turn, sectors with higher liquidity needs experience significantly larger job destruction. This evidence is consistent with the idea that dependence on external financing affects mainly the creation margin and that exposure to liquidity conditions affects mainly the destruction margin. Overall, our results provide evidence of financial frictions being an important transmission channel of sudden stops and in the restructuring process in general.     

ENDOGENOUS FLUCTUATIONS IN TWO‐COUNTRY MODELS*

This paper investigates the interlinkage in the business cycles of large‐country economies in a free‐trade equilibrium. We consider a two‐country, two‐good, two‐factor general equilibrium model with Cobb‐Douglas technologies and linear preferences. We also assume decreasing returns to scale in the consumption good sector. We first identify the determinants of each country's global accumulation pattern in autarky equilibrium, and secondly we show how a country's business cycles may spread throughout the world once trade opens. We thus give capital intensity conditions for local and global stability of competitive equilibrium paths.     

PRODUCTIVE GOVERNMENT SPENDING,PATTERNS OF SPECIALIZATION AND ECONOMIC GROWTH IN A SMALL OPEN ECONOMY*

Constructing a two‐sector small open endogenous growth model with productive government spending, this paper examines patterns of specialization and the growth effects of fiscal policy. It is shown in this model that a change in income tax rate can cause a change in an equilibrium pattern of specialization. Because of this property, the relationship between the tax rate and the growth rate yields either a humped shape or a two‐humped shape, depending on world commodity prices. We also show that the growth maximizing tax rate is not necessarily equal to the tax rate that maximizes the level of social welfare.     

Aid,non‐traded goods,and growth

Abstract We examine the effects of foreign aid in a small recipient country with two traded goods, one non‐traded good, and two factors. Learning by doing and intersectoral knowledge spillovers contribute to endogenous growth. We obtain two main results. First, a permanent increase in untied aid raises (or lowers) the growth rate if and only if the non‐traded good is more capital intensive (or effective labour intensive) than the operating traded good. Second, a permanent increase in untied aid raises welfare if the non‐traded good is more capital intensive than the operating traded good; otherwise, it may raise or lower welfare.
