Securing the Peace after a Truce in the War on Inflation

Central bankers in the major industrial economies have come close to securing the peace, or in some cases, have secured it in the battle against inflation, hostilities that lasted almost as long as the Cold War. It is important to remember that this battle has been a good fight: both the theory and the empirics reviewed in this paper support the central tenet of central banking that lower inflation supports faster economic growth. However, the observation that low inflation is associated with a macroeconomic benefit does not imply that disinflation should be pursued without limit. A particularly compelling argument in the body of work on the optimal inflation rate is the view that price deflation, or even very low inflation, may pose unacceptable macroeconomic risks given the lower bound of nominal interest rates of zero. Empirical work in this paper suggests that the zero bound is not an artifact of theoreticians but a palpable reality. That said, the perils of the zero bound to nominal interest rates may be seen as less threatening if a central bank is willing to be both aggressive in providing policy accommodation when the economy may be nearing the zero bound and flexible in using the available tools of policy.

Twin Fallacies About Exchange Rate Policy in Emerging Markets

Two assertions about exchange rate regimes circulate with some frequency in policy circles. The first, the hypothesis of the excluded middle, holds that authorities must either choose perfectly floating exchange rates (preferably anchored by an inflation target for the central bank) or a hard (preferably irrevocable) peg. The second, seemingly unrelated, argues that the inability of emerging market economies to exercise monetary independence owes to the severe mistrust that they are perceived with by global investors because of the economic failures of prior governments. This paper argues that the theories of the excluded middle and original sin are twin and related fallacies that are contrary to theory and evidence. This paper will provide a model in which the government can choose policies consistent with either a pure float anchored by a constant money stock or a pure peg but, under certain circumstances, fail to find exchange rate stability at either corner. The problem is that the potential for regime change implies that the current government's successors may behave less admirably, which will weigh on investors' current behavior. The difficulties imparted by this expectation channel in an otherwise standard model of optimizing agents endowed with rational expectations shows both why looking back to explain credibility problems is looking the wrong way and why the excluded middle is, in fact, so crowded.

What Hurts Most? G-3 Exchange Rate or Interest Rate Volatility

With many emerging market currencies tied to the U.S. dollar either implicitly or explicitly, movements in the exchange values of the currencies of major countries have the potential to influence the competitive position of many developing countries. According to some analysts, establishing target bands to reduce the variability of the G-3 currencies would limit those destabilizing shocks emanating from abroad. This paper examines the argument for such a target zone strictly from an emerging market perspective. Given that sterilized intervention by industrial economies tends to be ineffective and that policy makers show no appetite to return to the controls on international capital flows that helped keep exchange rates stable over the Bretton Woods era, a commitment to damping G-3 exchange rate fluctuations requires a willingness on the part of G-3 authorities to use domestic monetary policy to that end. Under a system of target zones, then, relative prices for emerging market economies may become more stable, but debt-servicing costs may become less predictable. We use a simple trade model to show that the resulting consequences for welfare are ambiguous. Our empirical work supplements the traditional literature on North-South links by examining the importance of the volatilities of G-3 exchange-rates, and U.S. interest rate and consumption on capital flows and economic growth in developing countries over the past thirty years.

Capital Flow Bonanzas: An Encompassing View of the Past and Present

A considerable literature has examined the causes, consequences, and policy responses to surges in international capital flows. A related strand of papers has attempted to catalog current account reversals and capital account "sudden stops." This paper offers an encompassing approach with an algorithm cataloging capital inflow bonanzas in both advanced and emerging economies during 1980-2007 for 181 countries and 1960-2007 for a subset of 66 economies from all regions. In line with earlier studies, global factors, such as commodity prices, international interest rates, and growth in the world's largest economies, have a systematic effect on the global capital flow cycle. Bonanzas are no blessing for advanced or emerging market economies. In the case of the latter, capital inflow bonanzas are associated with a higher likelihood of economic crises (debt defaults, banking, inflation and currency crashes). Bonanzas in developing countries are associated with procyclical fiscal policies and attempts to curb or avoid an exchange rate appreciation -- very likely contributing to economic vulnerability. For the advanced economies, the results are not as stark, but bonanzas are associated with more volatile macroeconomic outcomes for GDP growth, inflation, and the external accounts. Slower economic growth and sustained declines in equity and housing prices follow at the end of the inflow episode.

After the Fall

This paper examines the behavior of real GDP (levels and growth rates), unemployment, inflation, bank credit, and real estate prices in a twenty one-year window surrounding selected adverse global and country-specific shocks or events. The episodes include the 1929 stock market crash, the 1973 oil shock, the 2007 U.S. subprime collapse and fifteen severe post-World War II financial crises. The focus is not on the immediate antecedents and aftermath of these events but on longer horizons that compare decades rather than years. While evidence of lost decades, as in the depression of the 1930s, 1980s Latin America and 1990s Japan are not ubiquitous, GDP growth and housing prices are significantly lower and unemployment higher in the ten-year window following the crisis when compared to the decade that preceded it. Inflation is lower after 1929 and in the post-financial crisis decade episodes but notoriously higher after the oil shock. We present evidence that the decade of relative prosperity prior to the fall was importantly fueled by an expansion in credit and rising leverage that spans about 10 years; it is followed by a lengthy period of retrenchment that most often only begins after the crisis and lasts almost as long as the credit surge.

FLUCTUACIONES DEL PRODUCTO Y CHOQUE MONETARIOS: EVIDENCIA COLOMBIANA

Usando información anual para Colombia en los últimos treinta años y una batería nueva de técnicas econométricas, evaluamos dos teorías opuestas que explican las fluctuaciones económicas: la síntesis neoclásica, que plantea que en presencia de rigidez temporal en los precios, una expansión monetaria no anticipada produce ganancias de producto que se desvanecen en el tiempo con incrementos del nivel de precios; y una explicación alternativa, que se centra en choques tecnológicos y de preferencia reales" como fuente de las variaciones en el producto.
