Abstract:

This paper investigates the impact of the asymmetric shocks within a currency union in a framework that takes account of the zero bound constraint on policy rates, and also allows for constraints on fiscal policy. In this environment, we document that the usual optimal currency argument showing that the effects of shocks are mitigated to the extent that they are common across member states can be reversed. Countries can be worse off when their neighbors experience similar shocks, including policy-driven reductions in government spending.

Abstract:

We examine the impact of fiscal positions, both the level of debt and the fiscal balance, on long-term government bond yields in the OECD. In order to control for the endogenity of fiscal positions to the business cycle we utilize forward projections of fiscal positions from the OECD's Economic Outlook. In a panel regression over the period from 1988 to 2007, we find a robust and significant effect of fiscal performance on long-term bond yields. Our estimates imply that the marginal effect of the projected deterioration of fiscal positions associated with the recent financial crisis is to add about 60 basis points to U.S. bond yields by 2015, with effects on other G7 bond yields generally being smaller.

Abstract:

A key feature of the 2007-2008 financial crisis is that for some classes of securities trade has ceased. And where trade does occur, it appears that market prices are well below what one might believe to be the intrinsic value for that class of security. This seems to be especially true for those securities where the payoff streams are particularly complex (for example, CDOs). One explanation for this is that information about these securities' intrinsic values is asymmetric, with the current holders having better information than potential buyers. We show how the resulting adverse selection problem can help explain why more complex securities trade at significant discounts to their intrinsic values or do not trade at all. To examine whether asymmetric information alone would suffice to shut down portions of the asset-backed securities (ABS) market, we append a simple "workhorse" model for pricing securities under asymmetric information into a Monte Carlo simulation that generates hypothetical securities backed by residential mortgages. We conduct a type of "stress test" on the ABS by making the distribution of payoffs to the underlying loans worse, and find that the intrinsic values of the securities further down the securitization chain become dispersed in such a way that the market for them may shut down under asymmetric information. We then consider the role for government intervention, and compare the effectiveness of different policies that aim to unclog these markets.

Abstract:

Beginning in 2009, in many advanced economies, policy rates reached their zero lower bound (ZLB). Almost at the same time, oil prices started rising again. We analyze how the ZLB affects the propagation of oil shocks. As these shocks move inflation and output in opposite directions, their effects on economic activity are cushioned when monetary policy is constrained. The burst of inflation from an oil price increase lowers real interest rates at the ZLB and stimulates the interest-sensitive component of GDP, offsetting the usual contractionary effects. In fact, if the increase in oil prices is gradual, the persistent rise in inflation can cause a GDP expansion.

Abstract:

The degree of exchange-rate pass-through to import prices is low. An average pass-through estimate for the 1980s would be roughly 50 percent for the United States implying that, following a 10 percent depreciation of the dollar, a foreign exporter selling to the U.S. market would raise its price in the United States by 5 percent. Moreover, substantial evidence indicates that the degree of pass-through has since declined to about 30 percent.

Gust, Leduc, and Vigfusson (2010) demonstrate that, in the presence of pricing complementarity, trade integration spurred by lower costs for importers can account for a significant portion of the decline in pass-through. In our framework, pass-through declines solely because of markup adjustments along the intensive margin.

In this paper, we model how the entry and exit decisions of exporting firms affect pass-through. This is particularly important since the decline in pass-through has occurred as a greater concentration of foreign firms are exporting to the United States.

We find that the effect of entry on pass-through is quantitatively small and is more than offset by the adjustment of markups that arise only along the intensive margin. Even though entry has a relatively small impact on pass-through, it nevertheless plays an important role in accounting for the secular rise in imports relative to GDP. In particular, our model suggests that over 3/4 of the rise in the U.S. import share since the early 1980s is due to trade in new goods. Thus, a key insight of this paper is that adjustment of markups that occur along the intensive margin are quantitatively more important in accounting for secular changes in pass-through than adjustments that occur along the extensive margin.

Abstract:

The rapid growth of offshoring has sparked a contentious debate over its impact on the U.S. manufacturing sector, which has recorded steep employment declines yet strong output growth--a fact reconciled by the notable gains in manufacturing productivity. We maintain, however, that the dramatic acceleration of imports from developing countries has imparted a significant bias to the official statistics. In particular, the price declines associated with the shift to low-cost foreign suppliers are generally not captured in input cost and import price indexes. Although cost savings are a primary driver of the shift in sourcing to foreign suppliers, the price declines associated with offshoring are not systematically observed; this is the essence of the measurement problem. To gauge the magnitude of these discounts, we draw on a variety of evidence from import price microdata from the Bureau of Labor Statistics, industry case studies, and the business press. To assess the implications of offshoring bias for manufacturing productivity and value added, we implement the bias correction developed by Diewert and Nakamura (2009) to the input price index in a growth accounting framework, using a variety of assumptions about the magnitude of the discounts from offshoring. We find that from 1997 to 2007 average annual multifactor productivity growth in manufacturing was overstated by 0.1 to 0.2 percentage point and real value added growth by 0.2 to 0.5 percentage point. Furthermore, although the bias from offshoring represents a relatively small share of real value added growth in the computer and electronic products industry, it may have accounted for a fifth to a half of the growth in real value added in the rest of manufacturing.

Abstract:

Emerging market (EM) assets have historically been regarded as inherently risky and particularly vulnerable to international shocks that result in a general increase in investor risk perceptions. In this paper, we assess the ongoing relevance of this view by examining the linkages between EM and non-EM stock and bond markets in the past two decades, with a focus on how these relationships played out during the global financial crisis of 2007-2009. We evaluate how these linkages have evolved over the period 1992-2009, through statistical tests of whether the volatility of EM financial markets changed - either in their response to international shocks originating in advanced economy markets or in their independent fluctuations. We find that over the longer period EM bond and stock prices have on average moved in the same direction as the prices of non-EM risky assets, and this co-movement has persisted. However, these relationships have evolved somewhat over time. Both EM sensitivity to international shocks and EM-specific volatility in EM sovereign bond spreads appear to have decreased over time, consistent with the greater fundamental stability of EM economies and perhaps a reduced inclination by investors to sell off EM assets in response to a rise in risk perceptions. Somewhat in contrast, while an upward trend in co-variation between EM and non-EM stock prices suggests an increasing degree of global market integration, idiosyncratic volatility has declined, consistent with a diminished level of locally-driven risk in these markets. In addition, the response of EM asset prices to the latest financial crisis appears to be moderate in comparison to historical experience. This evidence may reflect reduced EM vulnerability to external shocks in general, which is consistent with some encouraging improvements in the underlying fundamentals of EM economies over the decade preceding the onset of the crisis.

Abstract:

We demonstrate that the parameters controlling skewness and kurtosis in popular equity return models estimated at daily frequency can be obtained almost as precisely as if volatility is observable by simply incorporating the strong information content of realized volatility measures extracted from high-frequency data. For this purpose, we introduce asymptotically exact volatility measurement equations in state space form and propose a Bayesian estimation approach. Our highly efficient estimates lead in turn to substantial gains for forecasting various risk measures at horizons ranging from a few days to a few months ahead when taking also into account parameter uncertainty. As a practical rule of thumb, we find that two years of high frequency data often suffice to obtain the same level of precision as twenty years of daily data, thereby making our approach particularly useful in finance applications where only short data samples are available or economically meaningful to use. Moreover, we find that compared to model inference without high-frequency data, our approach largely eliminates underestimation of risk during bad times or overestimation of risk during good times. We assess the attainable improvements in VaR forecast accuracy on simulated data and provide an empirical illustration on stock returns during the financial crisis of 2007-2008.

Abstract:

We build and estimate a two-sector (goods and services) dynamic stochastic general equilibrium model with two types of inventories: materials (input) inventories facilitate the production of finished goods, while finished goods (output) inventories yield utility services. The model is estimated using Bayesian methods. The estimated model replicates the volatility and cyclicality of inventory investment and inventory-to-target ratios. Although inventories are an important element of the model's propagation mechanism, shocks to inventory efficiency or management are not an important source of business cycles. When the model is estimated over two subperiods (pre and post 1984), changes in the volatility of inventory shocks or in structural parameters associated with inventories, such as the input inventory to output ratio, play a small role in reducing the volatility of output.

Abstract:

This paper uses a DSGE model to examine the effects of an expansion in government spending in a liquidity trap. If the liquidity trap is very prolonged, the spending multiplier can be much larger than in normal circumstances, and the budgetary costs minimal. But given this "fiscal free lunch," it is unclear why policymakers would want to limit the size of fiscal expansion. Our paper addresses this question in a model environment in which the duration of the liquidity trap is determined endogenously, and depends on the size of the fiscal stimulus. We show that even if the multiplier is high for small increases in government spending, it may decrease substantially at higher spending levels; thus, it is crucial to distinguish between the marginal and average responses of output and government debt.

Abstract:

This paper reviews the available evidence and previous research on potential effects of financial globalization, that is, the international integration of financial markets. In particular, we address the questions: Has financial globalization materially increased the influence of external developments on domestic monetary conditions? And, has it reduced the influence of central banks over financial and economic conditions in their own country? We find that central banks with floating currencies retain the ability to independently determine short-term interest rates and thus influence broader financial conditions and macroeconomic performance in their economies. However, domestic financial conditions appear to have become more vulnerable to a wide range of external shocks, complicating the task of making appropriate monetary policy decisions. Moreover, the financial crisis has highlighted the importance of cross-border channels for the transmission of liquidity and credit shocks. With financial transactions increasingly being undertaken in vehicle currencies such as dollars and euros, the liquidity provision and the lender-of-last resort functions of many central banks are being challenged. Accordingly, international arrangements for liquidity provision may become increasingly important in the future.

Abstract:

When the nominal interest rate reaches its zero lower bound, credibility is crucial for conducting forward guidance. We determine optimal policy in a New Keynesian model when the central bank has imperfect credibility and cannot set the nominal interest rate below zero. In our model, an announcement of a low interest rate for an extended period does not necessarily reflect high credibility. Even if the central bank does not face a temptation to act discretionarily in the current period, policy commitments should not be postponed. In reality, central banks are often reluctant to allow a recovery path with output and inflation temporarily above target. From the perspective of our model such a policy reflects a low degree of credibility. We find increased forecast uncertainty in inflation and the output gap at the zero lower bound while interest rate uncertainty is reduced. Furthermore, misalignments between announced interest rate paths and market expectations are found to be best explained by lack of credibility.

Abstract:

Investment-specific technology (IST) shocks are often interpreted as multi-factor productivity (MFP) shocks in a separate investment-producing sector. However, this interpretation is strictly valid only when some stringent conditions are satisfied. Some of these conditions are at odds with the data. Using a two-sector model whose calibration is based on the U.S. Input-Output Tables, we consider the implications of relaxing several of these conditions. In particular, we show how the effects of IST shocks in a one-sector model differ from those of MFP shocks to an investment-producing sector of a two-sector model. Importantly, with a menu of shocks drawn from recent empirical studies, MFP shocks induce a positive short-run correlation between consumption and investment consistent with U.S. data, while IST shocks do not.

Abstract:

We use a DSGE model that generates endogenous movements in risk premia to examine the positive and normative implications of alternative monetary policy rules. As emphasized by the microfinance literature, variation in risk arises because households face fixed costs of transferring cash across financial accounts, implying that some households rebalance their portfolios infrequently. We show that the model can account for the mean returns on equity and the risk-free rate, and in line with empirical evidence generates a decline in the equity premium following an unanticipated easing of monetary policy. An important result that emerges from our analysis is that countercyclical monetary policy generates higher average welfare than constant money growth or zero inflation policies.

Abstract:

Using data on border enforcement and macroeconomic indicators from the U.S. and Mexico, we estimate a two-country business cycle model of labor migration and remittances. The model matches the cyclical dynamics of unskilled migration, and documents the insurance role of remittances in consumption smoothing. Over the cycle, immigration increases with the expected stream of future wage gains, but it is dampened by a sunk emigration cost. Migration barriers slow the adjustment of the stock of immigrant labor, enhancing the volatility of unskilled wages and remittances. Changes in border enforcement have asymmetric welfare implications for the skilled and unskilled households.

Abstract:

This paper builds a model of sovereign debt in which default risk, interest rates, and debt depend not only on current fundamentals but also on news about future fundamentals. News shocks affect equilibrium outcomes because they contain information about the future ability of the government to repay its debt. First, in the model with news shocks not all defaults occur in bad times, bringing the model closer to the data. Second, the news shocks help account for key differences between emerging markets and developed economies: as the precision of the news improves the model predicts lower variability of consumption, less countercyclical trade balance and interest rate spreads, as well as a higher level of debt more in line with the characteristics of developed economies. Finally, the model also captures the hump-shaped relationship between default rates and the precision of news obtained from the data.

Abstract:

This paper reviews the experience of eight major foreign central banks with policy interest rates comparable to the interest rate on excess reserves paid by the Federal Reserve. We pursue two main lines of inquiry: 1) To what extent have these policy interest rates been lower bounds for short-term market rates, and 2) to what extent has tightening that included increasing these policy rates been achieved without reliance on reductions in reserves or other deposits held at the central bank? The foreign experience suggests that policy rate floors can be effective lower bounds for market rates, although incomplete access to central bank accounts and interest on them weakens this result. In addition, the foreign experience suggests that tightening by increasing the interest rate paid on central bank balances can help reduce or eliminate the need to drain balances. These results are consistent with theoretical results that show that tightening without draining is possible, irrespective of whether excess reserves are large or small.

Abstract:

Cross-country variation in production costs encourages firms to relocate production to other countries, a process known as offshoring through vertical foreign direct investment (FDI). To examine the effect of offshoring through vertical FDI on the international transmission of business cycles, I propose a model that distinguishes between fluctuations in the number of offshoring firms (the extensive margin) and in the value added per offshoring firm (the intensive margin) as separate transmission mechanisms. In the model, firms face a sunk cost to enter the domestic market, and an additional fixed cost to produce offshore. The offshoring decision depends on the firm-specific productivity and on fluctuations in the relative cost of effective labor. The model replicates the procyclical pattern of offshoring, as well as the dynamics along its extensive and intensive margins, which I document using data from U.S. manufacturing and Mexico's maquiladora sector. In addition, offshoring enhances the co-movement of output across countries, in line with existing empirical evidence. The result is closely related to the dynamics of offshoring along its extensive and intensive margins.

Abstract:

The global financial crisis clearly started with problems in the U.S. subprime sector and spread across the world from there. But was the direct exposure of foreigners to the U.S. financial system a key driver of the crisis, or did other factors account for its rapid contagion across the world? To answer this question, we assessed whether countries that held large amounts of U.S. mortgage-backed securities (MBS) and were highly dependent on dollar funding experienced a greater degree of financial distress during the crisis. We found little evidence of such "direct contagion" from the United States to abroad. Although CDS spreads generally rose higher and bank stocks generally fell lower in countries with more exposure to U.S. MBS and greater dollar funding needs, these correlations were not robust, and they fail to explain the lion's share of the deterioration in asset prices that took place during the crisis. Accordingly, channels of "indirect contagion" may have played a more important role in the global spread of the crisis: a generalized run on global financial institutions, given the opacity of their balance sheets; excessive dependence on short-term funding; vicious cycles of mark-to-market losses driving fire sales of MBS; the realization that financial firms around the world were pursuing similar (flawed) business models; and global swings in risk aversion. The U.S. subprime crisis, rather than being a fundamental driver of the global crisis, may have been merely a trigger for a global bank run and for disillusionment with a risky business model that already had spread around the world.

Abstract:

We examine the importance of incorporating macroeconomic information and, in particular, accounting for model uncertainty when forecasting the term structure of U.S. interest rates. We start off by analyzing and comparing the forecast performance of several individual term structure models. Our results confirm and extend results found in previous literature that adding macroeconomic information, through factors extracted from a large number of individual series, tends to improve interest rate forecasts. We then show, however, that the predictive power of individual models varies over time significantly. Models with macro factors are the more accurate in and around recession periods. Models without macro factors do particularly well in low-volatility subperiods such as the late 1990s. We demonstrate that this problem of model uncertainty can be mitigated by combining individual model forecasts. Combining forecasts leads to encouraging gains in predictability, especially for longer-dated maturities, and importantly, these gains are consistent over time.

Abstract:

Understanding the joint dynamics of international prices and quantities remains a central issue in international business cycles. International relative prices appreciate when domestic consumption and output increase more than their foreign counterparts. In addition, both trade flows and trade prices display sizable volatility. This paper incorporates Hicks-neutral and investment-specific technology shocks into a standard two-country general equilibrium model with variable capacity utilization and weak wealth effects on labor supply. Investment-specific technology shocks introduce a source of fluctuations in absorption similar to taste shocks, thus reconciling theory and data. The paper also presents implications for the transmission mechanism of technology shocks across countries and for the Barro and King (1984) critique of investment shocks.

Abstract:

A key emerging insight in international economics is that the scope for quality differentiation can help to explain patterns in export prices at the level of products or firms. In this paper, a unified theoretical framework of firm heterogeneity in cost and quality is brought to bear on an expansive data set of U.S. import transaction prices collected by the Bureau of Labor Statistics (BLS). The higher moments of the price distribution are used to identify the scope for quality differentiation at the detailed product level; highly differentiated products account for about half of U.S. import value. The product classification is then used to evaluate two claims in the nascent firm-level trade quality literature. First, the positive link between exporter capability and price is found to depend on the nature of the product: productive exporters simultaneously specialize in high-priced varieties in quality differentiated goods and low-priced varieties in more homogeneous goods. Second, a novel time series test documents firm sorting into export markets according to output quality.

Abstract:

This paper formulates and estimates a three-shock US business cycle model. The estimated model accounts for a substantial fraction of the cyclical variation in output and is consistent with the observed inertia in inflation. This is true even though firms in the model reoptimize prices on average once every 1.8 quarters. The key feature of our model underlying this result is that capital is firm-specific. If we adopt the standard assumption that capital is homogeneous and traded in economy-wide rental markets, we find that firms reoptimize their prices on average once every 9 quarters. We argue that the micro implications of the model strongly favor the firm-specific capital specification.
