Aggregate Hours Worked in OECD Countries: New Measurement and Implications for Business Cycles

Lee E. Ohanian and Andrea Raffo

Abstract:

We build a dataset of quarterly hours worked for 14 OECD countries. We document that hours are as volatile as output, that a large fraction of labor adjustment takes place along the intensive margin, and that the volatility of hours relative to output has increased over time. We use these data to reassess the Great Recession and prior recessions. The Great Recession in many countries is a puzzle in that labor wedges are small, while those in the U.S. Great Recession - and those in previous European recessions - are much larger.

Exports Versus Multinational Production Under Nominal Uncertainty

Abstract:

This paper examines how nominal uncertainty affects the choice firms face to serve a foreign market through exports or to produce abroad as a multinational. I develop a two-country, stochastic general equilibrium model in which firms make production and pricing decisions in advance, and I consider its implications on this relative choice. For foreign firms, both exports and multinational production are priced in the destination currency, and this uncertainty has no effect on the relative decision. In the data, U.S. firms set nearly all of their export prices in dollars. Therefore, home firms price exports in their own currency in the model. Home exporters gain an advantage over home multinationals: during a foreign contraction, the foreign exchange rate appreciates, causing exported goods from the home country to be relatively cheaper. This pricing advantage affects exporters non-linearly through demand, which translates to convex profits. As foreign volatility rises, the model implies that the home country should serve the foreign country relatively more through exports. I take this implication to bilateral U.S. data, using inflation volatility as a proxy for nominal volatility. Using sectoral data on sales by majority-owned foreign affiliates matched with U.S. exports, I find that higher inflation volatility is associated with a significantly lower ratio of multinational production to total foreign sales.

Are Recoveries from Banking and Financial Crises Really So Different?

Abstract:

This paper studies the behavior of recoveries from recessions across 59 advanced and emerging market economies over the past 40 years. Focusing specifically on the performance of output after the recession trough, we find little or no difference in the pace of output growth across types of recessions. In particular, banking and financial crisis do not affect the strength of the economic rebound, although these recessions are more severe, implying a sizable output loss. However, recovery does change with some characteristics of recession. Recoveries tend to be faster following deeper recessions, especially in emerging markets, and tend to be slower following long recessions. Most recessions are associated with a slowing, if not outright decline in house prices, but recessions with large declines in house prices also tend to have slower recoveries. Long recessions and those associated with poor housing-market outcomes can lead to sustained output losses relative to pre-crisis trends. Consistent with microeconomic studies showing permanent income loss to job-losing workers during recessions, we find that the sustained deviation in output from trend is associated with a reduction in labor input, especially linked to declines in employment and labor-force participation following recessions. On net, our results imply that the output/employment gap following a severe, long recessions is considerably smaller than is typically assumed by standard macro models, which in turn may have substantial implications for macroeconomic policy during recoveries.

Monetary Regime Switches and Unstable Objectives

Davide Debortoli and Ricardo Nunes

Abstract:

Monetary policy objectives and targets are not necessarily stable over time. The regime switching literature has typically analyzed and interpreted changes in policymakers' behavior through simple interest rate rules. This paper analyzes policy regime switches explicitly modeling policymakers' behavior and objectives. We show how current monetary policy is affected and should optimally respond to alternative regimes. We also show that changes in the parameters of simple rules do not necessarily correspond to changes in policymakers' preferences. In fact, capturing and interpreting regime changes in preferences through interest rate rules can lead to misleading results.

The Variance Risk Premium Around the World

Abstract:

This paper investigates the variance risk premium in an international setting. First, I provide new evidence on the basic stylized facts traditionally documented for the US. I show that while the variance premiums in several other countries are, on average, positive and display significant time variation, they do not predict local equity returns. Then, I extend the domestic model in Bollerslev, Tauchen and Zhou (2009) to an international setting. In light of the qualitative implications of my model, I provide empirical evidence that the US variance premium outperforms that of all other countries in predicting local and foreign equity returns.

Loose Commitment in Medium-Scale Macroeconomic Models: Theory and Applications

Davide Debortoli, Junior Maih, and Ricardo Nunes

Abstract:

This paper proposes a method and a toolkit for solving optimal policy with imperfect commitment. As opposed to the existing literature, our method can be employed in medium- and large-scale models typically used in monetary policy. We apply our method to the Smets and Wouters (2007) model, where we show that imperfect commitment has relevant implications for interest rate setting, the sources of business cycle fluctuations, and welfare.

The Growth of Chinese Exports: An Examination of the Detailed Trade Data

Abstract:

Over the past decade, Chinese exports have boomed, increasing far faster than GDP growth. What can account for this explosion? Our paper uses finely detailed Chinese export data (8-digit HS codes) combined with U.S. trade data to explore this question. Although exchange rate policy clearly boosted the trade surplus, and the structure of the economy, e.g. abundant cheap labor, encouraged investment, these alone cannot account for the changing composition and acceleration of exports. We find that the growth in exports is most likely a product of effective Chinese industrial policy and fortuitous timing. The detailed trade data reveal that key “new” technology goods, such as cell phones, LCD screens, and laptops played a critical role. Finally, we use the data to examine the relationship between Chinese exports and global manufacturing, in particular U.S. manufacturing employment. We find that increased Chinese competition in both domestic and U.S. export markets likely lowered U.S. manufacturing employment between 2000 and 2007. Chinese policy is not, however, wholly responsible. Some job losses, such as in textile production, were no doubt the result of China’s natural comparative advantages, while other U.S. job losses are attributable to relatively low investment and slow GDP growth in the United States following the 2001 recession.

Housing and Debt Over the Life Cycle and Over the Business Cycle

Matteo Iacoviello and Marina Pavan

Abstract:

We study housing and debt in a quantitative general equilibrium model. In the cross-section, the model matches the wealth distribution, the age pro.les of homeownership and mortgage debt, and the frequency of housing adjustment. In the time-series, the model matches the procyclicality and volatility of housing investment, and the procyclicality of mortgage debt. We use the model to conduct two experiments. First, we investigate the consequences of higher individual income risk and lower downpayments, and .nd that these two changes can explain, in the model and in the data, the reduced volatility of housing investment, the reduced procyclicality of mortgage debt, and a small fraction of the reduced volatility of GDP. Second, we use the model to look at the behavior of housing investment and mortgage debt in an experiment that mimics the Great Recession: we find that countercyclical financial conditions can account for large drops in housing activity and mortgage debt when the economy is hit by large negative shocks.

Oil Efficiency, Demand, and Prices: A Tale of Ups and Downs

Martin Bodenstein and Luca Guerrieri

Abstract:

The macroeconomic implications of oil price fluctuations vary according to their sources. Our estimated two-country DSGE model distinguishes between country-specific oil supply shocks, various domestic and foreign activity shocks, and oil efficiency shocks. Changes in foreign oil efficiency, modeled as factor-augmenting technology, were the key driver of fluctuations in oil prices between 1984 and 2008, but have modest effects on U.S. activity. A pickup in foreign activity played an important role in the 2003-2008 oil price runup. Beyond quantifying the responses of oil prices and economic activity, our model informs about the propagation mechanisms. We find evidence that nonoil trade linkages are an important transmission channel for shocks that affect oil prices. Conversely, nominal rigidities and monetary policy are not.

Empirical Estimation of Trend and Cyclical Export Elasticities

Abstract:

This paper uses an adaptation of Vahid and Engle's common trend/common cycle analysis to estimate trend and cyclical export elasticities for trading partner income and real exchange rates for 36 countries. For the countries for which both types of income elasticities can be identified, the cyclical elasticity is on average more than twice as large as the trend elasticity. The methodology is applied to forecasting exports during the recent cycle and it appears to improve on simpler models for about half of the countries. For an aggregate of all of the countries for which separate elasticities can be identified, the RMSE is about half as large for the trend/cycle model as for the simple model.

Firm Default and Aggregate Fluctuations

Tor Jacobson, Jesper Lindé, and Kasper Roszbach

Abstract:

This paper studies the relationship between macroeconomic fluctuations and corporate defaults while conditioning on industry affiliation and an extensive set of firm-specific factors. By using a panel data set for virtually all incorporated Swedish businesses over 1990-2009, a period which includes a full-scale banking crisis, we find strong evidence for a substantial and stable impact from aggregate fluctuations on business defaults. A standard logit model with financial ratios augmented with macroeconomic factors can account surprisingly well for the outburst in business defaults during the banking crisis, as well as the subsequent fluctuations in default frequencies. Moreover, the effects of macroeconomic variables differ across industries in an economically intuitive way. Out-of-sample evaluations show that our approach is superior to models that exclude macro information and standard well-fitting time-series models. Our analysis shows that firm-specific factors are useful in ranking firms' relative riskiness, but that macroeconomic factors are necessary to understand fluctuations in the absolute risk level.

ABS Inflows to the United States and the Global Financial Crisis

Abstract:

The "global saving glut" (GSG) hypothesis argues that the surge in capital inflows from emerging market economies to the United States led to significant declines in long-term interest rates in the United States and other industrial economies. In turn, these lower interest rates, when combined with both innovations and deficiencies of the U.S. credit market, are believed to have contributed to the U.S. housing bubble and to the buildup in financial vulnerabilities that led to the financial crisis. Because the GSG countries for the most part restricted their U.S. purchases to Treasuries and Agency debt, their provision of savings to ultimately risky subprime mortgage borrowers was necessarily indirect, pushing down yields on safe assets and increasing the appetite for alternative investments on the part of other investors. We present a more complete picture of how capital flows contributed to the crisis, drawing attention to the sizable inflows from European investors into U.S. private-label asset-backed securities (ABS), including mortgage-backed securities and other structured investment products. By adding to domestic demand for private-label ABS, substantial foreign acquisitions of these securities contributed to the decline in their spreads over Treasury yields. Through a combination of empirical estimation and model simulation, we verify that both GSG inflows into Treasuries and Agencies, as well as European acquisitions of ABS, played a role in contributing to downward pressures on U.S. interest rates.

Housing Wealth and Consumption

Abstract:

Housing wealth is about one half of household net worth, and consumption is a considerable fraction (about two thirds) of Gross Domestic Product in the United States. Empirically, movements in housing wealth are associated with movements in consumption in the same direction. This observation has led many economists, commentators and policy makers to study how housing wealth and consumption are linked together. A sizeable portion of the comovement between housing wealth and consumption reflects common factors driving both variables, rather than the "wealth effect" of the former on the latter; however, a growing body of evidence suggests that the comovement is larger in developed financial markets and in the presence of liquidity constraints.

The Revealed Competitiveness of U.S. Exports

Massimo Del Gatto, Filippo de Mauro, Joseph Gruber, and Benjamin R. Mandel

Abstract:

The U.S. share of world merchandise exports has declined sharply over the last decade. Using data at the level of detailed industries, this paper analyzes the decline in U.S. share against the backdrop of alternative measures of the competitiveness of the U.S. economy. We document the following facts: (i) only a few industries contributed to the decline in any meaningful way, (ii) a large part of the drop was driven by the changing size of U.S. export industries and not the size of U.S. sales within those industries, (iii) in a gravity framework, the majority of the decline in the U.S. export share within industries was due to the declining U.S. share of world income, and (iv) in a computed structural measure of firm productivity, average U.S. export productivity has generally maintained its high level versus other countries over time. Overall, our analysis suggests that the dismal performance of the U.S. market share is not a sufficient statistic for competitiveness.

Evaluating the Forecasting Performance of Commodity Futures Prices

Abstract:

Commodity futures prices are frequently criticized as being uninformative for forecasting purposes because (1) they seem to do no better than a random walk or an extrapolation of recent trends and (2) futures prices for commodities often trace out a relatively flat trajectory even though global demand is steadily increasing. In this paper, we attempt to shed light on these concerns by discussing the theoretical relationship between spot and futures prices for commodities and by evaluating the empirical forecasting performance of futures prices relative to some alternative benchmarks. The key results of our analysis are that futures prices have generally outperformed a random walk forecast, but not by a large margin, while both futures and a random walk noticeably outperform a simple extrapolation of recent trends (a random walk with drift). Importantly, however, futures prices, on average, outperform a random walk by a considerable margin when there is a sizeable difference between spot and futures prices.

U.S. Domestic and International Financial Reform Policy: Are G20 Commitments and the Dodd-Frank Act in Sync?

Daniel E. Nolle

Abstract:

The Dodd-Frank Act of 2010 is the keystone policy response directed at reforming U.S. financial system activities and oversight in the wake of the 2007-2009 financial crisis. The United States also has financial system reform policy commitments in the international arena, including in particular by virtue of its membership in the G20. This analysis considers U.S. policy initiatives related to a core dimension of financial system reform: risks posed by systemically important financial institutions ("SIFIs"). It provides a comparison of SIFI policy initiatives and timetables under both the Dodd-Frank Act and the G20 agenda, as reflected in the ongoing work plan of the Financial Stability Board (FSB), and poses the question "Are U.S. domestic and international financial system reform commitments in sync?" While finding that, fundamentally, the answer is "yes," the detailed comparison yields two caveats with potential policy implications. First, the two agendas differ in their relative emphasis on the coverage of both banks and nonbanks. The G20/FSB focus, at least over the near-term, is bank-centric compared with the Dodd-Frank Act, which consistently addresses both bank and nonbank financial firms. Second, implementation of Dodd-Frank Act provisions is subject to long-established U.S. law mandating that there be sufficient opportunity for public input into the rulemaking process, whereas the G20/FSB process has been less systematic and transparent on public consultation and feedback. The lesser emphasis on transparency and public input characterizing the G20/FSB policy development process may be attributable in part to the somewhat more rapid pace of the G20/FSB agenda relative to corresponding Dodd-Frank Act timelines. These observations may be relevant to the current debate over the speed and scope of Dodd-Frank Act implementation measures, and to the discussion about the future international competitiveness of U.S. banks and nonbank financial firms.

Optimal Monetary Policy in an Operational Medium-Sized DSGE Model

Malin Adolfson, Stefan Laséen, Jesper Lindé, and Lars E.O. Svensson

Abstract:

We show how to construct optimal policy projections in Ramses, the Riksbank's open-economy medium-sized DSGE model for forecasting and policy analysis. Bayesian estimation of the parameters of the model indicates that they are relatively invariant to alternative policy assumptions and supports our view that the model parameters may be regarded as unaffected by the monetary policy specification. We discuss how monetary policy, and in particular the choice of output gap measure, affects the transmission of shocks. Finally, we use the model to assess the recent Great Recession in the world economy and how its impact on the economic development in Sweden depends on the conduct of monetary policy. This provides an illustration on how Rames incoporates large international spillover effects.

Forecasting the Price of Oil

Ron Alquist, Lutz Kilian, and Robert J. Vigfusson

Abstract:

We address some of the key questions that arise in forecasting the price of crude oil. What do applied forecasters need to know about the choice of sample period and about the tradeoffs between alternative oil price series and model specifications? Are real or nominal oil prices predictable based on macroeconomic aggregates? Does this predictability translate into gains in out-of-sample forecast accuracy compared with conventional no-change forecasts? How useful are oil futures markets in forecasting the price of oil? How useful are survey forecasts? How does one evaluate the sensitivity of a baseline oil price forecast to alternative assumptions about future demand and supply conditions? How does one quantify risks associated with oil price forecasts? Can joint forecasts of the price of oil and of U.S. real GDP growth be improved upon by allowing for asymmetries?

Liquidity and Reserve Requirements in Brazil

Abstract:

The international reform initiative that followed the global financial crisis of 2008-09 has resulted in the introduction of liquidity requirements for banks. Under one requirement, the Liquidity Coverage Ratio (LCR), banks will need to hold enough highly liquid assets to survive for a month in a stress scenario. Banks' required reserve balances can be used to fulfill this liquidity requirement and this may be seen as an attractive option for emerging market economies, where financial sectors are often underdeveloped. In this paper, I examine the Brazilian experience prior to and during the global crisis as a case study that can shed light into the challenges of using reserve requirements as a liquidity management tool. Brazilian reserve requirements did not ensure adequate liquidity, in part because the smallest banks were exempted from the requirements. Financial innovations were also used by banks to circumvent reserve requirements. In Brazil, the use of reserve requirements as a liquidity management tool is often justified by the argument that reserve requirements fulfilled a critical liquidity provision role in the fall of 2008. I argue that Brazilian reserve requirements did not actually serve well the liquidity provision goal.

Financial Frictions, Trade Credit, and the 2008-09 Global Financial Crisis

Abstract:

This paper studies the role of the credit crunch in the severe contraction of economic activity during the 2008-09 global financial crisis, using firm-level data from six emerging Asian economies. After controlling for the effect of falling demand, we find that sales declined by less for firms with better pre-crisis financial conditions. Amid the decline in external financing opportunities, some firms relied more on trade credit from suppliers during the crisis, which allowed them to post relatively better sales. Export-intensive firms resorted less to trade credit as an alternative source of finance, which contributed to their larger declines in sales.

Limited Market Participation and Asset Prices in the Presence of Earnings Management

Bo Sun

Abstract:

We examine the role of earnings management in explaining the properties of asset prices and stock market participation. We demonstrate that investors' uncertainty about the extent of manipulation can cause excess movements in stock price relative to fluctuations in output. When faced with information asymmetry about fundamentals in the presence of earnings management, investors demand a higher equity premium for bearing the additional risk associated with their payoffs. In addition, when investors have heterogeneous beliefs about managerial manipulation, the dispersion in belief endogenously gives rise to limited stock market participation. Our model suggests that the increasing stringency of corporate governance and varying composition of investors may have played a role in the contemporaneous run-up of market participation rates in the recent years.

Quantitative Easing and Bank Lending: Evidence from Japan

Abstract:

Prior to the recent financial crisis, one of the most prominent examples of unconventional monetary stimulus was Japan's "quantitative easing policy" (QEP). Most analysts agree that QEP did not succeed in stimulating aggregate demand sufficiently to overcome persistent deflation. However, it remains unclear whether QEP simply provided little stimulus, or whether its positive effects were overwhelmed by the contractionary forces in Japan's post-bubble economy. In the spirit of Kashyap and Stein (2000) and Hosono (2006), this paper uses bank-level data from 2000 to 2009 to examine the effectiveness in promoting bank lending of a key element of QEP, the Bank of Japan's injections of liquidity into the interbank market. We identify a robust, positive, and statistically significant effect of bank liquidity positions on lending, suggesting that the expansion of reserves associated with QEP likely boosted the flow of credit. However, the overall size of that boost was probably quite small. First, the estimated response of lending to liquidity positions in our regressions is small. Second, much of the effect of the BOJ's reserve injections on bank liquidity was offset as banks reduced their lending to each other. Finally, the effect of liquidity on lending appears to have held only during the initial years of QEP, when the banking system was at its weakest; by 2005, even before QEP was abandoned, the relationship between liquidity and lending had evaporated.

Where are Global and U.S. Trade Heading in the Aftermath of the Trade Collapse: Issues and Alternative Scenarios

Joseph W. Gruber, Filippo di Mauro, Bernd Schnatz, and Nico Zorell

Abstract:

Global and U.S. trade declined dramatically in the wake of the global financial crisis in late 2008 and early 2009. The subsequent recovery in trade, while vigorous at first, gradually lost momentum in 2010. Against this backdrop, this paper explores the prospects for global and U.S. trade in the medium term. We develop a unified empirical framework – an error correction model – that exploits the cointegrating relationship between trade and economic activity. The model allows us to juxtapose several scenarios with different assumptions about the strength of GDP growth going forward and the relationship between trade and economic activity. Our analysis suggests that during the crisis both world trade and U.S. exports declined significantly more than would have been expected on the basis of historical relationships with economic activity. Moreover, this gap between actual and equilibrium trade is closing only slowly and could persist for some time to come.

U.S. International Equity Investment and Past Prospective Returns

Stephanie E. Curcuru, Charles P. Thomas, Francis E. Warnock, and Jon Wongswan

Abstract:

Counter to extant stylized facts, using newly available data on country allocations in U.S. investors' foreign equity portfolios we find that (i) U.S. investors do not exhibit returns-chasing behavior, but, consistent with partial portfolio rebalancing, tend to sell past winners; and (ii) U.S. investors increase portfolio weights on a country's equity market just prior to its strong performance, behavior inconsistent with an informational disadvantage. Over the past two decades, U.S. investors' foreign equity portfolios outperformed a value-weighted foreign benchmark by 160 basis points per year.

Explaining the Energy Consumption Portfolio in a Cross-Section of Countries: Are the BRICs Different?

Abstract:

This paper uses disaggregated data from a broad cross-section of countries to empirically assess differences in energy consumption profiles across countries. We find empirical support for the energy ladder hypothesis, which contends that as an economy develops it transits away from a heavier reliance on traditional fuel sources towards an increase in the use of modern commercial energy sources. We also find empirical support for the hypothesis that structural transformation--the idea that as an economy matures, it transforms away from agriculture-based activity into industrial activity and, finally, fully matures into a service-oriented economy--is an important driver for the distribution of end-use energy consumption. However, even when these two hypotheses are taken into account, we continue to find evidence suggesting that the patterns of energy consumption in the BRIC economies are importantly different from those of other economies.

International Capital Flows and the Returns to Safe Assets in the United States, 2003-2007

Abstract:

A broad array of domestic institutional factors--including problems with the originate-to-distribute model for mortgage loans, deteriorating lending standards, deficiencies in risk management, conflicting incentives for the GSEs, and shortcomings of supervision and regulation--were the primary sources of the U.S. housing boom and bust and the associated financial crisis. In addition, the extended rise in U.S. house prices was likely also supported by long-term interest rates (including mortgage rates) that were surprisingly low, given the level of short-term rates and other macro fundamentals--a development that Greenspan (2005) dubbed a "conundrum." The "global saving glut" (GSG) hypothesis (Bernanke, 2005 and 2007) argues that increased capital inflows to the United States from countries in which desired saving greatly exceeded desired investment--including Asian emerging markets and commodity exporters--were an important reason that U.S. longer-term interest rates during this period were lower than expected.

This essay investigates further the effects of capital inflows to the United States on U.S. longer-term interest rates; however, we look beyond the overall size of the inflows emphasized by the GSG hypothesis to examine the implications for U.S. yields of the portfolio preferences of foreign creditors. We present evidence that, in the spirit of Caballero and Krishnamurthy (2009), foreign investors during this period tended to prefer U.S. assets perceived to be safe. In particular, foreign investors--especially the GSG countries--acquired a substantial share of the new issues of U.S. Treasuries, Agency debt, and Agency-sponsored mortgage-backed securities. The downward pressure on yields exerted by inflows from the GSG countries was reinforced by the portfolio preferences of other foreign investors. We focus particularly on the case of Europe: Although Europe did not run a large current account surplus as did the GSG countries, we show that it leveraged up its international balance sheet, issuing external liabilities to finance substantial purchases of apparently safe U.S. "private-label" mortgage-backed securities and other fixed-income products. The strong demand for apparently safe assets by both domestic and foreign investors not only served to reduce yields on these assets but also provided additional incentives for the U.S. financial services industry to develop structured investment products that "transformed" risky loans into highly-rated securities.

Our findings do not challenge the view that domestic factors, including those listed above, were the primary sources of the housing boom and bust in the United States. However, examining how changes in the pattern of international capital flows affected yields on U.S. assets helps provide a deeper understanding of the origins and dynamics of the crisis.

Nonlinearities in the Oil Price-Output Relationship

Lutz Kilian and Robert J. Vigfusson

Abstract:

It is customary to suggest that the asymmetry in the transmission of oil price shocks to real output is well established. Much of the empirical work cited as being in support of asymmetries, however, has not directly tested the hypothesis of an asymmetric transmission of oil price innovations. Moreover, many of the papers quantifying these asymmetric responses are based on censored oil price VAR models which recently have been shown to be invalid. Other studies are based on dynamic correlations in the data that do not shed light on the central question of whether the structural responses of real output triggered by positive and negative oil price innovations are asymmetric. Recently, a number of new methodologies have been introduced and applied to the problem of testing and quantifying asymmetric responses of U.S. real economic activity to positive and negative oil price innovations. Our objective is to put this literature in perspective, to contrast it with more traditional approaches, to highlight directions for further research, and to reconcile some seemingly conflicting results reported in the literature.
