Monetary policy affects the tradeoffs faced by governments in sovereign default models. In the absence of lump-sum taxation, governments rely on both disortionary taxes and seigniorage to finance expenditure. Furthermore, monetary policy adds a time-consistency problem in debt choice, which may mitigate or exacerbate the incentives to accumulate debt. A deterioration of the terms-of-trade leads to an increase in sovereign-default risk and inflation, and a reduction in growth, which are consistent with the empirical evidence for emerging economies. An unanticipated shock resembling the COVID-19 pandemic generates a significant currency depreciation, increased inflation, and distress in government finances.
This article describes the origins and development of the federal funds market from its inception in the 1920s to the early 1950s. We present a newly digitized daily data series on the federal funds rate that covers the period from April 1928 through June 1954. We compare the behavior of the funds rate with other money market interest rates and the Federal Reserve discount rate. Our federal funds rate series will enhance the ability of researchers to study an eventful period in U.S. financial history and to better understand how monetary policy was transmitted to banking and financial markets. For the 1920s and 1930s, our series is the best available measure of the overnight risk-free interest rate, better than the call money rate which many studies have used for that purpose. For the 1940s-1950s, our series provides new information about the transition away from wartime interest-rate pegs culminating in the 1951 Treasury-Federal Reserve Accord.
This paper takes a unique approach to the scenario where a resident terrorist group in a (fragile) developing nation poses a terrorism threat at home and abroad. The host developing nation’s proactive countermeasures against the resident terrorist group not only limits terrorism at home and abroad, but also bolsters regime stability at home. A two-stage game is presented in which the developed country takes a leadership role to institute a tax-subsidy combination to discourage (encourage) proactive measures at home (abroad) in stage 1. Stage 2 involves both nations’ counterterrorism choices under alternative stage-1 public-policy packages. Unlike the extant literature, we explore corner and interior solutions in both stages based on the terrorists’ targeting preferences and the host nation’s regime-stability preferences. Surprisingly, the developed nation may profit from policy packages that reduce global counterterrorism while raising global terrorism. This outcome and others involve engineered counterterrorism burden shifting.
This paper decomposes the causal effect of government defense spending into: (i) a local (or direct) effect, and (ii) a spillover (or indirect) effect. Using state-level defense spending data, we show that a negative cross-state spillover effect explains the existing simultaneous findings of a low aggregate multiplier and a high local multiplier. We show that enlisting disaggregate data improves the precision of aggregate effect estimates, relative to using aggregate time series alone. Moreover, we compare two-step efficient GMM with two alternative moment weighting approaches used in existing research.
I present a model where work implies social interactions and the spread of a disease is described by an SIR-type framework where both susceptible and infectious are asymptomatic. Upon the outbreak of a disease a lower contact rate can be achieved at the cost of lower consumption. Individuals do not internalize the effects of their decisions on the evolution of the epidemic while the planner does. Specifically, the planner internalizes that a low contact rate early in the epidemic implies a low stock of infectious in the future; and a low stock of infectious in the future permits an increase in the contact rate without risking additional infections. Since a low contact rate is associated with low consumption, the planner effectively substitutes consumption early in the epidemic for consumption later. The individual's response does not, hence the planner obtains a flatter infection curve than that generated by the individual's' response, even though the planner's objective is not to ``flatten the curve.''
Short-term debt is commonly used to fund illiquid assets. A conventional view asserts that such arrangements are run-prone in part because redemptions must be processed on a first-come, first-served basis. This sequential service protocol, however, appears absent in the wholesale banking sector---and yet, shadow banks appear vulnerable to runs. We explain how banking arrangements that fund fixed-cost operations using short-term debt can be run-prone even in the absence of sequential service. Interventions designed to eliminate run risk may or may not improve depositor welfare. We describe how optimal policies vary under different conditions and compare these to recent policy interventions by the Security and Exchange Commission and the Federal Reserve. We conclude that the conventional view concerning the societal benefits of liquidity transformation and its recommendations for prudential policy extend far beyond their application to depository institutions.
We measure labor demand and supply shocks at the sector level around the COVID-19 outbreak by estimating a Bayesian structural vector autoregression on monthly statistics of hours worked and real wages. Most sectors were subject to historically large negative labor supply and demand shocks in March and April, with substantial heterogeneity in the size of shocks across sectors. Our estimates suggest that two-thirds of the drop in the aggregate growth rate of hours in March and April 2020 are attributable to labor supply. We validate our estimates of supply shocks by showing that they are correlated with sectoral measures of telework.
This paper studies the role of international trade of essential goods during a pandemic. We consider a multi-country, multi-sector model with essential and non-essential goods. Essential goods provide utility relative to a reference consumption level, and a pandemic consists of an increase in this reference level. Each country produces domestic varieties of both types of goods using capital and labor subject to sectoral adjustment costs, and all varieties are traded internationally subject to trade barriers. We study the role of international trade of essential goods in mitigating or amplifying the impact of a pandemic. We find that the effects depend crucially on the countries' trade imbalances in essential goods. Net importers of these goods are relatively worse off during a pandemic than net exporters. The welfare losses of net importers are lower in a world with high trade barriers, while the reverse is the case for net exporters. Yet, once a pandemic arrives, net exporters of essential goods benefit from an increase in trade barriers, while net importers benefit from a decrease in them. These findings are consistent with preliminary evidence on changes in trade barriers across countries during the COVID-19 pandemic.
The largest economic cost of the COVID-19 pandemic could arise if it changed behavior long after the immediate health crisis is resolved. A common explanation for such a long-lived effect is the scarring of beliefs. We show how to quantify the extent of such belief changes and determine their impact on future economic outcomes. We find that the long-run effect of the COVID crisis depends crucially on whether bankruptcies and changes in habit make existing capital obsolete. A policy that avoided most permanent separation of workers from capital could generate a much larger benefit than originally thought, that could easily be 180% of annual GDP, in present value.
This paper studies the optimal maturity structure for government debt when markets for liquidity insurance are incomplete or non-competitive. There is no fiscal risk. Government debt in the model solves a dynamic inefficiency. Issuing debt in short and long maturities solves a liquidity insurance problem, but optimal yield curve policy is only possible if long-duration debt is rendered illiquid. Optimal policy is implementable through treasury operations only--adjustments in the primary deficit are not necessary.
The rapidly growing national debt in the U.S. since the 1970s has alarmed and intrigued the academic world. Consequently, the concept of dynamic (in)efficiency in an overlapping generations (OLG) world and the importance of the heterogeneous-agents and incomplete markets (HAIM) hypothesis to justify a high debt-to-GDP ratio have been extensively studied. Two important consensus emerge from this literature: (i) The optimal quantity of public debt is positive—due to insufficient private liquidity to support private saving and investment (see, e.g., Barro (1974), Woodford (1990), and Aiyagari and McGrattan (1998)); (ii) the optimal capital tax is positive—because of precautionary saving and the consequent failure of the modified golden rule (see, e.g., Aiyagari (1995)). But these two consensus views are seldom derived jointly in the same model, so the dynamic relationship between optimal debt and optimal taxation remains unclear in HAIM models, especially considering that the optimal quantity of debt must be judged by the golden-rule saving rate and any debt must be financed by future taxes. We use a primal Ramsey approach to analytically characterize optimal debt and tax policy in an OLG-HAIM model. We show that since precautionary saving and oversaving are not necessarily the same thing, they have different policy implications—the Ramsey planner opts to issue bonds to crowd out private savings if and only if a competitive equilibrium is dynamically inefficient regardless of precautionary savings. In other words, optimal debt can be negative even if households cannot insure themselves against idiosyncratic risk under borrowing constraints. The sign and magnitude of the optimal quantity of debt in turn dictate the sign and magnitude of optimal taxes as well as the priority order of tax tools such as a labor tax vs. a capital tax.
I study the effects of the 2019-20 coronavirus outbreak in the United States and subsequent fiscal policy response in a nonlinear DSGE model. The pandemic is a shock to the utility of contact-intensive services that propagates to other sectors via general equilibrium, triggering a deep recession. I use a calibrated version of the model to analyze different types of fiscal policies. I find that UI benefits are the most effective tool to stabilize income for borrowers, who are the hardest hit, while savers may favor unconditional transfers. Liquidity assistance programs are effective if the policy objective is to stabilize employment in the affected sector. I also study the effects of the $2 trillion CARES Act of 2020.
In this paper we present and describe a large quarterly frequency, macroeconomic database. The data provided are closely modeled to that used in Stock and Watson (2012a). As in our previous work on FRED-MD, our goal is simply to provide a publicly available source of macroeconomic “big data” that is updated in real time using the FRED database. We show that factors extracted from this data set exhibit similar behavior to those extracted from the original Stock and Watson data set. The dominant factors are shown to be insensitive to outliers, but outliers do affect the relative influence of the series as indicated by leverage scores. We then investigate the role unit root tests play in the choice of transformation codes with an emphasis on identifying instances in which the unit root-based codes differ from those already used in the literature. Finally, we show that factors extracted from our data set are useful for forecasting a range of macroeconomic series and that the choice of transformation codes can contribute substantially to the accuracy of these forecasts.
New vehicle sales in the U.S. fell nearly 40 percent during the past recession, causing significant job losses and unprecedented government interventions in the auto industry. This paper explores three potential explanations for this decline: increasing oil prices, falling home values, and falling household income expectations. First, we use the historical macroeconomic relationship between oil prices and vehicle sales to show that the oil price spike explains roughly 15 percent of the auto sales decline between 2007 and 2009. Second, we establish that declining home values explain only a small portion of the observed reduction in household new vehicle sales. Using a county-level panel from the episode, we find (1) a one-dollar fall in home values reduced household new vehicle spending by 0.5 to 0.7 cents and overall new vehicle spending by 0.9 to 1.2 cents and (2) falling home values explain between 16 and 19 percent of the overall new vehicle spending decline. Next, examining state-level data for 1997-2016, we find (3) the short-run responses of new vehicle consumption to home value changes are larger in the 2005-2011 period relative to other years, but at longer horizons (e.g. 5 years), the responses are similar across the two sub-periods and (4) the service flow from vehicles, as measured by miles traveled, responds very little to house price shocks. We also detail the sources of the differences between our findings (1) and (2) from existing research. Third, we establish that declining current and expected future income expectations potentially played an important role in the auto market's collapse. We build a permanent income model augmented to include infrequent repeated car buying. Our calibrated model matches the pre-recession distribution of auto vintages and the liquid-wealth-to-income ratio, and exhibits a large vehicle sales decline in response to a mild decline in expected permanent income due to a transitory slowdown in income growth. In response to the shock, households delay replacing existing vehicles, allowing them to smooth the effects of the income shock without significantly adjusting the service flow from their vehicles. Augmenting our model with a richer set of household expectations allows us to match 65 percent of the overall new vehicle spending decline (i.e. roughly the portion of the decline not explained by oil prices and falling home values). Combining our negative results regarding housing wealth and oil prices with our positive model-based findings, we interpret the auto market collapse as consistent with existing permanent income based approaches to durable goods purchases (e.g., Leahy and Zeira (2005)).
Deciding to undertake a series of tightening actions present unique challenges for Federal Reserve policymakers. These challenges are both political and economic. Using a variety of economic and financial market metrics, this article examines how the economy and financial markets evolved in response to the five tightening episodes enacted by the FOMC since 1983. The primary aim is to compare the most-recent episode, from December 2015 to December 2018, with the previous four episodes. The findings in this article indicate that the current episode bears some resemblance to previous Fed tightening episodes, but also differs in several key dimensions. For example, in the first four episodes, the data show the FOMC was generally tightening into a strengthening economy with building price pressures. In contrast, in the fifth episode the FOMC began its tightening regime during a deceleration in economic activity and with headline and core inflation remaining well below the FOMC’s 2 percent inflation target. Moreover, both short- and long-term inflation expectations were drifting lower. These developments helped explain why there was a one-year gap between the first and second increases in the federal funds target rate in the most-recent episode. Another key difference is that in three of the first four episodes, the FOMC continued to tighten after the yield curve inverted; a recession then followed shortly thereafter. However, in the final episode, the FOMC ended its tightening policy about eight months before the yield curve inverted. It remains to be seen if a recession follows this inversion.
The aggregate capital stock in a nation can be overaccumulated for many different reasons. This paper studies which policy or policy mix is more effective in achieving the socially optimal (golden rule) level of aggregate capital stock in an infinite-horizon heterogeneous-agents incomplete-markets economy where capital is over-accumulated for two distinct reasons: (i) precautionary savings and (ii) production externalities. By solving the Ramsey problem analytically along the entire transitional path, we show that public debt and capital taxation play very distinct roles in dealing with the overaccumulation problem. The Ramsey planner opts neither to use a capital tax to correct the overaccumulation problem if it is caused solely by precautionary saving---regardless of the feasibility of public debt---nor use debt (financed by consumption tax) to correct the overaccumulation problem if it is caused solely by pollution---regardless of the feasibility of a capital tax. The key is that the modified golden rule has two margins: an intratemporal margin pertaining to the marginal product of capital (MPK) and an intertemporal margin pertaining to the time discount rate. To achieve the MGR, the Ramsey planner needs to equate not only the private MPK with the social MPK but also the interest rate with the time discount rate---neither of which is equalized in a competitive equilibrium. Yet public debt and a capital tax are each effective only in calibrating one of the two margins, respectively, but not both.
The closing of a busy airport has large effects on noise and economic activity. Using a unique dataset, we examine the effects of closing Denver’s Stapleton Airport on nearby housing markets. We find evidence of immediate anticipatory price effects upon announcement, but no price changes at closing likely because closing was widely anticipated. Further, after airport closure, high income and white households moved into these locations and developers upgraded the quality of houses being built. Finally, post-closing, these demographic and housing stock changes had substantial effects on housing prices, even after restricting the sample to pre-existing housing.
We use an analytically tractable model to show that the Ramsey planner's decisions to finance stochastic public expenditures under uninsurable idiosyncratic risk implies a departure from tax smoothing. In the absence of state-contingent bonds the government's attempt to balance the competing incentives between tax smoothing and individual consumption smoothing---even at the cost of extra tax distortion---implies a bounded stochastic unit root component in optimal taxes. Nonetheless, a sufficiently high average level of public debt to support individuals’ self-insurance position is welfare improving, consistent with the strictly positive quantity of government debt observed throughout human history.
US payroll employment data come from a survey of nonfarm business establishments and are
therefore subject to revisions. While the revisions are generally small at the national level, they can be
large enough at the state level to substantially alter assessments of current economic conditions.
Researchers and policymakers must therefore exercise caution in interpreting state employment data
until they are “benchmarked” against administrative data on the universe of workers some 5 to 16
months after the reference period. This paper develops and tests a state space model that predicts
benchmarked US state employment data in realtime. The model has two distinct features: 1) an explicit
model of the data revision process and 2) a dynamic factor model that incorporates realtime
information from other state-level labor market indicators. We find that across the 50 US states, the
model reduces the average size of benchmark revisions by about 9 percent. When we optimally
average the model’s predictions with those of existing models, we find that we can reduce the average
size of the revisions by about 15 percent.
The wave of sovereign defaults in the early 1980s and the string of debt crises in the decades that followed have fostered proposals involving policy interventions in sovereign debt restructurings. A key question about these proposals that has proved hard to handle is how they in influence the behavior of creditors and debtors. We address such challenge by incorporating these policy proposals into a quantitative model in the tradition of Eaton and Gersovitz (1981) that includes renegotiation in sovereign debt restructurings. Critically, the model also endogenizes the choice of debt maturity, an essential aspect of sovereign defaults and restructurings. We evaluate several policy interventions, and we identify the crucial features that matter to improve the outcome of distressed debt restructurings and reduce the frequency of debt distress events.
Gino Gancia, Giacomo Ponzetto and Jaume Ventura have written an extremely interesting paper on a topic that is very timely for the global economy. In this article, I will first argue that GPV have succeeded in formalizing their hypothesis, and that while providing very suggestive analytical results, additional work can and should be done with the model, especially with regards to relative changes in the relative weights of incumbent countries. Second, I will comment on the potential insights if the rest of the world is modeled more realistically. Third, I will call for extending the baseline model to incorporate additional aspects beyond trade, such as investment and immigration flows, which appear to be relevant for the story of the European Union and its discontents. Four, I will add my non-European perspective on using the model to understand the story of the European Union.
We propose a method to decompose changes in the tax structure into orthogonal components measuring the level and progressivity of taxes. While our focus is on the progessivity results, we find that the level shock is similar to standard tax shocks found in the empirical literature in that a rise in the level is contractionary. We find that an increase in tax progressivity sets off an economic boom. When tax progressivity increases, those at the bottom of the income distribution experience an increase in disposable income; these consumers have a high marginal propensity to consume, and this increase in income results in a consumption boom which expands the overall economy. This overall economic expansion benefits those at the top of the income distribution as well, and the income and capital gains they experience as a result of the economic boom more than offset the losses they experienced due to the increase in tax progressivity. The net result is that an increase in progressivity leads to an increase in inequality, not a decrease as conventional wisdom would suggest. We interpret these results as evidence in favor of trickle up, not trickle down, economics.
The global financial crisis of the past decade has shaken the research and policy worlds out of their belief that housing markets are mostly benign and immaterial for understanding economic cycles. Instead, a growing consensus recognizes the central role that housing plays in shaping economic activity, particularly during large boom and bust episodes. This article discusses the latest research regarding the causes, consequences, and policy implications of housing crises with a broad focus that includes empirical and structural analysis, insights from the 2000's experience in the United States, and perspectives from around the globe. Even with the significant degree of heterogeneity in legal environments, institutions, and economic fundamentals over time and across countries, several common themes emerge to guide current and future thinking in this area.
We propose a tractable framework for monetary policy analysis in which both short- and long-term debt affect equilibrium outcomes. This objective is motivated by observations from two literatures suggesting that monetary policy contains a dimension affecting expected future interest rates and thus the costs of long-term financing. In New-Keynesian models, however, long-term loans are redundant assets. We use the model to address three questions: what are the effects of statement vs. action policy shocks; how important are standard New- Keynesian vs. cash flow effects in their transmission; and what is the interaction between these two effects?
This paper investigates, empirically, the determinants of international technology diffusion. To do that, I set up a multi-country model of innovation and diffusion with perfect enforcement of intellectual property rights (IPR). The model yields a gravity equation for bilateral royalty payments that is estimated using methods from empirical trade. I investigate discrepancies between model’s predictions and observed royalty payments to identify the role of fundamentals vs. other factors such as imperfect IPR protection. Fundamentals account for most of the variation in royalty payments, whereas imperfect IPR protection and other factors are important in accounting for discrepancies between model and data.
The Bretton Woods international financial system, which was in place from roughly 1949 to 1973, is the most significant modern policy experiment to attempt to simultaneously manage international payments, international capital flows, and international currency values. This paper uses an international macroeconomic accounting methodology to study the Bretton Woods system and finds that it: (1) significantly distorted both international and domestic capital markets and hence the accumulation and allocation of capital; (2) significantly slowed the reconstruction of Europe, albeit while limiting the indebtedness of European countries. Our results also provide support for the utility of the accounting methodology in that it finds a sharp change in the behavior of domestic and international capital market wedges that coincides with the breakdown of the system.
While conditional forecasting has become prevalent both in the academic literature and in practice (e.g., bank stress testing, scenario forecasting), its applications typically focus on continuous variables. In this paper, we merge elements from the literature on the construction and implementation of conditional forecasts with the literature on forecasting binary variables. We use the Qual-VAR [Dueker (2005)], whose joint VAR-probit structure allows us to form conditional forecasts of the latent variable which can then be used to form probabilistic forecasts of the binary variable. We apply the model to forecasting recessions in real-time and investigate the role of monetary and oil shocks on the likelihood of two U.S. recessions.
This paper examines house price diffusion across metropolitan areas in the United States. We develop a generalization of the Hamilton and Owyang (2012) Markov-switching model, where we incorporate direct regional spillovers using a spatial weighting matrix. The Markov-switching framework allows consideration for house price movements that occur due to similar timing of downturns across MSAs. The inclusion of the spatial weighting matrix improves fit compared to a standard endogenous clustering model. We find seven clusters of MSAs that experience idiosyncratic recessions plus one distinct national house price cycle. Notably only the housing downturn associated with the Great Recession spread across all of the MSAs in our sample; other house price downturns remained contained to a single cluster. Previous research has found that housing cycles and business cycles are intertwined. To examine this potential relationship we apply our spatial Markov-switching model to employment growth data. We find that house price comovement and employment comovement are distinct across cities.
Countries have widely imposed fiscal rules designed to constrain government spending and ensure fiscal responsibility. This paper studies the effectiveness and welfare implications of revenue, deficit and debt rules when governments are discretionary and profligate. The optimal prescription is a revenue ceiling coupled with a balance budget requirement. For the U.S., the optimal revenue ceiling is about 15% of output, 3 percentage points below the postwar average, and yields welfare gains equivalent to 10% of consumption. Most of the benefits can still be reaped with a milder constraint or escape clauses during adverse times. Imposing a single fiscal rule allows governments to comply without necessarily curbing spending; on their own, revenue ceilings are only mildly effective, while deficit and debt rules are altogether ineffective.
During the Great Recession, the collapse of consumption across the U.S. varied greatly but systematically with house-price declines. We nd that financial distress among U.S. households amplified the sensitivity of consumption to house-price shocks. We uncover two essential facts: (1) the decline in house prices led to an increase in household financial distress prior to the decline in income during the recession, and (2) at the zip-code level, the prevalence of financial distress prior to the recession was positively correlated with house-price declines at the onset of the recession. Using a rich-estimated-dynamic model to measure the financial distress channel, we nd that these two facts amplify the aggregate drop in consumption by 7 percent and 45 percent respectively.
