Lower Bound Uncertainty and Long-Term Interest Rates

Nominal interest rates are constrained by an effective lower bound, but the level of the lower bound is uncertain. This paper uses a simple shadow rate term structure model to study how lower bound uncertainty affects long-term interest rates. A decline in lower bound uncertainty, in the sense of a mean-preserving contraction, is associated with a drop in expected short rates. The effect on the variance of short rates, and hence the term premium, is ambiguous. A calibration to Canadian data suggests that a decline in lower bound uncertainty is associated with a modest drop in interest rates.     

International capital flows and U.S. interest rates

Foreign purchases of U.S. government bonds have an economically large and statistically significant impact on long-term interest rates. While the dramatic reductions in both long-term inflation expectations and the volatility of long rates contributed much to the decline of long rates in the 1990s, more recently foreign flows have become important. Controlling for various factors, we estimate that absent the substantial foreign inflows into U.S. government bonds the 10-year Treasury yield would be 80 basis points higher. Our results are robust to a number of alternative specifications.     

What does a term structure model imply about very long-term interest rates?

We address two empirical issues related to the long end of the yield curve based on euro swap rates. First, for maturities longer than 20 years we find evidence for an ‘excess’ downward slope that cannot be explained by convexity. Second, volatility at the very long end of the yield curve is larger than predicted by no-arbitrage models. We construct a model-based arbitrage-free extrapolation of the yield-curve and compare it to the regulatory discount curve. Because of near-zero mean reversion, there is no convergence towards an ‘ultimate forward rate’ and convexity effects cause the arbitrage-free extrapolations to have slightly downward sloping curves. The low level of mean-reversion also implies that the volatility of long-term rates does not decline relative to the 20-year volatility. Therefore, we conclude that the mean-reversion and resulting smoothing adopted by the regulatory curve is much too strong.     

Global asset prices and FOMC announcements

This paper analyzes the impact of U.S. monetary policy announcement surprises on foreign equity indexes, short- and long-term interest rates, and exchange rates in 49 countries. We use two proxies for monetary policy surprises: the surprise change to the current target federal funds rate (target surprise) and the revision to the expected path of future monetary policy (path surprise). We find that different asset classes respond to different components of the monetary policy surprises. Global equity indexes respond mainly to the target surprise; exchange rates and long-term interest rates respond mainly to the path surprise; and short-term interest rates respond to both surprises. On average, a hypothetical surprise 25-basis-point cut in the federal funds target rate is associated with about a 1 percent increase in foreign equity indexes and a 5 basis point decline in foreign short-term interest rates. A surprise 25-basis-point downward revision in the expected path of future policy is associated with about a ½ percent decline in the exchange value of the dollar against foreign currencies and 5 and 8 basis point declines in short- and long-term interest rates, respectively. We also find that asset prices’ responses to FOMC announcements vary greatly across countries, and that these cross-country variations in the response are related to a country’s exchange rate regime. Equity indexes and interest rates in countries with a less flexible exchange rate regime respond more to U.S. monetary policy surprises. In addition, the cross-country variation in the equity market response is strongly related to the percentage of each country’s equity market capitalization owned by U.S. investors. This result suggests that investors’ asset holdings may play a role in transmitting monetary policy surprises across countries.     

Housing and the labor market: Time to move and aggregate unemployment

Conventional macro-search models (Mortensen and Pissarides) with unemployment benefits and taxes have been able to account for the variation in unemployment rates across countries but do not account for the role geographic mobility or commuting time might play. We build a model in which both unemployment and mobility rates are endogenous. Our findings indicate that an increase in unemployment benefits and in taxes does not generate a strong decline in mobility but does increase unemployment as in the standard model. We find that with higher commuting costs the effect of housing frictions plays a large role and can generate a substantial decline in mobility.     

Mortgage convexity

Most home mortgages in the United States are fixed-rate loans with an embedded prepayment option. When long-term rates decline, the effective duration of mortgage-backed securities (MBS) falls due to heightened refinancing expectations. I show that these changes in MBS duration function as large-scale shocks to the quantity of interest rate risk that must be borne by professional bond investors. I develop a simple model in which the risk tolerance of bond investors is limited in the short run, so these fluctuations in MBS duration generate significant variation in bond risk premia. Specifically, bond risk premia are high when aggregate MBS duration is high. The model offers an explanation for why long-term rates could appear to be excessively sensitive to movements in short rates and explains how changes in MBS duration act as a positive-feedback mechanism that amplifies interest rate volatility. I find strong support for these predictions in the time series of US government bond returns.     

Are U.S. firms using more short-term debt?

We show that, despite the sharp but temporary decline around the financial crisis of 2007–08, corporate debt maturity has risen significantly in the last two decades, erasing much of the secular decline from the 1980–90s documented in the literature. The reversal in debt maturity trend is driven by the rise in the use of intermediate-term debt among medium and large-sized firms. The low interest rates observed in the last two decades and the decline in the demand for long-term corporate bonds partly explains the rise in intermediate-term debt.     

Too much of a good thing? A theory of short-term debt as a sorting device

This paper shows that the liquidity risk associated with short-term debt financing can be used to sort insolvent firms out of financial markets when their solvency risk is private information. Notwithstanding this sorting role of short-term debt, unregulated financial firms tend to choose an inefficiently short debt maturity structure. This inefficiency arises for two reasons. First, by issuing more short-term debt, low-risk firms reduce their expected funding costs. This leads to a misalignment of private and social incentives as firms fail to fully internalize the social costs of becoming illiquid. Second, while the sorting role of short-term debt is reflected in a decline of long-term interest rates when more short-term debt is issued, creditors’ inability to observe firms’ solvency risk leads to an excessive reduction of long-term interest rates. This further distorts firms’ funding choice towards short-term debt.     

Deposit interest rates, asset risk and bank failure in Croatia

Financial deregulation, while beneficial in the long-term, seems to be linked to instability. Intense competition for deposits appears to be an ingredient in instability. We examine the aftermath of deregulation in Croatia, which included rapid growth of both deposits and deposit interest rates, followed by numerous bank failures.

Using panel regression techniques, we find evidence of “market-stealing” via high deposit interest rates. We connect high deposit interest rates to bank failure using logit models. High deposit interest rates were a reliable signal of risk-taking. When supervisory capabilities and powers are weak, deposit interest rate regulation may be worth considering.     

Central bank announcements of asset purchases and the impact on global financial and commodity markets

We present evidence on the effects of large-scale asset purchases by the Federal Reserve and the Bank of England since 2008. We show that announcements about these purchases led to lower long-term interest rates and depreciations of the U.S. dollar and the British pound on announcement days, while commodity prices generally declined despite this more stimulative financial environment. We suggest that LSAP announcements likely involved signaling effects about future growth that led investors to downgrade their U.S. growth forecasts lowering long-term US yields, depreciating the value of the U.S. dollar, and triggering a decline in commodity prices. Moreover, our analysis illustrates the importance of controlling for market expectations when assessing these effects. We find that positive U.S. monetary surprises led to declines in commodity prices, even as long-term interest rates fell and the U.S. dollar depreciated. In contrast, on days of negative U.S. monetary surprises, i.e. when markets evidently believed that monetary policy was less stimulatory than expected, long-term yields, the value of the dollar, and commodity prices all tended to increase.     

Long-term bank balance sheet management: Estimation and simulation of risk-factors

We propose a dynamic framework which encompasses the main risks in balance sheets of banks in an integrated fashion. Our contributions are fourfold: (1) solving a simple one-period model that describes the optimal bank policy under credit risk; (2) estimating the long-term stochastic processes underlying the risk factors in the balance sheet, taking into account the credit and interest rate cycles; (3) simulating several scenarios for interest rates and charge-offs; and (4) describing the equations that govern the evolution of the balance sheet in the long run. The models that we use address momentum and the interaction between different rates. Our results enable simulation of bank balance sheets over time given a bank’s lending strategy and provides a basis for an optimization model to determine bank asset–liability management strategy endogenously.     

Differences in the Cost of Mortgage Credit Implications for Discrimination

This paper estimates the mortgage interest rate differences paid by Asian, Hispanic, and African–American borrowers to a national home mortgage lender in the years 1988–1989. Controlling for differences in market rates, rate lock protection, and borrower risk factors, conventional loan interest rates are almost perfectly race-neutral. The single deviation from race-neutrality is that when interest rates fall during the borrower's rate-lock period, only African–American borrowers are unable to capture a share of this decline. Government (FHA and VA) credit models show small premia paid by African–American borrowers of about $1.80 per month on average. In government lending, Hispanic borrowers alone are unable to capture rate declines occurring during the borrower's rate-lock period.     

What Determined the Great Cap Rate Compression of 2000–2007, and the Dramatic Reversal During the 2008–2009 Financial Crisis?

In this paper we revisit the many studies that have attempted to explain the determinants of commercial real estate capitalization rates. We introduce two new innovations. First we are able to incorporate two macroeconomic factors that greatly impact cap rates besides treasury rates and local market fundamentals – the variables most commonly used in such research. These are the general corporate risk premium operating in the economy, and the growth rate of debt relative to GDP in the general economy (liquidity). The addition of these factors greatly adds to the ability of previous models to explain the secular fall of cap rates in the last decade and their recent rise – in terms of traditional measures of within-sample fit. Our second innovation is methodological; our analysis uses a large and robust quarterly panel data set of over 30 US metropolitan areas from 1980q1 through 2009q3. With this data we compare 3 models: a “base model” and then one that selectively adds each of our macro-economic variables. We test the ability of each of these models to fit the 2002–2009 period using “back test” dynamic forecasts. Our conclusion is that much of the secular decline in cap rates from 2000 through 2007 and their subsequent rise seem attributable to the macro-economic factors and less to movements in market fundamentals.     

On the consequences of demographic change for rates of returns to capital, and the distribution of wealth and welfare

This paper employs a multi-country large-scale Overlapping Generations model with uninsurable labor productivity and mortality risk to quantify the impact of the demographic transition towards an older population in industrialized countries on world-wide rates of return, international capital flows and the distribution of wealth and welfare in the OECD. We find that for the U.S. as an open economy, rates of return are predicted to decline by 86 basis points between 2005 and 2080 and wages increase by about 4.1%. If the U.S. were a closed economy, rates of return would decline and wages increase by less. This is due to the fact that other regions in the OECD will age even more rapidly; therefore the U.S. is “importing” the more severe demographic transition from the rest of the OECD in the form of larger factor price changes. In terms of welfare, our model suggests that young agents with little assets and currently low labor productivity gain, up to 1% in consumption, from higher wages associated with population aging. Older, asset-rich households tend to lose, because of the predicted decline in real returns to capital.

Government Debt, Reputation and Creditors' Protections: The Tale of San Giorgio

San Giorgio (1407–1805) was a formal association aimed at protecting creditors’ rights and reducing the risk of debt repudiation by the Republic of Genoa. The behavior of this institution is broadly consistent with debt models that predict lending if lenders can impose big penalties on debtors, and models in which lenders can differentiate between excusable and inexcusable defaults. San Giorgio shareholders enjoyed low credit risk but also lower returns on capital than those prevailing on comparable foreign assets for which creditors’ protection mechanisms were lacking. The Republic’s quid pro quo was a low cost of financing. Differences in credit risk were an important explanation of differences in long-term interest rates across countries in 16th and 17th century Europe, a point not sufficiently emphasized by the literature.     

Forecasting the Term Structure of South African Government Bond Yields

This article uses the parsimonious dynamic Nelson–Siegel model to fit the yields of South African government bonds. We find that the dynamic Nelson–Siegel model has good fitting abilities for all maturities. We further forecast the term structure by seven different dynamic Nelson–Siegel models with time series models. We find that the DNS–VAR–GARCH model is useful for forecasting the short-term rates, the DNS–VAR best predicts the medium-term rates, and the DNS–RW best predicts the long-term rates. In addition, the dynamic Nelson–Siegel models provide better forecasts of yield data than a random walk model, especially for the 12-month forecasting horizons.

Medium-Term Money Neutrality and the Effective Lower Bound

Conventional wisdom suggests that medium-term money neutrality imposes strong limitations on the effects of monetary policy. The point of this paper is that models with medium- and long-term money neutrality are prone to generate nonexistence of equilibria at the effective lower bound (ELB) on interest rates. Nonexistence is suggestive of sharp output contractions—so-called contractionary black holes—at the ELB. Paradoxically, the case for expansionary monetary policy at the ELB is even stronger in models that feature near money neutrality. The results highlight the benefits of a monetary policy regime in which the central bank temporarily overshoots its inflation target once confronted by the ELB.
