Long-term interest rates,risk premia and unconventional monetary policy

We study two kinds of unconventional monetary policies: announcements about the future path of the short-term rate and long-term nominal interest rates as operating instruments of monetary policy. We do so in a model where the risk premium on long-term debt is, in part, endogenously determined. We find that both policies are consistent with unique equilibria, that, at the zero lower bound, announcements about the future path of the short-term rate can lower long-term interest rates through their impact both on expectations and on the risk premium and that long-term interest rate rules perform as well as, and at times better than, conventional Taylor rules. With simulations, we show that long-term interest rate rules generate sensible dynamics both when in operation and when expected to be applied.     

Financial Pressure and Balance Sheet Adjustment by Firms*

This paper examines the financial policies and balance sheet adjustment of companies. Using a large panel of UK‐listed firms we consider how companies resolve pressures on their balance sheet, estimating models for dividends, new equity issuance and investment. The results indicate that companies resolve balance sheet pressures by each of these means. Financial policies, through dividends and new equity issuance, and real investment decisions, respond to the underlying level of debt and the borrowing cost of servicing that debt. Dividends are estimated to be slow to adjust in the short run.     

A SECURITISED MARKET FOR HUMAN CAPITAL

This paper proposes a simple finance innovation with an income‐contingent repayment system to supplement our current fixed‐interest rate student loan system. Income‐contingent repayments could be pooled and securitised while lenders could sell these lifetime equity‐like human capital securities to investors who seek to diversify their existing portfolios. Without increasing the government's fiscal burden, this innovation would significantly reduce entry barriers facing finance‐constrained college students in a continually rising cost environment.     

Reducing estimation risk in optimal portfolio selection when short sales are allowed

The issue of estimation risk is of particular interest to the decision‐making processes of portfolio managers who use long–short investment strategies. Accordingly, our paper explores the question of whether a VaR constraint reduces estimation risk when short sales are allowed. We find that such a constraint notably decreases errors in estimates of the expected return, standard deviation, and VaR of optimal portfolios. Furthermore, optimal portfolios in the presence of the constraint are substantially closer to the ‘true’ efficient frontier than those in its absence. Finally, we provide VaR bounds and confidence levels for the constraint that lead to the best out‐of‐sample performance. Copyright © 2008 John Wiley & Sons, Ltd.     

Robust bubbles with mild penalties for default

Limited enforcement of debt contracts and mild penalties for default can lead to low equilibrium interest rates, to ensure debt repayment. Low interest rates, in turn, create conditions for bubbles. I show that bubbles in unsecured private debt exist when the punishment for default is a permanent or a temporary interdiction to trade. Bubbles are an inefficient source of liquidity, as they lower interest rates and reduce welfare by discouraging saving.     

Fixed versus floating: vulnerability to rising interest rates

• ? Looking at different economies' exposure to fixed‐ and floating‐rate private‐sector debt reveals how vulnerable they could be to rising interest rates. Our analysis finds that Hong Kong, Sweden, China and Australia are potentially most exposed via floating rates to rising debt service costs. A 150bp rise in rates would also push several other countries' debt service ratios above the peaks of 2008. Less vulnerable economies include the US and Germany.
• ? High levels of floating‐rate debt imply a large and rapid pass‐through of rising interest rates to firms and households, with negative consequences. Exposure to floating‐rate debt as a share of GDP varies greatly: the highest levels are in Hong Kong, China, Sweden, Australia and Spain, with the lowest levels in the US, France and Germany.
• ? Growing shares of fixed‐rate housing debt in the US, Eurozone and UK mean the impact of higher interest rates may be less severe than a decade ago. Private deleveraging in countries such as the US, UK and Spain could also soften the impact.
• ? A rise of 100bp in short‐term interest rates would raise the debt service ratio after one year by around 2.5% of GDP in Hong Kong, with increases of 1.5–1.7% of GDP in Sweden, China and Australia. The smallest effects would be in the US and Germany.
• ? A 100–150bp rate rise would push debt service ratios in China, Hong Kong, Canada, France and the Netherlands well above their peaks of a decade ago. A similar rate rise would take debt service ratios in Sweden, South Korea and Australia close to, or above, previous peaks.
• ? The distribution of debt within economies, which our analysis does not cover, is also important. For example, there is some evidence that the US corporate sector has a high concentration of debt among borrowers with weak finances. Countries that are highly vulnerable to interest rate rises may see their central banks normalise policy rates more slowly than they otherwise would.

     

How Do Alphas and Betas Move? Uncertainty,Learning and Time Variation in Risk Loadings*

I employ a parsimonious model with learning, but without conditioning information, to extract time‐varying measures of market‐risk sensitivities, pricing errors and pricing uncertainty. The evolution of these quantities has interesting implications for macroeconomic dynamics. Parameters estimated for US equity portfolios display significant low‐frequency fluctuations, along patterns that change across size and book‐to‐market stocks. Time‐varying betas display superior predictive accuracy for returns against constant and rolling‐window OLS estimates. As to the relationship of betas with business‐cycle variables, value stocks’ betas move pro‐cyclically, unlike those of growth stocks. Investment growth, rather than consumption, predicts the betas of value and small‐firm portfolios.     

The economic principles of pension provision

To examine pensions Samuelson's overlapping-generations model is generally used: its basic workings are set out here for an open economy. Pay-as-you-go (PAYGO) pensions are attractive when the rate of population growth exceeds the real rate of interest; then all generations are better off for the existence of the pension. The only cost is the income tax distortion. Once the rate of growth falls below the real interest rate, only the cost is left and it is better for the state to'fund'its pensions. If the state borrows to finance the transition to a funded system, it substitutes explicit debt for unfunded liabilities, which leaves its balance sheet unchanged; this avoids the problem of the existing young generation'paying twice'for its pensions.     

The great rotation in global credit risks

• ? The pattern of global credit risks looks very different today than in 2007. Risks are now mostly centred in China and emerging markets. “Excess” private debt in China is as high as $3 trillion compared with $1.7 trillion in the US a decade ago. Yet some pockets of significant risk still exist in advanced economies, which not only implies vulnerability to rising interest rates, but also that the scope for rate rises may be limited.
• ? With policy normalisation underway in the US and the scaling back of asset purchases expected to start soon in the Eurozone, we focus on assessing vulnerabilities across global credit markets. This article explores the topic using a top‐down, cross‐country approach. We find that although private debt and debt service ratios look more benign in advanced economies than a decade ago, they have deteriorated markedly in many emerging markets in recent years.
• ? Based on a measure of excess private debt – comparing private credit‐to‐GDP ratios with their trend – China, Hong Kong and Canada are the riskiest. When comparing debt service ratios relative to their long‐term averages, risks are also mainly concentrated in emerging countries. But Canada, Australia and some smaller European countries also have high debt service ratios that have failed to drop since 2007, despite the slump in global interest rates.
• ? Overall, aggregate private debt indicators look less worrying than in 2007. We would also argue that the concentration of excess private debt levels in China reduces the risk of a sudden financial crisis based on massive credit losses, such as the one in 2007–2010. But with corporate debt levels in the US, Canada and some other G7 countries above their long‐term trend, investors need to be attentive to these considerable pockets of risk.

     

When Does Government Debt Crowd Out Investment?

We examine when government debt crowds out investment for the US economy using an estimated New Keynesian model with detailed fiscal specifications and accounting for monetary and fiscal policy interactions. Whether investment is crowded in or out in the short term depends on policy shocks triggering debt expansions: higher debt can crowd in investment for cutting capital tax rates or increasing government investment. Contrary to the conventional view, no systematic relationships between real interest rates and investment exist, explaining why reduced‐form regressions are inconclusive about crowding out. At longer horizons, distortionary financing is important for the negative investment response to debt. Copyright © 2013 John Wiley & Sons, Ltd.     

Sovereignty, Separation and Risk Premiums

This study investigates the risk premia of Canadian debt issuers in the U.S. capital markets under conditions of sovereignty stress. In particular, the impact of separatist activity is considered. The incidence of separation news around the sale of debt issues is associated with a specific increase in the proceeds yield or cost to the issuer, but not the market yield. Debt issues by Quebec parties within the separation news event window had an added cost. The added cost is estimated at more than 0.56% to the issuer or about $1.30 million per average $230.77 million issue. These costs are additional fees that are paid to the investment banking syndicate, but these do not increase the yield to the investors. Brown, Durbin and Evans (BDE) recursive residuals tests support the hypothesis of structural changes over time in the pricing process. Debt issues from other countries facing political risk may be priced in a similar manner.     

The Fama-French model for estimating the cost of equity capital: The impact of real options of investment projects

We use the classic and modified Fama-French models to estimate the cost of capital of stock portfolios listed on selected markets. We compare four highly developed markets (US, EU, Japanese and global) and the Polish market as an alternative investment opportunity and a CEE emerging market. The performance of the applied procedures for estimating the cost of capital for company projects is examined and cost of capital is assessed with and without real option adjustment. We adjust the portfolios’ returns using the firms’ book-to-market ratios and idiosyncratic volatility as option proxies. The variability of cost of capital is evaluated using bootstrap methods. Our study shows a clear difference between bootstrapped distributions of cost of capital for the tested developed market and the Polish market portfolios. Wider confidence intervals of the estimated cost of capital of the studied Polish portfolios may result from political motivations in managing state-controlled companies. Our findings also indicate a clear difference between the cost of capital for tested portfolios with and without option adjustment. The widths of the estimated confidence intervals increase after option adjustment. The highest/lowest values of the cost of capital both with and without option adjustment are found for the US/Japanese market portfolios.     

The Impact of Thin‐Capitalization Rules on External Debt Usage – A Propensity Score Matching Approach

Thin‐capitalization rules (TCRs) aim at limiting the tax advantage of internal debt financing by restricting the tax deductibility of the corresponding interest expenses. This article examines how subsidiaries of multinational firms respond to a change in the German thin‐capitalization legislation. The empirical analysis not only demonstrates that the TCR effectively restricts internal debt financing, it also suggests that firms are able to avoid taxation of interest by substituting external for internal debt. The empirical approach applies propensity score matching techniques and exploits the German tax reform 2001 to solve endogeneity problems.     

An assessment of Portuguese banks’ efficiency and productivity towards euro area participation

This paper analyses the production technology of Portuguese banks during the 1992–2006 period through the estimation of a translog cost frontier. This period is of major interest because it covers Portugal’s euro area accession and its impact on the banking system. Hence, critical factors impacting the banking system are identified against the background of increasing financial integration prior to the financial crisis that started in 2007 and later translated into strains in some European sovereign debt markets. Banks are modelled as firms which produce loans and other earning assets, choosing the cost minimizing combination of labour, capital and interest bearing debt, subject to holding a predetermined level of equity. According to the results of this study, technological progress has shifted the cost frontier downwards throughout the period under consideration, whereas the distance at which banks have operated from the frontier seems to have remained constant. Further, increases in production under scale economies have also contributed to the recorded increase in productivity.     

Higher interest rates should not unduly faze consumers

• ? Though the MPC has signalled a more aggressive pace of interest hikes than previously anticipated, we still expect the impact on the consumer sector in aggregate to be modest. We estimate that household debt servicing costs will rise from the current level of 4.1% of household income to 5.0% by the end of 2019. This would still be only a little over half the pre‐crisis peak.
• ? We expect the MPC to hike interest rates twice in both 2018 and 2019, taking Bank Rate to 1.5% by the end of next year. Higher interest rates will impact on consumer spending by increasing debt servicing costs and reducing the attractiveness of credit (including mortgages), but savers will benefit from higher returns on their deposits.
• ? Mortgages account for 77% of loans to UK households and full pass through of a 100bp rise in Bank Rate to variable rate loans, implying an increase from 2.78% to 3.78%, would add £100 a month to the cost of servicing an average mortgage. But only two‐fifths of borrowers have a variable rate deal, so for many homeowners the adjustment to higher interest rates will not be immediate. And the proportion of houses which are owned via a mortgage has fallen over the past decade, suggesting that the household sector as a whole will be less sensitive to higher mortgage interest rates.
• ? Historically the relationship between Bank Rate and interest rates on unsecured lending has been weak and rates on credit cards and personal loans have not yet risen following November's rate hike. The link to deposit rates has been stronger and higher returns on savings will mitigate some of the damage to household income from higher debt servicing costs, although uneven distribution of debt and savings means that there will be winners and losers at a more disaggregated level.
• ? We have used the Oxford Economics Global Economic Model to run a counterfactual scenario where Bank Rate is kept at 0.5% throughout 2018 and 2019. The results suggest that the pace of rate hikes assumed in our baseline forecast would reduce the level of consumer spending by 0.2 percentage points by the end of 2019.

     

Intertemporal consumption choices,transaction costs and limited participation in financial markets: reconciling data and theory

This paper builds a unifying framework based on the theory of intertemporal consumption choices that brings together the limited participation‐based explanation of the Consumption Capital Asset Pricing Model's poor empirical performance and the transaction costs‐based explanation of incomplete portfolios. Using the implications of the consumption model and observed household consumption and portfolio choices, we identify the preference parameters of interest and a lower bound for the costs rationalizing non‐participation in financial markets. Using the US Consumer Expenditure Survey and assuming isoelastic preferences, we estimate the coefficient of relative risk aversion at 1.7 and a cost bound of 0.4% of non‐durable consumption. Our estimate of the preference parameter is theoretically plausible and the bound sufficiently small to be likely to be exceeded by the actual total (observable and unobservable) costs of participating in financial markets.

Private debt overhang and the government spending multiplier: Evidence for the United States

Using state‐dependent local projections and historical US data, we find that government spending multipliers are considerably larger in periods of private debt overhang. In particular, while multipliers are below or close to one in low private debt states, we find significant crowding‐in of private spending in periods of debt overhang, resulting in multipliers that are much larger than one. In high private debt episodes, more government purchases even reduce the ratio of government debt to gross domestic product. These results are robust for the type of shocks, and when we control for the business cycle, financial crises, deleveraging episodes, government debt overhang, and the zero‐lower‐bound.     

Fitting and Forecasting Sovereign Defaults using Multiple Risk Signals

In this article, we try to realize the best compromise between in‐sample goodness of fit and out‐of‐sample predictability of sovereign defaults. To do this, we use a new regression‐tree based approach that signals impending sovereign debt crises whenever pre‐selected indicators exceed specific thresholds. Using data from emerging markets and Greece, Ireland, Portugal and Spain (GIPS) over the period 1975–2010, we show that our model significantly outperforms existing competing approaches (logit, stepwise logit, noise‐to‐signal ratio and regression trees), while balancing in‐ and out‐of‐sample performance. Our results indicate that illiquidity (high short‐term debt to reserves) and default history, together with real GDP growth and US interest rates, are the main determinants of both emerging market country defaults and the recent European sovereign debt crisis.     

How Controlling Shareholders Impact Debt Maturity Structure in Taiwan

Using data on listed companies in Taiwan from 1998 to 2009, our study investigates how controlling shareholder structure can affect debt maturity structure. The results indicate a significant negative relationship between ownership and debt maturity in the sample companies when control rights are lower than required control shareholdings. Conversely, the results also demonstrate that the separation of control from ownership displays a significant positive impact on debt maturity for controlling shareholder structure when control rights exceed cash‐flow rights. Overall, our results show that there is an inverted U‐shaped non‐linear relationship between control rights and the duration of liabilities in the control structure of ultimate controlling shareholders. Further, the consequence is that we find the required control shareholdings ratio serves as an important criterion in analyzing it, when dividing the control rights structure based on controlling shareholders into different combinations.     

After Modigliani,Miller, and Hamada: A new way to estimate cost of capital

In this article, we discuss the impact of financial debt on shareholder value using a new approach that aims: (a) to explain the effect that leverage from debt has on a stock’s systematic risk, or what we shall call here “the systematic cost of leverage,” and (b) to account for default risk in the cost of equity, or what we shall call here “the cost of default.” Our assessment of systematic risk is based on a stochastic approach that is materially different from the one proposed by Hamada: the risk premium remunerates the investor for the probability of equity (expressed as market value) generating a return below that of the risk‐free rate. Furthermore, the approach we use to account for default risk is derived from reduced‐form models, but in this case, (a) we use real probabilities of default and not risk‐neutral probabilities, and (b) we extend the approach to stocks.
