Non-Parametric Regression Models of Deviations from Othogonality in the Expectations Theory of the Term Structure

Regression tests of the expectations theory of the term structure typically reject the null hypothesis of orthogonality between implied forecast errors and the yield spreads. In the statistical literature on the term structure, these rejections are sometimes attributed to time-varying liquidity premia, and Engle et al . (1987) suggest that the ARCH-M model of time-variation in the liquidity premium may be sufficient to account for rejections of the expectations theory. We use non-parametric (kernel) regression to explore the regression test results on a number of data sets, and find some evidence of a persistent deviation from orthogonality for large absolute values of the spread. Incorporating ARCH-in-mean into models of the term premium indicates that this specification does explain significant time variation in liquidity premia, but the effect does not apepar to be sufficient to account for all of the deviations from orthogonality of forecast errors and spreads.     

A multivariate GARCH in mean approach to testing uncovered interest parity: evidence from Asia-Pacific foreign exchange markets

The existence of time-varying risk premia in deviations from uncovered interest parity (UIP) is investigated based on a conditional capital asset pricing model (CAPM) using data from four Asia-Pacific foreign exchange markets. A parsimonious multivariate generalized autoregressive conditional heteroskedasticity in mean (GARCH-M) parameterization is employed to model the conditional covariance matrix of excess returns. The empirical results indicate that when each currency is estimated separately with an univariate GARCH-M parameterization, no evidence of time-varying risk premia is found except Malaysian ringgit. However, when all currencies are estimated simultaneously with the multivariate GARCH-M parameterization, strong evidence of time-varying risk premia is detected. As a result, the evidence supports the idea that deviations from UIP are due to a risk premium and not to irrationality among market participants. In addition, the empirical evidence found in this study points out that simply modeling the conditional second moments is not sufficient enough to explain the dynamics of the risk premia. A time-varying price of risk is still needed in addition to the conditional volatility. Finally, significant asymmetric world market volatility shocks are found in Asia-Pacific foreign exchange markets.     

Expectations Formation and Risk in Three Financial Markets: Surveying What the Surveys Say

This paper attempts to provide a logical overview of the literature which exploits survey data to examine issues of expectations formation and risk aversion in financial markets. Our survey suggests that: short term expectations are excessively volatile and exhibit bandwagon effects, while longer term expectations appear to be regressive and therefore stabilising; in bond and foreign exchange markets the standard result of forward rate biasedness is due in part to time-varying premia; recent research using disaggregate foreign exchange survey data demonstrates the importance of heterogeneous expectations.     

The maturity structure of term premia with time-varying expected returns

This paper analyzes the maturity structure of term premia using McCulloch’s US Treasury yield curve data from 1953–91, allowing expected returns to vary across time. One, 3, 6, and 12 month holding period returns on maturities up to 5 years are projected on 3 ex ante variables to compute time-varying expected returns, and simulations are employed to generate distributions of conditionally expected return premia. The likelihood of expected returns monotonically increasing in maturity (as implied by the liquidity preference hypothesis) is relatively high when the yield curve is steep and interest rates are high, and with longer holding periods, but low in other cases. The hypothesis that intermediate maturity bonds have the highest expected returns (a “hump-shaped” maturity-return pattern) around the onset of recessions does not receive much support.     

Japan’s impactful augmentation of quantitative easing sovereign-bond purchases

This article examines how and to what extent large-scale government bond purchases in the Bank of Japan’s monetary policy affected two components of long-term interest rates over the period 2009–2015. The article divides market yields on popular 5 and 10-year government bonds into future policy-rate expectations with uncertainty and a specific type of term premia required by investors for the bonds’ demand/supply imbalances, by using overnight index swap rates as a proxy for the former. The Bank of Japan augmented the purchases substantially by starting Quantitative and Qualitative Monetary Easing (QQME) in 2013. The QQME became impactful in the sense that it encouraged investors to improve the first component whilst reducing the second component. These appeared mainly as persisting announcement-effects – upward level shifts of the expectations and downward ones of the term premia. The reduction of term premia was much greater for the 10-year maturity than for 5-year one and strengthened after an additional expansion of the QQME in 2014. The QQME is estimated to have enhanced 5-year sovereign bond yields by 11.9 basis points (bps) a month on average whilst reducing 10-year ones by 8.3 bps. The impact on the 5-year yields turned to be negative after the QQME expansion.     

The informational content of credit rating announcements for share prices in a small market

The informational value of credit ratings is a subject of continuing debate. This research examines whether reaction to small market credit rating announcements is different from large markets, due to limited information, liquidity premia, and analyst neglect factors. Unlike U.S. and Australian studies that find a significant reaction to only bad news, a significant positive reaction to both positive placements and upgrades is found in the New Zealand market. Further, significant market reaction largely accrues to firms not cross-listed in U.S. markets. This evidence suggests credit rating agencies act as substitute information providers for firms followed by relatively few analysts. A substantial portion of this research was completed while author Meyer was affiliated with Massey University, Albany Campus, Auckland, New Zealand.     

Asset Pricing with Observable Stochastic Discount Factors

The stochastic discount factor model provides a general framework for pricing assets. By specifying the discount factor suitably it encompasses most of the theories currently in use, including CAPM and consumption CAPM. The SDF model has been based on the use of single and multiple factors, and on latent and observed factors. In most situations, and especially for the term structure, single factor models are inappropriate, whilst latent variables require the somewhat arbitrary specification of generating processes and are difficult to interpret. In this paper we survey the principal different implementations of the SDF model for bonds, equity and FOREX and propose a new approach. This is based on the use of multiple factors that are observable and modelling the joint distribution of excess returns and the factors using a multi–variate GARCH–in–mean process. We argue that in general single equation and VAR models, although widely used in empirical finance, are inappropriate as they do not satisfy the no–arbitrage condition. Since risk premia arise from conditional covariation between the returns and the factors, both a multi–variate context and having conditional covariances in the conditional mean process, is essential. We explain how apparent exceptions, such as the CIR and Vasicek models, in fact meet this requirement — but at a price. We explain our new approach, discuss how it might be implemented and present some empirical evidence, mainly from our own researches. Partly, to enable comparisons to be made, the survey also includes evidence from recent empirical work using more traditional approaches.     

Debt stabilization games in the presence of risk premia

As a result of the recent financial crisis and the ensuing economic recession, fiscal deficits have soared in many OECD countries. As a consequence, government debt has been on the rise again after a period of stable or declining government debt. In this paper we analyze debt stabilization in a country that features endogenous risk premia, imposed by financial markets that evaluate the probability of debt default by governments. Endogenous risk premia arise by assuming, e.g., simple linear relations between risk premia and the level of debt. As a result the real interest rate on government debt can be written as a constant (measuring the risk-free real interest rate corrected for real output growth) plus an endogenous risk premium that depends on the debt level. We bring such an endogenous risk premium into Tabellini (1986) model and analyze the impact of it. This gives rise to a non-linear differential game. We solve this game for both a cooperative setting and a non-cooperative setting. The non-cooperative game is solved under an open-loop information structure. We present a bifurcation analysis w.r.t. the risk premium parameter.     

Business start-ups or disguised unemployment? Evidence on the character of self-employment from transition economies

We study the character of self-employment, drawing upon household survey evidence from six transition economies. Multinomial-logit analysis distinguishing employers from own-account self-employed and comparing both groups to employees and unemployed finds that own-account status is intermediate in most characteristics; tests reject the pooling of any of these categories. Selectivity-bias-corrected earnings premia are large for employers and smaller for own-account. A structural polychotomous model shows that employers respond strongly to predicted earnings premia in all countries, while the own-account response is estimated to be negative, supporting the interpretation that individuals may be pushed into own-account status by lack of work opportunities.     

Tests of asset pricing with time‐varying factor loads

This paper proposes an empirical asset pricing test based on the homogeneity of the factor risk premia across risky assets. Factor loadings are considered to be dynamic and estimated from data at higher frequencies. The factor risk premia are obtained as estimates from time series regressions applied to each risky asset. We propose Swamy‐type tests robust to the presence of generated regressors and dependence between the pricing errors to assess the homogeneity of the factor risk premia and the zero intercept hypothesis. An application to US industry portfolios shows overwhelming evidence rejecting the capital asset pricing model, and the three and five factor models developed by Fama and French (Journal of Financial Economics, 1993, 33, 3–56; Journal of Financial Economics, 2015, 116, 1–22). In particular, we reject the null hypotheses of a zero intercept, homogeneous factor risk premia across risky assets, and the joint test involving both hypotheses.     

Firm-specific Human Capital Accumulation: Evidence from Brazil*

We introduce firm-specific returns to experience and tenure into a standard two-way fixed effects model, show that they are separately identified under the standard exogenous mobility assumption and with sufficient between firm mobility, and provide a new evidence on heterogeneity of returns to experience and tenure across firms using the administrative data from Brazil over the years 1999–2014. We document that (1) returns to tenure are not strongly related to firm wage premia, (2) returns to experience are strongly negatively correlated with firm wage premia, (3) the relationship between firm wage premium and return to experience is stronger for ‘blue collar’ firms.     

Merger Premia and National Differences in Accounting for Goodwill

We examine the effects of international accounting diversity on the market for corporate control with particular reference to whether national differences in the treatment of purchased goodwill are associated with differences in premia offered by U.K. as opposed to U.S. acquirers of U.S. targets. We find merger premia associated with U.K. acquisitions to be consistently higher than those for U.S. acquisitions. Moreover, higher premiums offered by U.K. acquirors appear to be associated with not having to amortize goodwill to earnings. The evidence provided here suggests that national differences in accounting impact differentially on managerial behavior.     

Has the equity premium been low for 40 years?

There is an increasingly prevalent view among financial economists that the ex-ante equity premium has declined over the last 50 years. In this paper, we present new empirical evidence indicating that there was a structural break in the equity premium in both the U.S. and Europe in the immediate post-WWII period driven by a decline in consumption risk. This is confirmed in complete, segmented and incomplete market settings. The results of this paper demonstrate that the discrepancy between the ex-post and ex-ante equity premia is not a recent phenomenon.     

Prevention incentives in long‐term insurance contracts

Long‐term insurance contracts are widespread, particularly in public health and the labor market. Such contracts typically involve monthly or annual premia which are related to the insured's risk profile. A given profile may change, based on observed outcomes which depend on the insured's prevention efforts. The aim of this paper is to analyze the latter relationship. In a two‐period optimal insurance contract in which the insured's risk profile is partly governed by her effort on prevention, we find that both the insured's risk aversion and prudence play a crucial role. If absolute prudence is greater than twice absolute risk aversion, moral hazard justifies setting a higher premium in the first period but also greater premium discrimination in the second period. This result provides insights on the trade‐offs between long‐term insurance and the incentives arising from risk classification, as well as between inter‐ and intragenerational insurance.     

Effects of Alternative Goodwill Treatments on Merger Premia: Further Empirical Evidence

In this study, we extend our analysis of the effects of international accounting diversity on market behavior. Specifically we examine whether national differences in the treatment of purchased goodwill are associated with differences in premia offered by non-U.S. acquirers other than the British when bidding for U.S. target companies. We find merger premia offered by foreign acquirors who enjoy advantageous accounting or tax treatments relative to U.S. acquirors to be higher, on average, than those offered by U.S. acquirors. Regression analyses show that goodwill accounting does explain merger premia. The higher coefficient on goodwill in German acquisitions, relative to Japanese acquisitions, indicates that merger premia are associated with accounting diversity among various countries in the sense that, while tax benefits are available in both Japan and Germany, more favorable accounting treatments are operative in the latter.     

Alternative econometric implementations of multi-factor models of the U.S. financial markets

This paper analyzes the empirical performance of two alternative ways in which multi-factor models with time-varying risk exposures and premia may be estimated. The first method echoes the seminal two-pass approach introduced by Fama and MacBeth (1973). The second approach is based on a Bayesian latent mixture model with breaks in risk exposures and idiosyncratic volatility. Our application to monthly, 1980–2010 U.S. data on stock, bond, and publicly traded real estate returns shows that the classical, two-stage approach that relies on a nonparametric, rolling window estimation of time-varying betas yields results that are unreasonable. There is evidence that most portfolios of stocks, bonds, and REITs have been grossly over-priced. On the contrary, the Bayesian approach yields sensible results and a few factor risk premia are precisely estimated with a plausible sign. Predictive log-likelihood scores indicate that discrete breaks in both risk exposures and variances are required to fit the data.     

Does Austerity Work? Theory and Evidence

• A number of factors underpin the Coalition's fiscal strategy, the most important being the use of rules (for the structural current deficit and net debt) and the creation of a new “institution”, the OBR, to monitor it. According to the Chancellor, this combination would ensure the government's “credibility and avoid elevated sovereign default premia and foster sustainable recovery.” 1
• It is already clear that the limited degree of independence for the OBR is a major shortcoming but there is another, more serious, problem in the Treasury's belief that the deficit ratio can be reduced by making spending cuts as clear failures by the government to achieve its fiscal targets on the deficit have shown. Such a failure is consistent with the results of research over the last decade which gives strong support to the view that fiscal multipliers are much larger than unity.
• The length of the downturn, the repeated large failures to hit deficit reduction targets and now the source and nature of the recovery show that his plan is failing. The former was predictable from the evidence just noted. In turn, the recovery relies on the surge in consumer demand following the easing of credit conditions for house purchase and points to a switch to a “Plan B”. It also demonstrates that the Chancellor could have brought about recovery very much earlier had he stimulated demand on taking office not reducing it with his self‐imposed austerity measures. He could even have stimulated demand to a much more constructive long‐term effect by increasing public investment.

     

Market anticipation of merger activities: An empirical test

This paper empirically examines the possibility that there is leakage of information regarding a merger prior to the announcement of the first bid for the target firm. The tests for the existence of market anticipation are based on the behavior of variances implied in the premia of call options listed on the target firms' stocks. We conclude that the evidence is consistent with the hypothesis that the market anticipates an acquisition prior to the first announcement.
