Short Horizons (short + horizon)
Selected AbstractsBacktesting Derivative Portfolios with Filtered Historical Simulation (FHS)EUROPEAN FINANCIAL MANAGEMENT, Issue 1 2002Giovanni Barone-Adesi Filtered historical simulation provides the general framework to our backtests of portfolios of derivative securities held by a large sample of financial institutions. We allow for stochastic volatility and exchange rates. Correlations are preserved implicitly by our simulation procedure. Options are repriced at each node. Overall results support the adequacy of our framework, but our VaR numbers are too high for swap portfolios at long horizons and too low for options and futures portfolios at short horizons. [source] The role of permanent and transitory shocks in explaining international health expendituresHEALTH ECONOMICS, Issue 10 2008Paresh Kumar Narayan Abstract While there is a growing literature that examines the issue of cointegration (co-movement over the long run) among health expenditures, there are no studies that examine the issue of common cycles (co-movement over the short run) among health expenditures. We undertake a multivariate variance decomposition analysis of per capita health expenditures of the USA, the UK, Japan, Canada, and Switzerland based on a common-trend,common-cycle restriction framework, to examine the relative importance of permanent and transitory innovations in explaining variations in per capita health expenditures in each of the five countries. Our main finding is that transitory shocks are more important in explaining per capita health expenditures in the UK, Japan, and Switzerland, while permanent shocks dominate variations in per capita health expenditures in the USA and Canada over short horizons.

[source] Conventional and unconventional approaches to exchange rate modelling and assessmentINTERNATIONAL JOURNAL OF FINANCE & ECONOMICS, Issue 1 2008Ron Alquist Abstract We examine the relative predictive power of the sticky price monetary model, uncovered interest parity, and a transformation of net exports and net foreign assets. In addition to bringing Gourinchas and Rey's new approach and more recent data to bear, we implement the Clark,West procedure for testing the significance of out-of-sample forecasts. The interest rate parity relation holds better at long horizons and the net exports variable does well in predicting exchange rates at short horizons in sample. In out-of-sample forecasts, we find evidence that our proxy for Gourinchas and Rey's measure of external imbalances outperforms a random walk at short horizons as do some of the other models, although no single model uniformly beats the random walk forecast.

[source] Estimation Uncertainty and the Equity Premium,INTERNATIONAL REVIEW OF FINANCE, Issue 3 2009HONG YANArticle first published online: 25 AUG 200 ABSTRACT This paper studies a dynamic equilibrium model of asset prices in a partially observable exchange economy. It shows that the precautionary savings motive in response to estimation uncertainty can dominate the risk aversion effect, resulting in the reduction of the equity premium over short horizons. This exacerbates the equity premium puzzle. Over longer holding horizons, however, estimation uncertainty does induce higher risk premiums on equity over risk-free coupon bonds of matching maturities, as long-term bond yields are lowered due to the precautionary savings effect. [source] Forecasting interest rate swap spreads using domestic and international risk factors: evidence from linear and non-linear modelsJOURNAL OF FORECASTING, Issue 8 2007Ilias Lekkos Abstract This paper explores the ability of factor models to predict the dynamics of US and UK interest rate swap spreads within a linear and a non-linear framework. We reject linearity for the US and UK swap spreads in favour of a regime-switching smooth transition vector autoregressive (STVAR) model, where the switching between regimes is controlled by the slope of the US term structure of interest rates. We compare the ability of the STVAR model to predict swap spreads with that of a non-linear nearest-neighbours model as well as that of linear AR and VAR models. We find some evidence that the non-linear models predict better than the linear ones. At short horizons, the nearest-neighbours (NN) model predicts better than the STVAR model US swap spreads in periods of increasing risk conditions and UK swap spreads in periods of decreasing risk conditions. At long horizons, the STVAR model increases its forecasting ability over the linear models, whereas the NN model does not outperform the rest of the models.,,Copyright © 2007 John Wiley & Sons, Ltd. [source] Can cointegration-based forecasting outperform univariate models?JOURNAL OF FORECASTING, Issue 5 2002An application to Asian exchange rates Abstract Conventional wisdom holds that restrictions on low-frequency dynamics among cointegrated variables should provide more accurate short- to medium-term forecasts than univariate techniques that contain no such information; even though, on standard accuracy measures, the information may not improve long-term forecasting. But inconclusive empirical evidence is complicated by confusion about an appropriate accuracy criterion and the role of integration and cointegration in forecasting accuracy. We evaluate the short- and medium-term forecasting accuracy of univariate Box,Jenkins type ARIMA techniques that imply only integration against multivariate cointegration models that contain both integration and cointegration for a system of five cointegrated Asian exchange rate time series. We use a rolling-window technique to make multiple out of sample forecasts from one to forty steps ahead. Relative forecasting accuracy for individual exchange rates appears to be sensitive to the behaviour of the exchange rate series and the forecast horizon length. Over short horizons, ARIMA model forecasts are more accurate for series with moving-average terms of order >1. ECMs perform better over medium-term time horizons for series with no moving average terms. The results suggest a need to distinguish between ,sequential' and ,synchronous' forecasting ability in such comparisons. Copyright © 2002 John Wiley & Sons, Ltd. [source] Extracting the Expected Path of Monetary Policy From Futures RatesTHE JOURNAL OF FUTURES MARKETS, Issue 8 2004Brian SackArticle first published online: 8 JUN 200 Federal funds and eurodollar futures contracts are among the most useful instruments for deriving expectations of the future path of monetary policy. However, reading policy expectations from those instruments is complicated by the presence of risk premia. This paper demonstrates how to extract the expected policy path under the assumption that risk premia are constant over time, and under a simple model that allows risk premia to vary. In the latter case, the risk premia are identified under the assumption that policy expectations level out after a long enough horizon. The results provide evidence that the risk premia on these futures contracts vary over time. The impact of this variation is fairly limited for futures contracts with short horizons, but it increases as the horizon of the contracts lengthens. © 2004 Wiley Periodicals, Inc.

We computed returns, risks and end-of-period wealth distributions of various Canadian asset classes at increasing horizons between 1957 and 2003, based on the bootstrapping technique. Results show that investment outcomes at short horizons can be quite different from outcomes at longer horizons. Evidence is provided in favour of time diversification, while the current market practice of life cycle investing is not fully supported as stocks continue to exhibit more favourable risk-return payoffs than other asset classes, even at shorter time intervals. Résumé Cet article se propose d'étudier le bien-fondé de la pratique actuelle qui consiste à recommander des actions aux investisseurs dans leur jeunesse et l'argent liquide ou les obligations lorsqu'ils approchent l'âge de la retraite. Grâce à la technique de bootstrapping, nous calculons les retours sur investissement, les risques et la distribution de richesse en fin de période pour plusieurs types d'actifs canadiens à horizons divers entre 1957 et 2003. Les résultats présentent des différences importantes entre les investissements à court terme et les investissements à long terme. Les données disponibles soutiennent l'idée de la diversification temporelle et réfutent partiellement la pratique actuelle du cycle de vie d'investissement. De fait, les actions comportent toujours un profil risques-bénéfices plus favorable que les autres types d'actifs, même pour des intervalles de temps réduits. [source] | ||||||||||
