Consider a non-spanned security CT in an incomplete market. We study the risk/return tradeoffs generated if this security is sold for an arbitrage-free price bC0 and then hedged. We consider recursive “one-period optimal” self-financing hedging strategies, a simple but tractable criterion....

Accepted for publication in the <I>Journal of Business & Economic Statistics</I>.<P> We consider cointegration rank estimation for a p-dimensional Fractional Vector Error Correction Model. We propose a new two-step procedure which allows testing for further long-run equilibrium relations with possibly...</p></i>

type="main" xml:id="jtsa12091-abs-0001"In this article, we propose a new joint portmanteau test for checking the specification of parametric conditional mean and variance functions of linear and nonlinear time-series models. The use of a joint test is motivated for complete control of the...

This article proposes omnibus specification tests of parametric dynamic quantile models. In contrast to the existing procedures, we allow for a flexible specification, where a possible continuum of quantiles is simultaneously specified under fairly weak conditions on the serial dependence in the...

This paper shows that the estimates in the spot return regression in the foreign exchange markets may not convey valid information if exchange rates are generated from the present value model with the near unit discount factor and unit root fundamentals. The main reason is that the present value...

This paper develops new inference methods for m-dependent data. Our approach is based on sample splitting by regular sampling of original data at lower frequencies, so that standard techniques can be used for independent data in individual subsamples. We then explore several alternatives of...

The forward discount puzzle refers to the robust empirical finding that foreign excess returns are predictable. We investigate if expectations errors are the main cause of this predictability using the serial dependence pattern of excess returns implied by economic models as identification...

This paper investigates, both in finite samples and asymptotically, statistical inference on predictive regressions where time series are generated by present value models of asset prices. We show that regression-based tests, including robust tests such as robust conditional test and Q-test, are...

This paper proposes bootstrap assisted specification tests for the autoregressive fractionally integrated moving average model based on the Bartlett <italic>T</italic>-process with estimated parameters whose limiting distribution under the null depends on the estimated model and the estimation method employed....
