Background: Reduction of under-five year mortality rate by two-thirds by 2015 compared to 1990 level has been adopted as Target 4A in the Millennium Development Goals. Since infant deaths account for over seventy percents of under-five year mortality, the same two-thirds reduction Target of...

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

This paper develops new test methods for m-dependent data. Our approach is based on sample splitting by regular sampling of the original data at lower frequencies, so that standard techniques for testing independence can be used for each individual subsample. We then propose several alternative...
