So, it should be better to use "bicubic" to enlarge an image and "nearest neighbor" to reduce it. This is not so simple unfortunately, as the "nearest neighbor" reduction gives unpleasant images with too much pixel to pixel modulation. The intermediate "bilinear" gives more natural looking pictures, but "bicubic" should definetely be avoided, as it blurs the image. A little unsharp masking (with radius <1) helps also in this case.
As a conclusion, always use "bicubic" interpolation to enlarge an image, and "bilinear" (+slight unsharp masking) to reduce its size.
