We examine the cyclicality of budget items among provincial governments in eight federations, showing that own-source taxes are highly pro-cyclical and contra...

Cycling ewes with lesions placed in the anterior region of medial basal hypothalamus (MBH) showed no estrous behavior, but they all had ovulations and cyclical corpora lutea at physiological terms. Participation of the anterior region of MBH in control of sexual behavior was also supported by the experiments on castrated sheep implanted with 17-beta-estradiol into the area determined previously...

This paper studies the role of labor market institutions on unemployment and on the cyclical properties of job flows.

The model is able to reproduce the main cyclical propert...

We find that variations in this present value series are, surprisingly, due more to variation...
