We report here two cases of vitiligo vulgaris successfully treated with the combination therapy of topical steroid and vitamin D3 compound and currently maintained by vitamin D3 analog without any adverse effects: skin atrophy, striae or telangiectasia on the exposed areas. The best-known mechanism of topical vitamin D3 analog is the enhancement of(More)
We present an alternative explanation of the positive relationship between total fertility rate (TFR) and female labor participation rate (FLPR) observed in recent cross section of OECD countries. We first use a general equilibrium model with vertical quality differentiation and heterogeneous labor and show how low fertility is associated with consumption(More)
We present an alternative explanation of the positive relationship between total fertility rate (TFR) and female labor participation rate (FLPR) observed in recent cross section of OECD countries. We first use a simple model of consumer behavior where consumption good is indexed by quality, both consumption and child rearing require time and a physical good(More)
