This study presents evidence for the existence of job polarization in Japan, identifies its effects across four age cohorts, and shows its relationship to Japan's business cycles during 1984-2010. The findings indicate that middle-skilled occupations decreased most sharply among the youngest...

In this paper, we reassess labor-market adjustment using an indicator of occupational income unfairness (OIU) that shows whether workers are paid what is warranted by their effort. Although an empirically derived unfairness indicator does not necessarily reflect workers' perceived unfairness,...

In this paper, we reassessed labor-market adjustment by using an indicator of occupational income unfairness (OIU) which shows whether workers are paid equal to what is warranted by their effort. Although an empirically derived unfairness indicator does not necessarily reflect workers' perceived...

Depletion of water resources requires us to search for non-conventional strategies for water preservation and irrigation. Sustainable management of such water resources along with the development of sustainable irrigation systems will contribute to the stability of agricultural yield that is a...

This paper focuses on the drastic increase observed in the Japanese male suicide rate in the late 1990s and early 2000s and confirms unemployment and personal bankruptcy to be the associated socioeconomic factors behind the male suicide variation. Personal bankruptcy is also confirmed to be...

A univariate real-valued function is said to be completely monotone if it takes positive values and alternate the signs of its higher order derivatives, starting from everywhere negative first derivatives. We prove that the representative consumer's discount factor of a continuous-time economy...

We prove that every continuous-time model in which all consumers have time-homogeneous and time-additive utility functions and share a common probabilistic belief and a common discount rate can be reduced to a static model. This result allows us to extend some of the existing results on the...

This paper describes the results of a field expedition work along the rivers Vakhsh and Pyandzh in Tajikistan and Afghanistan within the framework of a Joint Research Project: Investigation of natural resources of Central Asia and reconstruction of agriculture in Afghanistan, supported by the...

This paper includes the following parts: 1) "Vertical or Triangle? Local, regional and federal government in the Russian Federation after Law 131.", by Adrian Campbell, and 2) comments to the paper "Softness and hardness of the institutions in Russian ocal self-government" by Satoshi Mizobata,...

This paper studies a Monte Carlo algorithm for computing distributions of state variables when the underlying model is a Markov process. It is shown that the L1 error of the estimator always converges to zero with probability one, and often at a parametric rate. A related technique for computing...
