Governing the simultaneous propagation of N fields in optical fibers and plasmas, the inhomogeneous N-coupled nonlinear Schrödinger equations are, with symbolic computation, analytically investigated in this paper. As one of the important integrable properties, the explicit one- and...

Purpose – The purpose of this paper is to assess how spatial heterogeneity and production diversification have affected the efficiency of households participating in the SLCP. Design/methodology/approach – Based on household survey data collected from three sample counties in the Loess...

For years, anecdotal evidence has suggested increased fertility rates resulting from catastrophic events in an area. In this paper, we measure this fertility effect using storm advisory data and fertility data for the Atlantic and Gulf Coast counties of the United States. We find that...

One of the most notable social phenomena in China is the large urban-rural disparity. There are many studies of it, but most of them focus on income or earnings inequality. In this paper, we investigate the consumption disparity between urban and rural households in China from 1988 to 2002. Our...

This paper is one of the first comprehensive attempts to compare earnings in urban China and India over the recent period. While both economies have grown considerably, we illustrate significant cross-country differences in wage growth since the late 1980s. For this purpose, we make use of...

This paper identifies health determinants in urban China applying Grossman model. Using wave of China Health and Nutrition Survey in 2000, we find that education has important positive effect on health, and cost of health care services has significantly negative impact. However, effects of wage...

This paper assesses the dynamics of treatment effects arising from variation in the duration of training. We use German administrative data that have the extraordinary feature that the amount of treatment varies continuously from 10 days to 395 days (i.e. 13 months). This feature allows us to...

This paper studies the role of training vouchers and caseworkers in public training programs. Using a rich administrative data set, we apply matching and regression methods to measure the effect of the Hartz reform in Germany, which introduced training vouchers and imposed more selective...
