Heterogenität von Umweltbedingungen gilt als einer der wichtigsten Faktoren für die Verteilung von Artenreichtum weltweit. Laut der Habitatheterogenität-Hypothese bieten räumlich heterogenere Gebiete eine höhere Vielfalt an Umweltparametern und weisen mehr Refugien und Möglichkeiten zur...

Using the Health and Retirement Survey and standard wage decomposition techniques, this paper finds that the difference in intermittent labor force participation between men and women accounts for 47 percent of the contribution to the wage gap of differences in observed characteristics. Not...

Using 1990, 2000 censuses and a 2010 survey, I examine the economic performance of ethnically Chinese immigrants from mainland China, Hong Kong and Taiwan (CHT) in the U.S. labor market. Since 1990, relative wages of CHT migrants have been escalating in contrast to other immigrants. I show these...

Using normalized regression equations, we propose an alternative estimator of industrial gender wage gaps which is identified in the sense that it is invariant to the choice of an unobserved non-discriminatory wage structure, and to the choice of the reference groups of any categorical...

Using a monthly survey, this paper finds that supporters of the governing cabinet are significantly happier than non-supporters throughout our sample period. We investigate the reason and examine two hypotheses: 1) happy persons support the ruling Liberal Democratic Party, and 2) supporters of...

A population’s weight conditioned on height reflects its current net nutrition and demonstrates health variation during economic development. This study builds on the use of weight as a measure for current net nutrition and uses a difference-in-decompositions technique to illustrate how black...

We use a set of biomarkers to measure inequality of opportunity (IOp) in health in the UK. Applying a direct ex ante IOp approach, we find that inequalities in health attributed to circumstances account for a non-trivial part of the total health variation. For example, observed circumstances...

Using data from five waves of the Vietnam Household Living Standard Survey, we find evidence of significant urban-rural expenditure inequality. Urban-rural inequality in Vietnam increased dramatically from 1993 to 1998, and peaked in 2002 before reducing slightly in 2004, and significantly in...
