Social scientists are often interested in assessing relative changes between two groups over time, for example, the convergence of black-white wages from 1940 to 1990. In such situations, we need a control group for both treatment groups to remove biases resulting from time trends and unobserved...

This paper examines the effects of working time reduction policy on labour supply (hours of work and whether an individual takes a second job) and household production, by exploiting the Chinese Two-Day Weekend Policy, which effectively reduced weekly working days from six to five in May 1995,...

This paper empirically analyzes the impact of Chinese minimum wage regulations on the firm decision to invest in physical and human capital. We exploit the geographical and inter-temporal variations of county-level minimum wages in a panel data set of all state-owned and all above-scale...

Job search procedures are a form of human capital investment in that they involve current investments to enhance future returns, analogous to human capital investments in areas such as education, training and mobility that yield future returns. While the theoretical and empirical literature on...

The minimum wage has been regarded as an important element of public policy for reducing poverty and inequality. Increasing the minimum wage is supposed to raise earnings for millions of low-wage workers and therefore lower earnings inequality. However, there is no consensus in the existing...

This study uses migrant household survey data from 2008 and 2009 to examine how parental migration decisions are associated with the nutritional status of children in rural and urban China. Results from instrumental variables regressions show a substantial adverse effect of children's exposure...

We use several datasets to study whether son preference prevails in the human capital investment among Chinese rural-urban migrant households. We find that son preference exists among the rural migrants' households and that it caused lower probabilities relative to that of their boy counterparts...

The theory of fiscal and regulatory competition between jurisdictions is more advanced than its empirical testing. This is particularly true of labor regulation in general, and minimum wage regulation in particular, and especially so for developing countries. This paper utilizes the spatial lag...

In the book Myth and Measurement, Card and Krueger (1995) examine the economic impact of the 1989 minimum wage hike on the welfare of 110 firms which employ a disproportionate number of minimum-wage workers. Their results show mixed evidence that excess returns associated with news about the...

We present a theorem helpful in estimating the mean and variance of a linear function with arbitrary multivariate randomness in its coefficients and variables. We derive a generalized decomposition result from two random linear functions in which the result can be applied to most models using...
