The market for resident domestic helpers offers a rare opportunity where the surplus from employment relationship can be quantitatively measured for each individual employee. Using the difference between employer's cost of time and employee's wage as a measure of rent, it is found that wages for...

In an assignment market with uncertainty regarding productive ability of participants, early contracting can occur as participants balance risk sharing and sorting efficiency. More promising agents may contract early with each other because insurance gains outweigh sorting inefficiency, whereas...

Using ordinary calculus techniques, we investigate the conditions under which LeChatelier effects are signable for finite changes in parameter values. We show, for example, that the short run demand for a factor is always less responsive to price changes than the long run demand, provided that...

This paper provides an overview of retirement patterns in Hong Kong on the basis of limited data. A censored regression model is used to infer the retirement age from people`s current retirement status and their current age. This model is equivalent to a restricted probit model, and the...

This paper presents a new method of estimating the effects of immigration on the labor market that does not require variations in immigration across cities. With a two-stage CES model that aggregates immigrant groups by age cohorts and aggregates cohorts into effective labor, the econometric...

We present a model of delegation with self-interested and privately informed experts. A team of experts with extreme but opposite biases is acceptable to a wide range of decision makers with diverse preferences, but the value of expertise from such a team is low. A decision maker wants to...

This paper discusses the implications of rationing by waiting when consumers have different time costs and personal valuation. The joint distribution function of time costs and personal valuations is used to characterize market equilibrium. It is argued that, under certain conditions, an...

Committees improve decisions by pooling members' independent information, but promote manipulation, obfuscation, and exaggeration of private information when members have conflicting preferences. Committee decision procedures transform continuous data into ordered ranks through voting. This...

Though individuals prefer to join groups with high quality peers, there are advantages to being high up in the pecking order within a group if higher ranked members of a group have greater access to the group's resources. When two organizations try to attract members from a fixed population of...

When employers cannot tell whether a school truly has many good students or just gives easy grades, schools have an incentive to inflate grades to help mediocre students, despite concerns about preserving the value of good grades for good students. We construct a signaling model where grades are...
