The hedonic model of Rosen (1974) has become a workhorse for valuing the characteristics of differentiated products despite a number of well-documented econometric problems, including a source of endogeneity that has proven difficult to overcome. Here we outline a simple, likelihood-based...

One of the primary motivations behind the establishment of noncontributory pension programs is to allow beneficiaries to retire from the labor force. Yet, as with other unconditional cash transfer schemes, their aggregate effects may be more complex. Using panel data and instrumental variable...

Many researchers use the G-index or E-index to measure firms' takeover defenses. Others argue that these indices are not related to firms' takeover likelihoods. We find that, unlike their raw values, the instrumented versions of these indices are significantly and negatively related to...

A survey of 255 papers that rely on the instrumental variable (IV) approach for identifying causal effects published in the "Big Three" finance journals reveals that IV estimates are larger than their corresponding uninstrumented estimates in about 80% of the studies, regardless of whether the...

We derive nonparametric sharp bounds on average treatment effects with an instrumental variable (IV) and use them to evaluate the effectiveness of the Job Corps training program for disadvantaged youth. We focus on the population average treatment effect (ATE) and the average treatment effect on...

"Statistical adequacy" is an important prerequisite for securing reliable inference in empirical modelling. This paper argues for more emphasis on replication that specifically assesses whether the results reported in empirical studies are based on statistically adequate models, i.e., models...

This paper is the first to use the method of instrumental variables to estimate the causal impact of youth obesity on U.S. medical care costs. We examine data from the Medical Expenditure Panel Survey for 2001-2013 and instrument for child BMI using the BMI of the child's biological mother. IV...
