Moreover, panel data on the network have until recently only rarely been available, so the majority of methods focus on the case with a single cross section of data2.
This paper reviews recent developments in methods to identify linear peer effect models using networks data data with detailed information on the exact interactions between agents when a single cross section of data is available.
We have a single cross section of 3,133 counties, to which we add a second level to the model by including state-level factors describing nurse practitioner laws, shortages of medical doctors ( MDs), prevalence of MediGap insurance among persons aged 65+, state insurance market competition, and two insurance regulatory factors.
Identification in their model comes entirely from the structure that they impose and the non-linear budget constraints that individuals face in their single cross section of data.
In this paper, we provide an overview of methods to identify social effects in linear social effect models using a single cross section of data.
As discussed in Borjas (1985), assimilation profiles from a single cross section of data will give misleading results if either immigrant selection on unobservables varies by arrival cohort or there is selective return migration.
(i, j) Plots of the path of a center of mass along a single cross-section of the projections for the two alignment methods.
At about the same time, an investigation of different reinforcement concepts for the ship and/or its support cradle was undertaken and different simple finite element (FE) models were also constructed for single cross-sections of the hull to predict future deformation and structural behaviour for different support scenarios [9, 10].
A number of immunoreactive profiles were visible in single cross-sections of the cartridge, but the slender axon size Drosophila lamina cells gave some uncertainty in the exact determination of which profiles were axons and which dendrites.
Our model was based on a single cross section at the level of the lesser trochanter, not taking into account differences in the cross-sectional shape of other parts of the implants.
Because the resolution was too high to fit any single cross section into a single image, we used the tiling function of the microscope to fuse 1024 × 1024 pixel subpanels into single images for each cross section.
