- Information sharing and credit : firm-level evidence from transition countries (2008)
- We investigate whether information sharing among banks has affected credit market performance in the transition countries of Eastern Europe and the former Soviet Union, using a large sample of firm-level data. Our estimates show that information sharing is associated with improved availability and lower cost of credit to firms. This correlation is stronger for opaque firms than transparent ones and stronger in countries with weak legal environments than in those with strong legal environments. In cross-sectional estimates, we control for variation in country-level aggregate variables that may affect credit, by examining the differential impact of information sharing across firm types. In panel estimates, we also control for the presence of unobserved heterogeneity at the firm level, as well as for changes in macroeconomic variables and the legal environment.

- Four undescribed Oligocene craneflies from Florissant, Colorado, (Diptera: Tipulidae) (1985)
- The following described craneflies were discovered during ongoing research at the Museum of the University of Colorado in preparation of parts of the Colorado Natural History Inventory. These Oligocene shale specimens are somewhat difficult to study. This is especially true of Limoniinae with lightly sclerotized veins. With proper illumination and a good binocular microscope, the veins often appear as glittering lines on the shale. The veins often are better seen when the specimen is placed so the veins are illuminated from one end. Sometimes the shale is so rough that this lighting does not improve their visibility. The help of Dr. George W. Byers of University of Kansas was immeasurable during the preparation of this manuscript. He not only verified, or suggested, generic assignment but also prepared the illustrations of venation. Mrs. Grace H. Kemper, as usual, helped with measurements and processing of the manuscript.
- Lithoserix williamsi (Siricidae: Hymenoptera) a newly recognized fossil horntail from Florissant, Colorado (1986)
- A recently found fossil from the old Scudder pit (?) appears to be a large female horntail. It shows the ventral aspect. Compared with modern Siricidae, the length of its ovipositor in relation to the body proper suggests modern Xeris spectrum. Unfortunately the venation is incompletely preserved on both wings. In addition to this the forewings and hindwings overlap to some extent on each side. What venation is decipherable is seen in the two sketches. It does not seem to agree with any of the modern genera examined but approaches that of Sirex more closely than any other. Both antennae are faintly indicated. They are stout, many-segmented and in keeping with those of Siricidae. Both hind legs are preserved faintly almost throughout their length. They are stout, and the individual segments are clearly defined.
