A product is called technically inefficient when it has higher price and/or lower quality than others. Technical inefficiency of product has been conceptualized since Lancaster (1966), and empirically measured by many researchers, for example, Fernandez-Castro and Smith (2002) and Lee et al....

Matched sampling is a methodology used to estimate treatment effects. A caliper mechanism is used to achieve better similarity among matched pairs. We investigate finite sample properties of matching with calipers and propose a slight modification to the existing mechanism. The simulation study...

A caliper mechanism is a common tool used to prevent from inexact matches. The existing literature discusses asymptotic properties of matching with caliper. In this simulation study we investigate properties in small and medium sized samples. We show that caliper causes a significant bias of the...

El presente trabajo analiza el empleo del ferrocarril por parte de las empresas gallegas que transaccionan con operadores del Norte de Portugal. Demostramos el uso residual de dicha infraestructura (0,01% de las transacciones totales) frente al empleo masivo del camión, determinamos factores...

This study extends a test for the presence of binding zoning, originally developed to be applied across many adjacent jurisdictions, so that it can be applied within a single jurisdiction. This study also demonstrates how to carry out this test in the presence of spatially correlated OLS...

In this paper I investigate response bias in survey data on annual driving mileage and evaluate the performance of a proposed remedy, Orbit. Individuals systematically exaggerate their deviation from the sample average, and using the self-reported data leads to misleading estimates of the income...
