In empirical regional economics, returns to scale are typically estimated at the regional level in search for evidence on alternative theories of growth and agglomeration. However, returns to scale may also have a firm-level dimension. In this paper, we exploit micro level data and estimate the...

In the growth literature, researchers are typically concerned with macro convergence. However, to the extent that macro dynamics result from the underlying microeconomic relations, convergence should also be investigated at the micro-level. In this paper, we suggest an approach that allows...

This study considers how firms’ internal variables and regional factors affect the total factor productivity of Italian manufacturing firms. Due to of the hierarchical structure of data in estimation, we employ a multilevel model. Results, which refer to 2006, show the importance of...

The calibration of probability or confidence judgments concerns the association between the judgments and some estimate of the correct probabilities of events. Researchers rely on estimates using relative frequencies computed by aggregating data over observations. We show that this approach...

Spatial econometrics has been criticized by some economists because some model specifications have been driven by data-analytic considerations rather than having a firm foundation in economic theory. In particular this applies to the so-called W matrix, which is integral to the structure of...

Cross-country comparisons of costs and quality between hospitals are often made at the macro level. The goal of this study was to explore methods to compare micro‐level data from hospitals in different health care systems. To do so, we developed a multi‐level framework in combination with a...
