This paper assesses the relative efficiency of knowledge production in the OECD using a nonparametric DEA approach. Resources allocated to R&D are limited and should therefore be used efficiently given the institutional and legal constraints. This paper presents efficiency scores based on an...

This paper constructs estimators for panel data regression models with individual specific heterogeneity and two-sided censoring and truncation. Following Powell (1986) the estimation strategy is based on moment conditions constructed from re-censored or re-truncated residuals. While these...

The objective of our study was to evaluate the efficiency of public, private for-profit, and private non-profit hospitals in Germany. First, bootstrapped data envelopment analysis (DEA) was used to evaluate the efficiency of a panel (n = 1,046) of public, private for-profit, and private...

This paper investigates the biological standard of living toward the end of Spanish rule. We investigate levels, trends, and determinants of physical stature from the birth cohorts of the 1860s to the 1890s using data on 23,000 Filipino soldiers enlisted by the U.S. military between 1901 and...

Many estimation methods of truncated and censored regression models such as the maximum likelihood and symmetrically censored least squares (SCLS) are sensitive to outliers and data contamination as we document. Therefore, we propose a semipara- metric general trimmed estimator (GTE) of...

We investigate the effects of incorporating a fixed input on equilibrium profits and biomass. We first set up a theoretical model with an input that is fixed in the short-run (vessel size) but that can be used with a variable input at suboptimal capacity. We use this model to get predictions for...

This study sheds light on how study specific-characteristics impact mean technical efficiency (MTE) in Nigerian agriculture. Also the paper extracts consensus message about MTE and its drivers in Nigerian agriculture based on studies covering the period 1999-2008. A meta-analysis using truncated...

This study investigates the Cup of Excellence coffee auctions and explains with behavioral economics observed intransitives in choice sets. Buyers are selecting lower quality coffees and paying higher prices for these coffees because they receive a higher rank. The estimates suggest that the...
