Testing For Bid Affiliation In Repeated Second-Price Auctions With Posted Prices, Andreas Drichoutis, Rodolfo M. Nayga, Panagiotis Lazaridis, Beom Su Park Jul 2009

Testing For Bid Affiliation In Repeated Second-Price Auctions With Posted Prices, Andreas Drichoutis, Rodolfo M. Nayga, Panagiotis Lazaridis, Beom Su Park

Andreas Drichoutis

In repeated second-price experimental auctions, the winning bid is normally posted after each round. The posting of these winning prices after each round can result in bids submitted in later rounds to be affiliated with posted prices from earlier rounds. This paper introduces a formal test for bid affiliation in repeated second-price auctions with posted prices using a dynamic panel model. We then apply this test to formally check the presence of bid affiliation effects in three datasets used in previous studies.

Can Nutritional Label Use Influence Body Weight Outcomes?, Andreas Drichoutis, Rodolfo M. Nayga, Panagiotis Lazaridis Jan 2009

Can Nutritional Label Use Influence Body Weight Outcomes?, Andreas Drichoutis, Rodolfo M. Nayga, Panagiotis Lazaridis

Andreas Drichoutis

Nutritional labeling has been of much interest to policy makers and health advocates due to rising obesity trends. So can nutritional label use really help reduce body weight outcomes? This study evaluates the impact of nutritional label use on body weight using the propensity score matching technique. We conducted a series of tests related to variable choice of the propensity score specification, quality of matching indicators, robustness checks, and sensitivity to unobserved heterogeneity using Rosenbaum bounds to validate our propensity score exercise. Our results generally suggest that nutritional label use does not affect body mass index. Implications of our findings ...

Body Weight Outcomes And Food Expenditures Among Older Europeans: A Simultaneous Equation Approach, Andreas C. Drichoutis, Panagiotis Lazaridis, Rodolfo M. Nayga

Andreas Drichoutis

We analyze the inter-relationships between body weight outcomes and food expenditures among older Europeans using a simultaneous equation model. Several statistical tests were conducted to assess endogeneity of selected variables, the exogeneity, relevance, and validity of instruments used, and the identification of the model. Our results generally suggest, contrary to normative views, that food-away-from-home expenditure is negatively related to body mass index (BMI). BMI is negatively related to the percentage of food spent away from home.
