MEASURING PRODUCTIVITY

Abstract Quantifying productivity is a conditio sine qua non for empirical analysis in a number of research fields. The identification of the measure that best fits with the specific goals, as well as being data driven, is currently complicated by the fact that an array of methodologies is available. This paper provides economic researchers with an up‐to‐date overview of issues and relevant solutions associated with this choice. Methods of productivity measurement are surveyed and classified according to three main criteria: (i) macro/micro; (ii) frontier/non‐frontier and (iii) deterministic/econometric.     

Price Indices Based on the Hedonic Repeat-Sales Method: Application to the Housing Market

Shiller (1993) proposes the hedonic repeated-measures (HRM) approach to measuring constant quality price indices for heterogeneous assets such as some bonds and real estate. We derive a mathematical relationship between the coefficients of the HRM model and those from the standard repeat-sales model, and we demonstrate how hedonic characteristics should be chosen for inclusion in the HRM model. Empirical estimates using Fairfax, Virginia, housing transactions data show that the HRM price index evaluated at the mean of the hedonic variable is virtually identical to the standard repeat sales index, just as predicted by our mathematical relationship. But the HRM allows estimation of different price paths for heterogeneous assets. We demonstrate that use of assessed value as the only hedonic characteristic allows parsimonious HRM estimates.     

Do emotions matter? Coherent preferences under anchoring and emotional effects

Emotions can affect individuals' preferences and economic behavior. In this paper we consider the relationship between emotions and anchoring effects in non-market valuation. The findings show that although anchoring effects are relevant, elicited preferences are coherent, in the sense that they are sensitive to changes in the dimension of the good. Additionally, it is found that the relationship between emotional intensity and the level of anchoring is U-shaped, with anchoring declining as emotional intensity rises until a minimum is reached. Thus, preferences can be substantially less affected by anchoring effects if emotional intensity deviates from extreme values. Finally, it is found that the degree of sensitivity to scope is influenced by the level of emotional load involve in the valuation task.
