Over the past two decades, hundreds of stated preference studies have been conducted in less-developed countries. This article examines what has been learned on the methodological front from stated preference research, and it summarizes the empirical evidence from stated preference studies about household preferences in lessdeveloped countries. The main conclusion is that households’ willingnes...

Credence goods markets are subject to failure because consumers are unable to punish fraudulent experts who diagnose and supply treatment, and they lack the technical expertise with which to verify the quality of treatment actually offered. The focus of research in agricultural economics has been almost entirely on how labeling and certification of food products that contain credence attributes...

Around the globe and starting in the affluent West, women have made major, even revolutionary, strides toward equality with men. However, while access to major social institutions has equalized dramatically, expanded participation in labor markets and educational systems often comes in the form of gender-differentiated roles within these institutions. This article reviews international trends o...

The remarkable kinetic slowdown experienced by liquids as they are cooled toward their glass transition is not accompanied by any obvious structural change. Understanding the origin of this behavior is a major scientific challenge. At present, this area of condensed matter theory is characterized by an abundance of divergent viewpoints that attempt to describe well-defined physical phenomena. W...

The quantification of three-dimensional (3D) flow structures and particle dynamics is crucial for unveiling complex interactions in turbulent flows. This review summarizes recent advances in volumetric particle detection and 3D flow velocimetry involving holography. We introduce the fundamental principle of holography and discuss the debilitating depth-of-focus problem, along with methods that ...

This paper discusses both the opportunities for and the challenges associated with integrating economics and ecology in the study of ecosystem services. We distinguish between integration in positive versus normative analysis. There is rapid growth in positive research that combines the two disciplines to provide insight and better understanding of the bidirectional linkage between economic and...

Squamate reptiles (lizards and snakes) are a diverse clade in which there appears to have been multiple origins of many remarkable traits, including: (a) parthenogenetic reproduction, (b) viviparity, (c) snake-like, limb-reduced body form, (d ) herbivory, and (e) venom. These repeated transitions make squamates an outstanding/excellent system for addressingmany fundamental questions in evolutio...
