The paper lists salient characteristics of the certainty theory of consumer choice and discusses the import of prominent empirical analyses of the theory. All of them reject the theory's empirical relevance which suggests that the theory is unfit to analyze consumer choice in an uncertain world....

By representing a system of budget shares as an approximate factor model we determine its rank, i.e. the number of common functional forms, or factors, spanning the space of Engel curves. Once the common factors are estimated via approximate principal components, we identify them by imposing...

The mixed-demand model allows for very flexible specification of what should be considered endogenous and exogenous in demand system estimation. This paper introduces a revealed preference framework to analyze the mixed-demand model. The proposed methods can be used to test whether observed data...

Existing estimation methods for multi-factor CES functions require limiting assumptions about the nature of technical change. We demonstrate how a system of equations and a fixed elasticity in the nested process can provide identification for more flexible specifications and for small data...

This paper uses the Fourier flexible form to jointly approximate utility and service flows from durable and nondurable goods. In contrast, parametric functions are usually not flexible enough to accurately approximate nonseparability and often give inconsistent results. This paper calls these...

This chapter presents a unified set of estimation methods for fitting a rich array of models describing dynamic relationships within a longitudinal data setting. The discussion surveys approaches for characterizing the micro dynamics of continuous dependent variables both over time and across...

This paper proposes a generalization of the nonlinear simultaneous equation model of Pesaran and Pick (2007) by modelling the comovement between the two endogenous variables as a smooth function of the magnitude of the endogenous variable rather than a step function. The threshold and the speed...

Border effects can have a considerable influence on the effectiveness of excise tax policy measures. The opportunity to buy taxable goods in the nearest lower-tax state redistributes the tax burden among consumers and determines the treatment intensity of how an increase in the tax rate may...

We estimate the effect of information on consumers' willingness to pay for branded goods in physically homogeneous consumer packaged goods categories. In a case study of headache remedies, we find that college education, working in a healthcare occupation, and other proxies for product knowledge...
