Empirical demand analysis is usually conducted on the basis of either ‘regularity’ or ‘flexibility’. This paper takes a middle ground between ‘regularity’ and ‘flexibility’, offering a compromise in the form of a new specification termed ‘REDS’.

This paper identifies a new sufficient condition for a prudent agent to have positive precautionary saving in the presence of labor income and interest rate risks of any size. We also provide three economic interpretations for this condition focusing respectively on the marginal effect of saving...

Three types of demand functions are central to contemporary consumer theory: the Marshallian, the Hicksian, and the Frischian demand functions. This paper presents a systematic definition of the analytical relationships amongst these demand functions under the maintained hypothesis that the...

We introduce an augmented Becker–DeGroot–Marschak mechanism for the revelation of willingness-to-accept and willingness-to-pay in transaction cycles. The mechanism can be used to test for a behavioral anomaly.

We find for logit with income effects a function that generates choice probabilities via Roy’s identity. We show that it possesses all the properties to qualify as an indirect utility, it has a closed-form expression for the practically interesting translog specification of the systematic...

We show that in a unit demand discrete choice framework with at least three goods, demand cannot be additively separable in own price. This result sharpens the analogous result of Jaffe and Weyl (2010) in the case of linear demand and has implications for testing of the discrete choice...

A multiplicative form of the habit term in the utility function has some undesirable properties if the habit function is itself still additive (Wendner, 2003). A geometric form for the way the stock of habit accumulates can resolve these shortcomings.

We show that a steeply increasing workload before a deadline is compatible with time-consistent preferences. The key departure from the literature is that we consider a stochastic environment where success of effort is not guaranteed.

This paper provides, as a counter example to the Alchian–Allen theorem, a theory of Giffen-like goods: a per unit charge to two similar goods raises the relative price of the lower quality good and yet increases the (relative) demand of the good.

In vertically differentiated repair markets with insured customers, insurance coverage increases price level, entry, and the high quality provider’s profits. In the market for pharmaceuticals, this should be taken into account when calculating the extent of patent periods.
