Moschini, GianCarlo. 
The notion of indirect separability is exploited to derive a new multistage demand system. The model allows a consistent parameterization of demand relations at various budgeting stages and it fulfills the requirement of flexibility while satisfying separability globally. Two propositions are derived to characterize flexible and separable functional forms, which lead to the specification of a flexible and separable translog (FAST) demand system. The model is particularly attractive for modeling large complete demand systems, and is illustrated with an application to Canadian food demand.

Brosig, Stephan. 
The paper describes a two stage model of Hungarian households' food demand. Demand for the food aggregate is represented by a WorkingLeser type single equation model while demand for seven distinct food types is modelled in a complete demand system using the LA/AIDS functional form. Estimation is based on household budget survey data for 1996. Demand elasticities are estimated for average households as well as for specific groups defined by sociodemographic characteristics. Fruit and vegetables are found to be the food types with most elastic demand but in general, differences between elasticities for different products as well as between different sociodemographic groups are relatively small.

Staus, Alexander. 
This article analyses dealer satisfaction data in the agricultural technology market in Germany. The dealers could rate their suppliers in the ’overall satisfaction’ and in 38 questions which can be summarized in 8 dimensions. An ordinal regression model which is also known as the proportional odds model is used to analyse the ordinal scaled rating of the dealers. The ordinal regression model is a well examined method in econometric theory, but many authors prefer using a linear regression model due to better interpretation, even the assumptions of a linear regression do not fit the data. Since the estimated coefficients of an ordinal regression model can not be properly interpreted we show other methods for a better insight of the relationship of the...

Lin, Ni; Shumway, C. Richard. 
The sensitivity of asset fixity conclusions, input adjustment rates, and elasticities to choice of functional form is examined using a dynamic dual model of U.S. agriculture. A very general initial specification allows tests of instantaneous adjustment to be performed for every input. Test results are mixed across functional forms for all inputs except real estate, which is consistently found to be quasifixed. Important differences in estimated adjustment rates and elasticities are also found among the functional forms. The translog has higher likelihood support than either the generalized Leontief or normalized quadratic functional forms for this dynamic model specification and data set.

Merlo, Antonio. 
In this paper we structurally estimate a gametheoretic model of government formation in a multiparty parliamentary democracy. We focus on the timing and the terms of government agreements in the context of a multilateral stochastic model of sequential bargaining with complete information (Merlo and Wilson (1194, 1995)) where efficient delays may occur in the unique equilibrium. Besides showing that our model yields a good fit to the data on the duration of negotiations over government formation as well as government durations in postwar Italy, we use our estimates to quantify the advantage to proposing and to conduct policy experiments to evaluate the effects of changes in the bargaining procedure. We show that the gains from proposing tend to be quite...
