The paper provides a careful, analytical account of Trygve Haavelmo's unsystematic, but important, use of the analogy between controlled experiments common in the natural sciences and econometric techniques. The experimental analogy forms the linchpin of the methodology for passive observation...

Some key econometric concepts and problems addressed by Trygve Haavelmo and Ragnar Frisch are discussed within the general framework of a cointegrated VAR. The focus is on problems typical of time series data such as multicollinearity, spurious correlation and regression results, time dependent...

An explication of the key ideas behind the Cointegrated Vector Autoregression Approach. The CVAR approach is related to Haavelmo’s famous “Probability Approach in Econometrics” (1944). It insists on careful stochastic specification as a necessary groundwork for econometric inference and...

Recent studies have tested the preference axioms of completeness and transitivity, and have detected other preference phenomena such as unstability, learning- and tiredness effects, ordering effects and dominance, in stated preference discrete choice experiments. However, it has not been...

The cointegrated VAR model is proposed as an empirically coherent framework for analyzing macroeconomic phenomena within a dynamic system of pulling and pushing forces. As an illustration we show how an economic theory for inflation and money demand gives rise to a number of hypotheses...

There is widespread evidence that monetary policy exerts asymmetric effects on output over contractions and expansions in economic activity, while price responses display no sizeable asymmetry. To rationalize these facts we develop a dynamic general equilibrium model where households' utility...

We present some simple utility functions whose Marshallian demand functions possess the Giffen property: at some price-wealth pairs, the demand for a good marginally increases in response to an increase in its own price. The utility functions satisfy standard preference properties throughout the...

We consider a pure exchange economy with private ownership in which consumers have interdependent preferences. Hence, consumers’ preferences are defined on the states of the economy. In a Walras equilibrium for such an economy, it may, of course, be possible for two or more consumers to...

This paper provides an introduction to and discussion of the application of lattice-theoretic methods to classic problems in consumer theory. General characterizations of income effects with two goods, and with an arbitrary number of goods, as well as examples of comparative statics over...

In order to model the concept of behavioral heterogeneity, some authors have employed the following approach. By using affine transformations of the price space, a consumption sector is defined as the set of all transformed demand functions of a given "generating" demand function. This leads to...
