We consider a sequential equilibrium model over two periods, during the first of which agents have perfect information and their expectations are formed as if there were complete future markets. We show that, in the second period, equilibrium prices may well be different from those expected,...

Since the late 1960s, research in the field of general equilibrium theory has focused on economies in which spot markets for commodities coexist with some asset markets and trade takes place sequentially over time. The study of ‘sequential economies’ has developed along two paths inspired by...

Since the late 1960s, the efforts of general equilibrium theorists have been directed towards overcoming the evident limitation of the Arrow-Debreu model, i.e. the assumption that the transactions associated with the future activities of agents are all regulated at the initial date on a complete...

We consider a sequential equilibrium model over two periods, during the first of which agents have perfect information and their expectations are formed as if there were complete future markets. We show that, in the second period, equilibrium prices may well be different from those expected,...

This paper is aimed at discussing Mandler's interpretation of Sraffa's price theory. In particular we will analyse Mandler's idea that an institutional determination of distribution, suggested by Sraffa, could be solidly advanced only in the case of equilibrium price indeterminacy in...

The theory of value has been based ever since Adam Smith on the idea that the market prices of commodities, those at which actual trade takes place, gravitate around a central position known as natural prices. This paper seeks to develop a statistical idea of the process in question and suggests...

Malinvaud (2003) observed that once techniques are ranked according to Hick’s concept of average period for a given rate of interest, a rise in the latter entails the use of a technique with a shorter average period. After a reconstruction of Malinvaud’s argument, it is shown that the result...
