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...

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...

One of the foundations of the labour theory of value used by Ricardo in the Principles is that rent does not enter into commodity prices. In response to objections raised by Malthus and Say, Ricardo defended this idea by arguing that even where all cultivated land pays rent, the last dose of...
