The scientific foundation of dynamic stochastic general equilibrium (DSGE) models

DSGE-models provide a coherent framework of analysis. This coherence is brought about by restricting acceptable behavior of agents to dynamic utility maximization and rational expectations. The problem of the DSGE-models (and more generally of macroeconomic models based on rational expectations) is that they assume extraordinary cognitive capabilities of individual agents. In addition, these models need a lot of ad-hoc assumptions to make them fit the data. I argue that we need models that take into account the limited cognitive abilities of agents. One can introduce rationality in such models by assuming “trial and error“ learning. I propose such a model and I analyze its implications.

George F. Kennan’s Realism

Recent studies of the career diplomat and distinguished historian George F. Kennan, and particularly a little noted intellectual biography by Lee Congdon, reveal a side of this figure that has often been neglected. Despite his reputation as a critic of the Cold War, Kennan was in fact a strong anti-Communist and profoundly conservative thinker. His conventional defenders have stressed his displeasure with vocal anti-Communism in order to create an image of him that is consistent with their left-of-center politics. This has come at the expense of playing down unfashionable opinions that Kennan expressed on a wide range of issues. Many of his opinions, which he viewed as eminently “realistic,” would have been unacceptable to his mainstream admirers even fifty years ago, were it not for his stands on the Cold War and for certain isolated statements drawn from his post-World War Two speeches mentioning racial inequality and industrial waste. What is now being published on Kennan’s life, however, provides a more balanced picture. Congdon and John Lukacs have both offered this necessary corrective to earlier views about their subject in recent biographical studies. These and other commentators are now highlighting the anti-modernist perspective from which he viewed and criticized the twentieth century.

Althusser and the theory of ideology

This paper is a critical discussion of Louis Althusser's text 'Ideology and Ideological State Apparatuses'. It questions the pertinence of the problem of the reproduction of the relations of production. It challenges both parts of Althusser's answer to this problem. The first being the theory of ideological state apparatuses and the second the theory of the formation of individual subjects through the imaginary. The concept of representation is subjected to critical discussion.
