The paper analyses the variability of labour incomes in Argentina from mid-eighties to 2005. The magnitude of the income-instability phenomenon is estimated and its determinants are evaluated under different macroeconomic contexts. The document also analyses how income fluctuations have affected the inequality of income distribution. Finally, the income convergence hypothesis is explored. Data ...

This paper introduces and discusses an heuristic model meant to clarify why and how economic instability may play a crucial role in a modern sophisticated monetary economy. In this model economic instability is specified in terms of structural instability rather than in the usual terms of dynamic instability. This different view of instability implies a different approach to the analysis of the...

Estimates of the effect of different international monetary regimes on the parameters of the Phillips curve, the Keynesian consumption function, and other reduced-form macroeconomic relationships are given. The estimates provide a quantitative assessment of the importance of the Lucas critique for such regime shifts. The estimates are calculated by stochastically simulating an estimated multico...

In this paper we examine a variation on Kaldor’s (1940) model of the business cycle using some of the methods of catastrophe theory. (Thom (1975), Zeeman (1977)). The development proceeds in several stages. Section I provides a brief outline of catastrophe theory, while Section II applies some of these techniques to a simple macroeconomic model. This model yields, as a special case, Kaldor’s bu...
