The macroeconomic indicators concern both the flows that are not fully or partially compensated over a time interval, which can be cumulated or integrated, and the stocks or funds identified in a particular moment. These indicators are addressed either as free real and nominal indicators, or as...

La literatura especializada reconoce la existencia de sesgos potenciales en el índice de precios al consumidor. Utilizando índices de precios hedónicos generados por el Bureau of Labor Statistics, el ajuste al precio de los automóviles propuesto por Izquierdo, Licandro y Maydeu (2001), y los...

We review key aspects of forecasting using nonlinear models. Because economic models are typically misspecified, the resulting forecasts provide only an approximation to the best possible forecast. Although it is in principle possible to obtain superior approximations to the optimal forecast...

Although the stability of coefficients from hedonic regressions has received much attention recently, that of dummy variable (DV) price indexes obtained from these regressions has not. In principle, one problem translates into the other only when some prices are not observed in the data....

In this paper, we propose a quantitative measure for inflation expectations based on consumer survey data. Thereafter, we proceed to testing the rationality assumption. This issue is of noteworthy interest in its own as it is commonly assumed in the theoretical modelling literature that the...

Changes in quality in information technology products provoke that compilation of their price indexes represent a major challenge. In this respect, the aims of this study are three. First, to build price indexes for personal computers during 1990-2004. Second, to compare our price indexes with...

The standard theory of reform in applied welfare economics (going back to contributions by e.g. Ramsey, Samuelson...

In 1979, the Danish mathematician Georg Rasch recounted a 1959 visit with his former teacher, and later economics Nobel Prize winner, Ragnar Frisch. At this time, Frisch prompted Rasch to formalize his work in a separability theorem. Previously unnoted is that Frisch's close colleague, Irving...
