This essay reviews progress in empirical economics since Leamer's (1983) critique. Leamer highlighted the benefits of sensitivity analysis, a procedure in which researchers show how their results change with changes in specification or functional form. Sensitivity analysis has had a salutary but...

In the context of interdependence of the financial markets, it becomes interesting to analyze the implications associated with the Terrorist Attacks of the 11th of September of 2001, in the USA, in terms of the development of contagion mechanisms between the main international stock exchanges....

Using Markov Chain Monte Carlo algorithms within the limited information Bayesian framework, we estimate the parameters of the structural equation of interest and test weak exogeneity in a simultaneous equation model with white noise as well as autocorrelated error terms. A numerical example and...

The common approach to evaluating a model in the structural VAR literature is to compare the impulse responses from structural VARs run on the data to the theoretical impulse responses from the model. The Sims-Cogley-Nason approach instead compares the structural VARs run on the data to...

We apply Purchasing Power Parity (PPP) theory to the analysis of long- run equilibrium in the foreign exchange market. We study the case of Portugal vis-à-vis Germany and Spain, and the case of Spain vis-à-vis Germany, in the period 1960-1990. The empirical analysis was based on unit-root...

Theoretical study identifying one modality with conditions necesary for the financial stabilization of an inherently unstable system; and 5040 other unstable dynamic modes. It draws on knowledge made available by the academic field of Control Engineering.

Inflation is a far from homogeneous phenomenon, but this fact is ignored in most work on consumer price inflation. Using a novel methodology grounded in theory, the ten sub-components of the consumer price index (excluding mortgage interest rates, or CPIX) for South Africa are modeled separately...

This paper analyses the NAIRU making use of a cointegrated VAR and of Italian labour market data. We show that a cointegrated VAR represents a statistically adequate (using Aris Spanos's terminology) approach to the estimation of the NAIRU. This is an effective way to overcome several problems...

The central finding of the recent structural vector autoregression (SVAR) literature with a differenced specification of hours is that technology shocks lead to a fall in hours. Researchers have used this finding to argue that real business cycle models are unpromising. We subject this SVAR...
