Monetary policy objectives and targets are not necessarily constant over time. The regime-switching literature has typically analyzed and interpreted changes in policymakers’ behavior through simple interest rate rules. This paper analyzes policy regime-switches by explicitly modeling policymakers’ behavior and objectives. We show that changes in the parameters of simple rules do not necessaril...

metabonomics and other “omics” fields are essential science in analytical chemistry. modern analytical instruments such as proton nuclear magnetic resonance ( 1 h nmr) can be provided the great quantity of analytical information. in order to assign unknown samples, chemometrics methods recognition build classification model based on experimental data.  firstly some current strategies for regard...

Following an analysis of the relation between a standard Steindlian model of stagnation and Steindl’s own analysis, we modify the standard model by introducing endogenous changes in the markup and a reformulation of the investment function. These extensions, which address significant weaknesses of the standard model, find support in Steindl’s writing and leave intact some of Steindl’s key resul...

This paper provides new evidence that estimates obtained from aggregated data may not provide reliable estimates of average firm-level parameters, if the composition of producers with different levels of productivity changes over the business cycle. I examine plant-level data and show that, due to the countercyclical reallocation of output among heterogenous plants, productivity measures based ...

This paper investigates the effects of fiscal policy on the trade balance using a structural factor model. A fiscal policy shock worsens the trade balance and produces an appreciation of the domestic currency but the effects are quantitatively small. The findings match the theoretical predictions of the standard Mundell-Fleming model, although fiscal policy should not be considered one of the m...

Structuralist and post Keynesian models differ in their assumptions about firms’ investment behavior and pricing/output decisions. This paper compares three benchmark models: Kaleckian, Robinsonian and Kaldorian. We analyze the implications of these models for the steady growth path and the cyclical properties of the economy, and evaluate the consistency of the theoretical predictions with empi...

This paper analyzes a model in which the risk associated with entrepreneurial activity implies that the amount of such activity is procyclical and results in amplification and intertemporal propagation of productivity shocks. In the model risk averse agents choose between a riskless project and a risky project with higher expected output (‘the entrepreneurial activity’). Agents who become entre...
