An incomplete manuscript on Statistics for economists.

The purpose of this paper is twofold: 1) to highlight the widely ignored but fundamental problem of ‘superpopulations’ for the use of inferential statistics in development studies. We do not to dwell on this problem however as it has been sufficiently discussed in older papers by...

The present work corroborates the existence of two anomalies that question the hypothesis of efficient markets in the Chilean stock market, these are the “effect weekend” or “effect monday” and the “effect month end”. Using the daily values of closing of stock-exchange index IPSA,...

For decades, the academic literature has focused on three survey measures of expected inflation: the Livingston Survey, the Survey of Professional Forecasters, and the Michigan Survey. While these measures have been useful in developing models of forecasting inflation, the data are low frequency...

We conduct a Monte Carlo study of the global regularity properties of the Normalized Quadratic model. We particularly investigate monotonicity violations, as well as the performance of methods of locally and globally imposing curvature. We find that monotonicity violations are especially likely...

We examine the accuracy of survey-based expectations of the Chilean exchange rate relative to the US dollar. Our out-of-sample analysis reveals that survey-based forecasts outperform the Driftless Random Walk (DRW) in terms of Mean Squared Prediction Error at several forecasting horizons. This...

In this study, we compare the Hodrick-Prescott Filter technique concerning the Fractional filtering technique, which has recently started to be used in various applied sciences, i.e., physics, engineering, and biology. We apply these filtering techniques to the quarterly GDP data of Turkey,...

In this paper we show that the exchange rates of some commodity exporter countries have the ability to predict the price of spot and future contracts of aluminum. This is shown with both in-sample and out-of-sample analyses. The theoretical underpinning of these results relies on the...
