This paper studies the sequential sampling scheme as a solution to the problem of aliasing, where the sampling interval is restricted to a minimum allowable value. Sequential sampling is analyzed and it is proved that when the sampling ratio is an integral number, the associated spectral...

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...

This paper employs the smooth transition autoregressive models (STAR) to analyze Tunisian exchange rate pass-through on quarterly data over the period 2011Q4 2019Q4. The non linearity tests suggest that the LSTAR specification describes better the behavior of exchange rate pass-through in...

This study revisits the issue of mean reversion in the import rice prices of Asian countries over the period between 1995 and 2015. Augmented Dickey Fuller tests with a conventional linear regression model support the presence of a unit root in the levels of the price data. However, when...

This paper discusses the extent and the determinants of the internationalization of European inventive activity, between 1990 and 2004, using an innovative method to treat the information contained in the European Patent Office's Patstat database. The observed level of internationalization of...

In this paper, we compare standard approaches used to handle losses in logarithmic stochastic profit frontier models with a simple novel approach. We discuss discriminatory power, rank stability and precision of profit efficiency scores. Our new method enhances rank stability and discriminatory...

This paper presents empirical evidence to show how socioeconomic factors affect the adoption of and investment in agrochemicals in the cocoa sector of Côte d’Ivoire. The analysis uses primary farm-level data collected in 2002 from a nationally representative sample of more than one thousand...

Sample selection problems are pervasive when working with micro economic models and datasets of individuals, households or firms. During the last three decades, there have been very significant developments in this area of econometrics. Different type of models have been proposed and used in...

Improved household accessibility to credit is identified as a significant determinant of intra-household re-allocation of labour resources with important implications for productivity, income, and poverty status. However, credit accessibility could also have wider impacts on poverty if it leads...

The purpose of this study is to investigate the causal effects of governments’ social distancing measures to curb the spread of the ongoing SARS-COV-2 outbreak on the hotel industry of major tourist destinations (France, Greece, Italy, Spain, Portugal, and Turkey). The empirical analysis...
