This paper provides a general overview of the social, environmental, and economical issues related to biofuels and a review of economic modeling of biofuels. The increasing importance of biofuels is driven primarily by government policies since currently available biofuels are generally not...

This paper uses time-series data from nineteen Latin American countries and the U.S. to test for income convergence using two existing definitions of convergence and a new testable definition of ?-convergence. Only Dominican Republic and Paraguay were found to pair-wise converge according to the...

Neural networks are a computing paradigm developed from artificial intelligence and brain modelling’s fields, which lately has become very popular in business. Many researchers are seeing neural networks systems as solutions to business problems like modelling and forecasting, but...

This paper uses time-series data from nineteen Latin American countries and the U.S. to test for income convergence using two existing definitions of convergence and a new testable definition of β-convergence. Only Dominican Republic and Paraguay were found to pair-wise converge according to...

The evolution over time of subjective well-being (SWB) in transition countries exhibit some peculiarities: greater variations which are more strongly correlated with the trends of GDP relative to other countries. What is the possible role of social trust in predicting such variations? We compare...

What does predict the evolution over time of subjective well-being? We answer this question correlating cross country time series of subjective well-being with the time series of social capital and/or GDP. First, we adopt a bivariate methodology similar to the one used used by Stevenson and...

I present evidence that higher frequency measures of inflation expectations outperform lower frequency measures of inflation expectations in tests of accuracy, predictive power, and rationality. For decades, the academic literature has focused on three survey measures of expected inflation: the...
