This paper uses annual US data to examine the causal relationship between immigration and real GDP. Despite its implications for policy, a statistically robust relationship between these two series has been difficult to pin down. Our tests reveal that both the series are break-stationary....

This paper estimates the unconditional and conditional linear dependence between exogenous supply (R&D), endogenous demand (prices) and TFP based on the linear feedback method. Unit root tests are performed for Nebraska agriculture sector data spread over 1936-94 time period. Results indicate...

Using daily data from 182 spatially separated U.S. cash markets for the years 2006-2011, I investigate price discovery for corn. With a large number of cash markets available, I take into account explicitly the issue of market selection, which has been neglected in previous work. I find that...

This study investigates dynamic relationships among U.S. corn cash prices for the years 2006-2011. With daily data from 182 spatially separated markets spreading across 7 states, Iowa (IA), Illinois (IL), Indiana (IN), Ohio (OH), Minnesota (MN), Nebraska (NE), and Kansas (KS), we apply an error...

In this paper the dynamic information flows among monthly prices of agricultural commodities in the United States (U.S.) and Mexico for the years 2000-2012 are analysed. Error correction models and directed acyclical graphs are employed with observational data to identify the dynamic...
