Long-run trends or short-run fluctuations : what establishes the correlation between oil and food prices?
Krätschell, Karoline; Schmidt, Torsten - 2012
In this paper we use the frequency domain Granger causality test of Breitung/Candelon (2006) to analyse short- and long-run causality between energy prices and prices of food commodities. We find that the oil price Granger causes all the considered food prices. However, when controlling for...

Herrerias, M.J.; Ordóñez, J. - In: International Review of Economics & Finance 31 (2014) C, pp. 159-170
In this paper we analyze the extent to which the US economy affects international business fluctuations across countries and we ask whether the nonlinear nature of the business cycle affects the degree of co-movement between countries. A multivariate nonlinear LSTAR model is estimated for the...

Productivity-Enhancing Demand Shocks : Evidence from the U.S. Ethanol Boom
Kneller, Richard - 2014
This paper examines the effect of demand on productivity. We exploit the Energy Policy Act of 2005 as a natural experiment which generated plausibly exogenous variation in the capacity of ethanol plants to establish the causal effect of demand on productivity within the corn sector. Using...

Production delays, technology choice and cyclical cobweb dynamics
Dieci, Roberto; Mignot, Sarah; Westerhoff, Frank H. - 2021
We develop a cobweb model in which firms, facing a two-period production delay, have access to a flexible (costly) and an inflexible (cheap) production technology. Moreover, firms select between production technologies depending on theirevolutionary fitness, measured in terms of past realized...
