Measuring market power in the Greek food and beverages manufacturing industry AgEcon
Rezitis, Anthony N.; Kalantzi, Maria A..
This paper measures the degree of market power of the Greek food and beverages manufacturing industry over the period 1983–2007 at the three-digit SIC level. The present study also estimates the “deadweight” loss and the reduction of consumers’ income due to the possible existence of market power in the Greek food and beverages manufacturing industry. Based on Bresnahan’s (1989) conjectural variation model, three different approaches are used to investigate competitive conditions of the Greek food and beverages manufacturing industry. The first approach assesses the extent of market power of the whole industry over the period 1983–2007; the second approach tests the degree of market power in each one of the nine sectors of the industry over the whole...

Greek Beef Supply Response and Price Volatility under CAP Reforms AgEcon
Rezitis, Anthony N.; Stavropoulos, Konstantinos S..
This study examines the supply response of the Greek beef market and the possible effect of the European Union’s Common Agricultural Policy (CAP) on the Greek beef sector during the period 1993-2005. A GARCH process is used to estimate expected price and price volatility while several different symmetric, asymmetric and nonlinear GARCH models are estimated. The empirical results show that price volatility and feed price are important risk factors of the supply repose function, while the negative asymmetric price volatility which was detected implies that producers have a weak market position. Furthermore, the empirical findings confirm that the annual premium paid by EU to beef producers had a positive impact on the production level and that the change of...

Volatility Spillover Effects in Greek Consumer Meat Prices AgEcon
Rezitis, Anthony N..
This paper investigates volatility spillover effects, i.e. 'meteor showers' and 'heat waves', across consumer meat prices for lamb, beef, pork, and poultry. The empirical analysis used the methodology of the Generalized Autoregressive Conditional Heteroskedastic (GARCH) approach. The empirical results support the presence of significant 'meteor shower' and 'heat wave' effects across the four meat categories under consideration.

Food Price Volatility and Macroeconomic Factors: Evidence from GARCH and GARCH-X Estimates AgEcon
Apergis, Nicholas; Rezitis, Anthony N..
This article examines food price volatility in Greece and how it is affected by short-run deviations between food prices and macroeconomic factors. The methodology follows the GARCH and GARCH-X models. The results show that there exists a positive effect between the deviations and food price volatility. The results are highly important for producers and consumers because higher volatility augments the uncertainty in the food markets. Once the participants receive a signal that the food market is volatile, this might lead them to ask for increased government intervention in the allocation of investment resources and this could reduce overall welfare.

The Effect of Technological Change on Demand and Supply of Hired Farm Workers in the United States AgEcon
Mishra, Ashok K.; Rezitis, Anthony N..
This paper investigates the effect of technological change on the demand for, and supply of, hired farm workers in the United States for the period 1950 to 1992. Particular attention is given to the proxy for technological change. We have used total expenditures, both by public and private sectors, for research and development in the field of agriculture. We find that technology has a negative impact on the hired labor demand after the second and third year of initial investment. Our results show that technology is labor saving. The demand and supply elasticities were found to differ from other studies. We also derive elasticities of adjustment and draw some policy conclusions. The paper also presents a dynamic-in-period simulation of the estimated model.

Demand for Fall Annual and Perennial Plants: Pansies and Mums in Independent Garden AgEcon
Wohlgenant, Michael K.; Rezitis, Anthony N.; Safley, Charles D..
Analysis of demand for pansies and mums sold in independent garden centers indicates that price and age are important factors influencing demand. In the fall of 1996, data were collected from a survey of independent garden centers in North Carolina. Statistical analysis was conducted by estimating the relationship between consumer expenditure shares of pansies and mums and prices paid per plants, household income, and various demographic and product characteristic variables. The models were estimated by the least-squares method with correction for selectivity bias, resulting from zero purchases. Own-price elasticities of demand for pansies and mums of –0.80 and –0.76, respectively, were estimated. The results also indicate that older customers who live...

Investigation of Factors Influencing the Technical Efficiency of Agricultural Producers Participating in Farm Credit Programs: The Case of Greece AgEcon
Rezitis, Anthony N.; Tsiboukas, Kostas; Tsoukalas, Stauros.
This study investigates a number of factors influencing technical efficiency of Greek farms participating in the 1994 European Union (EU) farm credit program. Technical efficiency measures are obtained within the framework of a parametric stochastic frontier. Factors showing a positive effect on technical efficiency are value of liabilities, number of hours of mechanical operation, large land size, and rental land, whereas those showing a negative effect are value of EU product subsidies, value of off-farm family income, and hired labor. The value of investments incurred by farms because of their participation in the 1994 farm credit program does not show any significant effect on technical efficiency. The predicted levels of technical efficiency...

Greek meat supply response and price volatility in a rational expectations framework: A multivariate GARCH approach AgEcon
Rezitis, Anthony N.; Stavropoulos, Konstantinos S..
This paper examines supply response models in a rational expectations framework for each one of the four major Greek meat markets, i.e. beef, broiler, lamb and pork. A multivariate GARCH model with Cholesky decomposition is used to incorporate price volatility into the rational expectations supply response model for each meat category and as a result the conditional covariance matrix remains positive definite without imposing any restrictions on the parameters. The empirical results confirm the existence of rational behaviour by meat producers in the four examined markets and indicate that price volatility is a major risk factor in Greek meat production while feed prices and veterinarian medicine prices are both important cost factors. Furthermore, the...

Modeling Pork Supply Response and Price Volatility: The Case of Greece AgEcon
Rezitis, Anthony N.; Stavropoulos, Konstantinos S..
This paper examines the supply response of the Greek pork market. A GARCH process is used to estimate expected price and price volatility, while price and supply equations are estimated jointly. In addition to the standard GARCH model, several different symmetric, asymmetric, and nonlinear GARCH models are estimated. The empirical results indicate that among the estimated GARCH models, the quadratic NAGARCH model seems to better describe producers’ price volatility, which was found to be an important risk factor of the supply response function of the Greek pork market. Furthermore, the empirical findings show that feed price is an important cost factor of the supply response function and that high uncertainty restricts the expansion of the Greek pork...
