Holt, Matthew T.. 
It is shown that the firstorder differential acreage allocation model developed by Bettendorf an Bloome and by Barten and Vanloot, and based on certainty equivalent profit maximization, may be extended to a levels version. The levels model, referred to as a linear approximate acreage allocation model, is potentially useful when panel or crosssectional data are employed. An empirical application with U.S. statelevel corn flex acreage data for the period 199195 indicates the feasibility of the approach. Estimated price and scale elasticities are generally larger than previous estimates, and are perhaps indicative of acreage response under the provisions of the 1996 Farm Act.

Holt, Matthew T.; Moschini, GianCarlo. 
The role of price risk in sow farrowings is investigated by using bivariate ARCHM and GARCHM models and a nonparametric kernel estimator. To account for the relevant time horizon of irreversible supply decisions, predictions for mean price and conditional price variance are iterated forward. The empirical results vary markedly in terms of their implications for risk response in hog supply decisions, with the ARCHM and GARCHM models suggesting a small and negative risk effect. Estimates of the marginal risk premium also indicate moderate and variable departures from marginal cost pricing in sow farrowing supply decisions.

Haigh, Michael S.; Holt, Matthew T.. 
This paper presents an effective way of combining two popular, yet distinct approaches used in the hedging literature dynamic programming (DP) and timeseries (GARCH) econometrics. Theoretically consistent yet realistic and tractable models are developed for traders interested in hedging a portfolio. Results from a bootstrapping experiment used to construct confidence bands around the competing portfolios suggest that while DPGARCH outperforms the GARCH approach they are statistically equivalent to the OLS approach when the markets are stable. Significant gains may be achieved by a trader, however, by adopting the DPGARCH model over the OLS approach when markets exhibit excessive volatility.

He, Dequan; Holt, Matthew T.. 
Market efficiency and unbiasedness tests are performed for the first time for three forest commodity futures markets: softwood lumber, oriented strand board (OSB), and northern bleached softwood kraft pulp (NBSK). The Johansen cointegration procedure is applied to test longterm market efficiency, while the standard error correction models (ECM) and ECM with GQARCHinmean process are also used to examine shortterm market efficiency and unbiasedness. Results show that these markets are inefficient and biased in both the longterm and shortterm. Results also indicate that no shortterm timevarying risk premiums are found in these commodity futures markets.

Hilmer, Christiana E.; Holt, Matthew T.. 
Whereas consumer theory employs several different empirical specifications for estimating indirect utility functions, producer theory has relied on the Translog specification to estimate the indirect production function. In this paper, we apply Lewbel’s more general functional specification and investigate its implications for the estimation of indirect production functions in productivity analysis. An attractive feature of the Lewbel model is that it nests both the Translog and the almost ideal supply system, offering a method to assess the empirical validity of all three specifications. Aggregate U.S. production data are used to examine the performance of the three models in an empirical application.

Bishop, Richard C.; Holt, Matthew T.. 
A variety of regulations may affect commercial fish catches. We take here as a case in point steps to reduce losses of aquatic organisms due to impingement and entrainment (I&E) at power plants. Methods to evaluate the benefits of such measures are needed for benefitcost analysis. We use a new approach to estimating ex vessel demand by Holt and Bishop (2002) to address the portion of the benefits that occur postharvest, that is, down the marketing chain after fishermen sell their catches. The model deals with the dockside prices and quantities for six major commercial species harvested from the U.S. Great Lakes. We use the model to explore the potential magnitude of postharvest benefits for Great Lakes fisheries. We then turn to a possible approach...

Aradhyula, Satheesh V.; Holt, Matthew T.. 
This article applies recent developments in timeseries modeling to analyze the retail prices of beef, pork, and chicken. Specifically, generalized autoregressive conditional heteroscedasticity (GARCH) models were fitted to these data to determine if, unlike more traditional timeseries models, the conditional variances of the underlying stochastic processes are nonconstant. The estimation results indicate that the constant conditional variances assumption can be rejected. Furthermore, ex post forecast intervals generated from the GARCH processes indicate that the forecasting accuracy of the estimated models has varied widely over time with substantial volatility occurring during the 1970s and early 1980s.

Haigh, Michael S.; Holt, Matthew T.. 
Foreign exchange hedging ratios are simultaneously estimated alongside freight and commodity ratios in a timevarying portfolio framework. Foreign exchange futures are found to be by far the most important derivative instrument to be employed in order to reduce uncertainty for traders. Our results lend support to the decision by LIFFE to cease trading the BIFFEX freight futures contract because of its low levels of trading activity, which likely resulted from its apparent unattractiveness as a hedging instrument.
