Levels, Differences And Ecms – Principles For Improved Econometric Forecasting, P. Geoffrey Allen, Robert Fildes Jan 2004

Levels, Differences And Ecms – Principles For Improved Econometric Forecasting, P. Geoffrey Allen, Robert Fildes

PERI Working Papers

An avalanche of articles has described the testing of a time series for the presence of unit roots. However, economic model builders have disagreed on the value of testing and how best to operationalise the tests. Sometimes the characterization of the series is an end in itself. More often, unit root testing is a preliminary step, followed by cointegration testing, intended to guide final model specification. A third possibility is to specify a general vector autoregression model, then work to a more specific model by sequential testing and the imposition of parameter restrictions to obtain the simplest data-congruent model ‘fit …


Direct And Market Effects Of Enforcing Emissions Trading Programs: An Experimental Analysis, James J. Murphy, John K. Stranlund Jan 2004

Direct And Market Effects Of Enforcing Emissions Trading Programs: An Experimental Analysis, James J. Murphy, John K. Stranlund

PERI Working Papers

Since firms in an emissions trading program are linked together through a permit market, so too are their compliance choices. Thus, enforcement strategies for trading programs must account for not only the direct effects of enforcement on compliance and emissions decisions, but also the indirect effects that occur because changes in enforcement can induce changes in permit prices. This paper uses laboratory experiments to test for these direct and indirect market effects. Consistent with theoretical predictions, we find a direct effect of enforcement on individual violations, as well as a countervailing market effect through the permit price. Thus, the productivity …


An Economic Valuation Of Recreational Shellfishing On Cape Cod, David T. Damery, P. Geoffrey Allen Jan 2004

An Economic Valuation Of Recreational Shellfishing On Cape Cod, David T. Damery, P. Geoffrey Allen

PERI Working Papers

Estimated total value for recreational shellfishing on Cape Cod was $7.4 million in 2002, based on results of a survey of 233 shellfish permit holders, a figure that has roughly kept pace with inflation based on a similar study conducted in 1975. The total value is made up of two components, the actual permit fees collected ($387,000) and an estimate of consumer surplus, which was based on willingness to accept compensation to give up a fishing permit and hence is unbounded by the survey respondents’ income. An estimate based on willingness-to-pay (WTP) gave a total value estimate of $1.0 million …


Pricing-To-Market: Price Discrimination Or Product Differentiation?, Nathalie Lavoie, Qihong Liu Jan 2004

Pricing-To-Market: Price Discrimination Or Product Differentiation?, Nathalie Lavoie, Qihong Liu

PERI Working Papers

We employ a vertical differentiation model to examine the potential bias in pricing-tomarket (PTM) results when using unit values aggregating differentiated products. Our results show that: i) false evidence of PTM (“pseudo PTM”) is always found when using unit values, whether the law of one price holds or not; and ii) the extent to which results are biased due to pseudo PTM increases with the level of product differentiation. Correspondingly, our simulation results suggest that: i) it is possible to get a statistically significant estimate of the exchange rate coefficient, even when there is no real PTM; ii) the probability …


Hypothetical Bias In Dichotomous Choice Contingent Valuation Studies, Michael Ash, James J. Murphy, Thomas H. Stevens Jan 2004

Hypothetical Bias In Dichotomous Choice Contingent Valuation Studies, Michael Ash, James J. Murphy, Thomas H. Stevens

PERI Working Papers

This paper uses a meta-analysis to explore the relationship between hypothetical bias and the price respondents are asked to pay. For public goods, the results clearly indicate a difference in the price elasticity between hypothetical and actual payment conditions. Since the bias increases for larger dollar amounts, any simple guidelines, such as NOAA’s “divide by two” rule of thumb, could be misleading. Future attempts to calibrate contingent valuation responses should reflect this price sensitivity.


The Economics Of Implementing Traceability In Beef Supply Chains: Trends In Major Producing And Trading Countries, Diogo M. Souza-Monteiro, Julie A. Caswell Jan 2004

The Economics Of Implementing Traceability In Beef Supply Chains: Trends In Major Producing And Trading Countries, Diogo M. Souza-Monteiro, Julie A. Caswell

PERI Working Papers

Countries have implemented traceability systems, especially after discovery of BSE in cattle, in order to quickly identify hazard sources. We compare the economic impacts of mandatory and voluntary systems in the EU, Japan, Australia, Brazil, Argentina, Canada, and the United States in terms of the systems’ breadth, depth, and precision.


Food Safety Innovation In The United States Evidence From The Meat Industry, Elise Golan, Tanya Roberts, Elisabete Salay, Julie Caswell, Michael Ollinger, Danna Moore Jan 2004

Food Safety Innovation In The United States Evidence From The Meat Industry, Elise Golan, Tanya Roberts, Elisabete Salay, Julie Caswell, Michael Ollinger, Danna Moore

Julie Caswell

Recent industry innovations improving the safety of the Nation’s meat supply range from new pathogen tests, high-tech equipment, and supply chain management systems, to new surveillance networks. Despite these and other improvements, the market incentives that motivate private firms to invest in innovation seem to be fairly weak. Results from an ERS survey of U.S. meat and poultry slaughter and processing plants and two case studies of innovation in the U.S. beef industry reveal that the industry has developed a number of mechanisms to overcome that weakness and to stimulate investment in food safety innovation. Industry experience suggests that government …


Enforcing Transferable Permit Systems In The Presence Of Transaction Costs, Carlos A. Chavez, John K. Stranlund Jan 2004

Enforcing Transferable Permit Systems In The Presence Of Transaction Costs, Carlos A. Chavez, John K. Stranlund

PERI Working Papers

In this paper we examine the impacts of transaction costs on enforcing a transferable emissions permit system. We derive an enforcement strategy with a self-reporting requirement that achieves complete compliance in a cost-effective manner. In the absence of transaction costs targeted enforcement—the practice of monitoring some firms more closely than others—is neither necessary nor desirable. In the presence of constant marginal transaction costs, buyers of permits should be monitored more closely than sellers, but within groups of buyers and sellers monitoring should be uniform. When marginal transaction costs are not constant, effective monitoring will depend on whether a firm is …


Attitudes Towards Alternative Management Policies For Public Recreation Lands, Mihail Samnaliev, Thomas Stevens, Thomas More Jan 2004

Attitudes Towards Alternative Management Policies For Public Recreation Lands, Mihail Samnaliev, Thomas Stevens, Thomas More

PERI Working Papers

Public recreation land management agencies have been searching for ways to increase revenue. User fees as implemented by the Fee Demonstration Program have received the most attention. Corporate sponsorships and private donations have also been implemented and other options, such as partial privatization, closure of some areas, and different forms of public-private partnerships have been debated. The present paper reports results from a 2002 mail survey of randomly selected Idaho and New Hampshire households, designed to elicit public attitudes about a wide variety of management policies for public (federal/state) recreation lands. The most socially acceptable forms for raising revenue were …
