The Gravity Model and the Problem of Zero`s in Agrifood Trade AgEcon
Haq, Zahoor Ul; Meilke, Karl D.; Cranfield, John A.L..
and this is a problem when estimating log-linear gravity equations. This has caused many researchers to either ignore the zero trade flows or to replace the zero with a small positive number. Both of these actions bias the resulting parameter estimates of the gravity equation. In this study we correct for this misspecification by using the Heckman selection model to estimate bilateral trade flows for 46 agrifood products, for the period 1990 to 2000, for 52 countries. In our sample, selection bias rarely affects the signs of variables but often has a substantial effect on the magnitude, statistical significance and economic interpretation of the marginal effects. Hence, treating zero trade flows properly is important from both a statistical and an...

Options for Supply Management in Canada with Trade Liberalization AgEcon
Barichello, Richard R.; Cranfield, John A.L.; Meilke, Karl D..
Following the Uruguay Round of trade negotiations Canada replaced its import quotas on sensitive products with tariff rate quotas. The over-quota tariffs on those products operating under domestic supply management schemes (dairy and poultry products) ranged from a low of 155 percent on turkey to a high of 299 percent on butter. These tariffs have effectively blocked over quota imports and are likely to continue to prevent imports, under most market conditions, given the likely range of tariff cuts proposed for sensitive products following a successful completion of the Doha Round. However, it’s argued that tariff cuts in the post-Doha Round will severely limit Canada’s ability to restrict imports and it is important to use the next 15 years to better...

OPTIMAL ADVERTISING WITH TRADED RAW AND FINAL GOODS: THE CASE OF VARIABLE PROPORTIONS TECHNOLOGY AgEcon
Cranfield, John A.L..
An optimal advertising investment rule is derived for a vertically related, competitive market with traded final and raw goods and processing sector characterized by variable proportions technology and nonconstant returns to scale. An equilibrium displacement framework incorporating conditional factor demands is used to account for the elasticity of substitution between agricultural and nonagricultural inputs to the marketing channel. Simulation for the Canadian beef industry in the post-WTO environment demonstrates how optimal advertising intensity ranges between 0.05% and 0.22% of farm-level market revenue.

The Canadian Bioproducts Industry Analysis of the Bioproduct Development Survey - 2004 AgEcon
Sparling, David; Cranfield, John A.L.; Henson, Spencer J.; Laughland, Pamela.
Bioproducts are often presented as one of the potential saviours of Canadian agriculture, offering non-food applications for agricultural products. However, relatively little is known about the sector or the characteristics of the firms. This paper presents an analysis of the Canadian bioproducts sector based on the first survey of bioproduct firms in Canada. The survey was performed by Statistics Canada in 2004 using 2003 firm results. The paper analyzes the responses to the bioproducts survey on two important dimensions, by region and firm size. The results indicate that for most of Canada's 232 bioproducts firms, bioproducts are just one part of the business activities, accounting for less than one third of employees and slightly more than one quarter...

OPTIMAL COLLECTIVE INVESTMENT IN GENERIC ADVERTISING, EXPORT MARKET PROMOTION AND COST-OF-PRODUCTION REDUCING RESEARCH AgEcon
Cranfield, John A.L..
Optimal investment rules are developed for a producer agency investing in domestic market generic advertising, export market promotion, and cost of production reducing research. Analytical results show fundamental difference in optimal investment rules when the producer group is assumed to maximise either producers' surplus or social surplus. Incorporating a constraint limiting total expenditure on the three activities substantially alters the structure of the optimal investment rules. Results highlight the importance of accounting for the financing mechanism when modelling optimal producer investment. Simulation of the optimal intensities suggests the proposed budget of the Canadian Beef Cattle Research Market Development and Promotion Agency...

Canadian Consumer's Willingness-To-Pay For Pesticide Free Food Products: An Ordered Probit Analysis AgEcon
Cranfield, John A.L.; Magnusson, Erik.
A new crop production system has emerged in western Canada. Pesticide Free ProductionTM (PFPTM) emphasizes reduced pesticide use in conjunction with increased reliance on producer knowledge of agronomic practices that mitigate weed, insect and disease pressure. A contingent valuation survey was undertaken to determine if Canadian consumers would pay a premium for PFPTM food products. Over 65 percent of respondents would be willing to pay a one to ten percent premium relative to a conventional food product. Five percent of respondents would be willing to pay more than a 20 percent premium. Health and environmental concerns, willingness to switch grocery stores and youth are important characteristics of consumers who would be willing to pay higher premiums....

IMPLICIT ADDITIVE PREFERENCES: A FURTHER GENERALIZATION OF THE CES AgEcon
Preckel, Paul V.; Cranfield, John A.L.; Hertel, Thomas W..
The CES is generalized by extension of the work of Hanoch (1975) resulting in implicit, direct and indirect relationships between utility and consumption. Expressions for substitution and income elasticities are developed and observed to be variable, rather than constant as in the CES case.

Factors Influencing the Body Mass Index of Adults in Canada AgEcon
Cranfield, John A.L..
This paper explores socio-demographic, economic and behaviour factors influencing body mass index (BMI) amongst 20 to 64 year old adults in Canada. BMI scores in Canada have increased, with gains stemming from disproportionate increases in female BMI. Econometric results indicate higher BMI scores for males, those born in Canada, those in food insecure homes and whites. Age-gender interactions suggest different patterns of BMI adjustment over the life of males and females; a pronounced inverse quadratic relationship between with age and male BMI is noted, while female BMI increases with age. Education, used as a gauge of inequality, is inversely related to BMI, while income has a muted effect. BMI is inversely related to level of physical activity, an...

An Analysis of Financing Innovation and Commercialization in Canada's Functional Food and Nutraceutical Sector AgEcon
Cranfield, John A.L.; Herath, Deepananda P.B.; Henson, Spencer J.; Sparling, David.
Growing consumer interest in functional foods and nutraceuticals has been seen as a significant business opportunity for the agri-food sector. Many of the new firms in this sector are small and medium sized enterprises (SMEs). These SMEs often face difficulties in obtaining financing for their functional food and nutraceutical innovation activities. We develop and implement two models to show what factors affect a firm's decision to seek external financing and the level of financing obtained. Firm size, being privately held and engaging in contractual arrangements, have negative impacts on the likelihood of a firm seeking external funding, while firms which are intensively involved in the functional food and nutraceutical sector, with greater prospects...

POVERTY IMPACTS OF MULTILATERAL TRADE LIBERALIZATION AgEcon
Hertel, Thomas W.; Preckel, Paul V.; Cranfield, John A.L.; Ivanic, Maros.
Poverty reduction is an increasingly important consideration in the deliberations over multilateral trade liberalization. However, the analytical procedures used to assess the impacts of multilateral trade liberalization on poverty are rudimentary, at best. Most poverty studies have focused on a single country using detailed household survey data. When it comes to multi-country, global trade liberalization analyses, researchers are forced to resort to a discussion of average, or per capita effects, suggesting that if per capita real income rises, then poverty will fall. As we show in this paper, such an inference can be misleading. Our paper combines results from a newly available international, cross-section consumption analysis for 1996, with earnings...

TRADE LIBERALIZATION AND THE STRUCTURE OF POVERTY IN DEVELOPING COUNTRIES AgEcon
Hertel, Thomas W.; Ivanic, Maros; Preckel, Paul V.; Cranfield, John A.L..
“"Globalization increases poverty"” is a common assertion made by critics of globalization. The proliferation of low-wage jobs and higher food prices are some of the arguments brought forward in support of this argument. One of the hallmarks of globalization is the systematic dismantling of barriers to trade. Advocates of trade liberalization – particularly industrialized country agriculture reform – argue that the ensuing rise in world prices for agriculture products will boost rural incomes, thereby reducing poverty in the poorest countries, where the bulk of world poverty resides. Who is right? The goal of this paper is take a systematic look at the structure of poverty across a range of developing countries in Africa, Asia and Latin America, and...

Demands for Food Products Across the Development Spectrum: Application of a Rank Four Demand System AgEcon
Cranfield, John A.L..
A rational rank four AIDS model (RAIDS) is used to estimate consumer demands for final goods and services in countries spanning the development spectrum. RAIDS is used as it provides more general price and expenditure responses. It also nests the Quadratic and non-liner AIDS models. RAIDS is estimated using the entire sample and sub-samples based on the country's level of per capita expenditure. Results indicate selection of nested functional form differs by sub-sample. AIDS is selected for the low per capita expenditure countries, sample is considered. Differences in parameter estimates manifest themselves in price and Engel elasticities. Such differences warrant caution when using global demand systems to undertake policy analysis.

What impact has food price inflation had on consumer welfare: a global analysis AgEcon
Cranfield, John A.L.; Haq, Zahoor Ul.
The impact of rising global food prices on consumer welfare is investigated. A quadratic AIDS model is estimated using data spanning countries at various levels of economic development. Statistical comparison suggests the QUAIDS model is preferred over the non-linear AIDS model. Estimated parameters are used to calibrate a QUAIDS indirect utility function and base utility for welfare analysis. Compensated variation associated with recently observed food price inflation for different foods in different income cohorts of countries is calculated. Per capita compensated variation increases with per capita expenditure. However, per capita compensated variation expressed as a percent of per capita expenditure falls as one moves from less developed to more...

MISASSESSED RISK IN CONSUMER VALUATION OF FOOD SAFETY: AN EXPERIMENTAL APPROACH AgEcon
Brown, Jennifer; Cranfield, John A.L.; Henson, Spencer J..
This study estimates Canadian consumers' willingness to pay for food safety improvements and identifies systematic misassessments of food-borne risks. Non-hypothetical experimental auctions were used to elicit consumer valuations of food safety improvement. Consistent with behavioural research, results suggest that subjects generally overestimate the likelihood of becoming ill due to food-borne disease relative to scientifically-estimated odds. Subjects were willing to pay a positive amount to reduce food-safety risk. Risk reductions' valuations increased with higher initial risk, supporting arguments of diminishing marginal value for risk reductions.

PERSISTENCE OF PRICE-COST MARGINS IN THE U.S. FOOD AND TOBACCO MANUFACTURING INDUSTRIES: A DYNAMIC SINGLE INDEX MODEL APPROACH AgEcon
Cranfield, John A.L..
Persistence of price-cost margins in the U.S. food and tobacco manufacturing industries is measured while accounting for price-cost margin risk. Direct measurement of persistence and of long- and short-run price-cost margin risk is accomplished by incorporating a partial-adjustment framework into the Single Index Model. Results indicate persistence of price-cost margins. Short-run margin risk is accounted for primarily by diversifiable risk. Long-run margin risk, which depends on systematic risk alone, is generally lower than the short-run measure. Factors influencing persistence and the systematic relationship between industry margins and a market index are explored.

Factors Affecting Biotechnology Innovation in Canada: Analysis of the 2001 Biotechnology Use and Development Survey AgEcon
van Moorsel, Daryl; Cranfield, John A.L.; Sparling, David.
Advancement in biotechnology requires continued innovative activity by firms. To grow, biotechnology firms must understand the factors affecting their innovative activity. Such understanding also informs policy makers, and supports the development of policies promoting one's biotechnology sector. This study explores factors which determine innovative activity within the Canadian biotechnology industry. Innovative activity is measured as the natural log of the number of products/processes a firm has at different stages of the innovation spectrum. A model is developed to regress this measure on several determinants of innovation. Significant drivers of innovation include: collaborative arrangements, transfer of intellectual property, firm size and age,...
