| A recently developed demand system, nicknamed AIDADS, offers a more general approach to capturing consumption preferences. AIDADS generalizes the LES by assuming marginal budget shares vary indirectly with expenditure. AIDADS is limited by the fact that the subsistence parameters are constant across expenditure. We modify AIDADS by replacing the constant subsistence parameters with a function which varies with utility, and hence expenditure. The modified AIDADS (MAIDADS) allows subsistence levels to vary with expenditure. This model is applied to the 1996 International Consumption Project data. As these data span a wide range of expenditure levels, MAIDADS offers a viable alternative when estimating "global demand systems." Results suggest... |

| To lower the incidence of human food-borne disease, experts and stakeholders have urged the development of a science- and risk-based management system in which food-borne hazards are analyzed and prioritized. A literature review shows that most approaches to risk prioritization developed to date are based on measures of health outcomes and do not systematically account for other factors that may be important to decision making. The Multi-Factorial Risk Prioritization Framework developed here considers four factors that may be important to risk managers: public health, consumer risk perceptions and acceptance, market-level impacts, and social sensitivity. The framework is based on the systematic organization and analysis of data on these multiple factors.... |

| 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... |

| 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.... |

| A newly developed demand system is used to estimate the response of food and food product demand to per capita expenditure changes. The resulting Engel elasticities are then used to project food and food product demand in 2020 assuming per capita expenditure and population changes. Results suggest that while food expenditure is projected to grow, it accounts for a smaller proportion of total expenditure. Further analysis indicates change in the composition of food demand away from a grain and towards livestock is projected to occur in lower income countries in 2020. |

| In light of the discovery of BSE infected cattle in Canada in 2003, a number of efforts have been undertaken to ensure the safety of beef produced in Canada. Recent discussion has focused on testing live cattle for the BSE prion. This paper investigates consumer acceptance and valuation of beef from live cattle that have been tested for BSE. Using data from an internet-‐based survey of English speaking Canada, single bound estimates of WTP are measured. Expected WTP is 43 per cent for the entire sample, but ranges from 52 per cent for respondents with a high purchase intention to 28 per cent for those with less than a high purchase intention. Nevertheless, the proportion of respondents who were predicted to purchase a tested beef product was small, and... |

| 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. |

| 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... |

| Despite record global economic growth in past decade malnutrition remains a serious problem in many parts of the world. According to the United Nations Food and Agriculture Organization (FAO), about 800 million people (17% of the worlds population) remain malnourished. For these households at a subsistence level of income, changes in commodity market conditions, as may arise from changes in global economic growth and/or trade policy can have serious consequences for nutritional intake. Even a small decline in diet quality can have substantial adverse impacts on health status. On the other hand, a modest income boost, or lower food prices, could have extremely positive impacts. Previously, the links between changes in the global economy and nutritional... |

| 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. |

| Until two years ago, most citizens of Canada, the United States and Mexico experienced terrorism as a distant reality viewed from the safety of their living rooms. Today, North Americans encounter constant reminders of the aggravation and economic costs imposed on them by the now real threat of terrorism. The United States, the most obvious target for new terrorist activity, has responded by tightening its border security with all countries including its NAFTA partners.(2) Canada and Mexico joined the NAFTA to obtain preferred and more secure access to the United States market. The increased threat of terrorist activity in North America raises three crucial questions for NAFTA members. First, how real is a bioterrorism threat? Second, how can the United... |
