GST/VAT should apply to groceries in Canada. Misconceptions have led many Canadians to oppose taxing groceries or special interest groups to complain about the inequities inherent in taxing some food products but excluding others. With a broader GST base, for example by including groceries, the...

The Florida orange juice industry has experienced great challenges-declining orange juice consumption and a domestic supply shortage that has led to increasing imports over the past decade. As growers look for a foothold, the question remains whether it is better to continue promoting orange...

Every organisation that produces product evaluates their performance at certain intervals to keep the pace with the market. Forecasts are evaluated to improve models to achieve better policy and planning outcomes. The purpose of this study is to observe whether the forecast errors are within the...

In the famous “orange juice puzzle,” a large amount of inexplicable price volatility arises in frozen concentrated orange juice (FCOJ) futures contracts. Temperature is considered the most important fundamental factor in this market, but its explanatory power is low and limited, so are those...

The aim of the paper is to emphasize the dependence between the return of the futures price of the frozen concentrated orange juice (FCOJ) and the variation of the temperature. Following Roll (1984) that proved that the market of frozen concentrated juice is influence by weather variable, we...

Cider production and consumption is growing rapidly within the USA; however, only estimates exist regarding the output from craft cider operations. Alongside the growth of the craft, beer market in the USA has been a resurgence of interest in craft cideries; according to the United States...

Discrete choice models of aggregate demand, such as the random coefficients logit, can handle large differentiated products categories parsimoniously while still providing flexible substitution patterns. However, the discrete choice assumption may not be appropriate for many categories in which...

We discuss inference for additive models with random scaling factors. The additive effects are of the form (1+g)f(z) where f is a nonlinear function of the continuous covariate z modeled by P(enalized)-splines and 1+g is a random scaling factor. Additionally, monotonicity constraints on the...

We combine two data sets to study price rigidity. The first consists of weekly time series of retail, wholesale, and spot prices for twelve products. These time series contain two exogenous cost shocks. We find that prices exhibit more rigidity in response to the second shock than the first. The...
