Motor vehicle stocks, scrappage, and sales

Article Abstract:

A framework for predicting the aggregate sales of new motor vehicles in the US is presented. The framework, which also include separate models for forecasting the change in vehicle stock and the rate of vehicle scrappage, is shown to be useful as a macroeconomic forecasting tool. The technique requires a minimum set of assumptions that include the prevailing demographic trends, the state of the economy, the preference of the consumers, the prices of new vehicles, repair costs and vehicle retirements.

Household gasoline demand in the United States

Article Abstract:

Gasoline demand in the US is strongly affected by household structure. An analysis of household-level data shows that gasoline consumption declines substantially with age. Specifically, the effect of age on the consumption of gasoline becomes evident only for households with head aged 50 years and above. Household size also affects gasoline demand with an elasticity of only about 0.1. No correlation exists between the decline in income elasticity of demand and high earnings.

World carbon dioxide emissions: 1950-2050

Article Abstract:

Reduced-form econometric model was utilized to evaluate predictions of carbon dioxide emissions made by the Intergovernmental Panel on Climate Change (IPCC). The model revealed that IPCC's predictions markedly differs from those based on recent historical record. An inverse U shaped relationship was established between carbon dioxide emissions per capita and per-capita income.
