Constructing a theoretical framework and using a survey data of 294 customers from 25 supermarkets in Beijing, this paper studies the willingness to pay (WTP) for additive-free Mooncakes in Beijing and finds that age and income are important for WTP for “food safety” in China. Income is...

We consider Poisson’s equation for discrete-time single-birth processes, and we derive its solutions by solving a linear system of infinitely many equations. We apply the solution of Poisson’s equation to obtain the asymptotic variance. The results are further applied to birth–death...

Consumers are facing a trade-off between the benefits of an increase in the length of the shelf life of food, such as low food costs, and the potential health damages caused by food preservatives. However, few studies in the current literature place emphasis on food preservatives, neither from a...

Accurate estimation of the state of charge (SOC) of batteries is one of the key problems in a battery management system. This paper proposes an adaptive SOC estimation method based on unscented Kalman filter algorithms for lithium (Li)-ion batteries. First, an enhanced battery model is proposed...

The relationship between publically reported weekly grid premiums and discounts for specific carcass characteristics and the percentage of those characteristics reflected in total weekly slaughter volume (i.e., proportional slaughter volume) is investigated. Granger Causality and multi-lag VAR...

As the socialist system in China embraces the market economy, it has created many conflicts of interests and collusion between firms and different layers of governments. The central government in China sets regulations to ensure the quality of firms listed in the capital market, while local...

Mandatory livestock price reporting (MPR) was implemented in April 2001. Empirical evidence indicates a significant change in the weekly variability of publicly reported fed cattle grid premiums and discounts occurred after MPR implementation. We evaluated the effect of increased market...

There exists general agreement that the steam engine’s rise in importance occurred at the same time as large increases in firm size and growing urbanization, but no consensus concerning the degree to which the steam engine served as an exogenous force fueling urban growth. We reexamine the...
