We describe various computing techniques for tackling chessboard domination problems and apply these to the determination of domination and irredundance numbers for queens’ and kings’ graphs. In particular we show that γ(Q15) = γ(Q16) = 9, confirm that γ(Q17) = γ(Q18) = 9, show that γ(Q19) = 10, show that i(Q18) = 10, improve the bound for i(Q19) to 10 ≤ i(Q19) ≤ 11, show that ir(Qn) = γ(Qn) fo...

An identity links the rate of economic growth, the speed of poverty reduction and changes in the distribution of income during some time period in a given country. A few authors used that identity to understand the causes for observed changes in poverty and to identify the exact role of economic growth in poverty reduction. Yet, many empirical cross-country studies of the relationship between g...

Mongolian people often consume meat more than vegetable in diet due to traditional nomadic culture. Nowadays, the people’s has been changing who vegetables with associated urbanization (half of population live urban areas, mostly capital city). Even though consumption increased recently, market is still a high reliance on imports and threatening national food security. Since 2016, government es...

The member countries of the World Health Organization (WHO) have recently endorsed its Global Strategy on Diet, Physical Activity and Health in an effort to combat the growing burden of noncommunicable diseases. We assess the potential consumption impacts of these norms in the United States using a mathematical programming approach. We find that adherence to the WHO norms would involve signific...

For decades, earnings from farming in many developing countries have been depressed by a pro-urban bias in own-country policies, as well as by governments of richer countries favoring their farmers with import barriers and subsidies. Both sets of policies reduce national and global economic welfare and inhibit agricultural trade and economic growth. They almost certainly add to inequality and p...

Despite the resurgence of parastatal marketing boards and strategic grain reserves over the last decade in eastern and southern Africa, there is little empirical evidence about how their activities affect smallholder input use and cropping decisions. This paper uses panel survey data from 1997-2007 on Kenyan smallholders to investigate the effect of Kenya’s National Cereal Produce Board activit...

This study investigates how consumers value carbon dioxide (CO2) emissions of food by conducting a choice experiment before an ecolabel is attached on some foods in Japan. Participants are asked to buy some Satsuma mandarin oranges based on price and CO2 emissions and take them home. The following results are obtained: (i) the willingness-to-pay (WTP) estimate for the reduction of 1 g CO2 emiss...

To assess the impact of taxation on the consumption of sugar-sweetened beverages (SSB), most studies consider the average consumer. Individual consumption is, however, very heterogeneous. In this paper, we propose a three-step methodology to assess the impact of SSB taxation on individual consumption. First, we use a disaggregation method to recover individual consumption from observed househol...
