Modelling Intercontinental Tourism Consumption in South Africa: A Systems‐of‐Equations Approach

This paper investigates the pattern of inbound tourists' consumption in South Africa, examining four main intercontinental markets and five different tourism goods. The empirical investigation develops an almost ideal demand system (AIDS) model and it extends recent research by allowing tourists to base their spending decision on the real effective price differences between South Africa and their home country. The results show that tourist spending in South Africa is a luxury good, and tourists react normally to a change in the relative price of goods. The cross‐price elasticities suggest that the preferences of different markets influence their view of substitutability and complementary effects between various products in South Africa.

姥姥的西瓜酱

孔子说食不厌精,还说不得其酱不食,看来圣人的嘴头也够挑,不同的食物要搭配不同的酱才下箸。其实在古代酱与菜肴的结伴出席是周礼的一部分,规矩极多,官宴或祭祀的场合都是先上酱,继而搭配进食的菜肴,如此一道一道间杂呈上,赴宴的贵族通过看酱预知下道菜的名目,方使得不会失礼。到后来以至今日,礼崩乐坏的年代,自然是不讲究这些了,不过各乡制酱的风俗却源远流长下来。东北大酱,老北京甜面酱,郫县豆瓣酱,福建沙茶酱,苏州虾子酱,广东梅子酱,菌菇酱,牛肉酱,豉酱,阿香婆辣酱,西洋番茄酱......数起来恐怕是很难一气讲完的,我乡有一种西瓜酱,不知是否独美,至少我不曾在别处见过。
