1. Are the statements on specific impacts of E-Commerce true? If yes, what are the prerequisites? If no, what are the reasons? - Yes the statements are true. These are the prerequisite of e-commerce: 1.) Ex-Ante Information, as Perceived by Buyers, while going through the ex-ante stage of a transaction customers are searching and interpreting information before arriving at a final purchase decision. Without the right amount and quality of information it is very unlikely that a customer will decide to complete a transaction. In other words, the availability of required information can be seen as a prerequisite for successful e- commerce. 2.) Institutions to Provide Assurance of Quality, before the advent of the Industrial Revolution, trade was conducted in a more and less direct fashion. You knew your tailors, your butcher-store, your sausage producers and barber. Their reliability and the quality of their goods and service were something you learned from direct experience and from your social circle. The Industrial Revolution changed all this. You bought cloth from a distant producer, etc. Brand as a kind of business practice evolved to fulfil this need of the enlarged market. As a kind of social institution, brand provides a statement of the quality of a product, incorporating attributes of reliability, craftsmanship in the process of production, etc. In other words, it can be perceived as a very compact statement of information about the product. Next to product quality a brand might also inform the customer about the quality and certainty of the transaction process. It might be an indication for the ex-ante and ex-post care that is taken over the customer. Therefore, a brand might even be capable to decrease customer's perceived risk about sensitive topics like security of payment, delivery and privacy. It is clear that this kind of brand inuence, refers to the brand of the selling company and not to the brand of the product itself. In some circumstances this might be the same but it is no matter of course. Lastly, Transport and Financial Infrastructure, and Technological Systems, once a customer decides to buy the product on offer on a Website, he has to pay the on-line shop. Here the payment system comes in handy. After the payment is made and a sale is clinched. the transport of the purchase would have to depend on an efficient and reliable infrastructure of transport logistics. And in the case of expensive goods, we may need to include the services of insurance companies. As to durable goods sold to distant customers, the customers must be able to obtain reliable and efficient repair and maintenance services
