What is a sales ledger​

The sticky-price theory asserts that the output prices of some goods and services adjust slowly to changes in the price level. suppose firms announce the prices for their products in advance, based on an expected price level of 100 for the coming year. many of the firms sell their goods through catalogs and face high costs of reprinting if they change prices. the actual price level turns out to be 110. faced with high menu costs, the firms that rely on catalog sales choose not to adjust their prices. sales from catalogs will

The board of directors is the highest ranking body in a corporation, and the chairman of the board is the highest ranking individual. the ceo generally works under the board and its chairman, and the board generally has the authority to remove the ceo under certain conditions. the ceo, however, cannot remove the board, but he or she can endeavor to have the board voted out and a new board voted in should a conflict arise. it is possible for a person to simultaneously serve as ceo and chairman of the board, though many corporate control experts believe it is bad to vest both offices in the same person. true false

Reliability and validity reliability and validity are two important considerations that must be made with any type of data collection. reliability refers to the ability to consistently produce a given result. in the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. to illustrate this concept, consider a kitchen scale that would be used to measure the weight of cereal that you eat in the morning. if the scale is not properly calibrated, it may consistently under- or overestimate the amount of cereal that’s being measured. while the scale is highly reliable in producing consistent results (e. g., the same amount of cereal poured onto the scale produces the same reading each time), those results are incorrect. this is where validity comes into play. validity refers to the extent to which a given instrument or tool accurately measures what it’s supposed to measure. while any valid measure is by necessity reliable, the reverse is not necessarily true. researchers strive to use instruments that are both highly reliable and valid.
