| X-efficiency | The ability of a firm to get maximum output from its inputs. Failure to do so, called X-inefficiency or technical inefficiency, may be due to lack of incentives provided by competition. Improvement in X-efficiency is one hypothesized source of gain from trade. Term is due to Leibenstein (1966). |

By the numbers
Or you can do it by the numbers. Put &#xxx; in place of the character, where xxx is one of the numbers in the table below. In that case you'll get the symbol shown in the table.
Example: Write <font face="symbol">"</font>
Get "
(Without the font tag, xx; will just get you the ascii character. This useful for a few of them that cannot be gotten from the keyboard. See the second table below.)
