A disadvantage of the result-based approaches to performance measurement is that individuals may focus only on aspects of their performance that are measured, neglecting those that are not.

…… The alternative is a pick-and-mix social landscape. At the moment ethnic minorities are moving in different directions at different rates, with personal and social engagement across ethnic boundaries increasing all the time. One crude indicator is the level of mixed race marriage: one in five Bangladeshi and Pakistani men born in Britain now has a white wife, and one in five babies born in Britain has one Afro-Caribbean and one white parent. This implies a Britain in which people will construct multiple identities defined by all sorts of factors: class, ethnicity, gender, religion, profession, culture and economic position. It won't be clear-cut. Not all ethnic minorities, or members of an ethnic minority, will be moving in the same direction or identifying the same issues at the heart of their identities. It's about deciding who you are, but also about how other people define you. That's what will be at the heart of the next 50 years: enduring communities linked by blood through time versus flexible, constantly shifting identities. Identity won't be about where you have come from; it will be a set of values you can take anywhere that is compatible with full participation in whichever society you live in.

When our population is so small that all our labor can be engaged in the group represented by A, productivity of labor (and therefore wages) will be at their maximum. When our population increases so that some of the labor will have to be set to work in group B, the wages of all labor must decline to the level of the productivity in that group. But no employer, without government aid, will yet be able to afford to hire labor to exploit the opportunities represented by C and D, unless there is a further increase in population. But suppose that the political party in power holds the belief that we should produce every thing that we consume, that the opportunities represented by C and D should be exploited. The commodities that the industries composing C and D will produce have been hitherto obtained from abroad in exchange for commodities produced by A and B. The government now renders this difficulty by placing high duties upon the former class of commodities. This meads that workers in A and B must pay higher prices for what they buy, but do not receive higher prices for what they sell. After the duty has gone into effect and the prices of commodities that can be produced by C and D have risen sufficiently, enterprisers will be able to hire labor at the wages prevailing in A and B, and establish industries in C and D. So far as the remaining laborers in A and B buy the products of C and D, the difference between the price which they pay for those products and the price that they would pay if they were permitted to import those products duty-free is a tax paid not to the government, but to the producers in C and D, to enable the latter to remain in business. It is an uncompensated deduction from the natural earnings of the laborers in A and B. Nor are the workers in C and D paid as much, estimated in purchasing power, as they would have received if they had been allowed to remain in A and B under the earlier conditions. When C and D are established, workers in these industries______. A．receive higher wages than do the workers in A and B B．receive lower wages than do the workers in A and B C．are not affected so adversely by the levying of duties as are workers in A and B D．receive wages equal to those workers in A and B
