Editing Examples

Here are two paragraphs, before and after copyediting. These are rather extreme examples; most text does not require this much editing.

One might attempt to fall back on “the law of comparative advantages” in explaining the Japanese rise in the auto industry. One alleged fact disturbs that theory since it has been suggested that Japanese auto plants in the United States are nearly as efficient as those in Japan. The strength of this book, a rigorous econometrics application of a general cost function yields results which when analyzed with the data trends of the 1980s are consistent with the management hypothesis—that differences in management techniques and the effectiveness of management explains relative performance between Japanese and North American auto producers.

Given this, one can consider public goods economies (in this case the sets of alternatives over which individual and social preferences are defined are identical) or/and private-goods economies (in the Arrow-Debreu framework, individual preferences are defined over a subset of the Euclidean space of, say, k dimensions if there are k goods, and the normative concept, Pareto-optimality, is defined over the n-fold cartesian product of the former space if there are n individuals—note that what seems interesting is to choose the “best” Walras allocations, i.e., the aggregation function must give rise to a set of best equilibrium allocations, then going further than the classical new welfare economics theorems: in this sense … allocations could be selected).
 
¶2 (after editing)
For public-goods economies, the sets of alternatives over which individual and social preferences are defined are identical. In the Arrow–Debreu framework, individual preferences in private-goods economies are defined over a subset of the Euclidean space of (say) k dimensions if there are k goods, whereas the normative concept of Pareto optimality is defined over the n-fold Cartesian product of Euclidean space if there are n individuals. (Note that we are interested in choosing the “best” Walras allocations; i.e., the aggregation function must give rise to a set of best equilibrium allocations and so goes beyond the theorems of classical welfare economics. In this sense, … allocations could be selected.)
