## 经济代写|产业经济学代写Industrial Economics代考|Exit rates by size rank of producer

Table $5.3$ gives information on the relative size of exiting firms. The table is in the form of a matrix in which the columns correspond to the number of producers at the start of the exit year and the rows correspond to the size rank of the firm (based on capacity at the start of the year). Within each column, exit rates have been normalized to sum to unity.

Table $5.3$ shows that small firms had disproportionately high exit rates. Within each column of the table, the majority of exits lie below the mean rank. This propensity of smaller firms to exit is highly significant statistically. ${ }^{12}$ Results are similar if marginal producers are excluded from the analysis, ${ }^{13}$ or if firms are ranked on the basis of capacity in the peak year rather than the exit year. ${ }^{14}$

Thus the data sample offers no support for the G\&N (1985) model, which predicts that the largest producers will be first to exit. Indeed, of the firms with largest capacity for each product in the peak year, only three of the 30 exited, as compared with 38 per cent of firms in the sample as a whole.

## 经济代写|产业经济学代写Industrial Economics代考|Total divestment

The preceding analysis shows that small firms were more likely to exit, whereas large firms were more likely to cut capacity incrementally. Which group, on balance, accounted for the bulk of industry divestment? Table $5.7$ addresses this question by aggregating the various forms of capacity change (exit, incremental divestment, and capacity addition) into a single summary measure. If all groups cut back by the same average proportion, the total net capacity reduction would be distributed evenly across size classes. However, if large (small) firms divested to a greater extent, then one would observe large (small) firms accounting for a disproportionate share of the total reduction in industry capacity.

To derive the results in table 5.7, a computer program was written to sort firms into the top, middle, and bottom thirds of the industry, based on peak-year capacity, and to keep track of subsequent capacity changes. ${ }^{18}$ The allocation among size classes becomes arbitrary for products where the aggregate reduction in industry capacity was small. To avoid this problem, the mean values reported in table $5.7$ are limited to the 17 products for which the total net reduction in industry capacity exceeded 35 per cent. The figures in table $5.7$ reveal a remarkably balanced pattern of capacity reduction. Very close to one-third of all divestment was undertaken by firms in each of the three size classes.

Despite the fact that incremental reductions were made at on-going plants, most divestments ultimately took the form of plant closures. On average across the 17 products included in table 5.7, capacity fell by 51 per cent between the peak year and late 1986. Plant closures by exiting firms eliminated 26 per cent of peak-year capacity; plant closures by surviving firms eliminated 23 per cent. Various other capacity changes occurred but were less important. Surviving firms expanded some of their remaining plants and cut capacity at others; on average, such expansions added 6 per cent to peak-year capacity while such cutbacks reduced capacity by 8 per cent. Plant sales by exiting firms accounted for 7 per cent of peak-year capacity; these plants were sold to surviving incumbents or new-entrant firms, although many of the plants were ultimately closed.
