Facts & Figures for the chemical industry

June 9, 1986 C&EN

Reflecting the sluggish performance of the overall economy, the U.S. chemical industry in 1985 experienced a year of moderate growth but mixed financial results. For the industry as a whole, production increased, with plastics and a handful of specialty products setting the pace. On the other hand, in such major areas as inorganic chemicals, man-made fibers, and especially agricultural chemicals, 1985 was a dull if not downright depressed year.

Financially, the record was even more confused. In a widespread effort to revamp the industry's structure and enhance operating efficiency, many companies, both large and small, undertook a dizzying assortment of asset write-downs and spinoffs, staff reduction programs, and various accounting changes. The resulting special charges and credits drastically affected 1985 income statements for the industry as a whole,

Those moves, however, probably will set the stage for a better record in 1986. Output is likely to edge higher again, albeit rather shakily. Profits already are looking stronger. And the weaker U.S. dollar prom­ ises relief from one long-standing problem by improving the compet­ itive position of U.S. chemical pro­ ducers against their counterparts overseas. The data presented on the fol­ lowing pages of C&EN's annual Facts & Figures issue illustrate these trends statistically, providing a mea­ sure of the chemical industry's re­ cent performance in the U.S. and, to a lesser extent, in several other important chemical-producing na­ tions. The data pulled together here come from a diverse variety of sources, such as government agen­ cies, trade associations, and inter­ national organizations, as well as the individual companies that com­ prise the complex industry. The data, in many cases, have been used by C&EN's staff to develop analytical measures and comparisons that help put the industry's recent results into better perspective.

at a glance Section One: Production In the U.S. chemical industry, out­ put continued to expand in 1985. But the pace slowed markedly from the year before. And for many sec­ tors of the industry, production ac­ tually fell a bit from the 1984 level. Plastics was a strong area. On the other hand, man-made fibers had a mediocre year, as imports cut into U.S. demand. A poor year for U.S. farmers, meanwhile, resulted in a decline in production of agricultur­ al chemicals. Page 34 Section Two: Finance Earnings declined for U.S. chemical companies in 1985, after three years of growth, as sales stagnated, prices came under pressure, and chemicals produced abroad cut into markets for made-in-America products. Cap­ ital spending, meanwhile, contin­ ues to expand, although the increase this year is likely to be slim. Budgets for R&D also are showing little or no prospects for increases this year. Page 46

Section Three: Employment The number of workers employed in the chemical industry declined last year, after rising in 1984, to the lowest level in the past decade. But with output up slightly, the produc­ tivity of the industry's work force improved from the year before and unit labor costs were down. Page 61 Section Four: Foreign Trade World trade in chemicals has slipped from its peak level of 1984, largely because of lower imports on the part of underdeveloped nations. And the long-standing U.S. trade surplus in chemicals continued to shrink, as imports rose but exports, hurt by a strong U.S. dollar, dwin­ dled. Page 66 Section Five: Foreign Chemical Industries Outside the U.S., 1985 was a mixture of good and bad for chemical pro­ ducers. Profitability generally was up for chemical companies in West Europe. However, earnings deterio­ rated in Japan's petrochemical in­ dustry, and the outlook remains poor there. Unsatisfactory prices eroded the profits of chemical com­ panies in Canada. Page 70

Employment in the U.S. Chemical Industry

Chemical work force drops steeply in 1985 In 1985, the number of workers employed by the U.S. chemical industry fell to about 1,042,000, the lowest level of employment since 1975. A steady decline throughout 1985 and in the early months of 1986 wiped out the modest recovery that occurred in 1984. Employment also dropped again in the petroleum in­ dustry last year, but rubber manufacturers continued a trend toward higher numbers of workers. Despite the overall downturn, two chemical sec­ tors—soaps, cleaners, and toilet goods and paints and allied products—added a modest number of employees in 1985. Employment held steady in the industrial in­ organic and organic chemicals segments. How­ ever, producers of plastics, synthetics, drugs, and agricultural chemicals trimmed their work forces. Major chemical companies, as a group, added em­ ployees in 1985. Notable among the giant firms were Dow Chemical, which increased employment last year after several years of cuts, and Union Carbide, which cut back sharply on the number of its workers.

Productivity in the U.S. chemical in­ dustry improved in 1985, but most of the increase came as a result of falling employment rather than from increased production. And in spite of the improvement, produc­ tivity gains for manufacturers of chemicals and allied products lagged those for all manufacturing industries. In 1985, production of chemicals increased 3.4% but work hours in the chemical industry declined 2.4%. As a result, productivity in­

creased 5.9%, compared with a 4.0% increase in 1984. At the same time, chemical pro­ ducers were holding labor costs in check. Hourly production wages in 1985 increased just 4.3% over the year before. Consequently, unit la­ bor costs fell to their lowest level since 1981. Unit labor costs in 1985 were down 1.5%, compared with a 0.7% rise in 1984 over the previous year. However, for all manufacturing, improvements in the productivity

scene was even better. For all manu­ facturing, productivity had in­ creased 9.2% on a 6.7% rise in pro­ duction and a 2.2% fall in workhours. In 1984, productivity for all manufacturing was up only 1.5% from the year before. Like productivity, unit labor costs for all manufacturing outperformed chemicals, falling 5.4% from the year before on a 3.3% rise in hourly production wages. In 1984, unit la­ bor costs for all manufacturing were up 2.3%.

How to use a bacterium in the battle for bigger crops Plants grow by photosynthesis—by converting energy from sunlight into chemical energy. With better understanding of photosynthesis, crops that use light more efficiently might be developed, shortening growth cycles and increasing yield. The battle against world hunger might be won. Studying photosynthesis on field crops is time-consuming and expensive. At the University of Illinois, scientists use a simpler model of photosynthesis as a stand-in: Rhodopseudomonas sphaeroides, bacteria capable of the same light energy conversion process as plants. University microbiologists grow mutant strains of R. sphaeroides overnight, then measure their altered photosynthesis capability with a Cary 2390 UV-Vis-NIR Spectrophotometer. The secrets of more efficient photosynthesis are beginning to unravel. Some day soon, a tiny bacterium may teach us how to produce bumper crops. For details about the Cary 2200/2300 UV-Vis-NIR Spectrophotometer systems and other analytical instrumentation,

World chemical trade cools off World chemical trade cooled off last year. After a 7.5% jump in 1984, world chemical exports slipped nearly 3% to an estimated $142.5 billion. World trade numbers, however, have to be taken with a grain of salt. To determine a total world chemi­ cal export figure, it's necessary to go to several differ­ ent sources, including the United Nations (always two years late with its data), the Organization for Economic Cooperation & Development (always one year late), the European Economic Community, and several individ­ ual countries. The big problem, of course, lies in the way these various organizations use exchange rates to convert foreign currencies into U.S. dollars. Although currency conversion always is a problem, in the past few years, and especially last year, the prob­ lem was compounded because the exchange rate for U.S. dollars fluctuated wildly.

U.S. TOTAL TRADE BALANCE: Slips further into the red $ Billions

Total exports Total imports Trade balance

Nevertheless, it seems apparent that several major chemical exporters suffered setbacks last year. Chemi­ cal exports from EEC, for one thing, were down. EEC exports to the U.S., however, increased a healthy 11% last year. The losses in chemical exports, then, had to come from developing country markets, just as was the case for exports by U.S. chemical producers. U.S. chemical exports dipped 2% last year to $21.5 billion. Shipments held up adequately to such devel­ oped markets as Western Europe, Japan, and Canada. But important markets in developing areas, particular­ ly Latin America and Asia, weakened considerably. Many countries in those regions cut back on imports to cope with their own domestic economic problems. Meanwhile, the expected improvement in U.S. chemi­ cal exports as a result of the weakening dollar had not yet taken hold.

Foreign Chemical Industries—Western Europe

European chemical companies had another good year in 1985. West Germany's Bayer retained its position as top in total sales. BASF moved into the number two slot past Hoechst, which now stands at number three. Profit margins improved for just about every company. Laporte Industries achieved a creditable 10%. CibaGeigy and Fisons earned about 8% on sales. Montedison experienced the biggest turnaround, netting a profit for the first time in a decade. The changing value of the U.S. dollar is causing concern to European business executives. In 1985 as a whole, the dollar gained in strength against West European currencies. But about midyear a change set in, and the dollar began to weaken. The trend is continuing. As a result, European chemical producers face stiffer price competition from their U.S. counterparts.

The Normalization Pairing A scientist at the General Motors Research Laboratories has developed a new method for accurately determining the effectiveness of safety belts in preventing traffic fatalities. The approach may be used to answer a wide variety of questions using data bases that lack conventional measures of exposure.

HERE IS A serious problem that researchers often en­ counter when trying to analyze large collections of information. It is the problem of measuring exposure. Though a collection of data may contain a large number of cases, and though the facts in each case may be highly detailed, there may be no way of comparing events selected for in­ clusion in the collection against the normal occurrence of similar events in the world at large. One such data base is the Fatal Accident Reporting System (FARS) maintained by the U.S. Department of Transportations National Highway Traffic Safety Administration. FARS details all fatal accidents in the U.S. since January 1, 1975—more than 300,000 crashes. However, it lacks an explicit measure of exposure. FARS contains, for example, the number of fatalities classified by safety belt use. But fatalities among users depend on two considerations: first, the effectiveness of safety belts; and second, the crash involvement

differences between users and nonusers—that is, the exposure of belt users to crash involvement. If crash involvement were independent of belt use, it would be a simple matter to calculate the effectiveness of safety belts in preventing fatalities. How­ ever, belted drivers have fewer crashes, and the crashes they do have tend to be of lower average severity than those of unbelted drivers. Now a scientist at the General Motors Research Laboratories has developed an approach to drawing inferences from FARS using only the information contained in the file. Dr. Leonard Evans has designed a method for comparing the effects of isolated characteristics by using two sets of crashes. In each set, a subject occupant is paired with an other occupant. In the first set, the subject exhibits the characteristic to be stud­ ied; in the second, the subject does not. The other occupant is chosen to have similar characteristics in both sets of crashes (e.g. always unbelted), and thereby acts as a measure of exposure. To illustrate the workings of the method of double-pair comparison, Dr. Evans first applied it to a study of the effects of safety belt use on fatality risk. He could define the effectiveness of safety belts in terms of the ratio: R

where N' is the number of crashes per year by unbelted drivers, s is crash severity, fu(s) is the probability that a crash involving an unbelted driver has a severity s, qi )u (s) is the probability that an unbelted driver will become a fatality in a crash of severity s, and q, )h (s) is the probability that a belted driver will become a fatality in a crash of severity s. R,riK. is a ratio of new to

old fatalities—assuming a formerly unbelted population became a belted population, with nothing else changing. But while Nu, the number of unbelted driver fatalities, can be determined from the FARS data, Nb, the number of these who would still have been fatalities had they been wearing safety belts, clearly is not coded in the data base. Dr. Evans applied the double-pair comparison method to determine a quantity, R, that would, under plausible assumptions, accurately estimate RtriK.. Figure 2 shows the pattern of the first application. In it, one set of crashes paired belted drivers and accompanying unbelted front-seat passengers, generating a ratio, r lt of belted driver fatalities per unbelted passenger fatality. The second set paired unbelted drivers with unbelted front-seat passengers, leading to a ratio, r2, of unbelted driver fatalities per unbelted passenger fatality. This yields a value of R = rllr2 as a measure of safety-belt effectiveness.

I

N ADDITION to calculating R for driver subjects using front-seat passenger others, effectiveness was also calculated for right-front passenger subjects using driver others. Additional calculations were made pairing driver or right-front passenger subjects with passengers in any other seating position. Figure 1 reflects the synthesis of these estimates. Estimates 1 and 2 represent subject and other occupants disaggregated into three age categories and averaged. Estimates 3 and 4 represent pairings of subjects with occupants in other seating positions and averaged. In all, Dr. Evans calculated 46 estimates of R. The weighted average of these gives a safety-belt effectiveness of (41.4 ± 3.8)%. This should be an accurate estimate whenever the

distribution of severities is the same for both sets of crashes in each double-pair comparison. Moreover, a formal analysis showed rxlr2 to be an accurate estimate of Rtrm. under much less stringent restrictions. Even when the distributions of crash severity differ for belted and unbelted drivers, Dr. Evans concluded that the simple ratio R = rllr2 = nd/me is indeed an accurate estimate of safety-belt effectiveness. Dr. Evans' confidence in the method rests on some key assumptions. But, as he points out: 'One of the beauties of the method is its ability to remove the biasing effects of confounding interactions that may undermine those assumptions. It is necessary only to disaggregate occupants into different categories of the suspect variable. "Because of bias elimination, and the ability to create a measure of exposure, the method of double-pair comparison lends itself to a broad range of investigations. We can estimate, for example, fatality risk as a function of helmet use by motorcyclists, or safety-belt effectiveness in different accident types. More broadly, we can estimate fatality risk as a function of age, sex, or alcohol use. We may even have revealed a trend in trauma response, in general, as a function of sex and age."
