Introduction I have spent my whole professional life working in the field of short-term economic analysis. I joined the ISCO (National Institute for the Study of Economic Trends) in the early seventies, and am now working for the ISAE, the Institute for Economic Study and Analysis. This was set up in 1998 by merging the ISCO and the ISPE (Institute for Financial Planning). These developments could potentially lead to the creation in Italy of a body similar to the INSEE (National Economic Studies and Statistical Institute) in France). Building on this personal background, I think it would be most interesting to focus on the fact that, in Italy, changes in what statistical information for short-term economic analysis is used for were followed by changes in the institutions. This observation would seem to imply that the European Union will also have to change its institutions – or at least the way it is organised – if it is to meet the new needs for economic indicators on short-term trends. In my opinion, we might even think of giving Eurostat a role that resembles that of the European Central Bank. I would like to take the situation in Italy as my starting point once again to highlight some of the needs of users of short-term economic indicators. The fact that the producer of short-term statistics and indicators is often the main user is no surprise. But there are many others: economic players, research institutes and the authorities responsible for economic policy. The general public is mainly exposed to short-term economic statistics via the mass media. However, all of these users have different needs, so the ability to provide differentiated short-term economic statistics will become increasingly necessary. 2. Official statistics for short-term analysis As in other countries, Italy’s official statistics providers had long ignored the need for information for short-term economic analysis. This neglect was largely due to the fact that short-term analyses were not considered very important in theoretical terms. When this opinion changed, all the technical and practical difficulties of producing statistics for short-term analysis came to light. -2- INDEX Users demand that statistics be at least quarterly – and monthly if possible. They also want them to be available quickly and they want them to be detailed. In Italy, the gap between the supply of official statistics and the need for data that were suitable for short-term economic analysis had been partially filled by the ISCO. One only needs to think back to the 1980s to remember a time when it was the ISCO that was responsible for constructing indicators for quarterly national accounting and for seasonally adjusting the indices of industrial output. Today ISTAT (the National Statistical Institute) has brought Italian statistics up to speed in this respect, but there are still many other needs that have not been met. For example, some short-term statistics are still not available for the service sector, not to mention the total lack of short-term data at levels other than the national one. Still, the situation in most European countries does not seem to be very different. 3. Business and Consumer Surveys In Italy, the need for short-term economic information could hardly be filled by the ISCO producing a few statistical indicators – not only because of the sheer size of the task, but also because of the specific kind of information needed for short-term economic analysis. Nonetheless it is true that the statistical indicators based on the official data become available much too late to be useful. Moreover, not all variables of interest for short-term economic analysis are easy to include in an official statistical survey. Take the variables that represent the prevalent climate among economic operators and consumers (judgements, intentions, expectations), for example. It is often useful to know not only the trend of a given economic variable, but also the attitude economic players take towards the change. The instrument which solved the problem of obtaining this kind of information is, as mentioned above, the business and consumer survey. A questionnaire can be used to ask economic operators directly for their opinions on the main economic trends, their expectations for the following months and their attitudes towards various important economic phenomena. For a long time, these surveys looked only at industry, and only analysts of short-term economic trends used them It should be mentioned that for quite some time there was considerable opposition to this new instrument, not only in terms of economic theory, but also in terms of statistics. On the one hand, there was a refusal to recognise the usefulness of the study of cyclical -3- INDEX fluctuations. On the other, the results of the surveys were not accepted as being statistically correct. It must be admitted that they do normally refer to a panel of respondents instead of to a random sample. New research has considerably reduced the importance of these criticisms. However, there is no doubt that many users were put off the business and consumer surveys for other reasons, not least of which was the difficulty of reading the results. Since most of the questions in the questionnaire are qualitative, they need to be gathered together as the percentages for each response. The real problem lies not in actually reading the percentages (or of the difference between the two responses), but in the fact that the user often needs to look at the series of previous results to make sense of the latest data. Such evaluations are not always easy. Last spring the ISAE carried out a survey in order to discover how the results of business and consumer surveys were used in industry. Even today, despite the widespread popularity of these surveys, users are often unable to use the results, Only 59% of enterprises replied that they found the business and consumer surveys useful. This problem, which has always existed, has led to research on clearer ways to present the results. In order to present the results of a question in a single piece of data, it was decided to use the difference between the two extremes (or in some cases the sum of the median response and one of the two others if three were required). This also makes it possible to produce effective charts and diagrams. Nonetheless, a single survey normally includes a large number of questions. Users would like to see the whole survey summed up in a single figure. This has not been done, but composite indices have been constructed to sum up groups of responses from individual surveys. The purpose of these indices is not only to sum up the results of several questions to simplify presentation but also to make the most of various responses by bringing them together. There are no fixed criteria for choosing the variables and the type of aggregation to be used to construct a composite index. But selecting a reference variable is important, as is trying to create a composite index that is able to represent short-term movements in the economy. Various composite indices, such as consumer confidence, have been popular with users, which confirms that they meet specific needs. -4- INDEX 4. The requirements of users of short-term economic information Up to now the need for information for short-term economic analysis has been filled mainly by a few official statistics and surveys of business and consumers. As mentioned above, there are many gaps in these sources, and, in many ways, they are extremely inflexible. Therefore the first thing that users need is more and better official statistics and a greater number of business and consumer surveys in order to cover sectors of economic activity and geographical areas that are not currently covered. The surveys have shown themselves to be the most flexible instrument, and they have already made it possible to fill in some of the gaps, for example, short-term economic information for territories. The survey on the manufacturing industry in Italy was developed in such a way that the results were also meaningful at regional level. But users have other needs that are often neglected by the producers of short-term statistical information. I would like to examine some of them with regard to business and consumer surveys. The qualitative results of the surveys can be made simpler, but not simple, to read. There is, however, room to lower the number of qualitative questions. When business and consumer surveys were first set up, convincing economic operators to reply was a major problem, so it was necessary to ask questions that could be answered without too much effort. In addition, the survey’s goal was mainly to detect the direction of change. Today’s users want more: they want to know not only the direction of change, but also its essence. So, in addition to the quantitative indicators derived from the qualitative information in the business and consumer survey, asking for it directly in the surveys is another possibility. In Italy, Confindustria has for many years carried out a monthly survey which collects quantitative data on several variables, including industrial production. These quantitative estimates, which are available before the official statistics are made public, have been markedly successful with users. Of course, those questions which specifically address the attitudes of economic players and their intentions cannot be posed quantitatively. In all probability, new composite indices could be developed for these. In any case, the meaning of these indices should be independent of other, correlated empirical data. In other words, they should not simply serve to forecast other variables. variables that cannot be directly collected. -5- They should indicate other The reliability of composite indices is INDEX normally tested by comparing them to reference variables. But this is a conventional criterion. For certain variables, the survey might be able to detect short-term trends more efficiently than the related empirical data provided in official statistics. Another need users have is related to the widespread presence of econometric models. Many are keen to include some of the variables from the business and consumer surveys in their models. However, this is held back by the difficulty of determining how the qualitative variables from the surveys correspond to the variables from official statistics. Even in the case of a specific variable such as the level of industrial output, it should not be forgotten that the judgements given by enterprises refer to a normal level known only to the respondents. The enterprises are asked to take seasonal variations into account, and of course, each one does so as they see fit. In addition, the survey variables do not usually refer to the average for the reference period, but simply to the end of that period. And when speaking of expectations, the period to which these apply is not always sufficiently clear. Naturally, these are not defects of the business and consumer survey itself. But it would probably still be possible to make some changes to the questionnaires in order to provide more of the accuracy required by those who work with econometric models. Policy-makers also have other requirements for short-term economic information. Generally, their interest in business and consumer surveys is second-hand, as policymakers need certain types of information that point out what action should be taken, while the surveys only provide some of the facts needed to derive that information. An easy way to meet such needs, which I have already put forward elsewhere, would be to carry out short-term economic surveys which focus on policy-makers’ needs. In practise this would mean carrying out a normal business and consumer survey, but doing it in such a way that the various sectors of economic activity would be covered at the same time, and adding a certain number of “ad hoc” questions on subjects of interest to the sectoral questionnaire. The ISAE is already carrying out such a survey on an experimental basis. The survey covers the city of Rome, and began in the third quarter of 1999. So far, it has been successful. The “ad hoc” questions addressed to the enterprises concerned, among other things, the effect of lowering VAT on construction, the existence of a black market for labour, Internet use, the amount of bureaucratic and administrative expense incurred, intentions to change shops’opening hours, etc. -6- INDEX It goes without saying that the most significant aspect of this type of survey is the possibility of analysing the responses to the “ad hoc” questions in the light of the answers to the other questions. 5. Conclusion As a conclusion to this brief overview, I think it may safely be said that, firstly, much remains to be done to broaden the scope and improve the quality of the official quantitative statistics used for short-term economic analysis. And work remains to be done to extend coverage to the sectors and areas that are still not covered by the new business and consumer surveys. The European Union is fulfilling a fundamental role, which is certainly not limited to distributing and harmonising the statistics from the business and consumer surveys. In any case, modifying the business and consumer survey questionnaires in order to better meet users needs is a possibility. And lastly, it might be useful to reflect on the possibility of seeing business and consumer surveys as instruments which are more suited to the needs of policy makers. In future, it will be crucial to be able to manage the production of quantitative statistics, carry out business and consumer surveys and collect the information needed by policy-makers, all at the same time. At the national level, organising the institution along the lines of the INSEE therefore seems to be the best way to develop statistical information for short-term economic analysis. But at the European level, a new role should be devised for Eurostat, modelled on that of the European Central Bank. -7-
