This paper briefly presents the methodology of Distributional National Accounts (DINA), which distributes total national income and total wealth among all individual residents. With DINA, we can estimate inequality statistics and growth by income and wealth groups that are consistent with aggregate growth from National Accounts. This methodology has been recently applied to a number of countries, and the data produced are available from WID.world. The paper summarizes the initial empirical findings. We observe rising top income and wealth shares in nearly all countries in recent decades, but the magnitude of the increase varies substantially, thereby suggesting that different country-specific institutions and policies matter. We combine countries' statistics to estimate global inequality since 1980. Global inequality has increased since 1980 in spite of the catching up of large emerging countries like China and India. This has been driven by the income growth of top world earners.

Résumé – 2016, a revu fortement à la la croissance annuelle du PIB pour l’année 2015, de 7 % à 26 %. Cette révision ne correspond pas à une hausse de l’emploi ni à une accumulation de capital physique, mais à la relocalisation d’actifs immatériels existants en Irlande par des multinationales. L’article présente de façon détaillée l’effet de ces relocalisations sur le PIB et la balance des paiements irlandais en 2015. Nous questionnons la nécessité de modifier les normes comptables qui définissent les agrégats macroéconomiques ou le cadre de l’analyse économique. Nous concluons à la nécessité d’un effort pour adapter et réviser les normes de la comptabilité nationale afin d’appréhender les transactions internationales des multinationales, particulièrement en clarifiant le concept de propriété économique de la production et des produits de la propriété intellectuelle, puis en facilitant sa mise en œuvre. Abstract – In July 2016, the Irish statistical institute significantly revised GDP annual growth in 2015 from 7% to 26%. This revision does not correspond to a similar increase in employment nor in the accumulation of new physical capital, but to the relocation of preexisting intangible assets by multinationals to Ireland. This article provides a comprehensive depiction of the effects of these relocations on the Irish GDP and balance of payments in 2015. We question the need to change the accounting standards defining the macroeconomic aggregates and the framework for economic analysis. We conclude that an effort to adapt and revamp the standards of national accounts is thus necessary to achieve a consistent recording of multinationals’ transactions, cru cially by clarifying the concept of economic ownership over production and intellectual property and then by facilitating its implementation.

[eng] The idea that competitive balance increases the utility of fans, and therefore their spending and the revenue of professional clubs, lies at the heart of sports economics in general and the economics of football in particular. This notion of competitive balance is often invoked to explain the decisions of professional leagues to change the rules of competitions or the distribution of TV rights. However, the empirical literature shows that the relationship between competitive balance and fan demand is far from obvious. In this paper, we examine the idea of competitive balance as perceived by football fans. In the case of Ligue 1, it is mainly explained by medium- and long-term uncertainty, while in the case of the Champions League it is more a matter of long-term suspense. But uncertainty over the outcome is far from being the only factor explaining the demand for football since around 30% of fans report that they would always be willing to attend or watch games even in the hypothetical case that there is no suspense left.

[eng] In this survey paper, we argue that the effects of artificial intelligence (AI) and automation on growth and employment depend to a large extent on institutions and policies. We develop a two-fold analysis. In a first section, we survey the most recent literature to show that AI can spur growth by replacing labor by capital, both in the production of goods and services and in the production of ideas. Yet, we argue that AI may inhibit growth if combined with inappropriate competition policy. In a second section, we discuss the effect of robotization on employment in France over the 1994-2014 period. Based on our empirical analysis on French data, we first show that robotization reduces aggregate employment at the employment zone level, and second that non-educated workers are more negatively affected by robotization than educated workers. This finding suggests that inappropriate labor market and education policies reduce the positive impact that AI and automation could have on employment.

[eng] In France since the 1970s, the growth in labour force has been driven largely by that of women’s participation in the labour market and the fact that they interrupt their careers less often after motherhood. Their level of education has also risen considerably, and they have, on average, been more highly educated than men since the 1990s. But these developments did not result in reducing the gender pay gap to what might have been expected: the average hourly wage gap in the private sector has remained around 20% since the mid-1990s. In this average gap, the share explained by differences in human capital (education, experience) was cancelled out and even reversed between 1968 and 2015. The persistence of the wage gap now appears to be mainly linked to the consequences of motherhood. A child’s arrival causes mothers a loss of annual income largely due to adjustments in their working time. This penalty is higher for mothers whose wages are at the bottom of the wage distribution.

With the advent of scanner and web scraped data, “big data” sources are increasingly finding their way into official statistics. This second part of the special issue on “Big Data and Statistics” is devoted to developments in the use of these data for consumer price indices. To what extent are big data different to more traditional data sources such as the collection of prices in the field, and how do they change the process of producing consumer price indices? The four papers in this special issue address these questions by means of the experiences gained in the statistical offices of France, Sweden and the Netherlands. This introduction puts them into perspective vis-a-vis the value chain of scanner and web scraped data and looks at some further issues for research in this field.

[eng] When consumers pay for their purchases at the store checkout, the barcodes (also known as GTINs) of the goods purchased are scanned, recording quantities and the prices linked to each barcode in the process. Scanner data present an opportunity for use in constructing consumer price indices, which could supersede the use of survey data. Based on the existing concept of consumer price indices, the volume and new types of information provided by scanner datasets raise a number of new methodological questions, in particular in relation to price aggregation to produce indices, handling quality adjustments, classifying goods by homogeneous consumption segment and dealing with product relaunches and promotions. This article looks at how these questions have been addressed in France.

[eng] Statistical institutes are considering web scraping of online prices of consumer goods as a feasible alternative to scanner data. The lack of transaction data generates the question whether web scraped data are suited for price index calculation. This article investigates this question by comparing price indices based on web scraped and scanner data for clothing and footwear in the same webshop. Scanner data and web scraped prices are often equal, with the latter being slightly higher on average. Numbers of web scraped product prices and products sold show remarkably high correlations. Given the high churn rates of clothing products, a multilateral method (Geary-Khamis) was used to calculate price indices. For 16 product categories, the indices show small overall differences between the two data sources, with year on year indices differing only by 0.3 percentage point at COICOP level (men’s and women's clothing). It remains to be investigated whether such promising results for web scraped data will also be found for other retailers.

[eng] This study is based on scanner data from large retailers sent daily to Insee in 2013. Its aim is to calculate indices that measure differences in consumer price levels between different areas of metropolitan France, focusing specifically on food products sold in supermarkets. A hedonic index based on the regression of the product price on barcode and territory dummies is developed. Several assessments are carried out over different weeks, with one week of data already providing a great degree of accuracy. The dispersion of price levels between regions or large conurbations is limited and, for the most part, robust to the choice of week. The highest prices are found in the Paris region and Corsica, with a magnitude of differences in the order of a few percentage points. A comparison of the new findings with research conducted by Insee between 1970 and 2000 shows that differences in food prices across different areas of metropolitan France are essentially structural and change little over time.
