The present paper develops Adaptive Trees, a new machine learning approach specifically designed for economic forecasting. Economic forecasting is made difficult by economic complexity, which implies non-linearities (multiple interactions and discontinuities) and unknown structural changes (the...

This paper introduces the OECD Weekly Tracker of economic activity for 46 OECD and G20 countries using Google Trends search data. The Tracker performs well in pseudo-real time simulations including around the COVID-19 crisis. The underlying model adds to the previous Google Trends literature in...

Physical inactivity and sedentary behaviours have been rising throughout the OECD in recent decades. Lack of physical activity and excessive sedentary behaviour are well-known risk factors for non-communicable diseases, such as heart diseases, stroke, diabetes, and osteoporosis. As such,...

The Better Life Index was introduced by the OECD as a tool to chart the multi-dimensional well-being of OECD member countries, Brazil and the Russian Federation. However, the Better Life Index relies only on aggregate country-level indicators, and hence is insensitive to how multi-dimensional...

Since 2009, the OECD Development Centre has been publishing the Social Institutions and Gender Index (SIGI), a cross-country measure of gender-based discrimination in social institutions (formal and informal laws, social norms and practices). This working paper presents the conceptual and...

This paper sets out a framework to estimate quality-adjusted price levels and price changes for fixed broadband services in OECD countries. We extend and adapt existing hedonic frameworks for international and interarea comparisons and consider the extended country product dummy approach....

The OECD Better Life Index is an interactive composite index that aggregates average measures of country’s well-being outcomes through weights defined by users. This paper studies these weights by analysing the responses given by close to 130 000 users since 2011 to date. The paper has three...

The effect on the household consumption price index from possible sources of error in capturing digital products depends on the weight of the affected products. To calculate upper bounds for this effect, we apply weights based on the average structure of household consumption in OECD countries...

China’s exceptional economic expansion has led to rising energy demand and pollution as well as other environmental pressures. Strong efforts by the government have moderated emissions of some types of air and water pollution from high levels but others, including greenhouse gas emissions,...

Patent data provide an increasingly used means to analyse innovation performance worldwide including in countries with incomplete data coverage, such as some developing countries. This paper discusses the specific issues associated with using patent data for measuring and analysing innovation in...
