Introduction

In today’s fast-paced global economy, timely and accurate economic forecasts are crucial for informed decision-making. Traditional economic indicators are often released with a significant lag, making it challenging to assess current economic conditions. Nowcasting, a technique that utilizes high-frequency data and advanced statistical methods, offers a solution by providing real-time estimates of key economic variables. This course is designed to provide participants with a comprehensive understanding of nowcasting and high-frequency data analysis, enabling them to effectively monitor and forecast economic trends. Participants will learn how to gather, clean, and analyze high-frequency data from various sources, including financial markets, internet search activity, and social media. They will also gain hands-on experience in building and evaluating nowcasting models using state-of-the-art econometric techniques. The course will cover a wide range of topics, including data visualization, time series analysis, and forecast evaluation.
