We develop a statistical-methodological framework for a set of core commercial real estate market indicators, which consists of a market price index, a gross rent index, and a net rental yield index as well a vacancy rate. We argue that the indicators should be (macro-)consistent, meaning that...

Although the Ethiopian government is engaged in a process of modernization and making major financial reforms, there remains lack of solid financial tool that could assist market participants in analyzing the agricultural commodity market positions. Similarly, agricultural policy lacks...

Accurate, real-time measurements of price index changes using electronic records are essential for tracking inflation and productivity in today's economic environment. We develop empirical hedonic models that can process large amounts of unstructured product data (text, images, prices,...

We develop a statistical‐methodological framework for a set of core commercial real estate market indicators, which consists of a market price index, a gross rent index, and a net rental yield index, as well as a vacancy rate. We argue that the indicators should be (macro‐)consistent,...

This study presents a comprehensive bibliometric and systematic literature review analysis of the literature on the Big Mac Index (BMI) to identify its foundational aspects and summarize key findings. The BMI, an informal measure of purchasing power parity, has garnered scholarly interest in...

We introduce a novel, non-parametric approach for estimating house price indices that capture heterogeneous price developments independently of strict functional form assumptions. Utilizing the potential outcomes framework, our approach employs causal forests to effectively address changes in...

The consumer price index (CPI) plays a critical role in measuring inflation. Recent inflation trends, however, have raised questions about its accuracy. This paper evaluates several of these critiques, including that the CPI fails to keep up with rapid changes in consumer expenditure patterns;...

The FDZ Ruhr at RWI provides regional price indices for apartments and houses (rentals and sales) in Germany since 2008 through the RWI-GEO-REDX dataset, based on property listings from ImmoScout24 (RWI-GEO-RED). RWI-GEO-REDX stands out for its high spatial resolution: the exact location of each...

This textbook offers a comprehensive yet concise introduction to the theory behind price indices, covering the basics, historical background, necessary mathematical foundations, and contemporary cutting-edge theories. For those looking to study price indices, the most commonly used resources...

A chained price index is said to suffer from chain drift bias if it indicates an overall price change, even though the prices and quantities in the current period have reverted back to their levels of the base period. The empirical relevance of this bias is well documented in studies that apply...

The FDZ Ruhr at RWI offers price indices for apartments and houses (rentals and sales) in Germany, commencing in 2008. The price indices are derived from the RWI-GEO-RED real estate dataset, which integrates real estate listings from ImmoScout24. Three types of hedonic regressions are performed...
