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 a vacancy rate. We argue that the indicators should be (macro-)consistent, meaning that...

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;...

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...

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...

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...

This study addresses a significant gap in the existing literature by conducting a comprehensive systematic review of the art market over the past 50 years, utilizing big data analysis and bibliometric methods. Through descriptive statistical analysis, we gained insights into research trends,...

This Staff Memo presents an indicator used for monitoring and forecasting inflation at Norges Bank. The indicator is designed to capture international price impulses that impact the input costs of domestic firms. Our analysis indicates that the marked increase in the cost of imported...

The FDZ Ruhr at RWI provides price indices for apartments and houses (rentals and sales) in Germany starting in 2008. The price indices are based on the real estate dataset RWI-GEO-RED, which combines real estate listings from ImmoScout24. We perform three types of hedonic regressions to allow...
