This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...

The paper analyses the reasons for Japan’s persistently low inflation since the bursting of the Japanese bubble economy (low inflation conundrum). It is shown that Japan experienced a structural break from a high-growth period with relatively high inflation to a low-growth period with...

The Hamilton method for estimating CPI bias is simple, intuitive, and has been widely adopted. We show that the method confiates CPI bias with variation in cost-of-living across income levels. Assuming a single price index across the income distribution is inconsistent with the downward sloping...

We examine the relationship between inflation and fiscal sustainability with a two-step approach. In the first step, we estimate to estimate a country-specific time-varying measure of fiscal sustainability using the fiscal reaction function. This function captures the response of the primary...

This paper uses the endogenous regime switching model with dynamic feedback and interactions developed by Chang et al. (2023) to estimate global food price mean and volatility indicators, the latter measuring uncertainty and risk in the global food market. Both are then included in structural...

This paper uses the European Commission's Consumer Survey to assess whether inflation expectations have converged and whether inflation uncertainty has diminished following the introduction of the Euro in Europe. Consumers? responses to the survey suggest that inflation expectations depend more...

Changes in product characteristics on the extensive margin are an important and hitherto neglected dimension of quality change. Standard techniques for quality-adjusting price indices cannot handle such changes satisfactorily, which leads to an economically and statistically significant bias in...

This paper evaluates alternative indicators of global economic activity and other market fundamentals in terms of their usefulness for forecasting real oil prices and global petroleum consumption. We find that world industrial production is one of the most useful indicators that has been...

We present a novel approach for measuring democracy based on Support Vector Machines, a mathematical algorithm for pattern recognition. The Support Vector Machines Democracy Index (SVMDI) is continuously on the 0-1-interval and enables a very detailed measurement of democracy for 188 countries...

It is well known that people’s consumption patterns change with income. Relative price changes therefore affect rich and poor consumers differently. Yet, the standard price indices are not income-specific and hence, the use of these mask these differences in cost-of-living. In this paper, we...
