The present paper estimates upper-level substitution and new-goods bias in the Korean Consumer Price Index (CPI). It has been estimated that the upper-level substitution bias in the CPI alone increased the inflation rate by 0.51 percentage points per year over the thirteen-year period between...

The use of principal component techniques to estimate approximate factor models with large cross-sectional dimension is now well established. However, recent work by Inklaar, Jacobs and Romp (2003) and Boivin and Ng (2005) has cast some doubt on the importance of a large cross-sectional...

The conventional formula for estimating the extended Gini coefficient is a covariance formula provided by Lerman and Yitzhaki (1989). We suggest an alternative estimator obtained by approximating the Lorenz curve by a series of linear segments. In a Monte Carlo experiment designed to assess the...

The Lorenz curve relates the cumulative proportion of income to the cumulative proportion of population. When a particular functional form of the Lorenz curve is specified it is typically estimated by linear or nonlinear least squares, estimation techniques that have good properties when the...

It is believed that changes in the varieties of an imported product might have effects on the import price index for the product that are similar to the effects of new goods on the cost of living. Recently, a new index number formula that incorporates the effects of new goods has been suggested...

This paper examines and dissects ten popular "suspect" conjectures about exchange rates. The conjectures are the following: (1) Economists know what determines the exchange rate (2) Flexible exchange rates are unstable due to destabilising speculation (3) Flexible exchange rates are excessively...

This paper re-examines the VAR analysis of the price puzzle with regard to the issues of measurement, identification and misspecification. In an empirical analysis conducted for the US economy, we consider alternative measures of economic activity and inflation, alternative assumptions to...

We examine the relationship between inflation and unemployment in the long run,using quarterly US data from 1952 to 2010. Using a band-pass filter approach, we find strong evidence that a positive relationship exists, where inflation leads unemployment by some 3 to 3.5 years, in cycles that last...

This paper considers a central bank with a zero inflation target and a fiscal authority with a differing objective. Examples using calibrated models explore the consequences of the fiscal authority being aware of the central bank's objective. Situations in which the fiscal authority is able to...

Inflation targeting needs to be supplemented by an economic growth target so that central banks will not adopt monetary policy which results in stagnation. There is no guarantee that the economy will move towards full employment by itself when the inflation rate is kept between two to three per...
