We build a single‐country, two‐city, model with nominal rigidities and transport costs which
predicts that variation of LOP deviations is lower for goods with infrequent price adjustment …

US micro price data at the city level suggests that both the volatility and the persistence of
law of one price deviations are rising in the distance between US cities. A standard two-city …

This paper investigates the degree of inflation persistence across regions in Portugal by
analyzing the Consumer Price Index (CPI) growth rates for NUTS II regions. The study …

This paper proposes a model-free approach to analyze panel data with heterogeneous
dynamic structures across observational units. We first compute the sample mean …

We examine the impact of physical distance, language, and religion on Law of One Price
(LOP) deviations across interwar Canadian and modern Nigerian cities. The data comprise …

We empirically analyse regional inflation using data from Japan where there is no regulation
to impede the free movement of labour, capital, goods and services across regions. In …

This research investigates the convergence of local consumer price indexes (CPIs) within
Japan using a pairwise approach. Annual and monthly series of the general and …

Purchasing power parity suggests that international price ratios for identical goods should
approximate nominal exchange rates for the currencies in which the prices are …

Using 25 years of monthly data on individual Japanese retail prices, we study the behavior
of product-specific Law of One Price (LOP) deviations. Individual tradable products …
