AbstractTo control for product quality and eliminate the exchange rate volatility effect, we use the Japanese regional data to study the Penn effect -the positive relationship between price and income levels. Similarly to what is widely documented with international data, the price and income levels exhibit significant positive association across the Japanese prefectures. Furthermore, the intra-Japan Penn effect is driven essentially by prices of nontradables. The effect is also found stronger among rich prefectures than poor ones, as is the case with the international data. In explaining the Penn effect within Japan, we find that the measures of sectoral productivity do not behave in the way suggested by the Balassa-Samuelson hypothesis. On the other hand, the population density variable that captures the agglomeration effect offers a good explanatory power.JEL-Code: F310, F340, F360.Keywords: agglomeration effect, Penn effect, sectoral productivity differential, tradables and non-tradables, population density.

IntroductionThe Penn effect refers to the robust empirical positive association between national price levels and real per capita incomes that is documented by a series of Penn studies including Lipsey (1983, 1987), Kravis, Heston and Summers (1978), and Summers and Heston (1991). That is, compared with poor countries, rich countries tend to have higher price levels. The positive association between income and price levels is considered as a fundamental fact of economics (Samuelson, 1994) and a conventional wisdom in international macroeconomics (Bergin 2009).Since the early Penn studies, the internationally comparable income and output data The current exercise investigates the price and income relationship using intra-Japan data. The restrictions on trade and labor mobility between countries are quite different from those between regions in Japan. Thus, it will be of interest to investigate if the Penn effect usually documented within the international context could be extended to data within a country.Beside an alternative perspective, the use of Japanese data alleviates some concerns about data incompatibility and its implications for studying the income effect on prices. For instance, the Japanese regional price data examined in the following sections are for products that are quite similar in both quality ...
