Transcription

1 Market Dynamcs and Productvty n Japanese Retal Industry n the late 1990s Toshyuk Matsuura, Research Insttute of Economy, Trade and Industry Kazuyuk Motohash, Unversty of Tokyo & Research Insttute of Economy, Trade and Industry

2 Ponts at ssue Motvaton Why s the performance so low? Does market selecton mechansm worked? Objectve To examne whether Japanese retals sector s n process of transformaton. To lnk the aggregated productvty growth wth mcro productvty growth.

3 Comparson of productvty between Japan and US - Mcknsey Global Insttute -

4 Reason for the productvty gap between Japan and US Why do unproductve stores reman n market? Entry barrer for Large scale stores Large scale stores low Ext barrer for Small stores Tax reducton and allowance for the owner of Pap and Mum type famly busnesses.

5 The falure of the Natural Selecton Mechansm Nshmura, Nakajma and Kyota[2002] Comparson of frm-level productvty among entres, contnues, and exts After 1996, productvty of exts are better than others. Has Market selecton mechansm worked well?

6 The Methodology Overvew of the trends n turnover by entry and ext of establshment Transton of productvty rankng wth longtudnal dataset. Productvty decomposton Regresson analyss
