4. The 2007-2012 Outlook for Sheet Metal Roof Ventilators and Louvers and Dampers for Heating, Ventilation, and Air-Conditioning in Japan

Description

This study covers the latent demand outlook for sheet metal roof ventilators and louvers and dampers for heating, ventilation, and air-conditioning across the prefectures and cities of Japan. Latent demand (in millions of U.S. dollars), or potential industry earnings (P.I.E.) estimates are given across some 1,000 cities in Japan. For each city in question, the percent share the city is of its prefecture and of Japan is reported. These comparative benchmarks allow the reader to quickly gauge a city vis--vis others. This statistical approach can prove very useful to distribution and/or sales force strategies. Using econometric models which project fundamental economic dynamics within each prefecture and city, latent demand estimates are created for sheet metal roof ventilators and louvers and dampers for heating, ventilation, and air-conditioning. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study also does not consider short-term cyclicalities that might affect realized sales. The study, therefore, is strategic in nature, taking an aggregate and long-run view, irrespective of the players or products involved.

10. The 2019-2024 World Outlook for Sheet Metal Roof Ventilators and Louvers and Dampers for Heating, Ventilation, and Air-Conditioning

Description

This study covers the world outlook for sheet metal roof ventilators and louvers and dampers for heating, ventilation, and air-conditioning across more than 190 countries. For each year reported, estimates are given for the latent demand, or potential industry earnings (P.I.E.), for the country in question (in millions of U.S. dollars), the percent share the country is of the region, and of the globe. These comparative benchmarks allow the reader to quickly gauge a country vis--vis others. Using econometric models which project fundamental economic dynamics within each country and across countries, latent demand estimates are created. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study also does not consider short-term cyclicalities that might affect realized sales. The study, therefore, is strategic in nature, taking an aggregate and long-run view, irrespective of the players or products involved. This study does not report actual sales data (which are simply unavailable, in a comparable or consistent manner in virtually all of the countries of the world). This study gives, however, my estimates for the worldwide latent demand, or the P.I.E., for sheet metal roof ventilators and louvers and dampers for heating, ventilation, and air-conditioning. It also shows how the P.I.E. is divided across the world's regional and national markets. For each country, I also show my estimates of how the P.I.E. grows over time (positive or negative growth). In order to make these estimates, a multi-stage methodology was employed that is often taught in courses on international strategic planning at graduate schools of business.
