Doing business in Poland: What U.S. managers need to know

Poland has been and continues to be the leader of the transition economies of Eastern Europe. This study provides an in‐depth look at the ongoing economic, legal, and administrative policies of the Polish government in laying the ground‐work for a free‐market society. With the smaller business in mind, we first examine how the government of Poland moved decisively to lay the cornerstone for a private‐sector economy. Next, we demonstrate how Poland redirected its political and legal processes for long‐term global business. Finally, we describe what the U.S. government is doing to help Poland become a better trading partner and what this means to interested American firms. While there are many deep‐seated positive changes throughout Poland as it becomes a more significant global business player, there also are many challenges that must be understood by interested U.S. businesses if their investments in Poland are to be successful. © 2004 Wiley Periodicals, Inc.     

Does Religion Matter? A Comparison Study of the Ethical Beliefs of Marketing Students of Religious and Secular Universities in Japan

This study was designed to examine the determinants of and differences between the ethical beliefs of two groups of Japanese students in religious and secular universities. Multiple regression analysis revealed that students of the Japanese religious university perceived that young, male, relativistic, and opportunistic students tended to behave less ethically than did older, female, and idealistic students. Students of the Japanese secular university perceived that male, achievement-oriented, and opportunistic students tended to behave less ethically than did female and experience-oriented students. Opportunism was found to be one of the most important determinants in explaining misconduct. Multivariate analysis of variance (MANOVA) and multiple discriminant analysis (MDA) revealed that students of the Japanese secular university tended to score higher on achievement and humanism, and lower on theism and positivism than did students of the Japanese religious university. In addition, students of the Japanese secular university were somewhat more sensitive to academic dishonesty practices than were students of the Japanese religious university.     

The Home Improvement,Maintenance, and Repair Industry

Spending on existing housing is important not only for the building materials, building products, and construction markets but also for the macroeconomy. It accounts for about half of total spending on housing capital. The new construction, home improvement, maintenance, and repair markets use overlapping distribution channels, labor, and capital inputs. The various segments of the housing industry touch many other industries and exhibit different patterns over the course of the business cycle. Understanding the unique characteristics of these segments helps business economists and macroeconomists in planning and interpreting changes in the economy as well as estimating better forecasting models.
