A THEORETICAL DISCUSSION REVIEWS PERTINENT LITERATURE AND POINTS OUT AREAS FOR RESEARCH (DEFINITION OF BUSINESS CRIME, CHARACTERIZATION OF WHITE COLLAR OFFENDERS, AND ANALYSIS OF THE SOCIAL REACTION). CONNECTIONS BETWEEN THE BUSINESS WORLD AND ORGANIZED CRIME IN TERMS OF OPERATIONAL METHODS AND ACTUAL COOPERATIVE EFFORTS ARE DETAILED. A FURTHER STUDY IS DEVOTED TO THE INFORMAL TECHNIQUES EMPLOYED BY BANK MANAGERS IN DEALING WITH BAD CHECKS IN BOTH CITIES AND RURAL AREAS. A JUDGE INVOLVED IN THE INVESTIGATION OF CONSTRUCTION INDUSTRY CORRUPTION REFLECTS ON THE CRISIS OF VALUES AND THE EFFECTS OF ORGANIZED CRIME AS FACTORS CONTRIBUTING TO WHITE-COLLAR OFFENSES. THE CHARACTERISTICS USED IN DEFINING TYPES OF ECONOMIC CRIMES, VICTIMS, AND CRIMINALS; THE MAKE-UP OF THE SPECIAL POLICE UNIT FOR WHITE-COLLAR CRIME; TECHNIQUES FOR INVESTIGATION; AND DIFFICULTIES ASSOCIATED WITH SUCH INVESTIGATIONS ARE OUTLINED BY A MEMBER OF THE QUEBEC POLICE DEPARTMENT. FINALLY, THE BOOK OF RICHARD DESMAIS ON THE CRIMINAL DUBOIS CLAN IS DESCRIBED TO SHOW HOW THE ALLIANCE BETWEEN PUBLIC AUTHORITIES AND ORGANIZED CRIME INTERFERES WITH THE JUSTICE SYSTEM. MAJOR DIFFICULTIES IN COMBATTING WHITE-COLLAR CRIME ARE THE ABSENCE OF A PUBLIC AGENCY FOR THIS AREA IN CANADA, DISCOURAGEMENT OF PROFESSIONAL ORGANIZATIONS AND GOVERNMENT AUTHORITIES BECAUSE OF POLITICAL FACTORS, AND THE SHORTAGE OF EXPERTS ADEQUATELY TRAINED FOR MULTIDISCIPLINARY TEAM WORK IN LAW, ECONOMICS, AND SOCIOLOGY. BIBLIOGRAPHIES, TABLES, AND NOTES FOR EACH ARTICLE ARE FURNISHED. --IN FRENCH. (KMD)
