8 Lewis-Beck and Tien Jobs Model: Forecast for 2004 Dependent variable: Percent of two-party vote received by candidate of incumbent party. Explanatory VariablesCoefficient (t-ratios in parentheses) Plugging in the numbers for 2004 Constant31.16 (12.6)31.16 Presidential Popularity0.26 (8.2)0.26*47 GNP x Elect1.58 (4.7)1.58*1.32 Incumbent Party Advantage2.30 (4.3)2.30*1 Jobs0.59 (3.1)0.59*3.67 Adjusted r Standard error1.52 Durbin-Watson1.28 Number of cases13 ( ) Prediction: 49.9% Coding of Variables: Presidential Popularity is Gallup approval rating of the President measured in the first July poll before the election. GNP x Elect is the growth rate in real GNP during the first 6 months of the election-year multiplied by whether an incumbent President is running (coded 1) or not running (coded 0.5). Incumbent Party Advantage is coded as follows: 1 if incumbent candidate is the elected president (1956, 1972, 1980, 1984, 1992, 1996) or following a president who died in office (1948, 1964); 0 if incumbent party candidate has a tolerable association with the previous president (1952, 1976, 1988); and -1 if incumbent party candidate and the president are not united (1960, 1968, 2000). Jobs is growth in jobs over first 3.5 years of presidents term. Calculated as follows: (# employed in June of election year - # employed during January of inauguration year) # employed during January of inauguration year and multiply that by 100.
