Penicillin has become a front-line tool of medicine around the world. It has saved many lives, and its availability and efficacy has freed people from fear of infection by common bacteria. The growing problem of penicillin resistance in bacteria has reduced its efficacy, but it is still useful in combating many infections.
Penicillin was a miracle drug during World War II - it saved millions of soldiers' lives that otherwise would have died from infections of battle wounds. It was the first antibiotic, so it also paved the way for other classes of antibiotics that have reduced infectious death rates around the world. Without penicillin, our modern world would look very different - high rates of infectious death, a significantly lower life expectancy, etc.
Economically? Well there really is no exact answer to that question. It had improved the medical industry, but that's really all. There's no frank way to say how it has improved the world economically.
Antibiotics have made peoples lives better because they help people get over certain diseases and illnesses. Before there was modern medicine people died over the simplest infections and diseases and there general lifespan was hindered.
Penicillin has been used to treat many illnesses for many years, allowing more people to live, defeating the process of natural selection, and causing humans with inferior genetic strains to be able to survive longer and therefore reproduce and create children that will very likely get illnesses that need to be treated with penicillin.
