Here is a little info on your subject. Hope it helps. Best of luck.
Social Effects
The marriage rate rose sharply -- in part due to predatory men marrying rich orphans and widows.
The birth rate also rose, though recurrences of the plague kept population levels reduced.
There were notable increases in violence and debauchery.
Upward mobility took place on a small scale.
Economic Effects
A surplus of goods resulted in overspending; it was swiftly followed by a shortage of goods and inflation.
A shortage of laborers meant they were able to charge higher prices; the government tried to limit these fees to pre-plague rates.
Effects on the Church
The Church lost many people, but the institution became richer through bequests. It also grew richer by charging more money for its services, such as saying mass for the dead.
Less-educated priests were shuffled into jobs where more learned men had died.
The failure of the clergy to help the suffering during the plague, combined with its obvious wealth and the incompetence of its priests, caused resentment among the people. Critics grew vocal, and the seeds of the Reformation were sown.
From msn encarta:
The plagues also brought economic changes. The death of so many people concentrated wealth in the hands of survivors. In many cases those workers who remained alive could earn up to five times what they had earned before the plague. In the towns, plague had the effect of consolidating wealth somewhat, especially among the middle class. As plague destroyed people and not possessions, the drop in population was accompanied by a corresponding rise in per capita wealth. Large increases in spending in the towns at this time are well documented. Profits, however, for landlords and merchants declined as they found themselves having to pay higher wages and getting less when they sold their products.
