While at school I have been keeping myself abreast of the global recession which resulted in the collapse of several reputed financial institutions, decline in growth of economy, increase in unemployment, loss of savings, to name a few. These incidents led me to decide on a career in finance and economics.
^I personally find this opening rather cliched. How did such events lead you to decide on a career in finance and economics? In fact, why would such events lead you to decide on a career in finance and economics? Perhaps an explanation on how such events led to your interest in finance and economics would support your claim.
EDIT:
*For the most part, your essay is generally cliched and contains a bit of unnecessary and irrelevant information. Just say why you want to study at Ohio State, how will it help you if you studied there, and what makes Ohio State special for you.
