One of the key characteristics of the United States economy is the drive towards entrepreneurship and growth. Business firms can be established relatively easily and quickly as they considered a key engine for national progress and prosperity. The contribution of small firms to investment, innovation, output, exports, and income is well documented in business literature. Just as it is easy to start a new business venture in the U.S., many firms are also forced out of the market for a variety of reasons. In some past years, the deaths of micro firms outnumbered micro firms births. This study was intended to explore the influence of key external economic factors on the failure (i.e., deaths) of micro firms in the country. The traditional views attribute this unfortunate phenomenon largely to the firms’ internal dynamics, including incompetent management, scarcity of capital, and inadequate infrastructure. The impact of external aggregate economic forces has hardly been fully investigated. The findings of the study indicate the absence of a direct link between external macroeconomic factors and the deaths of micro firms in the United States.
