The importance of firm size in aggregate output has been highlighted by global studies. While this has relevance to investment as well, this focus has also been extended to the topic of firm size. Moreover, large-firm data sets using administrative sources are becoming available, making it possible to construct full firm-size distributions. Consequently, it has become easier to examine the effects of different size thresholds and levels of concentration on firm investment. In this article, we will analyze this issue and identify the key factors that influence firm size and investment.
Several studies have found that firm size affects aggregate investment. In the US, large firms are more capital-intensive and younger, while small firms are likely to be present in industries that require significant capital investment. However, it is also important to remember that firms of a similar size are likely to invest more money than larger ones. To this end, it is important to distinguish between large and small firms when comparing their investment levels. For example, smaller firms tend to invest more in technology than larger ones, and this makes them a more attractive investment opportunity.
There are many variables that affect firm investment. A study by Gabaix (2011) highlights the role of size in aggregates. According to Gabaix, a study of US firms found that smaller firms are more sensitive to economic cycle changes than large firms. Moreover, studies have shown that small firms suffer greater fluctuations in revenue, sales, and investment, compared to large firms. Consequently, a COVID-19 pandemic that affected a small number of companies is likely to have had a greater impact on them than on large-sized ones.
Uncertainty can also affect firm investment. Some studies indicate that small-sized firms are more sensitive to uncertainty, and changes in the economic cycle are more apparent in small firms. Additionally, recent research indicates that smaller firms are more likely to experience larger swings in investment than larger firms. Likewise, these studies show that large firms account for a higher share of aggregate investment than smaller firms. This suggests that firm size is a proxy for firm-size and the set of investment opportunities.
The size of firms also influences aggregate investment dynamics. As a result, firm size and investment levels are affected differently by the same circumstances. Similarly, firm size and industry size determine the nature of the environment and the nature of investment. Generally, large firms account for a large percentage of the economy’s economic activity and hence, they are more likely to respond to these conditions than smaller firms. This is important in a variety of contexts.
Another factor affecting firm size is uncertainty. Compared to large firms, small firms are more responsive to changes in the economic cycle. For example, the size of a firm is a proxy for its investment opportunities. In the United States, small firms have greater investment opportunities. And while large firms have larger investments, their investments are more expensive. The effect of uncertainty on firm size is stronger in the United States. So, small firms are more affected by the uncertainty in the economy, and they should invest accordingly.
