We propose a network model of firm volatility in which the customers’ growth rate shocks influence the growth rates of their suppliers, larger suppliers have more customers, and the strength of a customer-supplier link depends on the size of the customer firm. Even though all shocks are i.i.d., the network model produces firm-level volatility and size distribution dynamics that are consistent w...

This paper studies a simple dynamic investment decision problem of a firm where adjustment costs have capital size effects. This type of setting possibly results in multiple steady states thresholds and a discontinuous policy function. We study the global dynamic properties of the model by employing the Hamilton-Jacobi-Bellman method and dynamic programming that help us in the numerical detecti...

Health Insurance Benefit Mandates and the Firm-Size Distribution By 2010, the average US state had passed 37 health insurance benefit mandates (laws requiring health insurance plans to cover certain additional services). Previous work has shown that these mandates likely increase health insurance premiums, which in turn could make it more costly for firms to compensate employees. Using 1996–201...

We show that the stylized facts of the Firm Size Distribution (FSD) by age cohorts, as shown in Cabral and Mata (2003), bind within 4-digit manufacturing industries in the UK and Belgium. As in Klepper and Thompson (2006) and Sutton (1998), we explore whether time to build a portfolio of products is a mechanism that relates age to firm size. While inter industry diversification, to some extent,...

This paper analyzes the effects of intra-firm bargaining on the formation of firms in an economy with imperfect capital markets and contracting constraints. In a one-sided matching equilibrium endowment inequality induces a heterogenous distribution of firm sizes allowing for firms both too small and too large in terms of efficiency. The findings connect well to empirical facts such as the miss...

The distribution of firm sizes is known to be heavy tailed. In order to account for this stylized fact, previous economic models have focused mainly on growth through investments in a company's own operations (internal growth). Thereby, the impact of mergers and acquisitions (M&A) on the firm size (external growth) is often not taken into consideration, notwithstanding its potential large impac...

We use rich brand level retail data to demonstrate that the firm size distribution in Carbonated Soft Drinks is mainly an outcome of the degree to which firms own a portfolio of brands across segments of the market, and not from performance within segments. In addition, while the number of firms in each segment is limited by segment size relative to sunk cost and competition in a segment, idios...
