- 요약This thesis consists of three essays on macroeconomics and firm dynamics. Chapter 1 studies the role of customer and supplier acquisition in shaping production network structure and aggregate productivity. Using transaction-level data from a large Indian state, we document lifecycle patterns of customer and supplier networks. Motivated by these patterns, we develop a model of endogenous network formation where heterogenous firms undertake costly acquisition of customers and suppliers over the lifecycle. We study the normative properties of the model and find that the decentralized equilibrium is inefficient due to vertical and search externalities. Inefficient pricing and acquisition choices lead to quantitatively large aggregate productivity losses. We use the model to study how differences in acquisition technology map to productivity differences. We find that improvements in acquisition technology can generate sizable productivity gains, and that improvements in allocative efficiency are central for delivering these gainsChapter 2 studies the role of financial frictions in generating aggregate productivity losses in a dynastic setting. Existing work has noted that aggregate productivity losses are small when idiosyncratic productivity shocks are highly persistent, as agents are able self-finance. In contrast to existing work, I study the role of self-financing using a dynastic model in which finitely-lived generations are altruistically linked. In the model, the size of aggregate productivity losses depends not only on the persistence of idiosyncratic productivity shocks, but also on the transmission of productivity between generations and the level of intergenerational altruism. Quantitatively disciplining the model, I find that financial frictions generate large aggregate losses, even when idiosyncratic productivity shocks are highly persistent.Chapter 3 develops a model of endogenous growth through imitation. I allow for imperfect learning in the sense that agents may not be able to imitate every idea they come across. I derive restrictions necessary on the learning technology to ensure the existence of a balanced growth equilibrium. The main result of the paper is to show that a balanced growth equilibrium exists as long as the learning technology allows agents to learn any idea they come across with non-zero probability.
