Chapter 1 documents the evolution of a domestic banking system from inception to maturity, defined in terms of its turnover dynamics. I digitize multiple novel historical sources for Canada from the founding of its first bank in 1817 up to 1933, after which there was no turnover event for twenty years. I provide a broad set of stylized facts related to three themes: Turnover and market shares, branching and financial networks, and portfolio choices. Regarding major results related to the first theme, I show a tendency towards market concentration. The industry shows an inverted ``V-shaped" evolution for the number of incumbent banks that converges to having just ten large banks down from a peak of 51. Overall, while smaller banks fail and get liquidated, large banks merge with medium-sized banks. Market shares are also quite persistent since banks tend to stay in the same market share quartile across 5-year windows. Next, in terms of branching and financial network facts, I show that banks tend to branch more in locations with higher populations and with access to a means of transportation. Moreover, a higher proportion of branches in a Province predicts a higher chance of having more branches in that same Province next year. I also show the evolution of the correspondent financial network over the life-cycle of the industry. It starts almost disconnected with few nodes and links, evolves towards an almost fully connected one with many nodes and links, and ends again almost disconnected with few nodes and links. Moreover, most links originate from smaller banks to a handful of large banks, with fewer links among the largest banks. What predicts having a correspondent or respondent relationship in a particular Province? First, having a branch located where a Provincial Clearing House increases the chance of having a respondent for that Province, and not having a branch in that location increases the chance of having a correspondent there. Second, if a bank has at least one branch in a Province that is connected by train with the other Province, that bank has a higher chance of having both a correspondent and a respondent in this other Province. I interpret this finding as one related to the idea that transportation routes lower trading costs and increase inter-location trade. Third, while the proportion of branches located in a Province doesn't predict having a correspondent there, it does predict the chance of providing correspondent services in that Province to a respondent. Finally, in terms of portfolio choices, overall, I find banks that branch to a higher number of locations have lower loan and liquidity risk and higher leverage, which is consistent with a ``diversification" channel on both sides of the balance sheet. Moreover, larger banks have a larger portfolio share of liquid and safe assets, above and beyond their needs for liquidity management purposes. I interpret this as larger banks having a larger ``precautionary" buffer due to incentives to (partially) internalize systemic risk. Chapter 2 provides a search theoretic model to provide insights on whether private banks are obsolete from a technological point of view. Compared to historical manifestations of base monies like spices, bullion, or coins, today's state of technology and institutions related to base monies seems to make private banks more likely to become obsolete as the main providers of retail payment instruments and services. To provide insights into this issue, I build a monetary search model where transferring the medium-of-exchange (MOE) entails dealing with transfer costs, imperfect supply elasticity, and asymmetric information in its value. Banks are special because they are experts in assaying the quality of the MOE and have access to a retail payment infrastructure. The latter allows banks to issue unlimited unforgeable and cheaper-to-transfer debt but at the expense of possible discounts motivated by the debt heterogeneity created when money is provided by more than one institution. Given this model, I first show what I call the ``Two Worlds" result, which allows me to partition the parameter space into two sub-spaces that speak to the relevance of banking in the competitive equilibrium. My main result suggests that the extent of near-future obsolescence depends on a sort of ``race" between private banks and Central Banks on future innovations in retail payments. Formally, suppose I start from a parameterized model consistent with being in a Banking World, where only bank debt is used for exchanges. Then, if asymmetric information and transfer costs on the MOE converge to private standards, even with an arbitrarily good private payment infrastructure, the environment converges into a Non-Banking World. In this world, agents demand only the MOE for payments. However, I also show that if instead MOE transfer costs become arbitrarily close but still higher than private standards, and bank debt transfers become as homogeneous as transferring funds within a Central Bank, then the environment remains a Banking World. Therefore, my main results suggest that ultimately the near future obsolescence of private banks depends on whether they offer fast and seamless bank debt transfers that resemble what would be like transferring debt within the same institution like a Central Bank. These private innovations would also need to compensate for future public innovations in the cost of retail transfers of Central Bank debt
