In the classical principal-agent problem, a principal hires an agent to perform a task. The principal cares about the task's output but has no control over it. The agent can perform the task at different effort intensities, and that choice affects the task's output. To provide an incentive to the agent to work hard and since his effort intensity cannot be observed, the principal ties the agent's compensation to the task's output.

The banking legislation of the 1930s took very little time to pass, was unusually comprehensive, and unusually responsive to public opinion. Ironically, the primary motivations for the main bank regulatory reforms in the 1930s (Regulation Q, the separation of investment banking from commercial banking, and the creation of federal deposit insurance) were to preserve and enhance two of the most disastrous policies that contributed to the severity and depth of the Great Depression — unit banking and the real bills doctrine.

Financial crises appear to be a common and fairly constant feature of the economic cycle. Banking crises, a distinct subset of financial crises, consist either of panics, moments of temporary confusion about the unobservable incidence across the financial system of observable aggregate shocks, or severe waves of bank failures which result in aggregate negative net worth of failed banks in excess of one percent of GDP.

We discuss the evolution in macroeconomic thought on the monetary policy transmission mechanism and present related empirical evidence. The core channels of policy transmission — the neoclassical links between short-term policy interest rates, other asset prices such as long-term interest rates, equity prices, and the exchange rate, and the consequent effects on household and business demand — have remained steady from early policy-oriented models (like the Penn-MIT-SSRC MPS model) to modern dynamic, stochastic general equilibrium (DSGE) models.

In this paper, we develop a structural model that captures the interaction between the cash balance and investment opportunities for a firm that already has some debt outstanding. We consider a firm whose assets produce a stochastic cash flow stream. The firm has an opportunity to expand its operations, which we refer to as an "option the expand." The exercise cost of the option can be financed either by cash or costly equity issuance.
