Abstract
In this chapter, I compare a capital budgeting model of bank lending based on stock valuations to a supply/demand model based on an interest rate channel for France and Germany using non-nested hypothesis tests and omitted variables tests. For France, the results of these two statistical tests indicate a strong rejection of the supply/demand model with an interest rate channel and non-rejection of the capital budgeting model. The results for Germany are mixed. For Monetary Financial Institutions, the non-nested hypothesis test and omitted variables test rejected both models. For the banking sector of Monetary Financial Institutions, both tests rejected the supply/demand model but did not reject the capital budgeting model. Do these results have any implications for policy? If volatility in share prices leads to volatility in bank lending which in turn leads to volatility in real economic activity, then governments may want to begin thinking of ways to dampen the volatility in the stock market.

There is a minority view that the direction of causation is from economic development to financial development. For this view, see Robinson (1952) and Manning (2003). Moreover, Acemoglu et al. (2001), Rioja and Valev (2004), and Rousseau and Wachtel (2006) argue that the finance/growth link is becoming weaker over time for developed countries like the US.

In other words, we assume that the managers of the firm cannot instantaneously change R(d,ER) by instantly changing its investments for “time to plan” and “time to build” reasons. Consequently, market values of debt (and as we will see later, equity) securities can be temporarily different than book values.
- 5.
As the firm/economy moves closer to z′ by downsizing, the difference between market and book values for both debt and equity securities becomes smaller. When the firm/economy reaches z′ market values will equal book values and that will be the signal for managers to stop the downsizing. When at point z′ the firm/economy is in a recession equilibrium according to this model.

The financial leverage of nonfinancial enterprises that is predicted by this theory to be countercyclical is long-term financial leverage. What about short-term debt like bank loans that is predicted in this chapter to be procyclical? Are these two predictions contradictory? Bank loans are risky assets on the balance sheets of banks. As such the model predicts they will be procyclical. Bank loans are also liabilities on the balance sheets of bank loan customers such as nonfinancial enterprises and households. In the case of nonfinancial enterprises short-term bank debt in our model is more like equity than long-term debt. This is because short-term lenders like banks have the option of getting in or out of a loan to a borrowing company at book value at higher frequencies than long-term bondholders where the option is to get in or out at continually changing current market prices before the redemption date. When a short-term bank loan matures the decision by the bank to renew or not depends on the borrower (particularly small and medium size companies) presenting an acceptable business plan; that is, an operating plan and a financing plan. By continually requiring the borrowing firm to produce an updated business plan bank control of the business plan of the borrowing firm rivals that of equity holders and far exceeds that of long-term bondholders. Control rights are another way to distinguish among financial claims on firms. Equity claims contain the most control rights and long-term funded debt the least. Short-term bank loans are somewhere in-between but closer to equity. For that reason we include bank loans along with equity to be in the denominator of the leverage ratio of firms. Research by Dichev and Skinner (2002) indicates that banks exercise this control by setting covenants in loan agreements tightly so that they are frequently breached, roughly 30 % in their sample. Typically, the bank waives the resulting noncompliance but instead uses it as an opportunity to discuss the borrowing firm’s business plan further. In this way, banks, like the board of directors representing stockholders, frequently monitor the ongoing business strategy of borrowing firms.

Why this particular assignment of decisions to claimants? In our model it is the case (as reflected in Fig. 1) that entrepreneur investors have a better understanding of the technology underlying the assets of the all equity firm they created than subsequent debt investors. In addition the variable residual nature of equity claims on the firm allows subsequent less risk averse investors to benefit from their (or their agent’s) understanding of the technology. More risk averse debt investors can protect themselves with a financial contract that allows them to determine the financial strategy of the firm. For a numerical example on how the financial contract might work see Krainer (2014).

Before the Great Crisis empirical work on demand models of bank lending included Calza et al. (2003), Eickmeier et al. (2006), and Frommel and Schmidt (2006) among others. After the Crisis work on these models include Sorensen et al. (2009), Kooths and Rieger (2009), Carpenter and Demiralp (2010), Campello et al. (2012), Kahle and Stulz (2011), among many others.

Two hypothesized specifications H1 and H2 for an economic variable is said to be non-nested if it is not possible to derive either one from the other by means of a set of parametric restrictions.
- 10.
Since the equity leverage variable \( \Delta {\left(\frac{\mathrm{Tier}1}{A}\right)}_t \) was not significantly different from zero in the OLS test of H1 and H2, we dropped it from the non-nested hypothesis test in the bottom half of Table 3.
- 11.
It should also be noted that the standalone specification for H1 in the top half of Table 5 for commercial banks was not as supportive of the capital budgeting model of bank lending as the standalone specification for MFI lending in Table 4 in that the positive estimated coefficient on (SP,CDAX) was not statistically significant at the 5 % significance level.
